This study aimed to use dried distillers grains with solubles (DDGS) as a replacement of yellow corn in sheep rations. The trial was carried out at Animal House of Animal Production Research Institute; Agriculture Research Center, Egypt. Laboratory evaluation of seven concentrate feed mixtures (CFM) containingDDGS at the rates of 0, 5, 10, 15, 20, 25 and 30% was carried out. Rations with 10, 20 and 30% DDGS as the best dry matter (DMD) and organic matter digestibility (OMD) were chosen to be used in total mixed rations and were compared with control ration in digestibility and feeding trials.
Twenty-four Rahmany lambs averaging 22.79 kg live body weight (LBW) were chosen and randomly divided into four similar groups (6 in each) and assigned to receive four experimental rations (A,B,C and D rations) containing CFM with rate of 0, 10, 20 and 30% DDGS respectively. Additionally, berseem hay (BH) and rice straw (RS) beside CFM were offered to all animals during the trial at therate of 25: 25: 50, respectively.
The feeding trial lasted 150 days. Body weight changes and feed intake were recorded as well as feed and economical efficiencies were estimated. Also, four digestibility trials were carried out to determine the digestibility and nutritive values of the experimental rations. Samples of rumen liquer and blood serum were taken to measure some rumen and blood parameters.
The results showed that:
1- The chemical composition of experimental rations containing different levels of DDGS was almost similar in DM, OM and NFE. It showed somewhat higher in CP and EE% and lower CF% with increasing DDGS levels.
2- Increasing DDGS level up to 30% significantly (P<0.05) increased DM, OM, CP, EE, CF and NFE digestibilities, while increasing DDGS from 10 to 20% appeared to have higher nutrient digestibility with no significant differences, except for NFE digestibility.
3- All experimental rations containing DDGS (rations B, C and D) have higher nutritive values compared with control ration (ration A). Ration D containing 30% DDGS had thethe highest (P<0.05) values for TDN (64.15%) and DCP (9.36%) while there were no significances in the DE (2.83 MCal/ Kg DM) was not significant.
4- Averages daily gains were 109, 116, 124 and 137 gm/day for animals fed rations A,B, C and D, respectively, showing highly significantly (P<0.05) higher gains for lambs given ration D. Increasing DDGS levels from 10 to 20% increased LBW gains with no significant differences. However, the improvements in daily gains were 6.42, 13.76 and 25.69% with rations B,C and D, respectively.
5- Feed utilization efficiency expressed as kg DM or TDN per Kg gain was significantly (P<0.05) higher with ration D containing 30% DDGS, while increasing DDGS from 10 to 20% improved feed efficiency, but not significantly. However, increasing DDGS levels in experimental rations had no significant effecton utilization efficiency of DCP. Moreover, animals fed ration D (containing 30% DDGS) gave the highest gross margin, revenue and economical efficiency with the lowest feed cost per kg weight gain.
6- Animals fed rations containing DDGS (rations B, C and D) showed normal values of rumen and blood parameters with no adverse effects on animal performance.
Generally, it may be concluded that inclusion DDGS in the rations of growing lambs at the rate of 30% tended to increase all nutrient digestibilities and nutritive values. Moreover, lambs fed ration containing 30% DDGS had higher weight gain, better fed utilization efficiency and lowest feed cost. The highest gross margin and revenue were recorded for the 30% DDGS rations with no adverse effect on ruminal and blood parameters.

This study was carried out to determine the effects of using different levels of Guar korma meal (*GK) onmilk yield and milk composition, rumen function of experimental rations fed to sheep and dairy cows. Animals were fed one of from experimental rations, control ration with 0% GK or rations with 5%, 10% and 15% GK. Animals fed rations containing guar korma showed linear decrease (P < 0.05) of total dry matter intake (DMI) with increasing ration guar korma meal level inclusion in rations. Twelve Barki male sheep were assigned randomly into 4 similar groups of 3 animals each to determine the digestibility coefficients, nitrogen balance and nutritive values of experimental rations. Results of digestibility trails showed that there were no significant differences (P< 0.05) in digestibility of DM, OM and CP for ration containing 10% GK compared to the control ration. While, there was significant (P < 0.05) decrease rations containing 5%, 15% guar korma. Similar trend recorded for the nutritive values. However, nitrogen utilization showed positive nitrogen balance with all animals fed the experimental rations. Three cannulated female Barki sheep were used to determined rumen fermentation parameters. The main results showed no significant differences among experimental groups in the values of ruminal pH and NH3-N concentrations, while the highest (P < 0.05) of TVFA'S concentrates were observed with the ration containing 10%GK and the control ration than rations containing 5%,15% guar korma. Dry matter and CP degradability showed significant (P < 0.05) increased for rations containing GK than the control ration. Eight lactating crossbred Friesian cows were used to determine milk yield and milk composition. Cows fed ration containing 5% GK showed slight improvement in milk yield in comparison with the control ration. However Milk fat (%) increased (P < 0.05) for rations containing guar meals compared with the control ration.

