Disease and viruses as negative factor prohibiting the growth of broiler chicken embryo as research topic trend: a bibliometric review

Abstract

Background Broiler chickens have properties as meat-producing poultry and produce meat with soft fiber quality. Broiler’s embryo needs to be given attention, especially against disease. The purpose of the study was to observe the trend of the research topic and external factors which could affect the embryo’s growth of broiler. Methods This study used meta-data from Scopus. There were 162 samples started from 2006-to 2022. The data were analyzed using a bibliometric method with two software, Vosviewer, and Biblioshiy from R studio. Results It was found that the study of broiler chicken embryos had developed well, especially those related to genetics, disease, and also the immunity system. But the result showed that topics about the disease, viruses, and bacteria were more popular than topics about the gene. The result also showed that based on the importance and development of topics, the words such as “chicken”, “genes”, “development”, “effect”, growth”, and “control” had importance for the study and developed well in research. It means that genes influenced the growth of the embryo of a chicken. But still, even though a chicken gene was predetermined, the genetic engineering of chicken insemination to produce a superior breed with a fast-growing rate of the embryo could be used. Conclusions It could be stated that disease, especially research about the virus is one of the main determinants that could affect the growth of the embryo of broiler chicken.
