Raising heifers is one of the most cost-intensive areas of the farm. From the day these animals hit the ground until they calve, they are a monetary burden on the farm. Therefore, getting these animals to calving as efficiently as possible makes sense.
During the past two decades, a reproduction revolution has occurred in the dairy industry. A consequence of increased reproductive performance has been an increase in replacement heifer inventories, which in turn have decreased replacement heifer market values. Based on the UW-Extension Dairy Replacement ICPA Survey (Akins and Hagedorn, 2015), rearing costs of Holstein heifers from birth to calving averaged $2,100 from 1999 to 2015 and exceeded $2,500 in 2015.
For nearly eighty years dairy producers have been indoctrinated in the use of the AM-PM rule for artificial insemination (AI) of cattle. The AM-PM rule dictates that a cow should receive AI 12 hours after first being observed in estrus. If a cow is seen in estrus in the AM she should receive AI that PM, and cows seen in estrus in the PM should receive AI the following AM.
Reproductive data is particularly difficult to measure which makes it a challenge to measure and monitor, even on large dairy farms. Measuring reproductive performance is about measuring probabilities—the likelihood an event will occur.
Heifers represent the future of the dairy operation, bringing genetic progress to the milking herd. Raising heifers is costly and improving efficiencies in raising them can have a financial impact on the overall profitability of the dairy business.
In 2019 Cargill conducted a Feed4Thought survey of consumers from the United States, China, Mexico, and Spain. In this survey, they asked consumers to identify the word that best described what they wanted a farmer to be. The survey showed 30% of respondents wanted farmers to be “sustainable.” The second most-used word to describe what […]
Studies to evaluate cocktail forage mixes were conducted in 2021 and supported by the UW Dairy Innovation Hub. Research discussed here includes collection of on-farm data from four farms growing a cocktail forage mix and a lactating cow feeding trial at the UW Marshfield Agricultural Research Station (ARS). Please refer to the “Cocktail Forage Mix […]
Raising replacement heifers is a large investment for farmers to create the next generation for their herd. The cost of raising a replacement heifer on average is $2,500 with feed accounting for approximately 50% of the total rearing cost.1,2 The average age at first calving (AFC) has been decreasing in the United States because farmers […]
There are three stages to the birthing process, or parturition: dilation of the cervix, delivery of the calf, and delivery of the placenta. Knowing the normal birth process will help you decide whether or not to intervene.
