Serum lipidomics analysis reveals yolk sac absorption differences in newly hatched chicks.

ABSTRACT: The yolk sac provides nutrients to a newly hatched chick with maternal nutrient substances including large amounts of lipids. Higher resorption of the yolk sac is generally considered positive for chick development. However, it is hard to determine yolk sac absorption differences among living chicks with similar body weight for assessing chick quality. In this study, we explored the serum lipidome changes using a lipidomics strategy to elucidate the underlying mechanisms of yolk sac absorption difference in day-old chicks and determine some effective indicators for chick quality evaluation. A total of 588 hatching eggs were collected from a breeder flock and classified into 7 weight categories (56-70 g, with 2 grams in each category). After hatching, the chicks were grouped into 12 groups
