In a six-week feeding trial, a total of 48 crossbred weaned male rabbits of 7 weeks old were randomly allotted to four dietary treatments, with 12 replicates per treatment to determine growth indices and nutrient digestibility of rabbits fed fumonisin-contaminated diets. Maize grains contaminated with fumonisin B1 were incorporated into rabbit diets excluding the control diet (treatment 1, 0.13mgKg-1), at varied inclusion levels of 5.0mgKg-1, 7.5mgKg-1 and 10.0mgKg-1 fumonisin B1, constituting treatments 2, 3 and 4 respectively. The results showed that the average final live weight of rabbits fed treatments 3 and 4 were significantly (P<0.05) lower than those fed treatment 2 and the control. The average daily dry matter intake of the animals fed the dietary treatments was not significantly different. The mean daily weight gain of rabbits fed 5.0mgkg-1, 7.5mgKg-1 and 10.0mgKg-1 however declined significantly (P<0.05) by 91.23, 83.92 and 81.88% respectively, relative to the mean daily weight gain of 12.31g/rabbit/day of animals fed the control diet. The result further showed that digestibility of the nutrients of the experimental diets except crude protein, were similar among the treatments. The crude protein digestibility of rabbits fed 7.5mgKg-1and 10.0mgKg-1 were identical but significantly (P<0.05) lower than those fed 5.0mgKg-1 and the control diet. This suggests inhibition of nitrogen utilization and depressed performance in the animals fed diets containing ≥ 5.0mg fumonisin B1/Kg. Diets containing up to 7.5 mg fumonisin B1/Kg will depress live weight and daily weight gain as a result of reduced protein utilization in weaned rabbits.

Sweet Potato Vine

The study was carried out to determine the feed value of replacing maize with graded levels of sweet potato vine – cassava composite meal (SPV-CCM) to rabbits. Five treatment diets were formulated to contain SPV-CCM inclusion levels of 0% (control), 25%, 50%, 75% and 100%. Thirty weaned rabbits of mixed breeds and sexes were used for the experiment. They were randomly allocated to five dietary treatments with one rabbit as a replicate in a completely randomized design. Feed and water were provided ad libitum. Parameters measured were that of growth, digestibility, carcass and economics of production. The result showed that there was no significant (P>0.05) difference effect on final weight, total weight gain, daily weight gain and feed conversion ratio across the dietary treatments. There was no significant (P>0.05) difference on crude protein digestibility, crude fibre and ether extract which were within the required values for rabbit. There was no significant (P>0.05) difference on live weight at slaughter, dressing percentage, heart, liver, kidney, lungs/trachea, esophagus, stomach, small intestine, caecum, large intestine and visceral fat, there was however, a significant (P<0.05) difference in dressed weight, pancreases, spleen and kidney fat. A high cost of feeding, cost per kilogram diet and production was recorded in T and low cost of feeding, cost per kilogram diet and production in T . The result showed that 1 5 maize could be replaced by SPV-CCM up to 100% without any adverse effect on their performance, nutrient digestibility and carcass characteristics. However, the optimum performance was observed when 75% SPV-CCM replaced maize in the diet. Replacement of maize with SPV-CCM has relative cost advantage over the control diet and so should be incorporated in the diet of rabbit up to the level considered in this study.

The study investigated gut ecology and morphology of the Indonesian indigenous crossbred chickens (IICC) supplemented with the combination of formic acid and Saccharomyces cerevisiae. Two hundreds day-old IICC were distributed to T0 (control diet), T1 (T0 + 0.2% formic acid), T2 (T0 + 0.3% S. cerevisiae), T3 (T0 + 0.2% formic acid and 0.3% S. cerevisiae). Excreta was collected at week 8, while intestinal ecology and morphology were determined at week 9. In duodenum, T3 chicks showed higher and wider (P<0.05) villi. The T2 and T3 chicks showed deeper (P<0.05) crypt than that of T0. The jejunal villi was higher (P<0.05) in T3 than in T0. The T3 chicks had deeper (P<0.05) crypt compared to other groups. In ileum, the villi height was lowest (P<0.05) in T0. The crypt was deeper (P<0.05) in T3 than in other. Crude protein digestibility coefficient was highest (P<0.05), while fecal protein was loswest (P<0.05) in T1 than in other groups. Compared to T0, the treated IICC showed higher (P<0.05) weight gain and feed intake with T3 had the highest gain and intake but gain:feed rasio was the lowest (P>0.05). IIn conclusion, the inclusion of formic acid and S. cerevisiae in diets improved intestinal ecology and morphology. The IICC chickens fed with formic acid and S. cerevisiae exhibited improved growth performance and nutrient digestibility.

