Margherita, S. S. (University of California, Davis) and R. E. Hungate. Serological analysis of Butyrivibrio from the bovine rumen. J. Bacteriol. 86:855-860. 1963.-The cultural and fermentation characteristics of a number of strains of Butyrivibrio fibrisolvens isolated from the bovine rumen of cattle from different areas were determined, and the strains were subjected to serological analysis by...

In cattle, phenotypic expression of reproductive traits occurs late in life. The identification of causal mutations in genes affecting reproduction permits the inclusion of these SNPs in customized DNA chips to increase accuracy. Therefore, the aim of this study was to detect causal mutations in the TOX and NCOA2 genes previously identified by genome-wide association studies of zebu cattle. DNA...

Abstract The aim of this study was to estimate the influence heterosis and breed percentage on birth weight (BW) weaning (WW) in beef cows a tropical environment. Data from 900 calves 2,843 individuals pedigree, multibreed herd Panama Agricultural Innovation Institute (IDIAP) Gualaca, were used. comprised following genetic groups according their percentage: adapted Brahman (BR), Nellore (Ne), U...

ENETICALLY controlled differences in the p-globulins of British breeds of Gdairy cattle have been described by SMITHIES and HICKMAN (1958) and ASHTON (1958). GIBLETT, HICKMAN and SMITHIES (1959) showed that these ,@globulins are transferrins. The same transferrin differences have been described in Swedish cattle (GAHNE, RENDEL and VENGE 1960) and in Danish cattle ( H~JGAARD, MOUSTGAARD and M ~ ...

The environment is vital to the agricultural sector since it can cause adversities throughout entire productive chain. This study evaluated geographical distribution of zebu breeds in Brazil and correlated their occurrence with environmental variables human development index. Herds purebred cattle (Bos indicus) were classified as beef, dairy, dual-purpose breeds, all spatialized ArcGIS program....

Murrah buffalo and Nellore cattle meat commercialized in Southeastern Brazil were evaluated during aging. Ribeye steaks (Longissimus thoracis muscle) analyzed four wet aging times (0, 7, 14, 21 days) stored at 2 ± 1 °C. The water holding capacity (WHC) decreased (p < 0.05) (0.41 to 0.28), with having lower pH a higher WHC than beef. Lower myofibrillar fragmentation index shear force (WBsSF) ...
