Effects of alfalfa and cereal straw as a forage source on nutrient digestibility and lactation performance in lactating dairy cows.
This study was conducted to investigate the nutrient digestibility and lactation performance when alfalfa was replaced with rice straw or corn stover in the diet of lactating cows. Forty-five multiparous Holstein dairy cows were blocked based on days in milk (164 ± 24.8 d; mean ± standard deviation) and milk yield (29.7 ± 4.7 kg; mean ± standard deviation) and were randomly assigned to 1 of 3 t...
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...
متن کاملEffect of Milking Frequency on the Lactation Performance and Lactation Curve of Holstein Dairy Cows in Iran
The aim of this study was to investigate the effect of milking frequency (three times daily vs. two times daily) on the lactation curve shape, partial and 305-d lactation performance in Holstein dairy cows in Iran. Data from February 2000 to December 2012 comprising 217345 lactations on 141364 cows distributed in 324 herds collected by the Animal Breeding Center of Iran were used. The mean milk...
متن کاملEffect of corn snaplage on lactation performance by dairy cows
The objective of this study was to determine lactation performance by dairy cows fed corn snaplage either alone (SNAP) or in combination with ground dry shelled corn (SPDC) versus rolled high-moisture shelled corn (RHMC). Dry-matter content was greater for RHMC (78.2%) than SNAP (68.5%). The starch content of SNAP was approximately 10%-units lower than RHMC. Sixty Holstein cows (30 primiparous ...
متن کاملEffect of Live Yeast and Mannan-oligosaccharides on Performance of Early-lactation Holstein Dairy Cows
This study evaluated the effects of live yeast and yeast cell-wall mannan-oligosaccharide supplementation on performance and nutrient digestibility during early lactation in cows fed a diet based on a mixture of corn silage and alfalfa hay as forage sources. Eight multiparous Holstein dairy cows (average days in milk, 27±6) were used in a replicated 4×4 Latin square design. Diets contained 45% ...
