The current study evaluated the effect of a commercial wheat-maizesoybean meal based diet supplemented with an organic acid product containing a specific combination of formic and propionic acids (pHorce) on performance parameters in broiler chickens. One day-old broiler chickens (Ross 308) were randomly allotted to 2 treatments with 10 replicate cages/treatment and 2 birds/cage from d 1 to 21....

Two independent experiments were conducted with male Cobb × Cobb 500 broilers to determine the optimal valine-to-digestible-lysine ratio for broiler development. We conducted a randomized block experiment with 7 treatments, each with 8 replicates of 25 starter birds (8 to 21 d of age) and 20 finisher (30 to 43 d of age) birds. To prevent any excess of digestible lysine, 93% of the recommended l...

Currently, the genome sequencing community is producing shotgun sequence data at a very high rate, but finishing (collecting additional directed sequence data to close gaps and improve the quality of the data) is not matching that rate. One reason for the difference is that shotgun sequencing is highly automated but finishing is not: Most finishing decisions, such as which directed reads to obt...

The present study was conducted to evaluate the effect of the dietary supplementation of Bacillus amyloliquefaciens-based direct-fed microbial (DFM) on growth performance, nutrient utilization, intestinal morphology and cecal microflora in broiler chickens. A total of two hundred and eighty eight 1-d-old Arbor Acres male broilers were randomly allocated to one of four experimental treatments in...

A total number of 540, one day old of commercial broiler chicks were used to study the effect of selenium (Se) and cadmium (Cd) separately and in mixture on broiler chicks' performance (from one day to 49 days of age). Birds were distributed randomly into 18 dietary treatments groups, each groups represented by triplicate pens (10 chicks each) until the end of the experiment (49 days of age). T...

Two experiments were conducted to determine the nutritive value of copra meal for grower and finisher pigs (40–95 kg). 21 The apparent nutrient digestibility of copra meal, when included at 200 and 400 g kg in the diet of both the grower and finisher pig, was determined in experiment 1. In experiment 2, productive performance was determined in group fed pigs 21 (n 5 360) offered diets ad libitu...

A growth performance and carcass evaluation study was conducted to determine the maximal inclusion rate of corn distillers dried grain with solubles (DDGS) in grower-finisher pig diets when formulated on a total AA basis. A total of 240 (28.4 +/- 0.8 kg of BW) crossbred pigs [(Yorkshire x Landrace) x Duroc] were allotted randomly within sex and weight outcome groups to 1 of 24 pens. Pens were a...

A total of 252 crossbred pigs were used in two experiments to determine the effect of feeding hydrolyzed feather meal (FM) during the growing-finishing period on animal performance, carcass composition, and pork quality. All pigs were blocked by weight, and dietary treatments were assigned randomly to pens within blocks. In Exp. 1, 24 pens were randomly assigned to one of three dietary treatmen...

AIM The aim was to investigate the effects of dietary supplementations of prebiotic, probiotic, and synbiotic on growth performance and carcass characteristics of broiler chickens. MATERIALS AND METHODS A total of 360 1-day-old Vencobb broiler chickens of either sex were randomly assigned to four dietary treatments each consisting of three replicates and each replicate having 30 birds for 6 w...

Abstract Animal welfare is of increasing public interest, and the pig industry in particular subject to much attention. The aim this study was identify compare areas animal concern for commercial pigs four different production stages: (1) gestating sows gilts; (2) lactating sows; (3) piglets; (4) weaner-to-finisher pigs. One assessment protocol developed each stage, comprising between 20 29 mea...
