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.

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.

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 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.

The effect of diets containing 0% of wheat bran levels (control buffel grass and cactus pear) contrasted with diets with cactus pear as the only forage source and wheat bran levels (30; 37 and 44%) on nutrient digestibility, feed intake, animal performance, carcass characteristics, and economic analysis was evaluated. Twenty-eight male, non-castrated crossbred lambs (22.6 ± 2.37 kg) were submitted to confinement for 62 days. A completely randomized design was used with four treatments and seven repetitions. Four diets were formulated considering an intended mean daily weight gain of 200 g/animal/day. Means were compared by contrasts using Dunnett test at 5%. Animals fed cactus pear as the only roughage source (diets with 30; 37, and 44% of wheat bran) had lower dry matter intake and nutrient intake, Average Dairy Gain, and total weight gain than animals fed the control diet. Final body weight and slaughter weight of animals fed 44% of wheat bran was similar to the animals fed the control diet. Hot and cold carcass yields were higher in animals fed cactus pear and 30 and 37% of wheat bran. Feeding costs were lower when cactus pear was used as the only roughage source associated with wheat bran and consequently profit was greater. The use of cactus pear as the only roughage source associated with up to 44% of wheat bran is a viable alternative of the diet to confined lambs without modifying carcass characteristics with greater cost:benefit ratio.

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.

The aim of this study was to determine the effect of the inclusion of different lipid sources [whole cottonseed (CS) and protected fat in diets containing sugarcane, corn, citrus pulp, CS meal, and urea] on animal performance, hot carcass dressing (HCD), ribeye area (RA), fat thickness (FT), and postmortem pH of the meat of Nellore cattle during finishing. The treatments evaluated were feed with 2.50% CS (control diet, T1 treatment); feed with 11.50% CS (high CS, T2 treatment); and feed with 3.13% CS added of protected lipid (PL) (T3 treatment), all on a DM basis. The forage:concentrate ratio of the diet was 50:50. Thirty-nine intact steers with average initial body weight of 494 kg and 36 months old were confined for 63 d. The addition of lipid sources tested in this study did not affect dry matter intake, crude protein intake, neutral detergent fiber intake, final live weight, average daily weight gain, HCD, RA, FT, and meat pH. It was concluded that the addition of PLs in the diet did not affect weight gain and carcass characteristics.

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.

The progressive increase in the cost and scarcity of conventional feedstuffs, especially energy and protein sources has resulted into a continuous effort in researching into the possible utilization of the under - exploited wild legumes in poultry feed formulation. Several Researchers had reported on the utilization of Moringa oleifera leaf meal in poultry diets whereas; few reports exist on the utilization of Moringa seed. Therefore, this study wasconducted to evaluate the effect of graded dietary levels of moringa seed cake (MSC) on the performance of broiler chickens. A total of 195, one day old Arbor Acre broiler chicks were randomly assigned into five dietary treatments of moringa seed cake, each treatment having three replicates in a completely randomized design. MSC was included at levels of 0, 5,10, 15 and 20% respectively. Feed and water were given ad- libitum. Proximate composition ofMSC showed that it is high in energy, crude protein and ether extract with3304. 39 ME kcals/ kg, 32.49 % and 17.70%, respectively. Birds fed 5% MSC diet were better than the birds on the other levels of MSC diets in terms of growth and carcass characteristics. The results obtained from growth study revealed a significant declined in, final weight, weight gain, feed intake, and feed conversion ratio as the inclusion levels of MSC increased beyond 5% in thediets. The birds on control diet had the best result in terms of final weight , daily weight gain and daily feed intake of 2974g/bird, 52.4g/bird / day and 107.51g/bird/ day respectively followed by those fed diet containing 5% MSC with 2183.4g/bird, 38.24/bird /day and 95.66g/bird /day respectively. whereas, the birds fed 20% MSC had the least (P>0.05) final weight, daily weight gain and daily feed intake of 560 g/bird, 9.26g/bird /day and 33.51g/bird/day respectively. Carcass characteristics followed similar trend as the growth parameters. Hematological indices showed significant differences across the dietary treatments, however, the results were within the normal range except for the white blood cell. It can therefore be, concluded that the inclusion of MSC in broiler chicken diet should not exceed 5% for optimum growth and general performance.

