Abstract
An experiment was conducted to investigate the effect of feeding different cereals (sorghum, millet, wheat and maize) on pullets growth, subsequent performance and liver and serum total lipids. Four diets based on sorghum, millet, wheat or maize as a main source of energy. Cereals were used for growing and laying hens. Diets based on each of the four cereals were given to the birds during the growing period (12 – 18 weeks) of age and the laying hens at 19 weeks of age to the end of the experiment, which lasted for 14 weeks. Feed intake, body weight gain and feed conversion ratio of laying pullets up to 26 weeks was significantly (P<0.05) affected by the type of cereal fed. Feed intake though not significantly (P <0.05) different between birds fed sorghum, millet, or maize based diets, was minimum in the millet-based diet, minimum in wheat and intermediate in sorghum and maize. However, body weight gain was minimum in sorghum-based diet, minimum in maize and intermediate in millet and wheat. Feed conversion ratio was better (P<0.05) for birds fed wheat and sorghum compared to those fed millet and maize. Liver and abdominal fat relative weight were significantly affected (P<0.05) by the cereal used. Birds fed millet had the highest liver and abdominal fat relative weight. Serum total lipids, phospholipids, triglyceride and glucose were significantly (P<0.05) affected by the dietary treatments. Serum triglyceride and glucose were the highest in the millet based diet the lowest in sorghum and intermediate in wheat and maize based diets. Serum total lipids and phospholipids were maximum in wheat based diet, minimum in sorghum and intermediate in millet and maize diets. Liver total lipids, phospholipids and triglycerides were significantly (P<0.05) affected by the type of cereal grains fed. Birds fed wheat-based diet had the highest level of liver total lipids, phospholipids and triglycerides.
