In addition to this, the feed has antibiotics and hormones routinely added to it to increase the size of the pigs and the amount of pigs that can be sold as meat. The incorrect feeding of pigs actually increases their need for antibiotics due to the health issues that arise. Legally the pig’s feed can contain the hair, skin, blood, intestines and hooves of other dead animals. Pigs are often still fed dead pig carcasses and even dead cow carcasses. Free range pigs which are fed their natural diet may grow a bit slower and be leaner than factory farmed pigs, but at the end of the day this is actually a benefit to the consumer who will be eating meat of a better fat and protein composition.
Constant antibiotic use in factory-farmed pigs leads to antibiotic-resistant ‘super bugs’. Antibiotics in factory-farming are also used to increase the growth of the pigs. Factory-farmed pigs are routinely given antibiotics to increase their weight and so the meat is not contaminated with any pathogens. Despite the use of antibiotics, factory-farmed pigs are actually incubators for pathogens. One study found that about half of Dutch pig farmers, and 39% of Dutch factory-farmed pigs, were carriers of MRSA.
In 2005 there were an estimated 20 incidents of MRSA per month in South African hospitals. Studies have suggested that grass-fed animals have higher levels of nutrients like vitamin A, D, E and K. More studies have been done on cattle than on pigs, but one can conclude that similar effects would occur on any farmed animal should it be allowed to live a healthy active life while eating its natural food source. Studies measuring the fatty acid content in the fat of wild pigs have shown that they tend to be higher in omega 6 fatty acids, perhaps due to their natural food source which sometimes contains nuts and acorns.

About 150 pigs, finished from 73kg liveweight on a low lysine:energy ration, have been monitored and feed use, weight gain and efficiency recorded. These results are being compared to 150 pigs finished on a commercial grower/finisher ration. MLC Stotfold figures suggest that pigs fed a low lysine ration should achieve daily liveweight gains of about 850g/day between 70 and 90kg, and 900g/day between 90 and 100kg. Easton Lodge results show tremendous variations in weight gain for individual pigs of between 83 and 1.15kg a pig a day for the low lysine ration. This compares to between 125g and 1.08kg a pig a day for the commercial grower/finisher ration.
Overall, average weight gains for boars fed the low lysine ration appear to be lower than those for the commercial grower/finisher ration at 740g/day versus 777g/day. Whereas MLC had two pigs of equal weight in a pen, under commercial conditions the average weight variation has been about 15kg a pig in pen groups of 19. The culmination of these factors may account for the wide variation in daily lw gains of individual pigs, believes Mr Renolds. They couldnt check whether a dominant pig was restricting access to the feed bin – that could also have been a factor. The units nutritionist, Caroline Bevan, has been discussing ration formulation with MLC pig scientist, Pinder Gill.
Pigs at Easton Lodge suffer various pneumonias and the next two sets of trial pigs will have been treated with an in-feed antibiotic to help control respiratory disease. • Final performance data from the trial will be known later this summer when farmers weekly will be discussing the results with MLC pig scientist, Dr Gill.
The History of Guinea Pigs
In the beginning…. The common guinea pig was first domesticated as early as 5000 BC for food by tribes in the Andes region of South America,some thousands of years after the domestication of the South American camelids. 500 BC to 500 AD that depict guinea pigs have been unearthed in archaeological. People of ancient Peru worshipped animals and often depicted the guinea pig in their art. In 1532, selective breeding resulted in many varieties of domestic guinea pigs, which form the basis for some of the modern domestic breeds. Traditions involving guinea pigs are numerous; they are exchanged as gifts, used in customary social and religious ceremonies, and frequently referenced in spoken metaphors.
Black guinea pigs are considered especially useful for diagnoses. Among the upper classes and royalty, including Queen Elizabeth I. The earliest known written account of the guinea pig dates from 1547, in a description of the animal from Santo Domingo. The guinea pig was first described in the West in 1554 by the Swiss. Imagine 16th century explorers arriving in south america and coming across Guinea Pigs, i am sure they would have been fascinated by their vocal language.
This is an amazing glimpse into the past and confirms the Guinea Pigs arrival in Great Britain and the start of their journey to become one of the nations favourite pets. A Guinea Pig skeleton has been discovered in an Elizabethan mansion in Surrey dating from the 16th century. Coming soon Beatrix Potter and her love for Guinea Pigs ……………..
