Embodiment 1
[0041] Preparation of 1L Nutrient Health Solution for Suckling Pig
[0042] 1. Preparation of Immunoglobulin IgG
[0043] Take 2L of fresh pig blood and add 200ml of 2.5% (w / v) sodium citrate for anticoagulant treatment, centrifuge at 8000r / min, 4°C for 10min, take the supernatant and dilute with 3.5 times of distilled water, put it in an ice bath, under the condition of strong stirring , add pre-cooled absolute ethanol in an amount of 30% (v / v), until it produces a precipitate, and centrifuge to get the precipitate. Suspend the precipitate in 500ml of 0.2mol / L NaCl solution, adjust the pH to 4.2 with hydrochloric acid to form a precipitate, centrifuge to take the supernatant, adjust the pH of the supernatant to about 7.2 with NaOH, add pre-cooled absolute ethanol, and add 30% (v / v), put it in an ice bath to make it precipitate, and the precipitate obtained by centrifugation is crude IgG. Pack the pretreated DEAEcellulose-52 into the column, load and elute the extracted crud...
Embodiment 2
[0048] Examples of the application and effect of suckling pig nutrition and health care solution (hereinafter referred to as nutrient solution) on early weaned piglets:
[0049] 1. Materials and methods
[0050] A total of 600 healthy 4-week-old early-weaned Duroc piglets were selected and randomly divided into 2 groups, with 3 replicates in each group and 100 piglets in each replicate. The test period is 15 days. The basal diet of the experiment was corn-soybean meal type, on which nutrient solution and flavomycin were added. Other conditions were the same for both groups.
[0051] 2 Results and analysis (see Table 1)
[0052] Table 1 Comparison of the effects of nutrient solution and flavomycin on the performance of early weaned piglets
[0053]
[0054]
[0055] It can be seen from Table 1 that throughout the test period, the survival rate of the nutrient solution group was higher than that of the flavomycin group, and the difference was significant; in the early ...
Embodiment 3
[0058] Examples of the effect of nutrient solutions on the performance of piglets deficient in maternal milk:
[0059] 1. Materials and methods
[0060] The Duroc piglets were randomly divided into 3 groups, 30 piglets each in the control group, antibiotic group and nutrient solution group, and the test period was 15 days. The basic diet of the experiment was milk, and other conditions were the same for each group.
[0061] 2. Results and analysis, the test results are shown in Table 2.
[0062] Table 2 Effect of nutrient solution on production performance of weaned piglets
[0063]
[0064] It can be seen from Table 2 that the diarrhea rate of the control group was significantly higher than that of the antibiotic group and the nutrient solution group, and the antidiarrheal effect of the nutrient solution group was better than that of the antibiotic group. The daily weight gain of the nutrient solution group was significantly better than that of the control group and the...
