Kansas Agricultural Experiment Station Research Reports

We evaluated the effects of a modified-live virus vaccine for PRRS virus on nursery growth performance. The pigs used in this study were obtained from a herd with substandard nursery growth performance attributed to PRRS virus infection. We failed to detect the presence of active circulating field strain virus in either the controls or vaccinated pigs. However, we did detect a strain similar to the vaccine virus strain on d 34 after weaning in the vaccinated pigs. The vaccinated pigs had poorer growth performance from d 7 to 14 after vaccination and were lighter in weight for the remainder of …

This study suggested that experimental potato protein can be an effective replacement for a portion of spray-dried animal plasma in starter diets. Pigs fed combinations of experimental potato protein and spray-dried plasma had greater ADG than those fed either protein source alone. In phase II diets, pigs fed experimental potato protein had similar ADG and FIG compared with those fed spray-dried blood meal and select menhaden fish meal.; Swine Day, Manhattan, KS, November 21, 1996

The Effect Of Carbohydrate Source And Extrusion Processing On Growth Performance On Segregated Early-Weaned Pigs (1996), K Hongtrakul, J R. Bergstrom, I H. Kim, W B. Nessmith Jr, Robert D. Goodband, Keith C. Behnke, Michael D. Tokach, Jim L. Nelssen Jan 1996

The Effect Of Carbohydrate Source And Extrusion Processing On Growth Performance On Segregated Early-Weaned Pigs (1996), K Hongtrakul, J R. Bergstrom, I H. Kim, W B. Nessmith Jr, Robert D. Goodband, Keith C. Behnke, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

A 21-day growth trial was conducted to determine the effect of various carbohydrate sources with or without moist extrusion processing on growth performance of segregated early-weaned pigs. Treatments included five different carbohydrate sources (corn, corn starch, rice, wheat flour, and grain sorghum) with or without moist extrusion processing in a 2 x 5 factorial arrangement. No interactions were observed among carbohydrate sources and extrusion processing. Growth performance was not improved by extrusion processing. Surprisingly, pigs fed corn had poorer growth performance compared to those fed other carbohydrate sources. These results suggest that corn starch, rice, wheat flour, and grain sorghum …

Effects Of Split-Nursing Management On Growth Performance In Nursing Pigs (1996), T S. Donovan, Steven S. Dritz Jan 1996

Effects Of Split-Nursing Management On Growth Performance In Nursing Pigs (1996), T S. Donovan, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

We evaluated the effects of split nursing the lightest 50% of pigs per litter or the lightest and heaviest 50% of pigs per litter at birth on growth performance until weaning. We did not observe any effects of split nursing on growth performance in pigs from litter sizes<9 at birth. Additionally, we did not observe a difference in mean ADG or pig weight at weaning. However, we did observe a reduction in the variation of ADG between litters. The resulting decrease in variation leads to approximately a 55% (1.3 vs 3.0) reduction in pigs weighing less than 8 lb at weaning. We conclude that the greatest economic benefits are derived from split nursing the lightest 50% of pigs from litter sizes greater than or equal to 9.; Swine Day, Manhattan, KS, November 21, 1996

Kansas Agricultural Experiment Station Research Reports

We used high-health status, weanling pigs to evaluate six different protein sources as replacements for spray-dried animal plasma. Spray-dried blood meal, spray-dried egg, spray-dried wheat gluten, extruded soy protein concentrate, select menhaden fish meal, and soybean meal each replaced 2.5 or 5.0% spray-dried animal plasma. Pigs fed increasing levels of spray-dried blood meal, spray-dried egg, or soybean meal had decreased ADFI; however, increasing levels of select menhaden fish meal, extruded soy protein concentrate, and spray-dried wheat gluten had no influence or increased ADFI. For the high-health pigs used in this trial, select menhaden fish meal, extruded soy protein concentrate, and …

Kansas Agricultural Experiment Station Research Reports

Finishing gilts (initially 163 lb) were fed .58% total lysine (.50% apparent digestible) and total sulfur amino acid (TSAA) concentrations of .26,.285, .31, .335, and .36% (.225 to .325% apparent digestible). These values represent TSAA: lysine ratios of 45, 50, 55, 60, and 65%. Results suggest a linear decrease in ADG and ADFI along with poorer F/G with increasing TSAA levels. However, gilts fed .285% TSAA (50% of lysine) had the best ADG and F/G. No effect was observed on any carcass criteria. Based on the results of this study, the TSAA requirement is not greater than .285% total (.25% …

Removing Vitamin And Trace Mineral Premixes From Finisher Diets (154 To 247 Lb) Did Not Affect Growth Performance, Carcass Characteristics, Or Meat Quality (1996), I H. Kim, J H. Lee, J S. Park, Donald H. Kropf, S L. Johnston, P Sorrell, Robert H. Hines, Joe D. Hancock Jan 1996

