Estrus And Early Pregnancy In Sows Weaned At Less Than 11 Or More Than 23 Days: Effects Of Vitamin A And Gonadotropin Treatments, S Tonn, P Groothius, B Boese, R Blair, Duane L. Davis

Kansas Agricultural Experiment Station Research Reports

The problem of reduced reproductive performance in sows weaned at 5 to 11 days (early weaned) after farrowing was assessed by comparing estrous and embryonic traits in these sows and others weaned at 23 to 31 days postpartum. The effects of treatment of both groups of sows with PG600 and vitamin A also were studied. PG600 increased the number of sows in estrus regardless of weaning age and reduced the interval from weaning to estrus for early-weaned sows. Both vitamin A and PG600 tended to increase the number of embryos recovered at 11.5 days after the onset of estrus ...

Kansas Agricultural Experiment Station Research Reports

Eighty crossbred gilts (initially 134 lb) were used in a growth assay to evaluate the effects of supplementing finishing pig diets with betaine and (or) choline on growth performance and carcass characteristics. Betaine at 0 or 1000 ppm and choline at 0 or 100 ppm were used in a 2 x 2 factorial arrangement in eight randomized complete blocks. A fifth treatment, 1000 ppm betaine from a liquid, 16 carbon betaine (Lonzaine 16, distributed by Lonza, lnc., Fair Lawn, NJ), was added to further evaluate the efficacy of another form of betaine. Pigs were blocked by weight and ancestry and ...

The Effect Of Lysine And Valine Fed During Lactation On Sow And Litter Lactation Performance, B T. Richert, R G. Campbell, S Kershaw, S A. Blum, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Two hundred two sows (98 parity 1 and 104 parity 2 sows) were used in a 2 x 3 factorial arrangement of treatments to determine the effect of dietary valine and lysine on sow lactation performance. Treatments included two levels of lysine (.8 or 1.2%) and three valine to lysine ratios (80, 100, 120% of lysine). This experiment was conducted at a research farm of a production facility in New South Wales, Australia from January to March, 1994. For all sows, increasing dietary lysine increased litter weaning weight and litter weight gain and reduced sow weight loss. Increasing dietary ...

Kansas Agricultural Experiment Station Research Reports

Two hundred-three large white x Landrace or large white x Chester White x Landrace sows (40 or 41/treatment, avg parity 3.7) were used in a 26 d lactation experiment to determine the valine requirement of high-producing sows. All diets were formulated to .9% lysine with all amino acids other than valine formulated to be at least 110% of their respective ratios relative to lysine. Synthetic valine replaced cornstarch to provide .75, .85, .95, 1.05, and 1.15% dietary valine. Corresponding valine:lysine ratios were 83, 94, 106, 117, and 128% of lysine.

Advantages And Disadvantages Of Hog Marketing Groups, J Mintert, R Tynon, Michael D. Tokach, Michael R. Langemeier, Ted C. Schroeder Jan 1994

Advantages And Disadvantages Of Hog Marketing Groups, J Mintert, R Tynon, Michael D. Tokach, Michael R. Langemeier, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Ten hog marketing groups located in Kansas and Iowa were surveyed during 1993 to determine the success, operation, and management of hog marketing groups. Marketing group leaders were asked to identify principal advantages and disadvantages of marketing hogs in groups. Survey responses indicated that marketing hogs in groups led to producers receiving higher sale prices for their hogs and helped reduce their marketing costs. Commonly cited disadvantages of group marketing, included a loss in marketing flexibility, difficulties in coordinating loads among group members, and concerns about increased susceptibility to diseases from other herds.; Swine Day, Manhattan, KS, November 17, 1994

Kansas Agricultural Experiment Station Research Reports

Ninety-six crossbred pigs (initially 75 lb BW) were used to investigate the effect of increasing dietary carnitine on growth performance and carcass characteristics in growing-finishing swine. Pigs (48 barrows and 48 gilts) were blocked by weight, ancestry, and sex in a randomized complete block design (two pigs per pen and eight pens per treatment). Dietary carnitine replaced cornstarch in the control diet to achieve added dietary carnitine levels of 25, 50, 75, 100, and 125 ppm. Grower (75 to 125 lb) and finisher (125 to 227 lb) diets were formulated to contain 1.0% lysine and .80%, respectively. All diets ...

Kansas Agricultural Experiment Station Research Reports

Four hundred thirty-five pigs (initially 7.7 lb and 10.1 ± 4 d of age) were used to determine the influence of increasing dietary methionine on growth performance of the early-weaned pig (10 d of age). Pigs were blocked by weight in a randomized complete block design, resulting in six to 13 pigs per pen and a total of eight pens per treatment. Experimental diets were fed from d 0 to 21 postweaning. Dietary methionine levels were achieved by adding increasing liquid methionine (Alimet) to a common basal diet. The control diet was corn-based and contained 8.7% moist ...


Injection Of Vitamin A At Insemination And Reproductive Performance In Gilts, D Schoneweis, M Nelson, Duane L. Davis Jan 1994

Injection Of Vitamin A At Insemination And Reproductive Performance In Gilts, D Schoneweis, M Nelson, Duane L. Davis

Kansas Agricultural Experiment Station Research Reports

This experiment tested the hypothesis that an injection of vitamin A on the day of first detected estrus would improve reproductive performance of gilts. Gilts (432) were assigned to either receive vitamin A (1,000,000 IV) or placebo injected intramuscularly on the first day of estrus. No differences in farrowing rate, number of pigs farrowed per litter, or birth weight of pigs were detected. Possibly, gilts do not respond to vitamin A with improved fecundity. Other workers have reported an improvement in litter size for sows. Alternatively, treatment with vitamin A may need to precede estrus to improve litter ...

Comparison Of Lactation Diets Containing Various Protein Sources On Sow And Litter Performance, Steven S. Dritz, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

A total of 188 lactating sows was used in Exp. 1 to determine the influence of a complex lactation diet containing oats, linseed meal, and alfalfa meal compared with a corn-soybean meal diet on sow and litter performance. No differences in sow and litter performance were observed. Therefore, a simple corn-soybean meal diet was adequate 10 maximize sow productivity. Average daily feed intake (ADFI) of sows by parity was also examined in Exp. 1. The ADFI of parity 1 sows was considerably lower than that of parity 3 sows, but litter weaning weights were similar. Thus, lactation diet formulation should ...

Kansas Agricultural Experiment Station Research Reports

Three experiments, using 344 pigs, were conducted to evaluate the influence of β-glucan (MacroGard™-S) on neutrophil and macrophage function, resistance to Streptococcus suis challenge, and growth performance in weanling pigs. β-glucan, when fed at inclusion rates of .05 and .1 %, did not influence neutrophil or macrophage function or increase overall growth performance. Similarly, .025% β-glucan did not alter neutrophil or macrophage bactericidal activity or production of superoxide anion. However, diets containing.025% β-glucan increased average daily gain, average daily feed intake, and pigs weights and decreased plasma haptoglobin levels on d 21. Unfortunately, pigs fed a diet containing .025 ...
