Effects of bovine colostrum on performance, survival,and immunoglobulin status of suckling piglets during the first days of life
bovine colostrum supplement growth performance field trial nursery pig survivability
<
2015/9/15
Supplementation of bovine colostrum (BC) has shown to improve growth performance, intestinal development, and immune response in early-weaned pigs. Little is known about whether BC may have similar ef...
Optimum proportion of standardized ileal digestible sulfur amino acid to lysine to maximize the performance of 25–50 kg growing pigs fed reduced crude protein diets fortified with amino acids
amino acid ratio requirement
<
2015/7/28
The study was conducted to determine the standardized ileal digestible (SID) sulfur amino acid
(SAA) to lysine (Lys) ratio required to maximize the performance of 25–50 kg pigs fed reduced crude pro...
Effect of source of methionine in broken rice-soybean diet on production performance, blood chemistry, and fermentation characteristics in weaned pigs
short-chain fatty acids piglets
<
2015/7/7
The population of Lactobacillus spp. in the caecum was decreased
by both DLM and LMA supplementation (P < 0.05). Succinic acid concentration in the caecum of pigs fed the
DLM diet was greater than...
Fermented liquid feed for weaned piglets: impact of sedimentation in the feed slurry on performance and gut parameters
performance gut flora gut morpho-histology
<
2015/7/7
It was assumed that these poorer results were due to sedimentation of the solids in the FLF and therefore a
second experiment was conducted with sepiolite (10 g/kg) added to the feeds. Sepiolite ten...
Effect of synbiotic dietary supplementation on survival, growth performance, and digestive enzyme activities of common carp (Cyprinus carpio) fingerlings
probiotic growth survival digestive enzyme
<
2015/7/7
The results showed that synbiotic could significantly enhance growth parameters (weight gain, length gain,
specific growth rate, percentage weight gain) (P < 0.05), but did not exhibit any effect on...
Energy content and amino acid digestibility of extruded and dehulled-extruded corn by pigs and its effect on the performance of weaned pigs
digestible energy extrusion processing growth
<
2015/7/3
Three experiments were conducted to compare raw corn, extruded corn, and dehulled-extruded corn in piglets’ feeding. In Experiment (Exp.) 1, 8 barrows (19.9 ± 0.6 kg) were fed experimental diets conta...
The effect of non-phytate phosphorus and phytase levels on performance, egg and tibia quality, and pH of the digestive tract in hens fed higher-calcium-content diet
mineral nutrition laying hen egg production
