Abstract
The present study was conducted on postpartum anoestrus crossbred (CB) cows
to evaluate the effect of seasons on estrus induction and conception rates and to monitor
the plasma progesterone, biochemical and macro-minerals profiles.
This study conducted during March to June 2015 (summer) and November 2015
to February 2016 (winter) in the villages of milk shed areas of Panchamrut Dairy,
Godhra and Amul Dairy, Anand, and at LRS, AAU, Anand using three protocols, viz.,
(i) Ovsynch (ii) Heatsynch and (iii) Triu-B on 43 anoestrus CB cows during winter
(n=11 in each protocol) and on 40 anoestrus cows during summer seasons (n=10),
keeping 10 cows as untreated anoestrus controls in both the seasons. All the animals
were initially dewormed using Inj. Ivermectin @ 100 mg s/c and treated with i/m
injection of inorganic phosphorus (Inj. Alphos-40 @ 10 ml, Pfizer Animal Health,
Mumbai) and Multivitamins AD3E (Inj. Vetacept @ 10 ml, Concept Pharma, Mumbai)
and were supplied with multi-minerals bolus (Minotas, Intas Pharma, Ahmedabad) @ 1
