Teat Necrosis In Newborn Gilts (1978), D A. Schoneweis Jan 1978

Teat Necrosis In Newborn Gilts (1978), D A. Schoneweis

Kansas Agricultural Experiment Station Research Reports

Marked enlargement and edema of the vulva are often noted in newborn gilts. An accompanying, but less conspicuous, lesion is enlarged, engorged mammary glands. Although not fully understood, the changes are thought to result from increased estrogen in sows before they farrow. The edema of the vulva usually causes no lasting problems but enlarged mammary glands are more susceptible to injury from a rough surface like concrete slats. Such injuries may lead to teat necrosis and fibrosis, which makes nipples appear inverted and they are often nonfunctional when the gilts farrow. The incidence of teat necrosis can be reduced by …


Performance Of Pigs Fed Corn, Sorghum, Or Wheat With 0 Or 4% Added Fat (1978), G L. Allee Jan 1978

Performance Of Pigs Fed Corn, Sorghum, Or Wheat With 0 Or 4% Added Fat (1978), G L. Allee

Kansas Agricultural Experiment Station Research Reports

We used 96 crossbred pigs averaging 8.3 kg (19.3 lbs.) to compare performances with sorghum, corn, or wheat with 0 or 4% added fat (tallow). The trial ended when pigs averaged approximately 220 pounds. Grain source (sorghum, corn, or wheat) did not affect average daily gain or feed efficiency of pigs during any ration phase (starter, grower, or finisher). Adding fat (to each grain ration) reduced feed intake and improved feed efficiency during each ration phase. The greatest improvement in feed efficiency from added fat was during the finishing phase.; Swine Day, Manhattan, KS, November 9, 1978


Factors Influencing Sickness At Central Bull Test Station, D.S. O'Banion, K.O. Zoellner, R.R. Schalles Jan 1978

Factors Influencing Sickness At Central Bull Test Station, D.S. O'Banion, K.O. Zoellner, R.R. Schalles

Kansas Agricultural Experiment Station Research Reports

Pre-test management was studied on 351 bulls from 54 herds that were tested at the Kansas Bull Test Station at Beloit, Kansas. Charolais, Hereford, Polled Hereford, and Simmental bulls were sick more days than Angus or Limousin between delivery and start of test. Starting ages and weight correlated significantly with sickness. Bulls sick the least had been vaccinated with BVD, IBR, PI3, Pasturella, Blackleg, malignant edema, and lepto before arriving for test.


Selection For Muscling In Durocs (1978), J D. Wheat, Donald H. Kropf, P Na-Lampang, Robert H. Hines Jan 1978

Selection For Muscling In Durocs (1978), J D. Wheat, Donald H. Kropf, P Na-Lampang, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Select line pigs were compared with those in the control line for growth patterns, production traits, and carcass quality. Heritability and genetic correlations were calculated for certain production and carcass traits after five generations of selection.; Swine Day, Manhattan, KS, November 9, 1978
