This study was conducted to investigate the effect of replacing soybean meal (SBM) by locally available oilseed meals i.e., sunflower seed meal (SFM) and sesame seed meal (SSM) at different substitution levels 25, 50 and 100% on an isonitrogenous and isocaloric basis. A total number of 315 mixed sex 7th days -old Japanese quails were randomly distributed into 7 treatment groups of 45 birds each, with three replicates containing 15 birds each. The experiment was carried out for 42 days (from7th to 48th days of age). Treatment 1 was fed a control diet (100% SBM), whereas treatment 2, 3,4,5,6 and 7 were fed diets containing 25, 50 and 100% of both SFM and SSM respectively. SBM was replaced with SFM and SSM on a weight basis. Experimental diets and fresh water were offered ad libitum along with the experimental period. Results revealed that substitution of SBM by SFM at 50% and 100% significantly (p≤0.05) increased live body weight, body weight gain, protein and energy efficiency ratios compared with quails fed other dietary treatment groups. While feed intake, protein and energy intakes were significantly (p≤0.05) higher for quails fed 100% SBM (control group) compared with quails fed SFM or SSM at different levels. However feed conversion ratio was the best for quails fed 100% and 50% SFM, followed by quails fed 100%SSM, 25%SFM, 50% SSM and control diet (100% SBM) respectively, while the worst FCR was observed for quails fed 25% SSM. The highest mortality rate was observed for quails fed 100% SSM, while the lowest values were recorded for quails fed 25% SFM. Carcass traits expressed as percentage of body weight were significantly (p≤0.05) affected by replacing SBM with SFM and SSM at different levels, where the percentage of total edible part were significantly (p≤0.05) higher for quails fed 50 % SFM, while the lowest values were shown for quails fed 25% SSM and 100% SBM (control group). However total inedible parts percentage were significantly (p≤0.05) higher for quails fed 100% SBM (control group), while the lowest values were recorded for quails fed 50% SFM. Concerning plasma parameters and carcass composition measured at the end of experimental period significant (p≤0.05) differences were observed among the experimental groups due to feeding Japanese quails on diets containing different levels of SFM and SSM or control group, except with ALT values, where insignificant differences were detected. Replacement of SBM by SFM or SSM at 25, 50 and 100% levels reduced feed costs/birds. In general, conclusion based on the present results it could be recommended that SFM or SSM can safely replace SBM up to 50 and100% without any adverse effects on growth performance or carcass traits of Japanese quail and using of SFM in quail diets as a plant protein alternative source was better than SSM.

A total number of 42 male New Zealand white (NZW) rabbits at the age of 14 weeks were randomly divided into seven experimental groups (6 male for each) to study the effect of adding dried onion ( DO) and garlic (DG) on nutrients digestibility , caecotrophy and caecum activity. Rabbits were fed a basal diet supplemented with different levels of DO and DG as follows: 1) control group (CG), 2) CG+1 % DO, 3) CG+1.5 % DO, 4) CG+1% DG, 5) CG+1.5 % DG, 6) CG +0.5 % DO+0.5% DG, 7) CG +0.75% DO +0.75 % DG, respectively. All diets were formulated to be iso-nitrogenous and iso-caloric. The obtained data showed that dry matter intake did not significantly differ among dietary treatments as well as it was similar for collared rabbits compared with those uncollared. The CP digestibility coefficient was significantly (p<0.05) higher for rabbits fed diets included 1.5 % DG, 1.5 % DO, 0.5 % DO+ 0.5% DG and 1 % DG than those fed either control diet or other groups. Rabbits fed 0.5% Do + 0.5% DG diet recorded significantly higher CF digestibility (P<0.05) than the other treated groups. The nutritive values expressed as TDN%, DE and ME Kcal/Kg DM of diet supplemented with 0.5% DO +0.5% DG were significantly (p<0.05) higher than those fed 1% Do. The DCP% for 1.5% DO, 1% DG, 1.5%DG and 0.5% DO+0.5% DG diets was significantly (p<0.05) higher than 1% DO, 0.75% DO+0.75%DG and control groups. The digestibility coefficients of all nutrients as well as nutritive values of tested diets were similar between uncollared and collared groups .Treatment groups showed significant (p<0.05) increase in Bacterial total count compared with the control group.

