- Abstract
The experiment was to investigate the self-made feed, egg production and egg quality in the farms of Mei-si tribal village, Ren'ai Township, Nantou County in 2020 for the advisory the layer farms. Feed composition, heavy metals, egg production performance and egg quality were analyzed and recorded. The results indicated that moisture, crude fat, crude protein, crude fiber, calcium and phosphorus of feeds were 21.0%, 9.2%, 21.9%, 5.5%,2.2%, and 0.4%, respectively. Pb, Hg, Cd, As, Cu and Zn of heavy metals were 0.4 ppm, ND, 0.1 ppm, 0.4 ppm, 9.8 ppm and 44.0 ppm, respectively. In egg production performance, because of 2 year old Lohmann layers and nature farming, although 100% livability, egg production rate was only 6.1 ± 2.6% and average egg weight and feed conversion ratio was 60 ± 9 g and 32.9 ± 24.6, respectively. In egg quality, average egg weight, Haugh unit, albumin height, egg shape coefficient, egg shell thickness, egg shell strength and egg yolk color were 61.9 ± 4.3g, 45.3 ± 8.3, 3.104 ± 0.522 mm, 0.73 ± 0.02, 0.359 ± 0.024 mm, 3.666 ± 1.188 kg/cm² and 5.3 ±1.6, respectively.
