In trial 1, caged broiler chicks were reared to 28 days on corn-soybean meal diets containing 60 ppm salinomycin or 99 ppm monensin with either 0, 0.05, 0.1 or 0.15% supplemental DL-methionine at metabolizable energy levels of 13.14 or 12.13 MJ/Kg. Monensin, but not salinomycin, depressed (P < 0.01) female body weight. Male birds were influenced by the salinomycin treatment resulting in increased feed efficiency. There were no significant interactions between treatments. Two subsequent trials involved floor-reared male and female birds to 49 days. Diets contained 0 or 60 ppm salinomycin in low (12.01 MJ ME/kg starter, 12.38 MJ ME/kg finisher) or high (13.33 MJ ME/kg starter, 13.63 MJ ME/kg finisher) energy regimens. Methionine levels were adjusted to the National Academy of Sciences-National Research Council (NAS-NRC) (1977) level of 1.56 g/4.184 MJ ME as a control treatment. Methionine treatments were obtained by supplementation or not of a corn-soybean meal basal. Salinomycin reduced feed intake (P < 0.01) of both male and female birds, and reduced body weight (P < 0.01) in males. Salinomycin improved (P < 0.05) feed efficiency in female birds. High levels of methionine supplementation reduced (P < 0.05) feed intake when the diet contained salinomycin, but not without the medication. There was a salinomycin × methionine interaction (P < 0.01) for feed efficiency. Salinomycin resulted in improved (P < 0.01) carcass fleshing grade at the low and standard levels of methionine.

Feed Supplementation

The experiment was conducted at the livestock production and management unit, faculty of agriculture. MGCGV Chitrakoot – Satna ( M.P.). To complete the research work following steps were followed. Day old 75 broiler chicks (DOC) of same hatch were produced and reared in of Deep litter system. The chicks were weighed, leg banded and distributed randomly into five groups of 15 chicks each as treatment. Chicks of each treatment were further divided into three sub groups of five chicks in each in Randomized Block Design (RBD). Chicks of each sub group were accommodated comfortably in deep letter system providing 1 sq. ft./ chick. Chicks were fed standard starter ration upto 3 weeks age (1 to 21 days) and then broiler finisher ration upto 3-4 weeks (22-28 days). An experiment was conducted with DOC to 75 broilers chicks divided into five groups T0, T1,T2 and T4 which were supplemented with turmeric and Tulsi leaves powder @ 1.0g, 2.0g, 3.0g and 4.0g/kg of broiler ration, respectively. Weekly observations were recorded for live body weight, weekly gain in weight, weekly feed consumption and feed conversion of broiler for four weeks. Based on the results of the experiment, it may be concluded that feed supplementation with turmeric (Curcuma longa) powder influenced the body weight, gain in body weight, feed intake and feed efficiency of broiler chicks. Based on the result of the experiment, it may be concluded that feed supplementation with turmeric + Tulsi leaves powder influenced body weight, gain in body weight, feed intake and feed efficiency of broiler chicks. Based on feed intake and feed efficiency, the best performance of broilers was obtained with feed supplementation of 3g turmeric + 3g Tulsi powder per kg of standard ration (T3), followed by 4g turmeric + 4g Tulsi leaf powder (T4). Treatment T3 was economically superior over all other treatments and control.

Five corn-soybean-based diets were formulated to contain 0, 15, 20, 25, or 30% raw peas and fed for 35 d to ninety-six 21-d-old pigs. Raw peas were included at the expense of corn and soybean meal. Increasing levels of raw peas depressed daily gain (P = 0.07), feed intake (P = 0.04) from days 21 to 56. Specifically, pigs fed diet with 25% peas had 19 and 25% lower average daily gain (ADG) and average daily feed intake (ADFI), respectively, than pigs fed the diet with 0% peas. The body weight (BW) was also linearly reduced (P = 0.10) on day 56. However, diets did not affect feed efficiency. Key words: Growth performance, peas, pig

One hundred and twenty Anak broiler chicks of both sexes were fed furazolidone (additive) in feed to study their growth/weight gain response. The birds were grouped into four, A, B, C, and D of 30 chicks each Treatments B, C and D were administered with furazolidone in feed at the following dosage rates: 0.008%, 0.004% 0.002% respectively. Group A served as control in which furazolidone was not added in the feed. All the groups, (except in feed intake where the control differed significantly) had no significant differences in body weight gain, feed efficiency, and feed intake. It was concluded that it is not necessary to use furazolidone as a growth promoter in broiler feeds.

