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.

实现了一项实验，以确定鞋带马铃薯残留物（SP），甜爆米花残留物（SPC）的营养成分和能量的化学成分和消化率，小麦甜饼干残留物（WSB）和小麦腌制残渣（WSS）用于仔猪。干物质（DM），粗蛋白（CP），乙醚提取物（EE），矿物质（MM），钙（Ca），测量磷（P）和钠（Na）和总能量（GE）。在连续两个12天的时间内（7个适应期和5个粪便收集期）在代谢板条箱中养殖的养猪用于评估饲料的消化率系数。SP，SPC，WSB和WSS的CP值相对较低7.2; 6.0;分别为6.8％和3.4％。 EE含量为39.64; 7.12; SP，SPC为12.40和22.28％; WSB和WSS分别。评估的所有副产物具有低的Ca和P值，并且任何人具有高于0.18％的Ca和P值并且SPC和WSS具有高Na水平（分别为0.9和1.36％）。通用电气是5.686; 3。995; 3.916; SP，SPC为4.953kcal kg-1; WSB和WSS分别与EE水平呈正线性相关（r2 \x3d 0.97; P 0.05）。需要进一步的研究来确定包含在猪日粮中的最佳副产品水平。然而，化学成分和营养物质和能量消化率的结果表明，鞋带土豆残留物，甜爆米花残留物，小麦甜饼干残留物和小麦盐渍残留物有可能用于仔猪的饮食。
