Special Issue Information
Dear Colleagues,
The aim of this Special Issue is to publish high-quality papers on poultry nutrition and the inter-relations between nutrition, metabolism, gut microflora, and poultry performance. Therefore, I invite the submission of recent findings, in the form of original research articles or reviews, on poultry nutrition in such areas as:
- the nutrient requirements of poultry;
- the impact of dietary fibre on poultry health and performance;
- the use of feed additives to improve gut microflora and performance;
- the effect of feeding on poultry meat end egg quality;
- assessing factors that cause variation in feed ingredients used in poultry diets;
- alternative feed ingredients for use in poultry feed formulations;
- the influence of gastrointestinal pH on nutrient bioavailability and the intestinal microbiota in poultry;
- evaluating phytate and xylan ‘susceptibility’ to the effects of enzymes;
- assessing factors that influence reactivity and enzyme efficacy;and
- developing in vitro models to determine the digestibility of poultry diets.

Abstract: This paper investigated effects of heat stress on gut-microbial metabolites, gastrointestinal pep-tides, glycolipid metabolism and performance of broilers. Thus, 132 28-day-old Arbor Acres broilers were randomly distributed to two treatments:thermoneutral control (TC, 21℃) and high temperature (HT, 31℃). The results showed that the average (ADG), average (ADFI), feed conversion ratio (FCR) and gastric inhibitory polypeptide (GIP) concentration in the jejunum sig-nificantly decreased(P<0.05), the core temperature, ghrelin in hypothalamus and cholecystokinin (CCK) in jejunum and serum significantly increased(P<0.05)in HT group. Exploration the structure of cecal microbes is accomplished by sequencing 16S rRNA genes. The sequencing re-sults showed that the proportion of Christensenellaceae and Lachnospiraceae decreased signifi-cantly (P<0.05) whereas the proportion of Peptococcaceae increased at the family level. Rumino-coccus and Clostridium abundances were significantly increased at the genus level. Furthermore, the content of acetate in the HT group was significantly increased. Biochemical parameters showed that the blood glucose concentration of the HT group was significantly decreased, and the TG (serum triglycerides), TC (total cholesterol), insulin concentration and the insulin re-sistance index were significantly increased. Nonesterified fatty acid (NEFA) in the HT group de-creased significantly. In conclusion, the results of this paper suggest that the poor production per-formance of broilers under heat stress may be related to short-chain fatty acids (SCFAs) ferment-ed by intestinal microbiota involved in regulating metabolic disorders.
