Pregnancy rate after ftai in braford heifers submitted to j-synch protocol: Taxa de prenhez na iatf em novilhas braford submetidas ao protocolo j-synch

, 2020
The objective of the present work was to evaluate the effect of J-Synch protocol on pregnancy rate (PR) of heifers artificially inseminated after detected estrus (DEAI) or at fixed-time (FTAI). Two hundred ninety-three Braford heifers were used. On day 0, all animals received 2.0 mg of estradiol benzoate administered intramuscularly (IM) and an ...

Genotype by environment interaction in ultrasound carcass traits and growth of Hereford and Braford cattle

Ciência Rural
ABSTRACT: In beef cattle breeding programs, various selection criteria have been proposed and employed with the aim of improving traits related to carcass composition and the quality of the final product, meat. However, the importance of genotype by environment interaction (G×E) for such traits is still not well understood.
