Light Backscatter Of Milk Products For Transition Sensing Using Optical Fibers, Frederick A. Payne, Czarena L. Crofcheck, Sue E. Nokes, Klat C. Kang Nov 1999

Light Backscatter Of Milk Products For Transition Sensing Using Optical Fibers, Frederick A. Payne, Czarena L. Crofcheck, Sue E. Nokes, Klat C. Kang

Biosystems and Agricultural Engineering Faculty Publications

Transition sensors are needed, particularly in the dairy industry, for detecting transitions in pipe flow systems from product-to-water or product-to-product (such as from chocolate to vanilla ice cream mix). Transition information is used to automatically sequence valves to minimize product waste. Optical fibers were used to measure light backscatter between 400 and 950 nm as a function of milk concentration in water and milkfat concentration in milk. The normalized response (100% for product and 0% for water) as a function of product concentration in water was approximately logarithmic for skim milk between 400 and 900 nm and approximately linear for …

Predicting The Cutting Time Of Cottage Cheese Using Backscatter Measurements, Czarena L. Crofcheck, Frederick A. Payne, Sue E. Nokes Jul 1999

Predicting The Cutting Time Of Cottage Cheese Using Backscatter Measurements, Czarena L. Crofcheck, Frederick A. Payne, Sue E. Nokes

Biosystems and Agricultural Engineering Faculty Publications

An automated system for monitoring culture growth and determining coagulum cutting time is needed for cottage cheese manufacturing. A light backscatter measurement system was designed and installed in a local cottage cheese manufacturing plant. A cutting time prediction algorithm was developed using parameters generated from the backscatter profile. The cutting time prediction algorithm, Tcut = Tmax + β2 S, used two time-based parameters generated from the backscatter profile (Tmax and S) and one operator selected parameter, β2, to predict the coagulum cutting time, Tcut. The standard error of prediction for the algorithm was 6.4 …

Effects Of Temperature And Humidity On Cow Respiration Rates In Three Kansas And Two Nebraska Freestall Barns (1999), Joseph P. Harner, John F. Smith, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

Temperatures and humidities outside and inside freestall barns and cow respiration rates were monitored on three Kansas and two Nebraska commercial dairy farms during the summer of 1999. All farms had 4-row freestall buildings with different cooling systems. The first Kansas barn could be cooled naturally and mechanically using evaporative cooling pads located on the east and west walls. The second Kansas barn was ventilated naturally by manually lowering the sidewall curtains and without sprinkling or ventilation systems. The third Kansas barn was ventilated naturally and equipped with fans located over the freestalls and feed-line sprinklers. The first Nebraska barn …


Using The Ovsynch Protocol For Prompt Re-Insemination Of Cows Diagnosed Open At Pregnancy Checks (1999), Jeffrey S. Stevenson Jan 1999

Using The Ovsynch Protocol For Prompt Re-Insemination Of Cows Diagnosed Open At Pregnancy Checks (1999), Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Using the Ovsynch protocol to prepare cows for re-insemination proved to be very effective. Its use guarantees that all cows found open at pregnancy diagnosis are reinseminated promptly within 10 days, and the average pregnancy rate of 28.7% in 136 cows was acceptable. Pregnancy rates were not different whether or not estrus was detected in cows at the timed insemination, but they tended to be greater at second services compared to other repeat services. The Ovsynch protocol is an effective tool to use to ensure prompt re-insemination of open cows.; Dairy Day, 1999, Kansas State University, Manhattan, KS, 1999;

Profit From Pastures, Mark Callow, Martin Van Houtert

Journal of the Department of Agriculture, Western Australia, Series 4

The research program has made a major contribution to the improvement of pasture management techniques, which has, in turn, led to a gain in productivity for dairy farms in the south-west of Western Australia. Analysis has shown a 25 per cent improvement in pasture utilisation, an increase in the average number of cows milked from 155 to 192, an increase in average stocking rates from 0.9 to 1.2 cows per hectare, and increased income from milk sales by $600 per hectare. There are still areas for improvement in sustainability, productivity, and profitability, but the success to date is a credit …

Effects Of Processing And Fat Removal On The Value Of Cottonseed In Diets For Lactating Dairy Cows (1999), M. J. Meyer, Evan C. Titgemeyer, Michael V. Scheffel, A. F. Park

