Effect Of Limited-Creep Feeding On Performance Of Spring-Born Calves: Results Of 1988 Field Trials (1989), D.D. Simms, Gerry L. Kuhl
Kansas Agricultural Experiment Station Research Reports
Two field trials were conducted to evaluate limited-creep feeding of spring- born calves using pelleted creep rations with either 0.5, 5, or 10% salt. Average daily gain was increased (P<.05) over controls in trial 2 and when both trials were combined. However, intakes were higher than desired and feed conversion much poorer than expected.

Fifteen ruminally and 12 esophageally cannulated steers were randomly assigned to receive low (LP), moderate (MP), and high (HP) crude protein (CP) supplements in a 23-day winter grazing trial designed to evaluate dormant tallgrass forage intake and utilization. Supplemental CP levels were 13, 26, or 39%, respectively. Forage organic matter (OM) intake was greatest (P<.05) for the MP steers. Likewise, fiber (NDF) digestibility and ruminal fill were largest (P<.10) for the MP treatment. Furthermore, the quality of diet selected tended to improve with increasing supplemental protein concentration. Increasing CP concentration in supplements dramatically improves the intake and utilization of dormant forage. In this study, intake and digestibility were optimized with the MP supplement.

Influence Of Rumen Bypass Fat In Cattle Supplements On Forage Utilization (1989), R.B. Hightshoe, R.C. Cochran, L.R. Corah, D.L. Harmon, E.S. Vanzant
Kansas Agricultural Experiment Station Research Reports
Incorporation of rumen bypass fat into a supplement to be fed with low quality forage did not affect total dry matter digestibility or ruminal dry matter fill. Similarly, no difference in digestibility was observed among types (animal vs. plant) or levels (low vs. high) of lipids used in this study. Rumen bypass fat apparently avoids the negative impact on forage utilization seen with conventional fats.

Kansas Agricultural Experiment Station Research Reports
One litter of 12 piglets was used in a completely random design to evaluate the effects of hydrocortisone acetate injections on organ weight and carbohydrase activities. Dams' milk was the only food source available to the piglets. When they were 7 d old, six pigs were injected with hydrocortisone acetate (50 mg/kg BW; 50 mg/ml) and six others were injected with an equal volume of saline (1 ml/kg BW). When the pigs were 14 d old, tissues were collected, weighed, and analyzed for carbohydrase activities. Hydrocortisone acetate injection had no effect on pig daily gain (d 7 to 14), liver …

The Reaction Of Slaughter Hog Cash And Futures Prices To Usda Hogs And Pigs Reports (1989), Ted C. Schroeder, J R. Mintert, John M. Blair
Kansas Agricultural Experiment Station Research Reports
This study examined the reaction of slaughter hog cash and futures prices to USDA Hogs and Pigs reports. Over the 1972-87 period, the nearby live hog futures price had $1/cwt or larger absolute price changes on 48% of the trading days immediately after the Hogs and Pigs report release compared to 6% of the days of the release, suggesting that the reports arc providing important new information to the market. Average price moves in cash and futures markets following the report releases were positive, suggesting that price usually increased the day after the reports. Over the 1972-87 period, the cash …

