the present research was conducted to estimate the dietary lysine (lys) requirements of growing quails as based on performance and carcass constituents parameters at 3 to 24 d of age. the experiment was carried out in a complete randomized design arrangement the 6 dietary lys levels; 1, 1.15, 1.30 (nrc 1994), 1.45, 1.60, and 1.75 %, from 3 to 24 d of age. a dose-response diet mainly based on co...

The transmission of H9N2 influenza viruses to humans and the realization that the A/Hong Kong/156/97-like (H5N1) (abbreviated HK/156/97) genome complex may be present in H9N2 viruses in southeastern China necessitated a study of the distribution and characterization of H9N2 viruses in poultry in the Hong Kong SAR in 1999. Serological studies indicated that H9N2 influenza viruses had infected a ...

The objective of this study was to determine the impact different ambient temperatures on egg production and hatching parameters in Japanese quail. Sixteen weeks old male female quail were assigned 10 cages as 1 5 females. Quails housed a poultry yard belonging Faculty Agriculture. reared under 16 hours’ light 8 dark photoperiod. During study, water food freely available ad-libitum. Regularly e...

This study compared the cholesterol levels and shell pigments (protoporphyrin biliverdin) of chicken (conventional organic), quail, pheasant, goose eggs. The material for was (organic system - Lohmann Brown conventional HyLine Brown) eggs, quail (Coturnix coturnix japonica), (local), pheasant (Phasianus colchicus) eggs homogeneously selected with a subjective scoring. High-performance liquid ch...

Perchlorate ion interferes with thyroid function by competitively inhibiting the sodium-iodide symporter, thus blocking iodide uptake into the thyroid gland. In this study, the effect of perchlorate exposure on thyroid function and thyroid-responsive gene expression were examined in (1) embryos from eggs laid by perchlorate-treated Japanese quail hens and (2) perchlorate-treated young Japanese ...

The mesencephalic and rhombencephalic levels of origin of the hypobranchial skeleton (lower jaw and hyoid bone) within the neural fold have been determined at the 5-somite stage with a resolution corresponding to each single rhombomere, by means of the quail-chick chimera technique. Expression of certain Hox genes (Hoxa-2, Hoxa-3 and Hoxb-4) was recorded in the branchial arches of chick and qua...

AIM The present study was conducted to evaluate the performance of gray, brown, and white varieties of Japanese quail (Coturnix coturnix japonica) with respect to body weight, egg production, and egg quality traits in the coastal climatic condition of Odisha. MATERIALS AND METHODS A total of 500-day-old straight run Japanese quail chicks of three varieties, viz., gray, brown, and white were r...

Data from 8759 meat-type quails from the UFV1 strain and 9128 from the UFV2 strain were used to assess the possibility of reducing the number of body weight records in genetic evaluations. The evaluated animals were weighed weekly since hatching to the 6th week of life, with up to 7 records of body weight for each bird. The data were evaluated by random regression models, with 9 alternative sch...
