The 36th Meeting of Dairy Club (Joint Venture of Alltech and UVAS) was held on Monday June 16, 2014 at Syndicate Room UVAS. Following was the agenda of meeting:

Minutes of meetings are as follows:

Dr. Muhammad Zafar Ullah Khan opened the house and gave warm welcome to the participants. He introduced the worthy speaker and explained the agenda.

Speaker Prof. Dr. Muhammad Abdullah

Managing Heat Stress by Prof. Dr Abdullah

Prof. Dr. Muhammad Adullah delivered lecture on “Heat Stress Management in Indigenous dairy Animals”. During his lecture he discussed:

• Cow comfort is the basics for profitability:
• Physical
• Nutritional
• Social
• Thermal

• Bos taurus  vs. Bos Indicus
• Genetic Control of Heat Stress
• Major Climatic Components
• Air temperature,
• Humidity,
• Solar radiation,
• Wind velocity and
• Precipitation produce a combined effect on the ‘thermal comfort’ of the animals and their performance.

Thermoneutral Zone

• Sources of Heat
• Environmental Temperature
• Metabolic Heat
• Heat of radiation (direct/Indirect)
• Mechanisms of heat exchange
• Conduction: Heat moves from warmer to cooler surface through direct contact.
• Convection: The layer of air next to the skin is replaced with cooler air.
• Radiation: Heat can radiate from a warmer environment to a cooler environment.
• Evaporation: Moisture evaporates from the skin (sweating) and lungs (panting).
• Temperature Humidity Index (THI)
• Signs of Heat Stress
• body temperatures rises > 102.6 ◦F 
• Panting>80 breaths per minutes
• Reduced activity
• Increased water intake
• Seek shade
• Reduced feed intake (>10-15%)
• Reduced milk yield (10 to 20% or more)
• Factors Which Determine Severity Of Heat Stress
• Actual temperature and humidity
• Length of the heat stress period
• Degree of cooling that occurs at night
• Ventilation and air flow
• Cow factors (size, milk production)
• Housing type , ventilation
• Breed
• Water availability
• Hair coat  colour and depth
• Heat Stress in Buffalo
• Buffaloes exhibit signs of great distress when exposed to direct solar radiation during hot weather
• Buffalo bodies absorb a great deal of solar radiation because of their dark skin and sparse coat or hair
• In addition buffalo possess a less efficient evaporative cooling system due to their poor sweating ability
• Approaches to Minimize the Effects of Heat Stress
• Two basic approaches -                 
• a. Housing and facility management
• b. Feeding management

Presentation was beautified with pictorial description which opened a long discussion among audiences. 

Presentation 2: Punch the Heat Stress…The Secret Recipe

Dr. Asad Mehmood presented on how Yea-sacc can be an effective tool to minimize the effect of heat stress and earn profit.

–        Yea-sacc 1026 increases Feed intake, Milk production, Feed efficiency and milk components

Yea-sacc = Profit

Farm size: 500 animals  X 106.43 per day =  Rs 53,215/day

Cake Cutting Ceremony of Dairy Club 3rd Anniversary

Dr. Ilyas paid thanks to the speakers and called guests for cake cutting ceremony.

Many thanks to all for their time and contributions throughout all those years passed to Dairy Club since
