An attempt was made to investigate the responses of broiler to feed the compound feeds of different feed mills located in Bangladesh. Keeping this view in mind, a total of 260 of star-bro broiler chicks were fed on compound diets in the age duration of day old to 38 days to compare the performance of broilers of different dietary groups. All the forms of feed were of identical (pellet feed) as well as same management and environment were provided for all the treatments. The body weight gain was highest in T2 dietary group (P < 0.01) which was statistically similar with T1 group. Feed intake of the 5 treatments differed significantly (P < 0.01). T1 dietary group showed high trend of feed consumption. Higher FCR value (P < 0.01) was observed for T5 dietary group which indicated low feed conversion efficiency. On the other hand, T2 and T1 dietary groups showed better feed conversion efficiency. Survivability percent of all treatments was not differed significantly (P>0.05). Significant differences were obtained for meat yield parameters such as body weight, blood loss, shank weight, liver weight, abdominal fat, dressed carcass and edible carcass weight. On the other hand, non significant differences were obtained for feather loss, gizzard weight, spleen weight, heart weight, head weight. Except the body weight (P < 0.01) no significant results were observed for sex(s) as well as interaction between treatment and sex effect for all other meat yield parameters. The results of this experiment from biological responses of birds gave an impression that compound feeds of the feed mills T1, T2 and T3 were found to be better than those feeds of T4 and T5 feed mills for the production of commercial broiler for the age duration of day old to 38 days of age.

It is related leg problems to the realization of the necessity of doing a detailed analysis of the phenotype correlations between body weight and exterior measurements. As a result of the study, lower coefficients have been obtained of the correlation between the girth of the tarso metatarsus on one hand, and the body weight and the girth behind the wings, on the other hand (respectively 0.563 and 0.608), compared with the one between the body weight and the girth behind the wings (0.898). It is advisable in the selection of ostriches to take into consideration the necessity of a higher phenotypic correlation between the girth of the tarso metatarsus on the one hand, and the body weight and the girth behind the wings on the other hand, with a view to preventing leg problems.

The study aimed to investigate the impact of supplementary feeding on the young camels calve growth rate and daily gain. A total of 16 heads of young male camel calves from the Arabic camel breeds were selected and div ided into four equal groups (1, 2,3,4). Four heads of camel calves in each group, their body weight ranged from 176 - 220 kg. Experimental animal in group one was control supplemented nothings jus t depend on the natural range land, group two was feed on watermelon seeds, group three was allowanced concentrated diet composed of ground nut cake and the animals in group four intake mixture diet consist of watermelon seeds and ground nut cake 50% for e ach. The body weight of the experimental animal was determined biweekly using table balance. The random complete experimental design was used and the Analysis of variance and Tukey test were applied for data analysis and means separation. The results indic ated that the average Body weights of the camel calves were 174.75±3.3, 275.93± 9.0, 241.50± 8.5 and 236.50±8.2 Kg, in group one, two, three and four respectively. The higher body weight was recorded in group two (275.93±9 Kg) in which the animals feed on watermelon seeds and followed by group three and four (241.50± 8.5 and 236.50±8.2) respectively. On the other hand the less camel calves body weight was obtained in group one (control) that experimental animals not intake supplementary feeding. Highly diff erences (P ≤ 0.01) were obtained in the body weight between the groups. The daily gain of the first group, second, third and fourth were 214±12g, 624±28g, 542±19g and 528±12g, respectively, while no significant differences (P ≥ 0.01) between diets groundnut cake 242 kg and mixture diet 237 kg. The protein content was higher in ground nut cake 41% when compared to the protein content in watermelon seeds 36%, on the other hand the percentage of fat was highest in watermelon seeds 27.8% compared to ground nut ca ke 13.4%.

1. Four treatments were employed in the rearing of colostrum-deprived piglets from birth to 14 days of age. The performance of the artificially reared piglets was compared with that of conventionally raised sow-suckled piglets.2. Statistically significant differences in growth rate were found in favour of piglets receiving 22% cows' milk solids from birth when compared with the sow-suckled group and the other artificial treatments.3. Small non-significant differences in feed conversion efficiency were found between the artificial treatments with one exception. Pigs receiving 22% cows' milk solids from birth possessed superior conversion figures when compared with pigs receiving 6% cows' milk solids after birth.4. Each of the artificial treatments led to fewer deaths than the sow-suckled group.5. Pigs on the artificial treatments did not undergo such rapid changes of serum protein profile as did the sow-suckled piglets. Serum protein values for the pigs on the artificial treatments rose from approximately 33% of the levels in the sow-suckled group at two days of age to approximately 60% at 14 days of age.