A 35-d trial was conducted to study the effect of phytogenic additives on growth performance and cecal bacterial populations of broilers. The feeding program consisted of a starter diet until 21-d and a grower diet until 35-d. There were 4 treatment groups: control, 50g EO (essential oil)/ ton, 100g EO/ton and 150g EO/ton. Slight non significant improvements have been observed for body weight, weight gain, feed intake and feed conversion ratio in the starter stage when birds fed diets contained 50g EO/ton. In both grower stage and through out the entire period of growth study no differences in growth parameters have been observed when birds fed diets contained 100g EO/ton and those fed the control diet. The worst performance has been observed by the birds fed diets contained 150 EO/ton through the whole stages. Yet, in general, there were no significant difference in growth performance between birds fed the control diet and those fed diets supplemented with EO. No mortality occurred during the whole period of the growth study. Using a commercial blend from thymol and trans-cinnamaldehyde revealed a disparate impact on cecal microflora population. Yet, this was not reflected on the bird growth performance. This may be referred to the balanced diet and controlled condition under which the trial was conducted. The present data suggest, further investigation should focus on the mechanism of EO, the ratio between components of the blend and their effect on bird performance under uncontrolled conditions such as (heat stress, unbalanced diet …..etc.) by increasing levels of EO.

Forty eight Friesian calves averaged 234.4±1.23 kg live body weight were assigned to investigate the effect of using sorghum or alfalfa alone or/and intercropped legume-grasses mixtures in daily rations of growing Frisian calves on nutrient digestibility , nutritive values , some blood parameters , daily gain and feed conversion. Friesian calves were divided into four similar experimental groups according to body weight. The experiment included two stages. The first stage represented a growing period (140 days), during which the calves were fed on the following rations: 1- The control group was fed 60% concentrate feed mixture + 40% rice straw. 2- The first tested group was fed 30% concentrate feed mixture + 60% Alfalfa + 10% rice straw. 3- The second tested group was fed 30% concentrate feed mixture + 60% sorghum + 10% rice straw. 4- The third tested group was fed 30% concentrate feed mixture + 30% Alfalfa + 30% sorghum + 10% rice straw. During the second stage ( the finishing period,80 days) the corresponding calves were fed 60% concentrate feed mixture (CFM) + 40%rice straw for all experimental groups. Results showed that the digestibility of DM, OM and CF of R1 (control ration), R2 (contained 60 % alfalfa) and R4 (contained 30% alfalfa plus 30% sorghum forage) were significantly (P<0.05) higher than those of R3 (contained 60% sorghum forage). While the nutritive values as TDN% and DCP% were significantly higher (P<0.05) for R1 (control ration) than those of R2 (contained 60 % alfalfa), R3 (contained 60% sorghum forage) and R4 (contained 30% alfalfa plus 30% sorghum forage). The average daily feed intake by calves fed alfalfa (R2) during growing period were higher than those fed R1 (control ration) , R3 (contained sorghum forage) and R4 (contained alfalfa plus sorghum forage). Average daily feed intakes during the finishing period showed that calves fed R1 (control ration) and R4 had the highest DM intake. However those fed ration R2 (control ration) showed the lowest intake of DM intake. Final body weight , total and daily body weight gain of calves fed R1 (control ration) were375.42,141.67 and 1.01 kg ,respectively during growing period, showing significantly higher (P<0.05) than other different ration , but final body weight , total and daily body weight gain of calves fed R3 (contained sorghum forage) recorded 342.42,105.42 and 0.75 kg , respectively. It were significantly lower (P<0.05) than other different rations. While final body weight, total and daily body weight of calves fed R4 (contained alfalfa plus sorghum forage) were significantly (P<0.05) higher than R2 (contained alfalfa) and R3 (contained sorghum forage). The best feed conversion was attained for the group feed R1 (control ration) 8.61, 5.68 and 0.96 for DM, TDN and DCP, respectively followed by group fed R4 (contained alfalfa plus sorghum forage) being, 13.56, 8.95 and 1.50 for DM, TDN and DCP, respectively during growing period. It could be concluded that the alfalfa–sorghum mixture was better than alfalfa or sorghum as green forage in growing calves feeding in the summer season which lead to improve digestibility of most nutrients, increase daily gain and feed conversion .Moreover, using sorghum grass tended to give better daily gain and higher economical return during the whole fattening period.

