A simple linear trend was used to predict pigs per litter for each year. The annual growth rate in pigs per litter was 0. This may seem small, however, over the year period, this equates to 2.
Production performance, measured using pigs per litter, has been particularly strong in the last few months. For the first and second quarters of , pigs per litter averaged In August in , the latest month for which data is available, pigs per litter was In contrast, the predicted number of pigs per litter for using the model referenced above, was only If pigs per litter for the remaining months in average 11 pigs per litter, would be one of the best years in terms of improvements in production performance over the last three decades.
Improvements in production performance, such as litters per sow per year and pigs per litter, have impacts on the number of sows needed to supply the domestic and export markets. Obviously, if pigs per litter had not increased over the last few decades, we would need a much larger sow herd.
Among the non-infectious causes are: absence of uterine space, stress, seasonality, number of parities, etc. Porto Alegre, Thanks for the education. From all I gathered it means from the 4th parity the sow should be culled except you feel she is still going to give you good litter again.
It also means depending on the prevailing factors observed a sow can produce up 10 litters. Thanks so much for these submission am also a farmer in the same industry and l h have learnt that a pig reaches its peak on the fourth parity. My challenge is my does Farrow agood number of piglets but smush almost 50percent. Your email address will not be published. This site uses Akismet to reduce spam.

Abstract Background The objective of this study was to underline that litter size as a key trait of sows needs new parameters to be evaluated and to target an individual optimum. Results The new traits for evaluating litter size were derived from the individual numbers of total born piglets TBP per parity: In most cases, sows reach their maximum litter size in their fourth parity.
Background In pig breeding, the number of piglets born alive per parity NBA is a trait of economically importance, but affected by multiple factors [ 1 ].
