NIEROBISZ, LIDIA SYLWIA. The Effect of Early Post-Hatch Dietary Amino Acid Levels on Satellite Cell Dynamics in Turkeys. (Under the direction of Paul Mozdziak.) Satellite cells are defined as myonuclear myogenic stem cells residing between sarcolemma and basal lamina of the myofiber. Myofiber number is established during embryonic development. Post-hatch and post-natal muscle growth occurs excl...

The present study was designed to investigate the histochemical developmental changes of proventriculus at pre-hatching and post-hatching in northern bobwhite quail periods 11- 15-days addition 14- 21-days post-hatching. composed four tunics is tunica mucosa, sub-mucosa, muscularis, serosa. mucosa lined with simple columnar epithelium height increases age also thickness submucosa filled provent...

Endosomal toll-like receptor-21 and -9 sense CpG DNA activating production of pro-inflammatory mediators with antimicrobial effects. Here, we investigated the induction of antiviral response of in ovo delivered CpG DNA against infectious laryngotracheitis virus (ILTV) infection. We found that in ovo delivered CpG DNA significantly reduces ILTV infection pre-hatch correlating with the expression...

effect of different photoperiodic regimes was evaluated on growth performance and survival rate of the beluga ( huso huso ) prelarvae and larvae. newly hatched prelarvae were stored in 5 round fiberglass 500‑l tank with different photoperiod (24l:00d, 18l:06d, 12l:12d, 06l:18 d, 00l:24d) till 50 days post hatch with three replicates. light intensity was 200 lux during the experiment. feeding wa...

It is not rare that newly hatched chicks remain without feed for about 24 to 48 h before they are placed on farms due to a series of logistic operations. Furthermore, the spread in hatching time can also mount up to 30 to 48 h for late v. early hatchers. In other words, the practice is a complex combination of spread of hatch and delayed feed access. The present study was aimed to investigate t...

The length of the embryonic period varies both among and within species and can affect the individual phenotype in many ways, both physiologically and behaviorally. In chickens, the hatch window may last 24-48 hours (up to 10% of the incubation time), and studies have shown that incubation length may affect post-hatch growth and physiology. However, little is known about effects on behavior. We...

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...