Sixty four buffalo calves averaged 307.4 ± 10.99 kg live body weight were assigned to evaluate the effect of supplementing rations of buffalo calves with yeast culture and enzyme on nutrient digestibility, nutritive values, some blood parameters, daily gain and feed conversion. Buffalo calves were divided into four similar experimental groups and fed the same basal ration but differed in feed additives. Calves in the 1st group were fed a basal ration containing 40% concentrate fed mixture, 40% corn silage and 20% rice straw without additives (control). Calves in the 2nd and 3rd groups were fed the same basal ration supplemented with either 10 g enzyme/ head /day (Fibrozyme containing 100XU/g xylanase) or 10 g yeast culture/ head /day (Yea-Sacc containing 108 cells of Saccharomyces cerevesiae/g), respectively. While those of the 4th group, were fed the same basal ration supplemented with (5g yeast + 5g Enzyme)/ head /day. Feeding period lasted for 116 days. At the end of the feeding trials, four digestibility trials using 12 buffalo calves, three in each trial, were conducted to determine nutrients digestibility coefficients and feeding values of the four experimental rations. Blood parameters, feed utilization and economic efficiency were also studied. Results showed that calves fed rations supplemented with both 10g yeast , 10g Enzyme and 5g yeast plus 5g Enzyme improved (P<0.05) most nutrients digestibilities and feeding values as TDN compared with control ration, as well as blood parameters. Daily gain , feed conversion and economic efficiency were the highest (P<0.05) for calves fed ration supplemented with 5g yeast plus 5g Enzyme (R4) being 1.19,10.30 and 1.87, respectively .It could be concluded that animals fed ration supplemented with feed additives attained to have higher daily gain, reduced feed cost and improved of feed and economical efficiency . Moreover, animals fed ration supplemented with enzyme plus yeast culture recorded the highest performance followed by those fed yeast culture or enzyme supplemented rations alone.

This work was carried out on ewes and born kids to investigate the effect of feeding concentrate feed mixtures supplemented with dried Yeast or Matricaria chamomile on body weight changes, nutrients digestibility's, nutritive values of tested diets and growth performance of growing lambs. Some rumen fermentation parameters and blood constituents as well as economical efficiency were studied.
Forty pregnant crossbred ewes (l/2 Fin. X l/2 Rahmani) at late pregnancy (2 months before lambing) with an average body weight of 53.50 + 0.84 Kg and age of 2 years were used in this study.
Ewes were distributed into four similar groups (10 ewes each group) and were randomly fed the four experimental rations as follows:
Ration (T1): Consisted of concentrate feed mixture (control).
Ration (T2): Consisted of concentrate feed mixture supplemented with 50 mg dried yeast/Kg L.B.W/day.
Ration (T3): Consisted of concentrate feed mixture supplemented with 50 mg Matricaria chamomile (M.C)/Kg L.B.W/day.
Ration (T4): Consisted of concentrate feed mixture supplemented with 100 mg Matricala chamomile (M.C)/Kg L.B.W/day.
Wheat straw was offered at 1 % from live body weight as a sole source of roughage for all groups.
After lambing, newly born male and female lambs were taken to study growth performance (12 lambs from each group, 6 males and 6 females) with an average live body weight of 19-20 Kg and were fed the same rations of their dams.
Results obtained revealed that using dry yeast or chamomile as feed additive for growing lambs lead to increase most nutrients digestibility compared to the control ration. Moreover, feeding value expressed as TDN and DCP appeared to be higher (p < 0.05) with tested rations, being 52.63, 56.03, 55.17 and 56.26 % TDN for rations T1, T2, T3 and T4, respectively. Corresponding values of DCP % were 10.55, 11.79, 10.66 and 11.51 %, respectively.
Average daily gains of lambs were 122. 30, 140.82, 140.38 and 127g/day for animals fed T1, T2, T3 and T4, respectively. Animals fed tested rations gained 15.14, 14.78 and 4.62 on advantage with rations T2, T3 and T4, respectively.
Feed efficiency expressed as Kg TDN/Kg gain were 5.64, 5.09, 5.40 and 5.78 Kg TDN/Kg gain for animals fed rations T1, T2, T3 and T4, respectively, being the best for the group fed ration T2 ( supplemented with dry yeast ).
The results also showed that the average of feed cost to produce 1 Kg live body weight were 6.18, 5.50, 5.44, and 6.08 Egyptian Pounds, for groups fed rations T1, T2, T3 and T4, respectively. Consequently, ration T3 attained the cheapest cost to give one Kg gain. The Economic efficiency improved by 20.25, 22.78 and 3.16% for groups fed ration T2, T3, and T4 respectively compared with group fed the control ration.
Results showed that feeding tested rations containing either dry yeast or chamomile were affected fermentation in the rumen. Animals fed ration T2 containing dry yeast attained lower pH value and the highest ammonia-N and total VFA’s concentration, while those fed chamomile treatment recorded lower ammonia-N and total VFA’s concentration than that fed control ration.
It was also observed that, blood profile was affected by the lasted feed additives. So, total protein and albumin increased with supplemented ration with either dry yeast or chamomile, showing the highest concentration with blood of animals fed ration T4. The same significant trend was observed with other measurements such as glucose, AST and ALT concentrations, while total lipids and cholesterol concentrations tended to be lower with animals fed tested rations, except for those fed T2 with total lipids. Also, it was noticed that the different stages of sampling affected on blood parameters.
Generally, it could be concluded that, using dry yeast and chamomile as feed additives in rations of growing lambs lead to increase most of nutrients digestibility, feeding value and attained higher daily gain. Moreover, the feed additive improved feed efficiency and decreased feed cost per Kg gain with no side effect on ruminal activities and blood parameters.

