COMPARISON OF THE PRESERVATION OF PIGLETS AND INTENSITY OF THEIR GROWTH IN THE PERIOD OF REARING AT DIFFERENT WAYS OF AIR GIVING AND AIR REMOVAL
Journal Title: Наукові доповіді НУБіП України - Year 2017, Vol 4, Issue 4
Abstract
The researches were carried out under conditions of the high technological industrial pig breeding enterprise OOO ”Demis-Agro”. It has been determined that independently on a season of a year in the premise with lower air giving the growth intensity of piglets was probably (P < 0.001) higher than in premises with the system of a side air giving through the wall valves. It has been determined that in premises with lower air giving independently on a season of a year the level of dust and bacteriological pollution and the contain of harmful gases are lower than in premises where air to animals was given through the side wall valves. It is noticed, that higher average daily gains in the first premise are as the result of more effective aligning of daily and average annual temperature and air cleaning from harmful admixtures (dust, bacterium, ammonia, hydrogen sulphide) at using the effective system of air exchange with lower air giving and its previous thermal preparation. The average daily gain of piglets during a year in the first premise changed from 330.15±1.49 (in summer)to 535.00±2.12 (in autumn), while in the second premise it changed from 270.04±2.20 (in summer) to 500.00±2.11 (in autumn).
