Reproductive Challenges of High Producing Dairy Cows
Within a dairy herd, total milk production is determined by the proportion of cows producing milk at any given time and the level of milk production of the individual cows within the herd. Improving reproductive efficiency helps to maintain the maximal number of cows producing milk at optimal levels. Reproductive efficiency in dairy cattle currently is suboptimal primarily due to four factors: ...
متن کاملImproving Dairy Cattle Reproductive Performance
• A calving interval of 13.5 months is an achievable goal that will produce higher daily milk yield and higher milk yield over the length of the lactation. To achieve this goal average days to first service should be <80, yearly 21-day Pregnancy Rates should average >20% and culling for reproductive failure should not exceed 10%. • Management must set standard operating procedures for all aspec...
متن کاملReproductive Performance Definition in Dairy Cattle: Affective Factors
The reproductive performance of a dairy herd has a significant effect on the profitability of that herd. Common measures of reproductive performance are days to first service, days to conception, calving interval, services per conception, conception rate, estrus detection rate, and pregnancy rate. Most cow operations would benefit economically by reducing the number of operational days, decreas...

متن کاملFurosemide 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...