A study was conducted for eight weeks to determine the effects of raw and cooked mucuna seed meal (MSM) based diets on the performance and haematological characteristics of cross-bred weaned rabbits. Three experimental diets were formulated to contain: 0% MSM (control diet A), X raw MSM (diet B) and 20% cooked MSM (diet C). Twelve cross-bred weaned rabbits with mean initial live-weight of about 550 g were randomly assigned to three dietary treatments. The experimental design was completely randomized arrangement. The feed intakes (115.12, 114.44, 116.15g/day) and weight gains (17.19, 12.72, 14.28g/day) for diets A, B and C respectively were similar (P>0.05) for the three treatments. Rabbits fed the control diet A had the best (P<0.05) feed conversion ratio (6.68). The packed cell volume (PCV), haemoglobin (HB), red blood cell (RBC) and white blood cell (WBC) values obtained for the three treatments were not statistically different (P>0.05) from one another. The HB, RBC, WBC values of rabbits fed on 20% cooked MSM based diet had comparable values to those on the control diet. Based on the weight gain and the haematology, 20% cooked mucuna seed meal can be included in the diet of weaned rabbits.

A 42-days trial was conducted to investigate the effect of caecotrophy on performance, apparent nutrient digestibility and blood parameters in growing rabbits. Thirty-six cross- bred rabbits with an average initial weight of 875±25 g were divided into 2 groups (collared and uncollared). The collared group was prevented access to their caecotropes (soft faeces) while the uncollared group were allowed access. Each group had 18 animals with 3 growing rabbits per group, replicated 6 times in a completely randomised design (CRD). The result of the study showed that the uncollared group had higher (P<0.05) final live weight, daily weight gain, feed intake which were, 1.76 kg, 17.00 g/day, 50.6 g/day, respectively when compared with the collared group which recorded 1.53 kg, 11.7 g/day and 41.7 g/day respectively. Also, lower (P<0.05) values were recorded for feed conversion ratio and mortality in uncollared rabbits in comparison to their collared counterparts. The ash and crude protein digestibility were higher (P<0.05) in the uncollared group. Serum total protein and albumin were higher in uncollared group while globulin was higher in collared group while Urea and AST was lower in uncollared group. Haematological parameters were not affected by caecotrophy. It can be concluded that prevention of caecotrophy has detrimental effect on the performance, nutrient digestibility and serum biochemical parameters of growing rabbits     Un essai de 42 jours a été mené pour étudier l'effet de la caecotrophie sur la performance, la digestibilité apparente des nutriments et les paramètres sanguins chez les lapins en croissance. Trente-six lapins croisés d'un poids initial moyen de 875±25 g ont été divisés en 2 groupes (à collier et non-collier). Le groupe à collier a été empêché d'accéder à leurs caecotropes (excréments mous) tandis que le groupe non collier a été autorisé à y accéder. Chaque groupe avait 18 animaux avec 3 lapins en croissance par groupe, répliqués 6 fois dans un design complètement randomisé (CRD). Le résultat de l'étude a montré que le groupe non collier avait un poids réel final plus élevé (P<0.05), un gain de poids quotidien, une consommation d'aliments qui étaient de 1.76 kg, 17.00 g/jour, 50.6 g/jour, respectivement par rapport au groupe à collier qui enregistrait respectivement 1.53 kg, 11.7 g/jour et 41.7 g/jour. De plus, des valeurs inférieures (P<0.05) ont été enregistrées pour le ratio de conversion des aliments et la mortalité chez les lapins noncollier par rapport à leurs homologues à collier. La digestibilité des cendres et des protéines brutes était plus élevée (P<0.05) dans le groupe noncollared. La protéine totale de sérum et l'albumine étaient plus élevées dans le groupe noncollier tandis que la globulin était plus élevée dans le groupe collier tandis que l'urée et l'AST étaient plus bas dans le groupe noncollier. Les paramètres hématologiques n'ont pas été affectés par la caecotrophie. On peut conclure que la prévention de la caecotrophie a un effet néfaste sur la performance, la digestibilité des nutriments et les paramètres biochimiques sériques des lapins en croissance

