Effect of graded levels of cottonseed meal with and without ferrous sulphate on growth performance, hematobiochemical parameters in white pekin ducks [electronic resource].

Includes references.

A six weeks foeding trial was conducted to evaluate the effect of replacement of soybean meal (SBM) with cottonseed meal (CSM) with or without ferrous sulphate supplementation on the growth performance and hematobiochemical parameters of white Pekin ducks. One hundred one-day old white Pekin ducks were randomly divided into jive groups. The first group was fed standard basal diet (control group). The second group was fed diet where 20% of soybean meal was replaced with cottonseed meal (CSM20). The third group was fed diet where 20% of soybean meal was replaced with cottonseed meal and supplemented with forrous sulphate (CSM20+). The fourth group was fed diet where 41% of soybean meal was replaced with cottonseed meal (CSM41). The fifth group was fed diet where 41% of soybean meal was replaced with cottonseed meal and supplemented with ferrous sulphate (CSM41+). On the 42 days of age, blood samples were collected from the different groups (6 birds randomly selected/each group).
