A study was conducted to investigate the effects of Bacillus amyloliquefaciens CECT 5940 as a direct-fed microbial (DFM) alone or in association with bacitracin methylene disalicylate (BMD) broilers under enteric pathogen challenge. total 1,530-day-old male Cobb500 chicks were randomly assigned 5 treatments, 9 replicate pens 34 birds each. Treatments included positive control (PC, basal diet without additives challenge); negative (NC, additive and challenged birds); NC + 0.05 g/kg BMD; 1 DFM...
A sanitary challenge was carried out to induce suboptimal herd health while investigating the effect of amino acids supplementation on piglet responses. Weaned piglets high status (6.33 ± 0.91 kg BW) were distributed in a 2 × factorial arrangement into two similar facilities with contrasting conditions and different diets. Our results suggest that increased Trp, Thr, Met dietary could support immune systems under challenge. In this manner, AA+ improved performance metabolism mixed management...
Abstract Highly intensified rearing conditions and precarious sanitary management predispose pigs to immune system activation, altered amino acid (AA) metabolism, decreased growth performance. Thus, the main objective of this study was evaluate effects increased dietary tryptophan (Trp), threonine (Thr), methionine + cysteine (Met Cys) supplementation on performance, body composition, responses group-housed growing under challenging conditions. A hundred twenty (25.4 ± 3.7 kg) were randomly...
This study investigated the effects of a low-protein diet with or without an increase in dietary protein and feed-grade amino acids (AAs) on growth performance, body composition, metabolism, serum acute-phase proteins finishing pigs reared thermoneutrality cyclic heat stress conditions. A total 90 gilts (67.7 ± 6.2 kg) were distributed 2 × 3 factorial arrangement (two ambient temperatures three diets). Ambient (AT) thermoneutral (TN, 22 °C for 24 h) (CHS, 12 h to 35 °C). The evaluated diets...
The impact of cyclic heat stress (CHS) and turning the lights on off pig feeding behavior (FB) was investigated. FB 90 gilts recorded in real-time under two ambient temperatures (AT): thermoneutrality (TN, 22 °C) or CHS (22/35 °C). day divided into four periods: PI (06–08 h); PII (08–18 PIII (18–20 PIV (20–06 h). Automatic Intelligent Precision Feeders each feed event for pig. An estimated meal criterion (49 min) used to calculate variables. Feed both ATs followed a circadian pattern....
A digestibility assay was conducted in order to determine the coefficients (DC) of amino acids feed ingredients cecectomized adult roosters. In total 48 roosters were used assess coefficient 7 ingredients: corn, soybean meal, concentrate, corn gluten wheat bran, peanut and feather meal. Each ingredient replicated six times a group 6 rooster measure endogenous acid losses. After hours fasting, tube fed 20g tested twice during day. At 12 hour-intervals excreta losses collected immediately...
SUMMARY The objective of this study was to evaluate the performance male colonial chickens fed diet supplemented with commercial probiotic (Calsporin ®). A total 210 chicks Label Rouge lineage were used and they raised in experimental shed up 30 days old. These birds had free access pickets Tifton-85, from 31-90 age. design completely randomized, two treatments, one containing feed Bacillus subtillis (300 g t-1 1×109 UFCg-1) another without it, ten replications per treatment, consisting 21...
Abstract This study evaluated the effects of increased dietary Thr, Met and Trp supplementation on fecal microbiota composition weaned piglets raised under contrasting sanitary conditions [(GOOD SC) or mixed management poor housing (MM+POOR SC)] during nursery phase. A total 144 entire male [body weight (BW) = 6.33 ± 0.91 kg] from a high status (HSS) farm were randomly housed following 2×2 factorial arrangement regarding BW blocks. Factorial was composed two SC (GOOD MM+POOR) diets [control,...
Abstract Recent insights continue to point a causal role of the gastrointestinal (GI) microbiome in digestion, nutrient absorption, and host metabolism. The GI may be frequent target perturbation since some challenges (i.e., high density, temperature air quality fluctuations, presence endemic enteric pathogens) faced by pigs altogether create spectrum contrasting sanitary conditions. Therefore, our study investigated influence increased dietary tryptophan, threonine, methionine...
The impact of cyclic heat stress (CHS) and lighting events on pig feeding behavior (FB) was investigated. FB 90 gilts recorded in real time under two ambient temperatures (AT): thermoneutrality (TN, 22 °C) or CHS (22°/35 °C). day divided into four periods: PI (06-08 h); PII (08-18 PIII (18-20 PIV (20-06 h). Automatic Intelligent Precision Feeders each feed event for pig. An estimated meal criterion (49 minutes) used to calculate the variables. Feed both ATs followed a...
Emulsifiers in animal diets are an interesting and effective strategy for nutritionists to improve the digestion of dietary lipids and, consequently, provide better performance. This study aimed evaluate effect supplementation with emulsifier based on mono- diglycerides (120 g t-1 feed) associated different energy levels (2,775; 2,725; 2,675 2,625 kcal metabolizable kg-1 performance egg quality Hisex Brown laying hens. The hens were distributed 50 experimental plots eight birds each. A...
