They may be summarised: Thermoregulatory behaviour is developed early in poultry embryos. Temperature of allantoic fluid (Taf) represents the internal body temperature in the last third of incubation because Taf and Tc are much the same at normal (37.5C) and low incubation temperatures (34.5C) after internal pipping. Fowl embryos show endothermic reactions from day14 and Muscovy duck embryos from day 22. In precocial avian embryos, body core temperature increases in accordance with heat production. In contrast to heat production the efficiency of heat loss is high in precocial avian embryos. Development of physiologicalcontrol systems starts withnon-co-ordinatedandproximate (immediate) non-adaptive reactions. In summary, endothermic reactions occur very early during embryonic development but their efficiency is limited. Due to the van’t Hoff rule, low temperatures decrease the net heat production but the trajectories of endothermy are stimulated and related epigenetic adaptation mechanisms are activated. Using behavioural mechanisms the embryo is protected against super-cooling during the natural incubation process. The heat loss mechanisms are most efficient against heat stress, which may occur for only very short time during incubation, protect the embryo against disturbances caused by hyperthermia.","PeriodicalId":118534,"journal":{"name":"Avian and Poultry Biology Reviews","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128623612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reproduction is controlled at the central nervous level by gonadotrophin releasing hormone-I (GnRH-I) and prolactin. 3. The activity of GnRH-I neurones can be manipulated photoperiodically, through understanding of the physiology of photorefractoriness, to prevent premature onset, or to enhance persistency of reproductive function. 4. Active immunisation against prolactin releasing hormone, vasoactive intestinal peptide, delays the development of photorefractoriness and enhances persistency of reproductive function. 5. The creation of molecular maps of the chicken genome makes it possible to identify quantitative trait loci for repro- ductive traits, which will be used to identify DNA sequences for marker assisted selection. Polymorphisms in alleles of physiological candidate genes for reproductive efficiency might also be useful for marker assisted selection. 6. New understanding of the developmental biology of the chicken opens up the prospect of developing methods to control sex ratios, and to make transgenic birds. Transgenic technology will be used to introduce genes for disease resis- tance, and to make proteins for biomedical applications. 7. Nuclear transfer technology might be applied to save endangered species from extinction.","PeriodicalId":118534,"journal":{"name":"Avian and Poultry Biology Reviews","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130743112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
