Effect of Yeast Autolysate Feed Additive on Performance of Suckling and Growing Buffalo Calves
The present study investigates the effect of yeast (Saccharomyces cerivisea) autolysate (YA) on digestibility, rumen fermentation specially rumen microflora, blood parameters and growth of both suckling and growing buffalo calves Twelve suckling calves with an average body weight of 35.5±0.5 kg were randomly divided to three groups (4 calves each). The experimental period was divided into two phases, the first phase lasted 90 days after calving whereas, the second phase lasted 150 days started by weaning calves (90 days of age). In the first phase, animals in all groups suckled whole milk (WM) twice daily in addition to starter and berseem. In the second phase, animals were fed the basal rations composed of concentrate feed mixture (CFM), rice straw (RS) and berseem (Br). The experimental rations were R1: WM (control), R2: WM+ 5 ml of YA/h/d (5ml equal 1 gram of YA) and R3: WM+7.5 ml of YA, in the first phase. While during the second phase, the rations were R1: basal ration (control), R2: basal ration +35 of YA and R3: basal ration +50 ml YA. The results showed that addition of YA increased (P<0.05) digestibility of CP and CF, but it had no significant effect for other nutrients. The nutritive value as TDN was significantly (P<0.05) increased by addition of YA. Blood parameters (GPT, GOT and creatinine) and rumen fermentation were not affected by addition of YA except rumen pH which was significantly (P<0.05) higher for animal fed rations contained YA compared to the control. In the first phase, weaning body weight was significantly (P<0.05) increased by YA addition, on other hand, final body weight and ADG were not affected in the second phase. Feed conversion, daily profit, relative feed cost and relative daily profit were improved by treatment. Bacteriological examination revealed that the addition of YA decreased total aerobic bacterial count but it significantly (P<0.05) increased Lactobacillus count in feces of treated suckling calves with YA compared with control. Also, Lactobacillus count was significantly increased while; total number of aerobic bacteria was decreased in rumen fluid of growing calves by addition of YA. In vitro sensitivity of YA on the isolated three E. coli strains from control group revealed that there is strain variation in this respect as one strain (O27) showed the lowest count after treatment with yeast (less than 10 CFU) and the other two strains (O127 and un- typed strain). Results obtained revealed that using YA as feed additives for suckling and growing buffaloe calves tended to increase average daily gain, improved feed conversion and get more profit relative to feed cost or a relative daily profit. Moreover, addition YA appeared to decrease of aerobic bacteria with increase Lactobacillus.

Growth Performance, Liver and Kidney Function, Lipid Metabolism and Thyroid Hormones of Growing Rabbits Treated with Different Types of Metabolic Agents
Aim of the present study was to evaluate the effect of treatment of L-carnitine or coenzyme Q10 on growth performance, liver and kidney functions, thyroid hormones, and economic feed efficiency of growing rabbits fed diet supplemented with propolis. Total of 60 weaned New Zealand white rabbits (5 wk of age and 702.58±12.70 g live body weight) were divided into 3 similar groups (20 in each, 10 from each sex). Rabbits in the 1st group were fed commercial pelleted diet (CPD) without any treatment and served as control (G1). While, rabbits in the 2nd and 3rd groups were fed CPD (18% CP, 13% CF and 2800 Kcal/kg) supplemented with 0.5 g propolis (PR)/kg and orally administrated with 10 mg CoQ10/kg LBW (G2) and 40 mg L-carnitine (LC)/kg LBW (G3), respectively. Feeding rabbits was ad. Libitum, while drinking water nipples were present in each cage. From 5-13 wk of age as an experimental period, rabbits were treated by each combination twice weekly. Average of body weight (LBW), feed intake (FI) and daily gain (ADG), rate of feed conversion (FC) and viability, relative growth rate (RGR) and performance index (PI) were determined. At 13 weeks of age (end of experiment), blood samples were taken from 3 slaughtered males in each group to determine total proteins (TP), albumin (AL), creatinine (CR), urea (UR), cholesterol (CH), HDL, LDL and triglycerides (TG) concentrations, AST and ALT activity and T3 and T4 concentrations. Weights of liver, kidney and body fat were recorded. Small samples from liver and kidney tissues were taken to examine the histological structure. Results showed that