Rabbits were classified into four equal groups (G 1-G 4). The 1 st and 3 rd groups received basal ration with 100 % and 90 % energy requirement and served as first and second control respectively. The 2 nd and the 4 th groups received basal ration with 100 % and 90 % energy requirement supplemented with mixture at the level of 1.5 %, respectively. The results showed that decreasing energy requirements level by 10% in rabbit diets significantly (P<0.05) increased the digestibility coefficients of DM, OM, CP and NFE & DCP values. The 90% energy level insignificant increased (P>0.05) CF and EE digestibility coefficients and TDN value. The 90% energy requirement with 1.5 % additives mixture (G 4) recorded the best digestibility coefficients of DM, OM, CP, CF, EE, NFE and nutritive values of TDN and DCP. The 90% energy level significantly (P<0.05) improved feed conversion (g intake /g gain) of DM, CP, DCP, TDN and DE, respectively compared to control. Adding mixture at 1.5 % level significantly (P<0.05) improved feed conversion (g intake /g gain) of DM, CP, DCP, TDN and DE, respectively compared to control. The 90% energy with 1.5% additives mixture (G 4) recorded the best values of final body weight, body weight gain, and average daily gain as well as feed conversion. Additives mixture at 1.5% level significantly (P>0.05) increased the total inedible offal's (weight and % of SW) and Dm contents of the 9, 10 and 11 th ribs. The 90% energy level with 1.5% additives mixture (G 4) diet recorded the highest value of relative economic efficiency (145.1%) and the lowest value of feed cost/ kg live body weight (3.97 LE). It can be concluded that this mixture of medicinal plants can be considered as growth promoter that is effective for improving the utilization of low energy diet by lowering circulating glucose levels through enhancing insulin sensitivity.

Twenty Farafra male lambs weighed on average 41.39 ± 1.66 kg were divided randomly into four similar groups of 5 animals each. All groups were fed on concentrate feed mixture (CFM) at 3% of their body weight, and wheat straw fed ad lib. to replace 100% of the soybean meal (SBM) as a source of protein, black cumin seed meal (BCSM), cottonseed meal (CSM) and sesame seed meal (SSM) were incorporated into the CFM. The feeding trial extended for 66 days followed by digestibility and nitrogen (N) balance trials. Results The results indicated no difference in total feed intake between experimental groups. Digestibility of crude protein, ether extract and crude fiber for animals fed CSM ration was higher ( p < 0.05) than those fed the other rations. On the o...

Intake and utilization of it can be increase by applying some treatments; physical, chemical, and biological methods, biological method shows the most effective method. This study aimed to evaluate the effect of replacing clover hay (it is high quality roughage in Egypt and high price) by fungal treated corn stalks with Trichoderma ressei on carcass characteristics and meat analysis of rabbits. Forty-two weaned New Zealand white rabbits were divided to two groups. The first group (24 rabbits) was divided into 4 subgroups (6 each), and were fed diets contained 0% corn stalks (control), 33, 66, and 100% treated corn stalks with media only (without Trichoderma ressei). The second group (18 rabbits) was divided into 3 subgroups (6 each), and were fed diets contained 33, 66, and 100% fungal treated corn stalks with Trichoderma ressei as replaced of clover hay (11, 22, and 33% of whole), each group was divided into 3 replicates (2 each). At the end of the trial, 3 rabbits from each group were slaughtered to derermine carcass characteristics and chemical composition of meat. Results: There were no significant differences in values of dressing percentages either between treatments or levels. Also, the interaction between treatments and levels were no significant. Feeding fungal treated corn stalks did not significant effect on dry matter (DM), crude protein (CP), and ether extract (EE), while significant(P < 0.05) increased ash content compared with without Trichoderma reesei. And feeding 100% corn stalks recorded (P < 0.05) the highest value compared with levels 33 and 66%. The interaction between treatments and levels on CP, EE, and ash was significant, the results pointed that fed level of 66% treated corn stalks was significant (P < 0.05) increased CP content compared with 66% without Trichoderma reesei. Also fed level of 100% treated corn stalks was recorded (P < 0.05) the highest value of ash content compared with level of 66% treated CS and with levels of 33, 66, and 100% without Trichoderma reesei, respectively. While fed treated corn stalks at 66% significant (P < 0.05) decreased EE content compared with feeding level of 66% without Trichoderma reesei. But, there were no significant difference in DM content. It could be concluded that treated corn stalks with fungi could be used without any adverse effects and enhance carcass characteristics and chemical composition of rabbits meat.

Method Forty-five New Zealand White (NZW) rabbits aged 5–6 weeks (730 ± 23 g) were divided into five groups (9 rabbit in each group) for 72 days. The first experimental ration considered the control (R1) that not contained apricot seed kernel (0% ASK). The 2nd, 3rd, 4th, and 5th experimental rations contained 0.75, 1.5, 3, and 4.5 % for R2, R3, R4, and R5, respectively. Results ASK had no significant effect on the nutrient digestibility except for EE and nutritive values. Incorporating ASK at different levels significantly (P < 0.05) increased average daily gain (ADG) and feed conversion ASK at different levels had no effect on both digestive tract and head weights, while giblets and carcass weights were i...
