LACTATION, WEANING PERIOD, FOOD QUALITY, AND DIGESTIVE TRACT DIFFERENTIATIONS IN EUTHERIA

Effect of milk deprivation during the lactation period on performance and digestive enzyme activities of the piglets following weaning.

Post-weaning performance of piglets from systems where lactation is disrupted (e.g. from multisuckling systems) is superior to conventionally reared piglets. The objective of this study was to establish whether restricted growth prior to weaning caused by disruption of suckling was an important factor in post-weaning performance and also whether there were related changes in gastro-intestinal d...

Digestive capacity of the rabbit during the post-weaning period, according to the milk/solid feed intake pattern before weaning.

The milk/solid feed intake pattern and digestive capacity were compared in two groups of young rabbits reared between 16 and 32 days in litters of four (L4 group, n = 18 litters) or ten pups (L10, n = 20) in order to modulate milk availability. Compared to the L4 group, rabbits in the L10 group presented a lower milk intake (22.3 versus 28.8 g x day(-1)) and a higher solid feed intake (12.9 ver...

Insulin receptors: the binding capacity and localization in the digestive tract during the rabbits neonatal period.

The aim of this study was to localize and measure the receptor-binding capacity for insulin in the stomach, duodenum, ileum, jejunum, caecum, colon and in isolated hepatocytes in 48 rabbits aged 1-7, 14 and 21 days. Two methods were employed: radioimmunoassay (RIA) and receptor-binding assay (RBA). Isolated rabbit hepatocytes were used to estimate the maximal binding (Bo). Insulin (INS) concent...

This small book is an attempt to review present knowledge on the morphology, immunology, and pathogenicity of the pleuropneumonia-like organisms (PPLO). The author is a recognized authority on these organisms and the material is presented from her point of view, although she readily admits that there are some who may be in disagreement with her conclusions. Four of the eleven chapters are devot...
