The possibility of using lysolecithin from rice bran oil (LL) in the diet of broiler chickens was explored. Lysolecithin was included in diet at graded levels (0, 0.05, 0.1, 0.2, 0.4, 0.8, 1.6 and 3.2 % in diet) and fed to a total of 640 broiler chickens from 0 to 35 d of age. The diets were isonitrogenous and isocaloric. Body weight was higher in the group fed the highest level (3.2 %) of LL. Feed intake was significantly (p less than 0.01) lower in the groups fed 1.6 and 3.2 % LL in comparison to control, whereas feed conversion efficiency was significantly (p less than 0.01) improved at the highest level of LL (3.2 %). Serum concentration of protein, total cholesterol and triglycerides as well as slaughter parameters, organ weights, fat deposition in liver and muscle, and SRBC response were not affected. The fat digestibility was significantly (p less than 0.05) improved at the higher levels (1.6 and 3.2 %) of LL in diet. It is concluded that rice bran oil LL could be safely used in broiler chicken diet and at dietary levels of > 1.6 % the LL improved the body weight, feed conversion efficiency and fat digestibility in broiler chickens.

Green Seaweed

Using seaweeds as sources of nutrients and beneficial bioactive compounds can promote sustainable production of functional poultry products. This study investigated the physiological and meat quality responses of Cobb 500 broiler chickens to graded levels of green seaweed (Ulva sp.) meal (SWM). Three hundred, two-week-old male chicks (159.3 ± 11.76 g live-weight) were randomly assigned to five diets formulated by diluting a standard broiler diet with SWM at 0 (SW0), 20 (SW20), 25 (SW25), 30 (SW30) and 35 g/kg (SW35). There were neither linear nor quadratic trends (p > 0.05) for overall feed intake, overall growth performance and carcass and meat quality traits. Overall feed conversion efficiency (R2 = 0.192, p = 0.018) and spleen weights (R2 = 0.182; p = 0.020) linearly declined as SWM levels increased. Linear and quadratic responses (p > 0.05) were observed for lymphocytes. There were linear effects for meat pH except on day 7 of storage. Meat lightness (L*) linearly increased whereas meat redness (a*) quadratically responded to SWM levels (day 3 of storage). While an optimum inclusion level could not be established for seaweed based on growth performance, improvements in some meat shelf life indicators were observed in the broilers reared on seaweed-containing diets.

The Mean

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 > 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 < 0.05). Interestingly, no significant difference in body weight gain was observed between the probiotic and the control groups by day 42 (P > 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.

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.

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
