ThesisItem Open Access “Effect of spacing, doses of vermi-compost and salicylic acid on growth and flowering of chrysanthemum (Dendranthema grandiflora Tzvelev)”(Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, 2019) ASHUTOSH; Kumar, MukeshThe present investigation entitled “Effect of spacing, doses of vermi-compost and salicylic acid on growth and flowering of chrysanthemum (Dendranthema grandiflora Tzvelev)” was conducted at Horticulture Research Center (HRC) of Sardar Vallabhbhai Patel University of Agriculture and Technology, Modipuram, Meerut-250110 to standardize the optimum spacing, doses of vermi-compost and foliar application of salicylic acid. Among the treatments, maximum plant spread, number of branches, diameter of flower, weight of flower, shelf life, stalk length, number of flower/plant and flower yield/plant, were recorded with 50 × 75 cm spacing, 10 ton/ha vermi-compost and 100 ppm of salicylic acid spray, whereas, minimum days required for first flower, 50% flowering, NPK content, Bacteria, Fungi, Actinomycetes in post-harvested were recorded with 50 × 75 cm spacing, 10 ton/ha vermi-compost and 200 ppm of salicylic acid spray. However, maximum plant height, number of flower/plot, flower yield/plot, and total flower yield (ton/ha) were recorded with spacing i.e. 50 × 50 cm, higher doses of vermi-compost (10 ton/ha) and 100 ppm salicylic acid. Based on the results obtained from present study, it may be concluded that among all the treatment applied in this study, application of 50 × 50 cm spacing, 10 ton/ha doses of vermi- compost and 100 ppm foliar concentration of salicylic acid was found to be most effective in improving the growth and flowering in chrysanthemum under agro climatic condition in Meerut region of western Uttar Pradesh.ThesisItem Open Access Effect of Transportation Stress on Physiological Performance and immune Function of the Goats.(NDRI, Karnal, 2014) KUMAR, KAMLESH; ASHUTOSHThesisItem Open Access EFFECT OF TREATED EFFLUENT WATER INTAKE ON PHYSIOLOGICAL STATUS, HEALTH AND GROWTH PARAMETERS IN CATTLE AND BUFFALOES(ICAR-NDRI, KARNAL, 2020) RAUTELA, ANKITA; ASHUTOSHThe present study entitled “Effect of treated effluent water intake on physiological status, health and growth parameters in cattle and buffaloes” was carried out with the objective to find out the effect of treated effluent water when offered for drinking on physiological status, health and growth parameters in comparison to control group animals served with fresh tap water. The study was carried out in young and adult animals of cattle i.e. Karan Fries and Tharparkar and buffaloes of Murrah breed at Livestock Research Center of ICAR-NDRI, Karnal. The results of the present study illustrated the physio-chemical and microbial properties of water in accordance with the different drinking water standards such as Dairy NRC, 2001, APHA, EPA 2002 and BIS, 1991. The growth parameters which included body weight, heart girth, paunch girth, height at wither and body length also remained non-significantly (p<0.05) different in treatment groups as compared to the control groups. The young and adult age grouped experimental animals showed no significant (p<0.05) difference in the water and dry matter intake when compared between treatment and control group animals. Similarly while studying the different physiological parameters (Rectal Temperature, Respiration Rate and Heart Rate) and hematological parameters (TEC, TLC, DLC, Hb and PCV) of the animals served with treated effluent water differed from the control values but the differences were however not significant (p<0.05). Biochemical metabolites in plasma samples of treated and control group also showed no significant (p<0.05) variation amongst all the breeds. Different levels of hormones (Cortisol, Aldosterone, ADH, Angiotensin II, T3, T4, Interleukin 2 and TNF α) was measured to see the difference in the animals of control and treatment group, but no significance (p<0.05) was seen. In another study prevalence of parasitic infestation in young calves of these breeds was studied, and presence of endoparasites was found in both the groups. From the recorded observations it can be suggested that the treated effluent water served for drinking did not had any deleterious effect on the physiological and health status of the animals ,therefore this treated effluent water used during the study can be recommended as drinking water to the animals in the water scarce areas.ThesisItem Open Access Physiological Performance of Buffalo and Cattle Calves Under Prevailing Field Conditions During Different Seasons.(NDRI, Karnal, 2014) NANASAHEB, SANAP VAIBHAV; ASHUTOSHThesisItem Open Access ROLE OF AQUAPORINS IN THERMOREGULATION OFBUFFALOES DURING DIFFERENT SEASONS(ICAR-NDRI, KARNAL, 2019) DEBBARMA, SUSHANTA; ASHUTOSHThe study was conducted on buffaloes (n=12) to study the role of aquaporins in thermoregulation of buffaloes during different seasons. The relative gene expression of aquaporins in skin and upper respiratory tract were studied. For study of gene expression in upper respiratory tract, tissue samples were collected from slaughter house. In skin, AQP1, AQP3 and AQP5 expression were studied during winter, spring and summer seasons. The relative mRNA expression of AQP1, AQP3, AQP4 and AQP5 in nasal turbinate and upper tracheal mucosa during winter, spring and summer seasons were studied. The results of the study confirmed the presence of aquaporins in the studied tissue by gene expression studies and immunolocalization in the skin, nasal turbinate and tracheal mucosa. Further physiological responses, hematological parameters, electrolyte, biochemical and hormonal concentrations of the animals were evaluated to ascertain their role in the thermoregulation of buffaloes. The physiological responses viz. respiratory rate, heart rate, rectal temperature and skin temperature of buffaloes increased with increase in ambient temperature. There was a significant increase in evaporation rate from skin and pulmonary surface of buffaloes with the concomitant increase in ambient temperature during summer. The hematological components varied seasonally with PCV being lowest during summer, Hb and TEC count being highest during spring, and TLC being highest during winter. The high concentration of plasma anti diuretic hormone accompanied by low packed cell volume during summer is indicative of its role to conserve body water content in buffaloes. The higher relative expression of AQP1, AQP3 and AQP5 during summer season in skin of buffaloes along with increasing sweating rate and evaporative loss through skin is indicative of their role in thermoregulation of buffaloes. The up regulation of AQP1 in nasal turbinate during summer and the concomitant rise in pulmonary evaporation rate is suggestive of its role in water diffusion through nasal mucosa during hot ambience. The down regulation of AQP1, AQP3, AQP4 and AQP5 in tracheal mucosa during summer indicates their minor role during evaporative water loss from upper respiratory tract during summer. Different aquaporins are regulated at different levels in skin, nasal turbinate and tracheal mucosa of buffaloes during different seasons.
