Gene-Edited Dairy Goats Exhibit Enhanced Resistance to Mastitis

Sep 06, 2024

Experts from China developed gene-edited dairy goats with enhanced resistance to mastitis through a regulatory sequence gene editing breeding strategy. The results of the study are published in Advance Science.

Mastitis is a common disease affecting the livestock industry worldwide, characterized by the inflammation of the mammary gland. It is one of the leading causes of economic losses in dairy goats resulting from infection caused by pathogens, such as Staphylococcus spp. and Escherichia coli. The researchers proposed the use of gene editing to fight against inflammatory diseases using dairy goats as model animals.

"Stress can steal calories and nutrients because energy normally used for growth is redirected toward immune activation, gut repair, and other costly survival responses."
