Effects of Artemisia annua L. Water Extract on Growth Performance and Intestinal Related Indicators in Broilers.
Artemisia annua L. is a natural herb with a variety of bioactive substances, which can play a variety of biological functions such as anti-inflammatory, antioxidant, antibacterial and antiviral, and can be used as a potential feed additive. The purpose of this study was to investigate the effects of different doses of Artemisia annua L. water extract (AAWE) on growth performance and intestinal related indicators in broilers. A total of 200 one-day-old Arbor Acre broilers were selected and randomly divided into five treatment groups, with five replicates in each group and eight birds per replicate. The control group was fed a basal diet, whereas the other groups were fed a basal diet supplemented with 0.5, 1.0, 1.5, or 2.0 g/kg AAWE. On d 21, with the increase in AAWE dose, final body weight and feed efficiency showed a quadratic increase effect, whereas feed intake showed a linear reduction effect; however, the apparent metabolic rate of dry matter, crude protein, and ether extract increased quadratically on d 42. In addition, the activity of duodenal chymotrypsin and trypsin, and of jejunal lipase quadratically increased, whereas the intestine crypt depth linearly decreased on d 42. The number of total anaerobic bacteria increased quadratically, whereas the number of Escherichia coli decreased quadratically. The number of Lactobacillus increased linearly, whereas H2S emission linearly decreased on d 21; moreover, NH3 emission (24 h) quadratically decreased on d 42. In conclusion, AAWE promoted the growth performance and intestinal related indicators of broilers.
期刊介绍:
The Journal of Poultry Science will publish original reports and reviews which either make an original contribution to fundamental science or are of obvious application to the industry. Subjects which are covered include: breeding and genetics, nutrition and feeds, physiology, reproduction, immunology, behavior, environmental science, management and housing welfare, processing and products, and health in poultry. Submission of original articles to the Journal is open to all poultry researchers. The review articles are invited papers written by international outstanding researchers. Articles will be published in English, American style.
