Changes in Conformation and Walk Kinematics of Suckling and Weanling Warmblood Foals
The objectives of these two studies were to characterize normal growth and resultant changes in conformation and walk kinematics of warmblood foals. The first study quantified linear and angular conformation changes of 13 warmblood foals during the first 9 mo of growth. An objective photographic …

Age-related differences in taste aversion learning: preexposure to the conditioned stimulus through suckling
… Norvegicus) were exposed to saccharin through suckling dams whose drinking water had been adulterated during lactation. Behavioral evidence is reported that the saccharin penetrated the milk and was detectable by the pups. Preexposure to saccharin did not influence the effects of taste aversion …

Intestinal Development and Gene Expression of Piglets Suckling Sows Transgenic for Human Insulin-Like Growth Factor-I
We have shown that piglets suckling IGF exhibit structural and functional changes similar to those observed in piglets receiving formula supplemented with IGF-I. The location and timing of the response to IGF-I differs from previous studies. Insulin like growth factor-I appeared to act via the type …

Effects of Maternal Iron Deficiency During Reproduction on Phagocytosis, Antibody Formation and Cell Growth in the Suckling Rat (Immune Response)
The effects of maternal dietary iron deficiency during reproduction on the development of the immune response in offspring were investigated. Pregnant Sprague/Dawley rats were fed one of three diets throughout gestation and lactation: 6 ppm iron (severe anemia), 12 ppm iron (moderate anemia), 250 …

Carnitine and Altered Lipid Metabolism in Iron-Deficient Rats Pre- and Postweaning (Ketogenesis)
… thesis was that severe iron deficiency in the suckling rat impairs the iron-dependent synthesis of carnitine, thereby shunting long-chain fatty acids away from oxidation and ketogenesis into triglyceride synthesis increasing triglyceride levels in serum and liver. The rationale for carnitine …

Acute and Chronic Effects of Artificial Rearing on Rat Genioglossus Muscle
In most mammals, nutritive suckling is critical during the early neonatal period. The genioglossus (GG) muscle in rat plays an important role in protruding the tongue for efficient suckling. The purpose of this study was to examine the contractile properties and myosin heavy chain (MHC) phenotype …

Contribution of the Adrenal Glands to Postpartum Anestrus in Suckled Cows
Suckling prolongs the postpartum anestrous (PPA) period in postpartum cows while inducing hypersecretion of adrenocorticoids. Hyperadrenocorticism affects reproductive function in cattle as well as in many species. To evaluate the role of adrenal glands in suckling-induced PPA in cattle two …

The Effect of Copper and Zinc Source on Pre-Weaning Performance of Cows, Health and Performance of Suckling Calves, and Post-Weaning Feedlot Performance, Carcass Composition, and Meat Quality of Calves
<p>During gestation an elevated level of nutrient intake is required by the cow in order to meet the requirements of the maturing fetus and if these requirements are not met, changes in fetal development can occur. However, little is understood about the effects of gestational manipulation of …

Rabies virus soluble antigens : a biochemical and biophysical study of the major antigen of rabies virus.
… several antigens demonstrable in rabies-infected suckling mouse brains. The biochemical and biophysical properties of the antigen were studied with a view to elucidating its contribution to the intracellular synthesis and the structure of the virus particles. Extracts of normal and infected …

The early origins of obesity: the importance of prenatal vs postnatal environment.
… maternal cafeteria diet during the prenatal and suckling periods on the metabolic outcomes of the offspring, specifically body weight, fat mass and the expression of key adipogenic and lipogenic genes at weaning, in early adolescence and in young adulthood using a cross-fostering approach in a …

Developmental Regulation of the Expression of Nutrient Transporter and BrushBorder Membrane Hydrolase Genes in the Small Intestine of Piglets
… seven sows were killed at birth (d 0), during suckling (d 1, 3, 7, 14, 21) and postweaning (d 22, 24, 28, 35), and intestinal segments (duodenum, jejunum and ileum) were collected. The mRNA abundance was determined by Northern blot using specific cDNA probes for three disaccharidases …

Managing the lactating sow to stimulate lactation ovulation
… investigated were focused on: reducing the suckling input to the sow through split weaning or low-confinement alternative lactation housing; and fence, or full physical, boar exposure. The importance of a reduced suckling input was demonstrated in Chapter Two. The proportion of sows …
