  • comparison of whey protein concentrate and spray dried plasma protein in diets for weanling pigs1
    The Professional Animal Scientist, 2007
    Co-Authors: R.o. Gottlob, Jim L. Nelssen, Joel M Derouchey, Michael D Tokach, Robert D Goodband, Steven S. Dritz
    Abstract:

    ABSTRACT Two experiments were conducted to evaluate the effects of whey protein concentrate (WPC) and spray-dried plasma protein (SDPP) on growth performance of weanling pigs. In Exp. 1, 180 weanling pigs (initially 6.3 kg) were fed 1 of 5 experimental diets containing 0, 2.5, or 5.0% WPC or SDPP. Pigs were fed the experimental diets from d 0 to 14 after Weaning, with all pigs fed a common diet from d 14 to 27 after Weaning. Overall (d 0 to 27 after Weaning), increasing SDPP from d 0 to 14 linearly increased ADG (P

  • Comparison of water-based and in-feed antimicrobials for growth performance enhancement of weanling pigs

    Abstract:

    A total of 350 weanling pigs (initially 13.0 lb and 14 ± 3 d of age, PIC) were used to determine the effects of water-based antimicrobial on nursery pig growth performance. Pigs were given one of 5 experimental treatments: negative control (no antibiotics in the feed or water), positive control diet containing NeoTerramycin (140 g/ton Neomycin sulfate, 140 g/ton Oxytetracycline HCl), Neomycin sulfate in the water (24.2 mg of Neomycin sulfate per L), Oxytetracycline in the water (24.2 mg of Oxytetracycline per L), and Neomycin sulfate and Oxytetracycline (Neo/oxy) in the water. Overall (d 0 to 28 after Weaning), pigs provided a water antimicrobial had greater ADG (P

  • Effects of extruded-expelled soybean meal and solvent extracted soybean meal level of growth performance of weanling pigs.

    Abstract:

    Summary A total of 350 weanling pigs (initially 15.7 lb) were used to evaluate the effects of soybean meal source and level on growth performance of early weaned pigs. Dietary treatments included a control diet containing no soybean meal, or diets containing 20% or 40% of either solvent extracted soybean meal (SBM) or extruded-expelled soybean meal (EESOY). The SBM and EESOY were analyzed for trypsin inhibitor (0.7 mg TI/g and 1.8 mg TI/g, respectively) to ensure quality, and actual crude protein values (46.9% and 48.3% as-fed, respectively) were used in diet formulation. From d 0 to 14, increasing EESOY decreased ADG and ADFI (linear, P 0.05) were found between soybean meal sources throughout the trial. The results of this study suggest extrudedexpelled soybean meal processed properly and fed in diets immediately after Weaning did not improve growth performance of nursery pigs relative to conventional solvent extracted soybean meal. When EESOY or SBM was included at 40% in diets fed immediately after Weaning, growth performance of weanling pigs was poorer than if fed at lower levels (20%). Feeding properly processed EESOY resulted in similar growth performance compared to feeding SBM.

  • effects of a whey protein product and spray dried animal plasma on growth performance of weanling pigs
    Journal of Animal Science, 2000
    Co-Authors: G S Grinstead, Steven S. Dritz, Jim L. Nelssen, Michael D Tokach, Robert D Goodband, Jason C Woodworth, M Molitor
    Abstract:

