We know that feeding and using amino acids in poultry diets affect growth and development and possible evaluation of egg traits. Therefore, in this article, we will discuss the effects of amino acids in broiler pullet breeding and egg weight characteristics from 26 to 34 weeks of age. Stay tuned.<\/p>\n
\n
Methodology:<\/p>\n
In this study, the effect of four amino acids on egg characteristics was investigated from weeks 5 to 24. Up to 4 weeks of age, all pullets were fed a starter diet. After 29 days, they were fed Mash grower, which contained 4 types of amino acids. (0.4 \u2013 0.54 \u2013 0.6 and 66% lysine with protein balance and 2700 calories \/ kg methionine).<\/p>\n

Since egg production reached 5%, all chickens were fed the same diet and we increased feed according to egg production. Egg production started on day 165 and increased by 5% on day 167. Egg weight in 30 hens was assessed after reaching 50% of egg production at weeks 26, 28, 30 and 32. Egg color, firmness and thickness of 6 hens were examined at week 30. Percentage changes in egg components, albumin, yolk and eggshell were calculated and measured in Haugh units.<\/p>\n
\n
Results:<\/p>\n
The results showed that amino acid levels (p < 0.05) affected egg weight up to week 28. Eggs from hens consuming high levels of amino acids were about 2 g heavier than eggs from hens consuming lower levels of amino acids. However, this effect was not seen at weeks 30, 32 and 34. No effect (p < 0.05) was observed on eggshell color, thickness and yolk color. Eggshell strength and elasticity (p < 0.05) were lower in hens fed a high amino acid diet (37.9N) than in eggs fed a lower amino acid diet (42.5N). In general, amino acids affected shell strength and weight.<\/p>\n
