Abstract


This study was conducted on 119 Holstein and Montbéliarde dairy cows in
4 pilot farms and one private farm in the semi-arid region of Sétif in eastern Algeria.
The objective of this study is to analyze the reproduction following criteria: the
interval calving-calving (CCI), calving-first insemination interval (CFI1) and the
calving-fecundating covering interval (CFCI). The results obtained show that the
calving-calving interval is on average 381.23 ± 65.56 days with a CV of 16.36%. On
the other hand, the CFCI interval varies between 55.05 ± 39.9 days and 194.61 ±
134.01 days with an average of 105.65 ± 66.65 days and a CV of 62.09%. In addition,
the average fertilization time is judged in the accepted standards, it depends on the
CFI1 interval (88.08 ± 36.02 days) and on the other hand the number of protrusions
per fertilizing projection (1.52 ± 0.78).
