Effects Of Fat Level And Calorie-Protein Ratio On Performance Of Finishing Pigs (1976), G L. Allee Jan 1976

Effects Of Fat Level And Calorie-Protein Ratio On Performance Of Finishing Pigs (1976), G L. Allee

Kansas Agricultural Experiment Station Research Reports

One hundred twenty finishing pigs averaging 52.9 kg (116 lbs.) initially were used to study effects of fat level and calorie-protein (C:P) ratio on performance and carcass traits of pigs fed a sorghum-soybean meal basal ration. The basal ration contained 13.1% crude protein, 0.55% lysine, 0.68% calcium and 0.59% phosphorus. Fat (tallow) was added to the basal ration at the expense of sorghum at 0, 3, 6, and 9% while maintaining a constant C:P ratio. Also, 9% fat was added to the basal ration without adjusting the C:P ratio. With a constant C:P ratio, daily gain and feed efficiency were …

Preheating Ventilating Air With Solar Energy (1976), C K. Spillman, F V. Robbins, B A. Koch Jan 1976

Preheating Ventilating Air With Solar Energy (1976), C K. Spillman, F V. Robbins, B A. Koch

Kansas Agricultural Experiment Station Research Reports

When animals are confined inside buildings, ventilating air is required to remove moisture and odors. Young animals require relatively warm temperatures and do not produce enough heat to offset that lost through walls and to warm ventilating air. Supplemental heat required by young animals does not need to be high quality, and heating the air a few degrees is adequate for much of the fall, winter, and spring. For example, assume that a 26-sow, farrowing house has a 500 cfm fan. Current recommendations are to run that size fan continuously during the winter. If the ventilating air is heated 30 …

Correlations For Performance Traits Of Growing Boars (1976), P B. Conley Iii, T W. Orwig, Robert H. Hines Jan 1976

Correlations For Performance Traits Of Growing Boars (1976), P B. Conley Iii, T W. Orwig, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Performance records of 275 boars, beginning at 65 and ending at 250 lbs., were analyzed to determine correlations of performance traits. Fastest growing boars were more efficient (r=-.49). In addition, faster gaining boars also tended to have more backfat (r=.20). Backfat thickness and feed efficiency were not related (r=.0l). Average daily gain from 65 to 220 lbs. was highly correlated with average daily gain from 65 to 250 lbs. (r=.92), which suggests that boars need not be tested to heavier weights. The feed/gain ratios during both test periods likewise were highly correlated (r=.82).; Swine Day, Manhattan, KS, November 11, 1976

Relationship Between Body Measurements And Performance Traits In Boars (1976), P B. Conley Iii, T W. Orwig, Robert H. Hines Jan 1976

Relationship Between Body Measurements And Performance Traits In Boars (1976), P B. Conley Iii, T W. Orwig, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Fourteen body measurements were taken on 259 boars at 65 lbs. and again at 250 lbs. determine the relationship of external body dimensions with certain performance traits. Correlations between body measurements and growth tended to be extremely low for most factors. Our results do not support using body measurements as v1sual indicators of growth. This study suggests that performance testing is still the best way to predict a particular animal's genetic potential.; Swine Day, Manhattan, KS, November 11, 1976

High-Moisture Sorghum For Growing-Finishing Swine (1976), M Trotter, G L. Allee Jan 1976

High-Moisture Sorghum For Growing-Finishing Swine (1976), M Trotter, G L. Allee

Kansas Agricultural Experiment Station Research Reports

Eighty-seven crossbred pigs (averaging 95 pounds initially) were used to compare the value of sorghum grain harvested with high-moisture and stored in an oxygen-limiting structure with that harvested with high-moisture and treated with propionic acid (1.2%), and stored in a metal bin, or field dried. Average daily gain, average daily feed intake, and feed/gain ratios in a growth trial and protein and energy digestibilities in a digestion trial, showed that high-moisture sorghum grain and field-dried sorghum have equal feeding values when compared on a dry-matter basis.; Swine Day, Manhattan, KS, November 11, 1976

Femur Or Phalange Bones As Indicators Of Dietary Phosphorus Deficiency (1976), J Hsu, G L. Allee, B A. Koch Jan 1976

Femur Or Phalange Bones As Indicators Of Dietary Phosphorus Deficiency (1976), J Hsu, G L. Allee, B A. Koch

Kansas Agricultural Experiment Station Research Reports

Fifteen crossbred gilts averaging 115 pounds were fed one of three phosphorus levels 70 days (to 219 pounds average) then their femur and phalange bones were compared. Each group of five gilts had received either 0.40%, 0.50% or 0.60% total dietary phosphorus and 0.65% dietary calcium during the 70-day feeding period. The basal sorghum-soybean meal ration contained 0.30% of plant phosphorus. Specific gravity and X-ray or chemical analysis of femurs showed no significant differences among groups, but the breaking strength of femurs from gilts fed 0.6% phosphorus was significantly higher than that from gilts fed 0.4% phosphorus.

Whey-Reconstituted Milo For Finishing Beef Heifers, K. Bolsen, C. Grimes, R. Mickelson Jan 1976

Whey-Reconstituted Milo For Finishing Beef Heifers, K. Bolsen, C. Grimes, R. Mickelson

Kansas Agricultural Experiment Station Research Reports

Three milo treatments were evaluated in finishing rations for heifers: dry-rolled, reconstituted with water, and reconstituted with whey. Reconstituting milo with water or whey did not increase weight gain or efficiency of heifers over that of heifers fed dry-rolled milo. The slowest and least efficient gains were produced by the water-reconstituted milo. Performances were similar for the dry-rolled and whey-reconstituted milo treatments.

