Fertility Management Of Dairy Cattle Farms On The Farm CNIAG (El Tarf)

Abstract

This study was carried out in the pilot farm "Ben Hamada" in the municipality of Besbes, wilaya of El Tarf. An analysis of the fertility  results of the campaign (2021-22) was carried out to assess the conduct of dairy cow reproduction. The data collected was processed by the Microsoft Office Excel program for the calculation of means and standard deviation.

A deterioration in the fertility of the herd was noted with a time to reproduction (V- IA1) greater than 186 days and a V-IAF interval of around 329 days, which lengthens the interval between calvings and does not allow to achieve the goal of one calf per cow per year. On the other hand, an improvement in fertility results was recorded throughout the campaign with a percentage of cows at 3IA and above not exceeding 2%.

The reproductive performances recorded remain below accepted standards and lead to considerable economic losses for this farm.
