这种鸡蛋，是什么原因形成的？

应该是卵巢疾病引起的。

Mottled yolks have been attributed to：
1.Poor handling and storage
2.Thin shells
3.Gossypol in cottonseed meal
4.Treatment for worms
5.Certain antioxidants
6.Raw soybean meal
Discoloration of yolks has been attributed to:
1.Gossypol in cottonseed meal
2.The weed shepherd’s purse
3.Cyclopropene fatty acids in cottonseed and certain weeds, e.g. marshmallow
4.DPPD (diphenyl-para-phenylenediamine)
5.Worms or disease
6.Balance of yellow to red pigments

如果鸡群的采食量和产蛋率正常，可能和原料有关。
请问这种情况发生的比例和持续时间？配方是否调整？是否使用非常规的原料？

群体性应考虑饲料问题，个别性才是疾病问题。

疾病或者原料质量有问题，就不会一个月了还产蛋正常，所以肯定是其他原因

Internal Defects
内部缺陷
Mottled yolks and discoloured yolks  
斑驳的黄和变色的蛋黄
Description  
描述
The colour of the yolk may be uneven or patchy, as shown, or vary from the desired colour range (deep-yellow to orange-yellow).
颜色的蛋黄可能不均匀或片状，如图所示，或不同所需的颜色范围（deep-yellow至橙黄色）。
Incidence
发病率
Some degree of mottling occurs in more than 50% of all eggs. The severity of mottling increases as eggs become stale. Discoloured yolks are rare.
一定程度的斑块发生在50%以上的所有鸡蛋。严重的色斑增加鸡蛋成为陈旧。蛋黄是罕见的变色。
Cause Control
因为控制
Mottled yolks have been attributed to:
斑驳的蛋黄已归因于：
Poor handling and storage
可怜的处理和储存
Minimise storage time on the farm by:  • increasing the number of pick-ups per week for grading or delivery to retail outlets.  • collecting and packing eggs laid on pick-up days so that they are consigned on that day.  • grading eggs while they are fresh when packing on the farm. Do not allow the temperature in the layer shed to become too high. Keep the coolroom temperature below 20 °C, e.g. at 12 to 15 °C (guidelines/requirements may vary in different countries) and the humidity at 70 to 80%.  Examine egg handling procedures and equipment and modify to minimise rough handling. Oil eggs soon after collection. Use only an oil approved for this purpose by the relevant authorities.
尽量减少储存时间对农场：•增加一些传感器每星期分级或交付给零售店。•收集和包装卵回升，于是他们委托当日。•分级鸡蛋，趁鲜包装时在农场。不要让温度在层棚变得太高。保持coolroom温度低于20摄氏°，例如在12至15摄氏°（准则要求可能因国家而异），湿度在70至80%。检查蛋处理程序和设备和修改，减少粗糙处理。不久后收集油蛋。只使用一个油批准用于这一目的的有关当局。
Thin shells
薄壳
Make sure that feed contains the correct amounts and proportions of nutrients, particularly calcium.
确保饲料包含正确的数量和比例的营养，尤其是钙。
Gossypol in cottonseed meal
棉子饼粕中棉酚
Limit cottonseed meal with high gossypol content to 5% of the layer diet (recent work indicates that up to 10% of some solvent-extracted cottonseed meal products can be safely used as they have low levels of gossypol due to newer varieties and improved processing). If the diet contains high gossypol cottonseed meal, add iron at the rate of 0.05% by weight of the diet. This can be achieved by adding ferrous sulphate powder at the rate of 0.25% by weight of the diet.
限制高棉酚的棉籽粕含量的5%层饮食（最近的工作表明，多达10%的一些脱酚棉籽粕可以安全地用来作为他们有低层次的棉酚由于新品种改良和处理）。如果饮食中含有高棉酚的棉籽粕，添加铁的速度在0.05%的重量的饮食。这可以通过添加硫酸亚铁粉率在0.25%的重量的饮食。
Treatment for worms
治疗蠕虫
Do not use combinations of the worming drugs piperazine, phenothiazine and dibutyltin dilaurate immediately before or during lay. However, the use of any one of these drugs at the recommended and approved dose rate is not detrimental.
不要使用组合的驱虫药哌嗪，吩噻嗪和二月桂酸二丁基锡，立即之前或期间躺。然而，使用任何一种这些药物的建议和批准剂量率不是有害的。
Certain antioxidants Do not feed gallic acid or tannic acid to laying hens.
某些抗氧化剂不喂没食子酸和单宁酸对蛋鸡。
Raw soybean meal Use only heat-treated soybean products in layer diets.
大豆粉只使用热处理大豆产品蛋鸡日粮。
Discoloration of yolks has been attributed to:
变色蛋黄已被归因于：
Gossypol in cottonseed meal
棉子饼粕中棉酚
Prevent bluish-green yolks by limiting cottonseed meal with high gossypol content to 5% of the layer diet. New varieties and improved processing of CSM have been developed that have low levels of gossypol. If the diet contains cottonseed meal with high gossypol levels, add iron at the rate of 0.05% by weight of the diet. This can be achieved by adding ferrous sulphate powder at die rate of 0.25% by weight of the diet.
蓝黄，防止通过限制高棉酚的棉籽粕含量的5%层饮食。新品种改良和处理的病已经制定，有低层次的棉酚。如果饮食中含有高棉酚的棉籽粕水平，增加铁的速度在0.05%的重量的饮食。这可以通过添加硫酸亚铁粉死率0.25%的重量的饮食。
The weed shepherd’s purse Prevent green yolks by excluding this plant from the diet.
杂草荠菜防止绿蛋黄排除这种植物的饮食。
Cyclopropene fatty acids in cottonseed and certain weeds, e.g. marshmallow
环丙烯脂肪酸在棉籽和某些杂草，如棉花糖
These substances may cause the yolk to become a salmon colour after storage. Exclude weeds from the layer diet.
这些物质可使蛋黄成为鲑鱼色后存储。从饮食中排除草层。
DPPD (diphenyl-para-phenylenediamine)
dppd（diphenyl-para-phenylenediamine）
The antioxidant DPPD (diphenyl-paraphenylenediamine) (where approved for use) can cause excessive amounts of pigments from the feed to be deposited into the yolk.
抗氧化dppd（diphenyl-paraphenylenediamine）（凡批准使用）可能会导致过量的颜料从饲料存入蛋黄。
Worms or disease
蠕虫病
Disease or infestation with capillaria worms (cropworms) can produce ‘blond’ or ‘platinum’ yolks. Follow effective vaccination programmes against disease, observe hygiene measures and control worms.
疾病或感染毛细蠕虫（cropworms）可以产生“金发”或“白金”蛋黄。按照有效的疫苗接种方案，遵守卫生措施和控制蠕虫。
Balance of yellow to red pigments
平衡黄色至红色的颜料
A low yellow:red carotenoid ratio in the feed, for example 1.25:1, will produce apricot-coloured yolks. Maintain a yellow:red ratio of approximately 3:1, particularly when diets are low in natural pigments.
低黄红色的类胡萝卜素在饲料中的比例，例如1.25 : 1，将产生是杏黄色的蛋黄。保持一个黄色：红色的比例约为3 : 1，特别是当饮食低，天然色素。
