Problems solved by technology

[0003] At present, the current nutritional quality evaluation of pig diets in my country mainly focuses on sensory evaluation such as odor, color, freshness and other items, as well as the determination of the content of certain chemical substances. Such evaluation methods are subject to subjective influence and low accuracy.

Embodiment 1

[0105] The formula of a group of diets to be tested: 56.4 parts of corn, 21.27 parts of soybean meal, 8 parts of soybean oil, 2.66 parts of soybean hulls, 5 parts of wheat bran, 3 parts of corn gluten powder, 1 part of anhydrous calcium hydrogen phosphate, 0.42 parts of stone powder, salt 0.3 part, 1 part of premix, 0.75 part of lysine, 0.1 part of methionine, 0.1 part of titanium dioxide.

[0106] The body weight G of growing and finishing pigs suitable for feeding with this diet is 24-32Kg. The weight G is in the range of 20-35 Kg, therefore, a=46.3.

[0107] (1) Prepare each solution according to the following preparation method:

[0108] Resazurin solution: weigh 0.2g resazurin and dissolve in 200ml sterile water;

[0109] Hemin solution: Weigh 0.1g of hemin and dissolve it in 5ml of 0.05mol / L NaOH solution, dilute it to 1L with sterile water, and then inject CO 2 ;

[0110] Trace mineral solution: weigh 0.025g MnCl respectively 2 4H 2 O, 0.020g FeSO 4 ·7H 2 O. 0.0...

Embodiment 2

[0127] The formula of the second group of the diet to be tested: 53 parts of corn, 20.8 parts of soybean meal, 8 parts of soybean oil, 7.23 parts of soybean hulls, 5 parts of wheat bran, 3 parts of corn gluten powder, 0.72 parts of anhydrous calcium hydrogen phosphate, 0.05 parts of stone powder, salt 0.3 part, 1 part of premix, 0.7 part of lysine, 0.1 part of methionine, 0.1 part of titanium dioxide.

[0128] The body weight G of growing and finishing pigs suitable for feeding with this diet is 24-32Kg. The weight G is in the range of 20-35 Kg, therefore, a=46.3.

[0129] (1) Prepare each solution according to the following preparation method:

[0130] Resazurin solution: weigh 0.2g resazurin and dissolve in 200ml sterile water;

[0131] Hemin solution: Weigh 0.1g of hemin and dissolve it in 5ml of 0.05mol / L NaOH solution, dilute it to 1L with sterile water, and then inject CO 2 ;

[0132] Trace mineral solution: weigh 0.025g MnCl respectively 2 4H 2 O, 0.020g FeSO 4 ·...

Embodiment 3

[0155] The formulas of the three groups of rations to be tested: 49.7 parts of corn, 20.04 parts of soybean meal, 8 parts of soybean oil, 11.85 parts of soybean hulls, 5 parts of wheat bran, 3 parts of corn gluten powder, 0.1 part of anhydrous calcium hydrogen phosphate, 0.3 part of table salt, 1 part of mixture, 0.8 part of lysine, 0.11 part of methionine, 0.1 part of titanium dioxide.

[0156] The body weight G of growing and finishing pigs suitable for feeding with this diet is 24-32Kg. The weight G is in the range of 20-35 Kg, therefore, a=46.3.

[0157] (1) The digestible energy content of the four groups of diets was detected using a bionic digester, and DDE = 17.35 MJ / Kg.

[0158] (2) According to body weight G, the average daily feed intake ADFI is 1.45Kg / d.

[0159] (3) According to the formula Calculated PBGI = 0.558MJ / d.

[0160] (4) Evaluation results: PBGI was greater than 0.5, and it was determined that the three dietary groups were suitable for feeding grow...

Abstract

The invention discloses a method for evaluating the nutritional quality of growing and fattening pig diets, and relates to the technical field of breeding. The method comprises the following steps: obtaining the digestible energy content DDE of the ration to be tested; obtaining the average daily feed intake ADFI of the ration to be tested; calculating the evaluation index PBGI of the ration to be tested according to formula I; according to the evaluation index PBGI, evaluates the nutritional quality of the diets under test. The present invention calculates the evaluation index PBGI of the diet to be tested by formula I, and based on the evaluation index PBGI, the nutritional quality of the diet to be tested can be evaluated, with low cost and fast speed. In addition, the nutritional quality of the diet is quantified, and its evaluation The result accuracy is high.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a method, device and storage medium for evaluating the nutritional quality of growing and fattening pig diets. Background technique [0002] Piglets are divided into piglets, growing pigs, and fattening pigs from birth, and fattening pigs are a growth stage of commercial pigs. Compared with sows and piglets, the organs of fattening pigs have matured and their resistance is relatively enhanced. The economic benefits of growing and finishing pigs are mainly reflected in growth rate, feed utilization rate and lean meat percentage. The nutrition of pigs needs to be prepared with a reasonable diet to maximize the lean meat rate and meat-to-feed ratio, which requires a reasonable evaluation of the nutritional quality of the diet for growing and finishing pigs. [0003] At present, the existing nutritional quality evaluation of pig diets in my country mainly focuses on sensory evalua...
