Effect of early luteolysis in progesterone-based timed AI protocols in Bos indicus, Bos indicus×Bos taurus, and Bos taurus heifers

Theriogenology, 2008
The objective of this study was to evaluate the effects of treatment with an intravaginal progesterone-releasing device (CIDR) and estradiol benzoate (EB) on follicular dynamics in Bos indicus (n=23), Bos taurus (n=25), and cross-bred (n=23) heifers. To assess the influence of reduced serum progesterone concentrations during 8 days of treatment with a ...

Bos indicus (Zebu)

1968
The karyotype of Bos indicus is identical with that of Bos taurus except for the morphology of the Y chromosome. The Y chromosome of B. taurus is a small metacentric, but that of B. indicus is a small acrocentric. Autoradiographs of DNA synthesis during the late S phase invariably show a late replicating small acrocentric.

Differences of skin morphology in Bos indicus, Bos taurus, and their crossbreds

International Journal of Biometeorology, 2013
Cutaneous evaporation is the main avenue by which cattle dissipate heat via the involvement of sweat glands and other skin components. The difference in skin morphology between B. indicus and B. taurus has been recognized, as well as differences in their ability to tolerate heat.

Heterosis in Bos taurus × Bos indicus crosses

Livestock Production Science, 1985
Abstract Data extracted from reports on Bos taurus × Bos indicus crossbreeding were used to estimate the amount of heterosis in these crosses. Traits studied were age at first calving, milk yield, lactation length, and calving interval. The estimates obtained were (percent of midparent means in parentheses): Age at first calving −3.2 to −4.4 ...

Physiological responses of newborn Bos indicus and Bos indicus x Bos taurus calves after exposure to cold.

Journal of Animal Science, 1991
Brahman (n = 9) and 1/2 Simmental x 1/4 Brahman x 1/4 Hereford (n = 11) calves were utilized to determine the influence of exposure to cold on the physiology of the neonate. All calves were removed from their dams within 20 min of birth and prior to suckling.

Logistic regression analysis of pregnancy rate following transfer of Bos indicus embryos into Bos indicus × Bos taurus heifers

Theriogenology, 2007
Factors affecting pregnancy rate of 5627 Zebu embryos in crossbred females with unknown proportions of Holstein and Zebu breeding were examined. After evaluation for developmental stage, quality, and viability, embryos were immediately transferred to recipients.

Pharmacokinetics of ivermectin in zebu Gobra (Bos indicus)

Veterinary Parasitology, 2005
Plasma disposition kinetics of ivermectin was evaluated in a West African cattle breed. Five clinically healthy zebu Gobra cattle (Bos indicus) weighing 220-270 kg were treated (0.2 mg kg-1) with a commercially available ivermectin formulation for cattle. Blood samples were collected by jugular puncture at different times between 0.5 h and 40 days post-

Bos taurus and Bos indicus genome sequencing

2015
The goals of the study and relevance is to explore the phylogenetic relationships and domestication history of Chinese native cattle and other foreign breeds, identify selected genes and genetic variants related to adaptation, domestication, disease-resistance, growth, and meat quality in different cattle breeds.

Serological evidence for brucellosis in Bos indicus in Nigeria

Tropical Animal Health and Production, 2011
Nigeria is the largest cattle-rearing nation in Africa with most animals kept under traditional husbandry practices. While bovine brucellosis does not receive much attention, a relatively high seroprevalence is found in samples submitted for laboratory testing.

Superovulation and embryo transfer in Bos indicus cattle

Theriogenology, 2006
Compared to Bos taurus breeds, Bos indicus breeds of cattle present several differences in reproductive physiology. Follicular diameter at deviation and at the time of ovulatory capability are smaller in B. indicus breeds. Furthermore, B. indicus breeds have a greater sensitivity to gonadotropins, a shorter duration of estrus, and more often express ...
