The Effect of Age and Duration of Fasting on Performance and Carcass Characteristics of Broiler Chicken

The research was conducted to evaluate the effect of age and duration of fasting on performance and carcass characteristics of broiler chicken. One hundred and eight day old chick of broiler Cobb SR 707 were randomly assigned into floor pen (0.5 m x 1.0 m x 0.8 m), in which each pen was filled with four chicks. The experiment was performed in a factorial arrangement (3 x 3) according to completely randomised design with three replication for each treatment combination. The first factor was duration of fasting, i.e. 0 h (control), 2 h (12.00-14.00 p.m.), and 4 h (11.00 a.m to 15.00 p.m). The second factor was the age of chicks when fasting was introduced, i.e. 2, 3 and 4 weeks, respectively. The result of study indicated that fasting program up to 4 h daily begin at 2 weeks of age did not alter broiler performance. Similarly, carcass characteristics, especially carcass percentage, carcass cuts and abdominal fat were not affected by fasting program. Under the research condition, fasting program did not increase the farming efficiency of broiler chicken

Body Weight Response of Broiler Chicken Subjected to Post-hatched Fasting

The research aimed to assess body weight respons of broiler chickens with various body weights (BW) at hatch when subjected to post-hatched fasting and its subsequent impact on the final body weight. Two hundred and sixteen unsexed broiler chickens, strain Cobb aged 12 hours post-hatch, were randomly assigned into floor pen (six chicks per pen). The research was arranged in a 3 x 4 factorial arrangement according to completely randomized design with three replications for each treatment combination. The first factor was the BW at hatch, i.e. light (30.1±0.39g), medium ((33.3±0.44g), and heavy (33.3±0.44g). The second factor was the duration of post-hatched fasting, i.e. 24, 36, 48, and 60 h, respectively. All chickens were weighed at 12, 24, 36, 48, 60 and 72 h post hatch, then at 7 and 35 days of age. Data analysis indicated that the BW of chicken subjected to fasting at 48 to 60 h post-hatch decreased significantly at the rate of 8.6% and 12.5% of the initial body weight, respectively. However, this condition was not related to the initial body weight status of the chicken. Availability of feed after the fasting period was not sufficient to compensate retardation of body weight of the chicken subjected to fasting 48-60 h post-hatch

Performance and Intestinal Condition of Broiler Chicken with Various Body Weight at Hatch When Subjected to Fasting Post-hatch

The research was aimed to determine the performance and intestinal condition of broiler chickens with various body weights (BW) at hatch when subjected to fasting post-hatch. Two hundred and sixteen broiler chickens Cobb aged 12 hours post-hatch and unsexed, were randomly assigned into floor pen, in which each pen filled with six chicks. The research was conducted in a factorial arrangement (3x4) according to completely randomized design with three replications for each treatment combination. The first factor was the BW at hatch i.e. light ((30.1±0.39g), medium ((33.3±0.44g), and heavy (33.3±0.44g). The second factor was the duration of fasting post-hatch (i.e. 24, 36, 48, and 60 h, respectively). Chickens respond on fasting treatment were observed on performance parameters (i.e. feed intake, growth rate, and feed conversion ratio), and intestinal dimension. Heavier chicks at hatch grew better and reached heavier final BW than smaller chicks, and were not influenced by fasting post-hatch. Fasting the chicks more than 48 h post-hatch, reduced the feed intake, retarded the growth, and had smaller intestine during the realimentation period, and these effects were maintained till the end of the experiment. The results of the study revealed that better performance of broiler chickens were achieved when the chicks accessed the feed no longer than 48 h post-hatch
