Development of an Endocrine Profiles Based Mathematical Model for the Estrous Cycle in Indian Crossbred CowsDevelopment of an Endocrine Profiles Based Mathematical Model for the Estrous Cycle in Indian Crossbred Cows
Abstract: Declined fertility of the high-yielding dairy cows reared under intensive condition of management is of great concern not only for India but for the whole world. The bovine estrous cycle, particularly the estrus, is tightly controlled by the complex interplay of various organs and hormones. Mathematical modeling of the bovine estrous cycle could help in understanding the dynamics of this complex biological system. The authors, therefore, developed a mechanistic mathematical …

Study on Major Reproductive Health Problems and Associated Risk Factors of Crossbred Dairy Cows in and Around Butajira Town, Southern Ethiopia
Abstract: Reproductive problems of cows considerably affect dairy profitability. A study of questionnaire survey and regular follow-up was conducted to investigate major reproductive health problems and responsible risk factors in crossbred dairy cows in and around Butajira town. For this research, a total of 384 crossbred breed dairy cows were randomly selected out of which 41% (n=157) were found to be affected by one or more of the common reproductive health …

The study on the isolation, culture, differentiation and transplantation of neural stem cells from brain of crossbred white rat in the neonatal period
Abstract: We have studied for isolating neural stem cells from brain tissue of neonatal crossbred white rat, culturing and transplanting into local cerebral ischemic reperfusion model rat. We performed digestion of brain tissue, primary culture and subculture of segregated cells, measured number of neurosphere and growth index and ratio of cell survival, and identified expression of nestine from cultured cells, investigated engraftment of NSCs into ill brain tissue after transplantation of …

Development of a New Kisspeptin Based Method of Ovulation Synchronization for Crossbred Dairy Heifers
Abstract: The aim of the present study was to develop a new method of synchronization of estrus/ovulation for crossbred cows based on kisspeptin, a potent secretagogue of GnRH. For the purpose, a total of 108 estrous cycles were studied in cyclic heifers. The animals divided equally in to two groups were treated either with ovsynch protocol of estrus synchronization (group-I; GnRH: day 0; PGF2α: day 7 and GnRH: day 9) or …

Successful Management of Dystocia Coupled with Cervicovaginal Prolapse in a Crossbred Cow
Abstract: A three-year-old crossbred cow in first parity was brought to the Referral Veterinary Polyclinic, Indian Veterinary Research Institute, Uttar Pradesh, India, with the history of full-term gestation, unproductive straining and first degree cervicovaginal prolapse (CVP) for past 48 h. Per vaginal examination revealed patent vagina, with only three finger cervical dilation whereas per rectal examination revealed that foetal parts were palpable. The prolapsed mass was replaced after washing with antiseptic …

Successful Treatment of Clinical Ketosis in Dairy Cattle
Abstract: Ketosis is a post-parturient metabolic disease encountered in high yielders due to imbalance in production and feeding leading to gluconeogenesis along with formation of abnormally high levels of ketone bodies. The disorder is particularly seen within the first few weeks after calving. It arises due to a negative energy balance when energy demands for milk production exceed dietary energy intake, leading to excessive mobilization of body fat reserves and resulting …

Heterosis–Genetic Basis and Utilization for Improvement of Dairy Cattle: A Review
Abstract: The phenomenon in which progeny of crosses between inbred lines or purebred populations are better than the expected average of the two populations or lines for a particular trait is known as heterosis. Utilization of heterosis is the main goal of crossbreeding. The amount of heterosis maintained in a herd depends on the type of crossbreeding system selected for breeding. Heterosis includes greater viability, faster growth rate and greater milk …

Influence of Genetic and Non-Genetic Factors on Lactation Traits in Dairy Cattle: A Review
Abstract: India has about 39.73 million crossbred cattle out of total 190.90 million (37.28%) cattle population as per the all India livestock census, 2012. The decade wise trend in livestock population (1997 to 2012) shows a distinctive swing in composition of dairy animal stock in favor of crossbred cattle, as their number increased by 20.18%, while that of indigenous cattle declined by 8.94%. Selection of dairy animals is usually based on …

Challenges of Upgrading Local Cattle with Exotic Breeds: Genetic, Environmental, Economic, and Sustainability Trade-offs
Abstract: The practice of upgrading local cattle with exotic breeds has gained popularity as a strategy to enhance milk and meat production. While this approach holds potential for improving productivity, it also presents a range of challenges that need careful consideration. This study examines the genetic, environmental, economic, and sustainability trade-offs associated with upgrading local cattle with exotic breeds. From a genetic perspective, upgrading can result in the dilution of traits …

Soil Fertility of Grasslands under Influence of Grazing
Abstract: Grazing is one of the important biotic factors that influence the formation and sustenance of grasslands. The present study was undertaken to assess the influence of grazing by different species of domestic herbivores, on the fertility of grasslands. Soil from grasslands grazed by buffaloes, crossbred cattle, and sheep, as well as control grassland restricted from grazing, were compared for different fertility parameters like soil organic carbon, phosphorus, potassium, iron, zinc, …

Impact of invading fish on native species
Abstract: The term "alien species" refers to organisms that have been intentionally or unintentionally introduced outside of their natural range. These organisms have the ability to establish self-sustaining populations, spread beyond the initial point of introduction, and have a negative impact on the environment and the economy. Through crossbreeding with closely related native species, these fish with diverse genetic make-up cause the formation of a new group of organisms with different …