final LBW, ADG, FI, RGR and FCR were not significantly affected by treatment, although these parameters tended to be the highest in G2, moderated in G3, and the lowest in G1, being higher in male than female rabbits. All growth performance parameters was not significantly affected by the interaction between treatment and sex of rabbits. Effect of treatment was not significant on absolute and relative weight of the liver and kidney. Effects of treatment on concentrations of TP, AL, GL, CR, UR, CH, HDL, LDL, TG, T3, T4, AL/GL ratio and ALT activity in blood serum were not significant, while AST activity reduced (P<0.05) in G2 and G3 than in G1. Based on the histological examination, rabbits in treated groups (G2 and G3) showed normal liver and kidney functions. Average weight of abdominal fat was higher (P<0.05) in G1 than in G2 and G3. Subcutaneous fat as absolute or relative weight of total fat was not significant. In conclusion, treatment of growing rabbits during marketing period (5-13 wk of age) with a combination of propolis and coenzyme Q10 or L-carnitine twice/week led to functional liver and kidney with normal lipid profile. These findings were associated with remarkable improvement in growth performance parameters

Effect of Some Natural Antioxidants on Growth Performance, Blood Parameters and Carcass Traits of Growing Rabbits Under Egyptian Summer Condition
The current study aimed to evaluate the effect of treatment with combination of royal Jelly (RJ) plus green tea (GT) or propolis (PR) plus GT on thermo-physiological response, growth performance, blood biochemicals and carcass traits. Total of 60 NZW weaned rabbits (5 wk of age and 703.03±11.59 g LBW) were assigned into three similar groups of 20 rabbits in each (10 males and 10 females). Rabbits in the 1stand 2nd groups were fed complete feed diet (CFD) supplemented with 2 g GT/kg and orally treatment twice/week with 150 mg RJ/kg (G1) or 0.5 g PR/kg LBW (G2). However, rabbits in the 3rd group were fed the same CFD without any supplements and orally treated with one ml saline and served as a control group (G3). Throughout the experimental period (August and September months), temperature humidity index (THI), rectal temperature (RT), LBW, feed intake (FI), viability rate and performance index (PI) were recorded, and daily weight gain (DWG) and feed conversion ratio(FCR) were calculated at 5-9, 9-13 and 5-13 age intervals. Blood samples were collected from three males from each group for determination of total proteins (TP), albumin (AL), glucose, cholesterol, triglycerides, high density lipoproteins (HDL), low density lipoproteins (LDL), creatinine, urea, triiodothyronine (T3) and tetraiodothyronine (T4) concentrations, as well as activity of aspartate (AST) and alanine (ALT) transaminases in serum. At 13 wk of age, three males from each group were slaughtered to evaluate carcass traits. Meat samples from hind limb were taken for chemical analysis. Results show that rabbits extremely severed from heat stress throughout all months studied. RT reduced in G2 (P<0.05) and G1 (P≥0.05) as compared to G1, being better in males than in females. Both G1 and G2 showed marked improvement in LBW, DWG, RGR, FI, FCR and PI as compared to G3, being with the best G2, in particular, at 5-9 wk of age. VR was the highest in G1, and higher in females than females only in G2. Concentrations of TP, AL, GL, AL: GL ratio, total cholesterol, triglycerides, LDL, HDL, creatinine and urea as well as activity of ALT in blood serum were not affected by treatment. Serum glucose concentration was higher (P<0.05) in G2 than in G1, while both groups did not varied significantly from that in G1. Also, AST activity in serum reduced (P<0.05) in G1, but did not differ in G2 as compared to G3. Concentration of T3 and T4 was higher (P<0.05) in G1 than in G2 and G3. All carcass traits and meat composition were not affected significantly by treatments. Economic feed efficiency was the best in G1, followed by G2, and the lowest in G3.In conclusion, treatment of weaned rabbits during growing period under summer ambient temperature from 5 to 13 weeks of age with green tea in combination with royal jelly or propolis twice/week resulted in improving growth performance, viability rate and economic feed efficiency without adversely effects on rabbit health, in particular, at 5-9 wk age interval. A combination of royal jelly with green tea showed the best results

Effect of Aqueous Extracts of Moringa oleifera leaves or Arctium lappa Roots on Lipid Peroxidation and Membrane Integrity of Ram Sperm Preserved at Cool Temperature.
