Estrus (Heat) Detection Aids in Dairy Animals: A Review
Abstract: In India, as dairy technology is developing day by day, reproductive performance of dairy animals requires regular and accurate heat detection. Heat detection is very useful for proper timing of artificial insemination. Failure to detect estrus (heat) is a major contributing factor for low fertility. New technologies for the solution of this problem must be more effective than visual observation and aids currently used to detect estrus. This paper mainly …

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 …

Reproductive Efficiency of Introduced Gaddi Buffalo (Bubalus bubalis) in Kalikot, Nepal
Abstract: Gaddi buffalo (Bubalus bubalis), indigenous to far-western hills with morphologically larger body and docile temperament is compared to Murrah, distinguished by white patch on forehead and switch. A study was carried out at Raskot Municipality of Kalikot district, Nepal to evaluate the effect of non-genetic factors on reproductive traits of introduced Gaddi on September, 2017 to May 2018. A total of 103 Gaddi buffaloes were purposively selected and survey was …

The 0^0 Thing Behind Everything
Abstract: Physics is the science of the physique of the universe. The physique of the universe is space. Space is the bottom-most of the universe which cannot be further undermined. Space cannot be seen. Not heard. Not smelt. Not tasted. Not touched or felt. Not known. The moment it is seen, heard, smelt, tasted, felt, known, the question pops up: who is the seeing, hearing, smelling, tasting, feeling, knowing? Consciousness/cognizance is …

Reproductive Traits Evaluation of Lime Buffalo (Bubalus bubalis) in Western Hills of Nepal
Abstract: The data pertaining to variable reproduction traits of Lime buffaloes were collected from Baglung and Gulmi during January, 2017 and March, 2018 for evaluation. Total 182 buffalo samples from Baglung and Gulmi were selected and data were collected using semistructured questionnaire and farmers record. Data entry and data analysis was done by using MS-Excel and R-statistical package, respectively. The least square mean comparison was done using Duncan’s multiple range test. …

Chitosan-conjugated GnRH Nanoparticles with AFM Appearance
Abstract: Nanotechnology can provide new tools for molecular and cellular biology, biotechnology, veterinary physiology, reproduction, detection of pathogens and many more. There are several areas such as science, engineering of agriculture, animal and food systems where nanotechnology could be applied. Application of nanotechnology can be employed in the development of sustained release systems of molecules such as hormones, vitamins, antibiotics, antioxidants and nucleic acids. Longer lasting surges in Gonadotropin hormone (GtH) …

Effects of the Embryonic Bisphenol an Exposure on The Postnatal Development, Learning and Memory of Rat Offspring: Fundamental Study
Abstract: We studied the morphologic changes in some organs and changes of learning and memory of the rat offspring after the embryonic bisphenol A exposure. Background: Bisphenol A, widely used as polycarbonate plastics material to manufacture food packaging, toys, glasses, computers, kitchen utensils and medical instruments, is one of the most common endocrine-disrupting chemicals. It is demonstrated that bisphenol A may be mingled with foodstuff and beverage from package and receptacle. …

Climate-Induced Infertility in Dairy Cows: Pathways, Challenges, and Solutions for Sustainable Dairy Development
Abstract: Climate change has emerged as a significant challenge to dairy production, with profound implications for reproductive performance in dairy cows. The interplay of rising temperatures, fluctuating rainfall patterns, and increased frequency of extreme weather events disrupts key physiological, nutritional, and behavioral processes essential for fertility. Heat stress alters hormonal balance, impairs oocyte and embryo quality, reduces estrus expression, and affects pregnancy outcomes. Concurrently, climate-induced nutritional deficits, immune suppression, and increased …

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 …
