Gunay A., U. Gunay: Effects of Clinical Mastitis on Reproductive Performance in Holstein Cows. Acta Vet. Brno 2008, 77: 555-560.The objective of this study was to determine the effects of clinical mastitis on reproductive performance in 135 early lactation cows. The animals were divided into two groups according to the occurrence of mastitis as follows: group I (n = 45), clinical mastitis prior to the first artificial insemination breeding; group II (n = 45), clinical mastitis after artificial insemination and being diagnosed pregnant. Forty-five cows without any mastitis served as control group.Calving to first service intervals were significantly longer (P < 0.05) in cows with clinical mastitis before first service (group I; 95.2 ± 5.4 d) than in cows with clinical mastitis after first service (group II; 77.4 ± 8.2 d) and in control cows (75.9 ± 6.3 d). Calving to conception interval with clinical mastitis before first service (119
The importance of Rubella IgG determination in Turkish pregnant women is discussed and recommendations for prevention and control of congenital rubella syndrome (CRS) are suggested.
In order to use DFA as a more reliable and rapid diagnostic test of C. trachomatis in female genital infection, false-negativity must be eliminated. Specimens must be collected adequately and concentrated in order to achieve optimal diagnostic success.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
