The aim of this study was to evaluate the effects of sodium butyrate (SB) on growth performance and development of digestive and immune organs in broilers. Dietary treatments had similar compositions but with 0%, 0.03%, 0.06%, and 0.12% SB substituted (weight/weight) for identical amounts of the basal diet. SB supplementation linearly increased (P < 0.05) average daily gain for each period, except for days 15-21. SB supplementation linearly increased (P < 0.05) the relative weight of proventriculus (day 7), gizzard (days 7 and 14), duodenum (days 21 and 28), jejunum (day 21), ileum (day 21), small intestine (day 21), rectum...

We analysed the correlations of milk fermentability (yogurt test acidity), renneting (time to rennet coagulation of milk protein) and results of ethanol tests (indirect indicator of milk thermostability) with the percentages of the milk components. The correlations of the milk component percentages with renneting were mostly weak, while the correlations with the ethanol test were even poorer. The CSN3 and LGB genotypes did not show a significant interaction in their influence on milk fermentability, renneting or ethanol test results. For the ethanol test, many significant interactions were observed between the DGAT1, LEP,...

The present study aimed to investigate the effect of probiotic lactic acid bacteria (LAB) addition on Listeria monocytogenes translocation and its toxin listeriolysin O (LLO), proinflammatory factors, immune organ indexes and serum immunoglobulins in farmed rabbits. Five treatments included negative control (NC), positive control (PC) with L. monocytogenes infection and supplemental LAB at 3.0 × 106 (low-LAB, L-LAB), 3.0 × 108 (medium-LAB, M-LAB) and 3.0 × 1010 (high-LAB, H-LAB) CFU/kg of diet, respectively. The LAB was a mixture of equal amounts of Lactobacillus acidophilus (ACCC11073),...

FAT atypical cadherin 1 (FAT1) is a member of the atypical cadherin superfamily and is involved in the planar cell polarity signalling pathway which regulates hair follicle morphogenesis, cycling, and orientation. The purpose of this study was to investigate the sheep FAT1 gene expression, polymorphisms and its association with wool quality traits in Chinese Merino sheep. Quantitative real-time PCR analysis showed that the FAT1 mRNA was differentially expressed in the adult skin of Chinese Merino and Kazak sheep. Seven SNPs (termed SNPs 1-7) were identified in exon 2 of sheep FAT1 gene by Sanger sequencing. SNPs 2 and 7 (novel...
