development, traditional dairy calf management programs have restricted the amount of liquid feed pre-weaning to about 10% of birth weight.[1] However, current research is focusing more on the effects of elevating the plane of nutrition for pre-weaned dairy calves. By increasing the volume of liquid fed pre-weaning to about 20% of birth body weight, the results have been higher average daily ga...

Calves were fed five different test meals: whole milk, skim milk, 3% whole casein solution, 3% whole casein in simulated milk ultrafiltrate, and whey. The digesta leaving the abomasum before feeding and during the first 7 postprandial hours were collected by fractions. After precipitation with 12% TCA, the amino acid compositions of the sediments and the supernatants were determined and compare...

1. The relations between food intake, reticulo-ruminal motility and abomasal digesta outflow were investigated in ewes receiving lucerne (Medicago sativa) v. orchard grass (Dactylis glomerata) hay. Abomasal digesta outflow was recorded continuously by means of an electromagnetic flowmeter probe inserted into a duodenal T-shape cannula and the motility using strain-gauge force transducers. Volum...

Introduction: Sodium hydrosulfide (NaHS) has shown to enhance the gastric emptying rate in normal rats but till now its effect on gastric emptying of food stuffs in diabetic rats was not investigated. Therefore, this study designed to determine the role of an oral administration of NaHS on gastric emptying rate (GER) of glucose, albumin and olive oil in gastroparetic and normal rats. Methods: T...

1. The relationship between protein content of abomasal digesta and abomasal secretion of acid was studied in sheep fitted with re-entrant cannulas in the proximal duodenum. 2. A close relationship was found between the rate of passage of protein through the abomasum and acid secretion, both after varying the protein content of the rations supplied, and after direct introduction of proteins int...
