“…Conversely, Cooke et al (2013) and Török et al (2021) indicated that Holstein cows in the UK and Hungary had significantly the longest LS when they calved for the first time early (< 26 months), compared to those calved lately (more than 28 months). While, Kalińska et al (2019) and Valchev et al (2020) reported that the Holstein cows in Poland and Bulgaria that calved for the first time at < 24 months had the shortest LS (56 and 73 months, respectively) compared to 67.2 and 88 months, respectively for those calved for the first time at >30 months. Moreover, Froidmont et al (2013) and Medina et al (2022) reported that the Holstein cows in Belgium and Honduras that calved for the first time lately at > 38 months had significantly the longest LS (81.5 and 120 months, respectively) compared to 72.3 and 73 months for those calved earlier (<30 months).…”

“…Medina et al (2022) found that the Holstein and Brown Swiss cows in Honduras that calved early at < 30 months scored the highest LMP (14290 kg and 15979 kg, respectively) compared with those calved lately (> 42 months),whereas the values were 10840 kg and 10411 kg, respectively, and the differences were significant. Kalińska et al (2019) indicated that Polish Holstein cows that calved for the first time at the age < 24 and > 28 months had significantly the lowest LMP; however, the cows that calved between 24 and 28 months produced the highest LMP.…”

“…Also, Eastham et al (2018) found that cows had AFC around 22 months produced higher LDMP (15.2 kg) than those of 36 months AFC (12.8 kg) in the UK. Kalińska et al (2019) indicated that the Polish Holstein cows that calved for the first time between 24 to 27.9 months had the highest LDMP (9.1 kg) compared to 7.8 kg for those calved for the first time at > 29.9 months.On the other hand, Salem and Hammoud (2019) indicated that the LDMP was not significantly affected by AFC in Friesian cows in Egypt.…”

This study aimed to compare the longevity and productive lifetime traits between Shami and Hol-stein cows under subtropical conditions, in addition to assess the effect of age at first calving (AFC), first lactation milk yield (FLMY), year and season of first calving on the studied traits in both breeds. The available data included 495 records for Shami and 1129 records for Holstein from birth to disposal date during the period from 1982 to 2014.The studied traits were lifespan (LS), productive life (PL), cow efficiency index (CEI), number of calvings (NC), lifetime milk production (LMP), total lactation periods (TLP), lifetime daily milk production (LDMP), and total dry periods (TDP). The least squares means of LS, PL, CEI and NC were 96.3±1.80 months, 73.2±2.80 months, 64.9±0.008 % and 4.3±0.12 calving for Shami cows in respective order. The corresponding figures for Holstein cows were 66.1±1.81 months, 43.5±2.81 months, 56.4±0.012 % and 3.5±0.19 calving, respectively. The means of LMP, TLP, LDMP and TDP were 7713±563.38 kg, 787±33.43 days, 2.7±0.13 kg and 890±25.55 days for Shami cows and 14406±875.77 kg, 1049±51.96 days, 5.9±0.20 kg and 275±39.72 days for Hol-stein, respectively.The effect of breed was highly significant (P<0.01) on all studied traits. Cows for both breeds with AFC less than 24 months had more PL and NC. Also, cows with the highest average FLMY had the highest LMP, LDMP and TLP. It could be concluded that under the subtropical condi-tions, Shami cows exhibit superiority for longevity traits compared to Holstein ones.

“…Medina et al (2020) considered that earlier age at first calving has a favorable effect of the cows, on productive life and increase in longevity. Kalinska et al (2019) constated that the dairy cows with age at first calving 791-850 days had the highest lifetime milk. Orsoletta et al (2021) constate that lower replacement rate and two years old at first calving reduce CH4 emissions.…”

The objective of this study was to estimate the genetic parameters for age at first calving in Charolais and Limousine cattle breeds using animal model. The reproduction traits are influenced by genetic factors and environmental factors. The genetic factors are breed, individual and environmental factors are: climate condition and nutrition. The data consisted on 239 records for Charolais breed and 309 records for age at the first calving for Limousine breed. The data were from Romanian Breeding Association for Beef cattle. The age at the first calving was 792.92±6.77 days for Charolais breed and 813.83±6.09 days for Limousine breed. The heritability value for age at the first calving was 0.273 for Charolais and for Limousine breed was 0.275. The breeding values of cows with records for age at first calving were between −30.697 and 40.929 for Limousine breed were between −46.64 and 42.65. For improvement the reproduction traits it is necessary to improve the environmental conditions and supervision of reproduction activity in the farms and the selection of the best cows. The selection based on the breeding values of the cows determined the improvement of age at first calving. Improvement the reproduction traits increase the profitability of farms.

Research to study the traits of duration of use and cows productive longevity of Ukrainian Black-andWhite dairy (UBWD) and Holstein breeds, depending on the age of frst calving, was carried out in the herd of PE "Burynske" Pidlisniv branch of Sumy district. The division of animals into gradations, depending on the age of frst calving, established that higher indicators of the duration and efciency of lifelong use were observed in animals of both breeds that frst calved at the age of 25.1-26 months. Early, before 24, and late, over 26 months, frst calving shortened lifetime, productive period, number of calvings, and reduced lifelong milk yield and milk fat. With an increase in the age of frst calving in UBWD and Holstein cows, a gradual reduction in lifetime and productive use reached a difference in these indicators between the best (25.1-26 months) and the frst calving group of more than 30 months, respectively 332 and 491 and 523 and 628 days (P<0.001). The inﬂuence of the age of frst calving on the lifetime productivity of cows of the UBWD breed was evidenced by a signifcant difference in favor of animals with the frst calving at 25.1-26 months, compared to the group of frst calving before 24 months, which was 3432 and 127 kg, respectively, in terms of lifetime milk yield and milk fat (P<0.001). The difference when comparing the groups of the frst calving older than 26.1 months by lifetime milk yield and milk fat was, respectively, 2082-12896 and 70-486 kg (P<0.001). The highest indicators of traits characterizing the longevity of Holstein cows, lifetime and productive use, were also obtained from the group of animals of the frst calving at the age of 25.1-26 months. According to these traits, there was a signifcant difference in their favor compared to the group of frst calving up to 24 months (282 and 173 days; P <0.05) and groups older than 26.1 months. (247-523 days; P<0.05-0.001 and 337-628 days; P<0.01-0.001). Animals of the frst calving at the age of 25.1-26 months, with a milk yield during life of 29337 kg, exceeded in this trait cows that frst calved earlier 24 months of age, with a difference in 3679 kg of milk (P <0.001) and animals with an age of frst calving older 26.1 months with a difference of 1790-12990 kg (P<0.05-0.001). By lifetime milk fat yield, the difference between these comparisons was 135 kg (P<0.001) and 56-486 kg (P<0.05-0.001), respectively. Key words: Ukrainian Black-and-White dairy, Holstein, lifespan, productive use, frst calving, lifetime productivity.