This study examined the nutritional value of Mulberry leaf meal (MLM) as substitute for soybean meal (SBM) at graded levels. Forty cross-bred young rabbits of mixed sexes used for the study were purchased from a reputable farm in Osogbo, Osun State, Nigeria. The animals were balanced for the initial weight and randomly allocated to five experimental dietary treatments of 8 rabbits per treatment. There were 4 replicates of 2 rabbits per replicate. The rabbits were provided with pelletized experimental diets and clean water ad libitum for 2 weeks pre-experimental period and thereafter for 8 weeks during which data were collected. Five (5) diets containing 0 (0.00% MLM, control), 25 (1.25% MLM), 50 (2.50% MLM), 75 (3.75% MLM) and 100% (5.00% MLM) as replacement for SBM were formulated and contained ME ranging from 2617 – 2661 kcal/kg and crude protein ranging from 15.01 – 16.00%. The average daily weight gain (8.71 g/R/d) obtained in control was similar to 8.03 g/R/d (25.00% MLM), and both significantly (P < 0.05) reduced to 6.75 g/R/d (50.00% MLM), 6.73 g/R/d (75.00% MLM) and 5.98 g/R/d (100.00% MLM). The average daily feed intake (60.08 g/R/d) obtained in animals fed the control diet reduced (P < 0.05) to 53.44 g/R/d (25.00% MLM), 53.44 g/R/d (50.00% MLM), 55.36 g/R/d (75.00% MLM) and 51.52g/R/d (100.00% MLM) respectively. Cost of feed per kg live weight gain were ? 471.39 (0.00% MLM), ? 396.80 (25.00% MLM), ? 459.52 (50.00% MLM), ? 454.67 (75.00% MLM), and ? 473.24 (100.00% MLM). The percentage dressed weight, head, feet, shoulder, loin, thigh and fore legs were significantly (P < 0.05) affected by the dietary treatments. The highest dressed weight (55.12%) was obtained in rabbits fed 0.00% MLM-based diet compared with 45.51, 46.32, 50.28 and 44.88% respectively in animals fed 25.00, 50.00, 75.00 and 100.00% MLM. All the organs (heart, lung, kidney and stomach) except the liver were significantly (P < 0.05) affected by the dietary treatments. All haematological (haemoglobin, packed cell volume, white blood cell and red blood cell); and serum (glucose and total protein) metabolites except albumin investigated were significantly (P < 0.05) influenced by the dietary treatments. It was concluded that MLM can economically replace 75% SBM (5%) in growing rabbits' diets; but 25% (1.25%) level of substitution was the cheapest and most economical level with no deleterious effects on carcass and health status of the animals.

Two experiments of a factorial design (sex × treatment) were conducted to determine the effects of enzyme and salinomycin supplementation on the nutritive value of barley or rye-based diets for growing pigs fed from approximately 20 to 85 kg. For exp. 1, 72 crossbred pigs were fed either a barley-based control diet or a similar diet supplemented with enzyme (Aspergillus niger; 750 units g−1 beta-glucanase and 650 units g−1 pentosanase), salinomycin (25 ppm) or both additives in combination. For exp. 2, two replicates of 48 pigs were fed either a barley-based diet, an unsupplemented rye-based diet or a rye-based diet supplemented with enzyme, salinomycin or both additives. During both experiments, chromic oxide (0.5%) was added to the diet of four to six pigs/treatment to act as a digestibility indicator starting when the pigs reached 42 kg. Neither enzyme nor salinomycin, alone or in combination, significantly improved the growth rate or feed efficiency of pigs fed barley or rye. Supplementation of barley with the combination of additives significantly (P < 0.05) improved protein digestibility while neither enzyme nor salinomycin had any effect on nutrient digestibility when fed alone. In rye-based diets, salinomycin, both alone and in combination, significantly (P < 0.05) improved the digestibility of crude protein and energy. Dry matter digestibility of the rye-based diets was unaffected by treatment. Key words: Swine, rye, barley, beta-glucanase, pentosanase, salinomycin