Twenty Finn-Ossimi crossbred male lambs with an average live body weight (14.50 Kg) were randomly assigned into five nutritional groups (each of 4 animals) to receive one of five complete mixed rations containing different percentages of dried bakery by-products (DBP) instead of ground yellow corn as unconventional energetic source. Experimental animals were allotted to one of the following rations in a fattening trial for 124 days; R1 : yellow corn 50% and 0 % bakery by-products (control ration), R2 : yellow corn 37.5 % and 12.5% DBP, R3 : yellow corn 25% and 25% DBP, R4 : yellow corn 12.5% and 37.5% DBP and R5 : yellow corn 0% and 50% DBP. A digestibility and nitrogen balance trial were conducted to evaluate the nutritive values of the experimental rations. The effects of these rations on males fattening performance, rumen fluid parameters and economic efficiency were also investigated.
Results obtained showed that:
1- Unconventional energetic sources showed higher (P<0.05) effect on most of digestibilities coefficients of nutrients.
2- No significant differences in dry matter intake were observed, however, R3 recorded the higher intake value (1250 g/h/d) followed by R2 (1190 g/h/d), respectively.
3- R5 (100 % DBP substitute) showed higher (P<0.05) TDN % and DCP % values followed by R3 and R4, respectively.
4- Dried bakery by-products indicated similar positive effects on improving live body weight gain of the experimental animals, and without significant differences among them.
5- Ruminal pH, NH3-N and TVFA’s concentration had in general the normal distribution curve, since they increased at 3 hrs after feeding then decreased at 6 hrs later.
6- Dried bakery by products showed (P<0.05) effects on pH, NH3-N and TVFA᾿s concentrations in ruminal fluid. However, the control ration in general showed lower NH3-N and TVFA᾿s concentrations in comparison with the other experimental rations. On the contrary, the control ration recorded relatively higher pH value in compare with the other tested rations.
7- R4, (37.5 % DBP) was the most efficient feed utilization group among the different DBP groups, while R5, (50 % DBP) was the most economic one.
8- On the contrary, the control group was the most efficient feed utilization group in different feed terms.

The present study was carried out to investigate the effect of dietary inclusion of dried garlic and thyme on productive performance, carcass traits and some blood parameters of growing Japanese quail. Two experiments were conducted simultaneously. In each experiment, three hundreds, two-week-old, unsexed Japanese quail were randomly divided into five experimental groups, each with three equal replications. Ten experimental diets were formulated to contain graded levels of dried garlic (0.0, 1.0, 2.0, 3.0 and 4.0%) or dried thyme (0.0, 0.5, 1.0, 1.5 and 2.0%) and used in experiments 1 and 2, respectively. All quail were fed their respective experimental diets and managed similarly from 2 to 6 weeks of age. Growth performance of Japanese quail were evaluated as feed intake (FI), live body weight (LBW), body weight gain (BWG), feed conversion ratio (FCR) and economic efficiency of production (EEP). At 6 weeks of age, some carcass traits and certain blood plasma parameters of quail were also estimated. The results obtained could be summarized as follows: In experiment 1, quail fed the garlic-containing diets attained significantly heavier final LBW and better FCR; but FI and carcass traits were not affected, compared with their control counterparts. Feeding the garlic-containing diets up to 2.0% positively affected EEP compared with the control group. In addition, feeding the garlic-containing diets led to significant reductions in blood plasma levels of glucose, triglycerides, total cholesterol and low density lipoprotein-cholesterol (LDL-C), and activity of aspartate aminotransferase (AST) while level of high density lipoprotein-cholesterol (HDL-C) was significantly increased; but activity of alanine aminotransferase was not affected, compared with the control group. Quail fed diets containing 2.0 and 3.0% dried garlic showed significantly higher levels of plasma total protein and albumin compared with those of the control birds. In experiment 2, quail fed thyme-containing diets gave superior means of final LBW, FCR and in EEP (up to 1.5% of DT), but FI and carcass traits were not affected compared with their control group. Blood plasma levels of glucose, triglycerides, total cholesterol and LDL-C, and activity of AST were significantly decreased, while levels of total protein, albumin and HDL-C were increased but activity of alanine aminotransferase was not affected, due to feeding the thyme-containing diets compared with the control group. In conclusion, taking the economical aspect into account, the obtained results indicate that dietary supplementation with dried garlic (up to 2%) and dried thyme (up to 1.5%) can exert a beneficial effect on the performance of Japanese quail under the conditions of the present study.

