“…In addition, cows first calving at <21 month of age have a high risk of culling due to dystocia and the high elimination is related to the quota system that exists in Canada (Nilforooshan and Edriss, 2004). Anim et al (2020) analyzed different lactations recordings and found that productive life of dairy cows gradually decrease with the increasing of the age of the first calving, especially for cows calving at an age over 29 months. Mossa and Ireland (2019) found that cows had low fertility, low milk yield, and a high elimination risk with low and high follicle numbers.…”

Dairy cow longevity is an essential economic trait that can supplement the breeding value of production traits, which is related to the herd time and lifetime milk yield of dairy cows. However, longevity is a relatively difficult trait to select for dairy cow breeding due to low heritability and numerous influence factors of the longevity in dairy cows. Longevity trait has been used as an important breeding target of a comprehensive selection index in many dairy developed countries; however, it has not been included in performance index in many developing countries. At present, cows in these countries are still in the primary stage of “large quantity, low quality, high cost, and low yield.” The average parity of dairy cows is less than 2.7, which is difficult to maintain the production efficiency to meet the demands of the dairy industry. Therefore, there is an urgent need to select and breed for the longevity of dairy cows. The various definitions and models (including linear, threshold, random regression, sire, and survival analysis) of longevity were reviewed and standardized. Survival analysis is the optimal model to evaluate longevity, and the longevity heritability is 0.01–0.30 by using different definitions and models. Additionally, the relationship between longevity and other traits was summarized, and found that longevity was regulated by multiple factors, and there were low or medium genetic correlations between them. Conformation traits, milk production traits, reproductive traits, and health traits may be used as indicators to select and breed the longevity of dairy cows. The genetic assessment methods, heritability, influencing factors, importance, breeding, and genetics of longevity were reviewed in the manuscript, which could provide a valuable reference for the selective breeding to extend the productive life of Holstein cattle.

“…The findings contradict findings ofKrogmeier et al (2015) andFuerst-Waltl et al (2019) for Fleckvieh breed. These authors revealed better traits in cows seasonally grazed Kučević et al (2020). reported similar lifetime milk yield for Holstein cows in Serbia (2% difference in favour of Holstein cows not grazed in Slovakia).…”

“…Hence, factors of farm and local conditions were found to influence age at first calving (Castillo Badilla et al, 2011;Valchev et al, 2020). Breed, housing system, herd size, herd production level and management criteria were reported to influence longevity and lifetime performance traits (Jankowska et al, 2014;Kučević et al, 2020). Moreover, grazing has been reported to have a significant effect on these traits as mentioned by Krogmeier et al (2015).…”

The objective of the study was to analyse longevity and lifetime performance traits in dependence on access to grazing (G). Data of Holstein and Slovak Spotted dairy cows (143,566 and 30,412 heads culled between 2006 and 2019) were included. Within each breed, three groups of cows were considered: (1) cows not grazed throughout their entire life, (2) cows seasonally grazed as heifers (in summer), (3) cows seasonally grazed throughout their entire life (in summer). Eight (four longevity and four lifetime milk performance) traits were analysed. General Linear Model with fixed factors: G, herd nested within G, culling year, and cow's age at first calving as covariate was applied. Cows of group (1) had the highest 305-day milk yield: 8,005.0±7.1 kg (Holstein) and 5,985.3±13.0 kg (Slovak Spotted) and lifetime milk yield: 18,408.5±59.4 kg (Holstein) and 18,237.2±129.1 kg (Slovak Spotted). Holstein cows of group (1) had the highest length of productive life (882.4±2.5 days) and number of lactations (2.37±0.01). The highest length of productive life (1,298.0±16.4 days) and number of lactations (3.46±0.04) were found in Slovak Spotted cows of group (3). The best lifetime performance (regardless of breed) was expected in cows not grazed; whereas, the best longevity traits were expected in Slovak Spotted cows seasonally grazed throughout their lives. Surprisingly, in Holstein cows, the best longevity traits were found in animals that were not grazed. This suggests that the living conditions of housed Holstein cows did not negatively affect their longevity.

Association between age at first calving and milk production in first lactation on longevity traits in Holstein cows

et al. 2020

The objective of this research was to determine the association between age at first calving (AFC) and milk production in the first lactation of longevity traits for Holstein cows. The research was conducted on 2307 cows raised on 4 farms in AP Vojvodina. The cows were culled in the period from 2017 to 2018. The cows belonged to the group of Holstein Friesian breed of cattle. Cow longevity was observed using three parameters: number of lactations (NL), lifetime milk yield (LMY) and length of productive life (LPL). The research involved the influence of the farm on which the animals realized their production, the season of first calving. A mean value obtained for the length of productive life in the analysed population was 1207 days (3.30 years on average). During this period the animals on average realized 2.45 lactations and produced on average 18798 kg milk. All studied traits showed a high level of variability. From these data, the study sought to determine the influence of factors on the traits of longevity, our research present that studied factors showed high statistical significance on these traits except in the case of the season of first calving where a statistical significance effect wasn't observed. The season of first calving did not affect the animal traits for longevity and, generally, didn't affect the calving interval. Regarding the obtained correlation data between age at first calving and length of productive life, it can be concluded that belated AFC leads to reduced reproductive performance.
