Growth intensity and fattening qualities of pigs during changes in feeding types during reproduction and fattening

The article presents the results of studying dependence fattening qualities pigs on type feeding during rearing and its change these two periods. It is proved that dynamics pig growth depended changes. In first third experiment, live weight piglets with liquid was added more intensively. second experiment (70–120 days) animals same were characterized by intensive compared to analogues in which changed alternative. final fattening, this trend persisted. determined best throughout demonstrated constant feeding, worst changes dry feeding. Animals types grew intensively their counterparts, found had average 6.1 % higher daily absolute 2.4 relative gains, 4.4 at end rearing. Pigs consumed 11.5 feed per head day, but a 5.1 worse payment increments 1.0 piglet survival period. from negatively affected pigs. period prevailed variable preservation 0.5 %, gains 9.0 7.3 %. reached commodity 120 kg 7.2 days (4.3 %) faster, ate 4.3 better conversion an 18.4 complex index qualities. indicators while when changing fattening. for whole research advantages over analogues, gain 6.6 6.3 2.7 conversion. dynamics, hybrid English origin, rate exceeded most significant deterioration occurred
