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...

Resistance to airflow through bedding materials used in infancy.

Various bedding materials used in infancy, including duvets (or continental quilts), were tested for airflow using the British Standards Institution tests for pillows or fabrics. Resistance was also measured when the items were placed on a dummy infant face. Measurements were made on washed and unwashed garments, which were tested both dry and wet. Results suggest that all the bedding materials...

Fertility of semen used in commercial production and the impact of sperm numbers and bacterial counts.

The objective was to monitor sperm counts and bacterial presence on randomly pooled semen doses over 3y and to determine effects on the farrowing rate and total born in two large farm systems, each serviced by their own boar stud. Sperm counts were divided into increments of 0.5x10(9) for data analysis. There was no effect of sperm count or the presence of bacteria on farrowing rate (n=9502 obs...
