Total pig and sow numbers continue to rise in China, while the decline in US breeding pig population may be less dramatic than forecast. One of the authors of the latest NRC ‘Nutrient Requirements of Swine’ explains what has been updated in the latest edition. More than eight out of 10 Spanish pig farms will comply with the EU sow stall ban by the 1 January deadline, it is reported.
China is the pork powerhouse of the world with over 51% of the world’s population of pigs raised there, according to Ron Lane, senior consultant for Genesus in China.
Looking at the size of the breakdown of the inventory for August 2012, breeding stock was around 49.74 million and total on farm inventory was around 464.90 million (as compared to July 2012 breeding stock was around 49.54 million and total on-farm inventory was around 460.75 million). These figures represent increases of 1.8% and 3.1% for the total and sow populations, respectively.
Profit margins continue to show declining returns and many farmers say they are just breaking even.
Since 2001, large specialized and/or commercial farms have been rapidly increasing in market pig production in China, contrasting with the formerly largest production base from the backyard farms. Backyard production has dropped from 74% of total hog production in 2001 down to 37% in 2011, according to Mr Lane, citing a report from Rabobank International.
To promote the development of its agricultural sector, China invested more than six trillion yuan (CNY; US$930 billion) during the decade from 2003 to 2012, the highest in the country’s history.
The recently published 11th Revised Edition of the Swine NRC was given much consideration at the Latin American Animal Nutrition Congress (CLANA) in Puerto Vallarta, Mexico.
Dr Lee Southern, Professor Emeritus of the School of Animal Sciences at Louisiana State University in the US presented the committee’s work.
“The National Research Council (NRC) is an arm of the National Academy of Sciences. It publishes for any species of animals. It calls itself an unbiased source. It can only use peer-reviewed published literature.
“If there was no published data or change, we didn’t make a change. The vitamin information is exactly the same as in 1998. There have been no new published papers on vitamin content in feed ingredients,” added Dr Southern.
