【 摘 要 】

One experiment was realized to determine the chemical composition and digestibility of nutrients and energy of shoestring potatoes residues (SP), sweet popcorn residues (SPC), wheat sweet biscuit residues (WSB) and wheat salted sticks residues (WSS) for piglets. The dry matter (DM), crude protein (CP), ether extract (EE), mineral matter (MM), calcium (Ca), phosphorus (P) and sodium (Na) and gross energy (GE) were measured. Eighteen castrated pigs penned in metabolic crates during two consecutive periods of 12 days (seven to adaptation and five to feces collection) were used to evaluate the digestibility´s coefficients of feedstuffs. The SP, SPC, WSB, and WSS had relatively low CP values 7.2; 6.0; 6.8 and 3.4%, respectively. The EE contents were 39.64; 7.12; 12.40 and 22.28% for SP, SPC; WSB and WSS, respectively. All the co-products evaluated had low values of Ca and P and anyone had a Ca and P value higher than 0.18% and the SPC and WSS had high Na levels (0.9 and 1.36%, respectively). The GE were 5.686; 3.995; 3.916; 4.953kcal kg-1 for SP, SPC; WSB and WSS, respectively and showed positive linear correlation (r2=0.97; P<0.05) with EE levels. Additional studies are necessary to establish the optimal levels of co-products to include in pigs diets. However, the results of chemical composition and digestibility of nutrients and energy indicate that shoestring potatoes residues, sweet popcorn residues, wheat sweet biscuit residues and wheat salted sticks residues have potential to be used in piglet's diets.
