Broiler chicks are transported to production sites within one to 2 d post-hatch. Possible effects of this transportation are poorly understood and could vary among chicks from breeder flocks of different ages. The aim of the present study was to investigate the effects of transportation duration and parental flock age on chick welfare, productivity, and quality. After hatch in a commercial hatc...

Measurements were made of the surface areas (As) of the skin and gills of larval and juvenile walleye Stizostedion vitreum with a body mass (M) of between 2mg (1 day post hatch) and 2.3g (98 days post hatch). The skin, with a relative surface area (As/M) of approximately 8500mm2g-1, accounted for more than 99.9% of the total surface area (skin + gills) at 1 day post hatch. The relative area of ...

Background: The Endothelial PAS domain-containing protein 1 (EPSA1) is the key transcriptional regulator of hypoxic response and Vascular Permeability Factor (VPF) is an important growth factor for vascular development and angiogenesis. OBJECTIVES: In the present study, the levels of the EPSA1 coding gene and VPF transcripts were evaluated during Larval development of Beluga, Huso huso. METHODS...

The present study was aimed to investigate the mechanism underlying the influence of maternal low-protein (LP) diet on offspring growth in the chicken. One hundred and twenty Chinese inbred Langshan breeder hens were allocated randomly into two groups fed diets containing low (10%, LP) or normal (15%) crude protein levels. Low dietary protein did not affect the body weight of hens, but signific...

Immunohistochemistry and polymerase chain reaction (PCR) were used to test for the presence of avian leukosis virus (ALV) J viral antigen gp85 and proviral DNA, respectively, in various tissues (adrenal gland, bone marrow, gonad, heart, kidney, liver, lung, pancreas, proventriculus, sciatic nerve, spleen, and thymus). Tissues were collected from 32-week-old commercial meat-type and Avian Diseas...

Guanidinoacetic acid is formed from Arg and is the immediate precursor to creatine (Cre). A study was conducted to determine the ability for GAA to spare Arg in broiler chicks fed an Arg-deficient practical diet. A common basal diet (0.84% digestible Arg) was supplemented with combinations of Arg (0 or 0.16%) and GAA (0, 0.06, or 0.12%) to form a 2 × 3 factorial arrangement of dietary treatment...

OBJECTIVES Dipeptidyl peptidase IV (CD26; E.C. 3.4.14.5) is plasma membrane glycoprotein exopeptidase. There are no data on both phenotypic or genotypic expression and polymorphism of DPP-IV in Indian type-2 diabetic patients. Therefore we estimated the dipeptidyl peptidase IV (DPP-IV) levels in Indian type 2 diabetic population. METHODS Selection of study group was as follows: 1. Twenty seve...

BACKGROUND Acute postprandial hyperglycemia is an important affector for atherosclerosis in subjects with glucose intolerance. We analyzed the relationship of brachial-ankle pulse wave velocity (baPWV) with fasting and post-challenge plasma glucose levels according to different time points during oral glucose tolerance test (OGTT). METHODS In 663 subjects with fasting hyperglycemia, 75 g OGTT...
