Catch-up Growth in Female Rats after Growth Retardation during the Suckling Period: Comparison with Males

Catch-up growth in the rat skull after retardation during the suckling period.

In rats whose growth was restricted by rearing in large litters the skull was less affected than the spine and the brain case less than the face. No sex difference was apparent during undernutrition but on subsequent rehabilitation females had caught up to controls in four out of five skull measurements within 4 weeks and by the end of the experiment the skulls of the neonatally undernourished ...

Growth Performance of Blackhead Pleven Lambs during the Suckling Period

The aim of the present study was to analyze the live weight, body length, and chest perimeter in Blackhead Pleven lambs at an early age with a view to their future use as prognostic indicators of growth performance. The study was conducted with 46 lambs. It found out that at birth and weaning the singletons had higher live weight and higher average daily weight gain in comparison with the twins (P

Nutritional Problems and Catch-Up Growth in Infants with Intrauterine Growth Retardation

In the past, it was common practice to relate low birthweight to prematurity. However, a number of environmental, maternal, placental, and fetal factors have been recognized as causing intrauterine growth retardation (IUGR) in babies who are small-for-gestational-age (SGA). In the more affluent societies, one-third of the low birthweight babies are SGA. Yet in communities where protein-energy m...

Growth of functional cranial components in rats with intrauterine growth retardation after treatment with growth hormone.

The goal of this study was to analyse the effect of growth hormone (GH) on catch-up growth of functional facial (splanchnocranial) and neurocranial components in rats with intrauterine growth retardation (IUGR). Wistar rats were divided into the following groups: control (C), sham-operated (SH), IUGR, and IUGR + GH. IUGR was surgically induced and GH was administered between 21 and 60 days of a...
