Diameter of ovarian follicles, estradiol, and progesterone concentrations, and pregnancy rates in cattle treated with progestins and PGF

Smith, M.W; Stevenson, J.S. (Kansas Agricultural Experiment Station, 1994)

Holstein cows and virgin heifers were treated with progestins and PGF before first 2a service to determine their influence on reproductive traits. Control cows were given two injections of PGF 14 days apart and ...
Effect of yearly milk per cow on various reproduction traits

Call, E.P. (Kansas Agricultural Experiment Station, 1994)

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 ...
Effects of processing sorghum grain on dairy calf performance

Abdelgadir, L.E.O; Morrill, J.L. (Kansas Agricultural Experiment Station, 1994)

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 ...
Effects of sunshades on temperature and cow comfort

Shirley, J.E. (Kansas Agricultural Experiment Station, 1994)

Sunshades provide an effective method of reducing ultraviolet sunrays and increasing cow comfort.
Evaluation of enzyme-modified wheat gluten as a component of milk replacers for calves

Terui, H.; Morrill, J.L; Higgins, J.J. (Kansas Agricultural Experiment Station, 1994)

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 ...
Evaluation of milk replacers containing new protein soruces and a probiotic

Morrill, J.L; Laster, J.F.; Morrill, J.M.; Feyerherm, A.M. (Kansas Agricultural Experiment Station, 1994)

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 ...
Influence of source of calories on composition and production of milk

Shirley, J.E.; Gallegos, A.J. (Kansas Agricultural Experiment Station, 1994)

Wheat and tallow increased milk production in a complementary fashion when added to a milo-based grain mix.
Management analysis of dairy cow herd enterprises in the Kansas Farm Management Association

DeLano, F.D.; Langemeier, L.N. (Kansas Agricultural Experiment Station, 1994)

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 ...
Managing high milk-producing herds IX. raising dairy heifers and steers: a business. surving GATT, NAFTA, and the 1995 farm bill

Shirley, J.E. (Kansas Agricultural Experiment Station, 1994)

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. ...
Manure storage structures for small dairies

Harner, J.P.; Murphy, J.P. (Kansas Agricultural Experiment Station, 1994)

Kansas environmental regulations require dairy producers with more than 300 animal units (215 mature cows at 1,400 lb, or equivalent weight) to be able to store the manure scraped from freestalls, lots, alleys, and ...
Raising dairy heifers: a business

Morrill, J.L. (Kansas Agricultural Experiment Station, 1994)

On many dairy farms, improvement is needed in raising replacement heifers, especially in providing proper nutrition and management to allow for freshening at 23 to 24 mo of age at a desirable size. With larger herds, there ...
Rate and extent of losses from top spoilage in alfalfa silages stored in bunker silos

Holthaus, D.L.; Young, M.A.; Pfaff, L.; Brent, B.E.; Boyer, J.E.; Bolsen, K.K. (Kansas Agricultural Experiment Station, 1994)

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 ...
Ruminal degradation of dietary protein in steers fed lasalocid

Wessels, R.H.; Titgemeyer, E.C.; St. Jean, G. (Kansas Agricultural Experiment Station, 1994)

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-alfalfaso ...
Stage of lactation profile reflects nutrition and management

Dunham, J.R. (Kansas Agricultural Experiment Station, 1994)

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 ...
Strategies for small dairy farmers to be profitable and competitive in the future

Cropp, B. (Kansas Agricultural Experiment Station, 1994)

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 ...
Total mixed rations for feeding dairy heifers from 3 to 6 months of age

Terui, H.; Morrill, J.L.; Higgins, J.J. (Kansas Agricultural Experiment Station, 1994)

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 ...
Use of GnRH and PGF for synchronized ovulation and fixed-time inseminations

Stevenson, J.S.; Kobayashi, Y. (Kansas Agricultural Experiment Station, 1994)

Holstein cows and virgin heifers were treated with GnRH and PGF in a novel 2a ovulation synchronization protocol, which involves one fixed-time insemination. One injection of GnRH is given on a Monday morning, followed ...
