Effect of Dietary Modified-Banana-Tuber Meal Substituting Dietary Corn on Growth Performance, Carcass Trait and Dietary-Nutrients Digestibility of Coloured-Feather Hybrid Duck

<p class="abstrak2">In this experiment, we investigate the effect of modified banana tuber meal (M-BTM) to substitute dietary maize in growing-finisher colored-feathered hybrid duck. One hundred and ninety six hybrid ducks (Pekin x Khaki Campbell) with 421.31 ± 0.183g body weight (BW) were allotted to 5 dietary treatments with 9 ducks (unsexed) per pen and 4 replications per treatment. These dietary treatments were: NC (negative control; maize-soyabean-meal based diet), BTM25 (25% maize was replaced by M-BTM-), BTM50 (50% maize was replaced by M-BTM), BTM75 (75% maize was replaced by M-BTM), and BTM100 (100% maize was replaced by M-BTM). The experimental design applied using completely randomize design (CRD). Data of this experiment were statistically analysed by one-way-analysis-of-variance of SAS University version 4.0 red hat (64-bit) University Online Edition. Result demonstrated that M-BTM improved significantly (p&lt; 0.05) digestibility of dry matter and crude protein. It is concluded that M-BTM enhanced apparently growth performaces and digestibility parameters of colored-feathered hybrid duck (Pekin x Khaki Campbell).</p>

Decreased nutrient digestibility due to viscosity is independent of the amount of dietary fibre fed to growing pigs

Fibre content and its effect on chyme viscosity are associated with changes in the digestive system of humans and pigs. It is unclear if fibre content and viscosity affect digestive function independently or interactively. We evaluated apparent ileal digestibility (AID) of nutrients and intestinal function in thirty-six ileal-cannulated barrows fed for 29 d either maize–soyabean meal (MSBM) or high-fibre MSBM + 30 % distillers dried grains with solubles (MSBM + DDGS) modified to three levels of viscosity by adding 5 % non-viscous cellulose (CEL), 6·5 % medium-viscous carboxymethylcellulose (MCMC) or 6·5 % high-viscous CMC (HCMC). Digesta were collected on days 27 and 28 and intestinal samples on day 29. Feeding CMC, regardless of fibre content, increased viscosity of whole digesta (P = 0·003) and digesta supernatant (P < 0·0001) compared with CEL. Feeding MSBM + DDGS or CMC decreased AID of DM (P = 0·003; P < 0·0001) and crude protein (P = 0·02; P < 0·0001) compared with MSBM or CEL. Feeding CMC regardless of fibre content increased jejunal crypt depth (P = 0·02) and ileal goblet cell area (P = 0·004) compared with CEL. Adding DDGS or CMC did not affect villus height and gene expression of jejunal monosaccharide and amino acid transporters. Feeding HCMC, regardless of fibre content, elevated amylase activity by 46 and 50 % in jejunal (P = 0·03) and ileal digesta (P = 0·01) compared with CEL. In summary, diets with increased viscosity decreased nutrient digestibility and induced intestinal changes that were independent of the amount of fibre fed.

THE EFFECTS OF GRADED LEVELS OF BREWEARS’ SPENT GRAINS AND KOLAUNT POD MEAL ON THE PERFORMANCE CHARACTERISTIC AND CARCASS QUALITY RABBITS

Thirty six New Zealand fryer rabbit (bucks) averaging 874g in body weight were fed on three diets blended with 0, 7, 14% kolaunt pod meal (KPM) and10, 20, and 30% Brewers spent grains (BSG). Other dietary components included maize, soyabean meal, bone meal, salt and vitamin-mineral mixture. The trail lasted for 98 day. Significantly differences (P < 0.05) were found among the three rations with respect to daily live weight gains, feed intake and water intake. There were significant difference among the rations with respect to percent carcass yield, feet, blood and unemptied alimentary canal. However there were no significant (P > 0.05) differences among the three rations with respect to head, tail, and liver weight expressed as percentage of live weight. There was no significant treatment effect no the wholesale cuts. The chemical composition of the meat of rabbits fed 14% KPM + 3-% BSG diet was significantly lower in energy value, % moisture and % fat. The results showed that a diet fortified with 30% BSG and 14% KPM will support good growth as well as improved carcass yield of rabbits.

