Project description:To investigate genes involved in abdominal fat deposition and fat metabolism of broilers, we used highthroughput sequencing to detect the differentially expressed genes in livers and abdominal fats of broilers which were fed with a normal diet and a high-fat diet, respectively. The broilers began to fed with a normal or a high-fat diet in 1-week-old. After 7 weeks, the broilers were be executed and the livers and abdominal fats were used to extracted total RNAs. Finally, the total RNAs were be sequenced used BGISEQ-500 platform.
Project description:To investigate genes involved in abdominal fat deposition and fat metabolism of broilers with dw gene, we used highthroughput sequencing to detect the differentially expressed genes in livers and abdominal fats of dwarf broilers which were fed with a normal diet and a high-fat diet, respectively. The broilers began to fed with a normal or a high-fat diet in 1-week-old. After 7 weeks, the broilers were be executed and the livers and abdominal fats were used to extracted total RNAs.

Project description:Adding lysolecithin to feed has reportedly improved the performance of broiler chickens. Lysolecithin is generated by phospholipase catalyzed hydrolysis of lecithin. The enzymatic reaction converts phospholipids into lysophospholipids, with lysophosphatidylcholine (LPC) the primary product. Here we compared supplementation with a commercial lysolecithin (Lysoforte(R) Kemin Industries, Inc., Des Moines, IA) with comparable levels of purified LPC for effects on broilers. Despite no differences in weight gain during the starter period, we discovered a significant increase in average villus length in the jejunum with lysolecithin, but not with LPC. High-throughput gene expression microarray analyses revealed many more genes were regulated in the epithelium of jejunum by lysolecithin compared to LPC. The most upregulated genes and pathways were for collagen, extracellular matrix and integrins. Staining sections of jejunum with Sirius Red confirmed the increased deposition of collagen fibrils in villi of broilers fed lysolecithin but not LPC. Thus, lysolecithin elicits gene expression in the intestinal epithelium leading to enhanced collagen deposition and villus length. LPC alone as a supplement does not mimic these responses. Feed supplementation with lysolecithin triggers changes in the intestinal epithelium with the potential to improve overall gut health and performance.
