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...
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 کاملEconomic Consequences of Paratuberculosis Control in Dairy Cattle Herds
The PTB-Simherd is a dynamic, stochastic, and mechanistic Monte-Carlo model simulating adairy herd including young stock. Paratuberculosis and relevant control strategies against thisdisease was built into an existing simulation model. The model is able to simulate bothepidemiological, technical and economic consequences of paratuberculosis and controlstrategies against it in th...
