Effect Of Select Menhaden Fish Meal And Dried Whey In Starter Diets For Pigs (1987), G R. Stoner, G L. Allee, Jim L. Nelssen, M E. Johnston
Kansas Agricultural Experiment Station Research Reports
A growth trial was conducted to examine the effects of select menhaden fish meal (SMFM) and dried whey (DW) in starter diets for pigs. A total of 240, 3-wk-old, weaned pigs averaging 12.1 lb were utilized. Pigs did not receive creep feed and were introduced to the experimental diets immediately upon weaning. The trial was conducted for 4 wk. A factorial design with 3 levels of SMFM (0, 4, and 8%) and 2 levels of OW (10 and 20%) was employed. Analysis of the data indicated no SMFM x DW interaction by the end of wk 4. Inclusion of SMFM …

Effect Of Fat Source On Performance Of Weaned Pigs (1987), W H. Turlington, G L. Allee, Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
A 5-week trial was conducted to compare various fat sources for the weaned pig. A total of 150 pigs were weaned at 19 days of age and allotted, by weight, to five dietary treatments. Treatments consisted of a control with no added fat and four fat sources (choice white grease, coconut oil, soybean oil and tallow). During the first 2 weeks, 10% fat was added, and 5% fat was added during the last 3 weeks. Average daily gain and feed/gain of weaned pigs were improved with the addition of dietary fat. During the first 2 weeks, pigs fed soybean oil …

One hundred and eighty 3-wk old pigs (initial weight 10.6 lb) were utilized in a 35-day growth trial to determine the effects of the carbohydrate and/or protein fractions of dried whey on pig performance. In addition, 30 3-wk-old pigs (initial weight 10.8 lb) were used in two digestion trials to study the effects of the whey fractions on nutrient digestibility. Dietary treatments included a corn-soybean meal control (CON), control + 20% dried whey (WHE), control + 14% lactose (CHO), control + 2.1% lactalbumin (PRO), control + 14% lactose + 2.1% lactalbumin (CHO + PHD), and control + 8.4% whey protein …
Using Biotechnology To Improve Growth Rate And Carcass Composition In Swine (1987), Jim L. Nelssen
Using Biotechnology To Improve Growth Rate And Carcass Composition In Swine (1987), Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
Biotechnology has developed a number of compounds that partition nutrients away from fat tissue deposition and towards lean (muscle) tissue accretion in swine. Two compounds that have received considerable research attention are porcine somatotropin (growth hormone) and beta agonists. Somatotropin is a naturally occurring protein found in the blood of all mammals. Beta agonists are compounds commonly used in human medicine. Somatotropin and beta agonists can dramatically influence carcass leanness and ultimately pork product quality. Research has shown that porcine somatotropin can increase daily gains up to 19%, improve feed efficiency up to 28%, and reduce backfat thickness up to …
Effects Of Flushing, Altrenogest, And Pubertal Status On Litter Traits In Gilts (1987), M T. Rhodes, Duane L. Davis, Jeffrey S. Stevenson
Effects Of Flushing, Altrenogest, And Pubertal Status On Litter Traits In Gilts (1987), M T. Rhodes, Duane L. Davis, Jeffrey S. Stevenson
Kansas Agricultural Experiment Station Research Reports
We tested the effects of flushing (3.4 lb extra ground sorghum grain for at least 10 days before estrus) and estrous synchronization with altrenogest on litter traits in gilts. Altrenogest had no effect on litter size or weight, but flushing increased both traits. The response to flushing occurred entirely among gilts artificially inseminated at the pubertal estrus. Pubertal gilts represented approximately 40% of the gilts in our experiment, and their improvement in litter size was almost two pigs. When all gilts were considered, flushing improved litter size by .9 pigs.; Swine Day, Manhattan, KS, November 19, 1987

