Cottonseed Meal as Substitute for Soyabean Meal in Broiler Ration
G.S. Ojewola,S.N. Ukachukwu,E.I. Okulonye
International Journal of Poultry Science , 2006,
Abstract: In a 6 week feeding trial, cottonseed meal was substituted for soyabean meal at 0,25, 50, 75 and 100% and the diets were respectively designated as diets 1, 2, 3, 4 and 5 in a completely randomized design. Biologic and economic performance were investigated. Birds were fed and watered ad-libitum. The results showed that there were no significant differences (P>0.05) in the bird`s mean daily weight gain and feed-to-gain ratio while the mean daily feed intake was significantly (P< 0.05) influenced. Birds fed diets 3 and 4 respectively consumed 150.93g and 153.68g. This was closely followed by diets 5 and 2. Numerically, birds fed diet 3 gave the highest weight gain (2666.6g) while diet 1 was the least (2443.27g). The nutrient utilization analysis showed significant differences (P< 0.05). Diet 5 had the highest percent mean values for nitrogen (81.45), crude fibre (60.81), ether extract (95.57), ash (66.79) and dry matter (85.72) retentions while birds fed diet 1 was least for same parameters. Mineral utilization followed the same trend; diet 5 was the highest (69.08), (84.72), (71.91), (79.39) for phosphorous, potassium, calcium and magnesium respectively while diet 1 gave least values for same parameters. Diet 5 was found to be the cheapest (N290.01) and savings were significantly (P< 0.05) improved with the use of this diet while diets 1 and 3 had the least values of N285.94 and N302.67 respectively for marginal revenue. Though, the diets were comparable, diet 5 showed superior indices for nutrient utilization and economics of production. In conclusion, there is an indication that iron treated cotton seed meal can serve as a substitute for soyabean meal in broiler diet.
Effects of Partial Replacement of Soyabean Meal with Bread Fruit (Artocarpus altilis) Seed Meal in Broiler Finisher Diets on Their Performance, Water Consumption, Nitrogen Retention and Carcass Characteristics
Smart O. Nwokoro,Joseph O.I. Obasuyi
International Journal of Poultry Science , 2006,
Abstract: The study was carried out to determine the effects of partial replacement of soyabean meal in broiler finisher chickens diets with breadfruit seed meal on their performances, nitrogen retention and carcass characteristics. 300, four weeks old broiler chickens were divided into 15 replicates of twenty birds each such that three replicates were allocated to a diet. The diet (2900kcalMEkg-1 and 20%CP were formulated such that 26.7% of soyabean meal in the control diet were partially replaced with breadfruit meal at 0, 10, 20, 30 and 40 percent (weight- for- weight). The birds were fed and watered ad libitum. Results emanating from the study indicated that final body weight, weight gain, feed intake, water intake, nitrogen retention, eviscerated carcass weights and head portion were significantly (P< 0.05) affected by dietary treatments. Apart from the nitrogen retention and head portion, the control diet (diet 1) recorded the highest values and there were significant (P< 0.05) decrease between diet 1 (0) and diet 5 (40%). The best feed per gain ratio, dressing percentage and nitrogen retention were recorded in diets 1 (0), 1(0) and 3(30) respectively. There were significant increases in nitrogen retention between diet 1 and 3, followed by significant decreasing order thereafter. Higher level of breadfruit seed meal replacement beyond 30% seems not to favour the broiler finisher chickens under the conditions of the study.
Partial Substitution of Soyabean Meal with Breadfruit (Artocarpus altilis) Seed Meal in Broiler Starter Diets: Effects on Performance, Water Consumption and Carcass Characteristics
Nwokoro,Smart O.,Joseph O.I. Obasuyi
International Journal of Poultry Science , 2006,
Abstract: The study was initiated to ascertain the effect of partial substitution of soyabean meal with breadfruit (Artocarpus altilis) meal in broiler starter chickens diets reared in a tropical environment. 300 broilers chicks were used for the study and they were divided into 15 replicate groups such that three replicates were allocated to a diet. Five broiler starter diets (3000 Kcal MEKg-1 and 24% CP) were formulated such that the Soya bean meal in the diet were replaced with breadfruit seed meal at 0, 10. 20, 30 and 40% levels. The birds were fed and watered ad libitum for the 4 weeks of the study. Results indicated that final live weights of birds, weight gain, feed and water intakes, daily nitrogen retention, packed cell volume and back wholesale carcass cuts of the broilers indicated significant (P< 0.05) differences. It also showed that birds on control diet (diet 1) recorded significantly (P< 0.05) higher body weight, weight gain, feed intake than those of other diets (10, 20, 30 and, 40 % breadfruit seed meal based) which were not different from each other. There were consistent decrease in feed and water consumption with increasing breadfruit meal level of dietary inclusion. Results for the nitrogen retention revealed that the best values were recorded in diets 3 and 4 followed by diet 5, while the least were obtained in diets 1 and 2. Results for the blood metabolites indicated that only PCV and globulin showed significant differences, where only diet 5 (for PCV) were different from all other diets. Other parameters measured were not consistent. The value for the carcass back cut indicated a decreasing back cut between diet 1 and 5 with the exception of diet 3. Treatments had no effect on mortality.
