Thirty Egyptian healthy female buffalo cows were used in this study. The experimental animals were divided into two similar groups (15 in each group). control (G1, non-cooling) and cooling group (G2). Each group was divided into three sub-groups (5 in each),control, supplemented with zinc methionine or niacin.Source of cooling water was the main concrete tank of the farm where temperature of the water ranged between 19-21 C0 at time of cooling. Results show that skin and rectal temperature degrees, and respiration rate decreased under cooling system. Cooling system decreased (P<0.05) haemoglobin concentration and packed cell volume (PCV %), while the effect of feed supplements was not significant. Zinc and Niacin supplements increased (P<0.05) total protein concentration in blood plasma only under cooling system. Albumin and glucose concentrations in blood plasma were not significantly effected. Blood urea nitrogen concentration in blood plasma decreased (P<0.05) in feed supplements under cooling groups. All groups of under cooling system showed shorter days open compared with those under non-cooling system, being the highest with Zn and Niacin supplementats. Zn and Niacin supplementation increased (P<0.05) conception rate under cooling system than those in the under non-cooling system.

A total number of 18 growing males of New Zealand White rabbits aged 5 weeks were randomly divided into 3 experimental groups to study the effects of using different forms of Nigella sativa as a replacement of soybean meal protein on growth performance, and economical efficiency of NZM rabbits. The rabbits of the control group was fed diet free from NS, replacement soybean meal protein by NSM protein was used at levels of 25% in the group (2) and Nigella sativa seed (4kg/tn) used in group (3). The experiment lasted for 60-70 day. The growth performance of the experimental rabbits was studied in terms of average weight gain through out the experimental period, also economical efficiency was calculated for all the rabbits groups studied. The obtained results indicated that the highest values of body weight, body weight gain, and economical efficiency were observed for groups fed Nigella sativa meal and seed at the end of the experiment, followed by control group. The results showed that NSM protein can be used in rabbits diets up to 25 % of soybean meal protein during growing period without any adverse effect on performance.

The present study was carried out to investigate the effect of using graded levels of Bio-Nutra 200 and Natuzyme with plant protein diets on the performance of broiler chicks. three dietary levels (0.25, 0.50 and 0.75g/kg) of either Bio-Nutra 200 (probiotic) or Natuzyme (enzyme preparation) in addition to the control without supplementation were used. Therefore, seven experimental diets were formulated to have similar crude protein and metabolizable energy contents during both starter and grower periods. Three hundred thirty six one-day-old unsexed Hubbard broilers were randomly distributed to seven equal experimental groups. The chicks were fed the experimental starter diets from one day to 21 days of age and switched to feeding the experimental grower diets from 22 to 42 days of age. All chicks were managed similarly and had free access to feed and water during both the starter and grower periods. The criteria of response were live body weight, weight gain, feed intake, feed conversion, economical efficiency of growth, carcass traits, nutrient digestibility [dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), crude fiber (CF) and nitrogen-free extract (NFE), and ash retention], some blood plasma parameters [total protein, albumin and cholesterol , and activity of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in blood plasma].
The obtained results for the whole experimental period could be summarized as follows: Birds fed either the probiotics- or enzymes-supplemented diets had significantly higher means of final live body weight, weight gain, feed conversion, economic efficiency of growth, nutrient digestibility (i.e. DM, OM and CF), with insignificant differences among them, compared with their control counterparts.
In general, birds fed either probiotics- or enzymes supplemented diets achieved significantly higher means of most carcass traits and some blood parameters compared with birds fed control diets; however, AST and ALT were negatively affected. The other criteria were not affected by level of both feed additives. In conclusion, the current study may indicate beneficial effects of adding probiotics and exogenous enzymes (particularly with the level of 0.075 g/ kg) to broiler diets.

A total number of 45 of Bovans laying hens at 42 weeks of age were randomly distributed into five experimental groups and treated with different levels of vitamins A; E and selenium to investigate their effects on some important tissues (ovary and spleen) of laying hens under heat stress conditions.
Histopathological examination revealed that ovaries of birds received diet containing 500 mg/kg diet of vit. E with 0.25 mg/kg diet of selenium were moderately activated with an increase of primary oocytes. However, the spleen showed moderate hyperplasia of the white pulp and focal thickening of the splenic capsule. Birds fed on diet containing 8000 IU/kg diet of vit. A and 500 mg/kg diet of vit. E showed moderate activity of ovarian follicles with hypercellular stroma. The spleen showed hyperplasia in the lymphoid cells of white pulp and an increase in the reticuloendothelial cells (REC). Birds that received diet containing 16000 IU/kg diet of vit. A showed slight increase in the primary and growing ova as compared to control. The spleen revealed moderate hyperplasia in the white pulp area. Moreover, birds received diet containing 16000 IU/kg diet of vit. A, 500 mg/kg diet of vit. E and 0.50 mg/kg diet of selenium showed active ovaries containing variable sized ova and numerous blood capillaries. The spleen showed hyperplasia of the white pulp area.
It is concluded that the addition of vitamins A; E and Se to layer diets activated the ovarian function and enhanced the immune response of laying hens under heat stress conditions.
