Kansas Agricultural Experiment Station Research Reports

A total of 180 barrows (initially 7.4 or 11.9 lb and 9 or 19 d of age) was used in a growth assay to determine the influence of two weaning ages and three diet complexity sequences on growth performance and carcass characteristics. The growth performance of pigs used in this trial was excellent, as shown by the range of average age at 240 lb from 144 to 149.7 d. Growth performance was similar regardless of weaning age. Thus, when health status and environment are similar, pigs weaned at 19 d of age can attain a weight of 240 Ib at …

Estrus And Early Pregnancy In Sows Weaned At Less Than 11 Or More Than 23 Days: Effects Of Vitamin A And Gonadotropin Treatments (1994), S Tonn, P Groothius, B Boese, R Blair, Duane L. Davis

Kansas Agricultural Experiment Station Research Reports

The problem of reduced reproductive performance in sows weaned at 5 to 11 days (early weaned) after farrowing was assessed by comparing estrous and embryonic traits in these sows and others weaned at 23 to 31 days postpartum. The effects of treatment of both groups of sows with PG600 and vitamin A also were studied. PG600 increased the number of sows in estrus regardless of weaning age and reduced the interval from weaning to estrus for early-weaned sows. Both vitamin A and PG600 tended to increase the number of embryos recovered at 11.5 days after the onset of estrus.; Swine …

Strategies For Small Dairy Farmers To Be Profitable And Competitive In The Future (1994), B. Cropp Jan 1994

Strategies For Small Dairy Farmers To Be Profitable And Competitive In The Future (1994), B. Cropp

Kansas Agricultural Experiment Station Research Reports

Profitable dairying will not become any easier in the future. Farm level milk prices will continue to be volatile. The government will not provide additional price or income support to dairies. Long-run milk prices will be either flat or perhaps even trending slightly lower. Average annual milk prices will be in the range of $12.00 to $13.25 per hundredweight. Dairy producers must be able to generate adequate net income at these milk price levels. Smaller dairy operators need to find means of being cost competitive with the larger operators. Without question, smaller producers can be profitable in the decade ahead …

Roughage Levels And Comparison Of Mixed Rations Vs Self-Feeders In Whole Shelled Corn Finishing Programs, C.T. Milton, Robert T. Brandt Jr., S.A. Shuey Jan 1994

Roughage Levels And Comparison Of Mixed Rations Vs Self-Feeders In Whole Shelled Corn Finishing Programs, C.T. Milton, Robert T. Brandt Jr., S.A. Shuey

Kansas Agricultural Experiment Station Research Reports

Two trials were conducted to evaluate roughage levels in whole shelled-corn finishing diets and to compare use of self-feeders to a total mixed ration in a whole corn program. In trial 1, steers were fed whole corn diets alone or with 4 or 8% roughage or a rolled corn diet with 8% roughage. Increasing the roughage level increased dry matter in take, feed required per unit of gain, and carcass weight and finish, and reduced the incidence of liver abscesses. Despite better feed efficiency and lower costs of gain, reducing the dietary roughage level reduced profitability because of lighter slaughter …

Effect Of Morning Vs Evening Feeding Of Limit-Fed Holsteins During Summer Months, Robert T. Brandt Jr., Christopher D. Reinhardt Jan 1994

Effect Of Morning Vs Evening Feeding Of Limit-Fed Holsteins During Summer Months, Robert T. Brandt Jr., Christopher D. Reinhardt

Kansas Agricultural Experiment Station Research Reports

Thirty-eight Holstein steers (avg 339 lb) were grouped into four weight blocks, with two pens per block. Within each block, cattle in one pen were fed at 8:00 a.m. and those in the other at 8:00 p.m. All cattle were limit-fed to achieve a programmed rat e of gain of 2.2 lbs/d using NRC net energy equations. The trial lasted from July 13 through September 6, 1993. With the same quantity of feed, cattle fed in the evening gained 18% faster than cattle fed in the morning (P<.02) resulting in better feed efficiency for the evening-fed cattle (P<.06). Average high temperature for the 56-day period was 88F, average low temperature was 69 ÌŠF, average relative humidity was 73%, and average wind speed was 1.8 mph. Feed tended to be consumed within a 3-hour period, regardless of time of feeding. Because the effective ambient temperature frequently rose above the upper critical temperature for cattle (77 ÌŠF), animals needed to expend energy to dissipate excess heat. These results indicate that cattle limit-fed during the summer may utilize metabolizable energy more efficiently if allowed to ferment the bulk of their feed during the cooler hours of the evening.

