Embodiment 1

[0018] 1. The formula of the substrate feed is shown in Table 1.

[0019] Table 1 Formula of substrate feed (unit: kg, air-dried basis)

[0020]

[0021] 2. Specific application of lanthanum chloride in inhibiting ruminal methane emission in substrate feed:

[0022] 2.1 Test material

[0023] Lanthanum chloride was purchased from Tianjin Alfa Aesar Company, the purity is greater than 99.9%, and the molecular weight of lanthanum chloride is 245.3.

[0024] 2.2 Test animals

[0025] In this experiment, 2 Simmental cattle in good body condition, installed with permanent rumen fistula, and with an average body weight of 550 kg were selected as rumen fluid donors. Feed the same amount twice a day at 07:00 and 17:00, and drink water freely.

[0026] 2.3 Test diet (in vitro culture substrate)

[0027] After air-drying the feed formulas 1-4 in Table 1, crush them through a 1 mm mesh sieve for later use.

[0028] 2.4 Experimental design

[0029] Feed formulations 1-4 were use...

Abstract

The invention relates to application of lanthanum chloride to inhibition of rumen methane emission in ruminant feeds. The rumen methane emission can be reduced to the maximum extent by adding 0.4-1.0mmol lanthanum chloride/kg dry matter (DM) into a feed with the neutral detergent fiber content being 30%-55%; the lanthanum chloride is low in cost, safe, nontoxic and low in residue content in the actual application and cannot cause injury to domestic animals and human health.

Description

technical field [0001] The invention relates to the application of lanthanum chloride to suppress rumen methane emission in ruminant feed, and belongs to the technical field of animal nutrition and feed. Background technique [0002] Carbohydrates in the feed can be fermented by microorganisms in the rumen of ruminants to produce volatile fatty acids (Volatile fatty acid, VFA), and also produce methane. VFA is used by ruminants as an energy source, and methane is released into the atmosphere through belching, which not only causes feed energy loss, but also aggravates the global greenhouse effect. During ruminal metabolism in ruminants, approximately 2–15% of feed energy is lost in the form of methane (Holter and Yong, 1992). Methane is a greenhouse gas closely related to global climate change, and its effect on global warming accounts for 15%-20% of all effects on climate warming, and its greenhouse effect is 62 times that of carbon dioxide (Moss et al., 2000). Therefore,...
