Bacterial 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 کاملWhat 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 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 کاملInfluence of bedding material on ammonia emissions from cattle excreta.
Dairy cattle barns are a major source of NH3 emissions to the atmosphere. Previous studies have shown that the bedding material used in the barn can influence the magnitude of NH3 emissions, but little is known about which bedding characteristics are important in this respect. The aims of this study were to assess, at a laboratory scale, the relative importance of the chemical [pH, cation excha...
متن کاملRisk management of paratuberculosis in dairy herds
Risk management of paratuberculosis (Johne's disease) in a dairy herd requires an assessment of the likelihood of paratuberculosis occurring in the herd, the economic impact of paratuberculosis on the herd and an evaluation of measures that can be taken to reduce this likelihood and impact.The likelihood of paratuberculosis occurring in the herd is related to the regional herd-level prevalence ...
