One-hundred fifty pigs weaned at 14 ± 2 days of age and averaging 9.8 ± 2.8 lb were used to determine the effects of increasing levels of dietary lysine on pig performance. Pigs were fed a pelleted corn-soybean meal diet (1.10% lysine) containing 20% dried skim milk and 14.4 % lactose or diets containing 1.25, 1.40, 1.55, or 1.70% lysine provided by L-lysine HCI. Average daily gain (ADG), feed conversion (F/G), and plasma urea concentrations were determined on day 7, 14, and 21 of the experiment. On day 7, ADG increased linearly ...


Transient Hypersensitivity To Soybean Meal In The Early-Weaned Pig, D F. Li, G Reddy, Frank Blecha, Joe D. Hancock, G Allee, Jim L. Nelssen Jan 1988

Transient Hypersensitivity To Soybean Meal In The Early-Weaned Pig, D F. Li, G Reddy, Frank Blecha, Joe D. Hancock, G Allee, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

An experiment was conducted to determine if baby pigs develop intestinal hypersensitivity to dietary soy protein. Challenging nursery pigs with soybean meal following oral infusion of soybean meal from day 7 to day 14 of age resulted in villus atrophy and lower average daily gain by 28 days of age. At 56 days of age, there were no differences in weight gains between pigs fed soy protein and pigs fed milk protein. Pigs exposed to soybean meal before weaning had increased anti-soybean protein immnoglobulin titers at 4 wk (7.2 vs 4.0) and at 8 wk (7.6 vs ...

Effect Of Dietary Folic Acid Additions On Sow Performance Through Two Parities, R C. Thaler, G L. Allee, Jim L. Nelssen, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

A total of 153 gilts from three breeding groups were fed gestation/lactation diets supplemented with either 0, 1.5, or 6.0 g of folic acid/ton of complete feed for two consecutive parities. Serum folate levels were linearly increased by dietary additions of folic acid throughout gestation and lactation, but serum glucose and urea levels were unaffected by treatment. Stage of life cycle also had an effect on serum folate level. Generally, folate levels decreased from breeding to day 60 of gestation in parity 1 for all treatments, then increased through lactation. In parity 2, folate levels decreased ...


Effect Of Wheat Mill Run On Finishing Pig Performance, C H. Fahrenholz, Keith C. Behnke, David A. Nichols Jan 1988

Effect Of Wheat Mill Run On Finishing Pig Performance, C H. Fahrenholz, Keith C. Behnke, David A. Nichols

Kansas Agricultural Experiment Station Research Reports

Finishing pigs were fed diets containing 0, 15, 30, or 45% wheat mill run (WMR) during cold and hot weather. Results indicate that 15% WMR can be included in finishing swine diets without adversely affecting pig performance. Apparent digestibilities of dry matter, gross energy, and crude fiber were lower (P < .05) for diets containing WMR than for the control. During cold weather incorporating up to 15% WMR in the diet may be economically justified, because there was no difference in cost of gain for pigs receiving the control or 15% WMR diets. During hot weather, cost of gain increased as the level of WMR in the diet increased.; Swine Day, Manhattan, KS, November 17, 1988


Effects Of Raw Soybeans, Roasted Soybeans, And Soybean Oil On Finishing Pig Performance, Robert D. Goodband, Robert H. Hines Jan 1988

Effects Of Raw Soybeans, Roasted Soybeans, And Soybean Oil On Finishing Pig Performance, Robert D. Goodband, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Two trials were conducted to evaluate the effects of raw soybeans, roasted soybeans, and soybean oil on finishing pig performance. In trial 1 pigs were fed a low protein control diet containing 7.5% soybean meal and synthetic lysine. Raw soybeans were added at levels of 8.75, 11.90, 15.05, and 18.20% of the diet. The raw soybean additions replaced the synthetic lysine and part of the milo in the diet and provided lysine levels of .60, .67, .74, and .81% as raw soybean level increased, respectively. Increasing level of raw soybeans had no affect on average ...

Wet Vs. Dry Ad Libitum Feeding Of Growing-Finishing Swine, David A. Nichols, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Two hundred and twenty-four growing-finishing pigs were used to evaluate wet vs. dry ad libitum feeding utilizing the Pride of the Farm Maxima®feeder. Growth rate, average daily feed intake, and feed/gain were the same for those pigs fed with feeders having water nozzles in the trough (wet) or (Finishing, Wet vs. Dry) without the nozzles in the trough of the feeder (dry).; Swine Day, Manhattan, KS, November 17, 1988


Low Investment Farrowing Facilities, James P. Murphy Jan 1988

Low Investment Farrowing Facilities, James P. Murphy

Kansas Agricultural Experiment Station Research Reports

Low investment farrowing facilities can be divided into three categories, depending on the level of investment. At the lowest investment level, an individual farrowing shelter that has no floor is utilized. The shelter can be as simple as two sheets of plywood nailed together to create an A frame. Sometimes, rounded "quonset" shelters also are utilized. Since the weather protection is somewhat limited, these types of shelters are normally used to farrow only in the spring and fall. This is sometimes called the two-litter system. Farrowing is normally done on pastures. The shelters utilize no supplemental heat and have no ...

