ABSTRACT
AL-Moosawi ZH, AL-Qayim MA, Effect
of parity, lactation and breed on milk lactoferrin
and immunoglobulin A levels in ewes, Onl J Vet Res.,
25 (3): 245-251, 2021. Lactoferrin
and immunoglobulins in milk can affect offspring immunity, health, growth,
performance and intestinal microbiota. We determined lactoferrin
and immunoglobulin A by ELISA in milk of 20 Awassi
and 20 karakul late pregnancy ewes for 60 days of lactation and partus. In Awasi ewes, mean lactoferrin in colostrum was 27.26 and milk 13.79μg/ml at 30 days and 12.28μg/ml
at 60 days whereas in Karakul ewes were 15.54, 12.09 and
10.58 μg/ml, respectively (P < 0.05). Lactoferrin in colostrum was higher than milk declinining 48-54 % in Awassi and
18-31% in karakul ewes by 60 days. Increased parity was associated with reduced
lactoferrin in colostrum in both breeds. We found no
differences in milk immunoglobulin A levels in
colostrum but in milk by days 30 and 60 declined 32-40% in Awassi
ewes but only 18 to 24% in Karakul ewes (P < 0.05). We found positive
correlation between milk lactoferrin and immunoglobulin
A in Awassi R2=0.958,
and Karakul ewes R2=0.924.
