Problems solved by technology

However, direct inhalation of nitric oxide costs more and requires higher equipment conditions, and long-term inhalation of nitric oxide can also lead to methemoglobinemia
These factors limit the application of inhaled nitric oxide in the treatment of pulmonary arterial hypertension

Embodiment

[0035] 1. Feed preparation.

[0036] According to the present invention, N-carbamoylglutamic acid can be mixed with feed, such as complete compound feed. The preparation method of the feed is simple, and the base material is mixed evenly, and then the auxiliary material N-carbamoylglutamic acid is added and mixed evenly.

[0037] The premix was provided by Qinghai Jiangheyuan Agriculture and Animal Husbandry Technology Development Co., Ltd.

[0038] In the present embodiment, the formula of feed is as follows:

[0039] Table 1 Cattle Feed Formula

[0040]

[0041] Wherein, the above-mentioned proportions are calculated by dry weight.

[0042] The dry matter intake of each cow is 3kg-25kg, the daily dosage of each cow is 20g, and the proportion of feed is 0.08w / w%-0.66w / w%.

[0043] 2. Animals and feeding methods.

[0044] 1) The Holstein cows used in the experiment were introduced from low-altitude areas (Xi'an, Shaanxi) to high-altitude areas (Lhasa, Tibet) and raised...

Abstract

The invention relates to N-carbamylglutamate-containing cattle feed and application of N-carbamylglutamate in the field of preventing and treating pulmonary heart-lung diseases. The invention also relates to cattle feed, a feed additive or water additive or lick block used for improving heart-lung functions of cattle and preventing and treating pulmonary heart-lung diseases. Through eating the N-carbamylglutamate-containing cattle feed, cattle have expanded blood vessels, thus significantly reducing the average pulmonary artery blood pressure, peripheral systolic pressure, the heart rate and the attack rate of pulmonary hypertension, and reducing cattle cardiovascular system damage caused by low oxygen, and therefore, a function of preventing or treating cattle pulmonary heart-lung diseases is achieved.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to cattle feed containing N-carbamoylglutamic acid and the application of N-carbamoylglutamic acid in the prevention and treatment of pulmonary cardiopulmonary diseases. Background technique [0002] The Qinghai-Tibet Plateau has a unique high-altitude low-oxygen environment. High-altitude hypoxia causes livestock to be susceptible to altitude sickness, which brings greater economic losses to the livestock breeding industry in high-altitude areas. Studies have reported that there is a risk of altitude sickness at altitudes higher than 2,500 meters, and the incidence increases with altitude. The average altitude of my country's Qinghai-Tibet Plateau is higher than 2,500 meters, and some areas of Gansu Province and Sichuan Province are also higher than 2,500 meters above sea level. Livestock raised in these areas are at risk of suffering from altitude sickness. Cattle are com...
