THE INFLUENCE OF PRESTARTER FORAGE QUALITY ON PERFORMANCES AND ECONOMICAL EFICIENCY OF GROWING PIGLETS

M. Alda, D. Drinceanu, C. Julean

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%.

Key words: mash feed, pellet feed, ad libidum feeding, diet feeding, post weaing crisis

Rezumat
Într-un experiment efectuat pe 520 purcei sugari, proveniti de la 52 scroafe, s-au stabilit indicatorii de performanta si economici la doua variante de furajare astfel:V1 – 259 purcei hraniti cu nutret combinat cu parametrii cunoscuti, sub forma de faina, R.01 care s-a administrat între 10 – 57 zile. V2 – 261 purcei hraniti cu 2 tipuri de furaje combinate granulate: furaj prestarter TS 8001 între 10 – 42 zile si furaj prestarter TS 8063 între 43 – 57 zile. Purceii din V1 care au consumat nutret combinat R.01 au înregistrat un consum mai mare de furaj pâna la vârsta de 32 zile, însa cu manifestarea fenomenelor crizei de întarcare, remediata prin furajare restrictionata. Purceii din V2 înregistreaza un consum mai redus de nutret granulat si fara fenomenele crizei de întarcare. Pe perioada experientei (1-57zile) purceii din V2 realizeaza un smz de 177 g /cap /zi iar cei din V1 realizeaza doar 165 g /cap /zi. În aceeasi perioada la V2 s-a constatat cu 2,62% pierderi mai putine fata de V1, diferenta fiind nesemnificativa. Cheltuielile cu furajarea au fost de 83027 ROL/cap la V1 si 139163 ROL/cap la V2, adica cu 59,66% mai mari. Apreciem ca furajele granulate sunt mai bine acceptate de tubul digestiv al purceilor, elimina simptomatologia crizei de întarcare dar cheltuielile cu furajele cresc cu cca. 60%.
