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 persistency measure's connection with the 305-day milk output is a crucial feature (Strapáková et al, 2016). High-persistence cows could experience more stress during lactation, which might hurt reproduction or longevity (Mostert et al, 2008).…”

Milk persistence in dairy cows is an economically important trait that will determine profit for the dairy industry and will help to overcome immeasurable diseases in dairy. cows. This study looked at the best breed that will maintain persistency for a certain time and ranked the animals based on milk yield and persistency. The study used a total of 60 nursing cows, 20 Sokoto Gudali, 20 White Fulani, and 20 Red Bororo were used for the daily milk collection. The total milk collected in a week was added together and divided by seven days to get the average daily milk yield for each breed (Sokoto Gudali, White Fulani and Red Bororo). The duration of the milking periods was recorded in days. Persistency of milk yield was computed by the ratio of the lactation period and divided into four equal periods of 30 days each. The total 30-day milk yield of each period per cow was calculated. Data collected were analyzed using the general Linear Model of the SAS program while significant means were separated using the Duncan Multiple Range Test. The results revealed that the Sokoto Gudali cows yielded significantly (P < 0.05) higher daily milk (4.13 - 4.31 L/day) whereas Red Bororo (0.72 - 0.94 L/day) was lowest in week 1. At week two, Sokoto Gudali (4.09 - 4.31 L/day) had the highest milk whereas Red Bororo (0.82 - 1.04 L/day) was the least. At week three, Sokoto Gudali (4.19 - 4.39 L/day) had a significantly (P < 0.05) higher daily milk whereas Red Bororo (0.74 - 0.90 L/day). In week 4 same trends were also observed. Sokoto Gudali (4.19) was ranked to be superior (1), followed by the White Fulani (1.62) with the breed (2) whereas the Red Bororo (0.89) was the least (3) in terms of total milk yield. The average weekly milk yield persistency showed that Sokoto Gudali and the Red Bororo breeds were maintained at high persistency from week one through week four without a significant decline. Breeds influenced daily milk yield from week 1 to week 4. The overall ranking of breeds on milk yield revealed that Sokoto Gudali was ranked the highest followed by White Fulani and the least was Red Bororo.

This article accelerates the development of selection methods for selecting the best genotypes that are acceptable from the similarity genotypes of imported Holstein cattle typical of Chinese, German and Slovenian selection. The genetic potential of reproduction and productivity of breeding breeds in genotype-environment interactions has been demonstrated. The results of the same feeding, storage and performance of Holstein cows in summer and winter, the productivity characteristics of the cattle are presented.