Growth performance and feed cost benefit of broiler chickens fed Acha grain-based diet supplemented with different plant protein sources

Conventional energy sources for poultry feed are scarce, expensive and highly competed for by man and industry in Nigeria which has resulted to subsequent high cost of feed and at times, poor quality of feed sold to farmers. Therefore, this study was carried out to evaluate the growth performance and feed cost benefit of broiler chickens fed various plant protein sources in acha grain based diet. A total of 120, one day-old Abor acre broiler chicks were procured and assigned in a Completely Randomized Design to four dietary treatments of three replicates and ten chicks per replicate. The four diets comprise soybean meal (full fat), soybean cake, groundnut cake and cashew nut meal at 28% inclusion level each in an acha based diet. Data on growth parameters (Daily feed intake, Final Weight Gain, Total Weight Gain, Feed-to-gain ratio and mortality) were collected daily and weekly. The results showed that the birds fed diet 3 having soyabean meal as the main plant protein source with 2700 Kcal/kg ME gave the best growth performance. It is also important to note that, the growth performance of birds fed diet 4 which had 28% cashew nut (full fat) had the poorest feed-togain ratio. The findings from this study further showed that using cashew nut (T4) as plant protein source in poultry (broiler chicken) ration is rather too expensive and production of cashew nut may have to increase so as to bring down the cost of production of broiler chicken. There was significant difference (P<0.05) in all the variables of feed cost benefit analysis. It is concluded that soyabean, whether used as meal/cake or full-fat confirmed its superiority over groundnut cake and cashew nut meal in this study. It is therefore recommended that farmers or poultry feed producers should use acha based diet with either soyabean meal or full-fat soyabean Les sources d'énergie conventionnelles pour l'alimentation de la volaille sont rares, coûteuses et très concurrencées par l'homme et l'industrie au Nigéria, ce qui a résulté en un coût élevé des aliments et parfois, une mauvaise qualité des aliments vendus aux agriculteurs. Par conséquent, cette étude a été réalisée pour évaluer les performances de croissance et les avantages en termes de coûts d'alimentation des poulets de chair nourris avec diverses sources de protéines végétales dans un régime à base de céréales acha. Un total de 120 poussins de chair Abor acre d'un jour ont été achetés et assignés dans une conception complètement aléatoire à quatre traitements diététiques de trois répétitions et dix poussins par répétition. Les quatre régimes comprennent la farine de soja (pleine matière grasse), le tourteau de soja, le tourteau d'arachide et la farine de noix de cajou à un taux d'inclusion de 28% chacun dans un régime alimentaire classique. Les données sur les paramètres de croissance (ingestion journalière, gain de poids final, gain de poids total, rapport alimentation / gain et mortalité) ont été collectées quotidiennement et hebdomadairement. Les résultats ont montré que les oiseaux nourris avec le régime 3 contenant de la farine de soja comme principale source de protéines végétales avec 2700 Kcal / kg ME ont donné les meilleures performances de croissance. Il est également important de noter que les performances de croissance des oiseaux nourris avec un régime alimentaire 4 contenant 28% de noix de cajou (gras) présentaient le rapport alimentation / gain le plus faible. Les résultats de cette étude ont en outre montré que l'utilisation de la noix de cajou (T4) comme source de protéines végétales dans la ration de volaille (poulet à griller) est plutôt trop coûteuse et que la production de noix de cajou peut devoir augmenter afin de réduire le coût de production du poulet à griller. . Il y avait une différence significative (P <0,05) dans toutes les variables de l'analyse coûts-avantages des aliments. Il est conclu que le soja, qu'il soit utilisé comme farine / tourteau ou gras entier, a confirmé sa supériorité sur le tourteau d'arachide et la farine de noix de cajou dans cette étude. Il est donc recommandé que les agriculteurs ou les producteurs d'aliments pour volaille utilisent un régime à base d'acha avec du tourteau de soja ou du soja entier.

Performance And Serum Metabolites Of Grower Pigs Fed Groundnut Cake, Extruded Soyabean Meal And Cottonseed Cake-Based Diets

The study assessed the effect on performance and serum metabolites of ninety grower pigs fed extruded full-fat soyabean meal (ESBM) and cottonseed cake (CSC) as partial (-50%) and whole (100%) replacement for groundnut cake (GNC) in practical-type diets over 12 weeks feeding period. Ninety Large White X Landrace pigs average initial live weight of 30.50+1.4kg were randomly assigned to five dietary treatments and each treatment had three replicates The diets were iso-nitrogenous and iso-caloric. The ESBM in the diets showed an improvement in average daily weight gain and eed conversion. Diet in which there was 50%replacement of GNC with ESBM gave the best result (P<0.05). However, general trend showed a numerical increase with levels of ESBM and CSC in the diets. Serum albumin and cholesterol levels were significantly (P<0.05) reduced by inclusion of extruded full-fat soyabean meal, and CSC while serum creatinine level was increased.

BIOECONOMICS OF FEEDING RAW OR HEAT TREATED SOYABEANS TO BROILERS4

The bioeconomics of feeding full-fat raw (RSB), toasted (TSB), cooked (CSB) soyabeans or defatted soyabean meal (SMB) to broiler chicks at starter and finisher phases was investigated using 240 Anak strain broiler chicks. At starter phase RSB diet significantly (P < 0.05) depressed average daily intake (ADI) only when compared with SMB diet. It also significantly (P <0.01) depressed daily weight gain (DWG): with values of RSB (20.1 gin), TSB (241 gm), CSB (24.0gm) and SMB (253 gm) as well as feed conversion ratio of RSB (3.03) TSB (2.63), CSB (2.49) and SMB (2.58). At finisher phase, the effects were not significant (P> .0.05) suggesting adaptation of the chick to RSB with time. SMB diet was almost twice as costly to produce as the other three diets. Cost of feed per unit of weight gained was highest (P < 0.05) with SMB diet followed by RSB diet while CSB and TSB diets were similar at starter phase. At finisher phase SMB diet still had significantly (P < 0.01) higher cost per kg weight gain than the RSB, TSB and CSB diets whose values were statistically the same. On gross margin, the use of SMB diet significantly (P < 0.01) resulted in the lowest values, followed by the RS B diet while the values of CSB and TSB diets remained similar and the highest at both phases. This underlines the importance of using cost of food consumed to obtain a unit of product as a basis for recommending feeds to farmers (alongside other nutritional factors).

EFFECT OF PERIOD OF BOILING FULL-FAT SOYA BEANS ON ITS AMINO ACID PROFILE AND ON PERFORMANCE OF PIGS

Amino acid analysis and 2 growth studies were carried out to determine the effect of period of boiling of full-fat soyabeans on their nutritive value for weanling and growing pigs. Soyabeans were boiled in water for 15, 20, 25 or 30 minutes in Experiment 1 and 25, 30, 35 or 40 minutes in Experiment 2. Forty cross-bred (Large White x Hampshire) pigs were used in each of the experiments. Period of boiling had no effect on amino acid analysis of full-fat soyabeans. Weanling pigs had the best growth performance when soyabeans were boiled for 30 minutes ad this was not significantly different (P>0.05) from the soyabean meal control diet. Period of boiling of full-fat soyabeans did not significantly (P>0.05) affect the performance of the heavier pigs, although improvfement was observed up to 30 minutes of boiling.

Utilization of diets containing cashew-nut reject meal by weaner pigs

A trial was conducted to assess the performance and digestibility of weaner pigs fed diets containing cashew nut reject meal (CVM). A control dier was formulated without cashew nut reject meal while two other diets were also formulated to contain either 50g or 100g/kg diet. The CNM replaced soybean meal in the control diet and the three diets were isocaloric and isoproteinous. Twelve six weeks old weaner pips (7.5 ± 0.89kg) were assigned on weight equalization basis to the three dietary treatments. Records of perforinance and some haematological parameters were taken. The digestibility of dry matter and the proximate fractions of feed were also determined Feed intake of pigs un the CNM diets were lower (P<0.05) than those in the control group but there were no significant effect (P >0.05) of CRM inclusion on weight gain and feed.gain ratio. Protein efficiency ratio and apparent protein digestibility were highest in the soybean meal control diets. Pigs fed CM diets had higher creatinine levels in their serwn compared with the control diet. There were no significant differences among the dietarv treatments for total protein, albumin, globulin, urea and cholesterol. It was concluded that CNM can be included in the diets of weaner pigs to replace soyabean meal up to 10% level with little or no deleterious effect on rate of gain.

EFFECT OF VARYING LEVEL OF FISHMEAL SUBSTITUTION WITH SOYABEAN MEAL ON CERTAIN SERUM METABOLITES AND HAEMATOLOGICAL INDICES IN CHICKENS

The effect of substituting fishmeal protein with soyabean meal protein on serum metabolism and some haematological indices, have been assessed, using Hyperco broiler chickens. Six diets (isonitrogenous and isocaloric) were fed, in which, 0, 20, 40, 60, 80 and 100% of dietary fishmeal (FM) protein was substituted with soyabean meal (SMB) protein. Results showed significant (P < 0.05) differences in clotting time, packed cell volume (PCV), red blood count (RBC) and mean corpuscular volume due to dietary treatments. Clotting time was longest for birds on diet 6 in which FM was completely with SMB and shortest for those on diet 3. The variations in the PCV, RBC and MCV followed no particular trend with dietary treatments. The hemoglobin concentration (Hb), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) did not differ significantly (P > 0.05). Total serum protein (TSP), albumin, globulin and albumin/globulin ratio, were not significantly (P > 0.05) influenced by the dietary treatments. However, significant (P < 0.05) differences were obtained in the serum urea levels as the values seemed to increase with increasing Revel of FM substitution with SBM. It was inferred, that an all-SBM feeding may have serious implications for the routine debeaking processes, especially in layers, given the much higher clotting time for birds on diet 6 m which there was 100% substitution of FM with SBM protein