This study aimed to investigate effect of addition of different levels (0, 100, 500 and 1000 µg/ml) from Moringa oleifera leaves (MOL) or Arctium lappa L. roots (ALR) extracts, as antioxidants to ram semen extender on sperm characteristics, lipid peroxidation and enzyme activity in seminal plasma of ram semen preserved at cool temperature (5°C)for 48 hours. Four adult Rahmani rams were used. Semen was collected from all rams using an artificial vagina once a week for 8 weeks. Lecithin soybean based-extender was divided into seven portions; control (T1), 100 (T2), 500 (T3) and 1000 (T4) µg MOL extract/ml or 100 (T5), 500 (T6) and 1000 (T7) µg ALR extract/ml extender. In each treatment, percentage of progressive motility (PM), livability (SL), and abnormality (AB) were determined. Also, percentages of spermatozoa having curled tails or chromatin damage were calculated. Polyphenols and flavonoid compounds in MOL or ALR extracts were identified. Concentrations of total antioxidant (TAO) and malondialdehyde (MDA), and activity of acid phosphatase (ACP) and lactic dehydrogenase (LDH) were determined. Results showed that both extracts revealed higher content of most phenolic compounds in ALR than in MOL extract, but Pyrogallol compound showed the highest level of phenolic compounds in both MOL and ALR extracts. ALR extract showed higher contents of Narengenin, Rutin, Quercetin, Apigenin and Luteolin and lower contents of Hisperdin, Romarinic acid, Kampferol and Hesperitin than in MOL extract. Only overall percentages of SL and AB improved (P<0.05), while percentage of sperm with chromatin damage increased (P<0.05) in T7 as compared to T1. Overall percentage of PM and curled tail of spermatozoa did not differ in T7 compared with T1, while T6 showed poorer (P<0.05) results than in T1. All sperm characteristics studied showed deleterious effect (P<0.05) by increasing storage period. The effect of interaction between treatment and storage period was not significant on all sperm characteristics. Concentrations of TAO and MDA as well as ACP and LDH activities tended to be higher (P≥0.05) in seminal plasma of semen in all treatments. Effect of storage period or its interaction with treatment was not significant on concentrations of TAO and MDA as well as ALP and LDH activities. The present results showed that adding 1000 µg of Arctium lappa roots extract improved livability and abnormality with appropriate progressive motility and response to HOS-t of spermatozoa in Lecithin soybean based-extender of ram semen preserved at cool temperature (5°C) for 48 hours as compared to un-supplemented or those supplemented with 100 or 500 µg of Moringa oleifera or Arctium lappa.

