  Background and Objective: Feeding time restriction is an alternate, lower intensity type of feed restriction and is less stressful than other types. It is important to achieve beneficial effects from feed restriction without adverse effects on growth. This study aimed to determine the impact of feeding time restriction on growth performance of broiler chickens. Materials and Methods: Three hundred seven days old unsexed broiler chickens of the Lohmann commercial strain were used in a completely randomized design with 4 treatments and 5 replications. The treatments were the following: Broilers being fed ad libitum as a control group (P-0) and broilers having free access to feed during 9 h/day (P-1), 12 h/day (P-2) and 15 h/day (P-3). The feeding time restriction was done from 21-35 days of age. All data was analyzed based on a completely randomized design using SAS software. Results: Broilers had lower body weight gain, body weight and feed consumption due to feeding time restrictions P-1 and P-2, however, broilers that had access to feed during 15 h/day had a similar performance to broilers fed ad libitum. Feed conversion rates of broilers fed during 9 h/day were better than other treatments during the 1st week of feed restriction (21-28 days), however, there were no significant differences among the treatments during 29-35 days of age and the overall period of feed restriction (21-35 days of age). Conclusion: Broiler chickens with a feeding time restriction of free access to feed during 15 h/day during the grower period, had a similar performance at market age as broiler chickens with ad libitum feeding.

  Background and Objective: Feeding time restriction is an alternative lower-intensity feed restriction practice and could be less stressful than higher-intensity feed restriction practices. Feeding time restriction is more likely to provide the beneficial effects of feed restriction without adverse effects on growth. This study aimed to determine the effects of feeding time restriction on the growth performance of broiler chickens during the 35 days production period. Materials and Methods: Three hundred 1-day-old unsexed broiler chickens of the Lohmann commercial strain were used in a completely randomized design with 4 treatments and 5 replications. The treatments were as follows: broilers were fed ad libitum as a control group (P-0); broilers had free access to feed for 8 h day1 from 1-21 days of age and then were fed ad libitum from 22-35 days of age (P-1); broilers had free access to feed for 8 h day1 from 1-21 days of age and then for 12 h day1 from 22-35 days of age (P-2); broilers had free access to feed for 12 h day1 from 1-21 days of age and then were fed ad libitum from 22-35 days of age (P-3); and broilers had free access to feed for 12 h day1 from 1-35 days of age (P-4). Body weight and feed intake values were recorded weekly and body weight gains and feed conversion ratios were calculated. Two broiler chickens from each pen were used to measure the size of the carcass, abdominal fat pad and internal organs at 35 days of age. Results: At 21 day of age, the body weight and body weight gain values of the broilers that had feeding time restrictions (P-1, P-2, P-3 and P-4) were significantly lower than those of the broilers fed ad libitum (P-0). No significant effects of the feeding time restriction treatments on body weight gains were found during the growing period from 22-35 days of age but at 35 day of age, the P-3 broilers had no significant differences in body weight compared to the weight of the broilers fed ad libitum (P-0). At 21 day of age, feed intake values and feed conversion ratios in the feeding time restriction treatments were significantly lower than those in P-0. However, the P-2 and P-4 broilers had lower feed intake values and feed conversion ratios during the growing period at 35 day of age. There were no differences among the treatments in the weights of the carcass, abdominal fat pad and gizzard; however, the weights of the internal organs, such as the liver, small intestine and pancreas, were significantly increased in broilers that experienced smaller feeding time restrictions. Conclusion: Program for restricting feed for 12 h day1 from 1-21 days of age could be applied as a useful rearing management technique, resulting in a lower feed intake and no detrimental effects on the performance of broiler chickens.

  Background and Objective: Proteases are important enzymes and have high economic value due to their wide applications in the food industry as a meat tenderizer. Protease use in the food industry necessitates an understanding of the capabilities and influencing factors of these enzymes to accelerate enzymatic reactions. This study aimed to isolate and characterize the proteases of lactic acid bacteria (LAB) from Bekasam. Methodology: The samples were obtained from the third, fifth, seventh, ninth and eleventh day of fermentation to isolate the proteolytic LAB. Characterization of proteases includes the incubation time, casein substrate concentration, optimum temperature and pH, metal ion contents and stability. The LAB with the highest protease activity is identified molecularly and isolated through 16S rDNA sequencing and phylogenetic analysis based on the Neighbor Joining method. Results: The results showed that the best isolate was BAF-715 because it had the highest protease activity (18.84 U mL–1) at 40 h of incubation. The optimum activity of this protease on a casein substrate at 2.5% occurred at an incubation temperature of 40°C at pH 7 and in the presence of Mg2+ and Mn2+ (5 mM) as activators. Based on molecular DNA identification, the BAF-715 isolate is determined to be Pediococcus pentosaceus. Conclusion: A protease produced by Pediococcus pentosaceus showed the highest proteolytic activity, making it the best protease for application as a beef tenderizer.
