Embodiment 1

[0009] Apply the feed of the present invention to simulate the rumen digestion and metabolism of buffalo in vitro and apply the bottle system to simulate the rumen digestion and metabolism of buffalo in vitro. The method adopts the pressure reading type in vitro gas production system (Reading pressure system, RPT) of Mauricio et al. (1999) to carry out in vitro rumen fermentation and cultivation, The anaerobic artificial rumen buffer was prepared according to the method of Menke and Steingass et al. (1988). The substrate formulation is shown in Table 1 below.

[0010] The rumen fluid comes from three buffaloes with a body weight of about 400±5kg installed with permanent rumen fistulas as donor animals for rumen fluid. The experimental cows were fed in a tethered manner, fed twice a day at 8:00 and 17:00, had free access to water, conventional light, deworming and management.

[0011] Extract 10 μl of gas after substrate fermentation for 6 hours, 12 hours, and 24 hours. Use ma...

Abstract

The invention discloses a feed capable of reducing methanogenesis of gastrointestinal tracts of buffalos. The feed is composed of following components in percentage by mass (on the basis of air dry matters): 25.00%-27.00% of corns, 7.50%-11.25% of soya bean meal, 3.75%-7.50% of beer residues, 25.00%-27.00% of silo corns, 22.50%-26.25% of pennisetum purpureum schum, 2.00%-7.50% of fermented cassava residues, 0.13%-0.33% of cysteamine hydrochloride and 1.00%-3.00% of sodium bicarbonate. According to the feed, the methanogenesis of the gastrointestinal tracts of milk buffalos is reduced by scientifically matching a rough feed and combining and adding the cysteamine hydrochloride. Different from other methods, the cysteamine hydrochloride is added on the basis of an authorized patent, namely a formula of a feed capable of reducing methanogenesis of gastrointestinal tracts of buffalos (the application number is 201110189541.X; an authorization patent number is ZL201110189541.X), so as to reduce the emission amount of methanol of the gastrointestinal tracts of cud chewers.

Description

technical field [0001] The invention belongs to ruminant feed formula, in particular to a feed for reducing methane generation in the gastrointestinal tract of buffalo. Background technique [0002] The global climate is heating up. The convening of the Copenhagen Conference in Denmark in December 2009 gave people a deeper understanding of the severity of the climate change phenomenon, and formed a political consensus on controlling greenhouse gas emissions. It also aroused scientists' concerns about methane emissions, one of the greenhouse gases However, methane produced by rumen fermentation of ruminants accounts for about 23% of the total anthropogenic methane production and 15% of the total global methane emissions. At present, the nutritional way to reduce methane production in the gastrointestinal tract of ruminants is mostly through methane inhibitors. These inhibitors have an inhibitory effect on the environmental microorganisms in the rumen, inhibiting methane bacte...
