Acerola seed meal (Malpighia emarginata) as a source of dietary fibre in starter piglet diets

Abstract

Three experiments were carried out to determine the nutritional value and the effect of acerola seed meal (ASM) for starter piglet diets on feed digestibility, nitrogen balance (NB), growth performance and blood metabolites. Twenty-four crossbred entire male piglets (21.07 ± 3.07 kg) were assigned to a digestibility assay (Exp. I) and distributed in a randomised block design (RBD) with two treatments composed of reference diet (RD) or test diet (20% replacement with ASM), 12 replications and with one pig per experimental unit (EU). An NB study (Exp. II) was conducted with four levels of ASM (0, 4, 8 and 12%) and 24 crossbred entire male piglets (20.78 ± 1.84 kg) allocated in an RBD of six replications and one pig per EU. The growth performance study (Exp. III) involved 120 crossbred piglets: 60 entire males and 60 females (13.85 ± 1.49 kg). Treatments consisted of a gender combination and five levels of ASM (0, 3, 6, 9 and 12%), distributed in an RBD with six replications and four animals per EU. The physicochemical composition results indicated 86.12% of dry matter (DM), 8.03% of crude protein (CP) and 4,553 kcal kg-1 of gross energy (GE) as well as apparent digestibility coefficients of 39.04 and 28.21% for CP and GE, respectively. The levels of ASM that provided the maximum estimate for final body weight, daily body weight gain and average daily feed intake were 2.93% (p = 0.037), 3.05% (p = 0.040) and 4.27% (p = 0.043), respectively. ASM can be indicated as a dietary fibre source for starter piglet diets because it contains relevant nutritional and energy values, without affecting the nitrogen balance and blood urea concentration.

Acerola (Malpigia granatolistna, Malpighia emarginata DC./Malpighia glabra L.) – zastosowanie w żywieniu, profilaktyce zdrowia oraz w pozyskiwaniu substancji o znaczeniu przemysłowym

“…Wskazuje się również na wysoki współczynnik strawności pozornej (wynoszący 39,04%) dla białka zawartego w mączce z nasion aceroli. Wspomniane badania dowodzą, że mączka z nasion aceroli jest również cennym źródłem błonnika pokarmowego i pomimo wysokiej zawartości białka spożywanie jej nawet w dużych ilościach nie wpływa niekorzystnie na bilans azotowy i stężenie mocznika we krwi (Leal, 2021).…”