Kansas Agricultural Experiment Station Research Reports

Eighteen Holstein cows were used in six simultaneous 3x3 Latin squares to determine the value of extruded-expelled cottonseed meal with lint as a replacement for whole cottonseed in diets for lactating dairy cows. Diets were: 1) WCS=whole cottonseed; 2) EC+T=extruded-expelled cottonseed meal with tallow; and 3) EC=extruded-expelled cottonseed meal. Diets were formulated to contain 17.5% CP and 40% RUP. Tallow or shelled corn was used to balance energy across diets. No differences were observed in dry matter intake, milk production, or feed efficiency among diets. Cows fed EC produced milk with a slightly higher protein percentage. Feed costs per cwt …

Kansas Agricultural Experiment Station Research Reports

One hundred Holstein heifers were used to examine the effects of monensin (Rumensin®) and lasalocid (Bovatec®) included in calf starter and grower diets. Heifers were assigned alternately at birth to a starter feed containing either Rumensin (28 g/ton, 90% dry matter basis) or Bovatec (40 g/ton, 90% dry matter basis). The Bovatec group was switched to a starter feed containing 28 g Bovatec/ton (90% dry matter basis) at 6 weeks of age. Both groups were switched at 8 weeks of age to grower diets designed to deliver 100 mg/head/day of either Rumensin or Bovatec. No treatment differences were observed between …

Kansas Agricultural Experiment Station Research Reports

Twenty-four pluriparous Holstein cows were used in six 4x4 Latin squares to evaluate the value of extruded-expelled cottonseed meal (EECM) with lint as a source of rumen undegradable protein (RUP) for lactating dairy cows. Cows were fed diets typical of those used by commercial dairies with all the cereal grain supplied as corn. Tallow was used to balance the fat level across diets. Experimental diets were: solvent soybean meal (16% CP:35% RUP)=SBM 16-35; solvent soybean meal (18% CP:35% RUP)= SBM 18-35; extruded-expelled cottonseed meal (16% CP:40% RUP)=EC16-40; bloodmeal/ fishmeal (16% CP:40% RUP)=BMFM 16-40. Average milk production was approximately 82 lbs …

Effect Of Protein Level In Prepartum Diets On Postpartum Performance Of Dairy Cows (1999), A. F. Park, Evan C. Titgemeyer, Michael V. Scheffel, M. J. Meyer

Kansas Agricultural Experiment Station Research Reports

Seventy-five Holstein cows were used in a randomized complete block design to determine the level of dietary protein required to support metabolic functions and maintain body reserves during the periparturient period and subsequent lactation. Cows fed the 14.7% protein diet prepartum had a more ideal body condition score during the entire prepartum and postpartum periods. During the first 90 days of lactation, few consistent differences occurred among prepartum diets for milk production, but the response to rbST was greatest for cows fed 11.7, 13.7 or 14.7% protein prepartum. Full 305-day lactation records showed the most milk, fat, and protein for …


Evaluation Of Wet Corn Gluten Feed As An Ingredient In Diets For Lactating Dairy Cows (1999), M. J. Vanbaale, Michael V. Scheffel, Evan C. Titgemeyer, John E. Shirley Jan 1999

Evaluation Of Wet Corn Gluten Feed As An Ingredient In Diets For Lactating Dairy Cows (1999), M. J. Vanbaale, Michael V. Scheffel, Evan C. Titgemeyer, John E. Shirley

Kansas Agricultural Experiment Station Research Reports

Thirty-two Holstein cows were used in two 2x2 Latin squares with 28-day periods to evaluate the effect of including wet corn gluten feed in diets for lactating dairy cows. Wet corn gluten feed (WCGF) was fed to cows housed in freestalls at 20% of the diet dry matter. Cows fed WCGF consumed more dry matter, and produced more milk and more energy-corrected milk than cows fed the control diet. Production efficiency was not different between diets. The percentages of fat and protein in milk were not different between diets, but yields of all milk components were improved by including WCGF …


The Use Of Somatic Cell Counts To Identify Cows With Subclinical Mastitis At Calving (1999), J. M. Sargeant, B. J. Pulkrabek, Michael V. Scheffel, A. F. Park Jan 1999

The Use Of Somatic Cell Counts To Identify Cows With Subclinical Mastitis At Calving (1999), J. M. Sargeant, B. J. Pulkrabek, Michael V. Scheffel, A. F. Park

