Abstract

The objective of this study was to estimate and compare the sensitivity of economic efficiency to change in productive and reproductive performance as well as INVOLUNTARY CULLING RATE of dairy herds. For this purpose, a bio-economic model developed in DairyVIP software was used to analysis the registered information in the annual performance of dairy farms covered by Isfahan Vahdat cooperation. The net ANNUAL PROFIT obtained 23310×1000 IRR when the average annual of milk yield, pregnancy rate and annual INVOLUNTARY CULLING RATE were 11588 kg, 8. 6% and 18. 1%, respectively. The ANNUAL PROFIT was 1353×1000 IRR per 1 kg change in the DAILY MILK YIELD. While for every 1% change in the conception and INVOLUNTARY CULLING RATE, the ANNUAL PROFIT varied by 564 and 321×1000 IRR, respectively. The BREAKEVEN of DAILY MILK YIELD and pregnancy rate was too changeable to stay the annual interest, so that an increase in DAILY MILK YIELD by 5 kg could tolerate a decrease in pregnancy rates up to 8. 1%. Whereas pregnancy rate should be increased as much as 26. 6% of basic conditions to compensate the economic losses due to a decline in DAILY MILK YIELD by 5 kg. Our finding can help the farmers to identify the economic value of important traits in cattle ANNUAL PROFITability and make the optimal management decisions to improve economic benefit.
