waqas ahmad My listed level of rumen protected niacin is based on a California field study evaluating 3 grams vs.7 grams which resulting in lower dry matter intake. One guideline is 1 gram of rumen protected niacin is similar to 7 grams of unprotected niacin. Hope this helps! Mike

Ehsan when the session is finished the cows normally go to the bunks to rest and start rumination (not all... some cows keep eating)... after four hours an operator put the cows in the feeding line again. Have a great day!

Ehsan ... yes... I lock the cows... I call it "active standing" because during the cooling sessions the cow is standing but lose body temperature and eat TMR... the two best options during heat stress.

The sprinklers are located at around 2,00 meters from the floor (enough tall that the cows can't damage), the cows stay 1hour every session, so 6 hours per day! Every four hours (four hours is the time after cooling needed for the body temperature to rise again to the critical level)

Unfortunately, the most important thing was not mentioned, and it is intensive cooling for sufficient hours per day. Water availability, shade and preventing of cows movement will not liberate the high yielding cow from the high quantities of endogenous heat generates and so, will not prevent summr drops in performance. Only proper cooling can reach this goal!

Israel Flamenbaum it's true, I agree with you. I began to work with intensive cooling 4 years ago and the results are very good, 3-4 litres more milk and 3% more pregnancy rate compared with the previous year where the cooling system was present but not properly used. I increased the fat (by-pass) to improve the energy supply to meet the requirements (during heat stress there is vaso-contriction i ...
