FIG. 2
[0001] This invention relates to the technical field of pig breeding, in particular to an
eco-friendly pigsty using fermentation bed to supplement temperature to serve pig
mother and piglet.
[0002] With the development of animal husbandry, the scale of pig raising witnesses
great increase, but how to improve sow farrowing rate and piglet survival rate has
become a difficult problem faced by farmers and breeding enterprises.
[0003] At present, most farms adopt a one-time weaning measure, which separates the
suckling sows and piglets at one time, and then raises said piglets separately; due to
the sudden separation from the sow and siblings, said piglets usually suffer from
weaning stress response under this breeding method thus reduce the survival rate of
said piglets.
[0004] On the other hand, large changes in the feeding environment of pregnant sows
from pregnancy to production and lactation can also easily cause the stress response
of said pregnant sows, which can lead to low litter rate and high stillbirth rate in
severe cases.
[0005] Third, in cold seasons (such as winter) or areas with low temperatures (such as
Northeast China), external environment is low in temperature, and strong heat is
needed to be provided to the pigsty during the breeding process, which consumes lot
of energy and thus improves breeding cost.
[0006] Therefore, the design and construction of an integrated pigsty for mothers and
piglets, while applying fermentation bed technology to sows and piglets breeding is of
great sustainable development significance to Chinese pig breeding industry; said
pigsty can provide suitable growth conditions for said sows and piglets.
[0007] This invention aims to provide familiar environmental conditions for female
pig in its pregnancy, childbirth to breastfeeding process; adjust heat produced by
fermentation bed to control temperature inside pigsty to provide suitable growth
conditions for pig mothers and piglets.
[0008] This invention provides an eco-friendly pigsty using fermentation bed to
supplement temperature to serve pig mother and piglet comprising fermentation bed,
gestation rooms, delivery rooms, nursery rooms, main body of pigsty consisting of
corridors and walls,

[0039] In the process of sows and piglets breeding inside the pigsty provided by this invention, breeding technician enters the first locker room (106) through the first locker room door (105), and puts on disinfected clothes; and then enters the second locker room (109) from the second locker room door (110), and change the disinfected clothes again; said technician enters the disinfection corridor (108) from the second locker room door (111); disinfect hands in disinfection pool (107); said technician enters the pigsty corridor (121) through the pigsty corridor door (112); along the pigsty corridor (121), said technician can feed and observe the female pigs or piglets inside the delivery, gestation or nursery rooms.
[0040] In addition, after the female pig becomes pregnant, it enters the pigsty corridor (121) through the pigsty door (125), and then enters the gestation room for breeding; before delivery, said pregnant female pig can enter the delivery room from the gestation room to familiarize themselves with the environment; after birth, piglets can also walk back and forth between the delivery room and the nursery room to lay the foundation for the formal entry into the nursery room; by making female pigs and piglets familiar with the feeding environment, the stress response of said female pigs and piglets to environmental changes can be reduced, thereby increasing the
farrowing rate and survival rate.
