Kansas Agricultural Experiment Station Research Reports

One hundred forty-four finishing pigs were used to determine the influence of added dietary niacin on their growth performance and meat quality. Gilts grew slower, ate less, and were more efficient than barrows for the entire growth performance period. Increasing dietary niacin levels to 25 g/ton increased ADG in gilts for the first 25 days, but decreased ADG for barrows. No other interactions occurred. From d 25 to 62, ADFI tended to increase for pigs fed up to 100 g/ton niacin, whereas pigs fed 500 g/ton niacin ate less. Dietary niacin level did not significantly affect carcass yield or quality …

Determination Of The Amount Of Wet Corn Gluten Feed To Include In Diets For Lactating Dairy Cows (2000), M. J. Vanbaale, Michael V. Scheffel, Evan C. Titgemeyer, R.U. Lindquist Jan 2000

Determination Of The Amount Of Wet Corn Gluten Feed To Include In Diets For Lactating Dairy Cows (2000), M. J. Vanbaale, Michael V. Scheffel, Evan C. Titgemeyer, R.U. Lindquist

Kansas Agricultural Experiment Station Research Reports

Twenty-four multiparous Holstein cows were used in six 4x4 Latin squares with 28- day periods to determine inclusion rates for wet corn gluten feed (WCGF) in diets for lactating dairy cows. Cows were housed in a tie-stall barn and fed diets to meet or exceed NRC (1989) nutrient requirements. Experimental treatments were 1) control, 2) WCGF constituting 20%, 3) WCGF constituting 27.5%, and 4) WCGF constituting 35% of the diet dry matter. Cows fed WCGF consumed more dry matter (P<0.01) and produced more (P<0.001) milk, energy-corrected milk, and fat-corrected milk than cows fed the control diet. Dry matter intakes were 58.9 lb/day for control and 60.2 lb/day for those cows consuming WCGF diets. Cows fed the control diet produced 83.2 lb/day of milk, whereas those fed WCGF diets produced 91.5 lb/day. Production efficiency was increased (P<0.001) on the WCGF diets. The percentage of fat in milk, total protein production, and milk urea nitrogen were higher (P<0.01) for cows fed WCGF diets than controls. Plasma glucose, total αamino nitrogen, urea nitrogen, and tryglycerides were similar between cows fed the control and WCGF diets. No differences occurred in percentages of protein, lactose, or solids-not-fat content, nor was somatic cell count affected by the addition of WCGF. Body weight and condition score were not affected by treatment. We conclude that WCGF is an excellent feed for lactating dairy cows when included in the diet at 20%, 27.5%, or 35% of the dry matter.; Dairy Day, 2000, Kansas State University, Manhattan, KS, 2000;

Mastitis Management-Effective Methods To Reduce Somatic Cell Counts (2000), John F. Smith, Michael J. Brouk Jan 2000

Mastitis Management-Effective Methods To Reduce Somatic Cell Counts (2000), John F. Smith, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

Mastitis is the most costly health concern in the dairy industry today. Annual losses have been estimated at $180 to 185 per cow. Based on this figure, annual losses for Kansas producers may exceed $15 million. Nationally, mastitis may cost the industry $1.8 billion annually. Although treatment and premature culling for clinical mastitis are costly, about two-thirds of the cost is associated with reduced milk production caused by subclinical mastitis. Effective mastitis control programs are necessary for the dairy industry today. Prevention of subclinical mastitis is the key to lowering the somatic cell counts (SCC). Elevated bulk tank SCC ( …

Kansas Agricultural Experiment Station Research Reports

Sand can be handled successfully either in a scrape or flush system by developing handling systems that allow for the sand-laden manure to settle prior to the effluent entering a lagoon. The abrasiveness and density of sand create problems in handling the manure. Manure weighs about 60 lb/cu ft, whereas sand has a density of 120 lb/cu ft. Sand-laden manure will have an approximate density of 80 lb/cu ft, if 30% of the manure is sand. Because sand is heavier, it will not remain in suspension as long as manure and settles rapidly. Many problems associated with handling sand-laden manure …
