Selection of fecal enterococci exhibiting tcrB-mediated copper resistance in pigs fed diets supplemented with copper.
Copper, as copper sulfate, is increasingly used as an alternative to in-feed antibiotics for growth promotion in weaned piglets. Acquired copper resistance, conferred by a plasmid-borne, transferable copper resistance (tcrB) gene, has been reported in Enterococcus faecium and E. faecalis. A longitudinal field study was undertaken to determine the relationship between copper supplementation and ...
متن کاملAmino acid supplementation of hydrolyzed feather meal diets for finisher pigs.
The objective of this study was to determine the possibility of replacing soybean meal (SBM) in finisher pig diets completely with hydrolyzed feather meal (FM). Forty-five gilts and 45 castrated males (57.8+/-0.8 kg of BW; 3 gilts or 3 castrated males/pen) were randomly assigned to 5 finisher-1 diets with 6 pens per diet. At an average pen BW of 81.0+/-1.4 kg, pigs were offered finisher-2 diets...
متن کاملSupplementation of barley-based diets with β-glucanase for pigs: energy and amino acid digestibility response.
An experiment was conducted to determine the effect of graded levels of β-glucanase supplementation to barley (Hordeum vulgare)-based diets on the digestibility of DM, GE, N, and AA for growing-finishing pigs. Eight pigs (initial BW: 53.3 ± 3.2 kg) were each fitted with a simple T-cannula at the distal ileum and allotted to a replicated 4 × 4 Latin square design with 4 diets and 4 periods in ea...
متن کاملEnzyme supplementation and particle size of wheat in diets for nursery and finishing pigs.
Three experiments were conducted to determine the effects of enzyme supplementation and particle size of wheat-based diets on growth performance and nutrient digestibility in nursery and finishing pigs. In Exp. 1, 180 weaned pigs (5.7 kg and 21 d of age) were fed diets in a 35-d growth assay without or with a Trichoderma longibrachiatium enzyme product (4,000 units of xylanase activity per gram...
متن کاملResponses of pigs to Aspergillus niger phytase supplementation of low-protein or high-phytin diets.
Growth and N utilization responses of pigs to Aspergillus niger phytase supplementation of low-protein or high-phytin diets were examined in 2 experiments. In the first experiment, 6 diets arranged in a 3 x 2 factorial with Aspergillus niger phytase at 0, 600, or 1,200 units/kg and dietary protein at 160 or 200 g/kg; and 12 pigs (growth) or 6 pigs (N utilization) per diet were used to test the ...
