“…When the protein level was decreased to 5%, resorptions (30%), stillbirths (17%) and reduced birth weights (to 5 g) were noted. That 5% protein was the critical protein level was earlier shown by Guilbert and Goss (1932) and also by Ambegoakar and Chandran (1959). Rats raised on a 2.5% protein or on a protein-free diet, showed a very high incidence of resorptions (70-100%) or early fetal deaths.…”

Data on the Growth of the Body and the Brain FollowingDietary Deprivation during Gestation andLactation. DEVELOPMENTAL PSYCHOBIOLOGY, 3(4): 28 1-301. The scanty data available on the effects of undernutrition during gestation and lactation upon neural development in man are reviewed briefly. This review is followed by a description of the various techniques that have been employed for the experimental undernutrition of laboratory animals. Then a detailed review is given of the effects of dietary deprivation during gestation, lactation, after weaning, and in adulthood upon the development of the nervous system and its different parts in a variety of mammalian species, with special emphasis on the rat. Finally, in a programmatic statement, the developmental phases during which undernutrition can be produced experimentally are related to critical stages or vulnerable periods of brain development. undernutrition brain growth

“…Stuart (1947) a montrk que des dkficiences en protkines provoquent des retards d'ossification. Guilbert et Goss (1932) avaient constatk, chez la rate, qu'avec des rkgimes renfermant moins de 5 yo de protides, il y avait frkquemment rksorption des fetus ou avortement. Henderson, Schweigert, Mozingo et Elvehjem (1948) ont vu chez le mCme animal que des protkines de diverses sources n'avaient pas la m&me valeur pour la reproduction et la lactation.…”

Summary The early development of an organism is a critical stage which many factors may influence unfavourably. Maternal nutritional deficiencies, especially vitamin deficiencies, can disturb the development and bring about the most diverse malformations, affecting the nervous system, eye, vascular system, kidneys, limbs, etc. The teratological effects of deficiencies in vitamin A, vitamin B2, pantothenic acid and folic acid are firmly established. Deficiencies not only produce malformations in the embryo. They may merely retard development, but they can also cause various lesions, and among others lesions which are analogous to those brought about in the adult by nutritional deficiencies. The gravity of the result of deficiencies varies greatly. It may be negligible or it may end in the death of the embryo or sterility of the mother. The effect is a function of the intensity of the deficiency, as shown by chemical estimations of the vitamin in question. A slight deficiency may produce a malformation. It may therefore occur readily, the more so as it may result from various causes, such as an insufficient exogenous or endogenous supply, a disequilibrium of the ration, imperfect utilization, etc. Deficiencies act on the embryo as on the adult, by a disturbance of metabolism, for it is known that many vitamins are essential constituents of enzymatic systems. The results of the deficiencies depend upon the tissues or cells with which these systems are specially concerned. At an early stage such metabolic disturbances may affect organizers and so cause anomalies in development, that is, deformities. Here, as elsewhere, genetical factors may intervene in restraining or facilitating the effect of a deficiency. It is probable that these phenomena, observed in several types of birds and mammals, are of general occurrence, to be found also in man and in domestic animals. From the practical point of view it follows that maternal nutrition should be closely supervised.

“…These workers compared the yield of milk from the amputated udders of eleven cows with the ante-mortem yields. The animals were divided into two groups, (1) in which the udders were allowed to become chilled after death, (2) in which the udders were maintained at approximately blood temperature until after the second post-mortem milking. The recovery of milk after amputation was 61-1 per cent, of the ante-mortem yield for group 1, and 75-3 per cent, for group 2.…”

“…That the protein level of the diet must be maintained at a definite level to ensure the recurrence and normality of the oestrous cycle is suggested by Guilbert and Goss (2). Macomber(3) also stresses the importance of this factor in the maintenance of lactation.…”
