Abstract ▼ AI-Helper

Objective: This experiment studied the effects of first feed intake time post-hatch on growth performance, nutrient apparent metabolic rate and intestinal digestive enzyme activities in broilers. Methods: Two thousand five hundred and twenty LingNan Yellow broilers were randomly allotted to seven treatments with six replicates of 60 each. The only experimental factor was the first feed intake time which was 18, 24, 30, 36, 42, 48, and 54 hours after hatching. The whole experiment lasted for 21 days. Results: During the whole period, the 30 h treatment had the best body weight and average daily gain (p<0.05), followed by the 24 h group performance optimization. Also, the 30 h group was observed to have the best apparent metabolic rate for ether extract (p<0.05) and crude protein (p<0.05) and the highest activities of amylase, lipase and trypsin in small intestine. And the 24 h group was second only to the 30 h group in terms of the above two measures. Conclusion: These results indicated that the appropriate first feeding time of LingNan Yellow broilers was 24 to 30 hours after hatching.

After three days’ adjustment period, a four-day formal experiment was conducted.
This paper explored nutrient apparent metabolic rate and intestinal digestive enzyme activities in broilers, the effects of different first feeding times on growth performance, and the optimal time for first feeding in broilers. And for the first time, this research viewed the effects of first feeding time on growth performance from the angle of apparent metabolic rate of nutrients in broilers.
After three days’ adjustment period, a four-day formal experiment was conducted. For the determination of EE and CP metabolism, excreta from each replicate were collected at 09:00 am and 16:00 pm every day. After freeze-drying, extra samples were ground to pass through a 40-mesh screen and then analyzed for CP and EE according to GB/T6432-1994 and GB/T6433-2006.
Mortality was checked and recorded daily by each replicate respectively, and then the date of death and BW of chicks were recorded. In addition, the following data were collected and calculated on day 1, 7, and 21 of the experimental period: BW, average daily gain (ADG), average daily feed intake (ADFI) and gain:feed. On day 4, 7 and 21, 4 chickens from each replicate respectively were randomly selected to be slaughtered for sampling after 12-h fasting (water offered ad libitum).
It was possible, therefore, that the increase of digestive enzyme activity in the small intestine promoted the absorption and utilization of nutrients and increased the apparent metabolic rate of EE and CP, leading to higher ADG, ADFI, and gain:feed. This may be the reason why the appropriate start feeding time, which was from 24 to 30 hours in this study, improved broiler performance.
However, few studies were established to explore the apparent metabolic rate of nutrients and its relationship with intestinal enzymes. This paper explored nutrient apparent metabolic rate and intestinal digestive enzyme activities in broilers, the effects of different first feeding times on growth performance, and the optimal time for first feeding in broilers. And for the first time, this research viewed the effects of first feeding time on growth performance from the angle of apparent metabolic rate of nutrients in broilers.

In conclusion, this experiment indicated that it was not beneficial for newly hatched chicks to be exposed to exogenous feed as soon as possible. On the contrary, feeding untimely and prematurely could cause negative effects.
The AMS, lipase and trypsin enzyme activities of the 30 h group in duodenum, jejunum and ileum were the highest (p<0.05), but AMS enzyme activities in duodenum and ileum was the best in the 24 h group (p<0.05).
And the 54 h group had the lowest concentration of AMS. The results of lipase and trypsin were similar to the result of AMS, almost all of them reached the maximum at 30 h group, followed by 24 h group. Besides, the results of 7 day and 21 day also suggested that 24 h group and 30 h group were the best two treatments.
And Careghi et al [15] demonstrated a positive curvilinear relationship between percentage of chick weight loss and holding time. The results of this study showed that the BW and ADG of broilers fed at 30 h post-hatch were both signifi cantly higher than those of other groups at 7 d of age, and the smallest BW and ADG were observed at the 54 h group. In addition, there was no significant difference between the 24 h and 30 h group in terms of BW and ADG.
