Two experiments consisting of three dietary treatments each were conducted on the use of crop residues and agro-industrial wastes for formulating complete diets for growing West production. African dwarf sheep and goats. Growth Performance and digestibility studies were carried out with the animals, In experiment  Crude protein (CP), ash and gross energy levels increased from diet 1 to diet 3 while the crude fibre contents decreased progressively. Sheep consumed more nutrients (P<0.01) than goats. In the streep, the highest dry matter intake (DMI) was on diet 2 (74.1y/kyw 0.75). However,the intakes of CP and energy on diets 2 and 3 d were similar (P1.05). Energy intake was highest in diet 3 for goats, while DMI (47.6g/kW0.75 .) was comparable (P>0.05) to those on diets 1and 2 (50.5 and 45.0y/kyW0.75 respectively. Various strategies Sheep and goats digested DM, CP and energy similarly (P>0.05). Diet 3 was the most digestible (P<0.01) for energy in both species. Digestibility of DM and CP was best in diet 3 for sheep. The highest (P<0.05) weight gain of 60.3y/day was for sheep on diet 3. The best feed conversion efficiency (FCE) was also recorded for the same diet for sheep (10.0%) and goat (9.2%). In Experiment 2, crude protein levels fibre decreased from diets 1 to 3. Concentrations of HCN (16.7 and 19.3mg/kgfor primary diets 1 and 2 respectively) were low. Sheep consumed more (P<0.05) DM than goats (83.8 and 79.5g/kg w respectively) while CP was consumed similarly (P>0.05), Goats digested DM (68.2% better (P<0.05) than sheep (59.6%). Diets did not influence (P>0.05) the DM digestibility within the two species. The highest (P<0.05) weight changes were recorded on diet in 3 for sheep and goats (112.4 and 55.2g/dey

The objective of this work was to determine the proper levels of protein and energy in diets of Hoplias lacerdae fingerlings. The dietary crude protein (CP) and gross energy (GE) levels for fingerlings of giant trahira were evaluated in a completely randomized 4x3 factorial design with 35, 39, 43 and 47% CP and 4,100, 4,300 and 4,500 kcal kg-1 of GE, and four replicates. The survival rate was 99.22%, and a linear improvement on the performance parameters was detected after increasing diet crude protein levels. Feed conversion ratio decreased with increasing levels of dietary protein and energy in the diets. A significant interaction between crude protein and gross energy was observed over body protein and mineral matter. Body lipid has increased linearly as gross energy in the diet increased. The retention of crude protein and energy showed a linear increasing with rising of crude protein levels in the diet. Crude protein level at 47% provides the best performance and energy retention, independently of the gross energy levels in the diet.

This paper aims at investigating relationships and effects of varying protein and energy levels on growth performance, efficiency of feed conversion and efficiency of nutrient utilization of weanling pigs fed from of 9 to 60kg. A total of one hundred and twenty weanling pigs weighing ± 9kg were allotted randomly to sixteen groups of eight pigs each. for females and four castrated males in a 4x 4factorial design. The sixteen diets consist of four digestible energy levels (3,000: 3300: 3,600 and 3,900 kcal/kg) and four crude protein levels (18; 21: 24 and 27%). The pigs were fed these experimental diets until they attained a predetermined liveweight of 60 +1.5 kg. The effects of the varying crude protein and digestible energy were studied on growth and performance parameters Neither protein nor energy levels significantly affected daily feed intake, but significantly decreased daily feed intake at 27protein level. Daily protein intake was influenced by protein intake and digestible energy intake was also significantly influenced by digestible energy intake. There were no significant interactions between protein and energy levels with respect to feed intake and intake of protein and energy Energy but no protein levels significantly influenced rate of live weight gain. Feed conversion efficiency (FEC) was highly (P 0.001) influenced by energy but not protein levels. In both sexes, females and castrated males, increasing dietary levels of protein and energy resulted in improved efficiency of feed utilization within protein levels but there were significant differences between the two highest energy levels for castrated males and within the diets with 3.300, 3.600 and 3.900 kcal/DE/kg for the females. When high protein levels were combined with high energy levels feed intakes were depressed only on the 279% protein level. Feed conversion efficiency was maximized on the diet with 21 and 249% protein levels with appreciable sex diferences, with female pigs requiring more protein than males. Digestible Energy range of 3,300 and 3,600 kcalkg would be adequate for maximum gain and efficiency of feed utilization in pigs under the humid tropical environment tropical. Feed to gain ratio, a very important economic index should be an important index of the quality of any diet for promoting growth.

