Replacing dietary soybean meal with canola meal improves production and efficiency of lactating dairy cows.
Previous research suggested that crude protein (CP) from canola meal (CM) was used more efficiently than CP from solvent soybean meal (SBM) by lactating dairy cows. We tested whether dietary CP content influenced relative effectiveness of equal supplemental CP from either CM or SBM. Fifty lactating Holstein cows were blocked by parity and days in milk into 10 squares (2 squares with ruminal can...
متن کاملEffects 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...
متن کاملEffects of replacing soybean meal with canola meal and decreasing crude protein on milk production and nutrient utilization of dairy cows in early lactation
This study investigated the effects of replacing soybean meal (SM) with canola meal (CM) and decreasing crude protein (CP) levels in CM based diets on performance of dairy cows when different sources of processed grains and CM were used. Canola meal was untreated or roasted at 130°C for 30 minutes and grains sources (corn and barley) were either ground or steamed-flaked. Eight Holstein cows (...
متن کاملCanola Meal as a Protein Source for Lactating Dairy Cows
Canola is an offspring of rapeseed (Brassica napus and Brassica campestris/rapa), which was bred through standard plant breeding techniques to have low levels of erucic acid and glucosinolates. Canola seed is rich in oil, and after oil extraction, the remaining “canola meal” (CM), is a rich protein source used as feedstock to different animal species, mainly dairy cows in North America and in E...
