ABSTRACT The aim of this study was to investigate the effects of simultaneous supplementation of laying hens with dietary sources of n-3 polyunsaturated fatty acids (PUFA) and carotenoids on egg quality, fatty acids and carotenoid profile of the egg yolk and on feed and yolk lipid peroxidation. A 6-week experiment was carried out with 53-week old laying hens (96 Tetra SL) assigned to a control and three treatment groups supplemented with 5% flaxseeds and different levels of dried tomato waste (DTW, 2.5%, 5.0% and 10.0%). Hens from the groups supplemented with 5% and 7.5% DTW had a significantly lower average daily feed intake and laying percentage as compared to the control. Increased doses of dietary DTW enhanced yolk Roche colour score in direct correlation with the enrichment of egg yolk in carotenoids but decreased their transfer efficiency from feed to egg. After 4 weeks, egg yolk from hens fed with 5% flaxseeds and 7.5% DTW had increased lutein and zeaxanthin levels (by 29% and 24%, respectively) and the colour score was 3.5 fold higher compared to the control group. As a result of the dietary supplementation with flaxseed, the n-3 fatty acid content was 3.1–3.7-fold higher in egg yolk compared with the control and the n-6/n-3 ratio decreased from 18.3 (control) to 4.1–5.4 in supplemented diets. Dietary supplementation with 5% DTW effectively prevented lipid oxidation of eggs enriched with n-3 PUFA, but the increase in DTW content depressed the absorption and deposition of n-3 PUFA in egg yolk.

亚麻籽和干番茄废料一起用于蛋鸡饮食

摘要 本研究的目的是研究同时向蛋鸡添加 n-3 多不饱和脂肪酸 (PUFA) 和类胡萝卜素对蛋品质、蛋黄中的脂肪酸和类胡萝卜素成分以及对饲料和蛋黄的影响。脂质过氧化。对 53 周龄的蛋鸡 (96 Tetra SL) 进行了为期 6 周的实验,这些母鸡被分配到对照组和三个处理组,并补充了 5% 的亚麻籽和不同水平的干番茄废物(DTW,2.5%、5.0% 和 10.0 %)。与对照组相比,添加了 5% 和 7.5% DTW 的组母鸡的平均日采食量和产蛋率显着降低。日粮 DTW 剂量的增加提高了蛋黄 Roche 颜色评分,这与蛋黄中类胡萝卜素的富集直接相关,但降低了它们从饲料到鸡蛋的转移效率。4 周后,用 5% 亚麻籽和 7.5% DTW 喂养的母鸡的蛋黄叶黄素和玉米黄质水平增加(分别增加 29% 和 24%),与对照组相比,颜色评分高出 3.5 倍。由于膳食补充了亚麻籽,蛋黄中的 n-3 脂肪酸含量比对照高 3.1-3.7 倍,n-6/n-3 比率从 18.3(对照)降至 4.1- 5.4 在补充饮食中。日粮中添加 5% DTW 可有效防止富含 n-3 PUFA 的鸡蛋的脂质氧化,但 DTW 含量的增加抑制了蛋黄中 n-3 PUFA 的吸收和沉积。4 周后,用 5% 亚麻籽和 7.5% DTW 喂养的母鸡的蛋黄叶黄素和玉米黄质水平增加(分别增加 29% 和 24%),颜色评分比对照组高 3.5 倍。由于膳食补充了亚麻籽,蛋黄中的 n-3 脂肪酸含量比对照高 3.1-3.7 倍,n-6/n-3 比率从 18.3(对照)降至 4.1- 5.4 在补充饮食中。日粮中添加 5% DTW 可有效防止富含 n-3 PUFA 的鸡蛋的脂质氧化,但 DTW 含量的增加抑制了蛋黄中 n-3 PUFA 的吸收和沉积。4 周后,用 5% 亚麻籽和 7.5% DTW 喂养的母鸡的蛋黄叶黄素和玉米黄质水平增加(分别增加 29% 和 24%),与对照组相比,颜色评分高出 3.5 倍。由于膳食补充了亚麻籽,蛋黄中的 n-3 脂肪酸含量比对照高 3.1-3.7 倍,n-6/n-3 比率从 18.3(对照)降至 4.1- 5.4 在补充饮食中。日粮中添加 5% DTW 可有效防止富含 n-3 PUFA 的鸡蛋的脂质氧化,但 DTW 含量的增加抑制了蛋黄中 n-3 PUFA 的吸收和沉积。比对照组高 5 倍。由于膳食补充了亚麻籽,蛋黄中的 n-3 脂肪酸含量比对照高 3.1-3.7 倍,n-6/n-3 比率从 18.3(对照)降至 4.1- 5.4 在补充饮食中。日粮中添加 5% DTW 可有效防止富含 n-3 PUFA 的鸡蛋的脂质氧化,但 DTW 含量的增加抑制了蛋黄中 n-3 PUFA 的吸收和沉积。比对照组高 5 倍。由于膳食补充了亚麻籽,蛋黄中的 n-3 脂肪酸含量比对照高 3.1-3.7 倍,n-6/n-3 比率从 18.3(对照)降至 4.1- 5.4 在补充饮食中。日粮中添加 5% DTW 可有效防止富含 n-3 PUFA 的鸡蛋的脂质氧化,但 DTW 含量的增加抑制了蛋黄中 n-3 PUFA 的吸收和沉积。
