Performance of lactating dairy cows fed sunflower or corn silages and concentrate based on citrus pulp or ground corn

Comparison of feeding corn silages from leafy or conventional corn hybrids to lactating dairy cows.

Three corn hybrids (Pioneer 36F30, Mycogen TMF2450, and Mycogen TMF2404) were compared for yield and quality traits, and lactation performance and apparent digestibility by Holstein cows. The three corn silages were harvested at a target of 33 to 35% dry matter. Before harvest, six corn plants were randomly selected for plant fractionation. Grain-to-stover ratios were 0.92, 0.70, and 0.95 for t...

Effects of Supplementing Xylose‐Treated Soybean Meal or Untreated Corn Gluten Meal to Lactating Dairy Cows

This experiment was performed to investigate whether feeding xylose-treated soybean meal (XSBM) or corn gluten meal (CGM) is economically better under field conditions. Ninety-four multiparous early lactating Holstein cows (55±5 days in milk and 2.82±0.41 body condition score) were used in a completely randomized design. Cows were randomly assigned to one of two treatments: XSBM or CGM as the m...

Influence of corn silage particle length on the performance of lactating dairy cows fed supplemental tallow.

The objective of this study was to determine if the length of chop of processed corn silage influences the impact of supplemental fat on rumen fermentation and performance of dairy cows. We hypothesized that increasing forage particle length may alleviate the interference of fat on rumen fermentation. Sixteen Holstein cows averaging 120 d in milk were used in a replicated 4 x 4 Latin square des...

Productive Performance of Lactating Buffaloes Fed RationContaining Sugar Beet Tops and Corn Silages

Sixteen multiparous lactating buffaloes after 8 weeks of calving and weighing 500 to 600 kg were used in a complete switch-back design with four groups. Buffaloes in the first group were fed the control ration (R1) consisted of DM basis of 60% concentrate feed mixture (CFM)+20% rice straw (RS)+20% berseem hay (BH), while in the other groups the rations consisted of DM basis of 40% CFM+20% RS+40...
