中文摘要

The objective of the study was to determine the effect of different housing and age on growth development in large type black native chickens. Four thousand commercial black type native chickens were randomly allocated into 2 houses (wet pad and open type housing), 2000 birds in each house, the numbers of males and females were even and kept separately. During the trial, ad libitum feed and water were provided, amount of feed intake was recorded, feed residue was collected once weekly to calculate average daily feed intake per bird. For every housing and sex treatment, 100 birds were selected, attached with leg bands, weighed weekly as the source for weight gain data. Birds were kept from hatch until 13-weeks old. The results indicated that chickens kept in wet pad housing had better weight gain than those in open type housing. Weight gain decreased when chickens raised after 7 or 8-weeks old, and after 11-12 weeks decreased the most. Male chickens had better weight gain than females. Weight gain decreased gradually when male chickens raised after 8 weeks, while females raised after 7 weeks.
