The effect of oxfendazole (Synanthic) on weight gain and reproductive performance of spring-born heifer calves was evaluated at five locations (IL, IN, MI, MO, ND). Three hundred thirty-eight mixed-breed beef heifers (293.4 kg) blocked by weight and

Publikováno v: Canadian Journal of Animal Science. 73:287-293

Twenty-six of 52 heifers with an average liveweight of 318 kg were dewormed by intraruminal injection of oxfendazole and placed in drylot on 31 January. The other 26 animals served as controls. All heifers were pastured starting on 14 June and the tr

Adding an Alternative Livestock Enterprise to a Grain Farm

Autor: David L. Watt, R. S. Sell, S. L. Boyles

Publikováno v: Journal of Production Agriculture. 5:422-426

Traditional pastured cow-calf (Bos taurus L.) herds are disappearing from cropable lands. Some cropland farmers may have the ability and facilities to add semiconfinement cow-calf herds to their grain farms. This study demonstrates a technique for de

Feedlot performance of Brahman × Angus versus Angus steers during cold weather

Autor: S L Boyles, J. G. Riley

Publikováno v: Journal of Animal Science. 69:2677-2684

Ten Angus and 10 Brahman x Angus F1 steers were used in a 184-d trial to compare feedlot performance during cold weather (-9 to 26 degrees C). Both groups of steers were exposed to the same environment for the same amount of time. All steers were fed
