A feeding trial to evaluate the per­formance of finishing steers fed main­ly on sugarcane tops with or without cotton­seed and molasses was conducted in Niono, Mali during the dry season. 96 Zebu steers, weighing between 220 and 250kg were randomly alloted to four groups of twenty-four steers each The performance parameters compared were: feed intake, rate of gain, feed conver­sion and carcass characteristics. The diffe­rences observed for feed intake, rate of gain and feed conversion appear to be more related to roughage level rather than source. There were no nutritional disorders. Results from this initial feeding trial indicate that a sugarcane — derived feedstaffs can be used to constitute a major component of finish­ing steer rations particularly in the dry areas of the tropics where sugarcane tops are regarded as wastes.

The effect of replacing an antibiotic growth promoter in the diet with a probiotic on growth performance, carcass characteristics and nutrient retention was studied in broilers (Vencobb 430) fed with and without meat cum bone meal (MBM). This experiment which lasted for 42 days consisted of six dietary treatments viz., basal diet (BD), basal diet with MBM (MBM), basal diet with antibiotic (AB), basal diet with probiotic (PB), basal diet with MBM and antibiotic (MBM+AB) and basal diet with MBM and probiotic (MBM+PB). Three-hundred, day-old chicks were randomly allotted in the beginning to these six groups. Body weight gain, feed intake and feed conversion ratio were significantly (P less than 0.05) affected at 4th week of age. Overall, highest body weight gain was recorded in birds fed with AB and PB. Inclusion of probiotic in MBM also showed improved body weight gain when compared to MBM group. Highest feed intake and feed conversion ratio was recorded with AB and PB groups. Birds supplemented with MBM+PB showed improved feed intake and feed efficiency when compared to MBM+AB and MBM diet supplemented groups. Higher dry matter, crude protein, calcium and phosphorus retention (P less than 0.05) was observed in birds supplemented with PB or AB in diet without MBM when compared to their control. In MBM supplemented groups addition of PB or AB improved crude protein retention. Birds supplemented with PB or AB with or without MBM showed a significant (P less than 0.05) increase in thigh yield and a non significant reduction in fat yield when compared to their control groups.

Investigations into the performance of Peulh and Maure Zebu breeds of cattle to supplementary feeding of cotton seed and rice bran in addition to grazing natural pasture during the rainy and dry seasons were conducted in the Sahe one of Mali Republic. 96 steers made up of Peulh and Maure Zebu breed with age ranging between 30 and 55 months were grouped into five ._-­the control group grazed on natural pasture alone while four test groups were fed supple­mentary diets in addition to free grazing. Parameters based mainly on feed intake, rate of gain, feed conversion and carcass characteristics showed Maure gained weight significantly (P < - 0.05) faster (318.5g/d) than Peulh (2920) when a feeding trial which lasted 56 weeks was conducted. All steers on test diets performed better than the control except during the second rainy season when a 'compensatory growth' was recorded for the steers under the control. treatment. Younger animals (30 months old) gained weight (337.1g/d) significantly faster (P< 0.05) than the older (55 month-old) ones (273.40). While dressing percentage ranged between 48 and 56, test animals had significantly better dressing percentage of 55.4% (P < 0.05) than the control (48.2%). No diffe­rence was-recorded between the breed or age groups. Animals fed on pasture alone had 10.7% capacity of rumen content as perc­centag€ of carcass weight compared with 7.5% fir test diets.

Feeding Trial

This study was carried out to evaluate the growth performance and carcass characteristics of finisher broiler chickens fed diet containing cooked cocoyam tubermeal as energy source in place of maize. The proximate composition of cooked cocoyam tubermeal showed that it contained 13.11% moisture, 2.60% ash, 3.90% crude protein, 9.45% crude fiber, 1.85% ether extract and 70.13% NFE. In the finisher feeding trial, the cooked cocoyam tubermeal was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each finisher diet was fed to a group of 30 finisher broiler chicken for 4 weeks using completely randomized design. Each treatment was divided into 3 replicates of 10 broiler chicks each. The birds were kept on deep litter and were given feed and water ad-libitum. Parameters measured include ifinal body weight, body weight gain feed intake, feed conversion ratio, carcass characteristics and economics of production. In the finisher feeding trial, the feed intake of the finisher broilers on diets 2, 3 and 4 were similar and compared favourably with those on the control diet. The finisher group on 100% CCYM (diet 5) recorded the lowest feed intake possibly because of the dustiness of the feed. The body weight gain of the finisher broilers on diet 2 (25%) cooked cocoyam tubermeal compared favourably with the control group and was significantly (P<0.05) higher than those on other diets. It appeared that the finisher broilers could not tolerate high levels of cooked cocoyam meal due to dustiness of the feed and its anti-nutritional factors. The cost of production per kg finisher broilers was cheapest for diet 5(100% CCYM) (N356.72) and the costliest was for diet 3(50% CCYM) (N588.28). The internal organs expressed as percent of the live weight were not affected by the treatments. In terms of carcass characteristics, the finisher broilers on diet 2(25% CCYM) recorded the highest breast muscle which was significantly different (P<0.05) from other groups. There were no significant different (P>0.05) on percent back cut, drumstick, head, shank, thigh, neck and wings of the finisher broilers on all the treatments. There were no significant differences (P > 0.05) in percent dressed weight of the finisher broilers on cooked cocoyam based diets. The results of the trial have shown that cooking cocoyam corms (Xanthosoma sagittifolium) for 30 minutes was effective for reducing the cyanide oxalate, tannin, phytic acid and saponin content and that cooking did not affect the proximate composition of tannia. Cooked cocoyam tubermeal could be used to replace maize up to 25% in the diet of finisher broiler chicken without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.

