Do indirect heating rather direct heating

What may be the range of usable meat pH.

Perhaps 7000 ppm is the threshold level. Since I know broiler farmers in Newzealand use CO2 setting at 7000 ppm on controllers to adjust firinimum ventilation to save expensive fuel cost in cold weather WAQAR The Automation Co Rawalpindi Pakistan

Dear Dr Czarick Dr Fairchild A new breed of fans have arrived here now manufactured and supplied by Danish and other companies based on Brushless DC (BLDC) motor and inverter ( three phase controlled ). They are much more energy efficient compared to any three phase AC fan presently available in the market. Added advantage is they are direct drive so no change of RPM over time due to worn out be ...

There have been long discussions that what would be ideal house length here in Pakistan where ,on an average,height of ceiling is eight feet and it is flat concrete unlike Europe or USA. Long lengths create pressure, due to air resistance, and reduce efficiency of fans and short lengths are in inefficient for power consumption for the same air velocity.

I thank you for your valuable comments. Appreciate how much research you have done on all aspects of ventilation and their effects on birds. Specially valuable with the advent of totally closed environmental houses where lack of perfect technical knowledge means total disaster. The poultry tips on ventilation from Georgia University are like ventilation pearls for poultry industry. We, in Pakista ...

Dear Mr Dahal You are right that not all pesticides can be rejected by RO plant but pesticides having molecular weights more than 278 are 100 percent rejected.However if one uses nano-filtration and activated charcoal upstream of the RO membran and add calcium and magnesium salts (which some fars ,here,do) and use acidification downstream will solve the major problems.However in Pakistan many fa ...

Dear Mr Dahal In your above postings you have mentioned three gadgets as point of entry. The first one and the third one are the same and are controvercial equipment( please see Wikipedia).

The syst ...

Dear Dr Fairchild & dr Czarick This scribe ,during IPE Altana expo,four years hence, saw bricks as evaporative coolers from some company in South America, who claimed it is being used there to advantage for its cheapness,easy washibility. I has the wicking property and retains the moisture for a long time due to its mass and hence can be used during wet weather without too much dropping of water ...
