This study was conducted to assess the growth performance, carcass traits and economics of production of broiler fed soya bean replaced with gliricidia sepium leaf meal diet. One hundred, 4 weeks old broiler chickens were randomly distributed to five treatments of two replicates with t10 birds per replicate. The birds were fed trial diets containing 0, 10, 20, 30 and 40% levels of soya bean replaced with G. sepium leaf meal for five weeks. Parameters measured included weight gain, weight of feed consumed, feed gain ratio, price per kg of feed, price per kg of broiler and weights of carcass parts among others. Data were analyzed using Analysis of Variance. Results showed that weight gain were not significantly influenced (P>0.05) by the dietary treatments. Feeding trial exerted effects on feed intake however, feed gain ratio and feed efficiency were not significantly different (P>0.05). No significant difference (P>0.05) was observed in thigh, wing and breast muscle weights of the birds fed G. sepium meal substituted diet however, liver weight was significantly affected by the diet. Price/kg of feed reduced with increased G. sepium in the diets but the cost per/kg animal produced was not significantly affected (P>0.05). It could therefore be suggested that soya bean meal could be replaced with G. sepium leaf meal up to 40% level without adverse effect on performance and weights of major primal parts of the bird. This will also reduce the cost of feed and competition for soya beans between man and livestock industry.

Feeding trial was conducted in 18 plastic tanks (60 x 45 x 30 cm) to assess the performance of Clarias gariepinus fingerlings fed diets containing fermented Mucuna pruriens leaf meal as an alternative protein source to soya bean meal. Five isonitrogenous (crude protein-40%) diets were formulated containing fermented Mucuna leaf meal (FMLM) at A(100% FMLM), B(75% FMLM), C(50% FMLM), D(25% FMLM) and E(0% FMLM) and were fed at 5% body weight to triplicate groups of 10 fingerlings (initial mean weight ranged from 6.20± 1.96g – 6.80± 1.97 g) of C. gariepinus for a period of twelve (12) weeks. Growth performance and feed utilisation parameters indicate that E(0% FMLM) diet gave the highest weight gain (168.87± 3.97g) but did not significantly (P≥0.05) differ from D(25% FMLM), (161.30±6.12 g), and the lowest weight gain (89.70± 1.96 g) was recorded in A(100% FMLM). Similarly, the highest specific growth rate (3.79±0.03 g) was recorded in E(0% FMLM)  followed by D(25% FMLM) (3.74±0.04 g), and the least value (3.10±0.02 g) was obtained in A(100% FMLM). However, feed conversion ratio (FCR), protein efficiency ratio (PER) and gross feed conversion efficiency (GFCE) were not significantly different (P≥0.05) among the dietary treatments. The highest (1.72±0.12) and least (1.50±0.02) FCR were obtained in A(100% FMLM) and E(0% FMLM) respectively. The result from this study indicates that fermented Mucuna  leaf meal could replace soya bean meal up to 25% in the diets for C. gariepinus fingerlings without compromising growth and feed utilisation.

  One hundred and twenty (120), 1 week old broiler chicken were randomly assigned to 4 treatment diets in a completely randomized experiment that lasted 49 days. The diets were made with soya bean based diet (D1) as control and treatment diets D2, D3, D4 containing graded levels (7.5%, 10%, 12.5%) of boiled Mucuna sloanei seed meal mix with  enzyme(BME).Birdsfed diet 2 (7.5% BME) had higher final body weight 2216.70g. The test diets gave lower total feed intake value that was significantly (P<0.05) lower than that of the control. D2 gave the lowestfeed-to-gain ratio (1.72) that was significantly (P<0.05) different fromthoseof the control(2.09), D3 (2.08)and D4 (2.27). There was no significant difference (P>0.05)among birds fed the treatmentdietsand thosefed the control diet for dressed weight percentage and back cut percentage. D2had cost/Kg weight gain and gross margin (N190.44 and N686.97 respectively) that were numerically higher than those of the control (N272.75 and N660.68) but statistically higher than those of, D3(N241.45 and N505.29) and D4 (N274.45 andN387.71). Mucuna seed meal mixed with enzyme in this experiment was 7.5% which performed better than the control in all the parameters considered and is therefore recommended for replacement of soya bean meal in the diet of broiler chickens.

Thirty-two yearling Friesian steers were used in a 2 × 2 factorial experiment. The treatment variables were source of supplementary nitrogen and physical form of the diet. The diets contained 30% ground barley straw, ground maize, a nitrogen supplement, and minerals and vitamins. Urea was compared with soya bean meal as the nitrogen supplement and both diets were given as cubes or meal. There was no significant difference between treatments in daily live-weight gain, feed intake or commercial carcass acceptability.Digestibility trials with wethers showed the apparent digestibility of nitrogen and dry matter of the diet containing urea to be significantly lower than that of the diet containing soya bean meal (nitrogen 72·8 ν. 76·3, P < 0·001; dry matter 70·2 ν. 75·3, P < 0·01). The results are discussed in relation to the digestibility of the diets used, the source of supplementary nitrogen and the physical form of the diet.

