The effectiveness of an automated heat detection system in Brown Swiss heifers when using sexed semen at a large dairy unit

Abstract

Identifikacija krava i junica koje se tjeraju i njihovo pravovremeno umjetno osjemenjivanje (AI) predstavljaju problem za velike mliječne farme. Cilj je ovog istraživanja bio ispitati učinak osjemenjivanja junica smeđeg goveda u estrusu uporabom sustava automatske detekcije tjeranja (AHD) u usporedbi s detekcijom tjeranja vizualnim promatranjem (VO). Primjena AHD sustava povećala je plodnost junica za 8,9 % kod uporabe konvencionalnog (neseksiranog) te za 14,4 % kod uporabe seksiranog sjemena. Broj umjetnog osjemenjivanja po začeću prilikom uporabe seksiranog sjemena spustio se s 3,7±1,08 s VO na 2,4±0,68 uporabom AHD sustava. Analiza dvaju čimbenika odstupanja pokazala je da je učinak upravljačkih odluka poput detekcije junica koje se tjeraju pomoću AHD-a i uporaba seksiranog sjemena na učinkovitost osjemenjivanja bio 89 %. Ova studija pokazala je da bi profesionalni uzgajivači i veterinari posebnu pozornost trebali posvetiti upravljanju umjetnim osjemenjivanjem u provedbi tih upravljačkih odluka na velikim mliječnim farmama.

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.
