Recent approaches in pregnancy nutrition of slaughter animals

33921

The success of pregnancy in slaughter animals depends on the relationship between growth anddevelopment of fetus (es) and the level of nutrient intake of the maternal and fetus in the embryonic andfetal period. This situation is very important in determining the efficiency throughout the life of offspring (postnatal body composition, growth rate, efficiency parameters, meat quality, etc.). Increasing of thedaily live weight gains and marble rate in meat in the fattening and consequently to obtain higher and quality meat in terms of producers and consumers depend on manipulation of factors affecting foetalmuscle (myogenesis) and fat (adipogenesis) formation during prenatal period. In this review, it wasfocused on various signal pathways and their receptors managed the myogenesis and adipogenesis process prenatal and thus influenced the meat yield and quality (marble) by affecting formation of muscle(Wnt, β- catenin, Shh, Pax7, etc.) and fat (PPARγ, nuclear factor-KB, tumor necrosis factor-α, etc.) in fetus .The inhibition or activation of these signal paths with the feeding level and some feed additivesduring pregnancy were also evaluated. As a result, there are need further investigations for betterunderstanding of mechanisms which are activated signal pathways and receptors managed the fetal muscle (myogenesis) and fat (adipogenesis) formation during prenatal period and the effects of feedingon this mechanism.
