Genetic Improvements
Exist even today in day many producers who, for various reasons, continue their crosses on the farm in order to produce his own maternal autoreemplazo and also the paternal line, however this temple as it is not recommended since there are many years commercial houses that are dedicated to the development of lines genetic improved to obtain high productivity. Farm or the producer to not yet be benefiting from these improvements and progress should take as a first step a boar terminal acquisition to immediately improve the performance of its pigs for fattening. Benefits are relatively quick, being able to observe an improvement since a good male characteristics are the following: yields specific that should be expected in pigs for fattening are the following: weight greater than 104 kilos at 154 days of age mean gain of more than 750 grams per day weight no greater than 2.40 feed conversion index Backfat (mm) 10 to 12 milimteros economic analysis: The market price of a male that transmit their offspring characteristics before mentioned oscillates between thousand and thousand five hundred dollars, if only we take the value of the Stallion how we can perhaps make the following economic analysis: the time of life that we are going to give to the boar on the farm is two years, which is the same to say 104 weeks, if we started to use the 35 weeks of age that is recommendedwith artificial insemination at a rate of two collections per week you will obtain 208 collections in the life of the boar. Now either the average dose per collection at a concentration of 3.5 trillion by weekly doses of 100 ml 20 dose per collection is, if multiply you this value by 208 collections, we get an average of 4,160 seminal doses during the life of the Stallion. If we apply 3 seminal doses by cerda, we will obtain 1386 sows inseminated, with artificial insemination can obtain a fertility rate of 90%, which means 1386 inseminated bristles reach childbirth 1248 bristles.
1248 Paridas bristles get a minimum of 9.5 piglets weaned per sow, which gives as a result the production of 11,856 pigs for fattening, of They estimated that 95% arrive until the age of sale, which is equal to 11263 pigs. If we divide the value of the boar (US$ 1,500) between 11,263 pigs that has potential of producri gives us 13 cents of dollar per each produced pork. If we think it’s expensive to invest 13 cents for each pig that we will get to the market, having the potential to considerably increase productivity through a better weight gain and efficiency in feed conversion, it is time that we reflect if we are being consistent with reality and what we want for the farm..