Considering the inherent attributes of processed African Yam bean meal (Sphenostylis stenocarpa), it's appropriate utilization for chicken diets may enhance performance of finisher broilers. The study was therefore carried out to determine the dietary substitution of soybean meal with processed African yam bean meal as protein source in the diets of finisher broilers. The Processed African yam bean meal was used to substitute soya bean meal at various levels to determine the best substitution that would give optimal performance in finisher broilers. The seeds of the African yam beans were soaked in water for 24 hours The soaked seeds were thereafter air dried for three days. The seeds were toasted for 35 minutes in a frying pan and milled using hammer mill. In the finisher feeding trial, the  substitutions were 20%, 40%, 60% and 80% processed African yam bean meal respectively. Each finisher diet was fed to a group of 30 broilers for 4 weeks using completely randomized design. Each treatment group was divided into 3 replicates of 10 broilers chicks each. The finisher broilerswere kept in pens in deep litter and given feed and water ad libitum. The parameters measured included initial body weight, final body weight, feed intake, body weight gain, feed conversion ratio, cost of production and carcass characteristics. The proximate composition of processed African yam bean meal showed that it contained 8.29% moisture, 91.71% Drymatter, 3.40% ash, 21.12% crude protein, 5% ether extract, 5.73% crude fiber and 56.4% nitrogen free extract. In the finisher feeding trial, the broiler group on 40% processed AYBM significantly (P<0.05) recorded higher body weight gain than the rest of the treatments possibly because of the proper substitution of soya bean meal with processed AYBM in their diets and it appeared that the finisher broilers could tolerate high levels of processed AYBM in their diets. The group on diet 2 (20% AYBM) and control diet recorded similar body weight gain (P>0.05) which were significantly (P<0.05) superior to the groups on diets 4 (60% AYBM) and 5(80% AYBM). The internal organs expressed as percent of the live weight were not affected by the treatments. Cost of production (cost/kg feed x feed conversion ratio) was lowest for diet 2 (N450.64) as against N480 for the control diet. The finisher broiler on diet 3 (40% AYBM) recorded the highest dressing out percentage of 78.78. The results of the trial have shown that processed African yam bean meal can be used to substitute soya bean mealin the diet up to 40% for optimum performance of the finisher broilers without affecting the body weight gain, feed intake, feed conversion ratio and carcass  characteristics as indicated in this study.

The growth performance of catfish Clarias gariepinus using imported feeds and locally made feeds of the same crude protein were compared. C. gariepinus (mean weight 12.8g) juvenile were reared in cages for a period of 12 weeks on different feed. Two imported feeds (skretting and copens) were purchased and two local feeds (corresponding to treatment) were compounded to contain the same level of crude protein. Locally ingredients used are maize, fish meal, groundnut cake, soya bean meal, bone meal, lysine, methionine, premix, vegetable oil, salt but varying fish meal and soya bean meal as follows, treatment 1- (11.38% to 7.5%), treatment 2-(7.5% to 11.38%) respectively. The pelleted feeds were fed at the rate of 5% of the fish biomass. The growth response was assessed in terms of daily weight gain, relative weight gain, specific growth rate, feed conversion ratio, mortality and survival rate. The results showed that the two local feeds promoted positive growth, implying that the use of different levels fish meal and soya bean meal (11.38% and 7.5%) favoured culture of juvenile C. gariepinus.Key Words, Clarias gariepinus, diet, fish feed, formulation, growth

SUMMARYTwo experiments were conducted with 84 male British Friesian calves to estimate their nitrogen and sulphur requirements between 5 and 11 weeks of age. A basal 12 % crude protein (CP) diet was supplemented with meat meal, soya bean meal or urea to 15 or 18 % CP, and with sulphur to reduce the nitrogen to sulphur ratios of the diets to about 10 to 1.The weight gains and feed conversion ratios of the calves given the 12% CP diets were significantly poorer than those of the calves fed on the diets containing 15 or 18% CP, irrespective of the CP supplement used. The supplementation of the urea-containing diets with sulphur caused a significant increase in feed intake and weight gain.The digestibility of nitrogen and dry matter increased with increasing CP content of the diets and was greater for the diets supplemented with urea than for those supplemented with meat meal or soya bean meal. Sulphur additions also increased the nitrogen digestibility. The retention of nitrogen, when corrected for feed intake, was greater in the calves fed on the diets containing 18% CP than in those fed on the 15% and 12% CP diets.The supplementation of the diets with sulphur increased the digestibility of sulphur, its excretion in urine and its retention. The concentration of urea in the blood plasma increased with increasing dietary CP content, and was higher in calves given urea.

In the first experiment, 250 unsexed day-old chickens were given for 7 days a diet low in vitamin A based on white maize and soya bean meal. Then 100 chickens were given a single dose of 11, 960 IU retinyl acetate or 11, 510 IU retinyl palmitate and 50 were not dosed. After 68 h lots of 10 pooled livers were analysed for vitamin A. The birds given acetate had more vitamin A in the liver and a higher proportion of the dose stored than the palmitate groups, but the differences were not significant. In experiment 2 the sexes were equally divided within groups and the birds were similarly dosed. After 72 h liver vitamin A was significantly higher in groups given the acetate. In experiment 3 male and female chickens were separated and groups of each were given either the acetate or the palmitate ester. Vitamin A was measured in the liver after 3 days and after 4, 6, 7 and 8 weeks. It was significantly more in acetate-treated groups at 3 days and at 4 weeks. Compared with males, females had significantly greater vitamin A stores at 6, 7 and 8 weeks in groups given acetate and at 7 weeks in groups given palmitate. The next experiment was similar, but the basal diet contained 7-5 IU retinyl acetate in dry stabilised form and measurements were continued to 9 and 11 weeks. There was no significant difference in vitamin A stores between sexes or esters, or between dosed and non-dosed groups. Stores of vitamin A rose rapidly during the entire period. In experiments 5 and 6 male broiler chickens were given for 8 weeks the basal diet with 7.5 IU retinyl acetate or palmitate per g. Lots of 3 different body-weight ranges were taken from each treatment and liver vitamin A was measured. No significant effects of treatment on stores or bodyweight were found in either trial. In one trial liver weights were significantly higher in the acetate groups and the combined results showed significantly greater vitamin A stores in groups given acetate.-G. F. H.
