[0015] Example 1

[0016] 1. Materials

[0017] 1.1 Additives N-carbamoylglutamic acid (purity ≥ 97%), vitamin C (purity ≥ 99%)

[0018] 1.2 Large white sows of animal law system (a large breeding pig farm in Beijing)

[0019] 2. Methods and results

[0020] 2.1 Experimental design

[0021] In the sow feeding experiment, 200 French Large White sows of the same age and parity were selected and randomly divided into 10 groups, 20 in each group. Each group was randomized to one of the treatments in Table 1, and the feeding stages and additive amounts of each group were shown in Table 1.

Abstract

The invention provides a feed additive and an application thereof. The feed additive provided by the invention comprises N-carbamylgulatamate (NCG) and vitamin C (VC), wherein the weight ratio of the NCG to the VC is (1-2): (1-2). According to the feed additive, NCG and VC are combined, and production performance of livestock, especially a sow, can be obviously improved, so that the NCG and the VC have an synergistic effect, and the feed additive can be widely popularized and applied in the field of livestock breeding and has a good market effect and a good social effect.

Description

technical field [0001] The invention relates to the field of livestock breeding, and specifically relates to a feed additive, and also relates to the application of the feed additive in improving the production performance of sows. 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 muscl...
