Repeat Breeding In Dairy Animals

Because of the lockdown from the beginning of 2020, many educated young people in the age group of 25-35 has been moved to their hometown and villages. This has compelled them to work online from home and thinking to explore the possibility of animal keeping. This includes fish, goats, buffalo, Desi cows and the exotic cows. All of these the exotic cow seems to be more promising because it gives milk every day and it is a good source of income. Because of the green revolution have been irrigated area of western U.P., Haryana, Punjab, Gujarat and MP. With the introduction of the high yielding exotic breeds of North American and European origin it is very much possible to produce 100 litres of milk from 10-15 animals. These animals survive very well on the agriculture by-products like wheat straw and paddy straw has meant the production of milk without land. The keeping of the exotic cows like Jersey and Holstein has become a leading business to the property dealer, hotel owners and the educational institutions. With the availability of inputs like disease control, reproduction, nutrition, management, and environmentally controlled housing has meant the keeping of dairy animal as an investment. In the recent time the availability of the frozen sexed semen producing only the female calves has revolutionized the dairy industry. The rate of replacement of herd is has doubled. Mostly the cow and buffalo are purchased from Punjab, Haryana and western UP. The cost of transportation from these area is very high. It is necessary for farmer to produce cows or buffalos along with the production of milk. The biggest constrain in this venture is repeat breeding. The failure of conception after repeated artificial insemination service, this is too much discouraging and this involves factors like quality of semen, trained personals, reproductive technology, nutrition, control of blood parasites, internal parasites and external parasite, and pathological conditions of the uterus etc. In this book from my experience of last 50 years in teaching the cow reproduction and treating the animals for repeat breeding I have sum up the different causes of failure. Hope these suggestions given in this book will help the dairy farmers to know some of the reasons for the failure of conception resulting in repeat breeding. Your suggestions and criticism in improving this book will be appreciated.

Artificial Insemination and Treatment of Infertility in Dairy Animals by Honnappagol and Tandle is a handy work of 16 well experienced faculties drawn from different departments of higher learning. Most of them are actively engaged in under-graduate and post-graduate teaching with considerable expertise. Adequate care has been exercised by the editors to incorporate all the aspects of artificial insemination and infertility in the chapters form 1 to 20 so that it can serve as a real guide to the students and veterinarians and in turn minimizing the possible economic losses to the dairy animal owners and dairy Industry. Adequate care has been taken to include all spheres of infertility starting from endocrinology of estrous cycle, role of nutrition, feed formulation, breeding strategies, estrus detection aids, recent advances in reproduction controlled breeding, fertility improvement use of ultrasound and laparoscopy, therapeutic management of infertility and reproductive disease control. Practical knowledge and skill in respect of handling, storage and evaluation of frozen semen, safety handling of cryocans and liquid nitrogen, factors affecting success rate in artificial insemination programme and drugs and hormones used in treating reproductive disorders is also provided.

The historical background. Specification of objectives. Factors determining genetic responses to selective breeding. Herd foundation. Female selection. Male selection. Implementation of breeding programmes.

This textbook provides a detailed view of the different ways in which reproduction in cattle, sheep, pigs and horses can be controlled and manipulated. It is primarily of interest to students of animal science and veterinary medicine, but will also be of use to those who are concerned with the practical aspects of reproduction control, whether in an advisory capacity or in applying techniques on the farm itself. A major objective of the book is to draw attention to information which may be used directly to increase the efficiency of the livestock industry.

Profitable dairy farming, breeding better dairy cattle, principles of nutrition and feeding practices, reproduction and lactation, herd management, marketing.

Better validation of indigenous domestic animal genetic resources is becoming more important with regard to the potential of livestock for poverty alleviation and income generation. To improve indigenous breeds for sustainable income and employment generation, the methods to be employed are the same as developed in systematic breeding programs, be it for cross-breeding or selective breeding within a specific breed. This book systematically introduces the reader to the breed improvement theory and illustrates the theory with practical examples and case studies. The book is addressed to animal science teachers, to undergraduate and postgraduate students as well as to decision makers in the state and central livestock departments.
