Successful Induction Of Estrus During Lactation For Sows Separated From Their Litters (1984), Jeffrey S. Stevenson, Duane L. Davis Jan 1984

Successful Induction Of Estrus During Lactation For Sows Separated From Their Litters (1984), Jeffrey S. Stevenson, Duane L. Davis

Kansas Agricultural Experiment Station Research Reports

Our objective was to determine the effectiveness of inducing estrus during lactation by temporarily separating the litter from the sow during the last week of lactation. Lactating sows were removed daily from their litters for either 1) 3 hr /day (n=20), 2) 6 hr /day (n=39), or 3) 12 hr /day (n=10) during the last 8 days of lactation and exposed to an intact boar for at least 1 hr during the separation period. Litters were weaned from control sows at either 2 (n=13) or 4 (n=15) weeks for comparison of intervals to estrus following complete weaning or temporary separation. …

Effects Of Exposure To Boars And Other Gilts On The Estrous Response After Synchronization With Altrenogest (1984), Duane L. Davis, Jeffrey S. Stevenson Jan 1984

Effects Of Exposure To Boars And Other Gilts On The Estrous Response After Synchronization With Altrenogest (1984), Duane L. Davis, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Estrus was synchronized in gilts by feeding altrenogest for 18 days. All gilts were penned in gestation stalls. Beginning the day before the last altrenogest treatment and continuing until 3 days after treatment, gilts were either exposed to a boar for 2 hr /day, group-penned with other gilts for 2 hr /day, both exposed to a boar and group-penned, or given neither treatment. Boar exposure shortened the interval to estrus but group-penning had no effect. None of the treatments improved the synchrony of estrus.; Swine Day, Manhattan, KS, November 15, 1984

Performance Of Young Pigs Fed Sorghum Grain Damaged By Lesser Grain Borer Or Fungal Invasion (1984), J C. Dietz, Keith C. Behnke, C W. Deyoe, G L. Allee

Kansas Agricultural Experiment Station Research Reports

Nutritional quality and physical conditions were used to evaluate grain sorghum damaged by either the lesser grain borer Rhyzopertha dominica (F.) or by nontoxin-producing fungi. Experimental treatments were: 1) control 04.0% moisture), 2) lesser grain borer (LGB) (14% moisture with initial infestation of 4.5 adults/lb of grain) and 3) fungal (Fungal) (15.5% moisture). Control grain was used to formulate a 17% crude protein diet. The remaining dietary treatments were formulated by replacing the control grain with the two damaged grains on a weight basis. Forty-five female Yorkshire and 12 crossbred male pigs, with an average initial weight of 22 lb …

Litter Size In Gilts After Altrenogest And Flushing (1984), Duane L. Davis, Jeffrey S. Stevenson, D S. Pollmann, G L. Allee

Kansas Agricultural Experiment Station Research Reports

Effects of estrous synchronization and flushing on litter size in gilts were compared on two farms. Estrus in gilts was synchronized with altrenogest for 14 days or estrous cycles were left unaltered (control group). One-half of the synchronized gilts were flushed by feeding supplemental ground milo (3.4 lb) in addition to 4 lb of a basal milo-soybean meal diet that all gilts received. Additional milo was provided from day 8 of altrenogest treatment until the first day of estrus. Response on the two farms differed. Altrenogest-treated gilts from one farm farrowed about one more pig than controls, regardless of whether …

Limiting Amino Acids In Sorghum Grain Protein For Adult Female Swine (1984), A J. Thulin, G L. Allee, D S. Pollman Jan 1984

Limiting Amino Acids In Sorghum Grain Protein For Adult Female Swine (1984), A J. Thulin, G L. Allee, D S. Pollman

Kansas Agricultural Experiment Station Research Reports

Two 4 x 4 Latin square designs were used with 16 gilts at 10 mo of age and weighing 341 lb (gravid) and 301 lb (nongravid) to determine the limiting nitrogenous factors in sorghum grain protein for adult gravid (70th day postcoitum) and nongravid swine. Supplementation of the fortified sorghum grain diet with lysine increased (P<.05) nitrogen retention in both nongravid and gravid gilts. A further addition of threonine also increased (P>.05) nitrogen retention in both nongravid and gravid gilts. However, addition of both lysine and threonine to the sorghum diet failed to result in nitrogen retention equal to that observed for the control diet. Percentage of nitrogen digested was higher (P<.05) for the control diet than for the basal diet or the two diets with lysine and threonine added. Blood urea nitrogen was reduced (P<.05) when lysine was added to the basal diet with an additional reduction when threonine also was added to the diet. However, the control diet caused higher blood urea values when compared to both supplemented diets. These results suggest that another amino acid may be limiting in the sorghum grain diet supplemented with both lysine and threonine. These data and other published data demonstrate that lysine and threonine are the first and second limiting amino acids in sorghum grain for adult gravid and nongravid swine.; Swine Day, Manhattan, KS, November 15, 1984

