One hundred and fifty (150)day-old Abor acre broiler chicks were used for this experiment toassess growth performance and carcass characteristics of broilers fed processed roselle (Hibiscus sabdariffa) seed meal were investigated. The birds were randomly assigned to five dietary treatments with three replicates (ten chicks per replicate)each in a completely randomized design (CRD). In the feeding trial, raw roselle seed meal (R RSM), roasted roselle seed meal (R RSM), boiled roselle seed meal (BRSM) and soaked roselle seed meal (SRSM) were incorporated as part replacement for groundnut cake at 50% level of inclusion.Proximate composition of the processed test ingredients and the results showed that there were no significant (P>0.05) differences among the treatment means. Raw roselle seed meal (RaRSM) gave the least crude protein while the highest was recorded in boiled roselle seed meal (BRSM). Birds fed diet without roselle seed meal inclusion (control diet) had the best final body weight and feed conversion ratio but not significantly (P>0.05) different from other treatments.Birds in treatments 2 and 4 (RaRSMand BRSM) had the least survival rate (96.67%)while the rest treatments had 100%. Cut-up parts showed no significant (P>0.05) differences exceptfor the wings of the bird fed roasted roselle seedmeal was significantly (P<0.05) different and higher than those fed control, raw, boiled and soaked roselle seed meal (10.87, 7.52, 9.85 and 9.46%, respectively). Results from visceral organs showed no significant (P>0.05) differencesexceptproventriculus which exhibited significant (P<0.05) differences among the treatment means. Proventriculus of bird fed roasted roselle seedmeal (R RSM)was highest (0.80%)while those fed raw roselle seedmeal (R RSM) gave the least (0.50%). This study however, revealed that using processed (roasted, boiled and soaked) roselle (Hibiscus sabdariffa) seed meal as part replacement for groundnut cake has no deleterious effects onthe broilerchickens.

Randomized Design

Growth performance, carcass characteristics and economics of broiler chicken fed graded levels of raw Mucuna sloanei seed meal were investigated. A total of 150, 1- day old broiler chickens were used. There were five treatments each replicated into three with 10 birds per replicate in a completely randomized design. Five treatment diets were formulated. Diet 1served as control, while diets 2, 3, 4, and 5 had 5, 10, 15, and 20 %, respectively of raw mucuna seed meals (RMSM) added to them. The experiment lasted 49 days. The parameters considered were growth performance, carcass characteristics and economics of production. For growth performance, the result revealed that RMSM significantly (P<0.05) depressed growth as the levels of inclusion of RMSM increased from 0 to 20%. There were significant differences (p<0.05) in all the parameters considered under growth except for initial body weight and mortality. There was progressive loss in final body weight as the level of mucuna inclusion increased from 0% to 20%. Control recorded the highest live body weight of 3023.30g while, birds fed diet with 20% mucuna had the least body weight of 504.43g. Among the birds placed on the test diets, birds fed diet with 5% mucuna seed meal performed significantly (P<0.05) better (1840.00g) than other test diets. Birds fed diets with 10 and 15% mucuna had final body weight of 1180.00 and 726.67g, respectively. The progressive l oss in weight was obvious early in the experiment and at 8 weeks of age the broiler fed 20% raw mucuna. Mucuna sloanei based diet weighed only 504.43g (16.68% of the control) as against 1840.00, (60.86% of the control) for that fed 5%.mucuna. Percentage dressed weight and percentage breast and thigh were significantly (P<0.05) higher for chicken fed control diet. 10% level of raw MSSM gave highest value for drumstick (14.91%) while control gave the least (13.00%). 5% raw MSSM (27. 71%) compared favourably with control (30.60%) for breast cut. Gross margin significantly decreased from N1459.80 for control diet to N 14.20 for D5 as the percentage inclusion of MSSM increases from 0 to 20%. In conclusion, birds fed raw Mucuna sloanei seed meal diet could not compare favourably with those fed soya bean based diets even at 5% level of inclusion. Processing is therefore recommended to enhance performance.

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.

Pharmacologically Active

AbstractSalbutamol (albuterol) is a β-adrenergic agonist marketed as a racemic (50: 50) mixture of R- and S-enantiomers (rac-salbutamol). Since only R-salbutamol is pharmacologically active and S-salbutamol has a longer half-life in humans, we examined R-salbutamol as a performance enhancer and repartitioning agent in domestic chickens. The effects of feeding diets containing R-salbutamol (5, 10 and 15 mg/kg diet) and rac-salbutamol (10 mg/kg diet) from day 21 to 42 post hatching on growth performance, carcass characteristics and tissue concentrations of R- and S-salbutamol in male and female broilers were compared with a control diet. R-salbutamol in the diet lowered the weight gains in both sexes, but the magnitude of reduction was greater in males as indicated by a significant R-salbutamol ✕ gender interaction. R-salbutamol also lowered food intake and improved food conversion ratios in both sexes. The relative weights of breast muscle and leg muscle were significantly increased and the relative weight of the fat pad was significantly decreased in birds of both sexes given diets containing R-salbutamol. Carcass protein content increased and carcass fat content decreased but the differences were not statistically significant. A significant dose-response effect was observed for tissue concentrations of R-salbutamol in all tissues, except the fat. Performance and carcass parameters in chickens given the 5 mg/kg R-salbutamol diet were similar to those given the 10 mg/kg rac-salbutamol diet, but tissue concentrations of R-salbutamol were lower. Chickens given the 10 mg/ kg rac-salbutamol diet had higher tissue concentrations of salbutamol than chickens given the 10 mg/kg R-salbutamol diet and higher concentrations of S-salbutamol than R-salbutamol in liver and leg muscle. Overall, these results demonstrate that R-salbutamol is an effective repartitioning agent in broiler chickens.