Genetic Improvement Using the Selection Indices for Some Productive and Reproductive Traits in Friesian Cattle Raised in Egypt
A total of 1600 lactation record during the years 2000 to 2007 were collected to represent 554 cows were inseminated 84 sire in Alkarda station in Kafr El-Sheikh of the Institute of Animal Production Research, Agricultural Research Center, Egypt . The objective of this study was to estimate the genetic and non-genetic parameters, breeding value (BV) for some productive and reproductive traits, determine economic values for various production traits total milk yield (TMY), lactation period (LP),calving interval(CI) and dry period (DP) in dairy production, as well as to determine total economic selection index. The research is based on data which include 1600 lactations of 554 cows. Data were collected during the period 2000 – 2007. The derivative-free restricted maximum likelihood (REML) procedure was used to determine heritability, genetic correlation and breeding value of the studied traits. It was determined that within economic selection index the most important trait is milk yield, while values for other traits are almost negligible. Selection indices using one phenotypic standard deviation as REV1 and limit method as REV2. The results indicated that non genetic factors affecting (TMY), (LP), (CI),(DP) and interaction between (parity & season), (parity& year ), (year & season) had highly significant (p<0.001) effect on those traits except the effect of CI and DP . The overall means (Mean) of TMY, LP, GI and DP were 3158.8 kg; 343.5, 453.9 and 78.5 day, respectively. Heritability estimate (h2) for TMY, LP, GI and DP were 0.33, 0.08, 0.07 and 0.04, respectively. Phenotypic correlation between each two traits ranged from -0.11 to 0.29; and genetic correlation between each two traits ranged from -0.29 to +1 . Ranges estimates breeding values(BV) of cows estimated for TMY, LP,GI and DP were 1034.8, 522.5, 223.6 and 46.5, respectively in herd which was higher than those for sire 573.8, 152.4,127.9 and 19.6 and those fore dam 1034.8, 445.2, 154.3 and 29.8, respectively. general indices I1 and I12 incorporating TMY, LP, GI and DP was the best (RIH = 0.63) and it is recommended if the selection was exercised; in addition there are high similarity of genetic gains under the two different groups of economic values REV1 and REV2.General guide was the most efficient use of my way to derive economic value I1 = 0.36216 (TMY) -0.77931 (LP) + 0.83967 (CI) - 3.96728 (DP). I12 = 0.34412 (TMY) - 0.46265 (LP) + 0.34458 (CI) - 1.12974 (DP). This study will help the breeders to select the best dairy animals which will be used for production. The future generations based on genetics of milk production and reproduction traits in early lactation.

Hepatoprotective Effect of Coumarin and Chlorophyll Against Aflatoxicosis in Rat
Aflatoxin contamination of animal diet is still a major problem for breeders since it hasadverse effects on animal health and productivity. This study was carried out to investigate the effect of using coumarin and/or chlorophyll in rat diet against aflatoxicosis. Fifty four rats were randomly assigned into 7 groups ''6 rats each'' and group 5 ''12 rats''. Group 1 was negative control. Group 2 received water with coumarin 0.5%. Group 3 received water with chlorophyll 0.5%. Group 4 received water with coumarin 0.5% and chlorophyll 0.5%. Group 5-8 received basal diet with aflatoxin B1 1000 ppb. Group 6-8 were administered similar treatments as groups 2-4. The experiment ended after 8 weeks. Water and feed consumption were measured and feed conversion rate were calculated. Random glucose level, total lipid, total cholesterol, triglyceride, total protein, ALT , AST, creatinine and urea were determined in serum. Histopathological examination of liver, kidney and pancreas was performed. The conversion rate was significantly low in group 5 compared to groups 6-8. The serum glucose, cholesterol, AST and ALT were elevated in group 5 compared to groups 6-8. The liver lesions observed in group 5 represented in vacuolation and necrosis were alleviated in groups 6-8. The necrosis and inflammatory cells infiltration in pancreas of group 5 were absent in groups 6-8. In conclusion, the coumarin and or chlorophyll possessed a hepatoprotective effect against aflatoxincosis.

Effect of Stocking Density and Probiotic Supplementation on Broiler Performance
An experiment, with a factorial arrangement of treatments (3×3), was conducted to evaluate the response or Ross broiler chicks to three stocking densities and three levels of probiotic added in drinking water. Two basal diets were formulated and fed to chicks during the starter and finisher periods. A total of 540 chicks was randomly divided into nine experimental groups, kept in floor pens at three stocking densities (10, 12 or 14 birds/m2) and given probiotic (0.0, 1.0, or 2.0 ml/liter of water). Each group had three equal replications. All birds had free access to feed and water, and managed similarly. Growth performance, economic efficiency, carcass traits and blood parameters were determined. Increasing stocking density from 10 to 14 birds/m2 during the entire experimental period led to significant increases in feed intake, mortality rate, and plasma total lipids, triglycerides and cholesterol but negatively affected feed conversion ratio, body weight gain, and concentrations of total protein, albumin and globulin in blood plasma. But stocking density did not affect carcass traits of birds. Water-added probiotic positively affected feed intake, feed conversion ratio, body weight gain and mortality rate, and caused a significant increase in total protein, albumin and globulin but significantly reduced plasma levels of total lipids, triglycerides and cholesterol. Added probiotic, however, had no effect on carcass traits. When growth performance and economic aspect are taken into consideration, it can be concluded that a stocking density of 10 birds/m2 proved to be the best level. Probiotic addition produced further improvement in growth and economic efficiency of broiler chickens.

