Abstract
In an experiment made on 520 piglets, from 52 sows, were established the performance and economical indices for two experimental groups: V1 259 piglets fed with combined forage with known parameters, meal type, R.01, which was administered for 10-57 days; V2 261 piglet fed with two types of granulated forage: prestarter forage TS 8001 which was administered for 10-42 days and prestarter forage TS 8063 administered from 43 to 57 day. Piglet from experimental group V1 fed with combined forage R.01 have registered a greater forage consumption until 32 days of age, but when the weaning crisis appeared were remediated by forage restriction. Piglet from V2 registered smaller forage consumption of granulated forage and without weaning crisis. On entire experimental period (1-57 days) piglet from V2 registered a daily weight gain of 177 g/head/day and piglet from V1 registered a daily weight gain of 165 g/head/day. In the same period at V2 were registered wastage with 2.62% smaller comparative with V1, but the difference was insignificant. The forage cost was 83027 ROL/head at V1 and 139163 ROL/head at V2, with 59.66% greater. We estimate that the granulated forage have better tolerance in piglet digestive system and eliminate the weaning crisis but the forage cost rises with 60%.
