Mithun (Bos frontalis) is a unique free – range bovine species available in the North Eastern hill (NEH) region of India. Recent statistics indicates that the mithun population is decreasing gradually in NEH region. Various factors are influenced and some of the factors are lack of proper feeding management and declining land area for grazing in this region. Greater efforts are required from all quarters to preserve the mithun population to enhance the socio-economic status of this region. There are various methods of feeding system and feeding materials are available in semi- intensive method of mithun rearing in this region. The book has explained about various types and composition of feed block that can be utilized in mithun species under semi- intensive system and this will helpful to select the suitable method and composition of feed block to mithun to increase feed efficiency and to reduce the wastage of feed. This book will help to the mithun farmers and nutrition scientists to improve the nutrient intake at cost effective manner and to reduce wastage of feed in NEH region.

Continued demand of information about breeding, artificial collection, preservation and insemination of duck semen is increasing for the effective utilization of good germplasm for production and reproduction improvement of duck and economy of the duck breeders and farmers. Analysis of seminal parameters of breeding duck is important to utilize for artificial insemination, propagation of good quality duck germ plasm in breeding places. This book has explained about shed management for breeding duck, semen collection, processing, analysis of various seminal, biochemical and enzymatic profiles of semen of duck. Moreover, it explained about in vitro fertility tests and was validated with in vivo fertility (field fertility) trial in duck. The authors hope that this information will be valuable information and increasing the semen production and utilization effectively in duck breeding. This book will be helpful to the duck farmers and duck breeding scientists to improve the reproduction and production of duck in cost effective manner and to reduce the reproductive wastage in duck breeding.

Over the last few years, effect of various concentrations of melatonin on semen preservation was studied in domestic animals and seasonal variation in melatonin production and its effect on semen production, quality were also studied. Melatonin is used as an antioxidant in semen preservation in the present study at various concentrations. Moreover, seminal parameters with various antioxidant and biochemical profiles were studied at different concentrations and at different seasons. Addition of this additive on semen preservation will improve the conception rate and reduces the repeat breeding through better semen preservation. Melatonin helps to select the suitable season to collect the semen to improve the semen preservability. This book will help to the breeders and farmers to improve the fertility in artificial breeding centres and enhance reproductive performance in cost effective manner.

Indigenous breeds of cattle are well adapted to the tropical environment conditions. These breed population is decreasing very drastically in countries like India. Tharparkar is an Indian dual purpose breed. Semen collection and preservation are very important to conserve and preserve this precious germplasm. Production, quality and biochemical composition of semen is affected by seasons. This book explains about semen production, quality and expression of heat shock protein and genes in semen of Tharparkar bulls. This book will be very useful for cattle breeders, researchers and farmers.

The health and disease related information in captive sloth bears is still in a state of infancy in India. Understanding the health related parameters and evidence of diseases in captive-reared bears will be significantly helpful towards enriching the management of captive bears in India. This book is born out of my research work to document the base-line haematological and biochemical data, occurrence of infectious and parasitic diseases, daytime activity pattern in selected captive bears reared, to formulate suitable environmental management measures and to suggest measures that can strengthen the management of health status in captive bears.

Buffalo is the most common milch animal reared after cattle in the world Buffalo has unique ability to utilize coarse feed straw and crop residue and convert them into protein and fat rich lean meat. Today, in buffalo rearing countries, buffalo is recognizing as farmers milk machine. The reproductive performance of buffaloes is not good as compared to the cattle. There are many ways to improve the reproductive performance in buffaloes. The one is proper postpartum management and weaning of buffalo calves. Weaning not only improves the reproductive performance but also increases the milk production and milk yield. This book will help to the buffalo farmers and buffalo researchers how to wean the buffalo calves, period of weaning and alternative milk replacers to calves to increase the reproductive and productive performance in cost effective manner.

Cattle productivity depends largely on reproductive efficiency and is often measured by number of off-spring per breeding animal per unit of time. Cattle suffer to a large extent from the postpartum reproductive disorders which cause great economic losses to the dairy farmers. This is due to lack of essential minerals and vitamins, improper functioning of reproductive organs and poor follicular development in cows. Therefore treatment with different medicaments are essential to control the infertility problem besides proper feeding and health control. This book explains about various treatments including genital massage of reproductive organs on postpartum infertility problem especially postpartum anestrus in dairy cattle and its effects on biochemical profiles of blood. This book will be useful for dairy farmers, cattle breeders and scientists and will enhance reproductive performance in cost effective manner.

Over the last few years, effect of various additives was studied to improve the quality of semen in cattle. These additives include antioxidants, sugars, cholesterol and proteins, etc. Out of which, few are effective and improved the semen quality even in post thaw stage. These additives improve both in vitro and in vivo fertility in all species of animals. Study of these additives will improve the conception rate and reduces the repeat breeding due to poor quality semen. This book will help to the breeders and farmers to improve the fertility in artificial breeding centres and enhance reproductive performance in cost effective manner.

Mithun (Bos frontalis), a unique free – range bovine species available in the North Eastern hill region of India. Recent statistics indicates that the mithun population is decreasing gradually due to lack of suitable breeding bulls, increase in intensive inbreeding practices,etc. in this region. Greater efforts are required from all quarters to preserve the mithun population. Since mithuns are semi wild animal and not fully domesticated, natural breeding is practiced in this species with accompanied limitations like cost and disease transmission. Thus, use of artificial insemination and frozen semen technology for improvement of its pedigree is utmost essential. One cause of decline of semen quality in preservation is due to the action of the reactive oxygen species generated by the cellular components of semen. The effects of lipid peroxidation include irreversible loss of motility, damage to the sperm DNA and fertility. So preservation of mithun semen with anti-oxidants such as catalase (CAT), reduced glutathione, cysteine hydrochloride,trehalose, bovine serum albumin and superoxide dismutase (SOD) are essential to offset lipid peroxidation and enhance the fertility.

Foot and Mouth Disease cause severe economic losses to the mithun farmers in north eastern hilly region especially Nagaland, Manipur, Mizoram and Arunachale Pradesh. Regular preventive and prophylactic vaccination is very much needed in mithun rearing areas. But the vaccination causes severe adverse effects on the reproduction and production performance both in male and female mithun. In this book, effect of FMD vaccination on mithun reproduction especially semen production, semen quality, antioxidant and biochemical profiles of mithun semen are described. This book will be helpful to the mithun breeders and mithun farmers to improve the fertility in artificial breeding centers and will enhance reproductive performance in cost effective manner.
