Yes! Really?? This is often the answer I receive when I speak about feeding dairy calves once per day. Or some are confused by feeding calves once a day. You probably think I am crazy, but let me tell you a little about how and why you can group feed calves once per day. Feeding group fed dairy calves once a day is very popular in New Zealand and other parts of the world where grazing dairy cattle is the norm. In Ireland, research has shown that calves can be fed successfully once per day, and the system utilizes less labor and may promote earlier weaning. However, because of the earlier weaning, calves may eat more grain.

Dairy replacement feeding and management systems have undergone major evolution in the last 25 to 30 years. As herd sizes increased, individual hutches were introduced to protect calves from contaminated and overcrowded environments. Recently, higher levels of milk feeding are recommended to promote early growth, and now some farmers are adopting extended suckling until calves are weaned. Group calf rearing offers opportunities to reduce labor and to aid in socializing calves, but performance of group managed calves in enlarged hutches is not well documented.

Maintaining the health and growth of dairy calves is very important in their first few months of life. For the University of Minnesota's organic dairy, no organic milk replacers are available, so whole milk from high somatic cell organic cows as well as bulk tank milk must be fed. By using whole milk, the casein in milk will clot and provide nutrition throughout the day for calves fed once per day. We have an on-going research study at our organic dairy to evaluate the growth, health and, most importantly, the economic performance of dairy calves fed once per day and weaned at different ages.

During the spring of 2011, we evaluated group fed calves as part of a 2-year study. Calves were born from March to June 2011, and breed groups of calves were Holsteins (contemporary and 1964 genetics); crossbreds that including combinations of Holstein, Montbeliarde and Swedish Red for high-input confinement dairying, and crossbreds that included Holstein, Jersey, Swedish Red and Normande for low-input dairying. Calves were fed in groups of ten, and groups were fed 1.5% of birth weight of 13% total solids organic milk once daily and weaned when the group consumption averaged 2.0 lb of starter per calf per day. Calves were consuming about 11.5% of their birth weight in whole milk once a day. The average daily gain (lb) for breed groups was: Holstein (1.59), 1964 Holstein (1.34), High-input crossbreds (1.49), and Low-input crossbreds (1.32). From our preliminary results, adequate gain can be achieved in calves that were group fed once a day. Successful group feeding of organic dairy calves is enhanced with aggressive suckling during infancy and early consumption of high quality organic calf starter.

There are advantages and challenges of feeding calves once per day in a group feeding system.

Advantages are:
