This publication covers how pasture grows, understanding grazing systems, and forage quality. It also covers advanced tools for managing high-intensity grazing systems, such as the feed wedge (also called pasture wedge or grazing wedge).
Many studies have shown that dairies consistently overfeed nutrients such as phosphorus (P) and potassium (K). This practice is expensive and potentially damaging to the environment and to animal health. This publication suggests ways to improve feed management and thus avoid overfeeding P and K. Proper ration balancing is good...

The type of plasminogen activator (PA) secreted by bovine embryos was identified. Day 12 to 14 blastocysts were collected at slaughter from estrous-synchronized, superovulated and naturally mated crossbred beef cows. Embryos were either left as intact embryos (E) or microdissected into component embryonic discs (ED) and trophoblastic vesicles (TV). Intact...

The following experiment presented herein compared growth, physical activity, stress-related responses, and puberty attainment in heifers reared on high- (HIDENS) or low-stocking densities (LOWDENS). Sixty Angus x Hereford heifers were ranked by age and BW (210 ± 2 d and 220 ± 2 kg, respectively) on d 0, and assigned...
To reduce the loss of feeding calves during the nursing period
and to conserve milk for human consumption research has been conducted
to develop milk replacer formulas which result in calf performance
comparable to that of milk. In the first section of this investigation
different aspects of utilization of fats,...
