Autor: Roswitha Baumung, Maria Wurzinger, AM Okeyo, D. K. Semambo, Johann Sölkner, D. Ndumu, Adam G. Drucker

Publikováno v: Livestock Science. 113:234-242

Ankole cattle are well known for their massive white horns and red coat colour. These characteristics are attributed to centuries of cultural breeding practices. Two experiments with traditional cattle keepers were carried out at a governmental Ankol

Publikováno v: Tropical Animal Health and Production. 38:571-581

A survey in Burundi, Rwanda, Tanzania and Uganda was conducted in order to determine the different production systems under which Ankole cattle are currently kept. Additionally, selection criteria of livestock keepers were documented. In Burundi, Rwa

Ultrasonographic study of early embryonic loss induced by Actinomyces pyogenes in cattle

Autor: SN Omran, D K Semambo, JS Boyd, D J Taylor, TR Ayliffe

Publikováno v: Veterinary Record. 131:7-12

Four cows were inoculated into the uterus with Actinomyces pyogenes between 30 and 41 days of gestation. Gross morphological changes were monitored by rectal palpation and with a realtime B-mode two-dimensional scanner with a 7.5 MHz transrectal line

Pregnancy-specific protein B and progesterone in monitoring viability of the embryo in early pregnancy in the cow after experimental infection with Actinomyces pyogenes

Autor: D K, Semambo, P D, Eckersall, R G, Sasser, T R, Ayliffe

Publikováno v: Theriogenology. 37(3)

Actinomyces pyogenes can cause embryonic death and abortion during the early stages of pregnancy in cows. Bovine pregnancy-specific protein B (PSPB) is produced in response to a viable embryo and as such it could be a potential marker for embryronic

Early abortion in cattle induced by experimental intrauterine infection with pure cultures of Actinomyces pyogenes

Autor: TR Ayliffe, JS Boyd, D K Semambo, D J Taylor

Publikováno v: The Veterinary record. 129(1)

Actinomyces pyogenes from a case of endometritis was used to study the effects of infection of the bovine embryo between days 27 and 41 of pregnancy. From 10(9) to 10(10) washed organisms were introduced into the uterine lumen of four pregnant cows.
