چکیده

Digestibility markers are commonly used in animal nutrition studies, especially where the total collection of faecal material is not practical. Whilst it is customary to employ this methodology in production animal studies, digestibility trials in dogs and cats traditionally rely on the total collection of faeces. Consequently, there are relatively few reports of the use of inert markers in dogs, and even fewer examples of their validation. The aim of this study was to compare three different digestibility markers in dogs and validate these against digestibility values calculated by total faeces collection. The digestibility markers were evaluated in 12 dogs (4 small, 4 medium and 4 large). The markers were incorporated into a dry extruded diet at the following inclusion levels:

The aim of this research is to compare indigestible internal markers acid insoluble ash (AIA) and acid detergent lignin (ADL) and total collection of faeces (TCF) for apparent digestibility estimation in Caspian horse. Analyses were carried out on wheat straw, alfalfa, barley and maize, for dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber (ND...

Evaluation of inert markers for the determination of ileal and faecal apparent digestibility values in the pig.

A series of experiments was designed to evaluate inert markers employed in studies of ileal and faecal apparent digestibilities of nitrogen and amino acids in pigs fitted with simple 'T' piece cannulas. Trial 1 assessed the palatability of diets containing (a) 5 g chromic oxide/kg, (b) 1 and (c) 5 g titanium dioxide/kg at two levels of feeding. The results indicated that there were slight probl...

C-reactive protein and other markers of inflammation in hemodialysis patients

Background: Hemodialysis patients are at greater risk of cardiovascular disease. Higher than expected cardiovascular morbidity and mortality in this population has been attributed to dislipidemia as well as inflammation. The causes of inflammation in hemodialysis patients are multifactorial. Several markers were used for the detection of inflammatory reaction in patients with chronic renal dise...

Determination of standardized prececal protein digestibility of canola meal in British United Turkeys Big 6 at different ages using multiple linear regression procedure

ABSTRACT- Ninety six 2-week-old British United Turkeys (BUT) Big 6 were assigned to 2 groups (4 replicates of 12 birds each). One basal diet and another one in which 20% canola meal replaced the corn starch in the basal diet were prepared. At 9, 16 and 21 wk of age, four birds from each pen slaughtered for digesta collection. The last two-third segment of the intestine, between the Meckel’s div...
