Background: Soil and plant contamination in copper exposure causes chronic copper poisoning (CCP) in animals following the consumption of plants in these soils. Objectives: The present study was carried out on 10 clinically affected copper poisoned cases (in each season) from autumn 2015 to the end of summer 2016, in four seasons in Kerman province to evaluate the seasonal effects of CCP in she...

Securigera securidaca (Fabaceae) or goat pea is growing wild in West Asia, Europe and Africa as an annual herb. In Persian, it is called “Gandeh Talkheh”. The seeds of goat pea are applied in the traditional medicine to treat different dysfunctions e.g., hyperlipidemia and hypertension. This study was done at altitude of 2100 m above sea level. The effects of dietary Securigera securidaca seed ...

The activity of ornithine decarboxylase (ODC), an enzyme associated with cellular growth and protein synthesis, was examined in breast muscle, liver, and intestinal tissues of turkeys during a short-term period of feed withdrawal (FW) and following refeeding. Turkeys from a randombred control line were reared under standard management practices to 3 wk of age in battery brooders. Feed was then ...

introduction: in chick embryo, endodermal component of the liver becomes split into 2 diverticula in a short time. the anterior diverticulum lies to the left of the ductus venosus and the posterior one to its right side. as the liver primordium grows, it is invaded by the embryonic veins. based on the different incubation time periods and evolutionary origin of avian species, various times for ...

I A histochemical reaction has been described which allows the investigator to distinguish between light and dark adapted retinal receptors. The incubation medium employed contained NBT, succinate, TC 199, and a buffer. The reactive process studied has its locus in the ellipsoid of the retinal receptor. Several response characteristics of this reaction have been reported, including the finding ...

BACKGROUND: Several regulatory proteins are involved in Salmonella invasion. The key regulator of SPI-1 (Salmonella pathogenicity island 1 ) is hilA, a transcriptional activator encoded on SPI-1 that regulates the expression of the SPI-1 secretion system. OBJECTIVES: Importance of hilA mutation on S. enteritidis colonization and shedding in layer hens was evaluated in a long-term experiment. ME...

Bacteriophage are viruses that can infect and kill bacteria. A study was conducted to determine if bacteriophage added to drinking water for 1 wk prior to respiratory challenge of broiler chickens with E. coli would provide protection. There were 12 treatments with 2 replicate pens of 10 chicks. The treatments consisted of birds on normal water challenged at 1 wk with either 103 or 104 cfu E. c...

This study was carried out to investigate the effects of dietary putrescine (PUT) on broiler’s response fed low crude protein (CP) diets. A total of 192 male day old chicks were fed with four dietary treatments including two levels of PUT (0 and 0.03%) and two levels of CP (normal and low) with factorial combinations. Weekly growth performance, nutrient digestibility and intestinal morphology (...

Multiple phases of protein synthesis are necessary for the synaptic modifications that consolidate long-term memory. The reconsolidation hypothesis supposes that information in long-term memory becomes labile and subject to change when retrieved and must be reconsolidated into long-term memory. The current study used the protein synthesis inhibitor anisomycin to examine memory consolidation in ...
