The aim of this research was to determine the effects of coating broiler hatching eggs with chitosan on egg quality, embryonic growth, hatching results and chick quality. Eggs obtained from old broiler breeder, aged 59 weeks, were used. Eggs were divided into two groups (coated with chitosan and uncoated) groups. Each group was divided into three groups according to the storage period. Eggs were stored for periods of 1, 4 and 7 days at 15°C and 80% humidity. Then, they were incubated. Storage period of eggs up to 7 days did not affect the egg quality, egg weight loss, embryo growth, chick properties and hatchability of fertile eggs. However, embryo development, relative residual yolk sac weight and relative chick weight were affected by coating eggs with chitosan. Interaction was not found between storage lengths and coating of eggs with chitosan for all examined parameters. The results of the present study suggested that hatching eggs obtained from old broiler breeder flocks were immersed into chitosan solution once and quickly have negative effect on the embryo weight, yolk sac absorption and relative chick weight. It has been observed that covering the hatching eggs with chitosan is not suitable in this respect even if immersion takes place once and in a short time.

含壳聚糖的老肉种鸡包膜孵化蛋对胚胎生长、孵化结果和雏鸡品质的影响

本研究的目的是确定用壳聚糖包裹肉鸡孵化蛋对蛋质量、胚胎生长、孵化结果和雏鸡质量的影响。使用从 59 周龄的老肉种鸡获得的鸡蛋。鸡蛋分为两组(涂有壳聚糖和未涂漆)。每组按贮藏时间分为三组。鸡蛋在 15°C 和 80% 湿度下储存 1、4 和 7 天。然后,他们被孵化。鸡蛋的储存期长达 7 天不会影响鸡蛋质量、鸡蛋重量损失、胚胎生长、雏鸡特性和受精鸡蛋的孵化率。然而,胚胎发育、相对残余卵黄囊重量和相对雏鸡重量受壳聚糖涂层鸡蛋的影响。对于所有检查参数,未发现储存长度和用壳聚糖包裹鸡蛋之间的相互作用。本研究的结果表明,从老肉鸡种鸡群中获得的孵化蛋在壳聚糖溶液中浸泡一次,很快就会对胚胎重量、卵黄囊吸收和相对雏鸡重量产生负面影响。已经观察到,在这方面用壳聚糖覆盖孵化蛋是不合适的,即使浸没发生一次且在短时间内。
