Milk production response to four different amounts of protein supplementation was measured in a complete lactation study utilizing 58 multiparous Holstein cows treated with bovine somatotropin. The four treatments were as follows (the first number is the dietary crude protein content (% of dry matter) during the first 16 wk of lactation and the second number is the protein content for wk 17 to ...

The objective of this trial was to determine the effect of feeding a TMR containing Corn Shredlage (SHRD; Shredlage LLC, Tea, SD) or conventionally processed corn silage (KPCS) on lactation performance by dairy cows. The KPCS was harvested using conventional rolls (3-mm gap) and set at a 19-mm theoretical length of cut. The SHRD was harvested using novel cross-grooved rolls (2.5-mm gap) and set...

In a 162-day finishing study, steers were fed various levels of dried distillers grains with solubles (DGS) with ground ear corn harvested at 45% moisture, and compared with steers fed 25% DGS, rolled corn, and corn silage. Steers fed the highest level of DGS (37.5% of diet DM) with ground high-moisture ear corn had the lowest ADG and DMI, but F:G tended to be improved by feeding 25% and 37.5% ...

Previous research has shown that eastern gamagrass (EGG; Tripsacum dactyloides L.) will survive winter climatic conditions common throughout central Wisconsin, and will produce yields of dry matter (DM) ranging approximately from 7,000 to 10,000 kg/ha annually when managed with a 1-cut harvest system. The objective of this research was to determine whether the fibrous nature of this perennial w...

A study involving a 2 x 2 x 2 factorial arrangement of treatments was conducted to evaluate effects of hybrid (Pioneer 3335 and 3489), maturity (half milkline and blacklayer), and mechanical processing (field chopper with and without on-board rollers engaged) on intake and digestibility of corn silage. Forty Angus steers (322 +/- 5.2 kg BW) were assigned to the eight silage treatments (five ste...

Sixteen (8 ruminally cannulated) multiparous and 8 primiparous lactating Holstein cows were used in 6 replicated 4 x 4 Latin squares to test the effects of feeding supplemental protein as urea, solvent soybean meal (SSBM), cottonseed meal (CSM), or canola meal (CM) on milk production, nutrient utilization, and ruminal metabolism. All diets contained (% of DM) 21% alfalfa silage and 35% corn sil...

Two experiments were conducted to evaluate effects of barley grains particle size on ruminal pH and ammonia concentration of rams (experiment 1) and carcass characteristics (experiment 2) of male lambs fed high urea diet. Treatments in two experiments were (1: basal diet + whole barley grains, 2: basal diet + ground barley grains with a 5 mm screen, 3: basal diet + ground barley grains with a 3...

This experiment was conducted to evaluate effects of different sources of natural pigments on yolk color and laying hen performance. A completely randomized design with six treatments and six replicates was used.The six experimental treatments were: a control diet containing yellow corn grain, a reference diet containing wheat and barley grain instead of corn; a red pepper diet composed of refe...

Fifteen Holstein cows (10 multiparous and 5 primiparous) in early to mid lactation (79.3 +/- 9.2 d in milk) were used in a multiple 5 x 5 Latin square design with 4-wk periods to evaluate and compare the use of condensed corn distillers solubles (CCDS) and dried distillers grains with solubles (DDGS) in the total mixed ration. The forage portion of the diets was kept constant at 27.5% corn sila...