THE effect on body weight changes of sheep and goats and digestibility of maintenance rations in which cocoa husk constituted, 0%, 20%, 40% and 50% of the basal ration respectively were studied. These rations were fed to wethers and castrated goats in separate but concurrent digestibility trials. There was no significant change in body weight of both the sheep and the goat. Significant decreases in apparent digestibility occurred in dry matter, organic matter, crude protein, crude fibre and total digestible nutrients. The 40% cocoa husk ration in which cocoa husk existed with maize in the ratio 2:1 appeared to be next best to the control ration for fibre digestibility. Apparent digestibility of the crude fibre component of the feed was significantly higher in the sheep than in the goats.

The objective of this study was to determine the crude protein requirements for juvenile jundiara fish, a hybrid of Pseudoplatystoma fasciatum X Leiarius marmoratus. A total of 240 juveniles of the hybrid, with an initial mean weight of 8.4 ± 1.41 g, were distributed in 15 fiberglass tanks (170 L) in a closed water recirculation and constant aeration system, with a density of 16 fish/tank. The experimental design was completely randomized with five treatments and three replications. The treatments consisted of diets with 32, 34, 36, 38 and 40% crude protein. Seventy days into the experiment the final fish weight and feed intake were measured. Two specimens from each experimental unit were collected for evaluation of carcass chemical composition, nutritional efficiency and blood parameters. The increase in crude protein content promoted the significant, increasing linear effect for mean weight gain, mean feed intake and specific growth rate, and decreasing effect for feed conversion. Significant differences were also observed in carcass chemical composition, nutritional efficiency, total plasma protein, glucose, cholesterol, triglycerides and lipase enzymatic activity. Thus, the increase in crude protein levels of up to 40% in jundiara diets promotes improvement in the productive performance of juvenile jundiara.

Abstract The purpose of the study was to obtain preliminary data on the effect of dietary protein on the growth of the thick-lipped grey mullet (Chelon labrosus) juveniles reared in net sea-cages. The juveniles (6.2 ± 0.61 g) were obtained from the wild and were stocked into net sea-cages at a stocking rate of 100 juveniles per cubic meter and fed with experimental diets including 25, 30, or 35% crude protein for 87 days. The highest mean weight and specific growth rate (SGR) were 39.5 g and 2.13% day−1, respectively, at protein levels of 30%. The diet also resulted in the most efficient feed conversion ratio of 1.61.

The aim of this study was to evaluate the growth of and feed utilization by Boer x Kacang crosses goats fed on total mixed ration differing in protein and energy levels. Four total mixed rations combination were formulated to contain 16 and 18% crude protein and 2650 and 2850 Kcal ME/ kg DM (dried matter) energy density. Twenty-eight male Boer x Kacang crosses goats (14.5 ± 1.14 kg) and of age ranging from 4 to 5 months were randomly allocated to one of these four TMRs (total mixed rations) (7 animals/TMR). The effects of dietary treatment were assessed using the general linear model and significance of the diet effects was detected using Duncan’s multiple range test. Dry matter intake increased as metabolizable energy density of diet increased from 2650 to 2850 Kcal/kg DM, but it is not affected by increasing crude protein level from 16 to 18%. The average daily gains were not improved (P&gt;0.05) as the crude protein levels and metabolizable energy density of diet increased. Crude protein levels and ME density did not affect (P&gt;0.05) the DM, OM and energy digestibility, but NDF digestibility was affected by the ME density of diets (P&lt;0.05). Daily N intakes were greater (P&lt;0.0%) in goats received diets higher in the crude protein and metabolizable energy levels. At this high rate of feed intake this type of goats are able to gain optimally when offered feed with crude protein level of 16% and metabolizable energy density of 2850 Kcal/kg DM.

