Calculating Feed Costs With Alternative Lysine Diets For High-Lean Growth Gilts (1994), K G. Friesen, Michael A. Boland, A P. Schinckel, Jim L. Nelssen Jan 1994

Calculating Feed Costs With Alternative Lysine Diets For High-Lean Growth Gilts (1994), K G. Friesen, Michael A. Boland, A P. Schinckel, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Data from two experiments were used to determine the feed cost per I of lean gain for high-lean growth gilts fed various digestible lysine levels (.54 to 1.04%). The cost for producing 1 lb of lean increased as live weight increased from 75 to 160 lb (Exp 1) and from 160 to 300 lb (Exp 2). However, in Exp I, the cost per lb of lean gain was minimized for gilts fed 1.04 and .94% digestible lysine (1.25 and 1.15% total lysine, respectively) from 75 to 90 lb and from 90 to 160 lb, respectively. These data are similar to …

Injection Of Vitamin A At Insemination And Reproductive Performance In Gilts (1994), D Schoneweis, M Nelson, Duane L. Davis Jan 1994

Injection Of Vitamin A At Insemination And Reproductive Performance In Gilts (1994), D Schoneweis, M Nelson, Duane L. Davis

Kansas Agricultural Experiment Station Research Reports

This experiment tested the hypothesis that an injection of vitamin A on the day of first detected estrus would improve reproductive performance of gilts. Gilts (432) were assigned to either receive vitamin A (1,000,000 IV) or placebo injected intramuscularly on the first day of estrus. No differences in farrowing rate, number of pigs farrowed per litter, or birth weight of pigs were detected. Possibly, gilts do not respond to vitamin A with improved fecundity. Other workers have reported an improvement in litter size for sows. Alternatively, treatment with vitamin A may need to precede estrus to improve litter size or …

Managing High Milk-Producing Herds Ix. Raising Dairy Heifers And Steers: A Business. Surviving Gatt, Nafta, And The 1995 Farm Bill (1994), John E. Shirley

Kansas Agricultural Experiment Station Research Reports

The primary focus of the dairy industry in Kansas has been the milking herd. However, dairy heifer replacements and dairy steers offer income opportunities that have been largely ignored by some Kansas dairy producers. The 1994 Dairy Day program highlights these programs as potential profit centers. An "opportunity cost" analysis comparing the economic returns from your present enterprises with the potential returns from a dairy heifer or steer enterprise might propel you into a new career or enhance the profitability of your total operation.; Dairy Day, 1994, Kansas State University, Manhattan, KS, 1994;

Effect Of Yearly Milk Per Cow On Various Reproduction Traits (1994), Edward P. Call Jan 1994

Effect Of Yearly Milk Per Cow On Various Reproduction Traits (1994), Edward P. Call

Kansas Agricultural Experiment Station Research Reports

An analysis of 4,334 Holstein dairies confirms the negative genetic correlation that exists between milk production and reproduction. The most obvious traits affected are services per conception and conception rate. When subjected to analysis by the KSU Dairy Herd Analyzer (DHA) program, higher-producing herds have less economic loss because their managers do a better job of controlling factors not under genetic control, such as average days dry and age at calving of first-calf heifers (L-1). Higher-producing herds also have fewer cows that are open and should be bred.; Dairy Day, 1994, Kansas State University, Manhattan, KS, 1994;

Evaluation Of Enzyme-Modified Wheat Gluten As A Component Of Milk Replacers For Calves (1994), H. Terui, J.L Morrill, James J. Higgins Jan 1994

Evaluation Of Enzyme-Modified Wheat Gluten As A Component Of Milk Replacers For Calves (1994), H. Terui, J.L Morrill, James J. Higgins

Kansas Agricultural Experiment Station Research Reports

Holstein bull calves (n=120) were assigned randomly to be fed either of five milk replacers (MR) that contained different amounts of crude protein (CP) and protein from wheat gluten (WG) for 6 weeks. Weight gains of calves fed MR containing 20% CP, with either 0, 30, or 50% of the protein coming from WG, were similar, as were gains of calves fed MR containing 18% CP with either none or 33% of the protein from WG. When WG supplied 33% of the protein, calves fed 18% CP gained as much as calves fed MR containing 20% CP. Calves fed MR …

Effects Of Processing Sorghum Grain On Dairy Calf Performance (1994), I.E.O. Abdelgadir, J.L. Morrill Jan 1994

Effects Of Processing Sorghum Grain On Dairy Calf Performance (1994), I.E.O. Abdelgadir, J.L. Morrill

