To evaluate the impact of micelle silymarin (MS) on fattening pig growth, nutrient digestibility, toxic gas emissions and meat quality, 140 crossed fattening pigs were allocated to four treatments with seven repetition pens [(two barrows and three gilts)/pen] per treatment from the initial body weight of 51.0 kg (SD 2.86). The pigs were fed the basal diet containing 0%, 0.05%, 0.1%, and 0.2% MS for 10 weeks. The results showed a linear improvement in the average daily gain (ADG) of pigs during 5 to 10 weeks as the dietary MS dose increased (P = 0.041). The apparent total tract digestibility of nitrogen (N) was enhancive linearly...

The Inner Mongolia cashmere goat is famous for its bright white cashmere fibre. However, little attention is given to the excellent characteristics of this breed's meat. We used label-free proteomics to analyse the total protein content in five different muscles, and 1 227 proteins were detected. Through sequential windowed acquisition of all theoretical fragment ions (SWATH), 16, 33, 49, 39, and 31 differentially expressed proteins were successfully detected in the five muscles. Protein-protein interaction network analysis of differentially expressed proteins revealed many strong interactions related to fatty acid beta oxidation and muscle development....

The aim of the present research was to evaluate the effect of feeding graded levels of whole barley (WB) on broiler chicken growth and carcass performance, gastrointestinal morphology, and function. A total of 800 male Ross 308 broiler chickens (1-day-old) were randomly assigned to four treatment groups with four replicate pens of 50 birds each. Diets differed in their WB dosage: without WB (NO-WB); low WB amount (LOW-WB) dosages: 4% (1-7 days of age), 8% (8-21 days of age), 15% (22-35 days of age); medium WB amount (MEDIUM-WB) dosages: 6% (1-7 days of age), 12% (8-21 days of age), 20% (22-35 days of age); high WB amount (HIGH-WB) dosages: 8% (1-7...

The Sox transcription factor family plays an important role in various biological processes such as animal sex determination and multiple organ development. We used online databases to analyze the gene structure, chemical characteristics, and evolutionary relationship of Sox family genes through bioinformatics, and we studied the expression profiles and regulatory mechanisms of Sox family genes. A total of 29 rainbow trout Sox genes were identified. The phylogenetic analysis found that Sox genes of rainbow trout were clustered in seven subfamilies (B1, B2, C, D, E, F and H), and the gene structure of each...
