“…The concentrations of acetic, propionic, and n-butyric acids in the untreated silages in both experiments are within the normal range for silages made from a variety of swards (McLeod et al 1970;Gordon et al 1961;Bryant and Lancaster 1970;Castle and Watson 1970).…”

“…Recent work has shown that the voluntary consumption of silage is negatively correlated with the concentrations of volatile fatty acids (VFA) and ammonia in the dry matter (Gordon et al 1961;Jackson and Forbes 1970;Wilkins et al 1971;Brown and Radcliffe 1972). Hence, the addition of chemicals which would decrease the concentrations of VFA's and ammonia in silage could be expected to be of value for increasing voluntary intake.…”

Two experiments were conducted in which solutions of formaldehyde (HCHO) were applied to clover-dominant herbage before conservation as high-moisture silage.In Experiment 1 the HCHO application rates were 0, 0.6, 1.1. 2.2, and 4.4% (wjw of the dry matter treated), and 15 kg quantities of the herbage were ensiled in small polythene containers. Rates of HCHO up to 2.2% decreased the content of acetic acid, increased the content of a compound identified as 2,3~butanediol, but had no effect on silage pH (4.74 units). The 4.4% rate decreased the contents of acetic acid and ?..3-butanediol to very low levels and increased the pH to 5.02 units. The two higher rates of HCHO decreased nitrogen (N) breakdown in the silages and reduced ammonia production ill vitro.In Experiment 2, untreated silage and silage treated with HCHO (1.7% wjw of the dry matter) were ensiled in 6000 kg polythene-covered stacks. Formaldehyde treatment decreased the contents of acetic, propionic, n-butyric, and lactic acids, decreased the extent of N breakdown. and increased pH. The treatment decreased the osmotic pressure and conductivity of silage juice by 25 and 19% respectively, 2.3-butanediol comprised 2.40/< of the dry matter and was unaffected by HCHO treatment.Untreated silage showed a strong buffering action to both sodium hydroxide and artificial saliva solutions. Formaldehyde treatment before ensiling eliminated this effect.Secondarv fermentation was apparent in a 30 em deep surface layer of HCHO-treated silage, but was not present to any marked extent in untreated silage.

“…Gordon et al (1961) compared the preservation and feeding value of alfalfa stored as hay, haylage and silage and observed highest feeding values, animal acceptance, milk production and digestibility coefficients for barn dried hay. Yu (1977) heated dried alfalfa leaves, stems and hay at nine different temperatures (45 to 170 C) and for different durations (8.9 to 120 hours).…”

“…1969) and Ohio State (Porterfield and Pratt 1972) mentioned that under a well-managed forage feeding system cows fed stored feed produced more milk per hectare than those on pasture. Reporls from Cornell University (Trimberger et al 1955) and from the U.S. Department of Agriculture (Shepherd et al 1954) (Byers 1965;Gordon et al 1961;Murdoch and Rook 1963). Supplementary high moisture corn silage with good quality hay restored total forage DM intake and milk production to the level obtained with medium DM corn silage (Waldern 1972).…”
