Bacterial Succession in the Broiler Gastrointestinal Tract.
A feeding trial was performed with broilers receiving a diet of wheat-based feed (WBF), maize-based feed (MBF), or maize-based concentrates supplemented with 15% or 30% crimped kernel maize silage (CKMS-15 or CKMS-30, respectively). The aim of the study was to investigate the bacterial community compositions of the crop, gizzard, ileum, and cecum contents in relation to the feeding strategy and...
متن کاملEffect of Some Acidifiers on Gastrointestinal Tract Characteristics and Performance of Broiler Chickens
The effects of Selko-pH (S; 1 mL/L drinking water); Termin-8 (T; 2 kg/ton feed) and Neogermicin (N; 2 L/ton feed) on gastrointestinal tract (GIT) pH, microbial population, ileal digestibility and broiler performance were investigated. The lowest feed intake (FI) was attained by chickens fed diets supplemented with S group in all periods (P
متن کاملEffects of dietary supplementation of waste date’s vinegar on performance and improvement of digestive tract in broiler chicks
Two hundred 1-day-old commercial broilers (Ross 308) were used to determine the effects of diets supplementation with waste date’s vinegar (WDV) on the growth and performance of digestive tract over a 42-days growing period. Chicks were randomly allocated to one of five experimental diets supplementing as 0 (control), 1, 2, and 3% of WDV and 2% industrial vinegar (IV). Broilers and their feed c...
متن کاملEffect of long-term oral administration of thyroxine on morphology of the gastrointestinal tract in broiler breeder hens
Published data on 4-week-long administration of extra thyroxine (T4) in broiler breeder hens to alleviate the cold-induced ascites in their offspring suggested that long-term maternal hyperthyroidism would affect the gastrointestinal tract morphology. Broiler breeder hens (n=70) were reared in individual cages and allotted to control and hyperthyroid groups (five replicates of seven ...
متن کاملScreening for bacillus isolates in the broiler gastrointestinal tract.
Spores from a number of different Bacillus species are currently being used as human and animal probiotics, although their mechanisms of action remain poorly understood. Here we describe the isolation of 237 presumptive gut-associated Bacillus spp. isolates that were obtained by heat and ethanol treatment of fecal material from organically reared broilers followed by aerobic plating. Thirty-one...
