Problems solved by technology

Most of the existing feces and urine devices and metabolic cages are relatively simple and the environment is relatively harsh, which is not conducive to postoperative recovery and sample collection of animals. The feces and urine cannot be separated. The feces and urine are mixed together with a large amount of water and feed. , the experimental data is inaccurate, and there is no uniform specification of the device so far

Embodiment 3

[0039] The metabolic cages of the present invention and the conventional metabolic cages will be discussed in detail below, taking pigs as the representative of breeding animals.

[0040] Get 20 kinds of healthy growing pigs whose body weight is 55 ± 3.0kg, and are randomly divided into 2 treatment groups, each treatment group has 10 repetitions, and are respectively raised in the metabolic cages of the present invention and the existing pigs. There are technical metabolic cages. The experimental diet was configured according to the nutritional requirements of pigs in the US NRC (2012). Wherein treatment 1 is the metabolic cage group of the present invention, and treatment 2 is the prior art metabolic cage group, and the experimental period is 60 days (July-August). During the experiment, the feeding management program and immunization program were carried out according to the conventional commercial pig feeding management manual. After one week of pre-feeding, the blood can...

Abstract

The invention discloses a dung-urine separator and a metabolism cage for livestock nutrition research; the dung-urine separator comprises a bottom plate and side plates arranged on two sides of the bottom plate; the bottom plate and the side plates form a groove shape; the front portion of the bottom plate is provided with an urine outlet; the height of one end, close to the urine outlet, of the bottom plate inner surface is lower than that of the other end, far away from the urine outlet, of the bottom plate inner surface; the height of one end, close to the urine outlet, of the side plate inner surface is lower than that of the other end, far away from the urine outlet, of the side plate inner surface; the middle portion and rear portion of the bottom plate inner surface are provided with dung baffle plates, and the bottom of the dung baffle plates are provided with holes; a forage baffle plate is arranged above the urine outlet. The dung-urine separator can fully separate the livestock dung from urine, thus solving dung and urine separate collection problems, and providing guarantee for experiment results.

Description

technical field [0001] The invention belongs to the technical field of animal nutrition, and in particular relates to a feces and urine separation device and a metabolic cage for livestock nutrition research. Background technique [0002] The growth environment of animals plays a vital role in the experimental results, and animal surgery and metabolic experiments are an important medium for studying animal nutrition. Blood can reflect the physiological and biochemical changes of animals after ingesting nutrients. Feces and urine can It is a key means to reflect the digestion and metabolism of nutrients by animal organisms, evaluate the nutritional value of feed, and obtain important parameters of feed raw material nutrition. It has a very important guiding role in scientific research, production practice and feed formula design. The accuracy of the experimental results has very important economic significance and ecological benefits for saving feed costs and improving feed n...
