In a survey that we carried out recently in Israel, we found a great variation between farms, in terms of the number of hours along the day the cows are in "heat stress" condition (body temperature above normal). This variation is correlated with cow’s milk yield and breeding performance during summer months. As time in a day, cows face heat stress is longer, the drop in milk production and ...

The summer heat stress is one of the largest causes of economic losses to dairy farms in the world. In particularly hot regions, a drop of more than 1,500 liters par lactation from cow’s potential is reported, with a loss in potential annual net income of about $ 600 per cow. Optimizing cow cooling can reduce the annual production loss to less than 200 liters, and the financial loss to almos ...

Efficient cooling systems based on water evaporation from cow's body surface have been developed in last four decades in dairy sectors of warm climate countries. The main effect of cooling is in reducing the drop in food consumption caused by heat stress, in addition to the normal drop in food consumption in the beginning of lactation, resulted by the mobilization of body reserves and with all its ...

Summer losses in milk production are usually related to the negative impact of summer heat stress on the lactating cow. In the last 40 years, some studies realized in different parts of the world showed that also dry cows are negatively affected, when subjected to heat stress conditions. These losses are mainly related to lower milk volume and solids production, as well as fertility traits in earl ...

waqas ahmad Dear SirThanks for your commentsI do not enter into other factors out of the cooling process, which is the field of my expertise. I leave the others to other experts in case they are interested in contributing to this discussion.

Achieving high conception rate is one of the conditions for achieving efficient production of milk at farm level. For many years the Israeli dairy industry suffered, like other farms in warm countries, a significant decline in the ability to pregnant the cows during summer months, causing reduction in the efficiency of milk production and seasonality in milk supply to the industry and market. Unl ...

Dairy sectors all over the world have been using the cattle heat load index (THI) as a mean of characterizing the climatic conditions to which cows are exposed. This is true when analyzing the results of experiments and surveys, as well as the routine by which milk producers operate their farms. The heat load index is based on a formula that includes the ambient temperature and relative humidity ...

Rafael Angel Paredes this is another issue, Rafael! The evaluation we make is on a certain type of cow and in this case, Holstein cows in high productive level weighting 600-700 kg.

Ehsan Theoretically, the preferred ratio for all parameters studies is 1.0 To my opinion, being realistic, a ratio of above 0.9 for PR (which is different from CR), will be considered as good !
