1. The accretion of copper and zinc in maternal tissues, conception products and postnatal offspring of the rat was determined at different stages of pregnancy and lactation.2. Equations relating the weight of the bodies of the developing young and of the amounts of Cu and Zn in them to the time that has elapsed since conception showed that, early in pregnancy, the specific rates of accretion of Cu or Zn were greater than that of weight, but declined more rapidly as development continued. The instantaneous rates of accretion of both metals rose throughout pregnancy but only that of Cu continued to increase during lactation.3. The amount of Cu in the maternal body rose significantly during pregnancy and declined thereafter, but relatively small changes in its Zn content occurred.4. The results are discussed in relation to the relative demands for these metals during pregnancy and lactation.

An investigation of the effect of copper (Cu) and zinc (Zn) concentrations on their distribution in beef cattle tissues was conducted using feed trial with the following four nutrition treatments applied. At the end of the trial, samples of the muscular tissue, liver and kidneys of slaughtered cattle were taken from 10 head of cattle of the I group, 30 head of the II and III groups and 15 head of the IV group. The analyses were made by using the spectroscopic AAS method. Investigation results showed that all groups of cattle were given water with Cu and Zn contents below maximum permissible concentrations (MPC). The content of Cu and Zn in the tissues of the beef cattle in our experiment directly depended on their content in the concentrated feed. Copper is deposited in the liver the most, and Zn in the muscular tissue (excepting the II group of cattle). Correlation dependence of Cu and Zn content in the tissues from content in DM is complete (total), except in the case of Zn content in kidney, where is above mentioned correlation very strong (0.795).

ABSTRACT The offspring of bitches treated with thiouracil during pregnancy and lactation were studied with regard to certain aspects of iodine metabolism and also to the morphological effect on the thyroid gland, as compared with controls of the same age and weight. At the age of six months, when the dogs were virtually fully grown, the thyroid gland still exhibited the effects of the thiouracil treatment of the mothers as manifested by an increased uptake of 131I, enlargement, and histological changes of a hyperplastic type. The significance of these deviations from normal iodine metabolism and morphology is discussed with particular reference to the dangers of thiouracil medication during pregnancy.

SUMMARYFifty-two Large White gilts, arranged in thirteen groups of four litter sisters, were allocated at mating to one of four treatment groups. These treatments, arranged as a 2 × 2 factorial, allowed daily energy intakes in pregnancy of 8·3 Meal (H(e)) or 5·2 Meal (L(e)) and of average daily intake during lactation of 20 Meal (h(e)) or 13·8 Meal (m(e)). Daily intakes of protein, minerals and vitamins were similar for all treatments. There were no consistent differences in health or breeding regularity between the treatments.The H(e) sows had a net gain in pregnancy 22 kg greater than the L(e) sows. Feeding the higher level in lactation (h(e) resulted in a reduced sow weight loss during lactation of 20, 12 and 10 kg in the first, second and third parities respectively, as compared with the m(e) sows. There were no consistent effects on the numbers of pigs born apart from the first litter in which L(e) sows produced significantly larger litters at birth. The higher energy intakes in pregnancy and lactation led to very similar increases in the weights of the piglets, of the order of 0.1 kg at birth, 0.4 kg at 3 weeks of age, and 1.1 kg at 8 weeks of age. Sowsgiven the same overall energy intake throughout their reproductive life (H(e) m(e), L(e) h(e)) at the end of the third litter had similar live weights and had produced a similar total weight of weaned pigs. The practical implications of these results are discussed.
