Melanocortin 1 receptor (MC1R) plays a vital role in melanogenesis and determines coat color of mammals. Polymorphic variants in MC1R, causing coat color variation, were described in few mammals; however, such studies were not done in cattle.

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.

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 ...

The global warming driven climate change has increased the susceptibility of livestock around the globe to heat stress (HS), which reduces animal productivity and threatens the sustainability of marginal farmers. The objective of this investigation was to evaluate thermo-adaptability between Tharparkar calves (TC), an indigenous milch breed of India ...

Pharmacokinetics of ivermectin in zebu Gobra (Bos indicus)
Veterinary Parasitology, 2005Plasma 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-

Heterosis in Bos taurus × Bos indicus crosses
Livestock Production Science, 1985Abstract 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 ...

Differences of skin morphology in Bos indicus, Bos taurus, and their crossbreds
International Journal of Biometeorology, 2013Cutaneous 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.

Serological evidence for brucellosis in Bos indicus in Nigeria
Tropical Animal Health and Production, 2011Nigeria 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.
