摘要

種雞場孵化室及種蛋受微生物的污染，嚴重影響小雞的品質及其生長性能，當小雞孵出時污染的微生物會附在絨毛上，因此測定絨毛的微生物是評估孵化室衛生情形方便的方法。由2002年至2007年全國有18-23個種雞場孵化室送絨毛至台大禽病室，進行總菌數、沙門氏菌及黴菌污染的情形，以評估孵化室的衛生狀況。絨毛總菌數以l0g值表示並分級，大多孵化室絨毛總菌數皆達1至2級。以3季以上污染為標準，有3個孵化室受沙門氏菌的污染，有2個受沙門氏菌污染的孵化室關閉；5個孵化室受黴菌的污染。依此絨毛微生物監測的結果，種雞場孵化室經清潔及消毒，得以隨時監控保持其衛生狀況，保證小雞的品質。

Microorganism contamination in hatchery and eggs has a serious impact on the viability and quality of chicks as well as on the overall growth performance of chickens. Microbiological agents are present in the fluff when the chicks hatch. Detecting microorganisms in fluff is a convenient method for evaluating the hygienic status in a hatchery. Fluff samples from 18-23 hatcheries were tested for the total bacterial count, the presence of Salmonella spp., and fungus to evaluate the hygienic status of hatcheries in Taiwan from 2002 to 2007. The total bacterial score (BS) from the fluff samples was calculated and expressed as a log scale. Most hatcheries had a BS that ranged from scale 1 to 2. Salmonella contamination more than three quarters in a year was found in 3 hatcheries. Two of them closed after then. Five hatcheries were contaminated with fungus for more than three quarters in a year. According to the data obtained from the fluff test, hatcheries keep their hygienic status by cleaning and disinfecting the hatchery and supply chicks in good quality.
