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 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.

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

Abstract This study aims to improve the production performance of Murrah buffalo which covers average weight gain, feed consumption, and feed conversion by increasing probiotic feed. The research was conducted on the herd of Murrah buffalo at Kelok Rambai, Kapau Village, West Sumatera, Indonesia. Fifteen Murrah buffaloes with three to five years of age were used in the research. There were three treatments conducted including P1 = basal feed + probiotics; P2 = P1 + concentrate (cassava leaf pellet); and P3 = P1 + commercial concentrate (pellet). All three treatments were also given 7 cc/head/month of probiotics. The results of the study with probiotic feeding on Murrah buffalo showed the average feed consumption of P2 (36.55), P3 (35.99), P1 (35.74) and daily weight gain (DWG) P2 (1.09 kg/head/day), P3 (0.91 kg/head/day), P1 (0.55 kg/head/day) did not show a significant difference, while in feed conversion, P2 (0.68 ), P1 (0.46), P3 (0. 31) it showed a significant difference (p>0.05). This study concludes that the provision of basal ration plus cassava leaf pellets showed significant results on feed conversion in Murrah buffalo but did not show significant differences in feed consumption and DWG. However, it showed a substantial enough average of P2 that could be used as a feed supplement in Murrah buffalo.

Feed Utilisation

From the published data summarised in Table 1, it was calculated that, at an average degree of feed restriction of 15·8 %, daily weight gain decreased by 12·50% (or 0·78% for each 1% restriction), feed conversion efficiency improved by 3·96% (or 0·31% for each 1% restriction) and backfat thickness diminished by 7·63% (or 0·53% for each 1% restriction).Equations were calculated to show the degree to which daily weight gain, feed conversion efficiency and backfat thickness change with increasing feed restriction (Figures 1, 2 and 3).As the degree of feed restriction increases, the decrease in daily weight gain becomes relatively greater and the decrease in backfat thickness relatively smaller. Efficiency of feed utilisation, however, improves at first, but eventually decreases as restriction becomes more severe.It is thought that the equations found can be used, within certain limits, to calculate the average effects of feed restriction for different breeds of pigs, which when fed ad libitum consume 2·7 kg. meal ration (of normal composition) per day and have a growth rate of about 750 g. daily from 30 to 90 kg., and backfat thickness of about 37 mm. when kept under average environmental conditions.

Sixty 7-week-old New Zealand White rabbits were randomly distributed into 5 equal experimental groups. The experimental rabbits were fed the tested diets till 14 weeks of age during summer season. The basal diet without feed additives (control; T1) and the other experimental diets were supplemented with enzymes at 0.5 g/kg (T2), organic acids at 1.0 g/kg (T3), Beta-pro at 0.2 g/kg (T4) or their combination (T5). The criteria of response were body weight, weight gain, feed consumption, feed conversion ratio, some blood constituents, carcass traits and economic efficiency. The obtained results can be summarized as follows: Positive effects of feed additives were observed on live body weight, daily weight gain and feed conversion of growing rabbits. There were no significant effects on blood parameters or carcass traits due to feed additives. It can be concluded that dietary Beta-pro (enzymes+probiotics) or a combination of enzymes, organic acids and Beta-pro at the tested levels can be used to improve the rabbit performance, with no adverse effects on carcass characteristics or blood parameters.

