Computer models were used to simulate the feedlot segment of an integrated beef production system. Five breeds, Angus (A), Charolais (C), Hereford (H), Limousin (L), and Simmental (S), in three mating systems, pure-breeding and two- and three-breed rotational crossbreeding, were evaluated for feedlot and carcass performance. Breed data were taken from the literature. Feeder calves (steers and n...

The objective of this study was to determine the relationship between body weight (BW) and heart girth (HG) in Sardi and Timahdite sheep in order to develop a prediction equation of BW from HG. The data used for this study included 476 records on BW and HG (227 in Sardi and 249 in Timahdite) collected on males and females of different ages in 33 private farms. The BW and the HG averaged 34.8 ± ...

Numerous factors affect the ability or choice of fi shes to breed. For example, studies demonstrate that the appropriate amount of light, temperature, and food must be present before many species will breed. For some species, we are also aware of social factors that affect breeding, such as the size or colour of one’s potential mates. Although studies on mate choice (i.e., choice of one potenti...

Does "familiarity breed contempt" or is "to know you is to love you"? In this research, we explore the role of familiarity in music choice. We show that although consumers say they would prefer to listen to unfamiliar music, in actuality familiarity with music positively predicts preference for songs, play lists, and radio stations. Familiarity with music is at least as good, if not a better, p...
