The present study was performed in order to examine the effect of using marjoram extract as a natural growth promoter on performance and intestinal bacteria of broiler chickens. Marjoram extract was prepared by the maceration method. Then, an in vitro trial was conducted to determine the antibacterial activity of marjoram extract against six bacterial strains. The results of the antibacterial disk diffusion test showed that marjoram extract has a high inhibitory effect against both Gram-positive and Gram-negative bacteria. Later on, an in vivo feeding trial was done using 90 day-old Ross broiler chicks. The chicks were divided into two groups of three replicates each. The first group served as a control without any supplementation while the second group was supplemented with marjoram extract as a growth promoter. The results showed that addition of marjoram extract led to a significant (p<0.05) improvements in final live body weight, total weight gain and total feed intake of broiler chickens. On the other hand, the relative weights of internal organs were not affected by marjoram extract supplementation. The total aerobic intestinal bacteria count of the broilers fed the marjoram extract supplemented diet was significantly lower (p<0.01) than that of the control group. The overall results suggest that marjoram extract could successfully be used as a natural growth promoter alternative to antibiotic in broilers’ diets.

Data on the pre-weaning growth traits of 815 Egyptian native baladi calves borned from the period 1993 to 2014 were used to study the non-genetic, and genetic phenotypic factors of pre-weaning growth traits. The data were collected from Animal Production Research Station at El-Serw, Ministry of Agriculture. Covariance component for birth weight (W0), weaning weight (WW) and average daily gain from birth to weaning (ADG) were estimated by using least squares and maximum likelihood (LSMLMW) computer program of Harvey (1990). Model included sirs and dams within sires as random effects, year and season of birth, sex of calf and parity of cow as fixed effects. In addition, cow weight at calving and suckling days were used as covariate.
The means and standard deviations of body weight at birth, weaning, and average daily gain were 23.47±4.29 kg, 80.59±6.36 kg and 0.477±0.06 g/d, respectively. Statistically season and year of calving and parity of cow did not showed significant effects, but sire and sex of calf had significant effects on studied traits.
The values of heritability were 0.15, 0.33 and 0.38 for body weights at birth, weaning and average daily gain from birth to weaning, respectively. The results showed that most estimates of genetic and phenotypic correlations among body weights and daily gain traits were positive.

A total of 16 healthy Friesian young bulls aged 15 months and averaged 291±15.6 kg live body weight was divided into two equal groups according to their live body weight. Bulls were housed in two different housing systems (tie-stall and loose bran) under the same environmental conditions to evaluate semen quality and some physiological responses during three seasons (winter, spring and summer). Air temperatures (AT, oC), relative humidity (RH %), temperature humidity index (THI), and body temperatures (BT) were recorded twice a day at 08:00 hr and 14:00 hr. Blood samples were collected twice a month to evaluate the hemoglobin content (Hb, mg/dl), hematocrit values (Ht%) and testosterone hormone concentration (ng/dl). Semen was collected from all bulls under the two housing systems twice a week using an artificial vagina to evaluate the semen characteristics and morphology traits. Results showed highly significant effect (P<0.05) of the environmental conditions on bull physiological responses. The animal housing could affect the semen quality; however, it did not affect all the seminal traits which were investigated in this study. The seasonal variation was more effective factor that changing the semen quality than housing system types. Bulls showed better results under loose housing system in all seasons. Summer season where the THI reached 91 had negative effects on semen traits. It could be concluded that animal housing systems and seasonal variations can affect the seminal quality and some physiological parameters of Friesian bulls.

The effect of different levels of sodium chloride (NaCl) on water and feed intakes, milk yield and its composition and some physiological responses in Friesian cows was examined in this study during the three months of summer season (June, July and August). A total of 25 cows averaging 482.4±20.5 kg LBW, ranging 41-76 months of age and 2- 4 parities was used. All cows were at post-partum period after 25 days of calving. The cows were divided equally (five animals) into five groups according to their LBW, parity and its milk production. The 1st group cows were fed a basal diet without any treatment, that were considered as a control group (G1), and the cows in the three groups (G2), (G3) and (G4) were received a daily drinking water containing NaCl as 2000, 5000 and 7000 mg/l, respectively, during the experimental period. While, the 5th group cows (G5) were received drink water containing 2000, 5000 and 7000 mg/l NaCl during the first, the second and the third months of the experiment, respectively. Results showed that rectal temperature values (RT, oC) were significantly (P<0.05) lower in groups G3, G4 and G5 than in groups G1 and G2 in June, July and August, and the lowest value was in group G3 in June month. Values of white skin temperature (oC) and respiration rate were significantly lower in groups G3, G4 and G5 than in groups G1 and G2. And values of black skin temperature (oC) were significantly lower in groups G2, G3 and G5 than in groups G4 and G1. Water intake values of the treatment groups were significantly (P<0.01) higher than the control group as follows 12.3, 30.56, 54.49 and 18.6% in G2, G3, G4 and G5, respectively, where the highest value of the water intake was in group G4. Total dissolved solids (TDS) of SO4, CO3, Cl, Na and Ca were significantly (P<0.01) higher in treated groups than in the control group, TDS were increased with the increased amount of salt in the drinking water. Concentration of total protein, albumin and globulin in blood plasma were not significant. Glucose concentration was higher significantly (P<0.05) in G4 and G5 than the control group. The effect of NaCl treatment in drinking water on daily milk production as actual milk yield, fat corrected milk (FCM) as well as fat and protein yields in G3 and G4 tended to be significantly higher than the control and other treatment groups (G2 and G5). Milk composition was not affected by salt treatments. Cows in groups G3, G4 and G5 showed significantly (P<0.05) lower somatic cell counts (SCC) in milk yield as compared with G1 and G2 groups. Conclusively, the obtained results recommend common salt addition to the drinking water at 5g/L to improve the performance and production in Friesian lactating cows.

This study was carried out to investigate the effect of large particles (zinc Zn or selenium SE ) or nano-Zn and nano-Se particles as feed supplement in lambs rations on feed intake, degradability, growth performance and some blood parameters. Twenty five growing lambs aging about 5-6 months with average body weight of 24.5kg, were used. Lambs were divided into five similar groups and fed randomly on one of the following rations. The first group received the basal ration, composed of concentrate feed mixture (CFM) to cover 50% of protein and energy allowances recommended by NRC (1989) and clover hay (CH) without feed additives which served as the control group (R1). The other tested groups were randomly fed the control ration supplemented with 10 mg large particles zinc (L-Zn), 0.04 mg large particles selenium (L-Se), 5 mg nano particles zinc (N-Zn) and 0.02 mg nano particles selenium (N-Se) / kg CFM for rations R2,R3, R4 and R5, respectively. Two canulated sheep were used to measure in sacco disappearance of DM, OM and CP of tested rations.
Results showed that N-Zn & N-Se particles groups improved DM, OM and CP degradability compared with control group. But there were no significant differences among large particles groups and control group. Ration contained N-Zn had a significant effect on DM intake, but there were no significant differences among the large particles zinc (L-Zn) or selenium (L-Se) groups and control group among DMI. On the meantime, results showed that R4 & R5 groups increased (P<0.05) average daily gain and total weight gain compared to the control group. Also, feed conversation as DMI/ kg gain for R4 & R5 groups were improved by 16.93 and 18.25%, as compared with control group. Feed cost /kg gain was decreased for R4 and R5 groups as compared with control group. Serum total protein and albumin for R4 was increased compared with control group. While no significant differences between control group and other groups were found among AST and ALT values.
In conclusion, large size particles of Zn or Se could be replaced with smaller amount of nano particles Zn or Se without any side effects on the animal performance.
