褐色菜鴨育成期黑木耳廢棄栽培介質飼糧對其產蛋性能之影響

本試驗旨在評估褐色菜鴨（Anas platyrhynchos domesticus）育成期餵飼黑木耳（Auricularia auricula-judae）廢棄栽培介質對其產蛋期性能之影響，以期能節省蛋鴨育成期飼料之成本。鴨隻於1－4週齡飼養於育雛室，餵飼育雛期飼糧；第5週齡起飼養於非開放式平飼鴨舍，並逢機分為4組，每組3重複欄，每重複欄13隻，共飼養156隻。第5－8週齡時，各處理組餵飼相同之生長期飼糧。第9至21週齡餵飼不同之育成期飼糧，分別為餵飼純碎玉米粒組（對照組）、以烘乾粉碎之黑木耳廢棄栽培介質（Waste cultivation medium, WCM）取代10%玉米組（WCM-10組）、取代20%玉米組（WCM-20）及取代30%玉米組（WCM-30組）。第22週齡起四組皆改餵飼相同含CP19%及ME 2,750 kcal/kg之產蛋期飼糧。試驗期間（9－42週齡）每週測定鴨隻體重、採食量及產蛋率；於24－36週齡每3週測定蛋重及蛋型係數；並於33及36週齡測定鴨蛋組成比例、蛋殼強度及蛋殼厚度。結果顯示，各組之採食量於育成期及產蛋期間並無明顯差異，21週齡時四組鴨隻體重在821－865 g之間。在產蛋率方面，四組22－42週齡之平均產蛋率依序分別為82、82、87及82%。在鴨蛋品質方面，各組間蛋黃、蛋白與蛋殼重量比、蛋殼厚度及蛋殼強度亦無顯著差異。綜合以上結果顯示，以黑木耳廢棄栽培介質作為蛋鴨育成期之飼糧原料，可取代玉米達20%，不影響產蛋率及鴨蛋品質，且可節省育成期飼糧成本17.55%，並有助於農業廢棄物循環利用。

The purpose of this experiment was to evaluate the effect of feeding waste cultivation medium of black fungus (Auricularia auricula-judae) on the laying performance in Brown Tsaiya ducks (Anas platyrhynchos domesticus) during development period, thereby to establish the reference on saving feed costs of laying ducks. Ducks are raised in brooding rooms at 1 - 4 weeks of age and fed starter feed; from the 5 weeks of age, the ducks are raised in the experimental duck house. The duck flock is divided into 4 testing groups, namely corn group (control), while the corn group is replaced by 10, 20 and 30% waste cultivation medium, respectively (WCM-10 , WCM-20 and WCM-30 group) . Each group consists of 3 repeating pens, with 13 ducks per repeating pen. A total of 156 ducks are raised. At 5 to 8 weeks of age, each group was fed CP and ME of 13.5% and 2,650 kcal/kg grower feed, respectively. From the 9 to 21 weeks of age, they were fed different treatments for development period. At 22 weeks of age, ducks were fed 19% of crude protein and 2,750 kcal/kg layer feed. During the test period (9 - 42 weeks of age), data on body weight, feed consumption and laying rate were collected every week, and egg weight and shape index were measured every 3 weeks from 24 to 36 weeks of age. Data on the composition ratio of duck eggs, eggshell strength and eggshell thickness were collected at 33 and 36 weeks of age. The results showed the follows: there was no significant difference in the feed consumption of groups between the limited feeding period and the laying period. The ducks weighed between 821 to 864 g at 21 weeks of age. In terms of laying rate, the average egg production rates for each group at 22 - 42 weeks of age were 82, 82, 87 and 82%, respectively. In terms of duck egg quality, there was no significant difference between the groups. The results showed that the waste cultivation medium of black fungus can be used as a feed ingredient in the laying duck's limited feeding period, which can be replaced by corn up 20% without affecting laying performance and egg quality and can save 17.55% of the feed cost during the development period.
