Detection of genetic variation in bovine<i>CRY1</i>gene and its associations with carcass traits

Zoometrical index can be used to evaluate the performance of cattle. The present study aimed to detect the genetic markers for zoometrical index of cattle. Forty-five heads of mixed-sex cattle consisting of Bali (16), Madura (16), and Peranakan Ongole / PO (13) were collected from the breeding station for the experimental animals in this study. A Bovine 50K SNP BeadChip was used to explore genetic mutation in the autosomal chromosomes. Nine parameters of zoometrical index were evaluated in the present study. A TASSEL 5.0 software was used to evaluate 24,347 SNP markers. Research showed that two SNP Markers of ARS-BFGL-NGS-115374 (SNP1) and Hapmap28985-BTA-73836 (SNP2) had a significant association with zoometrical index in pool animals based on the Manhattan plot. The SNP1 had a significant association with the area index. Subsequently, a SNP2 significantly correlated with body ratio and over-increase index parameters. In addition, SNP1 is not located in the gene region. Meanwhile, SNP2 is located at the intron 5 region of the Cryptochromes circadian regulator 1 (CRY1) gene. However, this gene was polymorphic in Bos indicus cattle (Madura and PO). In conclusion, the CRY1 gene can improve the zoometrical index in Indonesian Bos indicus cattle (Madura and PO)

We analyzed the effects of Glycyrrhiza polysaccharide(GCP) on growth performance, appetite, and hypothalamic inflammation related indexes in broilers. One-day-old male AA broilers were randomly divided into four groups: Control, L-GCP, M-GCP, and H-GCP (0, 300, 600, and 900 mg GCP/kg feed), with six repetition cages for each treatment and twelve broilers in each repeat for a period of 42 days. From day 1 to day 21, the addition of GCP to the diet significantly improved the ADFI and the ADG of broilers, and the mRNA levels of NPY and AgRP were significantly increased while POMC and CART were decreased in the hypothalamus of broilers; GCP also significantly decreased the mRNA levels of IL-1β, IL-6, TNF-α, TLR-4, MyD88 and NF-κB, and increased the IL-4 and IL-10 in the hypothalamus from day 1 to day 42. The concentrations of appetite-related factors and inflammatory factors in serum were changed in the same fashion. Supplementation with 600 mg/kg GCP had the optimal effect in broilers, and GCP has the potential to be used as a feed additive in the poultry production industry.
