STRUBBE, J. H. AND J. GORISSEN. Meal patterning in the lactating rat. PHYSIOL. BEHAV. 25(5) 775-777, 1980.The present study was undertaken to investigate feeding behaviour of the lactating rat over the day-night cycle. Food intake was recorded continuously in six pregnant and subsequently lactating female rats with 10 pups each. Although there was a twofold increase of food intake during the fi...

Reports of severe enteric disease of unknown etiology affecting lactating mice have appeared in the literature. Clostridial disease similar to that seen in cattle and sheep on high-carbohydrate rations and caused by Clostridium perfringens has been suspected in these mouse outbreaks but has not been isolated from affected mice. The present report describes a severe, necrotizing enterocolitis as...

Intravenous administration of a single dose (20 micrograms) of recombinant interleukin-1-beta to virgin, lactating and litter-removed rats rapidly decreased intestinal lipid absorption in all groups. In vivo, oxidation of [14C]triolein to 14CO2 was also significantly decreased by interleukin-1. In addition, the cytokine decreased [14C]lipid accumulation in the mammary gland of lactating rats an...

BACKGROUND The risk of hypocalcemia after total thyroidectomy is well-described in the literature. Recalcitrant hypocalcemia after thyroidectomy in a lactating woman is uncommon and may require multiple strategies to correct. METHODS We present a case report of a lactating woman with papillary thyroid carcinoma requiring total thyroidectomy and neck dissections. RESULTS Postoperatively the ...

Tumour necrosis factor alpha (cachectin) was administered to virgin, lactating and litter-removed rats, and subsequent disposal of an oral [1-14C]triolein (glycerol tri[1-14C]oleate) load examined. Absorption of the lipid and 14CO2 production were significantly depressed in all three groups. [14C]Lipid accumulation was decreased in carcass, liver and adipose tissue (brown and white) of virgin a...

1. The mechanism responsible for the failure of insulin to activate pyruvate dehydrogenase (PDH) in white adipose tissue in vivo during lactation was investigated. 2. Insulin failed to increase PDH in isolated adipocytes from lactating rats. 3. Insulin binding to plasma membranes from adipocytes was unchanged by lactation. 4. Incubation of plasma membranes plus permeabilized mitochondria from a...

This is the first report of an acute and fatal outbreak of bovine diarrhea virus (BVDV)-2 infection in Israel. The clinical presentation varied with the age of the affected animals with a bovine-respiratory-complex-like syndrome in young stock, and diarrhea and dysentery only in the lactating stock. Enteritis first appeared in one shed of post-parturient cows; it spread for 6 weeks, until at le...

In contrast to nonruminants, forage-fed ruminants normally absorb very little glucose from their feed. However, glucose supply is still crucial for maintenance and productive functions in ruminants, such as growing and lactating cattle. Glucose supply is especially important for the lactating dairy cow because of the demands of milk synthesis for glucose. Glucose requirements of ruminants are l...

The transition from pregnant, non-lactating to non-pregnant, lactating is too often a disastrous experience for the cow. Most of the metabolic diseases of dairy cows milk fever, ketosis, retained placenta (RP), and displacement of the abomasum occur within the first two wk of lactation. In addition to metabolic disease, the majority of infectious disease experienced by the dairy cow, especially...

The breast undergoes extensive changes during pregnancy and lactation that can create diagnostic challenges. This article reviews the anatomy of the breast, breast changes associated with pregnancy and lactation, and breast imaging techniques for pregnant and lactating women. Various benign breast conditions in this patient population also are discussed, such as lactating adenomas, galactoceles...
