چکیده

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, decreasing culling rates due to non-pregnant females, and shortening their calving interval. several factors influence reproductive performance, but none require more visual attention than heat or estrus detection

Improving 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...

Economic consequences of reproductive performance in dairy cattle.

The net economic value of reproductive efficiency in dairy cattle was estimated using a stochastic dynamic simulation model. The objective was to compare the economic consequences of reproductive performance scenarios ("average" and "poor") of a cow having a good reproductive performance and to explore which reproductive factors have an important impact on economic efficiency. A "good" reproduc...

Nutritional interactions with reproductive performance in dairy cattle.

Increased capability for milk production has been associated with a decline in fertility of lactating cows. Nutritional requirements increase rapidly with milk production after calving and result in negative energy balance (NEBAL). NEBAL delays the time of first ovulation through inhibition of LH pulse frequency and low levels of blood glucose, insulin and insulin-like growth factor-I (IGF-I) t...
