1. Dry matter and crude protein (nitrogen x 6.25) digestibility of four poultry diets determined by an in vitro method using the intestinal fluid of pigs was significantly correlated with corresponding in vivo digestibility values obtained with hens. 2. The intestinal fluid could be lyophilized and stored for at least 35 d without losing its activity on digestion.

This study aimed to identify chemical composition of Thymus kotschyanus essential oil (TKEO) and to evaluate the effects of different doses of TKEO on in vitro gas production, fermentation parameters, acidosis and protozoal population using a completely randomized design with four replicates. Two diets (D1: 100% forage and D2: 30% forage+70% concentrate) were incubated with buffered rumen fluid...

1. The use of a nylon-bag technique for pig feed digestibility determination was studied. Bags, measuring 25 x 40 mm and containing feed samples, were introduced into the pig gastrointestinal tract through a duodenal cannula, and recovered in the faeces between 23 and 69 h later. The disappearance of organic matter and crude protein (nitrogen x 6.25) from the bags was compared with in vivo appa...

Advances in imaging and cell-labeling techniques have greatly enhanced our understanding of developmental and neurobiological processes. Among vertebrates, zebrafish is uniquely suited for in vivo imaging owing to its small size and optical translucency. However, distinguishing and following cells over extended time periods remains difficult. Previous studies have demonstrated that Cre recombin...

The spatial variation in central retinal function determined from mfERG was compared to co-localised measurements of cone density in two normal subjects. Individual cone cells in the parafoveal region of the retina were identified from 1 degrees x1 degrees images of the photoreceptor mosaic using a modified Heidelberg retina tomograph (HRT). The variation in cone density compared well with prev...

Two trials were conducted to determine the adequacy of ADIN as an indicator of N digestibility. In Trial 1, eight nonforage plant protein sources were heated at 150 degrees C for 90 min in the presence of xylose (12.8% of CP, DM basis) to produce heat damage. Thirty-four wethers (average BW 40 kg +/- 9.9) were used to determine the effect of heat on N digestibility. Differences in ADIN were evi...

insulin-loaded biodegradable chitosan nanoparticle was prepared by the polyelec-trolyte complex formation method. the prepared nanoparticles were in the size of 110 nm and had high entrapment (91.0%) capacity. the transdermal nanoinsulin was characterized by in vivo hypoglycemic effects. plasma glucose was decreased to the range of 80.34 to 96.74 mg/dl, and insulin levels were increased to the ...
