Comparision of Direct and Indirect Response to Selection for Breast Weight in Japanese Quail
This study was carried out to investigate the direct and indirect responses to selection for four-week body weight (4 week body (wk BW)) and four-week breast weight (4 week breast weight (wk BRW)) and to determine the genetic contribution of reminder founders to the last generation. A total number of 351 birds were equally allocated to three lines, including two selected lines (S1 and S2 for BW...
متن کاملThe Relationship between Egg Size and Chick Size in the Laughing Gull and Japanese Quail
ABsT•CT.--Variation in the water, lipid, and nonlipid dry matter of eggs and newly hatched chicks of the Laughing Gull and Japanese Quail was related to variation in the size of the egg. Egg contents of the two species were, on average, very similar. Yolk size varied in direct proportion to egg size, but in the quail large eggs contained disproportionately low levels of lipid and high levels of...
متن کاملResponse to Selection for Body Weight in Japanese Quail (Coturnix coturnix japonica)
The present studyinvestigated the impact of selection for body weight (BW) on productive performance, predicted BW and genetic improvement of related traits in Japanese quail. Base population, selected parent and F1 progeny were tested. Pens and cages were used for rearing and breeding. A total of 240 birds in two successive generations, 27 sires and 54 dams (as selected parents) were used. Bod...
متن کاملThe effect of parental age and egg weight on fertility, hatchability and day-old chick weight of Japanese quail (Cortunix cortunix japonica)
The study was carried out to determine the effects of the parental age and egg weight of Japanese quail on the weight of one day old chick, fertility and hatchability of incubated eggs. Three hundred and sixty Japanese quail eggs were obtained from 22 and 36 weeks old quails. The eggs were weighed and grouped into 2 categories: Light (7.5-9.5g) and Heavy (9.6 – 12g). The weight of the chicks we...
متن کاملEffects of Maternal Body Weight, Some Blood Parameters and Egg Quality Traits on Fertility, Hatchability and Chick Weight of Japanese Quail
A total number of one hundred and fifty-three females and males of Japanese quail at 14 weeks of age were used with sex ratio 2 female / 1 male to study the effect of maternal body weight, some blood parameters and egg quality traits on fertility% (F%), hatchability% for total and fertile eggs (H/TE % and H/FE %), and chick weight (CW). Birds classified into three groups (light, medium and heav...
