In order for dairy producers to comply with animal welfare recommendations, financial investments may be required. In Canada, a new dairy animal care assessment program is currently being implemented under the proAction Initiative to determine the extent to which certain aspects of the Code of Practice are being followed and to assess the care and well-being of dairy cattle on farm. The aim of the current study was to evaluate the association between meeting the proAction animal-based and the electric trainer placement criteria and certain aspects of productivity and profitability on tiestall dairy farms. The results of a previous on-farm cow comfort assessment conducted on 100 Canadian tiestall farms were used to simulate the results of a part of the proAction Animal Care assessment on these farms. Each farm's productivity and profitability data were retrieved from the regional dairy herd improvement associations. Univariable and multivariable linear regressions were used to evaluate the associations between meeting these proAction criteria and the farms' average yearly: corrected milk production, somatic cell count (SCC), calving interval, number of breedings/cow, culling rate, prevalence of cows in third or higher lactation, and margins per cow and per kilogram of quota calculated over replacement costs. The association between milk production and the proAction lameness criterion was moderated through an interaction with the milk production genetic index which resulted in an increase in milk production per year with increasing genetic index that was steeper in farms that met the proAction lameness criterion compared with farms that did not. Meeting the proAction body condition score criterion was associated with reduced SCC and meeting the proAction electric trainer placement criterion was associated with SCC through an interaction with the farms' average SCC genetic index. The increase in SCC with increasing SCC genetic index was milder in farms that met this criterion compared with farms that did not. Farms that met the proAction electric trainer placement criterion had 4.6% more cows in their third or greater lactation. These results suggest that some associations exist between the productivity of Canadian tiestall farms and meeting several parameters of the proAction Animal Care assessment. Meeting these criteria is unlikely to impose any economic burden to the dairy industry as a whole.

为了使乳制品生产商遵守动物福利建议，可能需要进行财务投资。在加拿大，目前在proAction倡议下正在实施一项新的奶牛动物护理评估计划，以确定在多大程度上遵守《行为守则》的某些方面，并评估农场奶牛的护理和福祉。当前研究的目的是评估满足基于动物的proAction和电动培训师的放置标准以及在Tiestall奶牛场的某些方面的生产率和盈利能力之间的关联。先前对100个加拿大铁栏农场进行的农场母牛舒适度评估的结果用于模拟对这些农场进行的ProAction Animal Care评估的一部分结果。每个农场 从区域奶牛种群改良协会获取了生产力和获利能力数据。使用单变量和多变量线性回归来评估满足这些proAction标准与农场平均每年之间的关联：校正的牛奶产量，体细胞计数（SCC），产犊间隔，种/牛数，淘汰率，奶牛患病率第三或更高的泌乳量，每头母牛和每公斤定额的利润（按重置成本计算）。牛奶产量与proAction me足度标准之间的关联通过与牛奶产量遗传指数的相互作用而得以缓和，这导致每年的牛奶产量增加，而与proAction me足度标准相比，满足proAction me足度标准的农场的遗传指数增加了。没有。通过与农场平均SCC遗传指数的相互作用，满足proAction身体状况评分标准可以降低SCC，满足proAction电动教练位置标准可以与SCC相关。与不符合标准的农场相比，符合该标准的农场的SCC随SCC遗传指数的增加而增加。符合proAction电动教练安置标准的农场在第三次或更多次泌乳中的母牛增加了4.6％。这些结果表明，在加拿大的梯田农场的生产力与满足proAction Animal Care评估的几个参数之间存在某些关联。满足这些标准不太可能给整个乳制品行业带来任何经济负担。