To evaluate the effect of organic chromium (Cr) and selenium (Se) supplementation on performance and carcass characteristics of finishing pigs, 300 castrated males were distributed in a randomized block design with three treatments and five replications of 20 pigs each. Treatments consisted of different diets, formulated to reach or exceed Rostagno et al. (2011) nutritional requirements, as follows: 1) control - basal diet without organic Cr and Se supplementation from 70 to 130 kg of body weight; 2) CrSe70 - basal diet supplemented with 0.8 mg kg-1 of Cr- and 0.6 mg kg-1 of Se-enriched yeast from 70 to 130 kg of body weight; 3) CrSe100 - basal diet without organic Cr and Se supplementation from 70 to 100 kg of body weight followed by basal diet supplemented with 0.8 mg kg-1 of Cr- and 0.6 mg kg-1 of Se-enriched yeast from 100 to 130 kg of body weight. Performance was evaluated by measuring body weight, daily weight gain, daily feed intake and feed conversion ratio. At the end of experimental period, pigs were sacrificed and lean meat percentage, longissimus dorsi muscle depth, back fat thickness, and carcass bonus index were determined using prediction equations generated by the software Hennessy System GP4 after carcass scanning with an electronic probe. Data were submitted to one-way ANOVA and in case of significant differences (P ? 0.05), means were compared by SNK multiple-range test. Daily feed intake (P = 0.008) and feed conversion ratio (P = 0.004) decreased for pigs supplemented with Cr- and Se-enriched yeast from 70 to 100 kg of body weight. Otherwise, pigs supplemented between 100 and 130 kg of body weight increased (P = 0.032) daily feed intake in comparison to the control group. Regarding carcass characteristics, Cr- and Se-enriched yeast supplementation increased (P = 0.019) longissimus dorsi muscle depth in both CrSe70 and CrSe100 treatments. In conclusion, dietary supplementation of Cr- and Se-enriched yeast for castrated male pigs between 70 and 130 kg of body weight increases longissimus dorsi muscle depth in carcass without affecting final body weight or daily weight gain of the animals.

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 An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

Forty Holstein steers, initially weighing 385 kg, were individually fed ground ear corn based on rations containing 0, 0.75, 1.50 or 2.25% NaHCO3. Initial intake of rations containing 1.5 and 2.25% NaHCO3 was low. No differences (P > 0.05) were detected over the 84-day trial in ADG, feed intake or feed conversion. Rumen pH was not affected but ruminal fluid from steers receiving 1.5 and 2.25% NaHCO3 had significantly (P < 0.05) higher percent acetic, lower percent propionic and a higher A/P ration. NaHCO3 did not improve feedlot performance when added to ground ear corn diets full-fed to finishing Holstein steers.

SummaryThe influence of different inclusion levels of a biologically active peptide derived from soybeans by enzymatic hydrolysis, on growth performance, foot pad lesions and carcass characteristics in broilers were examined in this study. Starter (1 to 21 d) and finisher (22 to 42 d) diets, based on maize and soybean meal, were subjected to seven inclusion levels of a commercial soybean bioactive peptide (SBP) product (Fortide, Chengdu Mytech Biotech Co. Ltd., Chengdu, Sichuan, China) at 0.0, 1.0, 2.0, 3.0, 4.0, 5.0 and 6.0 g/kg of diet. All diets were equivalent in respect of energy density, digestible amino acids and other nutrients. A total of 840, one-day-old male broilers (Ross 308) were allocated to 42 pens (20 birds/pen), which were randomly assigned to seven dietary treatments. During the starter period, there was no significant effect of SBP on weight gain and feed intake of the birds. However, a significant (P < 0.05) effect of SBP was observed for the feed conversion ratio (FCR), with SBP inclusion at 3.0 g/kg and above showing lower (P < 0.05) FCR values compared to the diet with no SBP. No effect of SBP was observed for weight gain and feed intake over the whole trial period. However, SBP inclusion tended (P = 0.06) to influence the FCR of birds. Increasing SBP inclusion level resulted in gradual decrease in FCR values, with SBP inclusion at 5.0 and 6.0 g/kg showing lower FCR values compared to the diet with no SBP. Overall, the present study suggests that dietary supplementation of SBP in broiler diets has the potential to improve FCR and to be used as a novel functional protein in poultry diets.
