Abstract :

A study has been conducted with broilers to assess, during the rainy season, the effects of
groundnut cake substitution by glandless Cottonseed Kernel (CSK), at levels of 0, 25, 50 and 75%. The
substitution improved linearly feed intake and animal growth, as well as carcass component weights and
allometric parameters. The CSK increased the C18:2 n-6 to C18:1 n-9 ratio, as well in diet as in meat and
subcutaneous fat. In order to explain the observed performances, the possibility is considered that broilers
used preferentially C18:2 n-6 fatty acids for their metabolism. Complete glandless cottonseed kernels are
probably highly valuable for broilers production in warm and wet conditions.
