Embodiment 1
[0017] Embodiment 1: the preparation of feed additive
[0018] Preparation of the extract: Ultrasonic extraction is used to extract the effective components in the plants respectively, and the plant extracts are simply mixed according to the following proportions. The specific parameters of ultrasonic extraction are that the extracted medicinal materials need to be crushed and passed through a 40-mesh sieve, the extraction solvent is anhydrous ether, the weight ratio of the extraction material to liquid is 1:10, the ultrasonic power is 200W, the extraction temperature is 45°C, and the extraction time is 2 Hour.
[0019] A mixture of 30% by weight of Yucca extract, 10% by weight of Codonopsis pilosula extract, 15% by weight of Divine Comedy extract, 20% by weight of thyme extract and 25% by weight of orange peel extract.
Embodiment 2
[0020] Embodiment 2: effect verification test
[0021] 360 healthy growing pigs of Wai Sanyuan "Du Changda" breed with a body weight of 7.0±0.5kg were randomly divided into 2 treatment groups, each treatment group had 6 replicates, and each replicate had 30 pigs. The experimental diet was formulated according to the nutritional requirements of pigs in the US NRC (2012). The two groups of animals were fed with common pig feed (control group) and experimental diet (test group) on the market respectively. The specific ingredients are shown in Table 3. The test period was 50 days. Feed intake and mortality were recorded during the test. At the end of the test, all pigs were weighed to calculate the weight gain and feed conversion efficiency.
[0022] Pig blood was collected on the 40th day of the experiment, (CA530-16 automatic hematology analyzer was used to measure and classify the number of white blood cells (Switzerland MEDONIC company), and the ratio of cAMP / cGMP was de...
