Embodiment 1

[0030] Embodiment 1, the influence of calcium glycinate on piglet weaning diarrhea and production performance

[0031] A total of 120 weaned piglets weighing close to 5kg and 21 days old were selected and randomly divided into 4 groups according to the test requirements. Each group had 3 replicates, and each replicate had 10 piglets. Drink water freely, calculate the daily feed intake every day, observe and record the diarrhea situation every morning, weigh once every 10 days, and record the feed intake of each repetition. Then the diarrhea rate, daily weight gain and feed-to-weight ratio were counted.

[0032] Among them, diarrhea rate = number of pigs with diarrhea / total number of pigs × 100%, the result is as follows figure 1 shown.

[0033] It can be seen from the figure that there is a relatively high proportion of diarrhea in each group at the age of 7-9 days after weaning, and the diarrhea rate of each test group decreased significantly after the 9th day, and the diar...

Embodiment 2

[0039] Embodiment 2, Calcium Glycinate Effects on Weaning Piglet Mesenteric Lymph Node Lymphocyte Proliferation

[0040] Determination of lymphocyte proliferation in mesenteric lymph nodes requires slaughtering of animals. The specific method is as follows: slaughtering is divided into 3 times, and 3 21-day-old suckling piglets are taken for the first time, and serum is collected from slaughtering. Samples of duodenum, jejunum, and ileum are taken as unweaned previous comparison. Then 10 days after weaning and 20 days after weaning, 6 heads were taken from each group, slaughtered and sampled. The experimental pigs were fasted for 24 hours under free access to water before slaughter.

[0041] (1) Tissue sampling and processing

[0042] Carefully dissect the abdominal cavity, cut out the mesenteric lymph nodes in the middle of the jejunum with sterile scissors, and put them into a sterile bottle dish, which is first added with an appropriate amount of sterile PBS. Transfer to...

Embodiment 3

[0053] Example 3, Effects of calcium glycinate on villi height and lamina propria thickness of each intestinal segment

[0054] Making slices and measuring villous height (VH) and lamina propria deph (LPD):

[0055] (1) Take 1 cm from the middle section of duodenum, jejunum and ileum respectively 2 The intestinal wall was picked up carefully with tweezers and rinsed with saline, pasted on filter paper, flattened and trimmed, and fixed in 4% formalin.

[0056] (2) Rinse: Take out the fixed tissue block and trim it, put it into a large beaker and fill it with water, tie the mouth with gauze, and rinse with running water for 24 hours;

[0057] (3) Dehydration, transparency and wax dipping: the rinsed tissues were dehydrated on a Leica TP1020 dehydrator, transparent and wax dipped.

[0058] (4) Embedding, slicing, patching, displaying, and baking slices were embedded in the Leica EG1160 tissue embedding instrument; the embedding box with the tissue block was fixed on the stage o...

Abstract

The invention relates to a preparation method of a livestock feed premix as well as a product and application thereof. Feed contains calcium glycinate with the mass fraction of above 0.5%; with adoption of calcium glycinate, the post-weaning diarrhea rate of piglets is reduced, the diarrhea period is shortened, and the daily gain of the piglets is improved after the piglets are weaned for 10-20 days; meanwhile, the digestive ability of proteins of the piglets is promoted, and the immunity of the weaned piglets is improved. Therefore, the product has an important meaning for improving the performance of the weaned piglets.

Description

technical field [0001] The invention belongs to the field of livestock and poultry feed, and in particular relates to a method for preparing a livestock feed premix, and also relates to the prepared product and its application. Background technique [0002] With the popularization of animal husbandry technology, my country's aquaculture industry has developed rapidly. At present, the number of pigs, chickens and ducks raised in my country ranks first in the world. According to statistics, at the end of 2015, the number of pigs raised in my country reached 570 million, the amount of broiler chickens reached 5.15 billion, and the amount of layer poultry reached 3.2 billion. The number of certain species is still growing. However, there is still a large gap between my country's per capita intake of meat, eggs, and milk compared with developed countries. The output value of animal husbandry in my country accounts for 36% of the total output value of agricultural production, wh...
