The study was conducted to determine the effects of graded levels of teak (Tectona grandis) kernel meal on rabbits. Thirty weaned rabbits aged between 4 – 5 weeks old were which lasted for 12 weeks. The rabbits were randomly allotted to five dietary treatments of two replicates consisting of three rabbits each in a completely randomized design. The calyx layer of the kernel was removed via sieving and rubbing in-between the palms, and the middle layer coupled with the innermost layer were crushed and milled using huller mill to obtain teak kernel meal. Experimental diets were compounded in such a way that Diet 1 contained no teak kernel meal (control) while Diets 2, 3, 4 and 5 contained the test ingredient at 5, 10, 15 and 20% levels of inclusion respectively. Teak kernel meal was analysed for moisture, crude fibre(CF), crude protein (CP), ether extract (EE), ash and nitrogen free extract (NFE).The results for moisture, crude fibre, crude protein, ether extract, ash and nitrogen free extract were 7.36, 54.90, 8.75, 8.50, 5.00 and 16.88% respectively. Anti-nutritional factors were also analysed for oxalate, phytate, cyanide, tannin, flavonoid and alkanoid, and the results were 28.6mg, 3.65, 0.32, 2.35, 3.12 and 0.42% respectively. Rabbits fed Diet 1 had the highest final weight of 1635.88g while those fed Diet 5 exhibited the least (1411.20g). There were significant (P<0.05) differences among daily feed intake of the rabbits. The study suggests that rabbits can tolerate 20% of the test ingredient without any deleterious effect.

Mixture of bovine blood and rumen digesta (BBRDM) was evaluated for 56 days as a replacement for soybean meal (SBM) and groundnut cake (GNC) at 100% on protein to protein basis in the diets of growing pigs to assess the nutritive value of BBRDM on the growth performance, nutrient digestibility and cost benefits. Hence, a total of 18 growing pigs were allotted on weight equalization basis into three dietary treatments consisting of six pigs per treatment in a completely randomized design. Three diets were formulated such that T : served as the control diet without BBRDM but contained both soybean meal and 1 groundnut cake. T : BBRDM replaced soybean meal and T : BBRDM replaced groundnut 2 3 cake. Result indicated that BBRDM contained 28.65% crude protein, 13.17% ether extract, 5.26% crude fibre, 11.29% ash and 31.65% nitrogen free extract. Dietary treatments did not significantly (P>0.05) influenced the growth parameters observed in this study. Although there were no significant (P>0.05) difference on the nutrient digestibility parameters investigated but birds in T recorded highest numerical values for crude protein (77.23), 3 crude fibre (62.46%), ether extract (92.33%), nitrogen free extract (89.61%), ash (70.28%) and nutrient dry matter (91.67%) while the least values were obtained from birds in T . Cost 1 of feed decreased with the inclusion of BBRDM while the cost per weight gain also improved with the replacement of the conventional feed ingredients. The result also showed that an appreciable amount of money was saved when BBRDM was included in the ration of growing pigs. It is therefore concluded that BBRDM could be used as an animal protein source to compliment plant protein source such as soybean meal and groundnut cake in the diet of growing pigs.

Twelve ram lambs of the West African Forest type of between 15.7 and 24.6 kg were divided into four groups of 3 animals each. A group was assigned to one of four diets consisting of the following concentrate: grass hay ratios - 20 : 80 (A), 40 : 60 (B), 60 : 40 (C) and 80 : 20 (D). Feed intake, nutrient digestibilities and efficiency of feed utilization were measured. As the level of concentrate increased, the contents of crude protein ether extract, nitrogen-free extract (NFE) and gross energy of the diets increased, while the crude fibre and ash contents decreased almost linearly. Voluntary feed intake increased with increasing levels of concentrate, with diet C having a significantly higher (P 0.01) Relative Intake (RI) value than the other diets. Both the Nutritive Value Index (NVI) and Digestible Energy (DE) intake values were significantly higher (P. 0.01) in diets C and D than the other diets. Generally, the digestion coefficients for the gross energy, crude protein, crude fibre and nitrogen free extract increased with increasing levels of concentrate, the values being significantly higher (P 0.01) in diets C and D, while diet A showed a significantly lower (P 0.05) dry matter digestion coefficient value when compared with either diets. Although a similar trend was observed in the digestion coefficient for ether extract, the differences were not significant (P 0.05). With the exception of animals on diet C which had the highest daily weight gains, average daily weight gains and efficiency of feed utilization increased with successive substitution of concentrate for grass hay.

