Impact Change Climate on the Milk Production in the Dairy Goats

Background: Milk production is considered one of the main pillars in building the livestock sector. When faced with one of the challenges, such as summer heat stress, which may change its course to the deterioration of milk backwards, reduce production and decrease the efficiency and quality of milk, so it was urgent to draw attention to investigated the related between environmental parameters and the milk production of hot season and milking season (spring and summer) period. The goal of recently study investigated effect heat stress on milk production in the dairy goat's data set (2017- 2018) containing 65 Saanen, 73Alpin and 22 Boer (in the age of 1-2 year). Result: Milk analysis recorded daily maximum and minimum temperature- humidity index. Generally THI was 70.1, 82.7 in the spring and summer. General the average daily milk production was 0.7, 1.1, 0.7 for Alpine, Saanen and Boer respectively during spring and 0.9, 1.6, 0.7 for Apline, Saanen and Boer consequently during summer. Conclusion: In small ruminant (dairy goat) change in climate as increase ambient temperature caused heat stress and negatively effect on the milk production.
