  • * Although daily weight and height gains weren't significantly different between probiotic-supplemented and control calves, the growth rate was better maintained in calves receiving the two-strain probiotic combination up to five months old.
  • * Probiotics positively influenced the gut microbiota by improving bacterial ratios and enhancing several metabolic pathways, suggesting that more frequent probiotic administration in the initial days could yield better results for calf development.

Objective: In tropical, subtropical and arid zones, heat stress is the main cause of productivity reduction in cattle. When climate stressors occur, animals become thermal adapted through differential expression of some genes, including heat shock proteins (HSP) family. The aim of this study was to determine levels of expression of HSP60, HSP70, and HSP90 genes in Simmental cattle raised in tropical environments of Mexico.

SexedULTRA-4M™ is made using an improved method of sex-sorting sperm in a less damaging environment for better retaining sperm integrity throughout the sorting process. The objective of this research was to compare conventional (CONV) and SexedULTRA-4M™ (ULTRA-4M) semen for bovine IVP using four Angus bulls. Matured slaughterhouse oocytes (n = 4000) were divided into the CONV group and the ULTRA-4M group (2000 COCs for each semen type).
