Kansas Agricultural Experiment Station Research Reports

One-hundred twenty crossbred barrows initially weighing 68.7 lb were used to determine the lysine requirement of growing pigs injected with 5 mg/d porcine somatotropin (PST) during a 5-wk growth trial. Pigs received one of six levels of dietary lysine (.7, 1.1, 1.5, 1.9,2.3, or 2.7%) and were injected daily with either 5 mg pST or placebo. During the 5 wk trial, pST-injected pigs had increased average daily gain (ADG), decreased average daily feed intake (ADFI), and improved feed conversion (F/G) compared with placebo-injected pigs. With increasing dietary lysine, ADFI of pigs injected with both pST and placebo was reduced. Pigs …

Eighty crossbred barrows initially weighing 70.5 lb were used in a 5 wk trial to determine the optimum dosage of porcine somatotropin (PST) required to promote maximum growth response in growing pigs fed diets containing either 1.0 or 2.0% lysine. Pigs received a daily injection of placebo or 2, 4, or 8 mg pST in combination with one of two experimental diets containing either 1.0 or 2.0% dietary lysine. Increasing the dosage of pST of pigs fed both diets resulted in an increase in average daily gain (ADG), a reduction in average daily feed intake (ADFI), and an improvement in …

Kansas Agricultural Experiment Station Research Reports

Six cannulated barrows and two hundred eighty-eight chicks were used in an experiment to determine the value of an in vitro protein digestibility assay (pepsin digest) for identification of sorghum parent lines with improved nutritional value. The barrows were used to determine digestibility of the experimental sorghums at the terminal ileum and for the total digestive tract. Due to a limited supply of the sorghums, broiler chicks were used as a model to predict the value of the experimental sorghums for growth performance. Four sorghum parent lines were selected from 100 SI families grown at several locations in Kansas. Two …

Kansas Agricultural Experiment Station Research Reports

Forty-eight weanling pigs (6.9 lb initial wt) were used in a 28-d growth study to determine the feeding value of expelled soybean meal (43% CP) as compared to conventionally extracted soybean meal (48.5% CP). Pigs were fed one of two dietary treatments containing either expelled soybean meal or conventional soybean meal. Both diets contained milo and 10% dried whey and were formulated to be slightly lysine deficient (.95%) to determine any potential differences in amino acid availabilities between the two soybean meals. From d 0 to 14, pigs fed conventional soybean meal had higher average daily gain (ADG) and average …

Ksu Swine Enterprise Record Program (1991), Michael R. Langemeier, Robert D. Goodband, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

On January 1, 1991, a enterprise record program was implemented on 13 swine operations in Kansas. The program evaluates economic criteria in the areas of variable and fixed costs, labor, marketing, and production and is conducted in cooperation with extension specialists and swine producers in Kansas, Nebraska, and South Dakota. Every six months, producers' records are summarized, and the data are pooled to form state and regional averages. This data base is then divided into the top, middle)and bottom third of producers based solely on profit per cwt. of pork produced. This summary allows producers to compare their individual records …

Kansas Agricultural Experiment Station Research Reports

Twenty four pigs were weaned immediately at farrowing, reared artificially for 21 d, and then used in a 35-d nursery experiment to determine the effects of essential fatty acid deficiency on immune function. Treatments were: 1) a semi-purified diet deficient in essential fatty acids and 2) diet 1 with 2% added linoleic acid. Conversion of linoleic acid to linolenic and then arachidonic acid is a normal step in fatty acid metabolism. Metabolites of arachidonic acid are thought to have a role in mediating immune function. On d 28 of the experiment, pigs were orally dosed with Salmonella choleraesuis to challenge …

One-hundred twenty crossbred barrows initially weighing 68.7 lb were used to determine the lysine requirement of growing pigs injected with 5 mg/d porcine somatotropin (PST) during a 5-wk growth trial. Pigs received one of six levels of dietary lysine (.7, 1.1, 1.5, 1.9,2.3, or 2.7%) and were injected daily with either 5 mg pST or placebo. During the 5 wk trial, pST-injected pigs had increased average daily gain (ADG), decreased average daily feed intake (ADFI), and improved feed conversion (F/G) compared with placebo-injected pigs. With increasing dietary lysine, ADFI of pigs injected with both pST and placebo was reduced. Pigs …

Space Requirements Of Finishing Pigs Fed To A Heavier Weight (Removed Individually) (1991), G E. Fitzner, David A. Nichols, Joe D. Hancock, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Space allowances of 6, 8, 10, and 12 ft2 were evaluated for pigs fed from 120 to 250 lb. The management system used was to remove pigs individually as they reached 250 lb, which provided increasing space per pig. Using this management system, average daily gain, average daily feed intake, and feed effeciency improved linearly with increasing space allowance. Pigs allowed 6ft2 gained slower, ate less, and required more feed per lb of gain compared to pigs allowed 8, 10, and 12 ft2. Pigs permitted 8, 10, and 12 ft2 were similar in rate of gain, feed consumption, and feed …

Extrusion Of Sorghum, Soybean Meal, And Whole Soybeans Improves Growth Performance And Nutrient Digestibility In Finishing Pigs (1991), Terry L. Gugle, Robert H. Hines, Joe D. Hancock Jan 1991

Extrusion Of Sorghum, Soybean Meal, And Whole Soybeans Improves Growth Performance And Nutrient Digestibility In Finishing Pigs (1991), Terry L. Gugle, Robert H. Hines, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

One hundred forty-four finishing pigs (124 lb avg initial wt) were used to determine the effects of extruding sorghum, soybean meal (SBM), and whole soybeans on growth performance and nutrient digestibility. Treatments were: 1) control diet with ground sorghum, SBM, and soybean oil; 2) diet 1 with the ground sorghum, SBM, and soybean oil blended and extruded; 3) sorghum and whole soybeans extruded separately and blended; and 4) sorghum and extruded soybeans blended and extruded together. Extrusion was in an Insta-Pro® extruder. All diets were formulated to be equal in concentrations of metabolizable energy (ME) and lysine. Pigs fed diets …

As the swine industry matures, profit margins will decrease. Control of the major factors affecting feed cost will drive the system. Upgrading or maintaining health will be a major emphasis, because disease agents and complexes affect growing-finishing performance. Many diseases, such as pneumonia caused by Actinobacillus (llaemophilus) pleuropneumonia and swine dysentery, dramatically affect growing-finishing performance. Diseases decrease average daily feed intake (ADFI) and increase feed per gain ratio (FIG) in many instances. At the same time, they increase input costs via treatments, vaccines, and feed additives. Historically, our control methods may have been successful on individual farms, but not across …