To evaluate the effect of some metabolic mediators such as insulin or/and L-carnitine on milk yield, reproductive performance of premi- (P1) and multi-parous (P2) cows during postpartum (PP), 40 Friesian cows (20 P1 and 20 P2) were divided into 4 similar groups (10 animals in each, 5 P1 and 5 P2). Animals in the 1st group (T1) were considered as a control, while those in the 2nd group (T2) were weekly i.m. injected with 40 IU insulin/100 kg LBW. Animals in the 3rd group (T3) were weekly administrated with oral dose of 1 g L-carnitine (LC)/100 kg LBW, while those in the 4th group (T4) were administrated with an i.m injection of 40 IU insulin plus oral dose of 1 g LC/100 kg LBW. All treatments were within 7-10 days after calving up to first service. All animals were kept under the same management and feeding system. All cows were milked twice daily by milking machine. Milk yield was weekly recorded and milk composition was monthly determined for 4 month-lactation. Animals in heat 40-45 days postpartum were artificially inseminated and pregnancy diagnosis was carried out 45 d post-service. Blood samples were collected at 0, 1, 2, 3 wk of treatment, estrus and pregnancy for progesterone (P4) assay in blood serum. Different reproductive measurements were recorded for 4 month-PP. The obtained data showed that average weekly milk yield (AWMY) was higher (P<0.05) in T4 than in T1, but did not differ from that in T2 and T3 only during the 2nd month of lactation. T2 and T3 insignificantly increased AWMY as compared to T1. Average daily milk yield (ADMY) or total milk yield (TMY) increased (P<0.05) in T2, T3 and T4 by about 13, 14 and 15% as compared toT1, respectively. AWMY, ADMY and TMY were not affected by parity. Milk composition was not affected by treatment at different lactation months. Percentages of protein, solids not fat and total solids in milk only during the 2nd month of lactation were higher (P<0.05) in P2 than in P1. Average interval from treatment to estrus (ITE) or to conception (ITC) and number of doses required for conception were the shortest inT3. T2 and T4 showed nearly similar values. T3 showed shorter (P<0.05) postpartum first estrus (PPFEI) and service (PPFSI) intervals than T1 (58.9 and 65.2 vs. 86.9 and 95.3 d, respectively). T3 showed high (P<0.05) conception rate (CR, 78%), least number of services per conception (NSC, 1.33), lowest days open (DO, 81.4 d) and the shortest calving interval (CT, 368 d), while T4 showed the highest (P<0.05) CR (90%). ITE, NTC, ITC, PPFEI, PPFSI, DO and CI were lower (P<0.05), while NSC and CR was greater (P<0.05) in P2 than in P1. Serum P4 concentration at 0, 1, 2 and 3 wk of treatment, 1st estrus, and estrus of conception was not affected by treatment. Only, serum P4 concentration at pregnancy was higher (P<0.05) in T4 than in T2 and T3, but did not differ from that in T1. Serum P4 concentration was higher (P<0.05) in P2 than in P1 only at estrus of conception and pregnancy.In conclusion, administration with an i.m injection of 40 IU insulin plus oral dose of 1 g LC/100 kg LBW during early postpartum period may consider successful treatment for improving milk yield and reproductive performance of lactating Friesian cows (primi- and multi-parous) under the experimental conditions.