Replacement Value of Cashew-nut Meal for Soyabean Meal in Finishing Broiler Chickens
G.S. Ojewola,F.C. Okoye,I. Agbakuru
International Journal of Poultry Science , 2004,
Abstract: In a 5 week feeding trial, cashewnut meal was substituted for Soyabean meal at 0, 25, 50, 75 and 100% and the diets were respectively designated as diets 1, 2, 3, 4 and 5 in a completely randomized design. Body weight changes, feed intake, feed-to-gain ratio and the economics of production were investigated. The feed-to-gain ratio was significantly (p<0.05) influenced while other parameters were not. Diet 3 gave the best value (2.24) followed closely by diets 4 (2.25) and 2 (2.28) respectively, while diet 1 had the poorest value (2.53) followed by diet 5 (2.40). The mean daily feed intake numerically improved as the percent cashewnut meal substitution increased from 0 to 100%. Birds fed diet 4 had the highest value (120.58g) while birds fed diet 1 had the least value (115.84g). The mean total body weight gain (g) was highest (2214g) for birds fed diet 3 while birds fed diet 1 had the least value (1878.00g). The cost/kg diet (N) decreased as the dietary inclusion of the test ingredient increased from 0 to 100%. At the end of the trial, the highest marginal revenue was obtained from birds fed diet 4 (N415.32). This was closely followed by birds fed diets 3, 5, 2 and 1. Cashewnut meal is therefore recommended as a substitute for the expensive conventional plant proteins at 25, 50 and 75% levels.
Evaluation of Palm Kernel Meal as Substitute for Soyabean Meal in the Diet of Growing Cockerels
G.S. Ojewola,U.K. Ozuo
International Journal of Poultry Science , 2006,
Abstract: One hundred and twenty Anak Cockerels were used in a 56-day trial to determine the substitutional value of Palm Kernel meal (PKM) for Soyabean meal in the diet of growing cockerels. The five week-old cockerels were randomly allotted to five dietary treatment groups in which the dietary soyabean meal had been substituted with PKM at 0, 25, 50, 75 and 100%. The diets were respectively designated as diets 1, 2, 3, 4 and 5. The results showed that mean daily body weight gain and feed-to-gain ratio for all the treatments were significantly (P< 0.05) influenced. Birds fed diet 2 had the highest weight gain (1229.17g) followed by birds fed diet 1 (control) while birds fed diets 3, 4 and 5 respectively had their weights depressed. Birds fed diet 2 gave the best feed-to-gain ratio (3.88). The feed cost per kilogramme diet significantly (P< 0.05) decreased with the increasing PKM replacement of soyabean meal. Diet 2 gave the least cost per kg weight gain (N159.90) and the highest accruable revenue (N614.58). From the results of this study, it would appear that substituting 25% of soyabean meal with PKM in growing cockerel diets would not only be economically advantageous but enhanced performance.

Kwari, I. D.,Igwebuike, J. U.,Diarra, S. S.
Journal of Environmental Issues and Agriculture in Developing Countries , 2010,
Abstract: The growth performance and carcass measurements of broiler chickens fed different levels of raw sorrel (Hibiscus sabdariffa) seed meal replacing soyabean meal as the major protein source were investigated in a 63-day feeding trial. One hundred and fifty day-old Anak-2000 broiler chicks were individually weighed and allotted to five experimental diets in which raw sorrel seed meal (RSSM) replaced soyabean meal at 0 (control), 25, 50, 75 and 100% levels in diets 1, 2, 3, 4 and 5 respectively. The diets and clean drinking water were offered ad libitum throughout the period of the experiment. Results of the study showed among others that final live weight and daily feed intake were depressed above 50% level of soyabean meal replacement with raw sorrel seed meal in the diets. Raw sorrel seed meal can therefore replace soyabean meal upto 50% without adverse effect on broiler performance.

M. Orunmuyi,G.S. Bawa,F.D. Adeyinka,O.M. Daudu
Pakistan Journal of Nutrition , 2006,
Abstract: A total of forty (40) growing rabbits with an average initial weight of 921.5g were randomly allotted to five dietary treatments containing 0, 10, 20, 30 and 40% palm kernel cake as replacement for soyabean cake respectively. All diets were formulated to be isonitrogenous (20% CP). The final live weights of the rabbits were higher in the control diet compared to those on palm kernel cake diets. With the exception of the rabbits placed on 40% level of palm kernel cake daily feed intake, daily weight gain and feed efficiency values compared favourably with those on control diet. Carcass weight and weight of primal cuts expressed as percentage of carcass weight did not show any significant difference between the treatment means. Animals on 40% palm kernel cake diets had the highest (P< 0.05) cost per kg gain compared to those on other dietary treatments. It was concluded that palm kernel cake can be used up to 30% level in a maize – soyabean meal based diet for grower rabbits without adverse effect on the performance of the animals.