Kansas Agricultural Experiment Station Research Reports

Two trials evaluated the effect of processing sorghum grain on performance of young dairy calves. In trial 1, newborn Holstein calves (49 heifers and 27 bulls) were blocked by age and sex and assigned randomly to each of three calf starters containing either raw, roasted (Jet-Pro®) at 280 degrees F, or conglomerated (Jet-Pro®) sorghum grain. The conglomeration process consisted of grinding the grain, adding water, and pelleting the mixture, then roasting it. Raw and roasted sorghum grains were ground through a .125-inch screen and included in complete pellet starters, whereas conglomerated sorghum grain pellets were mixed with the other ingredients …

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 …

Total Mixed Rations For Feeding Dairy Heifers From 3 To 6 Months Of Age (1994), H. Terui, J.L. Morrill, James J. Higgins Jan 1994

Total Mixed Rations For Feeding Dairy Heifers From 3 To 6 Months Of Age (1994), H. Terui, J.L. Morrill, James J. Higgins

Kansas Agricultural Experiment Station Research Reports

Total mixed rations (TMR) with different forage (F):concentrate (C) ratios were fed to Holstein heifers (n = 135) 12 to 24 wk of age. In four trials, the heifers were divided into different age groups and fed three different F:C ratios. Based on the results, the following recommendations are made. First, if facilities are available for only two groups from 12 to 24 wk of age and heifers are at the desired body weight (BW) at 12 wk of age, they should fed a diet similar to the experimental TMR 50:50 with a F:C ratio of 50:50 from 12 to …

Rate And Extent Of Losses From Top Spoilage In Alfalfa Silages Stored In Bunker Silos (1994), D.L. Holthaus, Matthew A. Young, L. Pfaff, B.E. Brent Jan 1994

Rate And Extent Of Losses From Top Spoilage In Alfalfa Silages Stored In Bunker Silos (1994), D.L. Holthaus, Matthew A. Young, L. Pfaff, B.E. Brent

Kansas Agricultural Experiment Station Research Reports

Alfalfa silages were made in pilot- and farm-scale silos, and five sealing treatments were compared. After 90 days, sealing dramatically reduced dry matter (DM) losses at the 5 and 10 inch depths in the farm silos and at the 0 to 12, 12 to 24, and 24 to 36 inch depths in the pilot silos. Extending the storage period to 180 days in pilot silos had no effect on DM losses for sealed or delay-sealed silages, but DM losses for unsealed silages continued to increase at all three depths. Placing a roof over the unsealed, farm-scale silo increased the silage …

Management Analysis Of Dairy Cow Herd Enterprises In The Kansas Farm Management Association (1994), F.D. Delano, Michael R. Langemeier Jan 1994

Management Analysis Of Dairy Cow Herd Enterprises In The Kansas Farm Management Association (1994), F.D. Delano, Michael R. Langemeier

Kansas Agricultural Experiment Station Research Reports

Actual records of dairy cow herd enterprises from Kansas Farm Management Association farms over the past 4 years have shown an increase in returns over variable costs from $17,900 to $27,000 per farm for a 100-cow dairy herd in favor of herds with higher milkproducing cows. Cost per hundred weight of milk produced per cow decreased for the higher-producing herds compared with lowerproducing herds, even though total cost per cow increased. In 1993, for every extra $1.00 spent on feed and other variable costs, the higher producing herds earned $2.34. This was a 234% return per dollar invested.; Dairy Day, …

Stage Of Lactation Profile Reflects Nutrition And Management (1994), James R. Dunham Jan 1994

Stage Of Lactation Profile Reflects Nutrition And Management (1994), James R. Dunham

Kansas Agricultural Experiment Station Research Reports

The Stage of Lactation Profile (SOLP) is a good estimate of the shape of the lactation curve for dairy herds. The SOLPs for herds with various milk production levels are somewhat similar. The rates of decline of all SOLPs are about the same. Therefore, the differences in production levels are about the same in late stages of lactation and in early lactation, regardless of production Rolling Herd Average (RHA). In addition, higherproducing herds have their highest level of production in the second stage of lactation (51 to 100 days in milk), whereas this occurs in the first stage of lactation …

Ruminal Degradation Of Dietary Protein In Steers Fed Lasalocid (1994), R.H. Wessels, Evan C. Titgemeyer, Jean G. St. Jan 1994

Ruminal Degradation Of Dietary Protein In Steers Fed Lasalocid (1994), R.H. Wessels, Evan C. Titgemeyer, Jean G. St.

