Practical Application Of Data Intensive Management Of Efficient Farming In Large Scale Pig Farms

With the rapid development of China's aquaculture industry,the expansion of aqu aculture scale and the rapid improvement of production level,traditional breeding meth ods are no longer adapted to modern pig production,but gradually withdraw from the stage of history and replace with healthy and efficient breeding methods under the dig ital management.In order to explore the role of data management in improving the per formance of pig farms,we used the pig networking system of Beijing nongxin interco nnection to carry out the practical application of data management on my own pig f arms.Us by setting up the sow of weaned piglets number(PSY),sow turnover,comm ercial activity three goals,raise farm per sow in such number of pig(MSY),for the related factors affecting these indicators,and in the process of production management conducted a series of improvement measures for the problems,and production levels i ncreased significantly,periodic progress has been made.First,relevant factors affecting pig farm production performance were investigated.Based on the results of the investi gation,reasons for the pig farm production performance were found.Then,the directio n of adjustment was determined,and the serialized breeding management plan was for mulated,optimized and implemented.In the PSY target enhancement test,we mainly conducted the practice and explor ation of semen quality analysis and improvement of boar,standard feeding procedures for sows,reduction of stillbirth rate,periodic analysis of fetal secondary structure and selection of reserve sows,and analysis and adjustment of relationship between birth w eight of piglets and feeding amount of sows in pregnancy.The analysis results show th at there is a trend of positive proportion between the total weight of newborn piglets at birth and the feeding amount of pregnant sows at the second trimester.By comparin g the results of PSY and the survival rate of the delivery room from 2013 to 2017,t he two indicators have been on an upward trend in the last five years,indicating that the experiment measures of weaning piglets in pig farms are effective.We mainly carried out the practice and exploration of dynamic adjustment of bac k fat of sow,analysis and reduction of regrow rate of sow,analysis and adjustment o f sows elimination,proportion analysis of estrus within 7 days and control of key points of weaning sows management.According to the statistical analysis of the annual up date rate,knockout rate and mortality rate of sows from 2013 to 2017,except the hig h update rate in 2013(the proportion of newly built sows in pig farms is high),the annual update rate from 2014 to 2017 is about 30%,which reaches a good update lev el of sows.The annual mortality rate of sow presents a relative decline.In addition,we found that within the range of 8-15 mm back fat,the better the back fat of the sow,t he shorter the estrus time after weaning,and the higher the estrus proportion within 7days.This result provided certain reference value for the key points of weaning sows management.From 2013 to 2017,the rate of oestrous breeding of weaned sows within7 days showed a gradual upward trend.In 2017,the highest rate in the last five year s was 85.07%,which was 19.48% higher than that in 2013.Overall,the rate of childbi rth increased from 2013 to 2017,which was 90.8%,the highest in nearly five years.In the test of improving the survival rate of commercial pigs,we mainly carried out the practice and exploration in several aspects,such as weaning weight,feeding q uantity analysis in the delivery room,standardized operation of foster care in the deliv ery room,nursing scheme for the care of weak babies,disease monitoring and prevent ion and control,and raising environment monitoring and improvement.Through analysi s,it was found that low sows intake was the key factor affecting the weight of wean ed piglets in the field.The pig herds at all stages had certain immune status defects.After adjustment and optimization of immune procedures,the immune status of the pi g farms was gradually improved,and the disease prevention and control ability was gr adually enhanced.Through the practice and application of digitized management of efficient and hea lthy pig breeding in pig farms from 2015 to 2017 and the improvement of production indexes,PSY,sow turnover,commercial pig survival rate,MSY and whole-process fee d meat ratio of pig farms have been greatly improved,and the digital record of the c hange process of pig production performance from unideal to excellent.This experiment has some reference value for the data management of large-scale pig farms.
