Determinations of protein content and proximate analysis of castor cake for protein supplementation in poultry feed

الملخص

The world population is rapidly increasing. rapidly increasing world population is  demanding more food. Addressing this demand requires growth in agricultural outputs including eatable animals (livestock, poultry, and fish) and, their products. However, these animals by themselves need food, which is usually competing with human food. Besides, some animals and human foods are industrially competitive, Which makes feeds less available and costly. As a result, the cost of animals and animal products is drastically increasing. Thus, to address these tradeoffs either optimize the consumption of the feeds or looking for alternative feeds is required  for  poultry feeding. This study focuses on determinations of protein content and proximate analysis of castor cake for protein supplementation in poultry feed.Cake left after  solvent extraction was detoxified with a chemical method (lime treatment 10gm/kg cake) followed by a physical method (autoclaving at 15 psi for 30 min)  and the ricin level was quantified with UV spectroscopy.The result showed that insignificant ricin  was found in the castor. The Proximate analysis of the cake was a Moisture content of 9.1% carbohydrate 5.5% fat content 24.3% Ash content8.3%  Fiber content20.3%.