A nine (9) weeks feeding trial was conducted on seventy two (72) day-old Indigenous turkey poults raised on deep litter to determine their growth performance, carcass and economic characteristics when fed three dietary treatments (T1, T2, and T3, containing 0%, 25% and 50% replacement of maize with millet respectively. The birds were divided into three replicates of 8 birds per replicate; making a total of 24 birds per treatment. At the end of the & week, 4 birds per replicate were transferred to specially-designed metabolism cages for a digestibility study involving the collection of faecal droppings; while at the end of the week of the experiments, two birds per replicate were randomly selected and slaughtered to determine their carcass characteristics. Turkey poults fed millet at 25 %replacement showed significantly (p<0.05) higher body weight gain, lower cost of feed per kg live weight gain and higher revenue generated per bird; but there were no significant (p>0.05) differences in the performance of birds on 0% and 50 % replacements for those parameters. Also, there were no significant (p>0.05) differences in feed intake and mortality across the treatments. Similarly, there were no significant (p>0.05) differences in nutrient digestibilities and carcass characteristics of the birds among the various dietary treatments. Therefore, it can be concluded hat millet cam be used to replace maize up to S0 % in the diets of turkey poults at the starter phase with no detrimental effects on their performance

A 4 week experiment involving 45 growing albino rats was carried out to assess the nutritional utilization of cooked full-fat soybean (CFFS) as a major source of dietary protein relative to that of the protein concentrates fishmeal-groundnut cake mixture and the response to supplementation of the cooked soybeans with 2g DL-methionine/kg diet and/or 2g L-lysine/kg diet. Feed intake (FI), average daily weight gain (DLG),. feed conversion ratio (FCR), protein efficiency ratio (PER) and feed cost (FC) per unit live-weight gain, (FC/WG) were measured, No significant effect of the various dietary treatments was observed on PER and FCIWG. However, the incorporation of CFFS either alone or in conjunction with either of both lysine and methionine significantly improved Fl and FCR (P< 0.05) and also DLG (P< 0.01) over the control fish-groundnut meal ration. Supplementation of CFFS with lysine either alone or along with methionine appeared unwarranted as methionine supplementation alone resulted in similar or slightly better efficiency of protein (0.247) and overall feed (0.596) utilization. From the results obtained, it appears that maize-based CFFS diet supplemented with 2 g/kg DL-methionine may be applicable for lion- ruminant feeding. However, since this level of methionine supplementation only provides for 67% of rat requirement, it is suggested that further studies with higher methionine levels be conducted.

Abstract Supplementation of ruminant diets with the investigational methane (CH4) inhibitor 3-nitrooxypropanol (3-NOP; DSM Nutritional Products, Switzerland) is as a promising mitigation strategy. However, most studies have examined high grain or mixed forage-concentrate diets. The objective of this study was to evaluate the effects of supplementing a forage diet with 3-NOP on rumen fermentation, CH4 emissions and apparent total-tract nutrient digestibility. Eight ruminally cannulated beef heifers (BW = 514 kg) were randomly allocated to two treatments in a crossover design with 49-d periods. Dietary treatments were: control, high-forage diet (90% forage DM basis) without 3-NOP; and NOP, control diet supplemented with 150 mg 3-NOP/kg DM. After a 14-d diet adaption, dry matter (DM) intake (DMI) was recorded daily. Rumen contents were collected on days 17 and 28 for volatile fatty acid (VFA) analysis, whereas ruminal pH was continuously monitored from day 20 to 27. Diet digestibility was measured on day 38 to 41 by total collection of feces. Enteric CH4 emissions were measured on days 46 to 49 in chambers. Dry matter intake was lower (P = 0.001) for NOP (10.0 kg/d) as compared with control (10.2 kg/d). However, DM, neutral and acid detergent fiber, and crude protein digestibilities were similar between treatments (P ≥ 0.29). Although total VFA concentration was not affected by treatment (P = 0.19), the reduction in acetate and increase in propionate proportion for NOP lowered (P &lt; 0.001) the acetate to propionate ratio by 18% as compared with control. Mean pH was lower (P = 0.03) for control (6.46) than NOP (6.57). Furthermore, CH4 yield (g/kg DMI) was 21.6% less (P &lt; 0.001) for NOP relative to control (25.5 g/kg DMI). Overall, the results indicate that enteric CH4 emissions were effectively decreased with 3-NOP supplementation of a forage diet without affecting apparent total-tract digestibility of nutrients.

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.
