For identification of individuals and parentage control performed by cattle breeders in the Czech Republic, a novel Finnish Bovine Genotypes™ Panel 3.1was amplified by means of one multiplex polymerase chain reaction. Bovine Panel encompasses all the 12 STR loci recommended by the International Society for Animal Genetics (ISAG) for routine use in parentage testing and identification, including...
BACKGROUND: Infectious Bovine Rhinotrachitis (IBR) caus-ed by Bovine Herpes Virus-1 (BoHV-1) was first, observed in one of the Tehran Industrial cattle breeders, with importation of cattle in 1965. Later, the isolation of bovine herpes virus approved the existence of the disease in the most of the provinces of the Iran.

The emerged installation these coincided with 3 years severe droughts (2018, 2019 2...
Sixty-four zebu cows, comprised mainly of Bunaji cattle aged between 3 and 7 years old, were involved in an intensive artificial insemination programme. The study was conducted during the breeding period (May-October), and cows were inseminated with freshly prepared Friesian semen when they stood to be mounted by the vasectomised bull or herdmates. Fertility was measured by serum progesterone (...