Kansas Agricultural Experiment Station Research Reports

The dynamics of somatic cell counts during the first 10 days in milk were compared among udder quarters of cows with intra-mammary infection at the time of calving and those with no infection present. The study group consisted of 81 cows calving at the Kansas State University dairy research herd between July of 1998 and February of 1999. Cows with an intramammary infection had greater, average, somatic cell counts at calving, and this difference continued throughout the 10-day period. Using a breakpoint of 1,000,000 somatic cells/ml at calving to select animals for culture would have correctly selected 81% of the …

Pregnancy Rates In Dairy Cattle After Three Different, Timed, Breeding Protocols (1999), J. A. Cartmill, S. Z. El-Zarkouny, G. C. Lamb, Jeffrey S. Stevenson Jan 1999

Pregnancy Rates In Dairy Cattle After Three Different, Timed, Breeding Protocols (1999), J. A. Cartmill, S. Z. El-Zarkouny, G. C. Lamb, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Synchronizing ovulation enables dairy producers to inseminate cows by appointment rather than after detected estrus. Three different, timed artificial insemination protocols using different combinations of prostaglandin F2α and gonadotropin-releasing hormone were used to synchronize ovulation in 702 lactating Holstein cows. Cyclicity, pregnancy rate, and embryonic survival rate from each treatment were compared. Our results indicate that all three treatments produced acceptable pregnancy rates in first lactation cows. However, for cows in their second or greater lactation, the treatment using prostaglandin F2α 12 days before the Ovsynch protocol improved pregnancy rates more than the other two.; Dairy Day, 1999, Kansas State …


Labor Requirements For Handling Manure From Concrete Basins (1999), Joseph P. Harner, T. Strahm, David V. Key, T. L. Strahm Jan 1999

Labor Requirements For Handling Manure From Concrete Basins (1999), Joseph P. Harner, T. Strahm, David V. Key, T. L. Strahm

Kansas Agricultural Experiment Station Research Reports

Time requirements for loading a manure spreader and traveling to and from the field varied from 20 to 30 min per load. However, standardizing the data showed that 5 to 7 min were required per 1,000 gal (9,000 lb). The preliminary results of the time motion data indicate about 30 min per cow per year are required for handling manure from a concrete storage basin. These results were consistent among the four dairies evaluated, even though differences existed in operating procedures. These results enable dairy producers to assess labor and equipment needs for performing the various operations associated with hauling …


Nutrient Analysis Of Sand-Laden Dairy Manure (1999), T. Strahm, Joseph P. Harner, David V. Key, James P. Murphy Jan 1999

Nutrient Analysis Of Sand-Laden Dairy Manure (1999), T. Strahm, Joseph P. Harner, David V. Key, James P. Murphy

Kansas Agricultural Experiment Station Research Reports

Nine concrete storage basins were sampled on Kansas dairies and analyzed for nutrient content of sand-laden dairy manure. The manure average 75% moisture content during the three sampling periods. The average total nitrogen, phosphate, and potash were 9.7, 4.6, and 7.4 lb/ton, respectively. The data collected from the basin indicated that when the scraped manure from a dairy is applied at an agronomic rate of 15 tons or less per acre, accumulation of nutrients should be minimal, in particular phosphorus. The manure value was $3 to $4 per ton depending on whether commercial sources of phosphorus normally would be applied …


Supplemental Progesterone Increases Pregnancy Rates And Embryo Survival In Lactating Dairy Cows (1999), S. Z. El-Zarkouny, J. A. Cartmill, Jeffrey S. Stevenson Jan 1999

Supplemental Progesterone Increases Pregnancy Rates And Embryo Survival In Lactating Dairy Cows (1999), S. Z. El-Zarkouny, J. A. Cartmill, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Administering progesterone to lactating dairy cows has sometimes proven effective in increasing pregnancy rates. In this study, cows were treated with the Ovsynch protocol in addition to supplemental progesterone given for 7 days between the first gonadotropin- releasing hormone (GnRH) injection and the prostaglandin F2á (PGF2á) injection. Conception rates were greater in lactating Holstein dairy cows receiving exogenous progesterone (62.5%) than in controls treated with only the Ovsynch protocol (35.5%). In addition, progesterone supplementation increased embryo survival between 28 and 56 days of pregnancy.; Dairy Day, 1999, Kansas State University, Manhattan, KS, 1999;
