Sire x herd interactions for weaning weight in beef cattle
Article Abstract:
The influence of sire x herd interactions on weaning weight in beef cattle was analyzed using restricted maximum likelihood (REML) methods. Heritability estimates within herds were far above the range of expected values, suggesting the effect of common environmental factors. After adjusting for environmental factors, half-sib progeny in the same herd were more similar in weaning weights than half-sib progeny in other herds. The potential for predicting breeding value exists, but will only be useful in special cases.

Stocker systems
Article Abstract:
The high expense for nitrogen fertilizer has ushered interest in the use of legumes as fertilizers to improve forage yield. Calves were distributed to different stocker systems and fed with randomly designed forage. The use of legumes for stockpiling with tall fescue would reduce quantity of grazed forage and increase need of stockpiling hay. Stockpiled fescue fertilized with nitrogen improves cattle-grazing performance better than cattle fed fescue hay or silage.

Cow-calf production
Article Abstract:
Five calf crops were produced from cows maintained in appropriate reproductive conditions using an all-forage, three-paddock systems during a six year period. The pregnancy rate was 95% which produced high calf weaning weights regardless of forage species grazed. However, fescue-ladino clover required minimum inputs of harvested feed and maintained excellent stands during six years.
