Kansas Agricultural Experiment Station Research Reports
One hundred-eight gilts with an average initial wt of 129 lb were utilized to determine the effects of porcine somatotropin (pST) and dietary phosphorus on growth performance and bone mineralization and mechanical properties during the finishing phase (129 to 230 lb) and a 35 d post-finishing phase. Gilts were injected daily with placebo (control) or 4 mg pST and fed diets containing .4, .8, or 1.2% P during the finishing phase. Administration of pST improved F/G 18%, increased ADG 8%, and decreased daily feed intake 9%. There was a quadratic response to P, because gilts receiving the .8% P diet …

Two experiments were conducted to evaluate the nutritional value of processed wheat gluten for early-weaned pigs. The first experiment involved 72 weanling pigs with an avg age of 20 d and avg wt of 9.2 lb. Six diets were fed to the pigs in individual metabolism cages. Protein sources were casein, flash-dried wheat gluten, spray-dried wheat gluten, two solubilized wheat glutens, and soybean meal. Response criteria were N digestibility, biological value, and N retention. Casein had greater N digestibility, biological value, and N retention than the other protein sources.

Does Extra Feed After Breeding Affect Litter Size? (1991), Duane L. Davis
Kansas Agricultural Experiment Station Research Reports
Fertility was evaluated in sows fed 4 vs 10 lb/d and gilts fed 4 vs 7.4 Ibid during the first 10 days after breeding. No effects on farrowing rate or litter traits were detected. This confirms results of a previous KSU experiment. Therefore, high feed intake after breeding may not affect fertility traits.; Swine Day, Manhattan, KS, November 21. 1991

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 Iines 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
An on-farm field study utilizing 287 crossbred sows was conducted to investigate the influence of additional dietary lysine during lactation on sow and litter performance. At farrowing, sows were randomly assigned to one of two milo-soybean meal diets containing either .65% (13.5 % CP) or .85% lysine (16.3% CP). Average sow parity was 3.75, and sows on both treatments had a similar number of pigs born alive and similar pig and litter birth weights. All litters were equalized to approximately 9.5 pigs within 24 hours following farrowing, and average lactation length was 21 d. No treatment x parity interactions were …

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 …

Runoff Control From Dirt Lots (1991), Joseph P. Harner, James P. Murphy
Kansas Agricultural Experiment Station Research Reports
A recent water quality survey assessment found nonpoint source pollution problems in a majority of Kansas surface waters - 85% of the monitoring sites were impaired by nutrients, 60% of the sites by bacteria, 55% by suspended solids and/or minerals, and 40% by oxygen-demanding substances. Swine producers have the responsibility to maintain the quality of ground or surface water near their production units. Outdoor dirt lots for confinement of swine are often overlooked as an area needing facilities for water pollution control.; Swine Day, Manhattan, KS, November 21, 1991

Evaluation Of A Rotating Drum Mixer (1991), C R. Stark, C H. Fahrenholz, Keith C. Behnke
Kansas Agricultural Experiment Station Research Reports
A "rotating drum" type mixer was tested to determine if it could produce a uniformly mixed feed. Feed was manufactured in four separate trials, which examined addition sequence, mixing time, mixer capacity, and liquid addition. Uniformly mixed feed was obtained after 8 min, when ingredients were properly sequenced and mixed. Smaller batch sizes decreased the time required to obtain a uniform mixture. The mixer distributed liquid uniformly through the feed and had excellent clean-out capabilities.; Swine Day, Manhattan, KS, November 21, 1991

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 …

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 …

Use Of Agronomic Conditions, Genetics, And Processing To Improve Utilization Of Sorghum Grain (1991), P J. Bramel-Cox, Joe D. Hancock
Kansas Agricultural Experiment Station Research Reports
Sorghum grain is an extremely important crop to both farmers and livestock feeders in the High-Plains states (e.g., from Nebraska to Texas). Kansas leads the nation in sorghum production, and as should be expected, Kansas State University has a long history of research to improve the utilization and marketability of this versatile and hardy crop. This paper is a synopsis of current research at KSU and other universities concerning production and use of sorghum grain for feeding swine. Topics addressed include the relatively small loss in nutritional value (4 to 11 %) as test weight decreases from 55 to 35 …