In a 56-day feeding trial, an experiment was conducted to determine the effects of replacing maize with different levels of ensiled cassava root-leaf blends (ECRLB) on growth, carcass yield, blood profile and economics of production of weaner rabbits. Five experimental diets were formulated and fed to the animals; diet 1= a maize based diet (control diet), diet 2= 30% maize + 10% ECRLB, diet 3 = 20% maize + 20% ECRLB, diet 4= 10 % maize + 30% ECRLB, diet 5= 40% ECRLB. A total number of forty weaner rabbits with an initial average weight of 574.09g±20.03g were randomly allocated to the five dietary treatments in a completely randomized design (CRD) with eight animals per treatment. Data were collected on growth indices, economics of production, carcass characteristics and blood profile Increased (P<0.05) weight gain was observed as the percentage inclusion of ECRLB increased. Rabbits on diet 4 (10 % maize + 30% ECRLB) and 5 (40% ECRLB) recorded the highest (P<0.05) daily weight gain with a corresponding highest (P<0.5) final body weight. Similar FCR were recorded across the treatments Economics of production of animals on diets containing 30 and 40% ECRLB was the best (P<0.05). Carcass indices were not significantly (P>0.0) affected by the experimental diets. Rabbits fed ECRLB recorded lower (P<0.05) serum cholesterol and higher (P<0.05) serum glucose concentration compared to control. In conclusion dietary inclusion of ECRLB up to 40% improved performance and did not show any deleterious effects on all indices examined and is recommended.     Au cours d'un essai d'alimentation de 56 jours, une expérience a été menée pour déterminer les effets du remplacement du maïs par différents niveaux de mélanges racines-feuilles de manioc ensilées (le 'ECRLB) sur la croissance, le rendement de carcasses, le profil sanguin et l'économie de la production de lapins sevrés. Cinq régimes expérimentaux ont été formulés et nourris aux animaux ; régime 1= régime à base de maïs (régime de contrôle), régime 2= 30% maïs + 10% ECRLB, régime 3 = 20% maïs + 20% ECRLB, régime 4= 10% maïs + 30% ECRLB, régime 5= 40% ECRLB. Un nombre total de quarante lapins sevrés d'un poids moyen initial de 574,09 g±20,03 g ont été attribués au hasard aux cinq traitements diététiques dans une conception complètement randomisée (CRD) avec huit animaux par traitement. Des données ont été recueillies sur les indices de croissance, l'économie de la production, les caractéristiques de la carcasse et le profil sanguin. Le gain de poids accru (P<0,05) a été observé à mesure que l'inclusion en pourcentage de l'ECRLB augmentait. Les lapins de l'alimentation 4 (10 % de maïs + 30 % d'ECRLB) et 5 (40 % d'ECRLB) ont enregistré le gain de poids quotidien le plus élevé (P<0,05) avec un poids corporel final correspondant le plus élevé (P<0,5). Les 'FCR' similaires ont été enregistrés à travers les traitements Économie de la production d'animaux sur les régimes contenant 30 et 40% ECRLB a été le meilleur (P<0,05). Les Indices carcasse n'étaient pas significativement (P>0,0) affectés par les régimes expérimentaux. Les lapins nourris à l'ECRLB ont enregistré un taux de cholestérol sérique inférieur (P<0,05) et une concentration plus élevée de glucose sérique (P<0,05) par rapport au contrôle. En conclusion, l'inclusion alimentaire de l'ECRLB jusqu'à 40 % a amélioré les performances et n'a pas montré d'effets délétères sur tous les indices examinés et est recommandée.

A feeding trial lasting 63 days was conducted using 60 weaned rabbits of mixed sexes and breeds with an average initial live weight of 487.50g. The rabbits were allotted to replicates each. Cotton seed oil sludge (CSOS) was included at 0, 3, 6, 9 and 12% levels of the experimental diets respectively. The diets were isonitrogenous (20% CP). The results showed that feed intake, weight gain and feed efficiency were significantly different (P<0.05) across the dietary treatments. The highest weight gain was observed on rabbits fed diet containing 12% level of cotton seed oil sludge (CSOS). The use of cotton seed oil sludge in rabbit diet was cost effective. The percentage reduction in feed cost per kilogram of diet for the 3,6,9 and 12% level of inclusion were 2.90, 6.43, 12.04 and 15.25% respectively. The dressing percentage and percent belly fat increased significantly (P<0.05) with increase in the level of cotton seed oil sludge. A non-significant but slight increase was observed with the carcass weight and weight of the major organs (P>0.05) as the level of cotton seed oil sludge increased in the diet. It was concluded that cotton seed oil sludge (CSOS) can be included up to 12% level in the diets of young rabbits without adverse effects on performance and carcass characteristics.
