The effects of corn silage particles size and fat supplement on feed intake, digestibility, ruminal function, chewing activity, and performance in mid-lactating Holstein dairy cows
An experiment was carried out to determine the effect of corn silage particle size and fat supplements on performance, solid passage rate through the digestive tract, and chewing behavior in dairy cows. The forages were coarse or fine corn silage with geometric means of 8.8±2.7 and 5.6±2.8 mm, and alfalfa with geometrics means of 7.0±3.3 mm, and fat supplements were neutral fat (palm) and soy-o...
متن کاملEffect of Corn Shredlage on lactation performance and total tract starch digestibility by dairy cows
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...

The chemical composition, in situ ruminal degradability coefficients of dry matter (DM), and nutrient digestibility in sheep were evaluated for corn silage (CS) treated (fresh weight basis) with different levels of a commercial bacterial inoculant (I) as follows: (1) untreated CS (control); (2) CS + I at half of the recommended level; (3) CS + I at the recommended level (3 1010 colony forming...
