Problems solved by technology

2. The digestive organs are underdeveloped, the function of the digestive glands is not perfect, and the stomach volume is small
3. Lack of immunity, suckling pigs are prone to diseases
4. The development of the cerebral cortex is not perfect, the function of regulating body temperature is poor, and the skin is thin and the hair is thin, and the subcutaneous fat is less. Therefore, it is very important to do a good job of heat preservation for suckling pigs
However, the existing feed for suckling pigs is mainly coarse grains such as corn and wheat, which cause a great burden on the digestive system and affect the food intake of suckling pigs.

Embodiment 1

[0017] A method for preparing liquid feed for suckling pigs, comprising the preparation of fermented corn flour, the preparation of citrus peel extract, and the preparation of feed, wherein the specific steps of preparing the citrus peel extract are as follows: dry the citrus peel and pulverize it to 40 mesh; Add the extract containing 2,6-di-tert-butyl-4-methylphenol and catechin at a ratio of 1:11 (g / mL), and conduct ultrasonic extraction for 20 minutes at a temperature of 30°C and an ultrasonic power of 300W. Filtrate, repeat the extraction 4 times, and combine the filtrates to obtain the citrus peel extract. The preparation method of the citrus peel extract is simple and feasible. Ultrasonic waves form small bubbles in the extract and break the small bubbles, thereby generating shock waves, effectively breaking biological cells and tissues, and achieving high-efficiency extraction of carotenoids in a short period of time. Objective: The extraction rate and extraction rate ...

Embodiment 2

[0026] A method for preparing liquid feed for suckling pigs, comprising the preparation of fermented corn flour, the preparation of citrus peel extract, and the preparation of feed, specifically comprising the following steps

[0027] 1) Preparation of citrus peel extract: dry the citrus peel and crush it to 50 mesh, add 2,6-di-tert-butyl-4-methylphenol and catechin at a ratio of 1:10 (g / mL) to the material to liquid The extract of element, at temperature is 35 DEG C, ultrasonic power is the condition of 250W ultrasonic extraction 25min, filter, repeat extraction 3 times, merge filtrate, obtain citrus peel extract, above-mentioned extract is that volume ratio is 1:0.6: 2.0 A mixture of acetone, petroleum ether and ethanol, 0.1% of 2,6-di-tert-butyl-4-methylphenol and 0.025% of catechin contained in the above extract;

[0028] 2) Preparation of fermented corn flour: Grind dry corn flour to 100 mesh, add water to 50% water content, then add tryptophan, mix evenly, autoclave for ...

Abstract

The invention discloses a preparation method of a liquid feed for suckling pigs. The preparation method comprises the following steps of preparing fermented corn powder, preparing a citrus peel extract, and preparing the feed, wherein the step of preparing the citrus peel extract comprises the substeps of drying citrus peel, performing crushing, adding an extraction solution containing 2,6-Di-tert-butyl-4-methylphenol and catechin, performing ultrasonic extraction, performing filtering, performing repeated extraction, and merging filtrate to obtain the citrus peel extracting solution. The preparation method disclosed by the invention has the beneficial effects that the preparation method is simple and feasible, the prepared feed is similar to breast milk in shape, development in stomachs and intestines of the suckling pigs is facilitated, the prepared feed contains a large quantity of carotenoids, water-soluble selenoprotein and selenium amino acid, the feed is easy to absorb and utilize by the suckling pigs, and the liquid feed has the effect of killing pests and is good in palatability.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a preparation method of liquid feed for suckling pigs. Background technique [0002] Physiological characteristics of suckling pigs: 1. Rapid growth and vigorous material metabolism. The birth weight only accounts for less than 1% of the adult pig's body weight, 2 times the birth weight at the age of 10 days, 6 times at the age of 30 days, and 14 times at the age of 60 days. 20-day-old suckling pigs deposit 9-14 grams of protein per kilogram of body weight per day, while adult pigs only deposit 0.3-0.4 grams, which is equivalent to 30-35 times that of adult pigs. The energy and mineral deposits are also higher than those of adult pigs, which shows that suckling pigs have strong material metabolism and need a full-price diet with high nutrient concentration and balance. 2. The digestive organs are underdeveloped, the function of the digestive glands is not perfect, and the stomach ...