The Genetics Of Lean Growth (1989), David A. Nichols
Kansas Agricultural Experiment Station Research Reports
In recent years, the pork industry has faced numerous challenges. As consumer resistance to fatter meats has increased, the industry has had two options, 1) argue against popular opinion that fat consumption posed a health risk or 2) strive to reduce the fatness of their products. Since the first option is highly unlikely, the NPPC and commodity leaders have moved rapidly, decisively, and aggressively to promote and reposition pork as a vital, healthful part of the U.S. diet. Pork consumption from 1965 to 1985 was reasonably stable (1965, 45 lb; 1985, 44.2 lb). Demand has been stable to declining in …
The Effect Of Dietary Energy Density On Growth Performance Of Finishing Swine Treated With Porcine Somatotropin (1989), G R. Stoner, B R. Schricker, Jim L. Nelssen, Robert D. Goodband, Robert H. Hines
The Effect Of Dietary Energy Density On Growth Performance Of Finishing Swine Treated With Porcine Somatotropin (1989), G R. Stoner, B R. Schricker, Jim L. Nelssen, Robert D. Goodband, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
A growth study (60 barrows averaging 125.4 lb) was conducted to evaluate the effect of dietary energy density on growth performance of finishing pigs treated with porcine somatotropin (pST). Barrows were blocked on weight and allotted randomly to pens (2 barrows/pen, 5 pens/treatment). Barrows were injected daily with 4 mg pST and fed six experimental diets with four energy densities (1.37, 1.48, 1.60, or 1.71 Meal ME/lb) and four lysinc:energy ratios (4.0, 3.7, 3.4, or 3.2 g lysine/Mcal ME). Diets were formulated to contain at least 200% of NRC (1988) recommendations for essential nutrients. Increasing dietary energy density and adjusting …

Kansas Agricultural Experiment Station Research Reports
Space allowances of 6, 8, 10, and 12 ft^2 were evaluated for pigs fed from 130 lb to a pen average of 250 lb. Average daily gain and average daily feed intake. increased linearly (P<.05) as space allowance increased. However, those pigs permitted 10 or 12 ft^2 of space were similar in avg daily gain, avg daily feed intake, and feed efficiency, suggesting that 10 ft^2 of space is adequate for feeding finishing hogs to a heavier average pen weight. Coefficients of variation (CV) for initial weight and final weight were increased for pigs with 6 ft^2, whereas for those exposed to 10 and 12 ft^2, the CV was reduced, indicating more uniform pigs at final weight with greater space allowance.; Swine Day, Manhattan, KS, November 16, 1989
Nutritional Considerations For Improved Lean Value (1989), Jim L. Nelssen
Nutritional Considerations For Improved Lean Value (1989), Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
The swine industry is in a transitional period as it gears up to produce the lean meat required by the consumer. In fact, pork processors arc increasing the production of lean products (boneless loins, 95% fat-free hams) because consumers are willing to pay premiums for low-fat products. New methods of measuring the amount of lean pork (fat-a-meter, etc.) are being developed rapidly, in order to allow the packer to offer price differentials for lean compared to fat pigs. Pork producers, in my opinion, will adjust production systems to meet consumer demands for lean pork when monetary differentials are offered by …

Effect Of Diet Particle Size On Utilization Of Sunflower Oil Seeds In Nursery Pig Diets (1989), G E. Fitzner, T L. Weeden, Robert H. Hines, Robert D. Goodband
Kansas Agricultural Experiment Station Research Reports
One hundred ninety-two weanling pigs were fed diets containing 15 or 25% sunflower oil seeds that were ground using a hammermill equipped with either a 1/8 or 3/16 in. screen. Average daily gain (ADG) of pigs fed the 25% sunflower seed diet ground through a 1/8 in. screen was similar to ADG of pigs fed the control diet or that with 15% sunflower seeds, although there was a reduction in ADFI. This indicates that finely ground sunflower seeds can be utilized in nursery pig diets up to 25% with no impairment in performance.; Swine Day, Manhattan, KS, November 16, 1989

Effect Of Soybean Processing On Starter Pig Performance And Nutrient Digestibility (1989), D F. Li, R C. Thaler, Jim L. Nelssen, Keith C. Behnke
Kansas Agricultural Experiment Station Research Reports
One hundred sixty-eight pigs were used to evaluate the effect of soybean processing on starter pig performance and nutrient digestibility. Soybean products tested were commercial soybean meal, full-fat roasted soybeans from either a Roast-A-Tron or Rickles Roaster, extruded soybeans, and steam-flaked soybeans. Pigs fed soybeans from the Rickles Roaster had lower average daily gain, average daily feed intake, and feed efficiency than pigs fed the other soybean products. Rickles soybeans had lower apparent digestibility of nitrogen, dry matter, total fat, and long chain fatty acids than the other treatments. Pigs fed steam-flaked soybeans had the second lowest growth rate. These …

