Sorghum, wheat or corn in soybean meal-based diets with four levels of supplemental methionine were compared for broiler chick growth from 0 to 28 days of age. Wheat and corn supported more rapid weight gains and lower feed-to-gain ratios than did sorghum, regardless of added methionine. A response in rate of gain and feed-to-gain ratios was obtained with the added levels of methionine with each of the three grains.

Two experiments were conducted, using the regression method, to determine the true ileal phosphorus (P) digestibility of maize and soybean meal (SBM), and true ileal calcium (Ca) digestibility of SBM for broiler chickens. The aim of Experiment 1 was to determine true ileal P digestibility of maize and SBM. The experimental diets were formulated with four inclusion levels of each test ingredient to achieve graded concentrations of total P (2.5, 3.0, 3.5 and 4.0 g/kg, respectively). The P concentrations in maize-based diets were adjusted by the inclusion of monosodium phosphate. The Ca:total P ratio in all diets was maintained at 1.35 by the addition of limestone. Experiment 2 was conducted to determine true ileal Ca digestibility of SBM. Experimental diets were formulated to contain four levels of SBM to achieve graded concentrations of Ca (2.5, 3.0, 3.5 and 4.0 g/kg, respectively). Because of the low concentration of Ca in SBM, all diets were supplemented with a similar level of limestone to prevent any Ca deficiency. The Ca:total P ratio in all diets was adjusted to be equal by the addition of monosodium phosphate. In both experiments, titanium dioxide (3 g/kg) was used as the indigestible marker. One-day-old male broiler chicks were fed a commercial starter diet from 1 to 21 days of age. On Day 22, a total of 240 and 120 birds were assigned to eight and four dietary treatments in Experiments 1 and 2, respectively, with five replicate cages and six birds per cage. Birds were fed the experimental diets for 7 days. On Day 29, ileal digesta were collected from the posterior half of ileum, and the true P and Ca digestibility of test ingredients were calculated by linear regression analysis. True P digestibility of maize and SBM were determined to be 33.8% and 42.3%, respectively. True Ca digestibility of SBM was determined to be 45.9%.

Oat Bran

An experiment was conducted to estimate the maximum amount of β-glucan that can be included in a broiler chick starter diet without impairing performance. Oat bran and fat were substituted for corn in a corn–soy diet to provide iso-energetic β-glucan levels of 6.3, 9 and 31 g kg−1 diet. Performance criteria were analyzed for regression on β-glucan level. Impairment of performance was greater for weight gain (W, g day−1) than for excreta condition or feed efficiency. An acceptable dietary β-glucan (G) level (g kg−1) was identified with the predicted performance equal to that of the control diet, from the response surface, W = 28.2 + 0.117 G − 0.00951 G2. Growth impairment was predicted to appear in young broiler chicks only as β-glucan level is increased in iso-energetic diets above 12.3 ± 0.46 g kg−1; conversely 1 and 2% growth inhibitions were predicted when dietary β-glucan levels equal 14.4 and 16.0 g kg−1, respectively.

Residual activity of an Escherichia coli-derived phytase and a commercially available Peniophora lycii phytase along the digestive tract of broiler chicks was compared in order to evaluate their relative resistance to hydrolysis in the digestive tract. Seventy-two 7-d-old male broiler chicks were grouped by weight into six blocks of three cages with four birds per cage. Three corn-soybean meal-based diets were randomly assigned to cages within each block. The three diets were a low P diet containing 3.9 g P kg-1 diet; and low P diet plus either E. coli-derived phytase or the P. lycii phytase at 1000 units kg-1 of feed. The chicks were fed experimental diets from 8 to 22 d of age. At the end of the study, chicks were killed and the contents of the crop, proventriculus and gizzard, jejunum and ileum were collected, freeze-dried, ground and analyzed for phytase activity. Escherichia coli-derived phytase had more residual activity at the proventriculus and gizzard, jejunum and ileum when compared with the P. lycii phytase (P < 0.0001). The E. coli-derived phytase may be more resistant to hydrolysis in the digestive tract when compared with the P. lycii phytase.

There are concerns about inclusion of antibiotics in the feed of broiler chickens, because of the development of antibiotic resistance, leading to a search for alternative feed additives. Turnip extract is known to have antibacterial properties but has not been tested in the diet of broiler chickens. We allocated 200 broiler chicks to receive one of four levels of turnip extract in their water, 0, 150, 300 or 450 ppm, or a standard antibiotic, Virginiamycin, over a 42-day growing period. Although initially there were detrimental effects of providing 450 ppm, overall the 150 ppm level of supplementation increased weight gain, compared with birds given Virginiamycin, and decreased gizzard weight. Birds given 150 ppm or Virginiamycin had increased low-density lipoproteins (LDLs) and reduced very low-density lipoproteins (VLDLs) in their blood serum and reduced antibody responses to sheep red blood cells, compared to birds in the 450 ppm treatment. Birds given turnip extract at 450 ppm had fewer Gram-negative lactose and coliform bacteria than those provided with no turnip extract, and those provided with 150–300 ppm had the same as those provided with Virginiamycin. Turnip extract could potentially replace antibiotics included in the feed of broiler chickens for growth promotion and the control of bacterial infection of the gastrointestinal tract.

