Nutritive value of vegetable protein diets for broiler chickens and selection of diets containing different vegetable or animal proteins

Two experiments were carried out to ascertain the nutritional value of potato waste meal (PW) as a replacement for corn in practical poultry diets using 320 male and 320 female Cobb chicks fed from 1-day-old to 46 days (exp. 1) and 49 days (exp. 2) a basal cereal-based diet containing soybean and fishmeals or test diets each containing 50 g, 100 g, 150 g, 200 g and 300 g PW/kg. In both experiments, the diets were analyzed for elemental and amino acid composition, and the growth responses on the test diets were evaluated individually over a period of 28 days and 46 days or 49 days of ad libitum feeding. Although PW appeared limiting with respect to methionine and cystine, arginine and the aromatic amino acids, it was found that upon supplementation with methionine (0.5 g/kg), the test mixtures exhibited a synergistic effect compared with controls, and that this potato byproduct can be considered a good substitute ingredient for a proportion (200 g/kg) of the ground corn in a practical diet for broiler chickens. Feeding PW at a rate of up to 200 g/kg resulted in optimum biological response and monetary returns. The inclusion of up to 300 g/kg PW in the diets did not increase wetness of the litter or hardness of pellets, two factors reported earlier which could limit the use of PW in animal diets.

Three experiments were conducted with broiler chickens to study the effects of replacing commercial Herring fishmeal with fishmeals prepared form crayfish, sardine, mudskeeper and mullet. In the first experiment, there were no significant differences in the performance, carcass dressing percentages and the composition of the hearts and livers when any of the locally prepared fishmeals replaced the commercial fishmeal in rations. Rations without fish meal depressed performance and carcass/neck dressing percentages significantly but did not affect the composition of the hearts and livers. In experiment 2, the fishmeals were fed at a supplementary level of 7.5% and at a level (20%) in which they constituted the only source of supplementary protein. In this experiment, performance of birds fed 7.5% of the different fishmeals were similar to those observed in the first experiment. When the fishmeals constituted the sole source of supplementary protein, performances of the birds were similar for all fishmeals and were better than when 7.5% fishmeals was fed in the ration in addition to groundnut meal. The ration containing groundnut meal as the sole supplementary protein source depressed performance of birds. In Experiment 3 the total protein efficiency ration (TPE) of the different fishmeal rations were assessed. The TPE for all the fishmeal ration were not significantly different and were significantly better than that of rations without fishmeal
