Associations of soft flooring materials in free stalls with milk yield, clinical mastitis, teat lesions, and removal of dairy cows.

Discipline: housing; Keywords: thermal protection, durable lying surfaces, behaviour, free-stall lying surface softness, culling.

Is there an advantage to having soft flooring material instead of concrete? A recent Danish study investigated whether this was indeed the case; reference: L.E. Ruud, K.E. Bøe and O. Østerås. Associations of soft flooring materials in free stalls with milk yield, clinical mastitis, teat lesions, and removal of dairy cows. Journal of Dairy Science (2010) Volume 93, pages 1578-1586
Effects of twin pregnancy and dry period feeding strategy on milk production, energy balance, and metabolic profiles in dairy cows.

Discipline: lactation management; Keywords: metabolic diseases, correct feeding strategies, moderate energy, lactation length.

These questions were addressed in a study by Dr Silva-del-Rio and colleagues in a study published in 2010 in the Journal of Animal Science, Volume 88, pages 1048 to 1060. The title of the paper appropriately was Effects of twin pregnancy and dry period feeding strategy on milk production, energy balance, and metabolic profiles in dairy cows.
