Methionine supplementation in the productive efficiency, carcass characteristics and economics of growing indigenous turkey

The effect of dietary methionine supplementation at varying levels on the productive efficiency, carcass characteristics and economics of growing indigenous turkey was investigated. Four Isocaloric and Isonitrogenous diets were formulated. The diets were supplemented with 0.00%, 0.05%, 0.10%, and 0.15% respectively. Eighty (80) turkey poults and aged 12 weeks, were randomly allotted to the four dietary treatments at 20 birds each, and subdivided into 2 replicates having 10 poults each in a completely Randomized design experiment. The trial lasted 8weeks. The feed:gain ratio showed no significant (p>0,05) difference, though diet 2 proved to be the best. Birds fed diet 2 also had a higher body weight than the others. The values of parameters such as dressed weight (g), carcass yield (%BW), meat (PDW) Bone (PDW), abdominal fat and meat-to-bone ratio did not differ significantly (P>0.05). However, birds fed diet 2 gave the highest meat (PDW) and meat-to-bone ratio. The overall relative cost per kg gain that is most beneficial was obtained by feeding diet 2. The results indicate that supplementing growing turkey feed- containing 18%CP and 2800 Keal/kg ME with 0.05% methionine enhances productive performances, good carcass yield and production cost.

The effect of forage to concentrate ratios on the performance of weaner rabbits

The effect of forage to concentrate ratios on the performance of weaner rabbits was investigated using twenty (20) weaner rabbits. They were randomly assigned to five treatment diets/with two replicates of two (2) rabbits per pen in a completely randomized design CRD). The experiment lasted for 56 days. T1 = forage 80%: concentrate 20%, T2 = forage 60%: concentrate 40%, T3 = forage 40%: concentrate 60%, T4 = forage 20%: concentrate 80% and T5 = forage 50%: concentrate 50% served as the control. Data were collected for feed intake, weight gain, carcass quality and the economics of the diet. The growth performance result was significantly different (p<0.05) for all the parameters considered except for total feed intake. Treatment 3 (T3) had the highest value for final weight (1423.0 g), total weight gain (925.5g) and daily weight gain (16.52 g), with the least feed conversion ratio of (2.58) among others. The cut parts results showed that there was significant difference (p<0.05) for all the parameters considered. T3 also had the highest value for the prime parts. The organ weights results did not follow any specific pattern that could be attributed to the effect of the test ingredients. The economics /gross margin showed that T3 was favoured among others (N 731.38, N929.18, N1045.78, N828.81, N825.39),T3 (forage40%:concentrate60%) was therefore recommended.Keywords: Effect, Forage :Concentrate ratios ,performance, weaner rabbit

Performance and internal organ quality of broiler chickens fed blood meal as a substitute for synthetic lysine

A study was conducted to establish the suitability of blood meal (BM) as substitute for synthetic lysine (SL) in broiler diets. There were five dietary groups, each containing 30 unsexed day old chicks of Anak strain, replicated three times with ten birds per replicate in completely randomized design (CRD). Diet 1, which served as control contained 1.0 gKg-1 SL and no BM. Diets 2, 3, 4 and 5 without SL contained 10, 20, 30 and 40 gKg-1 BM calculated to supply 0.7, 1.4, 2.1 and 2.8 gKg-1 dietary lysine in the same order. All diets were isonitrogenous (230 and 200 gKg-1) for the starter and finisher phases and isocaloric (11.90 and 12.30 MJME/kg) for both phases respectively. The study lasted 28 days for both phases and effects of the diets on growth, carcass yield and internal organ quality of the birds were studied. At the starter phase, differences in body weight and feed: gain ratio were not significant (p>0.05), while feed intake was lowered (

Bioefficacy And Economics Of Ronozyme™ P As A Substitute For Bone Meal In Turkey Poult Ration

The biological and economic efficiencies of Ronozyme ™ p as a substitute for bone meal in female Turkey poults was investigated. A total of eighty local female poults were brooded and fed commercial broiler starter diet containing 23% CP and 2800kcal/kg ME from day-old to four weeks of age. Sixty (60) female poults were thereafter randomly selected and allotted to each of the four experimental groups of fifteen (15) birds each. Each diet was fed to triplicate groups of five poults for 8 weeks in a completely randomized design. A total of four isocaloric and isonitrogenous diets containing 25 CP and 2932kcal/kg ME were formulated. Each of the diets was supplemented with Ronozyme TM P while inclusion level of bone meal was varied from diet 1 to 4 respectively. Of all the production and economic parameters considered only the mean daily feed intake was significantly (P < 0.05) influenced. Diet 2 proved to be the best, by having the best feed to gain ratio (2.55), and higher gross margin (₦1,356.35). The difference in the mean total body weight gain for the two diets (2, 323.33 (D2) and 2,380.00g (D3)). It was concluded that 2% level of bone meal inclusion in poults diets proved better than diets having 3%, 1% and 0% respectively, especially when supplemented with 30g of Ronozyme TM P as recommended. This will cut-down cost and also probably improve calcium and phosphorous availability and absorption.Keywords: Bioefficacy, RonozymeTM P, bone meal, turkey poult ratio

Effect Of Replacing Soybean Meal With Lima Bean Meal On Finishing Broiler Chicken

Lima beans (Phaseolus lunatus) was processed by soaking and toasting before usage to feed 75 broiler birds for 28 days. The birds were randomly assigned to five treatment diets with each treatment being replicated three times and containing five birds per replicate in a completely randomized design. The bean was soaked for twenty four (24) hours, oven-dried and then toasted. It was milled and then incorporated into diets. Excepts diet 1, each of the diets (2-5) contained quantitative replacement of soyabean with the processed lima bean at 5%, 10%, 15% and 20% levels respectively. The result showed a significant (