Immunoglobulin Concentrations In Serum And Nasal Secretions Of Calves At The Onset Of Pneumonia (1984), L.B. Corbeil, B. Watt, R.R. Corbeil, T.G. Betzen Jan 1984

Immunoglobulin Concentrations In Serum And Nasal Secretions Of Calves At The Onset Of Pneumonia (1984), L.B. Corbeil, B. Watt, R.R. Corbeil, T.G. Betzen

Kansas Agricultural Experiment Station Research Reports

Immunoglobulin (Ig) concentrations in serurn and in nasal secretions were correlated with pneumonia and diarrhea during the first 12 wk of life of dairy calves. The peak onset of pneumonia occurred between 2 and 4 wk of age when the calves' serum Ig G1, Ig G2 and IgA concentrations were lowest. As IgG2 concentrations increased, fewer calves developed pneumonia. Peak onset of pneumonia was also correlated with the lowest IgG and IgA concentrations in the calves' nasal secretions. Diarrhea often preceded pneumonia.; Dairy Day, 1984, Kansas State University, Manhattan, KS, 1984;

Prostaglandin F2Α For Lactating Dairy Cows With Silent Estrus (1984), S.S. Plunkett, Jeffrey S. Stevenson, Edward P. Call

Kansas Agricultural Experiment Station Research Reports

Two experiments were conducted in 17 dairy herds in NE Kansas to determine the effectiveness of prostaglandin F2α(PGF) for reducing intervals to conception for cows with silent or unobserved estrus. Cows that failed to be seen in heat so they could be inseminated after calving (Exp. 1) and cows that did not return to estrus after AI and were not pregnant when presented to veterinarian for pregnancy examination (Exp. 2) were assigned alternately to be given PGF or to receive no treatment after detection of a palpable corpus luteum. Cows were inseminated at 72 and 96 hr after PGF treatment …

Factors Affecting Estrus And Fertility Of Holstein Heifers After Prostaglandin F2Α (1984), Jeffrey S. Stevenson, M.K. Schmidt, Edward P. Call Jan 1984

Factors Affecting Estrus And Fertility Of Holstein Heifers After Prostaglandin F2Α (1984), Jeffrey S. Stevenson, M.K. Schmidt, Edward P. Call

Kansas Agricultural Experiment Station Research Reports

Stage of the estrous cycle, time of insemination, and season of the year were examined for their influence on estrus and fertility of 223 Holstein heifers after prostaglandin F2α(PGF). Heifers given PGF early in the estrous cycle (days 5 to 8 where estrus = day 0) had shorter intervals (by 11 hr) to heat than heifers given PGF later in the cycle (days 14 to 16). Heats also were more closely synchronized for heifers treated early in the cycle. Season of the year had no effects on the interval to estrus or on proportion of heifers observed in heat. Conception …

Effect Of Niacin Supplementation On Milk Production And Ketosis Of Dairy Cattle (1984), G. Dufva, E. Bartley, A. Dayton, D. Riddell

Kansas Agricultural Experiment Station Research Reports

Two lactation trials were undertaken to evaluate the effect of a niacin supplement on milk production and 'the physiological symptoms of ketosis. Blood ketone and non-esterified fatty acid levels were lower and blood glucose concentrations higher in niacin-supplemented cows. These trends were exhibited regardless of whether supplementation began 2 wk prepartum or immediately after calving. A 6 g daily dose was found to be of equal or higher benefit than a 12 g supplement. Cows gi ven niacin consistently produced more milk than controls, though the difference was small.; Dairy Day, 1984, Kansas State University, Manhattan, KS, 1984;

Relationship Between Production And Reproduction In 5,480 Holstein Herds Enrolled In The Midstates Processing Center (1984), Edward P. Call, Jeffrey S. Stevenson Jan 1984

Relationship Between Production And Reproduction In 5,480 Holstein Herds Enrolled In The Midstates Processing Center (1984), Edward P. Call, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Reproductive parameters were evaluated in 5,480 Holstein herds involving 335,673 cows to determine the reported negative genetic effect of production on reproduction. While higher producing herds had a slight decline in days to first bred, this effect was offset by a similar increase in services per conception. The greatest effect was seen in the percent of cows open and the average days open. It was concluded that managers of higher producing herds are more aware of the need to get cows bred back after calving and implement the necessary practices to minimize the percent of cows not yet serviced and …