Nulliparous crossbred does were used to study the effects of concentrate:lablab ratio (CL) and stage of pregnancy on nutrient intake and digestibility. Treatments consisted of four concentrate and lablab combinations on a gram:gram basis: 20:130, 40: 110, 80:70 and 100:50 and two stages of pregnancy: second and fourth week of pregnancy Concentrate intake increased as level increased up to 80g/day offered while lablab intake increased from 50 to 130g/day offered. Doe weight and metabolic size were similar for all treatments. Total feed intake was not affected by concentrate and lablab levels. Dry matter intake was lower for 100:50 CL than other treatments. Ether extract and crude fibre intakes decreased with increase in concentrate levels. Dry matter and nitrogen free extract digestibility were higher for 80:70 CL than other combinations. Crude fibre digestibility was higher for 80:70 than 40:110 and 100:50 CL Crude protein retention was higher for 80:70 than 20:130 and 100:50 CL. Fetal growth requirement, total protein requirement and balance of protein were high at 80:70 and 100:50 CL. During pregnancy, dry matter and all nutrients intake were higher in the second than fourth week. Ether extract, crude protein and nitrogen free extract digestibilities were lower in the second than fourth week of pregnancy. Fetal growth requirement and balance of protein were higher in the second than fourth week of pregnancy relationship between feed intake (g DM/day) and nutrient digestibility was negative. The relationship between feed intake (g DM/kg body weight/day) and feed intake (g DM/kg LW0.75/day) was however, positive for all the nutrients except crude protein. For the small scale rabbit producer in developing countries, it is feasible to maintain rabbits on combinations of concentrate and lablab during pregnancy

The potential of sugarcane peels as a substitute for maize offal in rabbit diets and its effect on growth, nutrient digestibility, and carcass characteristics were studied. Twenty five growing rabbits of mixed breeds and average body weight of 894±26.14g were used in a 7-week feeding trial. Five experimental diets were formulated in which sugarcane rind (SCR) was included at 0, 10, 20, 30 and 40% level to replace maize offal (weight for weight). The rabbits were balanced for weight and allotted to the treatments (n=5 rabbits/treatment) in a completely randomized design. Results obtained indicated that dry matter, crude protein, ether extract, nitrogen free extract, hemicellulose, acid and neutral detergent fibre intake and digestibility decreased with increasing level of sugarcane rind inclusion. Crude fibre intake (5.59-8.67 g/day) and digestibility (20.60-40.80%) however increased (P<0.05) as level of sugarcane rind increased in the diet. The 30% inclusion of sugarcane rind gave body weight gain (5.35 g/d) comparable to the control (6.41 g/d), 10 (7.78 g/d) and 20% (7.12 g/d) inclusion of sugarcane peels. Feed intake (44.61-40.59 g/d) decreased as the level of sugarcane rind increased in the diets. There was no significant (P>0.05) effect of sugarcane rind on metabolic body weight and feed efficiency. Inclusion of sugarcane rind at 30% level increased (P<0.05) thigh and head percentage but without any adverse effect on chest, loin, shoulder and skin. Based on the results, it is concluded that sugarcane rind is a good fibre source that can be used to replace maize offal up to 30% in rabbit diets.

The effects of different dietary levels of toasted bambara groundnut (Voandzeia subterranea L) waste on the performance of growing rabbits was studied. Twenty-four, 6-7 weeks old cross bred (Chinchilla x New Zealand whitel rabbits with average initial weight of 9629 were used for the feeding trial which lasted for 8 weeks. The rabbits were randomly divided into four treatment groups of 6 rabbits each and fed diets containing 0% (control), 10, 20 and 30% toasted bambara groundnut waste (TBGW) using a completely randomized design (CRD). Dry matter, crude protein, crude fibre, ether extract and nitrogen-free extract intake and digestibility, weight gain and economics of TBGW inclusion were determined. Proximate composition of the diets, faeces, raw and toasted samples were also determined. The raw and toasted bambara groundnut waste had 91 and 93% dry matter, 17.0 and 16.27% crude protein, 26 und 24% crude fibre, 5 and 3. 5% ether extract, 2.5 and 4.0% ash, 40.5 and 45.23% nitrogen-free extract, and 4.13 and 3.88 kcal/g energy respectively. Significant differences (P<0.05) existed between treatments in feed intake, weight gain, final body weight, and digestibility of dry matter. crude protein, crude fibre and nitrogen free extract. Feed intake, weight gain, final body weight, and digestibility of dry matter, crude protein and nitrogen-free extract were similar for the control and 30% TBGW diets, and these were significantly (P<0.05) lower than that for 10% TBGW diet. The feed cost AN/kg gain) was similar for 10, 20 and 30% TBGW diets. The result showed that up to 30% toasted bambara groundnut waste can be included in the diets of growing rabbits without any adverse effect on performance.

