Other claims from this paper (13)
- Intervention effect Formaldehyde applied at ensiling restricted silage fermentation, with the effect increasing with level of application.
- Intervention effect Formaldehyde treatment reduced protein degradation in the red clover silages.
- Observation Recovery of applied formaldehyde in the silages was low, below 13%.
- Association Recovery of applied formaldehyde in the silages increased with level of application.
- Intervention effect Formaldehyde at high levels of application had a deleterious effect on intake, live-weight gain and feed conversion ratio, which followed quadratic trends.
- Intervention effect Urea supplementation tended to increase intake and live-weight gain at formaldehyde levels above 34 g/kg CP.
- Intervention effect Urea supplementation did not affect N retention.
- Intervention effect Formaldehyde reduced apparent digestibility of dry matter, organic matter, N and energy with increasing level of application.
- Intervention effect Formaldehyde had no effect on cellulose digestibility.
- Association Butyric acid and 2, 3-butanediol content increased at intermediate levels of formaldehyde application.
- Observation N balance data indicated poor utilization of the supplementary urea N.
- Recommendation The data show little advantage for formaldehyde over a formic acid control, and serious disadvantages when large quantities are applied.
- Mechanism The supply of rumen-degradable N was not the major limiting factor on these diets, suggesting that formaldehyde effects were not rescued by urea.
