High profitability of pig farming only if the building is prepared to isolate the animals from external weather conditions.
A piggery should maintain the highest possible temperature stability, both throughout the day and throughout the year, especially in autumn and winter. Reduced heating in that period could undo the efforts and funds spent on preparing high quality feed and pig healthcare. It is possible, however, to reduce heating costs efficiently, using the best THERMANO AGRO insulation.
An equally important task is to ensure the optimum temperature in summer and to protect the animals from overheating. At excessive piggery temperatures, pigs eat less feed and gain weight slower: for each 1°C above the optimum temperature, feed intake is 1–2% less and the growth rate is 3% slower. At high ambient temperatures, pigs are prone to heat balance disruption, excessive body heat increase and overheating. High temperatures causes increased breathing rate and excessive secretion of urine and saliva. Thermal stress lowers the production and reduces reproductive activity in animals. In sows and gilts, thermal stress disrupts the hormone balance, causing the so-called seasonal summer infertility. In farrowing sows, causes reduced appetite, lowers milking yield and changes milk composition – it has an adverse impact on body weight gain and growth in reared piglets.
Another essential factor in piggery design is the necessity to maintain proper, high air humidity. The lack or poor quality of external wall insulation causes humidity condensation on cold surfaces (dew point). In winter even wall and ceiling frosting or freezing could occur, which inevitably leads to their destruction. Another adverse effect of piggery wall moisture is bacterial growth, which causes diseases in animals.
