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...
متن کاملEffect of varying dietary ratios of alfalfa silage to corn silage on production and nitrogen utilization in lactating dairy cows.
Twenty-eight (8 ruminally cannulated) lactating, multiparous Holstein cows were blocked by DIM and randomly assigned to 7 replicated 4 x 4 Latin squares (28-d periods) to investigate the effects of different dietary ratios of alfalfa silage (AS) to corn silage (CS) on production, N utilization, apparent digestibility, and ruminal metabolism. The 4 diets contained (dry matter basis): A) 51% AS, ...
متن کاملNutriDense corn grain and corn silage for dairy cows.
Twenty multiparous Holstein cows, 4 of them surgically fitted with ruminal cannulas, were used in a replicated 4 x 4 Latin square to compare the effects of whole-plant silage and grain produced from NutriDense (ND), leafy NutriDense (LND), or a conventional yellow dent (YD) hybrid on ruminal fermentation, total tract nutrient digestibility, and performance of lactating dairy cows. On a DM basis...
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...
متن کاملEvaluation of Urinary Nitrogen Excretion from Plasma Urea Nitrogen in Dry and Lactating Cows
Data of 42 balance measurements from dry and lactating Holstein cows and blood and urine samples from 24 Japanese Black cows were collected to evaluate the potential for predicting urinary nitrogen (N) excretion from plasma urea nitrogen (PUN). Similar positive correlations were obtained between N intake and apparent N absorption in dry and lactating cows. The regression equations of N intake o...
