Effect of Substituting Steam-Flaked Sorghum for Concentrate on Lactation and Digestion in Dairy Cows

Effects of substituting sorghum grain for barley on milk yield and composition of dairy cows

Effect 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...

Effect 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 ...

The Effects of Macaroni Wastes and Steam-Flaked Barley Feeding in Transition Period on Health and Lactation Performance of HolsteinCows

Thirty two multiparous Holstein cows were used in a randomized block design to investigate the effects of feeding diets included two different source of nonfiber carbohydrate during the transition period on dry matter intake (DMI), lactational performance, blood metabolites and parturitional characteristics. Cows received total mixed rations containing either macaroni wastes(MW) or steam-flaked...

The effect of feeding soybean oil to mid-lactation dairy cows on milk production and composition and on diet digestion

Veira, D. M., Charmley, L. L., Charmley, E. and Lee, A. J. 2001. The effect of feeding soybean oil to mid-lactation dairy cows on milk production and composition and on diet digestion. Can. J. Anim. Sci. 81: 425–428. Mid-lactation Holstein cows were used to test the effect of feeding 3% soybean oil (SBO) on total mixed ration intake, apparent digestibility, milk production, and milk composition...
