Two winter steer growth trials were conducted to investigate responses of steer calves to ammoniation of wheat straw, level of alfalfa haylage (50 or 66.7% of diet) and source of supplemental protein, soybean meal (SBM), blood meal (BM), or a blood meal-urea mixture (BM-U). In trial 1, the main effect of arnmoniation significantly increased average daily gain (ADG) from .15 t o .24 kgld, dry ma...

Two studies were conducted to evaluate high-quality tall fescue hay as a supplement to beef cattle fed low-quality roughages. In Exp. 1, 15 ruminally cannulated Hereford x Angus steers (average weight 390 kg) were blocked by weight and assigned randomly to one of three treatments: 1) tall fescue straw, no supplement; 2) tall fescue straw plus tall fescue hay supplement; 3) tall fescue straw plu...

The purpose of this study was to examine the effects fermentation parameters on addition clove oil oat straw, alfalfa hay, and maize silage at a 3% dry matter basis. In vitro gas production, methane production (CH4), metabolic energy (ME), net lactation (NEL), organic digestion (OMD) were all influenced by (P

Background: No studies have been conducted evaluating sugarcane silage associated with both Lactobacillus plantarum and Pediococcus pentosaceus for lactating dairy cows. Objective: To evaluate diets containing different roughages without microbial inoculants on intake, digestibility milk yield of medium-producing Methods: A total 15 Holstein cows distributed into a randomized block design were ...
