The aim was to determine the effect of age at first calving on longevity, lifetime number of productive days and lifetime milk yield of Holstein and Brown Swiss cows in the tropical savanna of Honduras.  The information was collected from three dairy... see more

The aim of this study was to estimate the genetic parameters for productive life in Romanian Spotted, Simmental type cattle breed using a survival model. The Weibull proportional hazard model was used in this study. The data of productive life of cattle w... see more

Adaptability of Brown breed on the plain area it is possible in conditions that provide housing and nutrition technologies concordant with morpho-physiological necessity. Advance of productive level, over 7000 kg per lactation, in accomplish condition of ... see more

The studies were carried out in 1996-2019 at the field experimental station of the Russian State Agrarian University — Moscow Timiryazev Agricultural Academy. The purpose of the research was to assess the productive longevity of various alfalfa varieties ... see more

Longevity is an important trait due to its relationship with profitability. Type traits have been used as indirect predictors for productive life. The objective of this study was to evaluate the relationship of 20 type traits on length of productive life ... see more

This study monitored survival up to fourth calving and reasons to culling of a number of 202 Holstein Friesian heifers on research farm at Agricultural Research and Development Station (ARDS) Simnic, Craiova. Heifers born between 2016 and 2019 were monito... see more
