Lactobionic acid is an innovative product obtained in the fermentation process of cheese or curd whey, and it has several beneficial properties. Therefore, it may have potential application in animal feeding. Currently, lactobionic acid is not widely used yet in feeding farm animals. Therefore, the aim of our study was to evaluate the effect of lactobionic acid (LBA) on pig growth performance and pork quality. Two groups of pigs (control and trial, 26 piglets each) were completed. The control group received compound feed, whereas the trial group's feed was supplemented with LBA (0.17 kg per 100 kg of feed). Carcass weight and meat pH were determined. The subcutaneous fat layer S (mm) was measured. Lean meat content was determined using the SEUROP classification. Amino acids and fatty acids in pork were evaluated. The addition of LBA to pig feed significantly increased the live weight gain and slaughter yield of pigs, but the samples had a slightly thicker backfat layer. Results obtained showed higher concentration of amino acids in the trial group but slightly lower pork fat quality in the same group. Lactobionic acid has the potential for applications in pig feeding.
乳糖酸是在奶酪或凝乳清发酵过程中获得的一种创新产品，它具有多种有益特性。因此，它可能在动物饲养中有潜在应用。目前，乳糖酸在养殖动物饲料中的应用还不广泛。因此，我们研究的目的是评估乳糖酸（LBA）对猪生长性能和猪肉品质的影响。完成了两组猪的实验（对照组和试验组，每组26头仔猪）。对照组饲喂复合饲料，而试验组的饲料添加了LBA（每100千克饲料添加0.17千克）。测定了胴体重和肉的pH值。测量了皮下脂肪层厚度S（毫米）。使用欧洲胴体分级系统测定瘦肉含量。评估了猪肉中的氨基酸和脂肪酸。在猪饲料中添加LBA显著提高了猪的体重增加和屠宰率，但样本的背膘层略厚。结果显示，试验组氨基酸浓度较高，但同一组猪肉脂肪品质略低。乳糖酸在猪饲养中具有应用潜力。
