Description

A metabolic cage for laying hens

technical field

The utility model relates to a breeding cage, in particular to a metabolic cage for laying hens.

Background technique

Metabolism test is a key means to evaluate the nutritional value of feed and obtain important nutritional parameters of feed raw materials, and it has a very important guiding role in scientific research, production practice and feed formula design. The accuracy of metabolic test results has very important economic and ecological benefits for saving feed costs and improving feed nutrient utilization. Since Sibbaid (1976) put forward the chicken true metabolizable energy determination scheme, the use of force feeding and anus suture to collect feces has played an important role in the determination of poultry metabolizable energy and nutrient utilization. However, since laying hens still lay eggs during the metabolic test, the method of anus suturing is not suitable for laying hens, and laying hens are often used to eat freely and directly collect excreta for metabolic tests. Because the feeding trough and the water tank are in the same direction and the height is too low in the current metabolic cage, the laying hens drink water while eating, resulting in feed contamination and some feed entering the drinking water. When the chicken pecks, the feed is scattered, causing feed intake The amount cannot be accurately recorded; the feed is scattered in the manure collection pan, and due to the large space for activities, when laying hens defecate, they often discharge the manure on the feed, polluting the manure. The pollution of excrement is serious, and the experimental operation is difficult. In order to ensure the accuracy of the measurement results, special requirements are required for the metabolic cages of laying hens. The utility model separates feeding and drinking, adopts a convenient nipple-type drinking water line, increases the depth of the trough, and reduces the loss of feed; a movable isolation net is added in the cage body to reduce the activity space of the laying hens, and collect the feces. The tray is divided into two parts to reduce the pollution of the feces from the feed; the width of the bottom mesh of the cage is increased to facilitate the dropping of the feces into the feces collection tray to ensure the accuracy of feces collection; after changing the cage door to the cage body Side, convenient for experimental operation.

Utility model content

In order to overcome the shortcomings of the existing metabolic cages, the utility model provides a metabolic cage for laying hens through a mobile isolation net.

The technical solution adopted by the utility model to solve the technical problem is: a metabolic cage for laying hens, including a cage body, a cage door, a trough, and a manure collection tray, and the cage body is provided with an isolation net that can translate forward and backward. , the grid gap of the isolation net is 5.5cm; the front side of the cage is hung with a trough; the top of the rear side of the cage is provided with a nipple drinking line; part; the cage door is located in the middle of the rear side of the cage.

Separate feeding and drinking water, adopt convenient nipple-type drinking water line, increase the depth of trough, and reduce the loss of feed; add movable isolation nets in the cage to reduce the activity space of laying hens, and separate the manure collection tray into Two parts to reduce the pollution of feces from feed; increase the width of the bottom mesh of the cage to facilitate the dropping of feces into the feces collection tray and ensure the accuracy of feces collection; change the cage door to the rear side of the cage for convenience Experimental operation.

The utility model has the beneficial effects of reducing the loss of the feed and the pollution of the excrement by the feed, ensuring the accuracy of the measurement results and facilitating the operation of the experimenter.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, a metabolic cage for laying hens comprises a cage body 1, a cage door 2, a trough 3, and a feces collection tray 4, and the cage body 1 is provided with an isolation net 6 that can translate forward and backward. The grid gap of isolation net 6 is 5.5cm; Cage body 1 front side is hung with material trough 3; Cage body 1 rear side top is provided with nipple type drinking water line 7; The feces tray 4 is divided into two parts; the cage door 2 is located in the middle of the rear side of the cage body 1 .

Feed chute 3 is a right-angled trapezoid; Its length is 35cm, the width of the bottom is 5cm, the height of the inner side is 5cm, the height of the outer hypotenuse is 18cm, and the height of both sides is 12cm.

The feces collecting tray 4 is trapezoidal; the length and width of the upper opening are 70cm and 40cm respectively, and the height is 4cm, and the length and width of the lower bottom are 66cm and 37cm respectively.

The metabolic cages for laying hens are made of stainless steel.

The cage body 1 is made into a cuboid whose length, width and height are respectively 50cm, 37cm and 32cm. The grid gap at the bottom, both sides and the rear side is 2cm, and the top grid gap is 4cm. The same grid gap is 5.5cm, and the front side grid has a horizontal grid apart from the bottom 5cm, which is convenient to the trough 3 suspension.

Select the laying hen in the laying period, put the laying hen into the cage body 1 through the cage door 2, feed the laying hen through the trough 3, and freely drink water through the nipple drinking line 7. At the beginning of the formal metabolic test, after the laying hens eat food, the isolation net 6 provided at the front end of the cage body 1 is moved 12 cm into the cage to block it, so as to reduce the activity space of the laying hens. The width of grid, its width is 2cm, makes its defecation relatively concentrate and falls in the excrement collection tray 4, guarantees the accuracy of excrement collection; Divided into two parts to reduce feed scatter and waste when laying hens eat, and not cause feed to feces pollution. A cage door 2 is arranged on the rear side of the cage body 1, and the cage door 2 is 31 cm long and 20 cm wide, which is convenient for experimental operation. The utility model has ingenious design, scientific feeding and convenient operation.

The specific implementation of the utility model has been described above in conjunction with the accompanying drawings. Obviously, the utility model is not limited thereto, and various modifications within the scope of the utility model are within the scope of protection of the utility model.
