example 1

[0031] The optimization of formula in the example 1 liquid composite acidity regulator

[0032] The formulation screening of compound acidity regulator was carried out by means of laboratory analysis.

[0033] 1. Test materials and methods

[0034] 1.1 Test material

[0035] Analytical pure formic acid, acetic acid, citric acid, fumaric acid, lactic acid and hydrochloric acid were selected as test materials.

[0036] Preparation of compound acid solution Prepare 20 compound acids according to Table 2, and gradually dilute them with sterile saline to make 10%, 1.0%, 0.1% and 0.02% solutions respectively for later use.

[0037] 1.2 Experimental design

[0038] Using the method of "uniform formula design", using formic acid, acetic acid, citric acid, fumaric acid, lactic acid, and hydrochloric acid as the main ingredients of acidity regulators, 6 kinds of acids were combined into 20 treatments, and each treatment had 5 repetitions. The regression equation between the percenta...

[0059] Preparation of Example 2 Liquid Composite Acidity Regulator and Calf Feeding Test Effect

[0060] The effect of adding compound acidity regulators to milk replacer was verified by calf feeding experiment.

[0061] 1. Test materials and methods

[0062] 1.1 Test material

[0063] The liquid compound acidity regulator is prepared by the Feed Research Institute of the Chinese Academy of Agricultural Sciences, and its formula is 40.74% formic acid, 50.62% hydrochloric acid, and 8.64% citric acid. All assay acids were diluted to 10% solutions prior to use.

[0064] 1.2 Experimental design

[0065] Divided into control group and test group. The calves in the control group were fed conventional milk replacer emulsion with a pH value of 6.2, and the compound acidity regulator was added to the milk replacer emulsion in the test group to reduce the pH value to 5.0. Six replicates were set up for each treatment, with one calf per replicate.

Abstract

The invention relates to a liquid composite acidity regulator used in a calf and lamb milk replacer, belonging to the fields of animal nutrition of animal science disciplines and forage sciences. The liquid composite acidity regulator provided by the invention is prepared by taking formic acid, hydrochloric acid and citric acid as raw materials through a scientific composition. The liquid composite acidity regulator is used in calf and lamb milk replacer emulsion so that the pH value of the emulsion is reduced to 5.0-5.5. The liquid composite acidity regulator can be added when the milk replacer is fed to calves and lambs. The liquid composite acidity regulator is convenient to prepare and use. By using the liquid composite acidity regulator, the growth performance of young animal can be improved; the blood gas index can be improved, therefore, the growth and the development of the calves and the lambs can be improved. By means of the application of the liquid composite acidity regulator used in the calf and lamb milk replacer disclosed by the invention, the visible economic benefit and ecological benefit can be brought about in the animal husbandry, in particular dairy cow and meat sheep cultivation industries.

Description

[technical field] [0001] The invention relates to the preparation of a liquid compound acidity regulator containing organic acid and inorganic acid, which is used to reduce the pH value of milk replacer emulsion when feeding calves or lambs, and belongs to the field of animal nutrition and feed science of animal husbandry. The invention also relates to the types of raw materials needed to prepare the liquid composite acidity regulator, the preparation method and the use method. [Background technique] [0002] Birth and weaning (weaning off breast milk and feeding milk replacers) is a great stress for young calves and lambs. At that time, the digestive system of calves and lambs is not fully developed, and the secretion of gastric acid is insufficient, resulting in problems such as decreased activity of digestive enzymes and decreased digestive capacity. The appearance of calves and lambs shows symptoms such as diarrhea, which eventually leads to poor growth and even death. ...
