  The objective of the study was to evaluate the effect of feeding time restriction during starter period on compensatory growth and thyroid hormone concentration of broiler chickens. Four hundred of 7 days-old unsexed broiler chicken of Ross commercial strain were used a completely randomized design with 4 treatments. The treatments were: broilers were fed ad libitum as control group (P-0); broilers had to feed during 15 h/d (07:00 to 10:00; 12:00 to 15:00; 17:00 to 20:00; 22:00 to 01;00; 03:00 to 06:00) from 7-21 d of age (P-1); broilers had free access to feed during 12 h/d (07:00 to 10:00; 13:00 to 16:00; 19:00 to 22:00; 01:00 to 04:00) from 7-21 d of age (P-2); broilers had free access to feed during 9 h/d (07:00 to 10:00; 15:00 to 18:00; 23:00 to 02:00) from 7-21 d of age (P-3). The treatments consisted of 5 replicates with 20 chicks per pen. Feed intake and body weight gain of feeding time restriction broiler (P-3, P-2 and P-1) was significantly lower than broiler fed ad libitum (P-0) during 7 to 21 d of age. During this period, feed conversion ratio of P-3 had better than P-0, P-1 and P-2. There were no significant difference among all treatments on feed intake, body weight gain and feed conversion ratio during realimentation period. There were significantly lower T3 and T4 of all feeding time restriction broiler than broiler fed ad libitum. However, T3 and T4 were normalized during realimentation period. It was concluded that feeding time restriction during starter period had compensatory growth phenomenon and similar body weight with control and thyroid hormones profile were normalized during realimentation period.

  Background and Objective: The availability of rice hulls has become infrequent due to competition and the development of residual rice byproducts; therefore, it has forced farmers to seek alternative litter materials. The objective of this study was to investigate the effect of using betel nut husks compared to rice hulls or dried leaves as litter material for broiler production on productive performance, carcass traits and internal organ characteristics. Materials and Methods: A total of 270 unsexed one-day-old broiler chicks (Lohmann) were included the study; a completely randomized design including three treatments with six replicates consisting of 15 chicks each was applied. The treatments comprised betel nut husks, rice hulls and dried leaves as litter materials. Standard feeding and management practices were followed during the experimental period. The body weight and feed intake were recorded weekly and the body weight gain and feed conversion ratio were calculated. Two broilers from each pen were used to measure the carcass traits, abdominal fat pad quantity and internal organ weight at 35 day of age. Results: The results from the present study showed that the litter materials did not affect (p>0.05) body weight gain, feed intake and feed conversion ratios during the experimental period. The carcass yield and abdominal fat quantity were not influenced (p>0.05) by the litter material. There was no difference (p>0.05) among the three litter materials in the internal organ weight; however, the gizzard weight was higher (p<0.05) in the broilers reared on rice hulls than in those reared on dried leaves and betel nut husks. Conclusion: Betel nut husks can be used as an alternative litter material for broiler production without sacrificing the performance of broiler chickens.
