Genetic evaluation of aspects of temperament in Nellore-Angus calves.
The objective of this work was to estimate heritability of each of 5 subjectively measured aspects of temperament of cattle and the genetic correlations of pairs of those traits. From 2003 to 2013, Nellore-Angus F2 and F3 calves (n = 1,816) were evaluated for aspects of temperament at an average 259 d of age, which was approximately 2 mo after weaning. Calves were separated from a group and sub...
متن کاملThe effect of United States versus New Zealand Angus germplasm on characteristics of crossbred calves.
Blood selenium concentration at birth and growth from birth through finishing were analyzed on progeny from two birth years of Angus bulls of United States (US) or New Zealand (NZ) origin. Dams of the calves were Polled Hereford x Angus crossbreds whose sires had been selected divergently from the national sire summary to be superior (+) or inferior (-) for yearling weight EPD (G) and for total...
متن کاملPemphigus vulgaris acantholysis ameliorated by cholinergic agonists.
BACKGROUND Pemphigus vulgaris (PV) is an autoimmune, IgG autoantibody-mediated disease of skin and mucosa leading to progressive blistering and nonhealing erosions. Patients develop autoantibodies to adhesion molecules mediating intercellular adhesion and to keratinocyte cholinergic receptors regulating cell adhesion. OBSERVATIONS To determine whether a cholinergic agonist can abolish PV IgG-...
متن کاملA familial peripheral neuropathy and glomerulopathy in Gelbvieh calves.
Nine Gelbvieh calves originating in four herds and clinically presenting with rear limb ataxia/paresis had histopathologically confirmed peripheral neuropathy and a proliferative glomerulopathy. Degenerative lesions were severe in peripheral nerves, dorsal and ventral spinal nerve roots, and less marked in dorsal fasciculi of the spinal cord. Cell bodies of spinal ganglia were minimally disease...
متن کاملMaternal and reproductive performance of Brahman × Angus, Senepol × Angus, and Tuli × Angus cows in the subtropics
To determine the maternal and reproductive performance of F1 cows in the subtropics, 42 Brahman × Angus, 34 Senepol × Angus, and 50 Tuli × Angus cows were bred to Angus bulls to calve first and subsequently bred to Charolais bulls to calve as 3to 8-yr-olds. Age at first calving did not differ among crossbred cows. Angus-sired calf birth weights were heavier (P < 0.01) from Senepol × Angus than ...
