Abstract :

One hundred and fifty,day-old commercial oiler chicks (Vencobb-400) were allotted to 3 dietary treatments with 5 replicates each and 10 birds per replicate in a completely randomized design. An iso-caloric and iso nitrogenous maize-soya based oiler feed (BIS 2007) ground in hammer mill using 3mm, 5mm and 7mm screens was offered from day 1 to 42.Homogenously mixed 6 samples of each experimental ration were taken for the measurement of particle size distributions using laboratory sieves of 4.76, 2.00, 1.00 and 0.50 mm screens. Result reveals that hammer mill screen opening of 3mm, 5mm and 7mm did not differ significantly inweight and length of different segments of digestive tract, processing yields and losses and abdominal fat per cent of oiler at 42 days of age.
