What have we learned about using recycled manure solids for bedding?
Organic bedding sources are becoming more expensive and difficult to find. Sand can be considered the ideal bedding source for dairy cows; however, not all producers consider sand a feasible alternative for their operation. Inherent properties of sand can make it difficult to handle in some manure systems. Large amounts of bedding can be obtained from mechanical liquidsolid separation of manure...
متن کاملBacterial counts on teat skin and in new sand, recycled sand, and recycled manure solids used as bedding in freestalls.
On modern dairy farms, environmental mastitis pathogens are usually the predominant cause of mastitis, and bedding often serves as a point of exposure to these organisms. The objective of this longitudinal study was to determine bacterial populations of 4 different bedding types [deep-bedded new sand (NES), deep-bedded recycled sand (RS), deep-bedded manure solids (DBMS), and shallow-bedded man...
متن کاملFactors Affecting Manure Output on Dairy Farms
The amount of manure produced on dairy farms can affect the financial bottom line. Labor, equipment, and facilities are needed to move and store manure, all of which have a cost. Increased output of manure can represent losses in potentially digestible nutrients (increased feed costs). Lastly, the environmental impact of dairy farming is strongly related with the quantity and composition of man...
متن کاملComparison of bacteria populations in clean and recycled sand used for bedding in dairy facilities.
Bedding samples were collected twice from commercial dairy free-stall facilities that used recycled sand and clean sand in both the summer and winter. Collection began on the day sand was taken from the pile (d 0) and placed in the free stalls, and continued for 5 to 7 additional days. The number of colonies per gram of bedding of gram-negative bacteria, coliforms, Streptococcus spp., and Klebs...
متن کاملManure collection and distribution on Wisconsin dairy farms.
Manure management plans require knowing the amount of manure produced, collected, and available for land-spreading. Whereas much information is available to calculate manure production, little is known about the types and amounts of manure actually collected on typical dairy farms. This study of 54 representative Wisconsin dairy farms showed significant regional, housing, and herd size differen...
