Effect of melatonin on some hormonal and physiological responses during different seasons in goats
To study the effect of melatonin during different seasons on some hormonal and physiological responses in goats, twenty four (24) apparently healthy, non-pregnant, non-lactating goats, having approximately similar body weight and age group reared under uniform managemental husbandry practices was selected from Livestock Farm Complex, College of Veterinary Science and Animal Husbandary, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya. The experiments were carried out in spring, summer, autumn and winter seasons in the year 2023. 5 ml/animal blood sample with and without anticoagulant in vials was collected at 0 day, 7 day, 15 day, and 30 day. Anticoagulant added blood was used for Plasma collection. Plasma cortisol, plasma estrogen and plasma progesterone was found significantly (P<0.05) higher in T1,T2 and T3 as compared to control in spring season and similar result was found in summer, autumn and winter season.
Molecular analysis of 18S ribosomal gene of Sarcocystis fusiform infecting buffaloes of semi-arid region of India
Molecular characterization of Sarcocystis fusiformis isolated from semi -arid region of India was done by subjecting the amplified products of 18S rDNA gene (approximately, 900bp) to gene sequencing and RFLP. Two S. fusiformis specific fragments of approximately 768bp and 99bp were seen in all the four PCR products after digestion with restriction enzyme (Dra1). Out of four, gene sequencing results were obtained successfully for one macroscopic, one microscopic and one pellet of bradyzoites which were then submitted in NCBI to receive accession number. Genes of Mathura isolates were aligned with published sequences of Sarcocystis spp. taking Neospora caninum and Theileria annulata as out-groups. Three isolates of Mathura showed more than 99% homology in nucleotide sequence among themselves. Gene sequencing and phylogenetic analysis showed Mathura isolates closer to S. fusiformis isolates of different geographic locations.
Diversity of Tartary Buckwheat (Fagopyrum tataricum Gaertn.) Germplasm from Himalayan region of India: Validation through Morphological traits and SSR markers
Tartary buckwheat (TB; Fagopyrum tataricum Gaertn.) is a nutritional, multigrain crop. Increasing population pressures, urbanization, and the dissolution of traditional culture have led to a sharp fall in Tartary buckwheat landrace coverage. Morphological and molecular diversity of 43 Tartary buckwheat genotypes were assessed based on 9 morphological traits of plants and 59 simple sequence repeat (SSR) markers, respectively. The analysis was done with standard statistical procedures, Mahalanobis D2 statistics and principal component analysis were used for the morphological analysis. Molecular analysis was done using NTSYS-pc software. Analysis of variance revealed that there is adequate genetic variation for all traits. High genotypic correlation coefficients (GCV) and phenotypic correlation coefficients (PCV) was observed for seed yield per plant. High heritability coupled with high genetic advance was observed for seed yield per plant. Correlation analysis revealed that seed yield per plant had positive correlation with days to 80 % maturity. Path analysis revealed that direct positive effects of plant stand at harvest followed by plant height towards seed yield per plant. Based on the polymorphism displayed by SSR markers, a dendrogram was developed and forty-three genotypes were grouped into four clusters. Data for diversity from the morphological and molecular analysis were found to be similar. On the basis of divergence studies, following genotypes viz., IC-329393, IC-42418 and IC-107605 were found most promising for future hybridization programs. On per se performance, the highest-yielding genotype was IC-42418, genotype IC-341591 had the highest crude protein content and the genotype IC-318859, was found to be superior for most of the traits.
Efficacy of Exogenous Melatonin on Hemato-Biochemical and Immune Status of Muzaffarnagari Sheep in Different Seasons
The aim of this research is to examine the seasonal effects of exogenous melatonin supplementation on the immune system and hemato-biochemical parameters of Muzaffarnagari sheep. This study set out to determine whether melatonin may improve physiological indicators that are vital to sheep's health. The research was place at the study was conducted in Department of Veterinary Physiology and Biochemistry, College of Veterinary Science and Animal Husbandary Acharya Narendra Deva University of Agriculture and Technology Uttar Pradesh. After melatonin was given, there were noticeable changes in hemoglobin levels, leukocyte profiles, and red blood cell count, according to hematological research. Seasonal fluctuations were associated with changes in total protein levels and immunoglobulin concentrations, suggesting that melatonin may play a role in regulating immunological function. Melatonin supplementation may have therapeutic applications in livestock management, and the results highlight the impact of seasons on sheep physiology. The results of this study add to our understanding of how melatonin improves sheep health in a variety of settings by shedding light on how it affects hemato-biochemical and immunological responses.
EFFECT OF EXOGENOUS MELATONIN ON PHYSIOLOGICAL AND OXIDATIVE STRESS IN MUZAFFARNAGRI SHEEP
The effects of external melatonin on Muzaffarnagri sheep's Endocrine function, Physiological parameters, and Oxidative stress are examined in this study. The study, which took place at Acharya Narendra Deva University of Agriculture and Technology Uttar Pradesh, in College of veterinary science Ayodhya. Divided the participants into 4 groups: one that received melatonin and another that did not receved the drug. Important metrics tracked were levels of the stress hormone cortisol, activity of the antioxidant enzyme superoxide dismutase (SOD), and vital signs such core Body temperature, Pulse rate, and Respiration rate and Heart rate. Was measured during trail period The results showed that the group treated with melatonin had significantly lower cortisol levels, indicating less stress. An increase in superoxide dismutase (SOD) activity was indicative of better antioxidant defense in the treated group. Melatonin had a beneficial effect on the sheep's health as a whole, as indicated by the increased stability of their physiological markers. Supplementing ewes with melatonin may improve their health and productivity by reducing stress and oxidative damage, according to this study.
