Major Research Accomplishments

• Work performance of lactating non pregnant, dry non pregnant cows and buffaloes, indigenous and crossbred male bullocks were carried out during ploughing and carting. Animals were monitored for different hormones during work and rest.
 
• Cutaneous skin blood flow in cattle and buffaloes were monitored during treadmill exercise during summer and winter season. Blood flow to periphery increased significantly due to treadmill exercise compared to resting conditions.
 
• On the basis of gradient of change in physiological responses, skin temperature and milk productivity, it was observed that the minimum variations took place between 15-25°C in KF and Murrah buffaloes and 15-28°C in Sahiwal cattle.
 
• The total immunoglobulin (Ig) levels were found to be higher during winter than summer season in Karan Fries cows. The level of total Ig was significantly lower (P<0.01) in mastitic and wounded animals on the day of detection compared to after treatment during both the seasons.
 
• The productivity of animals was related to climate change in terms of ambient dry bulb, maximum temperature and Temperature Humidity Index. The milk production decline in Zebu and crossbred cows and buffaloes with increase in temperature humidity index.
 
• Expression profile of major heat shock protein genes during different seasons in cattle and Murrah buffaloes under tropical climatic conditions     were carried out.
 
• Adaptative genetic and physiological changes in integument, fibroblast cells and melanocytes of cattle during different seasons were carried out.
 
• Seasonal variation in metabolic activity and related gene were studied in Tharparkar and Karan Fries heifers
 
• Poor quality of semen and their amelioration by supplementing astaxanthin (potent herbal antioxidant) to Karan Fries breeding bulls during summer stress.
 
• Insight into thermal adaptations of Tharparkar and Karan Fries cattle through thermal imaging during summer season were studied.
 
• Mitigation of heat stress using custom design shelter system and supplementation of chromium propionate to growing Karan Fries cattle.
 
• Influence of astaxanthin supplementation on growth performance, immunity and antioxidant status of Karan Fries heifers during summer season.
 
• Effect of melatonin implant on productive and reproductive performance of Murrah buffaloes were carried out during summer season
 
• Effect of astaxanthin and prill fat supplementation on energy metabolites, stress markers and milk production in rural buffaloes during summer season.
 
• Effect of betaine supplementation on growth performance, feed intake and stress biomarkers status of buffalo heifers.

Guidance to student:

• M.Sc/ M.V.Sc : 16
 
• Ph.D. : 05

Awards:

Patents, Technology, Methodology, Genetic Stock, Variety, etc.:

• Demarcation of the ranges of ambient temperature (thermoneutral zones) for Indian cattle, Zebu crosses (Karan Fries and Karan Swiss) and buffaloes.
 
• Developed methodology for alleviating thermal heat using fan cum mist system. Angular high velocity blasting fan were used for effective heat dissipation and sustaining milk production and improving feed intake in crossbred cows and buffaloes during hot dry and hot humid months.
 
• Developed work performance indices for Haryana and crossbred bullocks during carting based on Oxygen /pulse/kg body weight.
 
• Developed a map to demarcate the different zones of India for stress and comfort based on temperature humidity index (THI).
 
• Developed a methodology to monitor methane emission in ruminants.
