Abstract
The study aimed to examine the analyses of the trend in the numbers of dairy cows, production and reproductive traits in the population the Slovak Spotted cattle for period 2010 to 2019. The number of Slovak Spotted dairy cows is maintained on a relatively stable level in recent years. There was a decrease in the number of animals (12 428 in 2010), but not as strong as after 1990 (85 518). From 2017 number of animals is rising from 14,062, to 14,150 (2018) and 14,627 (2019), respectively. As compared to 2010 an increase of 13.15% in 2017, 13.86% and 17.68%, in 2018 and 2019 respectively was observed. Population size raised from 113.15% (2017) to 117.68% in 2019 respectively. The average annual increase in milk production between the years 2010 to 2019 was + 157.5 kg of milk (total 1,575 kg of milk), + 5.8 kg of fat (total 58 kg of fat) and + 6.1 kg of protein (total 61 kg of protein). Positive growth of milk production in recent years is slightly comparable with the trend of breeding improvement.
Highlights
The cattle are considered to have been one of the first domesticated animals by man for agricultural purposes before 10, 000 years as shown by different authors
2.2 Coding of breeding type Cows were divided according to the Herd Book classification to subsequent breed-type groups: S0 – purebred Slovak Spotted with the proportion of foreign breeds less than 12.5%; S1 – cows with the genetic proportion of Slovak Spotted from 75% to 87.4%; S2 – cows with the genetic proportion of Slovak Spotted from 50% to 74.9% (Bujko et al, 2019; Slovak Simmental Breeders Association, 2020)
3 Results and discussion The number of dairy cows decreased by 13.46% between the years 2010 to 2019 in the Slovak Republic
Summary
The cattle are considered to have been one of the first domesticated animals by man for agricultural purposes before 10, 000 years as shown by different authors. Simmental cattle is the second most important breed in Europe, following the group of Holstein Friesian cattle and holsteinized populations (Perišić et al, 2009; Strapák et al, 2013; Doublet et al, 2019). These cattle are originated from Switzerland, but it has spread around the world. Simmental name is derived from the place of origin-the valley Simme Nowadays, it is enhanced in all continents, and its population is represented by 41 million animals. It is enhanced in all continents, and its population is represented by 41 million animals It is one of the biggest worlds cattle populations (Strapák et al, 2013; Cziszter et al, 2017; Zółkiewski et al, 2018). It is mainly due to its excellent dairy as well as beef production (Strapák, 2004; Bujko et al, 2011; Strapák et al, 2013; Kasarda et al, 2015; Kadlečík et al, 2017), and belongs to the Simmental type of cattle
