Heat stress plays a role in livestock production warm climates. conditions impair animal welfare and compromise the productive reproductive performance of dairy cattle. Under heat conditions, cattle modify their behavior. Thus, assessment behavior alterations can be an indicator environmental or physiological anomalies. Moreover, precision farming allows for individual constant monitoring behavior, arising as tool to assess welfare. The purpose this study was evaluate effect on cows using...
ABSTRACT The influence of estrus and double ovulations Holstein heifers on a 5d‐Co‐synch 72 h protocol during summer was explored. Cycling the 5d‐Co‐72 synchronisation were randomised to carry progesterone device (116) from day 0 5 or not (97), them 100 84 underwent fixed‐time artificial insemination (FTAI). Another 70 showed before first GnRH inseminated. Heifers pregnant 34% (33/97) without device, 44.0% (51/116) with 44.3% (31/70) inseminated after estrus. Pregnancy per (P/AI) tended be...
We compared the effects of milk-feeding in 288 Holstein calves (72 per group) which were fed twice (2F) or thrice (3F) daily, with without addition hydrogenated fat-embedded calcium gluconate (G) supplemented starter food and daily diet up to age 9 months, on calves’ metabolism, growth, health, reproductive efficiency first pregnancy. The received 6 L milk replacer (130 g/L) had ad libitum access water textured calf gluconate. Gluconate supplementation promoted a “catch-up” growth their...