    Five experiments were conducted to evaluate the effects of a high-protein, whey protein product (WPP; 73% CP, 6.8% lysine, 12.8% fat, and 5% lactose) and spray-dried animal plasma (SDAP) on growth performance of weanling pigs. In all experiments, pigs were fed experimental diets from d 0 to 14 after Weaning in a pelleted form and then a common diet in meal form for the remainder of the experiment. Dietary treatments were established by substituting WPP or SDAP for dried skim milk (Exp. 1) or soybean meal (Exp. 2, 3, 4, and 5) in the control diet. In Exp. 1, we maintained a constant level of lactose in all diets by adjusting the amount of added crystalline lactose. The amount of lactose in diets used in Exp. 2 through 5 varied slightly by the addition of WPP. In Exp. 1 and 2, 180 weanling pigs (initially 5.8 kg and 19 +/- 1 d of age or 5.5 kg and 17 +/- 1 d of age, respectively) were used. Treatment diets contained SDAP (2.5 and 5%) or WPP (2.7 and 5.4% in Exp.1, and 2.5 or 5.0% in Exp. 2). In Exp. 1, from d 0 to 7 after Weaning, ADG and ADFI increased with increasing SDAP (linear, P < .01). No other treatment effects were observed during the d 0 to 14 period. In Exp. 2, from d 0 to 14 after Weaning, ADG and G:F increased (linear, P < .04) with increasing SDAP or WWP. In Exp. 3, 305 weanling pigs (initially 4.1 kg and 12 +/- 1 d of age) were used. The control diet contained 2.5% SDAP. The experimental diets were similar to the control diet but contained an additional 2.5 or 5.0% SDAP or 2.5 or 5.0% WPP. From d 0 to 14 after Weaning, ADG, ADFI, and G:F increased (quadratic, P < .05) with increasing SDAP up to 5.0%. Increasing WPP increased ADG (quadratic, P < .07) and ADFI (linear, P < .09). In Exp. 4 and 5, 329 and 756 weanling pigs (initially 4.1 kg and 12 +/- 1 d of age and 5.2 kg and 18 +/- 1 d of age, respectively) were fed diets in which WPP was substituted for 0, 25, 50, 75, and 100% (Exp. 4) or 0, 50, and 100% (Exp. 5) of the SDAP in the control diet. In Exp. 4 and 5, from d 0 to 14 after Weaning, pigs fed a 1:1 blend of each protein source had better ADG (quadratic, P < .04) than those only fed SDAP. In conclusion, WPP can be used in combination with or as a total replacement for SDAP in diets for weanling pigs without reducing performance.

  • Effects of pelleting and pellet conditioning temperatures on weanling pig performance

    Abstract:

    Two studies were conducted to evaluate the effects of pelleting and pellet conditioning temperature of diets containing 5% spraydried animal plasma (SDAP) on weanling pig growth performance. In Exp. 1, conditioning temperatures evaluated were 140, 150, 160, and 170EF. In Exp. 2, pellet conditioning temperatures were 140, 155, 170, 185, and 200EF. The results suggest that pellet conditioning temperatures above 170EF decrease weanling pig performance from d 0 to 7 after Weaning. Pellet conditioning temperature should not exceed 170EF (exit temperature of 180EF) for nursery diets containing 5% SDAP.

    Abstract:

    Five experiments were conducted to evaluate the effects of a high-protein, whey protein product (WPP; 73% CP, 6.8% lysine, 12.8% fat, and 5% lactose) and spray-dried animal plasma (SDAP) on growth performance of weanling pigs. In all experiments, pigs were fed experimental diets from d 0 to 14 after Weaning in a pelleted form and then a common diet in meal form for the remainder of the experiment. Dietary treatments were established by substituting WPP or SDAP for dried skim milk (Exp. 1) or soybean meal (Exp. 2, 3, 4, and 5) in the control diet. In Exp. 1, we maintained a constant level of lactose in all diets by adjusting the amount of added crystalline lactose. The amount of lactose in diets used in Exp. 2 through 5 varied slightly by the addition of WPP. In Exp. 1 and 2, 180 weanling pigs (initially 5.8 kg and 19 +/- 1 d of age or 5.5 kg and 17 +/- 1 d of age, respectively) were used. Treatment diets contained SDAP (2.5 and 5%) or WPP (2.7 and 5.4% in Exp.1, and 2.5 or 5.0% in Exp. 2). In Exp. 1, from d 0 to 7 after Weaning, ADG and ADFI increased with increasing SDAP (linear, P < .01). No other treatment effects were observed during the d 0 to 14 period. In Exp. 2, from d 0 to 14 after Weaning, ADG and G:F increased (linear, P < .04) with increasing SDAP or WWP. In Exp. 3, 305 weanling pigs (initially 4.1 kg and 12 +/- 1 d of age) were used. The control diet contained 2.5% SDAP. The experimental diets were similar to the control diet but contained an additional 2.5 or 5.0% SDAP or 2.5 or 5.0% WPP. From d 0 to 14 after Weaning, ADG, ADFI, and G:F increased (quadratic, P < .05) with increasing SDAP up to 5.0%. Increasing WPP increased ADG (quadratic, P < .07) and ADFI (linear, P < .09). In Exp. 4 and 5, 329 and 756 weanling pigs (initially 4.1 kg and 12 +/- 1 d of age and 5.2 kg and 18 +/- 1 d of age, respectively) were fed diets in which WPP was substituted for 0, 25, 50, 75, and 100% (Exp. 4) or 0, 50, and 100% (Exp. 5) of the SDAP in the control diet. In Exp. 4 and 5, from d 0 to 14 after Weaning, pigs fed a 1:1 blend of each protein source had better ADG (quadratic, P < .04) than those only fed SDAP. In conclusion, WPP can be used in combination with or as a total replacement for SDAP in diets for weanling pigs without reducing performance.
