Space Requirements Of Finishing Pigs Fed To An Average Pen Weight Of 250 Pounds (1989), R I. Nicholson, G E. Fitzner, David A. Nichols, Joe D. Hancock, Robert H. Hines, Robert D. Goodband, Jim L. Nelssen

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

Nutritional Considerations For Improved Lean Value (1989), Jim L. Nelssen Jan 1989

Nutritional Considerations For Improved Lean Value (1989), Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

The swine industry is in a transitional period as it gears up to produce the lean meat required by the consumer. In fact, pork processors arc increasing the production of lean products (boneless loins, 95% fat-free hams) because consumers are willing to pay premiums for low-fat products. New methods of measuring the amount of lean pork (fat-a-meter, etc.) are being developed rapidly, in order to allow the packer to offer price differentials for lean compared to fat pigs. Pork producers, in my opinion, will adjust production systems to meet consumer demands for lean pork when monetary differentials are offered by …

Application Of Technology For Maximizing Lean Growth (1989), Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

The swine industry is at a crossroads that either mayor may not change the way we produce pork in the future. As we head into the 90's, we are entering a new era in terms of growth promotion and carcass modification,which will produce overnight what would have taken generations to select for. Of the compounds tested, porcine somatotropin (pST) has the most potential to alter the structure of the swine industry. Many fear the application of this technology because of potential increases in pork production displacing and leading to fewer producers. Because pork quality will be improved tremendously (50% reduction …

Development Of Methods For Studying Embryo-Uterine Interactions (1989), Z Zhang, Duane L. Davis Jan 1989

Development Of Methods For Studying Embryo-Uterine Interactions (1989), Z Zhang, Duane L. Davis

Kansas Agricultural Experiment Station Research Reports

The endometrium (lining of the uterus) functions to support and nurture developing embryos. However, 20 to 30% of pig embryos are lost in early pregnancy. Therefore, we developed methods to study the endometrium. Our initial work addresses the production of prostaglandins by the endometrium. Prostaglandins are known to play important roles in the establishment of pregnancy. In the pig, this process occurs near the end of the second week of pregnancy. Therefore, we determined the prostaglandin production by glandular and stromal cells of pig endometrium collected on d 13 of pregnancy. Glandular cells produced more prostaglandin F2α (PGF2α) than prostaglandin …

Influence Of Limited-Creep Feeding On Pre- And Postweaning Performance Of Spring-Born Calves, C.E. Binns, F.K. Brazle, Gerry L. Kuhl, D.D. Simms, K.O. Zoellner, L.R. Corah

Kansas Agricultural Experiment Station Research Reports

Limit-feeding a high protein creep (36% CP) and a high energy creep (16% CP) was compared with no supplementation in a 61-day preweaning trial. Salt was used to limit daily creep intake to 1.5 to 2.0 lb per head. Calves given the limited energy and protein creep feeds outgained (P<.01) the unsupplemented calves by 0.2 lb and 0.3 lb, respectively. Conversion of creep feed consumed to extra gain was 6.7 and 5.3 for the energy and protein creep-fed calves, respectively (salt included). Trucking shrink of the noncreep-fed calves on the day of weaning and shipping was 4.9 lb and 7.0 lb less (P<.05) than that of the energy and protein creep-fed calves, respectively. Postweaning daily gains of the energy creep-fed calves was higher than those of both the protein creep-fed calves (P=.09) and the noncreep-fed calves (P<.01) by 0.3 lb and 0.5 lb, respectively. The energy creep-fed calves consumed more (P<.05) daily dry matter than the protein creep-fed and unsupplemented calves. Little difference was observed in postweaning feed conversion among creep treatments.

Effects Of Winter Herbage Removal On Flint Hills Rangeland, Lisa M. Auen, Clenton E. Owensby Jan 1989

Effects Of Winter Herbage Removal On Flint Hills Rangeland, Lisa M. Auen, Clenton E. Owensby

Kansas Agricultural Experiment Station Research Reports

Intensive-early stocking (lES) in the Kansas Flint Hills has greatly increased livestock production efficiency. The potential for grazing of regrowth on IES pastures the following winter was studied by mowing different plots on a monthly basis from October to April, 19831985. Winter herbage removal had no significant effect on herbage production in the following seasons or on the total nonstructural carbohydrates (TNC) of big bluestem (Andropogon gerardii) rhizomes. Since there was no reduction in herbage yield for any mowing date, cattle producers can apparently restock IES pastures after October 1.

Influence Of Supplemental Protein Concentration On Intake, Utilization, And Quality Of Diet Selected By Steers Grazing Dormant Tallgrass-Prairie, T. Delcurto, R.C. Cochran, L.R. Corah, A.A. Beharka, E.S. Vanzant Jan 1989

Influence Of Supplemental Protein Concentration On Intake, Utilization, And Quality Of Diet Selected By Steers Grazing Dormant Tallgrass-Prairie, T. Delcurto, R.C. Cochran, L.R. Corah, A.A. Beharka, E.S. Vanzant

Kansas Agricultural Experiment Station Research Reports

Fifteen ruminally and 12 esophageally cannulated steers were randomly assigned to receive low (LP), moderate (MP), and high (HP) crude protein (CP) supplements in a 23-day winter grazing trial designed to evaluate dormant tallgrass forage intake and utilization. Supplemental CP levels were 13, 26, or 39%, respectively. Forage organic matter (OM) intake was greatest (P<.05) for the MP steers. Likewise, fiber (NDF) digestibility and ruminal fill were largest (P<.10) for the MP treatment. Furthermore, the quality of diet selected tended to improve with increasing supplemental protein concentration. Increasing CP concentration in supplements dramatically improves the intake and utilization of dormant forage. In this study, intake and digestibility were optimized with the MP supplement.

Influence Of Rumen Bypass Fat In Cattle Supplements On Forage Utilization, R.B. Hightshoe, R.C. Cochran, L.R. Corah, D.L. Harmon, E.S. Vanzant Jan 1989

Influence Of Rumen Bypass Fat In Cattle Supplements On Forage Utilization, R.B. Hightshoe, R.C. Cochran, L.R. Corah, D.L. Harmon, E.S. Vanzant

Kansas Agricultural Experiment Station Research Reports

Incorporation of rumen bypass fat into a supplement to be fed with low quality forage did not affect total dry matter digestibility or ruminal dry matter fill. Similarly, no difference in digestibility was observed among types (animal vs. plant) or levels (low vs. high) of lipids used in this study. Rumen bypass fat apparently avoids the negative impact on forage utilization seen with conventional fats.
