    A significant portion of the world protein requirement is met by ruminants (sheep, goat, cattle). This is to increase the number of offspringraised by decreasing losses with the number of newborn per root as well as raising the intended yield of the animal breeder.Neonatal mortality in ruminants has remained stubbornly unchanging since long years, and represents a significant loss of farm income and affects animal welfare.However, deaths that occurred shortly before birth and within the first postpartum period are defined as prenatal period deaths. Deaths observed in this period are at the highest level. Post-natal period deaths are deaths inthe circuit from the weaning to the prenatal period. Environmental factors are more efficient in deaths in this period. In lambs, kids, calfmost deaths occur in the neonatal period. Causes include starvation, injuries, infectious conditions and difficultbirth,among others. Following birth, offspringareexposed to bacteria and pathogens that its immune system is unfamiliar with. Lamb and kid survival rate are the most important traits influencing income theherd. Therefore, a great deal of effort shouldbe put toward the care of pregnant and newbornsbefore, during, and after birth.Postnatal longevity is very important in the determination of the adaptation of newborns to the environmental conditions and the profitability of the enterprises.The newborns are essentialwithout immune protection as maternal antibodies are not transported across the placenta. An important strategy for newborn receives adequate colostrum during the first two to three hours of life.Colostrum, is rich with the antibodies thatprovide protection,from diseases in early life until the calf's own immune system becomes functional.Mortality is now considered the most crucial indicator of welfare level; it was an important indicator of management quality. The first 7 days of life can be to a new-born animal. The neonatal mortality seen in the first few months constitutes 84% of the total mortality rate.Priorities in newborns management; minimize stress at birth, maximize passive immunity, to meet the nutritional needs and maintain animal health as can be sorted. Because of improving the survival of neonatal lamb,kidsand calvesareessential for the economically and long-term genetic improvement.
