| dc.description.abstract | In several laboratories at ESPOCH, if evaluated three methods of saponification
(NaOH, KOH y Ca(OH)2) on two types of fat (SO and RAP), these were designed
to feed dairy cows. It applied a Completely Design at Random with factorial
arrangement 3 x 2 and 3 repetitions for treatment. The RAP before being
saponifiedwere filtered for 24 hours and the SO was diluted to 121 ºC. The
filtration of RAP allowed greater concentration of MS (24,76%), fat (69,51%) and
fiber (10,66%) reducing protein (1,46%) and minerals (5,01%). The dilution of SO,
allowed greater concentration of MS (99,07%), fat (96,81%), and protein (5,79%) it
observed a decrease of minerals (0,061%). The profile Fatty Acids showed higher
concentration of unsaturated in RAP (50.7%) and lower in SO (39,84%). The
soaps made with Ca(OH)2 in SO and RAP , allowed greater concentration of MS
(92,98%), (82,89%), minerals (17,67%; 12,13%) and fat (78,67%; 85,98%) with
lower values compared to the other treatments in protein (1,81% y 1,87%) and
fiber (1,20% and 0,0%). The total solubility (pepsin pancreatin analysis) of soaps
RAP were lower (89,33%) compared to those made with SO (95,27%).The B/C
was higher in soaps made with Ca(OH)2 in RAP (1,71). It concluded that the
soaps of Ca(OH)2 were the most profitable, better consistency and better
protected from ruminal degradation, so it is recommended further study of
solubility (in vitro) and (in vivo) and then to prove the nutritional and reproductive
effects on dairy cows. | |
