Experiments have also demonstrated that cows with a BCS of 4 or lower had pregnancy rates of 61%, in contrast to 90% for those cows that calved with a BCS of 5 or greater (Selk et al. 1986).

Synthetics do not hold the oil in the brush very well and can react with the oil. A disadvantage of oil paint is that clean up must be done with a solvent such as mineral spirits. If you are allergic to solvents, it is possible to clean up with baby oil, then wash with soap and water. One good product for cleaning oil paint out of clothing is Murphy's Oil Soap. This should be used for a scrubbing the spot before laundering. One can finish an oil painting with a varnish to protect and enhance.
