The digestion by cattle of grass silages made with no additive or with the application of formic acid or formic acid and formaldehyde. Rooke, J. A.; Greife, H. A.; Armstrong, D. G. (Dep. Agric. Biochem. Nutr., Univ. Newcastle upon Tyne, Newcastle upon Tyne, UK). Grass Forage Sci., 38(4), 301-10 (English) 1983. CODEN: GFSCDW. ISSN: 0142-5242. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) Section cross-reference(s): 17 The aim of the expt. was to assess the effect of applying at com. recommended rates, formic acid [64-18-6] or formic acid/formaldehyde [50-00-0] at ensilage upon the subsequent digestion of the silages by cattle. Three wilted grass silages were made from perennial ryegrass ensiled dry at a dry matter (dM) concn. of 206 g/kg after a poor wilting period of 49 h without additive application and with application of 2.5 L/ton of formic acid or of 4.5 L/ton of a mixt. of (g/kg) 500 formic acid, 200 H2SO4, and 200 formalin giving an application rate of 15 g formaldehyde/kg herbage crude protein (N ′ 6.25). The silages were fed to cattle equipped with rumen cannulae and duodenal re-entrant cannulae. Results from analyses of silage compn. and from the digestion of org.In this experiment, several chemicals are used like 64-18-6 and 50-00-0 matter and N showed no major difference between silages. The efficiency of rumen microbial N synthesis, the rumen degradability of silage N (detd. in vivo or in sacco), and in vivo digestion of individual amino acids were also unaffected by additive treatment. These results indicate that poor wilting conditions before ensilage restricted the effectiveness of additive treatment; the ineffectiveness of formaldehyde in reducing the rumen degradability of silage N may also have been related to the low rate of formaldehyde application. .
