Two experiments (Australia and Mexico) tested whether feed intake (FI) and wool production (WP) are affected by pregnancy (PRG), litter size (LZ), or lamb sex (LS) in Merino-type ewes. In Experiment-1, ewes were either not pregnant (NPR; n = 6), or c

Publikováno v: Journal of Applied Aquaculture. 25:206-218

Fish raised in ponds and fed formulated feed also have access to naturally occurring food items. The contribution of these food items to growth of Bidyanus bidyanus was investigated by assigning fish to four treatments: in diet 1, caged fish were fed

To improve growth rates of Cherax spp. raised for human consumption, considerable research has been conducted to establish nutritional requirements for the formulation of a food pellet. The problem with much of this research is that feed requirements

The opportunity exists to utilise our knowledge of major genes that influence the economically important traits in wool sheep. Genes with Mendelian inheritance have been identified for many important traits in wool sheep. Of particular importance are

This study tested two premises. First, that there is a range in water temperature within which to artificially incubate marron eggs and hatchlings, which enables a combination of rapid development, high survival, and the production of large juveniles
