Embodiment 1

[0020] according to figure 1 As shown, the litter box body 1 is a closed box structure with a length of 31 cm, a width of 28 cm, and a height of 40 cm; a transverse partition 4 is provided in the middle of the litter box body 1 to divide it into an upper litter box 3 and a lower litter box 5 The double-layer litter box structure, the upper nest box 3 is provided with an access hole 2; the lower edge of the access hole 2 is 16cm from the bottom, and the diameter is 14cm; Hole 6 in the nest, hole 6 in the nest is 14cm in diameter.

[0021] The advantages of the present invention are shown by the following different factor tests carried out under the same conditions

[0022] The litter box that participated in the test was made of wood, and the structure is as follows:

[0023] The length, width and height of the litter box in group A are 31cm, 28cm and 40cm respectively, the diameter of the hole is 14cm, the lower edge is 16cm from the bottom, and the horizontal direction i...

Embodiment 3

[0044] Effects of different litter environments on mink behavior and production performance of 28-45-day-old mink

[0045] Test animals were from Study One. Six litters of 1-day-old mink were selected from groups AB, AC, AD, and A respectively. The number and date of birth of minks in each group were roughly the same, and the number of minks was 4-6, and the difference in date of birth was within 2 days, and there was no significant difference between groups (P>0.05). The experimental animals for late-lactation behavior sampling were the experimental animals in the late-lactation stage of Research No. 1, that is, the young minks in the litter were 28 days old and above, and the number of litters in each group was between 14 and 16 litters.

[0046] When the young minks were 28 days old, the bowl-shaped artificial nest in AB and the partitions in group AC were removed, that is, group AB became group AB*, and group AC became group AC*. Other feeding and management were the sam...

Abstract

The invention provides a nest box beneficial to playing maternity of minks and increasing survival rate of young minks, wherein a transverse clapboard is arranged in the middle of a nest box body to form a double-layer nest box structure; an in / out hole is arranged on the upper layer of the next box; and an inner nest hole through which the minks enter the lower layer of nest box is arranged at the remote end of the transverse clapboard away from the in / out hole. Because the nest box is in the form of the vertical double-layer structure, the nest box is more beneficial to keeping warm of the lower layer of next box; the humidity fluctuation is low; the time for female minks to be outside the nest box is shortest; the death rate of the young minks which are 1-7 days old is lowest; the sanitary condition of the nest box is best; the time for the young minks which are 1 day old to be outside the nest box is shortest; the time for fetching the young minks which are 5 days old is shortest; and the death rate of the young minks which are 1-21 days old can be obviously reduced; and therefore, the culture benefit can be greatly increased.

Description

Technical field The [0001] The present invention provides a nest box that is conducive to the sexual play of mink and improvement of mink. It is a improvement of the existing mink nest box structure, especially in the field of animal breeding devices. Background technique: [0002] Newborn mink was born from late April to early May of each year, and is a typical late mammal.The development of the newborn marten has not been fully developed, the eyes have not opened, almost hairless and limited exercise capacity. The rectal temperature is only 77%of the adult female marten. The difference between individuals is large.The establishment of late mammals from birth to the constant temperature mechanism is a gradual process. During this period, there is often a stage of rapid development of body temperature adjustment.There are four main reasons for the poor heat production capacity of late mammalian: first, the development of the nerve regulation mechanism related to heat production ...
