Processing technology of special liquid yoghourt for suckling piglets

Abstract

The invention discloses a processing technology of special liquid yoghourt for suckling piglets, which comprises the following steps: mixing water and oil, heating to 65-75 DEG C, stirring at a high speed for 10-15 minutes, adding an emulsifying thickener and glucose into a water-oil mixed solution, keeping the temperature, and continuing stirring for 15-20 minutes; adding whey powder, whole milkpowder and amino acid into a stabilizer solution and then mixing and stirring for 10 min; cooling the mixed feed liquid, diluting citric acid and lactic acid with water, slowly adding the diluted citric acid and lactic acid into the feed liquid, and adjusting the pH value to be 4-5; heating the feed liquid to 60-70 DEG C, and homogenizing under the pressure of 15-25 Mpa for one time; carrying outhot filling on the feed liquid at 55-60 DEG C, and carrying out water bath sterilization on the filled feed liquid at 75-90 DEG C for 10-30 minutes; and boxing and storing. The liquid yoghourt is highin dry matter content, appropriate in crude protein and crude fat content, balanced in amino acid, easy to digest, good in palatability and convenient to feed, the nutrient content is close to breastmilk components, on-site manual investment can be reduced, the survival rate of suckling piglets before and after weaning can be remarkably increased, and the weaning rate of certified products is increased.

Description

technical field [0001] The invention relates to the technical field of liquid yoghurt, in particular to a processing technology of liquid yoghurt specially used for suckling piglets. Background technique [0002] With the improvement of genetic breeding technology, variety improvement and feeding management level, the reproductive performance of purebred, binary and backcross sows has been fully tapped, and the total litter size has been greatly improved. Food intake and number of teats will not increase with the increase of total litter size, and the phenomenon of insufficient milk in sows affecting pre-weaning mortality and even weaning weight has become increasingly prominent; in addition, affected by the domestic ASF epidemic, three-yuan sow fat Breeding has become the norm, and its poor farrowing performance and lactation ability have also become the main reasons affecting the benefits of various breeding enterprises. Therefore, how to make up for the lack of lactation...

Problems solved by technology

[0003] At present, various formulations of creep feed are widely used in domestic pig farms during lactation, including powder feed and pellet feed, both of which feed solid feed directly to piglets. The existing problem is that piglets are directly converted from breast milk. When it is solid feed, the opening is slow, and the feed intake during the whole lactation period is limited; another feeding method is milk powder, which needs the on-site feeding personnel to boil the water and let it cool down before brewing the milk powder, which partially solves the problem of piglet feeding. Because of the opening problem caused by the change of feed form, but the shelf life is short, which greatly increases the workload on site

This project aims to scientifically select a reasonable proportion of raw materials according to the feeding preferences and nutritional needs of piglets during lactation, and cooperate with reasonable dairy processing technology to develop a special liquid yogurt for suckling piglets that can be stored at room temperature and connect in a more gentle way Make the transition between breast milk and solid creep feed, so as to obtain good weaning weight, feed intake and weight gain after weaning, and improve the current situation of low weaning weight, high weaning stress, high diarrhea rate and high mortality