The present study proposes to examine the effect of dietary levels of metabolizable energy, under a fixed nutrient:calorie ratio, on the production performance; body fat and protein deposition; and carcass characteristics of free-range broilers from 1 to 84 days of age. Nine hundred unsexed chicks were allocated to six treatments in a completely randomized design with six replicates of 25 birds each. Treatments consisted of diets with varying levels of metabolizable energy (2700, 2800, 2900, 3000, 3100 and 3200 Kcal ME/kg of diet) and a fixed proportion of nutrients relative to the energy level according to the nutritional requirements for each rearing phase. Body weight, weight gain, feed intake, feed conversion, production viability, metabolizable energy intake, protein intake, lysine intake, body fat deposition, body protein deposition and carcass characteristics were evaluated. Data were subjected to analysis of variance and, later, to regression analysis. Increasing levels of metabolizable energy, coupled with a fixed nutrient:calorie ratio, reduced feed intake, increased body weight and weight gain, improved feed conversion and did not affect carcass characteristics. In conclusion, adjusting the nutrient supply according to the dietary energy level improves production performance by improving feed conversion, ensuring adequate nutrient intake and preserving fat and protein deposition in the carcass when the metabolizable energy level is raised up to 3200 Kcal/kg in all rearing stages.

ABSTRACT. Tempe of soybean is fermented soybean with Rhizopus ologosporus fungus. From a result of researchers, it is the fact that tempe can increase valuable of nutrion and digest capacity and also produce antibiotic . Utilization of abtibiotic in chiken food as stimulus growth in not recommended because it can cause resistance a certain germ and it is presume there are antibiotic residu in egg and chiken meat. It is hope that the use of fermented soybean oil meal can increase nutrient value and digest capacity as well as produce antibiotic, so that it can get a better growth and over come a problem of using antibiotic in chiken food. The study was conducted to evaluate the effect of fermented soybean oil meal utilization in the ration on body weight gain, feed consumption, feed conversion and mortality. The study use 80 unsex day old chick broiler CP-707 and conducted at Poulty Laboratory Product Agriculture Faculty, Syiah Kuala University. Chiken were putting in 27 houses unit, each unit contain of four chiken. The design of experiment was Completely Randomized Design, four treatments and five replication. The treatments were ration contained 0%, 5%, 10% and 15% fermented soybean oil meal as replace the use of soybean oil meal. The protein and energy content of all dietary treatments were equally composed from six weeks investigation, were body weight gain, feed consumption, feed conversion and mortality. The result of the study indicated that up to 10% graded of fermented soybean oil meal in ration were significant difference influenced increase the body weight gain and decrease the feed conversion. The fermented soybeanoil meal) utilization more than 10% were significant difference decrease the body weight gain and increase the feed conversion. If the inclusion was increase the feed consumption would tendency decline. In this study there were no mortality in all treatment. In can be advised from this study that fermented soybean oil meal could be used in broiler ration or in all poulty ration.

Selection For

Thirty-five steers and 37 heifers were grown at pasture and finished in a feedlot to meet Australian domestic market specifications, i.e. 160-200 kg carcass weight with 5-9 mm subcutaneous fat at the P8 rump site. The animals were from lines that had been selected for either high growth rate to 600 days (UPWT) or for low rectal temperature under conditions of high ambient temperatures (TEMP) and from a control line (CONT). They were slaughtered in six groups at fortnightly intervals when liveweight of individuals was estimated to satisfy market requirements. Animals from the UPWT line were heavier at all ages than animals from the TEMP and CONT lines (P< 0.05) and had higher liveweight gains at pasture (P < 0.01). There was no difference between the lines in liveweight gains in the feedlot. At the same carcass weight, UPM animals had leaner carcasses (P < 0.01) but similar levels of marbling to CONT line animals. TEMP line animals were also leaner than CONT line animals (P < 0.0l ) , but had more marbling (P<0.01). There was no significant difference between lines in feed conversion efficiency. Steers were heavier (P < 0.001) than heifers at all ages, grew faster (P < 0.001) except during the immediate post-castration period, had higher feed intakes (P < 0.05) but better feed conversion efficiencies (P < 0.05), and at the same carcass weight were leaner (P < 0-01) and had less marbling (P < 0.05). Meat colour, cooking loss, ultimate pH and meat tenderness did not differ significantly between lines or sexes. These results are discussed with reference to the use of selection for growth or heat resistance to improve growth and carcass traits of beef herds in tropical areas.
