A high intramuscular fat content characterizes Wagyu (WY) cattle breed. Our objective was to compare beef from WY, WY-by-Angus, or Wangus (WN) steers with European, Angus-by-Charolais-Limousine crossbred (ACL), considering metabolic biomarkers pre-slaughtering and nutritional characteristics, including health-related indexes of the lipid fraction. The fattening system olein-rich diets no exercise restriction included 82 steers, 24 29 WN, ACL. slaughter ages weights were (median interquartile...
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...
Abstract We report an outbreak of pharyngeal inflammation in extensive limousine herd, central Spain, associated with a novel genotype (ST63) Pasteurella multocida capsular serogroup B (capB). The affected cattle all ages, reaching herd‐level death rate 17.6% and case fatality 93.3%. Affected animals showed throat inflammation, respiratory distress finally death, without characteristics depression or haemorrhagic septicaemia acute course. Postmortem examination only revealed including oedema...
