- Abstract
Many studies have been conducted to estimate climate change on dairy production and reproductive efficiency, dairy production vulnerable to climate change and heat stress which impact the milk production of reproductive performance , this research aim to investigate the impact of climate change on production and reproductive efficiency of the Holstein cows. The most important results were: The Holstein caws vulnerable to heat stress in the three regions for all seasons except winter. The increase in THI in Gharbia Governorate for summer was more than each of winter, spring an autumn by about 18.55, 12.04, 5.91 degrees, consequently. The increase in THI by 1% leads to increase by 1.78, 1.25, 0.94 and 1.32 % for foot and moth disease, mastitis, pneumonia and smallpox consequently. Using the means of mitigating the THI leads to increase the cost production. The losses of milk production resulting of high THI estimated by about 457.7 Kg, (annul) for the head from the foreign cow. Mitigating the effect of THI leads to improve the milk production high revenue. Recommendations: Inform the farmer by the dangerous of climate change and its impact of the animal specially the diary and used the means mitigating its effect. Raising awareness of farmers on usage of means that restrict effect of climate change, like making umbrellas, using ventilation methods and avoiding leaving animals in direct sunlight. Necessity of making heredity improvements that produces breeds able to endure climate changes and adapt to it.