Castor Meal

The experiment aimed to evaluate the feeding behavior of Santa Inês lambs fed diets containing different levels of detoxified castor meal in the concentrate. Twenty-four sheep with an average body weight of 18.5± 2.26 kg, at four months of age, were distributed in a randomized complete design with four treatment and six replications. Treatments consisted of four levels of castor meal (0, 33, 67, and 100%) replacing soybean meal. Animals underwent a 15-day adaptation period and an experimental period of 84 days. The diet was composed of 60% sugarcane silage and 40% concentrate, on a dry matter basis. Animal behavior (idle, rumination, and feeding activities) were observed visually for two 24-h periods with 5-min intervals, and recorded. The number of rumination chews and the time taken to ruminate each cud per day were counted using a digital stopwatch. Dry matter (DM) intake was not affected by inclusion of castor meal in the concentrate, averaging 884.02 g day?1. The feeding activity was not affected by addition of castor meal. Rumination time increased linearly, whereas the idle and rumination times decreased linearly with addition of castor meal. Feeding time, expressed in min per kg of DM and NDF, was not influenced by the inclusion of the meal in the diet, averaging 373.3 and 880.0 min, respectively. The number of chews and the time taken to ruminate each cud were not changed by inclusion of castor meal in the diet. Feed efficiency, expressed in grams DM and NDF per hour, was not influenced by castor meal inclusion in the diet. Rumination efficiency expressed in g DM h?1 decreased, but was not affected when expressed in g NDF h?1. Total replacement of soybean meal by castor meal in the concentrate does not affect the feeding time or feed efficiency of feedlot sheep, but leads to a small reduction of their rumination efficiency. Thus, we recommend the inclusion of castor meal in sheep diets at the levels tested in this study.

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.

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.

Enzyme supplementation in diets based on corn and soybean meal can improve the productive performance of broilers. Thus, we aimed to evaluate the effect of the inclusion of different levels of an enzyme complex consisting of phytase, protease, xylanase, ?-glucanase, cellulase, amylase, and pectinase, for diets based on corn and soybean meal, on the parameters of carcass yield and meat quality of broilers. Six hundred broiler chicks were used, and the animals were females with one day of age, from the Cobb 500 strain, and distributed in a completely randomized design, with five levels of inclusion of the enzyme complex (0, 100, 200, 300 and 400), and six repetitions, with twenty animals each. The carcass yield and meat quality were evaluated at 35 and 42 days of age. We evaluated the characteristics of weight loss by cooking (WLC), shear force (SF), water holding capacity (WHC), pH, lightness (L*) and color (a* and b*). The parameters of performance, carcass yield and carcass parts, and meat quality were not affected by the enzyme supplementation of diets fed to broiler chickens (P >0.05), except for the performance characteristics of the breast and the wings at 42 days of age (P < 0.05).

Grasscutter serves as a major tool for improved household income generation, nutrition and bio-diversity in Nigeria. It provides a quick turnover, foreign exchange earner and reduce unemployment rate of the country.In order to assess the feeding values of concentrates used as supplement, studies were conducted in captivity to evaluate the performance of Grasscutter (Thryonomys swinderianus) using 20 growing Grasscutters comprising 16 females and 4 males who were balanced for weight and grouped into four treatments. Inclusion of whole cassava meal that was incorporated at 80% of the total bulk acted as the control(T0) while 10% of whole cassava root meal was replaced by fermented soybean meal in (T1), fermented locust bean meal in (T2) and fermented melon seed meal in (T3) respectively were considered as experimental using a complete randomized design. Elephant grass (Pennisetum purpureum) was used as the basal diet and water were given ad libitum. There were significant difference in the final body weight gains (P<0.05) between treatments. The mean final body weights were 1175.0 ±302.01, 1266.7±302.01, 1215±302.01 and 1143.0±302.01g for animals on T0, T1, T2 and T3 respectively. The corresponding mean for final body weight gains were found to be 481±209.55, 536.7±209.55, 507±209.55 and 407±209.55g for T0, T1, T2 and T3 respectively. There were significant differences (P<0.05) in the trunk length in T1 over T2, T0 and T3 and were recorded at the level of4.78±0.19, 4.56 ±0.18, 4.55 ± 0.18 and 4.12 ± 0.16 respectively. The nutrient digestibility of CP, EE, NFE, ADF and ADL were significantly different (P<0.05). The whole cassava root that was combined with fermented soybean meal supported a highest growth rate than those of other treatments. It was therefore concluded that fermented soybean meal may be used as an ideal diet for sustainable Grasscutter production when whole cassava root is combined with this ingredient.J.
