Economics, Veterinary Service And Herd Health Programs (1982), Steven C. Henry Jan 1982

Economics, Veterinary Service And Herd Health Programs (1982), Steven C. Henry

Kansas Agricultural Experiment Station Research Reports

Among the many changes in the swine industry during the past two decades, the concept of "Herd Health Programs" came to be. Still a buzz word with poorly defined activities, "Herd Health Programs" are part of our industry. Just listen in the halls during producer or veterinary meetings -- we discuss getting one, already having one, offering one, getting into the business of delivering several of them -- and none of us is quite sure what "one" is and, most of all, what it's worth. There should be no surprise that neither of us, producer or veterinarian, really has the …


Little Things That Mean A Lot In Managing Beef Cattle, D. Pretzer Jan 1982

Little Things That Mean A Lot In Managing Beef Cattle, D. Pretzer

Kansas Agricultural Experiment Station Research Reports

Survival in the beef cattle business for the next year or so will depend on doing little things well, says Don Pretzer, extension farm management specialist at Kansas State. "Doing enough little things right will add up to big differences in profitability. no matter whether you're a cow-calf operator, a backgrounder or a cattle finisher." He offers some interesting ideas for cattle ranchers. The economist says cow herd costs are running around $375 per cow-calf unit per year. This includes $178 for feed, including pasture for 15% replacements. 15% interest on the value of the cow ($450) and $32 a …


Silo-Best And Sila-Ferm Additives For Corn Silage And Drought-Stressed Corn Silage For Yearling Steers, K. Bolsen, H. Ilg Jan 1982

Silo-Best And Sila-Ferm Additives For Corn Silage And Drought-Stressed Corn Silage For Yearling Steers, K. Bolsen, H. Ilg

Kansas Agricultural Experiment Station Research Reports

Normal corn silage, with and without additives, and drought-stressed corn silage were evaluated in a 77-day growing trial using 64 steers. Steers fed drought silage had slowest and least efficient gains. Additive-treated silages were used more efficiently than the control silage. Dry matter recovery from the silos was consistently improved by the enzyme additive but not by the microbial inoculant additive. Steer gain per ton of corn crop ensiled was increased by 7.2 and 4.4 lb for enzyme and inoculant silages, respectively, compared with that for the control silage.


The Effect Of Avoparcin On The Performance Of Grazing Steers, L.R. Corah, W.D. Busby, Jack G. Riley Jan 1982

The Effect Of Avoparcin On The Performance Of Grazing Steers, L.R. Corah, W.D. Busby, Jack G. Riley

Kansas Agricultural Experiment Station Research Reports

One hundred two steers were used to study the effect of Avoparcin on the performance of grazing steers. Four desired dosages -- 0. 200, 400. and 600 mg/head/day -- were compared in a self-fed mineral mix. Feeding Avoparcin at the desired level of 400 mg/head/day increased steer gains By 22%.


Reproduction And Production Of Heifers Implanted With Ralgro Before Weaning, D.D. Simms, F.L. Schwartz, L.R. Corah Jan 1982

Reproduction And Production Of Heifers Implanted With Ralgro Before Weaning, D.D. Simms, F.L. Schwartz, L.R. Corah

Kansas Agricultural Experiment Station Research Reports

Over a 3-year period (1976-1978), heifer calves either were not implanted or were implanted between 2 and 5 months of age. In 1977, the study also included heifers implanted at birth. Implanting at birth increased the percentage of heifers open as yearlings. More implanted heifers tended to be open as 2- to 5-year-olds than control heifers, but the differences were not statistically significant. Implanting of the heifers had no effect on weight gains of their calves.


Effect Of 48-Hour Calf Removal, D.D. Simms, Kenneth G. Odde, L.R. Corah Jan 1982

Effect Of 48-Hour Calf Removal, D.D. Simms, Kenneth G. Odde, L.R. Corah

Kansas Agricultural Experiment Station Research Reports

In three field trials, we removed calves from 187 beef cows for 48 hours at the beginning of the breeding season to determine the effect on the cows' cycling activity, conception rate, and pregnancy rate. When calves were removed, the cows were injected with Lutalyse. Removing calves for 48 hours did not change weight gain or sickness incidence of calves, but neither did it facilitate the cows' rebreeding.
