Milk production from silage: comparison of grass, legume and maize silages and their mixtures

Abstract: The high rates of rumen fermentation, physical breakdown and passage rates from the rumen of legume silages lead to higher intakes than for grass silages of comparable digestibility. Although total tract digestibilities for legume silages and maize silages are often lower than for grass silages, milk yields are usually higher. A further benefit of legumes and maize is the reduced rate of decline in digestibility. Legume silages often lead to a reduction in milk fat concentration and increased levels of polyuns… Show more

“…Changing forage source in the diet of ruminants from grasses to legumes has been previously suggested as a possible strategy to reduce CH 4 production from ruminants (Benchaar et al, 2001;Beauchemin et al, 2009;Dewhurst, 2013). Legumes are generally characterized by low structural carbohydrates content, rapid physical breakdown, and high rumen fermentation rate compared with grasses (Janssen 2010;Dewhurst, 2013). Thus, feeding legumes as dietary forage source may increase DMI and passage rate compared with feeding grasses, which is expected to reduce methanogenic activities in the rumen (Martin et al, 2010;Dewhurst, 2013).…”

“…However, limited information exists on the effects of forage type on enteric CH 4 emissions in dairy cows. Changing forage source in the diet of ruminants from grasses to legumes has been previously suggested as a possible strategy to reduce CH 4 production from ruminants (Benchaar et al, 2001;Beauchemin et al, 2009;Dewhurst, 2013).

“…A deficiency of glucose sources in early lactation has primarily a negative impact on the milk protein level, as the lack of energy sources is responsible for the use of amino acids for glucose synthesis, rather than for lactose formation (8). Substantial amounts of fiber in a feed ration are conducive to an increased acetic acid level in the rumen (precursor of milk fat), and this effect occurs at the expense of propionic and butyric acid levels.…”

“…High energy value of entire plant, cob and grain is being excellently supplemented with high protein content of alfalfa, why those two feeds are regularly combined in cattle diet (TMR -total mixed ratio), mainly in the form of silage of entire maize plant, alfalfa hay or haylage and maize grain flour (Dewhurst, 2013). This possibility can be used during the silaging of entire maize plant by adding certain amount of green or wilted alfalfa fourth or fifth cut.…”
