Embodiment 1

[0034] To prepare the nutritional additive of the present invention and corresponding feed, the raw material consumption (unit: Kg) is as follows in Table 1 in each formula.

[0035]

[0036]

[0037] In the above table, 1. The trace element premix provides per kilogram of feed: iron, 100mg; copper, 5mg; manganese, 5mg; zinc, 100mg; iodine, 0.2mg; selenium, 0.3mg.

[0038] 2. The multivitamin premix provides per kilogram of feed: vitamin A, 3,000IU; vitamin D, 250IU; vitamin E, 25IU; vitamin K, 0.6mg; vitamin H, 0.1mg; folic acid, 0.5mg; pantothenic acid, 10mg; Vitamin B2, 3.5mg; Vitamin B1, 1.2mg; Pyridoxine, 3.5mg; Niacin, 50mg.

[0039] The preparation and use methods of the nutritional additives are as follows: (1) the trace element premix is ​​made by weighing and mixing feed grade raw materials according to the proportion; (2) the multivitamin premix is ​​prepared by weighing and mixing the raw materials according to the proportion (3) The nutritional additive can...

Embodiment 2

[0041] Select 30 ternary sows with a body weight of about 35Kg, and randomly divide them into 3 groups according to body weight, with 10 heads in each group. Group A is the control group. Add sodium selenite (Na2SeO3) test group (the final concentration of selenium in the prepared feed is 0.3mg / kg) in the trace element premix, C group is the feed formulated with this nutritional additive (trace element Added in the premix is ​​selenium-enriched spirulina, and the final concentration of selenium in the formulated feed is 0.3mg / kg).

[0042] The used feed formula of control group (group A) is: calcium carbonate, 0.60%; Dibasic calcium phosphate, 1.80%; Salt, 0.30%; L-lysine, 0.50%; Acid, 0.18%; trace element premix, 0.50%; multivitamin premix, 0.50%; the balance is corn 68.72% and soybean 26.80%.

[0043]The feed formula used in group B is: calcium carbonate, 0.60%; calcium hydrogen phosphate, 1.80%; salt, 0.30%; L-lysine, 0.50%; L-methionine, 0.10%; L-threonine, 0.18% ; Trace...

Abstract

The invention discloses a nutritional additive for improving pork quality. The nutritional additive comprises the following components in percentage by weight: 0.55%-0.60% of calcium carbonate; 1.25%-1.80% of calcium hydrogen phosphate; 0.25%-0.3% of edible salt; 0.21%-0.50% of L-lysine; 0.04%-0.10% of L-methionine; 0.04%-0.18% of L-threonine; 0.40%-0.60% of trace element premixing agent; 0.40%-0.60% of compound vitamin premixing agent; and the balance carrier. The trace element premixing agent includes selenium yeast, and the final concentration of selenium in prepared feed is 0.3 mg / kg. The nutritional additive has a reasonable formula, stable raw material sources, low cost, and a simple production process, and can effectively improve the resistance and growth performance of pigs under the heat stress condition and improve the pork quality.

Description

technical field [0001] The invention relates to a nutritional additive for improving the quality of pork, in particular to a nutritional additive with anti-heat stress effect, especially for pig feed. Background technique [0002] In recent years, climate anomalies and extreme weather events have occurred frequently around the world, and the rise in global temperature is the most obvious sign. Heat stress due to rising temperatures is one of the most important environmental stressors in livestock farming worldwide. Severe heat stress can adversely affect pig growth performance, carcass quality and meat quality. According to statistics, the loss caused by heat stress to the hog industry in the United States exceeds 300 million U.S. dollars every year, and the loss caused by heat stress to the global livestock industry exceeds billions of dollars. As a big pig raising country, my country may suffer even more serious economic losses. [0003] In addition, adverse effects ind...
