Kansas Agricultural Experiment Station Research Reports

One of two oral iron compounds or an injectable iron (100 mg iron per treatment) were administered to pigs on d 1 and 15 postfarrowing, and they were compared with untreated littermates. There was no significant difference between the pigs receiving the oral iron and the negative controls in serum iron or total iron binding capacity. Pigs that received iron by injection had higher serum iron and packed cell volume and a lower total iron binding capacity compared with pigs given oral iron or untreated controls.; Swine Day, Manhattan, KS, November 19, 1992


A Combination Of Spray-Dided Porcine Plasma And Spray-Dried Blood Meal Optimizes Starter Pig Performance, L J. Kats, J L. Laurin, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband Jan 1992

A Combination Of Spray-Dided Porcine Plasma And Spray-Dried Blood Meal Optimizes Starter Pig Performance, L J. Kats, J L. Laurin, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

A total of 298 weanling pigs (initially 12.11b and 19 d of age) was used in a 25-<1 growth trial to examine the influence of various combinations of spray-dried porcine plasma (SDPP) and spray-dried blood meal (SDBM) in a high nutrient density diet on starter pig performance. Pigs were allotted by weight to eight replicates of five treatments with seven to eight pigs per pen. Pigs were assigned to one of five dietary treatments with 0, 25, 50, 75, or 100% of the SDPP replaced with SDBM on an equal lysine basis. Therefore, diets contained 10, 7.5,5.0, 2.5, or 0% SDPP combined with 0, 1.63, 3.25, 4.8, or 6.5% SDBM, respectively. All phase I diets were formulated to contain 20% dried whey, 1.50% lysine, .81% isoleucine, and .37% methionine. These diets were fed from d 0 to 14 postweaning. On d 14, all pigs were switched to a common phase II diet containing 10% dried whey and 2.5% SDBM and was formulated to 1.25% lysine. Pigs were fed this diet for the remainder of the trial (d 14 to 25 postweaning). A quadratic response occurred for average daily gain and feed efficiency during phase I, with pigs fed a combination of spray-dried porcine plasma and spray-dried blood meal having superior performance compared to pigs fed diets containing only spray-dried plasma or spray-dried blood. Maximum performance was seen with the combination of 7.5% spray-dried porcine plasma and 1.63% spray-dried blood meal. Therefore, the results of this trial show that phase I diet cost can be reduced and performance improved by formulating the diet with a combination of spray-dried porcine plasma and spray-dried blood meal rather than spray-dried plasma alone.; Swine Day, Manhattan, KS, November 19, 1992

Kansas Agricultural Experiment Station Research Reports

Two experiments were conducted to determine the effects of mill type and particle size uniformity on finishing pigs. In Exp. 1, 120 pigs, with an average initial weight of 105 lb, were fed corn-soybean meal-based diets for 57 d. The corn was milled so that all diets had an average mean particle size of 800 11m (± 20), yet differed in particle size uniformity (Sgw). To obtain the most uniform treatment (1.9 Sgw), corn was milled through a roller mill. The intermediate treatment (2.3 Sgw) was obtained by milling corn through a hammermill. The least uniform treatment (2 ...
