Abstract
From the results summarized above it appeared that addition of the cake mixture of deoiled koranj cake and expeller pressed kosum cake at a definite proportion supplemented with lysine and methionine had depressing effect on growth performance, feed consumption, feed efficiency and dressing yield. In addition, it has definite histopathological effect on liver and kidney with the linear increase of the cake mixture in the treatment diets.
The factors responsible for the depressing effects appear to be:
(1) Due to unpalatability of the experimental diets containing increasing levels of cake mixture.
2.Due to increased level of crude fibre and oil content in the treatment diets, the higher level of crude fibre might have increased the rate of passage of digesta and may also interfere the nutrient balance during initial stage, whereas the oil content contain toxic agent(s) which might also be the cause of lower digestibility.
3.An imbalance of some of the essential amino acids and energy in the diet consequent upon the inclusion of deolled cakes and mathionine, lysine supplementation which by their comparative imbalance, are known to cause depressed growth performance in chicks.
4.It may be due to the probable presence of some unidentified anti-nutritional/toxic factor(s) in the cake mixture which were not assessed.
As such, the observations made on the growth performance, dressing characters and the histopathological findings indicated that the cakes did not form a promising combination supplemented with methionine and lysine for its favorable inclusion in poultry diet. However, further detailed studies are warranted.