Maintenance Requirements

Abstract This study determined feed intake behavior, performance, feed efficiency, and maintenance requirements of bulls with high and low residual feed intake and body weight gain. Data were collected from 42 weaned Nellore bulls (initial BW 260 ± 8.1 kg; age 7 ± 1.0 mo) housed in a feedlot in a group pen that contained electronic feeders. Individual dry matter intake (DMI) was recorded daily and body weight (BW) was measured every 28 d over a 140-day period. Indexes of average daily gain (ADG), feed efficiency, and residual feed intake (RFI) were calculated. Residual feed intake and gain (RFIG) was calculated according to previously published equations. Frequency of meals, duration per visit, and time spent feeding per day were recorded as feeding behavior measures. Maintenance requirements were calculated according to the BR-CORTE system. High RFIG bulls had lower DMI (P &lt; 0.01), lower final BW (P &lt; 0.01), and were more feed efficient (P &lt; 0.01) than low RFIG bulls, but both groups had similar ADG (P = 0.55). No differences in feeding behavior were observed between the two groups (P &gt; 0.05). The net energy requirements for maintenance, metabolizable energy for maintenance, and efficiency of metabolizable energy utilization were 76.5, 122.68 kcal/EBW0.75 daily, and 62.4%, respectively for high RFIG bulls, and 89.2, 143.76 kcal/EBW0.75 daily, and 62.0% for low RFIG bulls. This study reveals that low RFIG bulls are less feed efficient and have greater maintenance requirements than high RFIG bulls (0.16 ± 0.006 and 0.18 ± 0.006, respectively). As low RFIG eat more, and in beef cattle, feeding behavior is associated with methane emissions, we suggest further research evaluating this relationship be conducted. In addition, selection for high RFIG cattle would improve feed efficiency, reduce production costs, and could potentially reduce methane emissions.

Two Hundred and six day old Fulani Ecotype chicks (FEC)were used to investigate the effect of feeding two types of diet (Chick starter diet and Broiler starter diet formulated to meet standard nutritional requirement of pullets and broiler chicks) on growth traits and performance from O to 8 weeks. The broiler starter diet contained 23% Crude Protein (CP) and 3000Kcal/kg Metabolizable Energy (ME), and the Chick starter diet contained 21% CP and 2800Kcal/Kg ME. The growth traits measured were body weight (BW), body length (BL), body girth (BG), wing length (WL), thigh length (TL), drumstick length (DL), keel length (KL), and shank length (SL), while chicks performance were estimated from feed intake. feed efficiency, growth rate and weight gain. Average body weight of chicks fed broiler starter diet were significantly (P<0.05) higher from week 1 to 8. Chicks fed broiler starter diet exhibited numerically higher BL, BG, WL, TL, DL and KL than those fed chick starter diet at all ages and differences were significant (P<0.05) at some ages. Chicks fed broiler starter diet significantly (P<0.05) consumed more feed at week 1 and 2, and they gained more weight than those fed chick starter diet from 0 to 4 weeks (120.51 vs. 97.89g), and 5-8 weeks (255.11 vs. 239.13g). Feed efficiency in chicks fed broiler starter diet was relatively higher by 13.21% than observed in those fed chick starter diet from day old to 4 weeks and this translated to faster growth rate during the period in the former group (34.30% Vs.32.67%). This Study shows that the broiler starter diet produced superior growth traits and better feed efficiency in Fulani Ecotype chicks.