Kansas Agricultural Experiment Station Research Reports

A trial was conducted to investigate the effect of lasalocid (Bovatec®) on ruminal degradation of dietary protein in Holstein steers. Five ruminally and duodenally cannulated steers (305 kg) were fed a corn-alfalfasoybean meal diet (17% CP), with or without lasalocid, in a three period, switch-back experiment. Ruminal pH, ammonia, volatile fatty acids, and amino acid and peptide concentrations were unaffected by lasalocid. Lasalocid reduced (P<.05) ruminal protease activity by 15%, but did not change deaminase activity. Digestibilities of dry matter, organic matter, fiber, and crude protein were similar between treatments. Intestinal flows of microbial and feed crude protein fractions, as well as amino acids, remained unchanged when lasalocid was fed. Thus, in this experiment, lasalocid failed to decrease feed protein degradation in the rumen and, therefore, was unable to increase the supply of crude protein or amino acids to the small intestine.; Dairy Day, 1994, Kansas State University, Manhattan, KS, 1994;

Kansas Agricultural Experiment Station Research Reports

The objectives of this experiment were to evaluate bovine and porcine plasma proteins as sources of protein for calf milk replacers and to evaluate a commercial probiotic. Four replacers were compared; an all milk protein control, two replacers with 25% of protein from bovine plasma protein or porcine plasma protein, and a replacer identical to the control except that it contained a probiotic (Biomate FG, Chr. Hansen's Laboratory) instead of antibiotic. The 120 bull calves (7 ± 3 days of age) were divided into four equal groups, and calves from each group were fed 4 quarts per day of one …

Payout Characteristics Of Anabolic Agents From Synovex®, Finaplix®, And Revalor® Implants In Finishing Yearling Steers, P.S. Hickman, Robert T. Brandt Jr., D.M. Henricks, J. Ernest Minton, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Forty, individually fed, yearling steers (750 lbs) were used to measure payout characteristics of different trenbolone acetate-containing implants and to correlate those characteristics to growth response. Treatments were 1) control, 2) Synovex-S®, 3) Finaplix-S®, 4) Synovex® plus Finaplix, and 5) Revalor®. Steers were fed a 12% crude protein, corn-based, finishing diet for 112 days. Compared to Revalor, which had a fairly constant payout over time, the combination of Synovex plus Finaplix resulted in higher blood levels of estradiol and trenbolone acetate (TBA) up to 56 days, followed by a relatively rapid decline to 112 days. Despite elevated levels of TBA …

Effects Of Alfalfa Form And Level On Subacute Acidosis, B.J. Healy, Robert T. Brandt Jr., S.M. Gramlich Jan 1994

Effects Of Alfalfa Form And Level On Subacute Acidosis, B.J. Healy, Robert T. Brandt Jr., S.M. Gramlich

Kansas Agricultural Experiment Station Research Reports

Eight ruminally cannulated crossbred steers (1225 lb) were used to investigate the effects of 5 vs 10% alfalfa hay or pellets on rumen characteristics during subacute acidosis. Alfalfa hay was obtained from one source, and alternate bales were either chopped (3- to 4-inch length) or ground and pelleted (3/8-inch pellet). Intake during the recovery period after feed challenges tended (P=.12) to be greater for diets containing 10% alfalfa. Duration of rumen pH below 5.5 was less for diets with chopped vs pelleted (P<.10) or 10 vs 5% (P<.05) alfalfa. Total volatile fatty acid (VFA) concentrations during the challenge ph ase and for the overall experimental period were increased (P<.05) when steers were fed 5 vs 10% alfalfa diets but were similar during the baseline and recovery periods. The higher pH and lower VFA concentration resulting from feeding 10% alfalfa diets suggest that steers fed a moderate amount of roughage can withstand greater fluctuations in intake without developing acidosis.

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 Stage Of Growth And Sampling Procedure On The Trace Mineral Content Of Kansas Native Grass, J.D. Arthington, L.R. Corah, S.D. Utter Jan 1994

Effect Of Stage Of Growth And Sampling Procedure On The Trace Mineral Content Of Kansas Native Grass, J.D. Arthington, L.R. Corah, S.D. Utter

Kansas Agricultural Experiment Station Research Reports

To determine the trace mineral content of Kansas native grasses, samples were collected from four locations of tall or intermediate grasses and four locations of short grasses. Copper (Cu) and zinc (Zn) levels tended to be lower during dormancy than in the growing season; however, manganese (Mg) and iron (Fe) levels were essentially the same throughout the year. In terms of meeting the dietary requirements of grazing cattle, Cu was adequate in June but marginal in February, whereas Zn was marginal to deficient at both collection times. In addition, the impact of grazing selectivity on the validity of trace mineral …

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 Protected Lysine-Methionine On Gain And Health Of Newly Arrived Calves, F.K. Brazle, Gerald L. Stokka Jan 1994

The Effect Of Protected Lysine-Methionine On Gain And Health Of Newly Arrived Calves, F.K. Brazle, Gerald L. Stokka

Kansas Agricultural Experiment Station Research Reports

Long-hauled calves averaging 293 lb were allotted to groups fed with or without protected lysine-methionine (Smartamine ML®). Protected lysine-methionin e did not improve ADG in the first 28 days but did improve ADG from 29 to 56 days. It also reduced morbidity (16.1 vs 34.2%) from day 29 to 56. Based on this research, the response of long-hauled calves to protected lysine-methionine in the diet appears to occur after they have recovered from the stress of shipment.
