Next to reproductive failure, lameness is the second most common cause of sows being culled. Lameness is the most common cause for individual treatments with antibiotics in piglets and growing pigs. The intestines control the rates of absorption both into the body and skeleton and these are necessary to maintain an equilibrium between demand and excretion. Lameness detection in electronic sow feeding (ESF) systems is more difficult and lame sows are often missed until they reach the point where they are missing meals. Lame pigs and especially those with claw injuries (e.g. On necropsy, lesions are restricted to the joints, especially the stifles, and include an excess of clear, yellow synovial fluid that … Movement is difficult and lame pigs rest frequently, find difficulty in rising and are … Non-slip flooring: Non-slip flooring will help to prevent injuries.

The pain associated with lameness can make it difficult for pigs to walk to feeding and water troughs, which in turn would have a negative impact on their growth rate, their welfare and cause stress that renders them more susceptible to diseases. It is important to remember that lame sows will tend to move better immediately after weaning when their body condition is lighter so this is not a good time to diagnose lameness in the sow herd. Video and audio recordings of the webinar are available here. Research shows that narrower voids between slats (≤18mm) and better hygiene (i.e. - Trauma (from sow) - Trauma from abrasive surfaces (24 hrs post farrow). Lameness in breeding swine can result in the following: 1) higher rate of breeding stock replacement with attendant increased risk of disease introduction; 2) an inability to maintain a breeding schedule due to an unreliable pool of breeding pigs and, ultimately, an impact on pig flow in the grower/finisher area; 3) increased cost of maintaining additional breeding stock; 4) poorer reproductive performance due to … In this study, the prevalence of lameness in sows was estimated using data from 76 pig breeding units in England and risk factors associated with the occurrence of lameness were examined. If lameness involves the foot look closely at floor surfaces. Hence, incorporating routine claw inspections into the management programme for breeding sows is an essential first step in addressing lameness. Leg conditions in young and growing pigs . Lameness can account for significant losses in growing pigs either because the pigs are unfit to travel on welfare grounds and require to be destroyed, or they are part or totally condemned at slaughter. Create. Nowhere is this relationship more evident than in the case of the finisher pig, where the authors' research identified a clear positive relationship between growth rate and lameness; that is to say that by selecting pigs for fast growth rate, we are contributing to the problem of lameness in these animals. Home / Methods for preventing lameness in pigs. Awareness of lameness in the sow herd has to start with an assessment of reasons for culling sows, and sow replacement and mortality rates. tetracycline, or dusted with an antibiotic wound powder. zinc, copper and manganese) reduce claw lesions in group-housed gilts, Slowing the growth rate of replacement gilts reduces the severity of joint lesions. Combining these features in a specially formulated 'developer diet' for replacement gilts could improve sow productivity and longevity. From the piglet to the mature pig, to the fit pig to the obese pig, arthritis is an equal opportunity disease – no pigs are immune and any can be stricken with this painful condition at any time. If there is a high incidence of leg sores associated with fractures assess the conditions precipitating leg weakness. What are 5 conditions causing lameness in neonatal pigs? Detecting sows in the earlier stages of lameness - at which time, they are more likely to respond to treatment - requires a more specific lameness protocol or locomotion scoring system. This is worrying considering that levels of lameness are often very high in such systems because of constant re-mixing on slatted floors. Trace mineral supplements specially designed for claw health (i.e. It is important to note whether sows/gilts being culled for reproductive/poor performance are also lame and to start recording the number of sows with obvious clinical problems such as missing dew claws or external abscesses on their limbs. The ratio of calcium to phosphorus in the diet is also an important factor in this equation and this should not rise above 2:1, when it does the absorption of calcium may be impaired, likewise if the ratio drops below 1:1. Not all lameness can be prevented, but precautions can be taken to prevent the dreaded problem. Foot-and-mouth disease and the vesicular diseases are discussed in chapter 12. Improve feed efficiency and eliminate waste with the original, mechanical-flow, automatic feeder, with models available for pigs from wean to market. Feet First ® Swine Lameness Prevention When a sow is lame, it leads to lower feed intake (especially during lactation), decreased reproductive performance and ultimately an early exit from the herd. In the maiden gilt or during the first pregnancy infectious lameness is usually due to erysipelas, glässers disease, mycoplasma infections and brucellosis in those countries where it is endemic. Provided that gilts/sows are not over-stocked, severe lameness is relatively easy to detect in any group system but especially those in which sows are fed simultaneously at specific times of the day. Lame pigs have poor welfare because they are in pain. Lameness can present with a … In the pig it is difficult to examine their feet.

The use of slatted steel (Tribar) type flooring in the farrowing crate should be avoided as it is not only detrimental to the claw health of sows but is also a major risk factor for limb and claw lesions in piglets. Lameness is a major production disease of pigs and threatens the sustainability of current pig production methods due to its high prevalence and its detrimental impact on profitability. If the acute form of the disease affects nursery pigs and is not treated appropriately, the subsequent progression of the disease to the chronic form is seen in the grower/finisher pigs. The surface of exposed, cleaned lesions may be sprayed with antibiotic, e.g. Mycoplasma arthritis caused by Mycoplasma hyosynoviae affects growers to young adults.
