چکیده

A comparison between two distinct levels of back fat thickness in open cows, females not becoming pregnant during the previous breeding season, was carried out order to evaluate their reproductive performance prior next natural mating a seasonal program. Thirty cows from season were divided evenly by age and (BFT) groups. HBFT (high ≥ 70 mm) LBFT (low ≤ mm), values statistically different groups (P < 0.05). The study into three phases which formation CL follicular dynamics recorded ultrasound progesterone. Also, serial monitoring glucose, urea triglycerides studied. fertile bull previously approved soundness evaluation introduced after third phase remained with herd for 90 days. No differences found dynamics; number animals cycling fertility also similar (80%). Differences high scores BFT. In conclusion, decision keeping must be based on an economical advantage farmer.
