Analysis of carcass and meat quality traits and nutritional values of hybrid wild boars under different crossing systems

S. - H. Zhang, Shen, L. - Y., Luo, J., Wu, Z. - H., Jiang, Y. - Z., Tang, G. - Q., Li, M. - Z., Bai, L., Li, X. - W., and Zhu, L., Analysis of carcass and meat quality traits and nutritional values of hybrid wild boars under different crossing systems, vol. 14, pp. 2608-2616, 2015.

The aim of this study was to analyze the results of two crossing systems between wild boars and different domesticated pig breeds. Hybrid wild boars were produced by crossing captured wild boars with Meishan pigs and LY sows according to the traditional production system. The resultant commercial hybrids were black and white in coat color, respectively. Significant differences were found in the carcass and meat quality traits and nutritional values between these two hybrid wild boars.

Evaluation of DNA polymorphisms involving growth hormone relative to growth and carcass characteristics in Brahman steers

V. R. Beauchemin, Thomas, M. G., Franke, D. E., and Silver, G. A., Evaluation of DNA polymorphisms involving growth hormone relative to growth and carcass characteristics in Brahman steers, vol. 5, pp. 438-447, 2006.

Associations of DNA polymorphisms in growth hormone (GH) relative to growth and carcass characteristics in growing Brahman steers (N = 324 from 68 sires) were evaluated. Polymorphisms were an Msp-I RFLP and a leucine/valine SNP in the GH gene as well as a Hinf-I RFLP and a histidine/arginine SNP in transcriptional regulators of the GH gene, Pit-1 and Prop-1. Genotypic frequencies of the GH SNP, Pit-1 RFLP, and Prop-1 SNP were greater than 88% for one of the bi-allelic homozygous genotypes.

Associations of DNA polymorphisms in growth hormone and its transcriptional regulators with growth and carcass traits in two populations of Brangus bulls

M. G. Thomas, Enns, R. M., Shirley, K. L., Garcia, M. D., Garrett, A. J., and Silver, G. A., Associations of DNA polymorphisms in growth hormone and its transcriptional regulators with growth and carcass traits in two populations of Brangus bulls, vol. 6, pp. 222-237, 2007.

Sequence polymorphisms in the growth hormone (GH) gene and its transcriptional regulators, Pit-1 and Prop-1, were evaluated for associations with growth and carcass traits in two populations of Brangus bulls Chihuahuan Desert Rangeland Research Center (CDRRC, N = 248 from 14 sires) and a cooperating breeding program (COOP, N = 186 from 34 sires). Polymorphisms were SNP mutations in intron 4 (C/T) and exon V (C/G) in GH, A/G in exon VI in Pit-1, and A/G in exon III in Prop-1.