Substitution Level

The objective of the present study was to evaluate the effect of substitution level of soybean meal by babassu pie on the performance and cost feed rations to broilers of one to 21 days of age. Two hundred male broiler chicks at one day of age were used, distributed in a completely randomized design with four treatments (0, 10, 20 and 30 % substitution of soybean meal by babassu pie) with five repetitions of 10 broilers each. The performance (weight gain, feed intake, feed conversion and water intake), organ biometrics, feed cost per kg and per kilogram body weight were evaluated. The substitution of soybean meal by babassu pie was significantly in (P<0.05) negatively weight gain, feed conversion, water intake and body weight at 21 days of age, with no effect (P>0.05) on feed intake. The levels of substitution of soybean meal by babassu pie did not affect (P>0.05) the relative weights of the heart or liver, or the relative weight or length of the small intestine; however, it did affect (P<0.05) the relative weight of the gizzard. The lowest cost per kg was obtained from weight gain satisfaction with the diet of 0% babassu pie, which resulted in a higher gross margin for food. The replacement of soybean meal by babassu pie impaired the performance of broilers from one to 21 days of age, being technically and economically unfeasible.

Recycled paper products were evaluated as litter material for broilers; parameters were growth performance, carcass quality, and footpad problems. One hundred sixty-eight broiler chicks were raised to market age (42 d) in an open-sided poultry house located at the Lajas Agricultural Experiment Station Small Animal Research Farm. Birds were assigned to 12 floor pens bedded with either rice hulls (RH) as control; a 50:50 mix of RH and shredded white paper (SWP); or a 50:50 mix of RH and shredded newspaper (SNP) according to a completely randomized design replicated four times. Traits measured were body weight, feed intake, feed conversion, carcass yield, breast blister score, footpad burn score, and mortality. Litter moisture percentage was assessed at 14, 28, and 42 d of age. Litter material had no influence on body weight, breast blister score, or bird mortality. However, birds raised on SWP had lower feed intake and higher body weight than those raised on RH and SNP. No significant differences in feed conversion were observed among treatments from 7 to 28 d of age. At 35 and 42 d, birds raised in SWP had significantly lower feed conversion than controls, whereas feed conversion of birds raised in SNP did not differ from that of the other treatments. No differences were found for carcass yield among treatments. At all sampling times, litter moisture percentage was significantly higher in SNP than in the control. No litter caking problems were observed in any of the treatments. Significant differences in footpad burn scores were observed among all treatments, with birds raised on SNP having higher scores (severer lesions), than those on SWP and RH.The results suggest that recycled paper products could be an excellent alternative bedding material for broilers. The use of SWP as litter appears to improve broiler performance and reduce the incidence of footpad problems.

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.

A completely randomized design (CRD) was used with a total of 160 day-old commercial broiler chicks which were randomly assigned to four treatment groups with five replicates into 20 pens and brooded. Feed and water were provided ad libitum. From day old chick to 21 day, the broiler chicks were fed Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (3% fish meal and 30% soybean meal, 1: 10) was served as control diet, Diet 3 (2% fish meal and 30% soybean meal, 1: 15) and Diet 4 (1.5% fish meal and 30% soybean meal, 1: 20). From day 22 onwards, the broiler chicks were fed finisher diet, Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (2.6% fish meal and 26% soybean meal, 1: 10, serve as control diet, Diet 3 (1.8% fish meal and 27% soybean meal, 1: 15) and Diet 4 (1.3% fish meal and 26% soybean meal, 1: 20). Weekly performances and mortality are measured. By feeding FS5 diet (5% fish meal and 25% soybean meal), the heavier body weight, increased feed consumption and feed conversion ratio of broiler chicks was observed when compared to that of other treatment groups. Conclusively, it is obvious that the ratio of dietary fish meal to soybean meal 1: 5 (FS5) improved body weight but the lower feed efficiency of this diet should be considered in economical point of view.
