Effects Of Lecithin And Lysolecithin On The Digestibility Of Fat Sources In Diets For Weanling Pigs, D B. Jones, Jim L. Nelssen, Robert H. Hines, Joe D. Hancock Jan 1989

Effects Of Lecithin And Lysolecithin On The Digestibility Of Fat Sources In Diets For Weanling Pigs, D B. Jones, Jim L. Nelssen, Robert H. Hines, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Ninety-six pigs (17 d of age and 11.6 lb initial wt) were utilized to determine if adding emulsifiers (lecithin and lysolecithin) to diets containing 10% added fat would affect nutrient digestibility. Fat sources were: 1) soybean oil, 2) tallow, 3) lard, and 4) coconut oil. Lecithin and lysolecithin were added as 10% of the added fat. Pigs were limit fed using the following equation: daily feed allowance = .05 x body wt^9. After a 7-d adjustment period, feces were collected for 4 d, pooled, and analyzed for fat, nitrogen, and energy content. Soybean oil and coconut oil were more ...


Effects Of A Flavoring Agent On Finishing Swine Performance, M E. Johnston, G R. Stoner, Jim L. Nelssen Jan 1989

Effects Of A Flavoring Agent On Finishing Swine Performance, M E. Johnston, G R. Stoner, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

A finishing study was conducted to evaluate the effect of a commercially available flavoring agent on finishing pig performance. One hundred ninety-two finishing pigs were used in the study. Half the pigs received the finishing diet with added flavor, whereas the other half received the same diet without flavor. There were no differences in average daily gain (ADG) between pigs fed either the flavored or non-flavored feed. However, the pigs receiving flavored feed had significantly higher average daily feed intake for the entire trial. Feed efficiency was better for pigs fed the non-flavored diet than for those fed the flavored ...


Dose-Response Of Weanling Pigs To Streptococcus Faecium, B J. Healy, Joe D. Hancock, Daniel Y.C. Fung, C Liang, S L. Yu Jan 1989

Dose-Response Of Weanling Pigs To Streptococcus Faecium, B J. Healy, Joe D. Hancock, Daniel Y.C. Fung, C Liang, S L. Yu

Kansas Agricultural Experiment Station Research Reports

Two 5-wk experiments, using a total of 270 pigs (avg initial wt of 16.1 and 13.11b), were conducted to determine the dose-response relationship between Streptococcus faecium additions to drinking water and performance of newly weaned pigs. In experiment 1, treatments were: 1) untreated control; 2, 3, and 4) .5, 2.5, and 4.5 x 109 CFU of S. faecillm/pig/d; 5) antibioticfed positive control (CSP250 and CUS04)' Bacterial content of feces collected from the pigs on d 7, 14, and 21 indicated that antibiotic feeding greatly reduced fecal content of streptococci. S. faecium given in the ...


Effects Of Daily Porcine Somatotropin Administration On Tile Performance And Carcass Characteristics Of Finishing Swine, G E. Fitzner, David A. Nichols, B R. Schricker, D E. Darden, T L. Weeden, Robert D. Goodband, Robert H. Hines, Jim L. Nelssen, Donald H. Kropf Jan 1989

Effects Of Daily Porcine Somatotropin Administration On Tile Performance And Carcass Characteristics Of Finishing Swine, G E. Fitzner, David A. Nichols, B R. Schricker, D E. Darden, T L. Weeden, Robert D. Goodband, Robert H. Hines, Jim L. Nelssen, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

One hundred forty-four pigs (72 barrows and 72 gilts) were utilized in six treatments with six pens each to evaluate four levels of daily porcine somatotropin (pST) injections (0, 1, 3, or 5 mg/d) in combination with diets containing 13 or 16% crude protein (CP). One randomly selected pig from each pen was slaughtered when it reached a weight between 230 and 240 lb. Daily feed intake (ADFI), tenth rib backfat, and estimated percentage of lean pork were reduced in pigs fed the 13% CP diet and injected with 3 mg/d pST compared to pigs fed the same ...


Effect Of Diet Particle Size On Utilization Of Sunflower Oil Seeds In Nursery Pig Diets, G E. Fitzner, T L. Weeden, Robert H. Hines, Robert D. Goodband Jan 1989

Effect Of Diet Particle Size On Utilization Of Sunflower Oil Seeds In Nursery Pig Diets, G E. Fitzner, T L. Weeden, Robert H. Hines, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

One hundred ninety-two weanling pigs were fed diets containing 15 or 25% sunflower oil seeds that were ground using a hammermill equipped with either a 1/8 or 3/16 in. screen. Average daily gain (ADG) of pigs fed the 25% sunflower seed diet ground through a 1/8 in. screen was similar to ADG of pigs fed the control diet or that with 15% sunflower seeds, although there was a reduction in ADFI. This indicates that finely ground sunflower seeds can be utilized in nursery pig diets up to 25% with no impairment in performance.; Swine Day, Manhattan, KS ...


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

Development Of Methods For Studying Embryo-Uterine Interactions, 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 ...


Effect Of Soybean Processing On Starter Pig Performance And Nutrient Digestibility, D F. Li, R C. Thaler, Jim L. Nelssen, Keith C. Behnke Jan 1989

Effect Of Soybean Processing On Starter Pig Performance And Nutrient Digestibility, D F. Li, R C. Thaler, Jim L. Nelssen, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

One hundred sixty-eight pigs were used to evaluate the effect of soybean processing on starter pig performance and nutrient digestibility. Soybean products tested were commercial soybean meal, full-fat roasted soybeans from either a Roast-A-Tron or Rickles Roaster, extruded soybeans, and steam-flaked soybeans. Pigs fed soybeans from the Rickles Roaster had lower average daily gain, average daily feed intake, and feed efficiency than pigs fed the other soybean products. Rickles soybeans had lower apparent digestibility of nitrogen, dry matter, total fat, and long chain fatty acids than the other treatments. Pigs fed steam-flaked soybeans had the second lowest growth rate. These ...
