Nutrient digestion efficiency: a comparison between broiler chickens and growing pigs fed maize, barley, and oats-based diets with an emphasis on starch.

We investigated the hypotheses that broilers and pigs have distinct starch digestion capacities, and that different cereals could trigger diet-species interactions. Ten replicates of 2 broilers (14-d-old) or 1 pig (50-d-old) each were distributed into a 3x2 randomized factorial design with 3 pelleted diets (maize, barley, or oat-based) and the 2 species. Nutritional composition was equal for both species.

Novel thermal stability enhanced xylanase improves the performance and digestibility parameters in broilers.

Xylanases require thermal stability to withstand the pelleting process, pH stability to function in the gastrointestinal tract, and resistance to xylanase inhibitors in raw materials to be effective in animal feed. A GH11 family xylanase originating from an anaerobic fungus, Orpinomyces sp. strain PC-2, has high specific activity and resistance to xylanase inhibitors intrinsically.

Combination of emulsifier and xylanase in triticale-based broiler chickens diets.

The current study aimed to investigate the effect of supplementing an emulsifier, xylanase or a combination of both on the growth performance, digestibility of nutrients, microflora activity and intestinal morphology in broiler chickens fed triticale-based diets. A total of 480 one-day-old male Ross 308 broiler chicks were randomly assigned to four dietary treatments: control (CON), control with an added emulsifier (EMU), control with added xylanase (ENZ) and control with emulsifier and xylanase (EMU+ENZ). Xylanase supplemented groups had diminished feed intake (FI) and enhanced body weight gain (BWG) only within the starter period ( ≤ 0.

A total of 384 male broiler chicks were assigned to four dietary treatments. The diet of the control treatment (CON) consisted of soybean, maize, and RSM (5% in starter, 7% in grower, 15% in finisher) with soybean and palm oils.

Effect of Fasting on the Spexin System in Broiler Chickens.

Spexin (SPX) is a highly conservative peptide hormone containing 14 amino acids and was discovered in 2007 by bioinformatics methods. However, nothing is yet known about its role in the metabolism of birds, including broilers. The aim of this study was to investigate the effect of short-term fasting (2, 4, and 8 h) on the concentration of SPX in blood serum and the expression levels of the genes encoding this peptide () and its receptors, GALR2 and GALR3, in the tissues involved in carbohydrate and lipid metabolism (muscles, adipose tissue, and liver).

Emulsifier and Xylanase Can Modulate the Gut Microbiota Activity of Broiler Chickens.

In this study, we aimed to investigate the effect of xylanase (XYL), emulsifier (EMU), and a combination of both (XYL + EMU) in wheat diet with a high level of tallow on gastrointestinal tract microbiota activity, excretion of sialic acids, and selected gut segments morphology of 480 one-day-old male ROSS 308 broiler chickens. The activities of bacterial enzymes in the ileal digesta were lower in experimental groups compared to the control (CON) group. Enzyme activity in the cecum was significantly higher than in the ileum.

Growth performance and Carcass quality in broiler chickens fed on legume seeds and rapeseed meal.

The aim of this study was to compare the growth performance parameters, carcass quality, and meat traits in broiler chickens fed on diets containing legume seeds and rapeseed meal as an alternative to soybean meal. In this study, 448 male ROSS 308 chicks were divided into subgroups: a control group (I) fed on soybean meal (SBM), and six experimental groups II-rapeseed meal (RSM); III-white lupin (WY); IV-yellow lupin (YL); V-narrow-leaved lupin NLL; VI-pea (Pe); and VII-faba bean (FB). After 42 days of rearing, 10 birds from each group were slaughtered and dissected.