As part of the search for alternative sources of food to alleviate hunger, this study reports the approximate total contents of soluble sugars, starch, and gross energy of nine lesser-known wild-gathered plant seeds. High crude protein levels occurred in Lonchocarpus sericeus (28.03%), Albizia zygia (32.90%), and Gliricidia septum (34.15%). High levels of fat occurred in Entandrophragma angolense (59.30%), L. sericeus (34.15%), and Millettia thonningii (30.66%). Low levels of crude protein but high levels of total carbohydrate were found in Diospyros mespiliformis (77.21% carbohydrate), Daneillia ogea (74.32% carbohydrate), and Afzelia belle (53.96% carbohydrate). Starch contents were high in A. zygia (40.46%), D. ogea (69.62%), and A. belle (51.43%). The seeds with high fat content invariably showed high gross energy levels: E. angolense (30.9 kJ/g), L. sericeus (24.37 kJ/g), and M. thonningii (25.12 kJ/g). The results are compared to those for soya bean and other common staples. It is concluded that these less familiar wild seed plants should not be ignored, but further investigation into possible toxic and antinutrient factors, amino acid patterns, digestibility, and fatty acid composition is still required before recommendations are made.

This study was conducted to evaluate the suitability of soaked <em>Bauhinia monandra</em> (Kutz) seed as alternative protein source for <em>Clarias gariepinus</em> and to determine cost of feed compounded. The proximate analysis of the diet (crude protein, crude fibre, ash, moisture content and lipid) were determined using AOAC (1980). Data for each parameter was subjected to one way analysis of variance (ANOVA) while means of various results were compared at 5% level of significance. A preliminary study was conducted to determine the best processing method that reduced anti-nutrients to the minimum level without impairing nutrients composition. Boiled, toasted and soaked seeds were used. <em>Bauhinia</em> seeds soaked for 96 hours had least concentration of anti-nutrients. The experimental diets was formulated to contain soaked <em>Bauhinia</em> seed meal (SBSM) at levels of 25%, 50% and 75% inclusion (Diets 2, 3 and 4 respectively)  with two diets acting as control (Diets 1 and 5). All diets were isonitrogenous (40% crude protein) and isocaloric (3212kcal/kg). A 12 weeks feeding trial was conducted using juveniles which were randomly distributed into 12 improvised non-recirculatory and semi-flow through indoor plastic tanks (52cm X 34cm X 33.5cm) at a stocking rate of 10 fish per tank and three (3) replicates per treatment. The experimental design was complete randomized. The fish were fed at 5% body weight, twice daily. Diets with higher inclusion levels of SBSM (diets 3 and 4) significantly depressed growth performance of fish. The variations observed in the Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), Feed Efficiency Ratio (FER) and Protein Efficiency Ratio (PER) were associated with the anti-nutrients present in the diets, these parameters reduced with increasing levels of SBSM in the diets of fish. Based on the relative cost of diets per unit weight gain and protein gain, diet 2 (25% SBSM) was most economical. The results suggested that SBSM can be used to substitute up to 25% levels of dietary protein in <em>C. gariepinus</em> juveniles without significant reduction in growth.

SUMMARYSixty-four young male Sudan desert lambs were group-fed for 87 days on four diets, all containing approximately 10% crude protein. The four diets contained 0, 1·3, 1·7 and 2·7% urea, respectively.Average daily gains were 0·15, 0·14, 0·14 and 0·13 kg; feed conversion ratios (kg of feed required to produce 1 kg live-weight gain) were 7·26, 8·14, 8·92 and 7·92; dressing percentages were 43·6, 42·1, 44·1 and 42·3.Digestibility trials with lambs fed on diets with 0 or 2·7% urea gave higher digestibility coefficients for crude fibre and nitrogen-free extract for the urea-supplemented lambs. Crude protein digestibility and nitrogen retention values were lower for urea-supplemented lambs.
