The effect of in ovo administration of antiadipocyte monoclonal antibodies (MAb) on growth and adipose tissue development in chickens was investigated. In Trial 1, 60 fertilized eggs from layer-type chickens were injected into allantoic circulation with different amounts of MAb against chicken adipocyte plasma membranes (0, 0.05, 0.1, 0.2, and 0.4 mg) on Day 15 of embryogenesis. In Trial 2, 180...

State Agricultural Experiment Stations (SAESs) were established with federal formula funding by the Hatch Act of 1887. In 1955, the Hatch Act was amended and a number of subsequent formula funding programs were consolidated under the USDA Cooperative States Research Service (CSRS), which today is known as the Cooperative Research, Education and Extension Service (CSREES). Currently, all of the ...

Folate transporters, including the reduced folate carrier and the proton-coupled folate transporter, encoded by Slc19a1 and Slc46a1 genes respectively, play important roles in the transport of folate across biological membranes given the hydrophilic nature of folates. Although a number of studies have demonstrated that these two transporters are regulated ontogenetically in mammals, little data...

Changes in circulating levels of prolactin (PRL) and tissue content of PRL receptor (PRLR) messenger RNA (mRNA) in the liver, pancreas, kidney, and gonads (testis/ovary) were measured in turkey and chicken embryos from embryonic day (ED) 21 or ED15, respectively, to 1 d after hatch by real-time PCR. There were no differences between the sexes in chickens or turkeys. Both species had very simila...

Turkeys from two BW groups (which averaged 11.8 and 12.9 kg, Normal and Heavy, respectively) were photostimulated at either 29 or 31 wk of age to determine what effects age-associated changes in hen carcass characteristics, egg weight, and egg components have on subsequent poult weight at hatching during the first 10 wk of production. Carcass measurements were determined from a subsample of hen...

Article history: Received: 17 May 2013 Accepted: 19 June 2013 Available online: 28 Sep 2013 ZJRMS 2015 Feb; 17(2): 22-26 Background: Leptin is one of the possible mediators of ethanol intake. On the other hand, the concentration of total plasma homocysteine (Hcy) is a well-established indicator for the risk of cardiovascular disease and seems to be related to ethanol consumption. So, the aim of...

Researchers are trying to boost the immune system of poultry birds through use natural immune-stimulants including bee venom. There is a scarcity in literature about venom for ovo injection studies. The aim this study investigate effect two levels freeze-dried (BV) (10 and 20 µg/egg) into eggs Alexandria breeder hens at 18-day incubation on hatchability percentage, hatching weight per egg weigh...

The aim of the present study was to investigate how a higher temperature at a comparable period during chicken incubation influences the muscle development and the meat quality in the animals post hatch. Therefore half of fertilized eggs of the broiler genetic Cobb were incubated between ED 7 to 10 at 38.5 °C instead of 37.5 °C (control group). At the day of hatch (Day 21) the hatch rate was 86...

Background and Aim: The exchange of oxygen carbon dioxide (CO2) in the incubator plays a key role embryonic development hatching. This study aimed to effect non-ventilated (NV) intervals during early stage on hatching process. Materials Methods: Hatching eggs (n = 7200) were equally divided into four treatment groups incubated incubators. first group was normal ventilated condition (V) setting ...