Litter Traits For Gilts Fed 4 Or 7.4 Lb Feed During The First Ten Days After Breeding, Duane L. Davis, Z Zhang, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

We tested the effects of feeding 4 or 7.4 lb of a complete gestation diet to gilts during days 0 to 2 or 3 to 10 after first detected estrus (day 0) and mating. There was a tendency (P = .11) for the 7.4 lb/day treatment to increase litter size when fed from day 0 to 2 and to decrease (P = .17) litter size when fed from day 3 to 10. Gilts artificially inseminated at puberty farrowed fewer (P < .05) pigs than gilts inseminated at a second or later estrus.; Swine Day, Manhattan, KS, November 17, 1988

Folic Acid Supplementation For Sow Diets, Jim L. Nelssen Jan 1988

Folic Acid Supplementation For Sow Diets, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Folic acid is an essential B-vitamin for swine, and green, leafy plants are an -excellent source of this vitamin. Even though pigs cannot synthesize folic acid, bacteria in their lower gut can, making feces another source of folic acid. Research in the late 1940's and early 1950's indicated that folic acid supplementation to pig diets was not necessary. However, in the last 40 years, the number of sows raised in outside lots with access to leafy plants has decreased. Also, improvements in waste removal systems have decreased the sow's access to fecal material. These changes in management ...

Effect Of Processing On Physical Characteristics, Handling Properties And Utilization Of Wheat Middlings, C H. Fahrenholz, G L. Allee, D Eustace, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Wheat middlings were pelleted and ground through different types of grinders. The resulting products were incorporated into finishing pig diets and a digestion trial was conducted to determine the effect of processing on nutrient utilization. Pelleting and grinding midds prior to use in pelleted finishing diets improved pelleting throughput and efficiency. Results of the digestion study showed there were no detrimental effects on nutrient utilization because of processing. This, along with reduced shipping costs and improved handling characteristics, indicate that pelleting wheat midds at the flour mill would be beneficial to the feed industry and could result in lower feed ...

Comparison Of Wet Versus Dry Feeding For Starter Pigs, R C. Thaler, Jim L. Nelssen Jan 1988

Comparison Of Wet Versus Dry Feeding For Starter Pigs, R C. Thaler, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Two studies utilizing a total of 480 pigs (21 days old) were conducted to compare wet versus dry feeding during a 4 wk starter period. Pigs were fed a pelletized, high nutrient density diet for the first 2 wk and a semi-complex diet (meal form) for the last 2 wk. Aqua® feeders were used in all pens. During the first 2 wk of the study, feeding method had no effect on daily gain or feed intake; however, pigs fed dry diets required less feed per pound of gain than did pigs consuming wet diets (P<.0002). For the overall 4 wk trial, gains and feed intake did not differ between treatments, but pigs fed the wet diets were less efficient than pigs receiving the dry diets. Based on these results, wet feeding is not advantageous to starter pig performance.; Swine Day, Manhattan, KS, November 17, 1988

Sunflower Oil Seeds In Nursery Pig Diets, G E. Fitzner, Robert H. Hines Jan 1988

Sunflower Oil Seeds In Nursery Pig Diets, G E. Fitzner, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Two hundred forty pigs were used to evaluate the use of various amounts (0, 10, 15, 20, 25%) of black sunflower oil seeds in weanling pig diets. After 14 days, no significant differences were found between any of the dietary treatments in feed intake (FI), average daily gain (ADG), or feed efficiency (F/G). At the conclusion of the 5-wk study, no differences were found in FI, ADG, or F/G between those dietary treatments containing 0, 10, and 15% sunflower seeds. However, in those diets containing 20 and 25% sunflower seeds, there were linear (p<.05) reductions in FI and ADG. These results indicate that sunflower seeds, when finely ground using a hammermill with a 1/8 in screen, can be used in diets for weanling pigs up to 15% of the diet with no reduction in performance.; Swine Day, Manhattan, KS, November 17, 1988

Hedging Opportunities For Feeder Pig Finishers, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

This study examined the frequency of profitable, short, hedging opportunities that have been available to feeder pig finishers in recent years. The results indicate that there have been periods offering frequent opportunities to "lock in" a profit by hedging. However, there have not been many extended periods beyond 6 mo offering frequent profitable hedging opportunities, and over several feeding periods, no trading day offered profitable hedging opportunities. Though not always offering a profit, the futures market offered some improved returns relative to the cash market. During a few feeding periods, improved return opportunities were present in excess of 80% of ...

Hog Feeders?, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

During the past 6 yr, extensive research has been conducted at KSU to evaluate feeding systems and various types of wet and dry feeders. Comparisons have been made between timed-feeding and ad libitum feeding systems using dry or wet feeders. Timed-feeding did not improve pig performance (ADG, F/G) when compared with ad libitum dry feeding. Wet feeding in most of the trials resulted in approximately 5% improvement in both average daily gain and feed efficiency. Feeding hogs with an oval or rectangular dry feeder resulted in similar pig performance. A11 feeders were easily adjusted to reduce feed wastage to ...

Factors Affecting Feeder Pig Auction Price Differentials, Ted C. Schroeder, J M. Jones, David A. Nichols

Kansas Agricultural Experiment Station Research Reports

A survey of feeder pig sales was conducted at two Kansas feeder pig auctions during the spring and summer of 1988. Several factors were identified that helped explain a large portion of the short-run price differentials observed in feeder pig prices. Physical characteristics of the feeder pigs and changing market fundamentals during the data collection period accounted for 80 percent of the variability in feeder pig prices. The most significant physical characteristics affecting price included weight lot size health, structural soundness, lumps, ruptures and lot uniformity. There are clear incentives for producers to attempt to sell feeder pigs in healthy ...
