Abstract

A total of 90 Assaf dairy ewes (180 half-udders) were randomly assigned to two lots: a) Treated lot with 45 ewes (90 half-udders) which received a single intramuscular dose of 200 mg β-carotene (5 ml Dalmavital®, Fatro Uriach Veterinaria, Barcelona, Spain) at 75 d postpartum, and b) Untreated lot or control lot of 45 ewes (90 half-udders). Glands were samples for SCC study at 75, 85, 95, 105, 115, 125, 135, and 150 days postpartum. Ewes treated had significantly lower SCC than untreated control ewes. Its effect was maintained from the day 10 until the day 75 post-treatment and suggested a direct or mediated effect on mammary immunity. These findings should be completed with bacteriological and cellular studies to evidence a possible immunostimulation of the ewe mammary gland.
