The system is suitable for feeding sows at different growth stages;
when the sow enters the feeding station, the temperature measuring sensor collects the body temperature information of the sow and transmits the collected body temperature information to the upper computer.
When the sows enter the feeding station, the weight scale collects the weight of the sows and transmits the collected weight and temperature information to the upper computer.
When a sow enters a feeding station, according to the identity information of the sow, a computer system is requested to identify whether the body temperature of the sow is abnormal or not through a communication system, whether the sow is in a pregnancy isolated state or not is judged through an upper computer according to the sow growth stage uploaded by a setting module, whether the sow is in a pregnancy isolated state or not is identified through calculating the nonpregnant days of the sow, whether the sow is in an oestrous state or not is identified through the feeding condition of the sow on the last day, the spraying module is controlled to perform corresponding processing according to the actual condition, different colors are sprayed according to early warning categories, the convenience is brought to the identification of a breeder, and corresponding measures are taken. The water supply module supplies water according to the feeding condition, so that the sows can feed conveniently.
The different growth stages of the sow are generally divided into three states (namely, feeding states) of a nonpregnant period, a gestation period and a lactation period, and the feed intake of the sow in different feeding states is different; maximum feed = basic feed + adjusted pregnancy/adjusted lactation/adjusted nonpregnant + adjusted temporary (maximum feed-already fed on previous day); the feeding amount of the sow is adjusted according to different growth stages of the sow.
Basic feeding amount: according to different feeding states of each sow, the sow requires that the body of the sow is fat or thin for good birth and good care in a certain growth stage, the feeding amount of the sow needs to be adjusted, if the sow needs to be fat, the feeding amount is increased, and if the sow needs to be thin, the feeding amount is reduced. The basic amount of the feed state of the feed is set every day.
Pregnancy adjustment amount: the number of pregnancies of each sow is different, and the food intake is also different. Meanwhile, when the sows enter the gestation period, the feeding targets of the pregnant sows are piglets which are strong in head number, heavy in birth, uniform in individual and strong in activity and are produced by the sows. To achieve this goal we need to adjust the amount of feed to pregnant sows over a certain period of time.
Adjustment amount in lactation: according to the farrowing time of the sow, when the sow enters a lactation period, the feeding amount of the sow in the lactation period is increased by a plurality of grams on the original basis when the sow is in a certain time period in the stage day age.
Adjustment amount during non-pregnancy: according to the later weaning time of the sows in the lactation period, whether the sows enter the nonpregnant period or not is judged, and the feeding amount of a certain time period needs to be adjusted in the nonpregnant period.
Temporary adjustment amount: for some reasons, such as sow sickness, sow shelf life and the like, the actual daily feeding amount of some sows is less than the specified normal feeding amount. According to the daily feeding record of each sow, all sows with feeding residual amounts larger than a certain numerical value are counted and summarized according to feeding information such as the feeding state and the feeding residual amount of the sows, the feeding amount of the sows in the next day is compensated and adjusted, and the compensation amount only plays a role in the next day.
The daily feeding amount of each sow comprises the following parts: feeding basic amount + (gestational period adjustment amount, lactation period adjustment amount, non-pregnancy period adjustment amount) + temporary amount adjustment amount. The daily feeding total amount of each sow is equal to: feeding amount + residual feeding amount; the total number of times of daily feeding of each sow is equal to: number of meals + remaining number.
A feeding station is arranged on each feeding column in the sow feeding system. Each sow wears an electronic ear tag, and by utilizing the electronic ear tags, the wireless ear tag collector 1 of the feeding station system identifies individual information according to the mark number of the sow wearing the electronic ear tags and correspondingly processes the individuals.
When a sow wearing the electronic ear tag enters the feeding station for feeding, the electronic ear tag reader of the feeding station reads the electronic ear tag number of the sow, the feeding state, the daily feeding total amount, the daily feeding amount, the remaining feeding amount of the sow, the daily feeding total times, the daily feeding times, the remaining times and other information are obtained through the electronic ear tag number of the sow, the time when the sow enters the feeding station is recorded, and the time when the sow exits the feeding station is recorded.
The feeding process is as follows:
(1) If the residual feeding amount is 0, the batch feeder does not feed;
(2) If the time interval between the two times of feeding is controlled and the time interval between the current time and the last time of feeding is smaller than the time interval between the two times of feeding, the feeding machine does not feed;
(3) If the residual feeding amount is more than 0, controlling the time interval of two times of feeding, wherein the time interval between the current time and the last feeding time is more than the time interval of two times of feeding; or the time interval between two times of feeding is not controlled; the batch feeder starts to feed when working;
(4) If the percentage of the feed amount fed each time is controlled, when the feed amount is less than the specified percentage of the feed amount every day, the feeder feeds; otherwise, stopping feeding by the feeder;
(5) When the feeding machine feeds, whether the sows are at the feeding station is detected, and if the sows do not feed, the sows leave the feeding station, and the feeding machine stops feeding;
(6) When the batch feeder feeds, simultaneously detecting whether the feed in the trough is in the upper limit range of the trough capacity, if the feed exceeds the upper limit of the trough capacity, suspending the batch feeding by the batch feeder until the weight of the feed in the trough is lower than the lower limit of the trough capacity, and continuing the batch feeding by the batch feeder;
(7) When the sow withdraws from the feeding station, the weight of the withdrawing back trough is recorded, and the feed intake of the time is equal to: the feeding amount of the time (the weight of the sow exiting the back trough-the weight of the sow entering the front trough).
The sow feeding algorithm utilizes the technologies of RFID, infrared technology, temperature and weight measuring and other sensors, computers, networks, machine vision learning and the like, and accurately sets the daily feeding amount and feeding times of each sow according to the characteristics of difference of the feed intake amount of each sow in different growth time; the method is characterized in that the actual feeding amount, feeding time, feeding times, time of entering and exiting a feeding station, weight and other data of each time are recorded, a growth and development curve of the sows in production is calculated, the breeding of the sows is facilitated, the growth and development of the pigs are optimized through data analysis, the daily gain and feed energy conversion in the growth stage are optimized, and a new important feeding solution is provided for the breeding selection and breeding of the sows.