A factorial experiment (3×2) was conducted to investigate the influence of feeding diets containing three crude fiber levels (12.52, 14.51 and 16.51%) with or without (0.0 or 0.03%) a probiotic supplementation on performance, nutrient digestibility, carcass traits and blood constituents of growing New Zealand White (NZW) rabbits. A total of 72, six-week-old NZW rabbits were individually weighed, randomly divided into 6 equal experimental groups, each with four equal replications, and kept at battery cages in a naturally-ventilated house. All groups of rabbits were reared under similar hygienic and managerial conditions. Six experimental diets were formulated and used during the experimental period from 6 to 12 weeks of age. Performance were evaluated in terms of live body weight, daily weight gain, daily feed intake, feed conversion ratio, protein efficiency ratio, efficiency of energy utilization and performance index. Digestibility of nutrients [dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), crude fiber (CF) and nitrogen-free extract (NFE)], carcass traits (relative weights of carcass, total edible parts and abdominal fat) lengths stomach, caecum and small and large intestines, and some blood plasma constituents (glucose, cholesterol, triglycerides, total protein, albumin and globulin) were also determined. The results obtained can be summarized as follows: Growth performance, carcass traits and lengths of alimentary tract segments, blood constituents were not significantly affected by dietary crude fiber level or probiotic supplementation. Increasing dietary crude fiber level from 12.5% to 14.5 or 16.5% decreased the digestibility of DM, OM and NFE but significantly improved CF digestibility for 12-week-old NZW rabbits, while the digestibility of CP and EE was not affected. Dietary supplementation with probiotic had no significant effect on the digestibility of nutrients, with the exception of a significant improvement in CP digestibility compared with that of the control rabbits. The interactions between dietary fiber level and probiotic supplementation were not significant for all criteria examined in the present study. Based on the obtained results, it is concluded that the optimal level of dietary crude fiber for fattening rabbits to achieve maximal growth rate and best efficiency of feed utilization is 12.5%.

The present work was carried out to study the effect of using dried distillers grains with soluble (DDGS) as a source of protein in ration formulation of buffalo calves. DDGS was included in concentrate feed mixture (CFM) at 0, 11, 16, 21 and 27% to cover 0, 20, 30, 40 and 50% of total protein, respectively.
Fifty male buffalo calves averaging 320.16 kg live body weight were randomly distributed into five similar groups (10 in each) and assigned to receive five concentrate feed mixtures containing five levels of DDGS. Animals were fed CFM along with berseem hay and wheat straw at the ratios of 70: 20: 10, respectively. The feeding trail lasted 184 days, during which, five digestibility trials were carried out to determine the digestibility and feeding values of the experimental rations. In addition, samples of rumen liquor and blood serum were taken to determine some ruminal and blood parameters. Also, feed and economical efficiencies were studied.
The results showed that:
1- Digestibility coefficients were significantly (P<0.05) higher in DM, OM, CP and CF with animals fed rations containing DDGS. Nutritive values expressed as TDN (%), DCP (%) and DE (Mcal/Kg DM) were significantly higher (P<0.05) for ration E (containing 27% DDGS) than the other rations.
2- Animals fed ration E (containing 27% DDGS) showed the highest TDN (77.03%) DCP (12.49%) and DE (3.40 Mcal/Kg DM) versus 65.67%, 11.00% and 2.89 Mcal/Kg DM for animals fed control ration. However, all experimental rations (containing DDGS) appeared to higher nutritive values than that of control ration.
3- The highest daily gain (1.170 Kg) was recorded with animals given ration E, which had 31.46% extra improvement and increase in weight gain. Also, animals fed experimental rations (B, C, D and E rations) tended to have better feed efficiency, showing the best feed utilization efficiency expressed as DM, TDN or DCP per Kg gain being 11.147, 8.586 and 1.392 Kg/Kg gain, respectively, for animals fed ration E.
4- Animals fed ration E (containing 27% DDGS) appeared to have the lowest feed cost/Kg weight gain (17.837 LE).The highest economical efficiency (1.233) versus the highest feed cost and lowest economical efficiency was observed with animals fed control ration (ration A).
5- All ruminal and blood serum parameters were within the normal values, showing that added DDGS in ration formulation of fattening buffalo calves had no adverse effects on serum parameters and led to get better performance of animals.
Generally, it may be concluded that, the inclusion DDGS at 27% to cover 50% of total protein of concentrate feed mixture in fattening buffalo calves rations tended to produce better nutrient digestibility and feeding values. Moreover, animals fed rations containing DDGS had higher weight gains and lower feed cost with the best economical efficiency without any adverse effects on ruminal or blood serum parameters.
