Effect on Dietary Protein on High-Producing Dairy Cows in Early Lactation

Title: THE EFFECTS OF VARIOUS LEVELS OF DIETARY PROTEIN ON HIGH PRODUCING DAIRY COWS IN EARLY LACTATION

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 ...

Furosemide Induced Electrocardiographic Alterations in High Producing Holstein Dairy Cows

Diuretics have several therapeutic advantages in dairy cows but there are different side effects such as acid-base and electrolyte imbalances which may affect the electrocardiographic parameters. Fifteen multiparous, clinically healthy, non-pregnant and high producing 4-year-old Holstein dairy cows at their early lactation period were randomly divided into 3 equal experimental groups. Furosemid...

Effect of Processing Protein Supplements with Tannin Extracted from Pistachio by-Products on Performance of Holstein Dairy Cows in Early Lactation

This experiment was conducted to evaluate the effects of processing protein meals by tannin extracted from pistachio by-product on apparent total tract digestibility, ruminal fermentation and performance of dairy cows. For tannin extraction, one kilogram of sun-dried pistachio by-products was immersed in four liters of water for 48 h. Then, pistachio by-products were removed from the water and ...

Effect of a mixture of supplemental dietary plant essential oils on performance of periparturient and early lactation dairy cows.

Plant essential plant oils (EO) are volatile aromatic compounds with antimicrobial activity that can alter ruminal fermentation when used as dietary supplements. A feeding trial was conducted to determine the effects of dietary supplementation of periparturient and early lactation dairy cows with a specific mixture of EO. Forty multiparous Holstein cows were randomly assigned to either control ...
