The present study was designed to investigate the effects of partial replacing green guar (Cyamopsis tetragonoloba) forage (GG) and rice straw or guar forage silage (GS) instead of concentrate feed mixture (CFM) on the digestibility, productive and economic performance and blood biochemical constituents of growing lambs. Twenty four weaned of Farafra male lambs 5 months age and weighed in average 16.69 ± 2.65 kg, were used in a feeding trial for 120 days in a complete block design. Animals were divided according to their live body weight into three experimental groups (8 lambs each), Ration 1 (R1) consists of 60% CFM + 40 % rice straw (control), R2: (40% CFM + 40% GGF + 20 % rice straw and R3: (40% CFM + 40% GFS + 20% rice straw). GGF and GFS were used to cover a partial of protein from CFM. The experimental rations fed according to NRC (1985). Results indicate that the apparent digestibility coefficients of all nutrients and feeding value of rations containing (GG) or (GFS) were better (P<0.05) compared to the control ration. Percentage of apparent N-utilization was currently higher (P<0.05) for the guar green forage and guar forage silage (R2 and R3) rations than the control ration (R1). Significant increased (P<0.05) were reported on total feed intakes, total weight gains, average daily gains (ADG) and better feed conversion ratios (FCR) and economic efficiencies for groups R2 and R3 compared with control group. The realized ADG were 198.08 and 185.83 g/day for R2 and R3, respectively, while lambs of the control recorded 177.11 g/day. No significant differences among experimental diets in serum total protein, albumin, globulin, trans-aminase enzymes (AST and ALT), cholesterol, triiodothyronine (T3) and Thyroxin (T4) hormones. It could be concluded that, feeding guar green forage or guar forage silage up to 40% as partial replacement of concentrate feed mixture for Farafra growing lambs rations were recommended. Such rations resulted in superior nutrition, better daily gain, feed conversion and economic efficiency.

This study was conducted to determine the performance of broilers fed diets supplemented with dry wild mint (Mentha longifolia) and sage (Salvia officinalis) leaves and which are among the alternative growth promoters. A total number of 315 unsexed broilers seven-day old (Ross 308) were randomly allocated to seven treatments with three replicates. The dietary treatments consisted of the basal diet as control (T1), 10 (T2), 20 (T3) and 30 (T4) g/kg wild mint, 10 (T5), 20 (T6) and 30 (T7) g/kg sage added to the basal diet. The results showed birds fed on diet with 20 g/kg wild mint leaf powder significantly had (P≤0.05) the best body weight and FCR as compared to the group fed on 20 and 30 g/kg of sage without any significant effects compared with the other groups. Birds fed on control groups consumed higher (P≤0.05) feed intake compared with the other treatments. Supplemented broiler diets with 20 g/kg wild mint significantly increased slaughter, carcass, gizzard, liver, leg, giblet and total giblet weight compared with chicks fed on diet supplemented with either 20 or 30 g/kg sage without any significant with the rest group. Not significant affected were observed on heart, head, gut and lung weight due to the treatments. Birds fed in diet supplemented with 20 g/kg wild mint had the highest values of net revenue and economic efficiency compared with the control group. Blood biochemical parameters including serum protein, albumin, globulin, A/G ratio, and glucose concentrations were not statistically (P>0.05) influenced among all treatments.

The study conducted at Faculty of poultry farm, Assiut University. Eighty weaned rabbits (40 of Newzealand and California rabbit breeds. 20 males and females of each) to evaluate the blood performance and energy value of meat of rabbits drenched different doses of propolis. Rabbits were allocated to one of the treatment groups (control group, 0.2, 0.4 or, 0.6 g drenched propolis /kg body weight) from 42 to 84 days of age. The results indicated that, the differences in body weight, daily gain and fed conversion ratio were not significant among all groups. RBCs and Hb were increased significantly of males treated with 0.2 g of propolis group than females and other groups. No significant differences were observed in Hb, WBCSs and total Protein due to sex. Total leucocytes counts were decreased by using propolis 0.2 treatment of females and males, also, 0.2 group treated California rabbits had the lowest values compared with 0.6 g of Newzealand rabbits. Total protein had the highest values in females and males blood samples treated with 0.4g propolis. The treatment with 0.2g increased total protein values in California but the 0.4g level increased it in Newzealand ones. Energy values (kJ.100 g -1 ) were higher in females (465.38±3.49 vs. 460.04±2.16 kJ.100 g -1 ), California exceeded New Zealand ones, were not significant. The 0.6g propolis level was the highest one (473.63±2.23) and significant. Correlation between W.H.C and cooking loss was negative and not significant. Both blood performance and energy value formulas are completely panoramic ways to evaluate Rabbits health.
