The mountain pine beetle, Dendroctonus ponderosae, is a native species of bark beetle (Coleoptera: Curculionidae) that caused unprecedented damage to the pine forests of British Columbia and other parts of western North America and is currently expanding its range into the boreal forests of...

Coat color in Holstein dairy cattle is primarily controlled by the melanocortin 1 receptor (MC1R) gene, a central determinant of black (eumelanin) vs. red/brown pheomelanin synthesis across animal species. The major MC1R alleles in Holsteins are Dominant Black (MC1RD) and Recessive Red (MC1Re). A...

The relative growth and distribution of bone from 256 bovine carcasses were compared among three breed-types (British, up to 30% Charolais and 30-50% Charolais) and three \"sexes\" (heifers, steers and bulls) over a wide range in carcass weight.

In each of 2 yr, 112 spring-born steers were used to evaluate the effect of calf-fed vs. yearling-fed with and without growth implant and β-adrenergic agonist on production parameters and economic potential. Steers were grouped into: (1) non-implanted feeders harvested at 11–14 mo of age, (2)...

The effects of zeranol were studied in 24 steers and 24 bulls starting at an average weight of 200 kg for a trial period of 183 days. Bulls grew faster than steers (P = 0.07) and zeranol-treated cattle showed higher average daily gain than controls (P < 0.05); there was no significant interaction...

Thirty-two cull cows aged from 1 to 13 yr were allocated to five age groups and fed individually for 82 days, then slaughtered. Half of the cows within each group were implanted with 36 mg of zeranol. Zeranol had no significant effect on average daily gain, feed efficiency or backfat thickness,...

Photoperiod, or day length, generates a highly accurate biological calendar that allows animals to anticipate and adapt to environmental change throughout the year. Photoperiod coordinates both daily and yearly rhythms associated with sleep/wake cycles, behavior, and reproduction, including...

Adipose tissue plays a critical role in energy homeostasis and metabolism. There is sparse understanding of the molecular regulation at the protein level of bovine adipose tissues, especially within different fat depots under different nutritional regimes. The objective of this study was to...
