Palaguta A. Efficiency of growing and fatten pigs depending on technological acceptance feeding stern and provision of water

Feed-conversion efficiency of pig management subject to fattening methods & water supply. Reference paper. The object of the investigation is as follows, namely: feeders, water, waterers, working time of the operator, weaned pigs, Welsh, behavior, environmentally-controlled buildings, pork. The subject of the investigation is as follows: constructive peculiarities of the feeders, fattening rate, feeding & water losses, average-daily live weight gain, sexual behavior, expenditures of labor-power of the operator, animal welfare, carcass weight, qualitative characteristic of pork, performance data. The methods of the investigation. Conventional methods were utilized by the research execution. They are as follows: measurement, timing, weighting, chemical analysis, calculations, accountancy data, mathematical methods. Scientific innovation. For the first time in Ukraine new fattening methods of castrated boars have been elaborated & farm tests have been executed. Continuous & hopper feeders were used by constant fodder & water supply. Technological advantages & shortcomings were defined via this method implementation. "Universal" type feeder proved to be applied by both life cycle feeding of the gilts & their market fattening up to 110 kg LWG. Nipple waterers are recommended to be installed near the feeder by dry-mash feeding. The nipple waterer height is defined. Various shape bottoms are adjusted to the feeders. They are supplied with the carrier drains for waste disposal off the limits of the feeding stalls. Practical implementation. Working time of the operator is saved by the "Universal" type feeder utilization during management & feeding of the pigs. Feeding losses are lowered & feeding stalls are applied during weaning & keeping of the gilts. Intensive fattening is implemented up to 110 kg LWG without feeding trough change. New technology application resulted in production performance increase by 7-18 %. Labor expenditures of the operator were abated per 10,6 %. Feeding & water losses were 2,5-fold decreased compared with the conventional technology implementation.
