Abstract

Repeat breeding is one the most common reproductive disorders that hinders favorable productivity in domestic animals. Repeat breeding in dairy cows not only affects the fertility of the cattle to a considerable extent but also incurs great economic loss to the farmer. Biochemical profile can indicate the nutritional status and help in diagnosis and management of infertility in animals. Present study explores the implication of some biochemical parameters (total protein, bilirubin and some macro minerals as calcium, inorganic phosphorus and magnesium) on normal cyclic breeding process of Bangladeshi dairy cows. Current observation indicates that the lower calcium, inorganic phosphorus and magnesium concentrations might be associated with the ovulatory disturbances in repeat breeder cows. On the other hand, total protein and bilirubin do not play a significant role in causing repeat breeding problem in those cows. Thus, this study provides supportive evidence about the importance of calcium, inorganic phosphorus and magnesium in the resumption of repeat breeding condition. Asian J. Med. Biol. Res.

Summary

Introduction

The production performances of this cattle population are generally low They possess higher genetic biodiversity and popularly known for their higher reproductive efficiency. According to the livestock and poultry survey in 1988-89, there are 20.36 million cows in Bangladesh These are mainly Bos Indicus (Zebu), which are generally small in size and slow, in growth. They are low in weight and produce comparatively less milk. Reproductive problems are common cause of profit loss to the farmers as far as dairy farming and as well as beef production. Infertile animal mean a direct loss in milk production, whereas reduced calf crops hamper the selection efficiency in long-term dairy herd improvement (Dhaliwal 2005). The breeding efficiency of dairy cows is lowered by a number of reproductive disorders like endometritis, anestrus and repeat breeding resulting in great economic losses to the dairy farmers (Dutta and Baruah, 1988)
