IMPACT OF NEWSPAPER AS BEDDING MATERIAL IN ARID LAND ON BROILER PERFORMANCE

摘要: Two experiments were carried out to investigate the effect of using new and reused bedding materials on broiler performances. First experiment was conducted from 1 42 days age, seven hundred twenty one day-old chicks (Ross). Chicks distributed six treatments (four replicates for each). One allocated each treatment (30 birds replicates) in a completely randomized design. The were; shaving woods, barley straw, newspaper, 1:1 woods + newspaper straw respectively. Second performed bedding, which used first experiment, during finishing period (28 age). Same protocol design numbers as followed second experiment. results indicated that broilers grown had significantly highest body weight (BW), well gain (BWG). In addition, same treated consumed amount feed (FI), recorded best conversion ratios (FCR). Relative carcass glands weights not affected. However, relative full empty gizzard, intestine caeca lengths influenced by different materials. Newspaper litters retained percentages moisture. Reused insignificant final BW. Broiler significant BWG FI they FCR. Broilers relatives weight. gizzard weights, ceca length raised newspaper. (bursa fabricius, adrenal thyroid) affected moisture percentage litter. conclusion, can be rearing finisher periods arid land such Saudi Arabia. Using mixture or house improved performances litter characteristics good impact environmental condition.
