Iron deficiency during pregnancy affects postnatal blood pressure in the rat.

Iron (Fe) deficiency anaemia during pregnancy results in an increased risk of perinatal mortality and morbidity and is a significant factor for increased risk of disease in later life. Consequently we have developed a rat model to study the relationship between maternal Fe deficiency and postnatal growth and blood pressure in the offspring. Weanlings were fed a control or Fe-deficient diet prior to and throughout pregnancy.

Effect of feed intake on amino acid transfers across the ovine hindquarters.

Responses in variables of amino acid (AA) metabolism across peripheral tissues to feed intake were studied in six sheep (mean live weight 32 kg) prepared with arterio-venous catheters across the hindquarters. Four intakes (0.5, 1.

Effect of dietary fiber on endogenous nitrogen flows in lactating dairy cows.

The effect of dietary fiber on endogenous N secretion was studied using a 15N isotope dilution technique in four fistulated Holstein cows. Two isonitrogenous diets differing only in fiber (NDF and ADF) content were used in a crossover design. One diet (HF) contained 37.

Effect of feed intake on ovine hindlimb protein metabolism based on thirteen amino acids and arterio-venous techniques.

It has been suggested that protein synthesis in peripheral tissues: (1) responds in a curvilinear manner to increasing feed intake over a wide range of feeding levels; and (2) has a greater sensitivity to intake than protein breakdown. The aim of the present experiment was to test these hypotheses across the ovine hindlimb. Six growing sheep (6-8 months, 30-35 kg), with catheters in the aorta (two), posterior vena cava and jugular vein, received each of four intakes of dried grass pellets (0.

Effects of diet quality on urea fates in sheep as assessed by refined, non-invasive [15N15N]urea kinetics.

The effect of diet quality on urea production, entry into the gastrointestinal tract (GIT) and subsequent diversion to anabolic or catabolic fates was examined in four sheep (mean live weight 49.5 kg). The animals received, in a crossover design, each of two rations, hay-grass pellets (1:1 HG) and a mixed concentrate-forage (CF).