Effect of Vit. E Supplementation to Pregnant Ewes Ration on Some Blood Biochemical Components in Ewes and Their Offspring’s
Thirty six pregnant Rahmani ewes with an avg. 33.7 kg LBW and 3 years old age were used to investigate the effect of vitamin E daily supplementation to pregnant ewes at late gestation and early lactation on the productive performance and some biochemical blood constituents of treated ewes and their offspring’s. Experimental animals were randomly assigned (28 days prepartum) to three nutritional groups; the 1st one served as a control (nil vitamin E supplement). The 2nd and 3rd groups were daily and individually administrated 400 IU of α-tocopherol acetate (vitamin E), 28 days prepartum (T1) and for 28 days pre and 28 days postpartum (T2). Experimental animals were offered their daily requirements during pregnancy and early lactation according to (NRC recommendations, 1985). Blood samples were routinely withdrawn from ewes and their offspring’s to assess some blood measurements i.e. (GSH-Px), LDH, ALT, AST, Total protein and globulin fractions. Results obtained indicated that, Vitamin E supplementation to pregnant ewes during late gestation led to affect significantly (p<0.05) ewes and lambs (GSH-Px) enzyme activity, increase (p<0.05) serum total protein and globulin concentration value in favor of the two supplemented ewes groups and the corresponding offspring’s. However, non-significant differences (p<0.05) in LDH enzyme concentration was detected. Liver enzyme activity i.e. ALT and AST indicated significant differences (p<0.05), indicating higher (p<0.05) values for both the two supplemented groups in comparison with the control ewes group and their lambs.

Response of Lactating Zaraibi Goats to Diets Containing Sesbania sesban Seeds as a New and High Source of Protein.
This work was carried out on dairy goats to investigate the effect of partially replacing CFM protein by Sesbania sesban seeds on milk production, feed conversion efficiency and some blood constituents as well as economic efficiency. Twenty five dairy goats wereIdivided into 5 groups (5 does each). The controlIgroup (G1) was fed a rationIconsisting ofIconcentrate feedImixture and cornIsilage (50:50) accordingIto NRC (1981) recommendation. Sesbania sesban seeds (SS) wereIused toIreplace 10 and 20% of concentrate's protein for groups G2 and G3, respectively. SesbaniaIseeds wereItreated (TSS) by soaking and roastingIand used at theIsame levels (10 and 20%) in G4 and G5, respectively. The feedingItrails lasted for 14 weeks after weaning. The obtainedIresults showed thatIthe daily dryImatter intake tendedIto decrease as a result toIsubstitution of concentrate feedImixture with SesbaniaIseeds in rationsIof dairyIgoats. On the contrary, the daily water consumption as ml/g DM intakeIwas noticeablyIhigher (3.50, 3.64, 3.67 and 3.81) with SesbaniaIseeds rations (G2, G3, G4 and G5, respectively) comparedIwith control (G1, 3.14). The effectIof the testedIrations onIruminal pH values was not significant. Ruminal NH3 concentration post-feeding tended to decrease as a result to using of Sesbania seeds especially G4 and G5. But, ruminalItotal VFA's concentrations post-feeding were significantly with G4 compared with G1 and G3. Moreover, ruminal microbial protein content at 2 and 4 hrs. post-feeding was significantly affected as a result of using of Sesbania seeds in goats rations and the bestIvalue was recordedIwith G4.. The obtained results showed that there is significant effects on some blood parameters ( hemoglobin, MCHC, lymphocyts, platelets count, globulin and enzymatic activites) due to using the tested rations. Concerning milk production, the obtained data indicated that the highest value of daily milk yield was recorded with G4 (1.70 kg) followed by G5 (1.67 kg) then G2 (1.59 kg) and G1 (1.56 kg) while theIlowest value (1.499 kg) was recorded with G3 and the differencesIwere significant. The effectsIof experimental rationsIon milk constituents were not significant. The feed conversion efficiency, based on DM was better with G5 (0.904) then G4 (0.911) followedIby G2 and G3 (0.971 and 1.009, respectively) and lastly G1 (1.015). Therefore, the economic efficiency was improved by 9.25, 10.17, 16.31 and 22.81% with Sesbania seeds rations (G2, G3, G4, and G5, respectively) compared with control (G1). It isIconcluded that partialIreplasment of up to 20% of CFM protein by SesbaniaIseeds has someIpositive effectsIon metabolicIparameters, whichIreflected on the dairyIgoats performance andIeconomicIefficiency.

