Residual effect of inclusion of the entire raspa mandioca in diets úmidas dry or the period of nursery, further on performance of pigs

by Nogueira Junior, Francismá Gomes

Abstract (Summary)
Was used 32 castrated piglets of commercial lineage, weaned at 21 days old and approximately 6,0 kg live weight, with the objective of evaluating the effect of theinclusion of different levels of dried cassava root meal (0, 12, 24 and 36% of DCRM)and feed forms on the performance of piglets in the initial phase (21 to 70 days) and its residual effects on the phases of growth, termination, total period and the 90 kg slaughtering age. The experimental design used were randomized blocks in afactorial scheme 4 x 2 (four levels of inclusion of DCRM and two feed forms dried and wet diets) with four replications by treatment, being the experimental unit one animal. The criteria used for the block formation was the initial piglets weight. The daily average weight gain (DMWG), daily average fees intake (DMFI) and the feedsconversion (FC) weren?t affect significantly (Pgt; 0,05) by inclusion of different levels of DCRM of dry or wet diets. It was concluded that independent of the feed forms of theintegral cassava scrap can be used in rations for piglets in the day-care center phase until the level of 36% without compromising the zootecnic performance between thedifferent phases and the 90 kg slaughtering age of live weight.
