Embodiment 1

[0017] 1. Materials

[0018] 1.1 Additives N-carbamoylglutamic acid (purity ≥ 97%), vitamin C (purity ≥ 99%)

[0019] 1.2 Large white sows of animal law system (a large breeding pig farm in Beijing)

[0020] 2. Methods and results

[0021] 2.1 Experimental design

[0022] The sow experiment was carried out from July to August 2012. During the experiment, the average temperature was 25.8 degrees, and the average daily maximum temperature was 30.2 degrees. The number of days with the daily maximum temperature higher than 30 degrees Celsius was 47 days; the average humidity was 58.5%.

[0023] In the sow feeding experiment, 120 French Large White sows of the same age and parity were selected and randomly divided into 6 groups, 20 in each group. Each group randomly received one of the treatments in Table 1 during the prenatal January-weaning period, and the amount of additives used in each group is shown in Table 1. After 3 days of using the additive, start to record the daily...

Abstract

The invention provides application of NCG (N-CarbamylGlutamate) and VC (Vitamin C) in preparing heat stress-resisting feed additives or feeds. According to the invention, when the NCG and the VC are combined, the heat stress resisting ability of livestock (particularly sows) can be remarkably increased, so that the NCG and the VC produce a synergistic effect, can be widely popularized and applied in the field of animal husbandry and have good market effect and social effect.

Description

technical field [0001] The invention relates to the field of livestock breeding, in particular to the application of NCG and VC in the preparation of anti-heat stress feed additive or feed. Background technique [0002] Feed additives refer to small or trace substances added during feed production, processing and use, which are used in small amounts but have significant effects in feed. Feed additives include nutritional additives, pharmaceutical additives, and some additives that promote digestion or metabolism, which have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed costs, and improving animal product quality. . [0003] N-carbamylglutamate (N-Carbamylglutamate, NCG), the Chinese name is N-carbamylglutamate. In the past, NCG was mainly used in humans. On the one hand, as a nutritional enhancer, it can significantly increase muscle production (content), and it is added to...