E.V. Ezieshi,J.M. Olomu
Pakistan Journal of Nutrition , 2004,
Abstract: Studies were conducted to compare the effects of dietary PKC and maize offal on the performance of broilers. According to the results of the trial with broiler starter chicks, the birds on the control diet (without PKC or maize offal) gave the highest body weight gain (1236.37g/bird). The result further showed that the birds on maize offal diets performed slightly better (1092.17 and 1005.56g/bird) than those on PKC diets (984.12 and 877.61g/bird). The birds on PKC diets consumed more feed (2446.11 and 2416.69g/bird) than those on maize offal diets (2329.05 and 2106.94g/bird). Feed cost per kg live weight gain was generally higher with PKC diets than with maize offal diets. Average daily water intake was not significantly affected by diets (200 to 300 ml/bird/day). Dry matter retention was higher with maize offal diets (66.45 and 68.52%) than with PKC diets (59.92 and 55.24%). The birds on the control diet gave almost similar crude protein and fat retention with those on maize offal diets (about 74%). The results of the trial with broiler finisher chickens indicated that weight gain per bird slightly decreased when PKC or maize offal replaced maize in the diet. Feed intake increased slightly when 50% of dietary maize was replaced with PKC or maize offal. Feed to gain ratio increased significantly with the inclusion of PKC or maize offal in the diet. Water intake was not significantly affected by diets (400 to 500ml/bird/day). Dietary PKC significantly decreased dry matter retention. Crude protein retention was significantly higher in the maize offal diets (72.41 and 76.99%) as compared to PKC diets (59.91 and 64.25%). Fat retention significantly decreased with the test diets. From the foregoing, therefore, it can be concluded that both ingredients performed significantly well when compared to the control diet. However, maize offal seemed to have performed better than PKC in a number of parameters.
Replacement Value of Bambaranut Voandzeia subterranea Sievate for Soyabean Meal Glycin max on the Performance of Finisher Broiler Chicken
B.U. Ekenyem,C.P. Onyeagoro
International Journal of Poultry Science , 2006,
Abstract: One hundred and sixty 4-week old broiler chicks were used in a 28-day feeding trial in a completely randomized design, to evaluate the performance of finisher broiler chicks fed varying replacement values of Bambaranut sievate (BNS) Voandzeia subterranea for soyabean meal (SBM) Glycin max. The four dietary treatments were further replicated four times. Treatments having 0%, 5%, 10% and 15% BNS replaced corresponding weights of SBM in the diets. Feed and potable water were supplied ad libitum while vaccination and medication were appropriately applied. The initial weight, final weight, weight gain, feed intake, feed conversion ratio, feed cost per kg gain were measured. Results show that birds on 0% and 5% BNS with weights 1.85kg and 1.83kg respectively were significantly (P< 0.05) heavier than those on 10% and 15% BNS weighing 1.68kg and 1.65kg respectively. This trend was also observed for weight gain where birds on 0% and 5% BNS were superior (P< 0.05) to those on 10% and 15% levels respectively. However, the initial weight and feed intake were not statistically different (P>0.05), feed conversion ratio and feed cost/kg gain were significantly (P< 0.05) different between their various treatment means. BNS was found to appreciably reduce cost of broiler chick production and could be included up to 15% in chicks diets.
Influence of Strain of Chickens on Ileal Amino Acids Digestibility of Different Protein Sources
W. Al-Marzooqi,I.T. Kadim,O. Mahgoub
International Journal of Poultry Science , 2011,
Abstract: The main objective of this study was to assess the nutritional value of four protein sources (soyabean meal, fish silage, sardine fish and fishmeal) using commercial broiler and local poultry strains. Four experimental diets were formulated; representing four different proteins sources and was evaluated using six replicates of eight birds per cage at 21 day of age. Cages were located in an environmentally controlled room maintained under conditions suitable for birds at this age with a photo-period of 23 h in every 24 h. Diets and water were offered on ad libitum basis. On the fourth day after the adaptation to the experimental diets, feed troughs were removed from every cage for 1 h and then reintroduced for 2 h. Then the birds were killed to allow for sampling of ileal digesta, from Meckels diverticulum to the ileal-caecal-colonic injunction. Broiler birds showed significantly (p<0.001) higher digestibility coefficients and digestible content of amino acids across all the protein sources than the local birds. Out of the four protein sources evaluated in this study, fishmeal had the lowest amino acids digestibility coefficient for the two bird breeds (p<0.001). The digestibility coefficient and digestible content of amino acids estimates for fish silage was the highest across the two strains (p<0.001). The lower digestibility of amino acids for soyabean meal is related to the presence of; antinutritional factor, trypsin inhibitor. Fish silage shows a great potential to be used as protein supplements for poultry feeding. The results suggest that the class of chickens and protein source significantly influenced the apparent ileal digestibility and digestible contents of amino acids in the nutrient assessed in this study.
