Piglets experience stresses that impact intestinal homeostasis and result in a high incidence of diarrhoea and reduced growth performance during weaning. Recent studies have indicated that gastrointestinal tract microbiota can be nutritionally regulated in ways that can benefit and promote…
This study was developed to examine the performance, carcass and cut yields, nutrient digestibility, and intestinal histomorphometry of chickens fed diets supplemented with protected sodium butyrate until 21 days of age. Two experiments were conducted, both of which involved the…
Effects of protected sodium butyrate (PSB) in broiler diets with reduced metabolizable energy (ME) content on production performance, intestinal histomorphometry and nutrient metabolizability were evaluated in two experiments. In one experiment, 384 one-day-old male chicks with an average weight of…
Two experiments were conducted to evaluate the effect of including protected sodium butyrate (PSB) in the diets of laying hens of advanced age on productive performance and egg quality. In experiment 1, a total of 320 Dekalb White 61-week-old laying…
The effects of organic acid, probiotic and a combination of the two on performance and gut morphology in broiler chickens were investigated. Two hundred and forty one-day-old Arbor Acre broiler chicks were randomly assigned to five dietary treatments with six…
Four commercial organic acids and a reference antibiotic, Neoxyval, were administered to commercial broilers to evaluate the efficacy of these products during pre- and post-challenge with Salmonella enterica subsp. enterica Typhimurium (S. Typhimurium) on selected indicators of their antioxidant status…
This article summarizes experimental knowledge of the efficacy, modes of action and applications of herbal extracts and organic acids as feed additives for pigs. Herbal extracts comprise a wide variety of herbs, spices and, most importantly, essential oils. Organic acids,…
In order to investigate the effects of organic acids, prebiotics and probiotics on broiler chickens, a total of 288 day-old male Cobb chicks were distributed in a completely randomized design according to a 2 × 4 factorial, consisting of two…