Efficacy Of Feeding Finishing-Pigs To Heavier Weights On Two Protein Sequences (1976), B A. Koch, G L. Allee, Robert H. Hines Jan 1976

Efficacy Of Feeding Finishing-Pigs To Heavier Weights On Two Protein Sequences (1976), B A. Koch, G L. Allee, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Eighty-four pigs averaging 75 lbs. were used to evaluate feeding finishing hogs to 230, 260, or 290 lbs. on two protein regimes. Rate of gain declined after the pigs reached 200 lbs. regardless of protein level, which resulted in an increase of approximately 20 to 25 days required for each pen of pigs to average 30 lbs. of gain. Feed costs increased with the increased pounds of feed required per pound of gain for the heavier weights. Pigs fed the lower protein level from 200 lbs. to final weight required more feed per pound of gain, yielded carcasses with slightly …

Dietary Responses To Processed And Non-Processed Peanuts And Grains By Growing-Finishing Pigs (1976), T F. Balogun, B A. Koch Jan 1976

Dietary Responses To Processed And Non-Processed Peanuts And Grains By Growing-Finishing Pigs (1976), T F. Balogun, B A. Koch

Kansas Agricultural Experiment Station Research Reports

Twenty-four crossbred barrows and gilts averaging 92 lbs. were used to evaluate whole shelled peanut as a protein and energy source for pigs. Pigs used whole peanuts and corn less efficiently than ground peanuts and corn. Feed intake and average daily gain were greatly improved when peanuts and corn were fed in ground form. Roasting peanuts for one hour at 120 C improved performance only slightly over raw peanuts. Pigs fed a soybean meal diet had slightly better average daily gain than those fed a lysine-supplemented peanut meal diet.; Swine Day, Manhattan, KS, November 11, 1976

Effects Of Processing Methods On The Nutritional Value Of Sorghum For Weaned Pigs (1976), G L. Allee Jan 1976

Effects Of Processing Methods On The Nutritional Value Of Sorghum For Weaned Pigs (1976), G L. Allee

Kansas Agricultural Experiment Station Research Reports

One hundred twenty-six weaned, crossbred pigs averaging 14 kg (31 lbs.) initially were used to evaluate the effects of various methods of processing sorghum grain. Processing methods evaluated were: pelleting, extruding, micronizing, high-moisture grain stored in an oxygen limiting structure, and high-moisture grain treated with propionic acid. Except for pelleting, only the grain (sorghum) was exposed to the various processing methods. After being processed, the sorghum was ground and incorporated into a 18% sorghum-soybean meal diet. None of the processing methods increased weight gain of weaned pigs over that by pigs fed the control diet (ground sorghum fed as a …

Acid-Treated High-Moisture Sorghum For Swine (1976), G L. Allee, R Nelson Jan 1976

Acid-Treated High-Moisture Sorghum For Swine (1976), G L. Allee, R Nelson

Kansas Agricultural Experiment Station Research Reports

Three trials involving 166 growing pigs (initial weight 20.5 pounds) and 96 finishing pigs (initial weight 108.7 pounds) were conducted to investigate effects of feeding high-moisture, acid-treated sorghum to swine. Sorghum harvested at 23% moisture was treated with 1.2% propionic acid. Method of processing (whole or ground) and method of feeding (complete or free-choice) were also evaluated. Pigs fed high-moisture, acid-treated sorghum in a complete ration gained at the same rate and just as efficiently as pigs fed the dry, complete ration. Feeding of supplement free-choice tended to reduce daily gain but not feed efficiency. Finishing pigs fed whole, high-moisture, …

Trace Mineral Levels During Gestation Of Sows In Confinement-Effects On Immunoglobin Performance And Health Of Neonatal Pigs (1976), D A. Schoneweis, G L. Allee Jan 1976

Trace Mineral Levels During Gestation Of Sows In Confinement-Effects On Immunoglobin Performance And Health Of Neonatal Pigs (1976), D A. Schoneweis, G L. Allee

Kansas Agricultural Experiment Station Research Reports

We compared the effects of two levels of trace minerals fed dams during gestation on the hemoglobin, packed cell volume, performance, and health of 31 litters of neonatal pigs. The dams had been on concrete all of their lives. There were no significant differences in the hemoglobin or packed cell volume in pigs due to trace mineral levels fed the dam during gestation. There were no apparent differences in the incidence of neonatal disease or other problems in any of the pigs. These results indicate no benefit from adding excess trace minerals to the ration of sows during gestation, even …

Effects Of Inbreeding On Postweaning Performance Of Shorthorn Beef Cattle, M.H. Hall, W.H. Smith, R.R. Schalles Jan 1976

Effects Of Inbreeding On Postweaning Performance Of Shorthorn Beef Cattle, M.H. Hall, W.H. Smith, R.R. Schalles

Kansas Agricultural Experiment Station Research Reports

Two inbred lines of Shorthorn beef cattle were established during 1950 to evaluate inbreeding. Analyses of postweaning production data for the first four generations of inbreeding indicate that inbreeding in calves depresses yearling type score, average daily gain, and weight per day of age, but not feed efficiency. The growth depression effects were relatively minor, however. Inbreeding in dams of the calves did not significantly affect any of those traits. Observations to date indicate that mild inbreeding will not cause fitness traits to deteriorate in beef cattle.
