The identification of cows and heifers in heat and their timely artificial insemination (AI) is an important issue for large dairy units. The objective of the research was to study the efficiency of insemination of oestrous Brown Swiss heifers using am automated heat detection system (AHD) compared to heat detection by visual observation (VO). The AHD system application increased the fertility of heifers by 8.9% when using conventional semen (unsexed) and by 14.4% using sexed semen. The number of services per conception when using sexed semen decreased from 3.7±1.08 with VO to 2.4±0.68 with AHD. Two-factor analysis of variance showed that an 89% effect of managerial decisions such as the detection of heifers in heat by means of AHD and the use of sexed semen on the efficiency of insemination. This study showed that professional breeders and veterinarians should pay particular attention to AI management when making these managerial decisions in large dairy units.
期刊介绍：
The goal of the journal is to provide an international platform for the publication of articles in the fields of veterinary and animal sciences, and biotechnology. The content of the journal is particularly dedicated to veterinary practitioners, but also to veterinary scientists and university professors, to encourage them to share their knowledge and experience on this platform. Manuscripts submitted to the journal may include: original scientific papers, review articles, short communications, professional articles, case reports, conference reports and literary records and reviews of new book either in Croatian or English languages.