Comparison between the Effect of Feeding Corn Silage or Berseem as a Basal Diet on: 1- Milk Production and Economic Efficiency of Lactating Friesian Cows.
Twelve lactating Friesian cows with the average body weight of 490-560 kg were used in this study. All animals were in the second to fourth lactation season. Cows were randomly distributed into three similar groups (four for each group) to study the effect of the tested rations on milk production and its composition. All groups were individually fed according to NRC (2001) recommendations. The experimental period lasted for 140 days (20 weeks) after calving. The three experimental rations were formulated nearly as follows: (Control): 40 % concentrate feed mixture (CFM) + 32 % rice straw (RS) + 28 % corn silage (S), (Exp.1): 40 % concentrate feed mixture (CFM) + 32 % rice straw (RS) + 28 % berseem (B) and (Exp.2): 40 % concentrate feed mixture (CFM) + 32 % rice straw (RS) + 14 % corn silage (S) + 14 % berseem (B). The average daily milk yield was the highest (p < 0.05) with group fed exp.1 from W1 to W12 compared with the control ration, while there were no significant effect between exp.1 and exp.2 or exp.2 and control ration. The average milk yield were 12.69, 16.05 and 15.17 Kg/day with feeding on control, exp.1 and exp.2 respectively. The milk composition of protein% was higher (p < 0.05) with feeding on exp.2 (2.51%) than feeding on exp.1 (2.29%), but there was no significant effect between exp.1 and control ration (2.37%) or feeding on exp.2 and control ration. The net energy (NEL Mcal/kg milk) values were significantly (p < 0.05) higher with feeding on control or exp.2 (0.64 and 0.63 Mcal/kg milk respectively) than feeding on exp.1 (0.60 Mcal/kg milk). The protein yield and lactose yield (kg/day) were increased (p < 0.05) with feeding on exp.1 and exp.2 rations than feeding on control ration. The highest values of feed conversion (DMI kg/kg FCM) and net energy of the milk (Mcal/kg milk) were with feeding on rations containing corn silage (control) or corn silage with berseem (exp.2) than ration which containing berseem only (exp.1). The highest values (p<0.05) of feed cost were estimated with exp.1 (40.01 LE) and exp.2 (38.07 LE) than feeding on the control diet (36.09 LE), but there was no significant affect between the control and exp.2 or exp.1 and exp.2. With the same trend the profit (LE) values were higher (p<0.05) with feeding an exp.1 (21.63 LE) or feeding with exp.2 (18.69 LE) than feeding with the control (15.35 LE). Corn silage is an important source of digestible effective fibre and can be an economical source of CP in diets for lactating cows, but increased passage rate with feeding berseem which is more digestible forage NDF might increase efficiency of milk production and composition. So feeding on exp.1 or exp.2 resulted in improving milk production, feed conversion and economic efficiency.
