Adaptation to pregnancy involves major maternal anatomical, physiological and metabolic modifications to support the mother's metabolic needs and those of the growing foetus. Invasion of embryonic territories and implantation in humans and other mammals is the result of an active biochemical process. The invasive faculty of cytotrophoblastic cells depends on their capacity to secrete proteolytic enzymes such as matrix metalloproteinases (MMPs). Many studies have addressed the variations in MMPs in placental tissues, but few have reported on their measurements in plasma. Furthermore, the Pregnancy-Associated Glycoproteins (PAGs), which are synthesized in the syncytiotrophoblast and used as early markers of pregnancy in...

A total of 240 rabbits ( Hyplus(R) ), weaned at 35 days of age, were used for growth rate and health status evaluation. Rabbits were divided into two groups (group S14 and group S12), and fed diets S14 (diet Starch 14%) and S12 (diet Starch 12%) formulated according to the most recent recommendations for rabbit feeding. The study was performed on a commercial farm. The diets were similar in the level of crude protein, fibre fractions and fat, but differed in the level of starch (14.4 vs. 11.9% in the S14 and S12 diets, respectively) and consequently digestible energy (10.0...

Trichobezoars (formations of hair balls that can not pass through the pyloric valve) are responsible of some of deaths observed in Angora rabbirs. A total of 160 trichobezoar deaths corresponding to 28.6% of total deaths were recorded during a reported period of five years. The highest mortality due to hair balls was recorded in 2001 (36.4 %) and was least in 1999 (9.4%). Of the four breeds, the highest trichobezoar death records were obtained in Russian Angoras and the lowest in German Angoras. Trichobezoars occur more frequently in winter months than other months. Besides trichobezoars, other causes of death recorded...

Seven diets were formulated in order to determine the nutritive value of whole maize plant at three stages of maturity by substitution of a control diet (C) with 20% and 40% whole maize plant at early dough, mid-dent and mature stages of grain. A digestibility trial was performed with 74 rabbits. Digestible protein and energy values of whole maize plant at different maturity stages were calculated by substitution and regression procedures. A fattening experiment was carried out with 200 rabbits from weaning (28 days of age) giving ad libitum either diet C or 20% mature whole maize plant. One hundred...

The effects of a reduction in the dietary crude protein (CP) level during the period when lactating does and suckling rabbits share the same feed (from 21 days to weaning at 35 days of age) were investigated for several performance traits. Two iso-energy diets were formulated to contain 18.4 or 16.1% CP and were each given to 55 multiparous rabbit does and their offspring during two consecutive lactation cycles. Type of diet did not affect either feed intake or performance of rabbit does (body weight, fertility, prolificacy, culling rate) and young rabbits (growth rate or mortality before weaning). Accordingly, at...

The first transgenic rabbits were obtained two decades ago by pronuclear microinjection. Several characteristics of rabbit made it the first and classical model for the study of lipoproteins and atherosclerosis. Rabbit models include normal cholesterol-fed rabbits, spontaneous mutants for lipid metabolism and transgenic rabbits. Though most molecular investigations of the cardiovascular system have used transgenic mice, the small rodents do not accurately reflect crucial facets of human cardiovascular physiology, therefore a number of different transgenic rabbit models of hypertrophic cardiomyopathy were created. Transgenic rabbits have been found to be suitable bioreactors for the production of pharmaceutical proteins filling an important...