Protein Requirement Of Finishing Barrows And Gilts (110 To 230 Lbs) (1987), Robert H. Hines, B A. Koch, David A. Nichols, L M. Turlington, Robert D. Goodband
Protein Requirement Of Finishing Barrows And Gilts (110 To 230 Lbs) (1987), Robert H. Hines, B A. Koch, David A. Nichols, L M. Turlington, Robert D. Goodband
Kansas Agricultural Experiment Station Research Reports
Eighty barrows and 80 gilts were fed diets containing four crude protein levels (16, 15, 14, and 13%) from approximately 115 lb to a market weight of 230-235 lb. Barrows and gilts were fed separately to determine their protein requirements during the finishing period. Performance traits (ADG, ADF, and F/G) of barrows and gilts were not significantly affected by increasing the protein content of the diet from 13 to 16%. However, barrows linearly decreased in fat thickness at the 10th rib as crude protein content in the diet was increased. Also, percent muscle increased linearly with increased protein for barrows, …
Minimizing Environmental Effects On Nutritional Needs Of Growing Finishing Pigs (1987), David A. Nichols
Minimizing Environmental Effects On Nutritional Needs Of Growing Finishing Pigs (1987), David A. Nichols
Kansas Agricultural Experiment Station Research Reports
Swine have a great ability to grow and reproduce in a variety of environments and facilities. This ability is documented by profitable production in both the most elaborate and the most simple facilities. Efficiency and profitability in environmental extremes are highly variable but performance level during environmental stress is generally less than maximum. The thermal environment strongly influences pig performance with air temperature having the primary effect. All too often, producers fail to consider the total environment of the pig. Air movement, humidity, and, in some instances, solar radiation contribute to how the pig feels. We must consider the total …
The Effect Of Season On Response Of Growing-Finishing Pigs To Dietary Fat Levels (1987), G L. Allee, G R. Stoner, M E. Johnston, Jim L. Nelssen
The Effect Of Season On Response Of Growing-Finishing Pigs To Dietary Fat Levels (1987), G L. Allee, G R. Stoner, M E. Johnston, Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
This experiment was conducted to examine the influence of season on the response of finishing pigs to practical levels of fat addition. A total of 378 pigs (average initial weight per trial ranging from 83 to 98 pounds) were utilized in four finishing trials conducted during time frames approximating the 4 seasons of the year. Groups of pigs were taken off trial as they reached market weight (230 pounds). There was no season x fat level interaction for any of the criteria measured. Therefore, it is concluded that season has essentially no effect on fat level response. Fat addition influenced …

The Changing Structure Of Red Meat Demand (1987), James Mintert
Kansas Agricultural Experiment Station Research Reports
Testing for a demand change was done using pork and beef demand models estimated over the 1950-1984 period. Results suggest that a structural change has taken place in both beef and pork demand. The beef demand change, however, appears to have been more severe than that noted for pork.; Swine Day, Manhattan, KS, November 19, 1987
Effect Of Various Anthelmintics On Growing-Finishing Swine Reared On Dirt Lots (1987), Robert H. Hines, D A. Schoneweis
Effect Of Various Anthelmintics On Growing-Finishing Swine Reared On Dirt Lots (1987), Robert H. Hines, D A. Schoneweis
Kansas Agricultural Experiment Station Research Reports
Two trials involving 262 pigs were conducted to evaluate five worming programs for growing-finishing pigs fed on dirt lots heavily infected with roundworm (Ascarid) eggs. The control pigs (no anthelmentic) were compared in performance (ADG, F/G) and lung liver lesions at slaughter with pigs that received ivermectin on day 1 or day 28, pyrantel tartrate for the first 28 days, or purge treatments between day 28 to 31 with dichlovos or fenbendazole. All pigs gained at a similar rate regard less of treatment; however, those pigs receiving fenbendozole were 8.4% more efficient and those receiving Ivermectin on day 28 were …
Characteristics Of Aerial Dust In Finishing Buildings (1987), A J. Heber, M Stroik
Characteristics Of Aerial Dust In Finishing Buildings (1987), A J. Heber, M Stroik
Kansas Agricultural Experiment Station Research Reports
Eleven finishing units were surveyed to study the characteristics of aerial dust and factors that influence dust concentrations. Feed dust was the major portion of the total dust mass and can be minimized with feed additives, less feed wastage, enclosed feed delivery, and periodic cleaning. Ventilation was the primary method for dust removal. Naturally ventilated buildings had higher dust concentrations than mechanically ventilated buildings because of lower average airflow rates, especially during cold weather. Swine workers can minimize respiratory symptoms by wearing face masks.; Swine Day, Manhattan, KS, November 19, 1987
Live Sheep Exports : Market Update, E J. O'Loughlin
Live Sheep Exports : Market Update, E J. O'Loughlin
Journal of the Department of Agriculture, Western Australia, Series 4
The live sheep export trade has made an important contribution to the Western Australian sheep industry, with the value of exports peaking at $100 million f.o.b. in 1980-81. In that year Western Australia accounted for 61 per cent of the value of Australian exports of live sheep. In addition, the growth of the live export industry has contribuited to higher prices for other catagories of sheep than would otherwise have been the case.

Degree Of Behavioral Neoteny Differentiates Canid Polymorphs, R Coppinger, J. Glendinning, E. Torop, C. Matthay, M. Sutherland, C. Smith

As with juvenile wolves or coyotes, adult livestock conducting dogs displayed the first-half segment of a functional predatory system of motor patterns and did not express play or social bonding toward sheep; whereas, like wolf or coyote pups, adult livestock protecting dogs displayed sequences of mixed social, submissive, play and investigatory motor patterns and rarely expressed during ontogeny (even when fully adult) predatory behaviors. The most parsimonious explanation of our findings is that behavioral differences in the two types of livestock dogs are a case of selected differential retardation (neoteny) of ancestral motor pattern development.