A study was carried out to determine the chemical composition of roselle seeds fermented at varying durations. One kg cleaned Roselle seeds were soaked in 3L of water for 8 hours. The soaked seeds were drained and fermented for 0, 24, 48, 72 and 96 hours as treatments. Samples of fermented roselle seeds at different duration of fermentations were analyzed for chemical composition including anti-nutritional factors. The results showed that there was significant (P<0.05) effect of fermentation duration on chemical composition and antinutritional factors of roselle seeds. Dry matter and crude protein content increased as fermentation duration increased from 0 to 96 hours. The highest dry matter (91.87%) and crude protein (35.05%) were obtained at 96 hours while crude fibre and ether extract decreased with increased fermentation duration. Crude fibre (6.55%) and ether extract (26.79%) were highest at 0 hours. Ash and nitrogen free extract content ranged from 5.41 – 5.78 % and 30.62 – 39.19 %, respectively. Anti-nutritional factor contents declined withincreased fermentation duration. The lowest values for saponin (2.02%), tannin (0.15%), phytic acid (5.44%) and trypsin inhibitor (8.93%) were obtained at 96 hours fermentation. It can be concluded that roselle seeds fermented for 96 hours enhanced nutrient availability and significantly reduced tannin, phytate, saponin and trypsin inhibitor anti-nutritional factors.

The bagasse has potential as an alternative feed for ruminant. However,  though the high of the crude fibre and the very low in the nutritional value make them very limited in using for animal feed. To overcome the problem in order to increase nutritional value was the fermentation technology by the application of the starbio inoculums. The objective of the research was to observe the  nutrition  qualities of the bagasse with aplication of different levels of starbio. The experimental design was  a completely Randomized Design  with 4 treatments i.e. P0 (bagasse + 0% Starbio), P1 (bagasse+ 0.2% starbio), P2 (bagasse+ 0.4% Starbio), P3 (bagasse+ 0.6% Starbio) and each treatment has 5 replication, The parameters measured were pH, dry matter (DM), crude protein (CP), ether extract (EE) crude fiber (CF), ash and Nitrogen Free Extract (NFE). The results of the research indicated that pH of the  fermentation was very good (3.37-3.67), DM (66.59-68.73%), and CP 1.47-1,97%. However, there was no effect on EE, CF, ashes and NFE. The addition of 0.6% starbio was the best result to increase CP but did not affect on ash content.

SUMMARYEighteen individual feedstuffs and 19 mixed diets were used in a study attempted to relate determined energy values to various chemically determined measures. For cereals the level of fibre could be used to predict digestible and metabolizable energy (DE and ME). In the case of DE the relationships with crude fibre and modified acid detergent fibre (MADF) based on 14 feeds were:DE (kcal/kg D.M.) = 4179–86 MADF (%): r =–0·96; P < 0·01,DE (kcal/kg D.M.) = 4228–140 x crude fibre (%): r =–0·97; P < 0·01.For all feeds the following equations gave the best prediction of energy values from dietary analysis (on the basis of correlation coefficients and residual standard deviations):DE (kcal/kg D.M.) = 109·9 x crude protein (%) + 149·3 x acid ether extract (%) + 90·1 x nitrogen-free extract (%)–5030: R = 0·95; P < 0.01.ME (kcal/kg D.M.) = 99·5 x crude protein (%) + 144·7 x acid ether extract (%) + 87·8 x nitrogen-free extract (%)–4795: R = 0·94; P < 0·01.Digestible nutrients were closely related to DE and ME, e.g.DE (kcal/kg D.M.) = 52·9 x digestible crude protein (%) + 108·3 x digestible ether extract (%) + 39·4 x digestible crude fibre (%) + 39·9 x digestible nitrogen-free extract (%) + 183·7: R = 0·99; P < 0·01.
