Effect Of Dietary Energy Source On Age And Weight At Puberty Of Beef Heifers, G. A. Wilcox, R. J. Pruitt, P. A. Momont, R. H. Pritchard
Effect Of Dietary Energy Source On Age And Weight At Puberty Of Beef Heifers, G. A. Wilcox, R. J. Pruitt, P. A. Momont, R. H. Pritchard
South Dakota Beef Report, 1989
Forty-four Angus and Simmental sired crossbred heifers were fed two diets of differing composition (high forage or high concentrate). Diets were fed to achieve the same average daily gain to evaluate the effect of energy source on age and weight at puberty. Age at puberty, conception rate, pregnancy rate, weight at puberty, glucose and insulin were not significantly different between treatments.
Estrous Synchronization Of Heifers Using Mga And Prostaglandin: Ranch Results, T. B. Goehring
Estrous Synchronization Of Heifers Using Mga And Prostaglandin: Ranch Results, T. B. Goehring
South Dakota Beef Report, 1989
total of 315 yearling heifers were exposed to an estrous synchronization program which consisted of feeding MGA for 14 consecutive days (.5 mg per head per day), followed by a prostaglandin injection 17 days after the last day of MGA feeding. Two hundred forty-seven (78%) of the heifers were detected in heat and artifically inseminated within 5 days after the prostagllandin injection. Response rate ranged from 75 to 84% between ranches and years.

Ec89-263 Nebraska Breeding And Calving Record Book
University of Nebraska-Lincoln Extension: Historical Materials
This Breeding-Calving Record Book will serve as a useful aid in keeping complete and accurate beef performance records. Performance records have long been recognized as a valuable tool in the selection of genetically superior cattle; in addition, performance records are now being used to eliminate much of the "guesswork" from herd management decisions.

Increased costs of production have caused livestock producers to reduce feed costs whenever possible. Low quality crop residues, because of their availability, receive attention and offer considerable potential for reducing feed costs for cattle producers; however, because they are low in digestibility, intake by livestock is reduced. Treatment of low quality crop residues with anhydrous ammonia improves digestibility or total digestible nutrients (TDN) and increases consumption of these forages. The positive effects of ammonia treatment on digestibility and intake of low quality forages make them a viable possibility in feeding programs.
