ORIGINAL_ARTICLE Since there is not enough data about milkability of the Jersey cows, the aim of this paper is to show basic milkability traits of this cattle breed depending on the parity and milk flow curve types. Cows had average daily production (DMY) of 22.23 kg, milk yield per milking (MYM) of 9.72 kg, and average and maximum milk flow about 1.66 and 2.49 kg/min, respectively. Statistical analysis showed that DMY and MYM of the cows in 4th parity was significantly (p < 0.05) higher comparing to cows in 1st and 3th parity. The duration of entirely milking is similar regarding the paritiesand only the cows in 3th and 4th differ significantly (p < 0.05). Regarding the effect of milk flow curve, the significant (p < 0.05) difference between unspecified and rectangular milk flow curve has been found for the average milk flow (AMF) and descending phase of the milk flow curve (TD). Cows with unspecified milk flow curve, have significantly (p < 0.05) lower AMF and longer TD compared to cows with rectangular curve. Cows with bimodal milk flow curve have significantly (p < 0.05) longer duration of the ascending phase compering to: unspecified, descending and rectangular. The results of this study have shown that Jersey cows have lower production and milk flow compared to other dairy cattle breeds. Nonetheless, they have uniform milkability traits, and a large representation of desirable milk flow curves which are associated with a beneficial effect on the udder health. https://macvetrev.mk/Files/Article/2020/10.2478/macvetrev-2019-0026/macvetrev-2019-0026.pdf 2020-03-15T09:00:00 5 12 10.2478/macvetrev-2019-0026 Jersey cows milkability parity milk flow curve types Tina Bobić false 1 Department for Animal Production and Biotechnology, Faculty of Agrobiotechnology Science Osijek, University of Josip Juraj Strossmayer in Osijek, Vladimira Preloga 1, 31000 Osijek, Croatia AUTHOR Pero Mijić false 2 Department for Animal Production and Biotechnology, Faculty of Agrobiotechnology Science Osijek, University of Josip Juraj Strossmayer in Osijek, Vladimira Preloga 1, 31000 Osijek, Croatia AUTHOR Vesna Gantner vgantner@fazos.hr false 3 Department for Animal Production and Biotechnology, Faculty of Agrobiotechnology Science Osijek, University of Josip Juraj Strossmayer in Osijek, Vladimira Preloga 1, 31000 Osijek, Croatia LEAD_AUTHOR Gjoko Bunevski false 4 Faculty of Agricultural Sciences and Food, Ss.
