Evaluation Of Barley For Finishing Swine (1985), Robert D. Goodband, Robert H. Hines Jan 1985

Evaluation Of Barley For Finishing Swine (1985), Robert D. Goodband, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Three-hundred and ten crossbred finishing pigs averaging 110 lbs. were utilized in two growth trials to evaluate the effects of feeding barley to finishing hogs. In both experiments, there were no differences in average daily gain or average daily feed intake between hogs fed the milo-soybean meal control diet, a pelleted barley diet, or a 5% added fat barley diet. However, there was a significant decrease in average daily gain with the basal barley diet and a barley diet balanced on a lysine basis. Pelleting or adding fat significantly improved feed efficiency. In Experiment 2, hogs fed a 5% molasses …

Should You Use Artificial Insemination And/Or Embryo Transfer In Your Swine Operation? (1985), Duane L. Davis Jan 1985

Should You Use Artificial Insemination And/Or Embryo Transfer In Your Swine Operation? (1985), Duane L. Davis

Kansas Agricultural Experiment Station Research Reports

The use of AI and embryo transfer in swine herds will undoubtedly increase during the next decade. The techniques themselves will undergo refinement and improvements as swine producers learn to use them and to manage the genetic aspects of their herds. These techniques should not be viewed as useful tools only for large swine herds. In fact, the relative genetic advantage is probably greater for the medium-sized or small herd, since the superiority of the AI sires compared to boars otherwise available to these herds is relatively greater. Also, access to breeds that are not locally available is an important …

Comparison Of Am-Pm And Dhi Records (1985), James R. Dunham Jan 1985

Comparison Of Am-Pm And Dhi Records (1985), James R. Dunham

Kansas Agricultural Experiment Station Research Reports

A comparison was made of the AM-PM production testing program with the traditional DHI program during 13 test periods of 1984 in the KSU Dairy Teaching and Research Center herd. Although there were slight variations in daily milk weights and percentages of fat and protein in milk, rolling herd averages were nearly identical. Individual 305-2X-M.E. milk and fat records also were compared for 107 cows using both testing programs. Differences between testing programs were minimal) as most records varied by less than 1%. Therefore, it was concluded that the AM-PM program is a very accurate production test.; Dairy Day, 1985, …

Controlling Calving Intervals With Prostaglandin F2Α And Fixed-Time Inseminations (1985), Jeffrey S. Stevenson, M.C. Lucy, Edward P. Call

Kansas Agricultural Experiment Station Research Reports

Prolonged or delayed interval to first breeding is a major cause of long calving intervals. Our objective was to test two methods of artificial insemination by appointment after controlling the onset of estrus for all first breedings after calving. prostaglandin F2α(PGF) was used to time the onset of estrus for cows in two experimental groups. Control cows (inseminated at first heat after 42 days postpartum) had longer intervals to first breeding than the two experimental groups given PCF at 40 to 46 and 51 to 57 days postpartum. Conception rates were lower in the treated cows than in control cows. …

Reproductive Characteristics Of Kansas Holstein Herds Grouped By Rolling Herd Average (1985), Edward P. Call, Jeffrey S. Stevenson Jan 1985

Reproductive Characteristics Of Kansas Holstein Herds Grouped By Rolling Herd Average (1985), Edward P. Call, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

An analysis of 635 Kansas Holstein herds with 41,426 cows indicated that the negative genetic antagonism between production and reproduction can be overcome with good management practices. As rolling herd average increased, only services per conception increased by 0.2 units. All other reproductive traits favored higher yearly production. Days to first service and cows not yet bred are the main factors responsible for less than ideal reproductive performance in Kansas Holstein herds.; Dairy Day, 1985, Kansas State University, Manhattan, KS, 1985;

Rumensin Helps To Reduce The Incidence And Severity Of Legume Bloat In Cattle (1985), Tiruvoor G. Nagaraja, M.P. Katz, L.R. Fina Jan 1985

Rumensin Helps To Reduce The Incidence And Severity Of Legume Bloat In Cattle (1985), Tiruvoor G. Nagaraja, M.P. Katz, L.R. Fina

Kansas Agricultural Experiment Station Research Reports

Monensin at 300 mg and 450 mg per 1000 lbs body weight reduced the severity of alfalfa pasture bloat by 41.2 and 73.1 %, respectively. Lasalocid at the same levels reduced the bloat score by 25.5 and 12.4%. The difference between the two antibiotics appears to be in their ability to inhibit rumen protozoa. Monensin reduced protozoal population in the rumen, whereas lasalocid had no effect. A smaller protozoal population decreases compounds that contribute to frothiness and also increases substances such as plant chloroplasts, which have antifrothing properties.; Dairy Day, 1985, Kansas State University, Manhattan, KS, 1985;

Drought-Stressed, Irrigated, And Additive-Treated Corn Silages For Growing Cattle, K. Bolsen, H. Ilg, R. Smith, J. Hoover, D. Axe Jan 1985

Drought-Stressed, Irrigated, And Additive-Treated Corn Silages For Growing Cattle, K. Bolsen, H. Ilg, R. Smith, J. Hoover, D. Axe

Kansas Agricultural Experiment Station Research Reports

Cattle fed drought-stressed corn silage gained about 10% slower but were just as efficient as cattle fed irrigated corn silage. Because the irrigated corn out yielded the drought corn (17.4 VS. 8.2 tons per acre), the irrigated silage gave a much higher cattle gain per acre (1928 VS. 940 1b). Silo Guard II®-treated silage had an advantage in DM recovery and feed conversion over its control and produced 4.6 more pounds of cattle gain per ton of crop ensiled. Cattle fed H/M Inoculant®- treated silage gained significantly faster than cattle fed the control, however, the treated silage gave only slight …
