Table 1 Chicken feed composition; ingredients are listed as g/kg feed, and selenium analyzed in feed is given as mg/kg

From: N-3 fatty acid intake altered fat content and fatty acid distribution in chicken breast muscle, but did not influence mRNA expression of lipid-related enzymes

  1. The energy content of the feed was about 19 MJ/ kg, and the E% of ALA in the feed without LO was 0.7 E%, and it was 2.5 E% ALA in the feed with LO. It was 6 E% LA in the feed without LO and 4 E% LA in the feed with LO.
  2. *Fatty acid composition of the feed without LO: 35.6% 18:2n-6, 4.0% 18:3n-3 and n-6/n-3 = 8.7, and fatty acid composition of the feed with LO: 19.8% 18:2n-6, 14.3% 18:3n-3 and n-6/n-3 = 1.4. The percentage of 16:0, 18:0 and 18:1 were similar in the feed without LO and with LO, being about 18%, 9% and 27%, respectively.
  3. **Histidine 0.1%, choline choride 0.13%, mono-calcium phosphate 1.4%, ground limestone 1.3%, sodium chloride 0.25%, sodium bicarbonate 0.2%, vitamin A, E, D,K,B 0.18%, L-lysine 0.4%, DL-methionine 0.2%, L-threonine 0.2%.