Removing Vitamin And Trace Mineral Premixes From Finisher Diets (154 To 247 Lb) Did Not Affect Growth Performance, Carcass Characteristics, Or Meat Quality (1996), I H. Kim, J H. Lee, J S. Park, Donald H. Kropf, S L. Johnston, P Sorrell, Robert H. Hines, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Average daily gain; ADFI; F/G; dressing percentage; tenth rib fat thickness and depth; and color, firmness, and marbling of the longissimus muscle were not influenced by omitting the vitamin and(or) trace mineral premixes from diets during finishing (154 to 247 lb). Thus, omitting vitamin and trace mineral premixes can decrease diet costs without decreasing performance or meat quality of high-lean pigs.; Swine Day, Manhattan, KS, November 21, 1996

Kansas Agricultural Experiment Station Research Reports

Omitting the vitamin and trace mineral premixes and(or) adding 2/3 less supplemental inorganic phosphorus source (from .55% down to .40% total P) to diets during late finishing (191 to 265 lb) had no effect on growth performance, carcass characteristics, or muscle quality in high-lean pigs. Thus, this concept can be used to decrease the cost of feeding terminal-cross pigs to heavy weights, while decreasing excretion of minerals from intensive swine operations.; Swine Day, Manhattan, KS, November 21, 1996

Kansas Agricultural Experiment Station Research Reports

Diets that had been processed using standard, long-term, and expander (high shear) conditioning tended to support greater ADG than an unconditioned meal control diet. Pelleting was necessary to maximize efficiency of growth, but only with standard and long-term conditioning. Indeed, the best efficiencies of gain were for pigs fed the expander processed diets, with no additional benefits from pelleting the expanded mash.; Swine Day, Manhattan, KS, November 21, 1996

Effects Of Spray-Dried Blood Cells In Lactation Diets On Sow And Litter Performance (1996), E Weaver, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

High producing sows were used to evaluate the effect of spray-dried blood cells as a dietary protein source on lactation performance and subsequent reproductive performance. No significant differences were observed between sows fed a corn-soybean cells-based diet or a diet containing 2.5% spray-dried blood cells for lactation performance or subsequent reproductive performance. Therefore, spray-dried blood cells can be used as a partial replacelnent for the protein source in lactation diets.; Swine Day, Manhattan, KS, November 21, 1996

Kansas Agricultural Experiment Station Research Reports

In Exp. 1, increasing dietary lysine from .40% to .70% linearly improved ADG, F/G, 10th rib fat depth, and percentage lean in finishing gilts from 200 to 250 lb. Increasing dietary lysine also tended to improve longissimus muscle area. Results from Exp. 2 indicate no improvement in growth or carcass performance of gilts fed greater than .60% lysine. The combined results of Exp. 1 and 2 indicate that finishing gilts from 200 to 250 lb requires between .60% to .70% (18 to 20 g/d) dietary lysine to maximize both growth performance and carcass characteristics.; Swine Day, Manhattan, KS, November 21, …

Kansas Agricultural Experiment Station Research Reports

Eighty crossbred heifers (549 lb initial body weight) were developed in drylot and limit-fed a forage sorghum silage diet predicted to produce gains of either 1 lb/day for the entire developmental period (EVENGAIN) or .25 lb/day for the first two-thirds of the period followed by 2 lb/day during the last third (LATEGAIN). Treatments began on November 7, 1994 and continued until April 24, 1995 (onset of the breeding season). Actual daily gains over the entire feeding period averaged 1.18 and 1.10 lb/day for EVENGAIN and LATEGAIN heifers, respectively. Age and weight at puberty were not affected by feeding treatment.

Inheritance Of The "Rat-Tail" Syndrome (1996), R.R. Schalles

Kansas Agricultural Experiment Station Research Reports

A form of congenital hypotrichosis, commonly known as rat-tail, is characterized by the colored hair anywhere on the body being short, curly, malformed, and sometimes sparse and an abnormal tail switch. The "rat-tail" syndrome is controlled by interaction between two loci. Cattle that express this syndrome must have at least one gene for black color and be heterozygous at the other locus involved.

In Vitro Estimation Of Ruminal Protein Degradability Of Forages (1996), I.E.O. Abdelgadir, R.C. Cochran, E.S. Vanzant, Evan C. Titgemeyer Jan 1996

In Vitro Estimation Of Ruminal Protein Degradability Of Forages (1996), I.E.O. Abdelgadir, R.C. Cochran, E.S. Vanzant, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Ruminal degradation of alfalfa and prairie hay protein was estimated using a proteolytic enzyme from Streptomyces griseus with or without pretreatment with cellulase or a broad spectrum carbohydrase (driselase). Estimates of the undegradable intake protein (UIP) as a percentage of total protein derived from the protease alone were higher than that measured in the animal (i.e., in vivo). Pretreatment of hay samples with cellulase (48 h incubation) or driselase improved the accuracy of UIP predictions compared with those determined using the protease alone.
