Problems solved by technology

This method can determine the temperature and humidity environment of the breeding house at a certain point in time, but it cannot accurately evaluate the temperature and humidity environment of the pigs within a period of time
The temperature and humidity state of the breeding house generally changes dynamically with time, and the temperature and humidity state in different areas of the same livestock house also have differences, which makes it difficult to evaluate the temperature and humidity index calculated by thermometers and hygrometers at fixed points at regular intervals to evaluate a certain area within a period of time The temperature and humidity of active pigs

Embodiment Construction

[0020] Unless otherwise specified, the experimental methods, materials and reagents used in the following examples are conventional methods, materials and reagents, all of which can be obtained from commercial sources.

[0021] 1. Experimental animals

[0022] Select 40 Large White-Landrace binary nursery pigs with no significant difference in body weight and divide them into 5 groups at random, with 8 heads in each group (n=8). Provide enough drinking water, provide the same common feed (nutrient requirements refer to NRC standards), and eat freely.

[0023] 2. Test process and sample collection

[0024] The temperature and humidity environment of the nursery pigs in the control test in the respiration calorimetry cabin is the same for each group. In this test, the temperature and humidity environment is controlled by air conditioning. After later calculation, the environmental temperature and humidity indexes of the five groups of test pigs during the test period were 57.5...

Abstract

The invention discloses a method for evaluating the temperature and humidity state of the environment where nursery pig individuals grow through blood biochemical indexes. According to the method, thetemperature and humidity state of the environment where nursery pig individual growth is located is evaluated comprehensively by quantitatively detecting the following biochemical indexes in nurserypig blood at the same time: albumin, glutamic-pyruvic transaminase, glutamic oxalacetic transaminase, blood urea nitrogen, creatinine, glucose, triglyceride, total cholesterol, creatine kinase, C reactive protein, lactic acid, blood ammonia and immunoglobulin M.

Description

technical field [0001] The invention belongs to the technical field of pig breeding environment evaluation, and specifically relates to a method for evaluating the environmental temperature and humidity state of nursery pigs. The idea of ​​this technology can also be extended to the field of environmental temperature and humidity somatosensory evaluation of other animals and even humans. Background technique [0002] The breeding environment is one of the factors that determine the productivity of pig breeding, and its contribution rate to pig breeding is as high as 25%. Improving the breeding environment is a necessary means to improve the productivity of pig breeding. The temperature and humidity state is the most important part of the breeding environment, which can be evaluated by the temperature and humidity index. The temperature and humidity environment can affect the productivity of pig breeding from multiple angles. The immunity of pigs in the temperature and humidi...