The Effect Of Feeding Different Levels Of Aureomycin® In A Mineral Mixture To Stocker Cattle Grazing Native Grass, F.K. Brazle Jan 1994

The Effect Of Feeding Different Levels Of Aureomycin® In A Mineral Mixture To Stocker Cattle Grazing Native Grass, F.K. Brazle

Kansas Agricultural Experiment Station Research Reports

Two hundred and forty-three mixed breed steers were allotted to four treatments with two pastures per treatment. Treatments consisted of a free-choice mineral supplement alone or with Aureomycin® added to provide 150, 300, or 450 mg/hd/day. Gain was similar for all four treatments. The percentage of cattle with eye problems was reduced in pastures where 150 and 450 mg of Aureomycin were consumed daily; however, the incidence in the 300 mg/hd/day group was as high as in the control group.

Implanting Suckling Heifer Calves: Growth And Subsequent Performance, D.D. Simms Jan 1994

Implanting Suckling Heifer Calves: Growth And Subsequent Performance, D.D. Simms

Kansas Agricultural Experiment Station Research Reports

A total of 361, suckling, heifer calves was used over a 2-year period to assess the effects of implanting with either Ralgro® or Synovex-C® on growth and subsequent performance as replacement females. Both implants increased (P<.01 ) weaning weights over that of controls, with the weight increase being retained by yearlings. Pelvic area also was increased at 1 year of age by both implants, with Synovex-C producing larger (P<.01) pelvic areas than Ralgro. However, just prior to calving, body weight and pelvic area were similar among treatments. Uterine scores, cycling activity prior to breeding, percentage exhibiting estrus, and pregnancy percentage were similar for all treatments. Implanting tended to reduce first-service conception rates. Synovex-C implanted heifers calved later (P<.05) than Ralgro-implanted heifers and, consequently, their calves tended to be lighter at weaning. Levels of calving difficulty we r e similar for all treatments. In summary, implanting suckling heifer calves at 2-4 months of age will increase growth rate, but this research indicates some potential for reduction in reproductive performance.

Relationships Between Lignin Content And Fermentability Of Intact And Chemically Treated Big Bluestem Fiber, R.C. Cochran, G. Towne, Evan C. Titgemeyer, K. C. Olson

Kansas Agricultural Experiment Station Research Reports

An accurate assessment of forage quality is required to allow prediction of animal performance. One of the most commonly used methods of forage evaluation is to measure lignin content, with more heavily lignified materials being considered less digestible. Two measures of lignin, acid detergent lignin (ADL) and acetyl bromide lignin (ABL), were assessed with regard to their ability to predict forage digestibility. Big bluestem forage samples were collected from three ungrazed, annually burned pastures at 38, 58, and 97 days postburn. These times were selected to represent a broad range of forage quality. Cell wall material was treated chemically by: …

Kansas Agricultural Experiment Station Research Reports

A total of 416 pigs (initially 9.36 Ib and 15 d of age) was used in a 28-d growth assay to evaluate the effects of spray-dried plasma source on starter pig performance. Pigs were blockedby weight and allotted to one of four dietary treatments in a randomized complete block design. Three spray-dried plasma sources were tested: bovine, porcine, and plasma collected from only sows. Plasma sources and lactose replaced skim milk in the control diet to form the experimental diets. Experimental diets were fed during Phase I (d 0 to 14 postweaning), and all pigs were fed a common Phase …

Kansas Agricultural Experiment Station Research Reports

Eighty crossbred gilts (initially 134 lb) were used in a growth assay to evaluate the effects of supplementing finishing pig diets with betaine and (or) choline on growth performance and carcass characteristics. Betaine at 0 or 1000 ppm and choline at 0 or 100 ppm were used in a 2 x 2 factorial arrangement in eight randomized complete blocks. A fifth treatment, 1000 ppm betaine from a liquid, 16 carbon betaine (Lonzaine 16, distributed by Lonza, lnc., Fair Lawn, NJ), was added to further evaluate the efficacy of another form of betaine. Pigs were blocked by weight and ancestry and …
