An in silico approach was developed to survey the genes expressed in four internal organs of pig: liver, kidney, spleen and small intestine. The major procedures of the approach included: (1) BLAST se...
A total of 140 weaning pigs were used to determine the effects of digestive enzyme supplementation to corn-soybean meal diets on growth performance, physiological changes of small intestine, microorga...
Copper-bearing montmorillonite (Cu-MMT) was produced by Cu2+ cation exchange reaction. X-ray diffraction analysis showed that that the (001) basal spacing of the MMT crystal lattice increased from 1.5...
Ninety six growing pigs (Duroc횞Landrace횞Jia) were used to investigate the effects of betaine on growth, nutrient utilization, carcass composition and meat quality at different levels of ...
A total of 96 growing barrows (Duroc횞Landrace횞Yorkshire) at an average BW of 20.2 kg were used to investigate the effects of montmorillonite (MMT) or copper-bearing montmorillonite (Cu-M...
The study was conducted to evaluate the effects of montmorillonite nanocomposite (MNC) on mercury residues in growing/finishing pigs. A total of 96 cross bred pigs (Duroc Landrace large white, 48 barr...
Humic substances include several biological active and inactive compounds that are commonly used for improving soil fertility. Use of humic substances in swine diets is a novel concept. Humic substanc...
Quantitative trait loci (QTL) mapping can be applied to detect chromosomal locations that control economic traits in farm animals. Teat number has been considered as one of the most important factors ...
In order to detect the molecular mechanism of heterosis in pigs, the mRNA differential display technique was performed to investigate the differences in gene expression of pig''''s Longissimus dorsi b...
In Exp. 1, a total of 36 pigs (6.55 0.10 kg average initial body weight and 21 d average age) were used in a 14 d growth study to determine the effects of replacing spray-dried plasma protein (SDPP) w...
The objective of this study was to investigate the effects of different sources of Ca and P on urine and ileal digesta pH, and ammonia (NH3), methane (CH4), and odor emission. In experiment 1, eight p...
Lectin activities and chemical characteristics of Escherichia coli, Lactobacillus spp. and Bifidobacterium spp. originating from the porcine cecal mucosal layer were studied based on hemagglutination ...
An experiment was conducted to investigate the effect of microbial phytase (Natuphos ) supplementation in combination with enzyme complex (composed of enzymes targeted to SBM dietary components such a...
A repeated 4 4 Latin square design was conducted with eight ileal cannulated castrates to examine the effect of source of starch and fiber on nutrient balance and energy metabolism. Pigs were fed on o...
The polymorphism of the locus FSHRB in intron6-Exon7 of FSHR gene was investigated by PCR-RFLPs in Erhualian, Large White and Landrace Large White; The association of polymorphism and litter size was ...