The production of biomass and antibacterial extracellular products by Lactobacillus casei subsp. casei CECT 4043 was followed in both batch and in realkalized fed-batch cultures. Enhanced concentrations of biomass and antibacterial extracellular products were obtained with the use of the latter fermentation technique in comparison with the batch mode. The culture obtained by fed-batch fermentation was mixed with skim milk and used to prepare a probiotic feed for weaned piglets. To test the effect of the potentially probiotic culture of L. casei on body weight gain, feed intake, feed conversion efficiency, and on fecal coliform counts of piglets, two groups of animals received either feed supplemented with the probiotic preparation or avilamycin for 28 days. The control group was fed nonsupplemented feed. At the end of the administration period (day 28), the groups receiving probiotic and avilamycin exhibited the highest average body weight gain values, although the mean feed intake and feed conversion efficiency values were not different among the groups (P &gt; 0.05). For the entire experimental period (42 days), the control group exhibited the lowest feed intake value, the probiotic group exhibited the highest feed conversion efficiency value, and the antibiotic group exhibited the highest body weight gain (P &lt; 0.05). Interestingly, no significant difference in body weight gain was observed between the probiotic and the control groups by day 42 (P &gt; 0.05). Fecal coliform values decreased (although not significantly) by day 28 in the three groups. However, the mean counts returned to pretreatment levels by day 42 in all groups.

This experiment was conducted in animal felid/ University of Baghdad/ College of Agriculture/ Animal production from 9/11/2016 until 9/1/2017. Twelve growing Awassi ewes lambs weighted 29.13 ±1.50 kg and 8-10 month old were used in this study, the lambs were divided into three individual groups (4 animals/ group) receive the dietary treatments contain 0.2 and 4% tallow, animals were fed concentrate at 2.5% of body weight, Alfalfa hay was given ad libitum basis as the roughage, The results found that: No significant difference between groups in total and daily concentrate, roughage and total feed intake, However, final body weight not affected by the experimental diets, total and daily weight gain had higher values (p<0.05) in diets containing 2 and 4% tallow, feed conversion efficiency improved significantly (P<0.05) in 4% tallow diet compared to other groups. It can be concluded that added tallow to sheep diets improved some productive performance such as total and daily weight gain, feed conversion efficiency. Excess animal fats from human consumption can be used as an energy source in ruminants feeds. Thus benefiting from excess animal fats from human consumption as a source of energy in ruminants' rations.

The effects of partial replacement maize with the graded levels of sundried cassava peels in the finisher ration of cockerels on the yields of various cut-up pieces of eviscerated carcass were determined  in a 7-week study using 2,835 13-week old cockerels of Isa White breed. Seven finisher rations containing 0, 5, 10, 20, 25 and 30% sundried peels were respectively given to a group of 405 cockerels. The results showed that the birds fed 25% and 30% cassava peel rations had the least response in terms of body weight and eviscerated weight. The proportions of head, shank and viscera were significantly higher in the cockerels fed those rations than those fed with lower grades. This indicates that 25  and 30%  cassava peel rations induced the development of inedible offals at the expense of edible meat. Finisher ration containing 20% cassava peels supplied the optimum nutrients for optimum optimum performance in terms of eviscerated yield, growth, body weight and feed conversion efficiency beyond which these parameters started to decline. The results also showed that the low cost of production of cockerels fed rations of cassava peels (30%) overcompensated for the drop in performance, Including 20% cassava peels in the cockerel finisher ration for optimum edible meat yield and 30% cassava peels for the potential economic gain is therefore recommended.

Weight gain, shoulder height and feed intake responses to immunization against somatostatin (SRIF) were examined in three experiments with a total of 78 lambs. Initial immunizations against SRIF occurred when lambs were 4, 8 and 3 wk old for exps. 1, 2 and 3, respectively, with booster immunizations 2, 4, 6, 8 and 10 wk later. Control lambs were left untreated except in exp. 3 where one group of control lambs was immunized with human serum alpha globulin. Treated lambs were immunized with SRIF conjugated to human serum alpha globulin. Experiments were terminated when lambs reached 45 kg body weight. SRIF immunization did not alter lamb shoulder height or feed conversion efficiency. Rate of gain of ram and wether lambs, but not ewe lambs, was improved by SRIF immunization. Wether lambs in exp. 1 and ram lambs in exp. 2 gained 21 and 15% more, respectively, than their controls by 20 wk of age. In exp. 3, SRIF-treated 3/4 Romanov ram lambs gained 13% more than their controls by 19 wk of age. However, SRIF-treated 7/8 Romanov lambs gained only 3% more than controls during this time. In conclusion, immunizing wether and ram crossbred lambs against somatostatin increased their growth rates sufficiently to reduce the time needed to reach market weight by 2–3 wk. However, feed conversion efficiency was not improved by somatostatin immunization. Key words: Somatostatin, SRIF, immunization, growth rate, lambs
