Аннотация
В этом эксперименте с помощью однофакторного теста было выбрано 180 кур Леггорн в возрасте 231 дня с одинаковой массой тела, которые были выбранный случайно и разделены на 4 группы A, B, C и D. В каждой группе было 5 повторений и 9 кур. Группа А была контрольной группой, В, С и D была получавшей базальную диету, и к основному рациону добавлялись 2 мг/кг, 4 мг/кг и 6 мг/кг апоэстера. Тест на кормление проводился в течение 35 дней. Влияние различных уровней апоэстера на продуктивность и качество яиц, кур исследовали путем определения продуктивности и качестве яиц.
Результаты показали, что добавление в рацион от 2 до 6 мг/кг апоэстера не влияло на среднесуточное потребление корма, массу яиц, соотношение яичного материала и продуктивность яиц, но оказывало значительное влияние на качество яиц, индекс формы, масса яичного желтка и цвет яичного желтка.

Institute of Telecommunications and Informatics of Turkmenistan EFFECTS OF APO-ESTER ON PERFORMANCE OF LAYING HENS AND EGG QUALITY
Abstract
In this experiment, a single factor test was used to select 180 Leghorn laying hens aged 231d with similar body weight, which were randomly divided into 4 groups of A, B, C and D. Each group had 5 repetitions and 9 hens. Group A was the control group, fed basal diet, B, C and D as the treatment group, and 2mg/kg, 4mg/kg and 6mg/kg were added to the basal diet respectively. The feeding test was carried out for 35 days. The effects of different levels of apo-ester on the production performance and egg quality of laying hens were investigated through the determination of production performance, egg quality.
The results showed that adding 2mg/kg to 6mg/kg apo-ester in diet did not affect the average daily feed intake, egg weight, egg material ratio and egg production rate, but had significant influence on the egg quality, egg shape index, egg yolk weight and egg yolk color.

Beta-apo-8'-carotene ethyl ester(Apo-ester) as a kind of pigment allowed to be applied, the current research is to add it and other pigments together with the egg and chicken feed, for individual as an additive. Apo carotene acetyleste (Apo-ester) is widely found in natural plants, and current research shows that autin is a colorant that has been used in production and has been shown to be used in garicin yellow processing, and thus the resulting product coloring effect of better use of the value significantly improved, but also because poultry has high bio availability, which is cheap and easy to obtain. In WHO, SCF, MAFF, MOA, etc. the Apo-ester got extensive, but in practical application, because of its sensitivity to humidity, light, O2, temperature and other natural conditions. This as a result of the destruction of the Apo-ester in the feed add process, which puts strict requirements on the production process, also it has promoted the further development of Apo-ester.
Adding 20mg/kg of carotene, 5mg/kg carry red, 30mg/kg carry yellow, 0.5% pine paste powder to broiler feed can make the chicken taser color of more than 4% or more, compared to the control group only 3 5% ; From 7 days before the broiler is on the market, add 100mg of the commodity Luctone (consisting of 1 lukangdin red, 2 lucid yellow and micro dispersants) to drink 100mg per day in the drinking water of 30 to 40 degrees C, and drink continuously for 5 days, The skin of the broiler is presented in a satisfactory golden color, and there have also been reports that pine needle powder and corn protein powder and carry red and carry yellow, the skin, toes, the color of the broiler has been significantly improved, and to add skin Lute in 300mg/kg or carry yellow 40mg/kg works best with garissin red 10mg/kg. Material and method
Basic feed: produced by Hubei Nong Teng Feed Co., Ltd. The nutritional needs of egg chicken in accordance with the NRC (1994) egg chicken standard.
Apo-ester powder: provided by a Wuhan company, the content of Apo-ester is 5%. Experimental animals: 30-40 weeks old Leghorn. The feed-based of the test group was mixed with Apo-ester powder.
Total 180 Leghorn laying hens selected (231d) with good health, similar weight and randomly divided into A, B, C, D 4 groups, each group 5 repeat, each repeat 9 chickens. Group A is a control group, feeding the base diet, B, C, D as the treatment group, added in the base diet of Apo-ester powder 40 mg/kg, 80 mg/kg, 120 mg/kg /kg (equivalent to adding 2 mg/kg, 4 mg/kg, 6 mg/kg) in the diet respectively. The feeding test time is 35 days.
Based on a single-factor, completely random approach to the group design, healthy chickens of similar weight of 231 days were randomly divided into 4 groups (2, 4, 6 mg/kg apo-ester added to the control group and diet, respectively) for each group of 5 repetitions, each repeating 9 chickens. Results
The addition of 2 mg/kg to 6 mg/kg apo ester in the diet had no significant effect on the average daily harvest of egg chickens, average egg weight, total egg weight, egg ratio and egg yield.

Effect of different amounts of apo-ester on the health of egg and chicken
The effects of Apo-ester on egg-chicken serum hydrogen peroxide enzyme (CAT), superoxide gibbeliase (SOD), glutathione peroxidase (GSH-PX) and total antioxidant capacity (T-AOC).
Adding apo-ester to the diet increases the activity of serum GSH-PX, with the most significant effect on adding levels from 2 mg/kg to 4 mg/kg. But there is no significant effect on SOD, CAT, T-AOC activity.

Summary
Laying hens daily grain added 2mg/kg to 6 mg/kg apo-ester and daily harvested, average egg weight, egg ratio, egg quality (egg index, egg weight, hatch unit, eggshell thickness, protein height), egg yellow and egg cholesterol content are not significantly affected. References
