抄録

Five different sources of fibre, cellulose powder, carboxy methyl cellulose, rice hull, alfalfa meal and soybean oil meal were fed to day-old White Leghorn male chicks for 4 or 8 weeks at 4 different dietary fibre levels. Test diets were so prepared that all of them contained the same levels of crude protein and total digestible nutrients, and adequate levels of minerals and vitamins. Basal diets for starting and growing chicks contained 1.24% and 2.06% of crude fibre, respectively.<br>In Expt. 302, triplicated lots of 15 chicks each were fed 5 starting diets for 4 weeks in two electrically heated battery brooders. Then, the chicks of 3 groups out of 5 were moved to cages and experiment was continued until 8 weeks of age, 6 lots of 6 birds each being used as a group. In Expt. 305, 4 groups of duplicated lots of 18 chicks each were fed 4 different diets for 4 weeks. Three groups were moved to cages and experiment run as in Expt. 302. In Expt. 311, triplicated lots of 15 chicks each were fed 3 different diets for 4 weeks.<br>No significant difference in growth rate and feed efficiency was observed among the chicks fed the diets of different fibre levels of different sources. It is concluded that the dietary fibre level has little influence on performance of starting and growing chicks, when the dietary levels of energy, protein, minerals and vitamins were controlled carefully.
