Effect of an energy supplementation, weaning and oestrous synchronisation on ovarian activity and ovulation in early postpartum primiparous Bos indicus cows raised in the tropics of Costa Rica
(American Society for Microbiology., 2015-09-07)
To evaluate the effect of an energy supplementation, 26 postpartum Bos indicus cows were assigned either to receive an energy diet supplementation (n ≤ 11, SSD) or no supplementation (n ≤ 15, NSSD). Cows in the SSD treatment ...
Behavioral characteristics of Bos indicus cattle after a superovulatory treatment compared to cows synchronized for estrus
(Asian-Australasian Association of Animal Production Societies(AAAP), 2011-10)
The intensity and duration of sexual behavior in Bos indicus was assessed through the continuous observation of sexual receptivity. Two groups of cows were formed: only synchronized (n = 50) and other group further ...
Effect of ruminally protected Methionine on the productive and reproductive performance of grazing Bos indicus heifers raised in the humid tropics of Costa Rica
(Springer Science + Business Media B.V., 2008-03-11)
With the objective of evaluating the effect
of methionine supplementation prior to a breeding
program, thirty one heifers (Bos taurus x Bos indicus)
were used averaging 386 ± 29 days of age and a mean
body weight of ...
Evaluation of early embrionic development after natural mating using ultrasonography in bos indicus cows in the humid tropics of Costa Rica
(Springer, 2008)
Fifty-eight nursing Zebu cows averaging 5922 days postpartum were used to
evaluate the early embryonic development by ultrasound under a natural mating system
(bulls A to F). Three consecutive mating periods of 21 days ...
Ultrasonography as Aid for Early Pregnancy Diagnosis in Zebu Cattle in a Natural Mating Programme
(Taylor and Francis Group, 2006)
To utilise ultrasonography in Zebu cattle to test early pregnancy, multiparous Bos indicus COWS (n=74)
were allocated with 2 mature Brahman bulls, which were replaced with new ones every four weeks. COWS
were bled for ...
