Maximizing Farrowing Rate (1989), D G. Levis
Maximizing Farrowing Rate (1989), D G. Levis
Kansas Agricultural Experiment Station Research Reports
Farrowing rate can be defined as: 1) the number of mated females that farrow within a contemporary group per total number of MATED females for this group or 2) the number of females that farrow within a contemporary group per total number of EXPOSED females for this group. Generally, the first definition is used when hand-mating, whereas the second definition has to be used when pen-mating. Regardless of the definition, farrowing rate can be maximized only by taking total control of the breeding herd. High farrowing rates will result when fertility is high in boars, sows, and gilts; however, excellent …

Kansas Agricultural Experiment Station Research Reports
In recent years, the pork industry has faced numerous challenges. As consumer resistance to fatter meats has increased, the industry has had two options, 1) argue against popular opinion that fat consumption posed a health risk or 2) strive to reduce the fatness of their products. Since the first option is highly unlikely, the NPPC and commodity leaders have moved rapidly, decisively, and aggressively to promote and reposition pork as a vital, healthful part of the U.S. diet. Pork consumption from 1965 to 1985 was reasonably stable (1965, 45 lb; 1985, 44.2 lb). Demand has been stable to declining in …

Kansas Agricultural Experiment Station Research Reports
Space allowances of 6, 8, 10, and 12 ft^2 were evaluated for pigs fed from 130 lb to a pen average of 250 lb. Average daily gain and average daily feed intake. increased linearly (P<.05) as space allowance increased. However, those pigs permitted 10 or 12 ft^2 of space were similar in avg daily gain, avg daily feed intake, and feed efficiency, suggesting that 10 ft^2 of space is adequate for feeding finishing hogs to a heavier average pen weight. Coefficients of variation (CV) for initial weight and final weight were increased for pigs with 6 ft^2, whereas for those exposed to 10 and 12 ft^2, the CV was reduced, indicating more uniform pigs at final weight with greater space allowance.; Swine Day, Manhattan, KS, November 16, 1989

Reproductive Status Of Kansas Dairy Herds (1989), Edward P. Call
Reproductive Status Of Kansas Dairy Herds (1989), Edward P. Call
Kansas Agricultural Experiment Station Research Reports
There has been no appreciable change in the reproduction status of Kansas dairy herds over the last 25 yr. For example, the average calving interval was 398 days in 1965 and 405 days in 1988. Analysis of other measures show similar results. Although the long-stated management goal for a dairy herd has been a calf-a-year or 365-day calving interval, few herds realize this efficiency. On the positive side, the stability of reproductive performance is noteworthy, since genetic antagonism exists between production and reproduction. From 1965 to 1988, average yearly milk production in production-tested herds (DHI) has increased 41%.; Dairy Day, …

Forty Holstein cows in mid-lactation were utilized to evaluate the effects of water oxygenation on milk production, milk composition, and somatic cell count. Cows were fed a total mixed ration consisting of 25% alfalfa, 25% corn silage, and 50% corn-soy concentrate on a dry matter basis. Treatments included a 7-day preliminary period followed by two 28-day periods in which the treatments were reversed. Water consumption, milk production, milk composition, and somatic cell count were not different between treatments. Cows receiving oxygenated water were more docile and easily managed than control cows. Ozone introduced into water forms hydrogen peroxide, nitrous oxide, …

Calves were bottle-fed milk replacers at 10% of weekly adjusted body weight for 8 wk. Treatments were 1) no supplements (control), 2) .16 oz vitamin C, or 3) .16 oz vitamin C plus 125 IU/lb vitamin E. Lymphocytes and neutrophils isolated from day 14 and day 28 blood samples were assayed for neutrophil-mediated S. aureus phagocytosis and antibody-dependent cellular cytotoxicity, and for mitogen induced lymphocyte proliferation. Eye and nasal discharges of calves supplemented with vitamin C and vitamins C plus E were less than those of control calves for wk 1 to 8. Lymphocyte proliferation with the mitogens showed a …

Kansas Agricultural Experiment Station Research Reports
The July 1989 USDA Sire Summary introduced a new system for genetic evaluations in dairy cattle. These evaluations, known as the Animal Model (AM), include several new features that help to increase the accuracy of evaluations compared to the way sire summaries were calculated in the past.; Dairy Day, 1989, Kansas State University, Manhattan, KS, 1989; The 1989 Annual KSU Dairy Day is known as Dairy Day, 1989

We all have heard about the use of BST in lactating dairy cattle during the last 6 to 8 years, but what is BST? Bovine somatotropin is another dairy management tool developed to improve the efficiency and reduce the cost of producing milk. It is the newest in a list of technological advances in the dairy industry, such as genetic improvements, nutrition, health, housing, milking equipment and techniques, embryo transfer, and DHI records. BST is a natural protein produced in the anterior pituitary gland of all cattle. Like other proteins, BST is composed of various amino acids (190-199). BST is …
Involution Of The Uterus Of Dairy Cattle (1989), Edward P. Call
Involution Of The Uterus Of Dairy Cattle (1989), Edward P. Call
Kansas Agricultural Experiment Station Research Reports
The rate of involution of the bovine uterus is remarkable. By 20 days after calving, tissue sloughing and hemorrhaging have ceased, and the size of the uterus has been reduced by more than 80%. By 40 days, the uterus has completely involuted except for isolated pockets of leukocytes. Any reproductive or metabolic disorders around calving will delay involution. A preventive herd health program (PHHP) including a reproductive examination of cows within a month after calving will pay dividends in improved reproductive performance. With a sound PHHP, servicing cows on the first heat after 42 days fresh is recommended.; Dairy Day, …