Kansas Agricultural Experiment Station Research Reports
Limit-feeding a high protein creep (36% CP) and a high energy creep (16% CP) was compared with no supplementation in a 61-day preweaning trial. Salt was used to limit daily creep intake to 1.5 to 2.0 lb per head. Calves given the limited energy and protein creep feeds outgained (P<.01) the unsupplemented calves by 0.2 lb and 0.3 lb, respectively. Conversion of creep feed consumed to extra gain was 6.7 and 5.3 for the energy and protein creep-fed calves, respectively (salt included). Trucking shrink of the noncreep-fed calves on the day of weaning and shipping was 4.9 lb and 7.0 lb less (P<.05) than that of the energy and protein creep-fed calves, respectively. Postweaning daily gains of the energy creep-fed calves was higher than those of both the protein creep-fed calves (P=.09) and the noncreep-fed calves (P<.01) by 0.3 lb and 0.5 lb, respectively. The energy creep-fed calves consumed more (P<.05) daily dry matter than the protein creep-fed and unsupplemented calves. Little difference was observed in postweaning feed conversion among creep treatments.

A Comparison Of Flavor And Tenderness Between Dry-Aged And Vacuum-Aged Beef Strip Loins (1989), K. Warren, Curtis L. Kastner
Kansas Agricultural Experiment Station Research Reports
Starting 3 days postmortem, sections from eight USDA Choice or better, yield grade 4, strip loins were dry-aged (aged unpackaged) or vacuum-aged (aged in vacuum bags) for an additional 11 days. The dry-aged loins lost more (P<.05) weight during aging than vacuum-aged loins, and cooked faster, with less (P<.05) cooking loss than the unaged loins. Vacuum-and dry-aged samples were similar (P>.05) in tenderness, and both were more tender (P<.05) than unaged counterparts. A trained taste panel found no differences in subcutaneous fat flavor. However, lean from the vacuum-aged samples had a more intense sour flavor note and more intense bloody/serumy flavor and metallic notes than either of the other treatments. The lean of dry-aged samples was beefier and had more brown/roasted flavor than vacuum-aged or unaged counterparts.

Calves nursing Polled Hereford cows consumed an average of 11.2 lbs of milk per day, with a peak of 15lbs at 50 days post"¢ calving. calves nursing Simmental cows consumed an average of 16.8 lbs of milk per day, with a peak of 20 lbs at 58 days after calving. All increase of 1lb in daily milk consumption produced approximately 20 lbs increase in weaning weight.

Thirty-one Polled Hereford and 29 Simmental cows were individually fed two energy levels for about the last 4 months before calving. Weight, condition score, backfat thickness, and reproduction were evaluated. No differences were found in efficiency of feed utilization between breeds or between energy levels. These cows started the experiment in moderate body condition, and a 10% reduction in dietary energy level during late gestation did not affect their reproductive performance.

Results of four simulated production systems indicated that high levels of milk produced calves that were heavier at weaning, primarily because of an increase in body fat. High levels of milk production, however, were a disadvantage when calves went directly to the feedlot. With slow-growing calves, the fat either had to be depleted postweaning, or the calves had to be slaughtered at less-than-desirable weights in order to maintain desirable carcass fat. High milk intake is more tolerable for calves with fast growth rates, whereas low milk intake is a an economic necessity for calves with slow growth rates. The moderate …

Angular limb deformity, observed in several breeds of cattle, results in a knock-kneed and splay-footed condition in the front legs. This study shows that angular limb deformity is a congenital structural defect, inherited as a simple, autosomal, recessive trait.

Syncro-Mate B® was capable of inducing estrous behavior in ovariectomized cows. Lengthening the norgestomet implant period from 9 to 18 days did not prevent estrus. The ability of Syncro-Mate B to induce estrous behavior in ovariectomized cows helps explain the variable conception rates obtained after using this product in intact cows.

Injecting a GnRH-analog at the time of estrus or at insemination did not generally improve conception rates in heifers inseminated following a synchronized estrus. However, within some herds. a significant positive response was noted.
