The response of meat ducks from 15 to 35 d of age to gossypol from cottonseed meal
The objective of this study was to investigate the responses of meat ducks of 15 to 35 d of age to free gossypol (FG) from cottonseed meal (CSM) and to establish the maximum limits of dietary FG concentration based on growth performance, blood parameters, and tissue residues of gossypol. Nine hundred 15-d-old ducks were randomly allocated to 5 treatments with 10 cages/treatment and 18 ducks/cag...
متن کاملEvaluation of alternative schemes for recording body weights in meat-type quails by using random regression.
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...
متن کاملProduction and Reproduction of Egg- and Meat- type Quails Reared in Different Group Sizes
Eggand meat-type quails were reared in groups of different sizes with a fixed female-to-male ratio of 2 to 1 and an area of 158 cm per bird. The aim was to investigate the influence of group size on quail production and reproductive variables. To this end, 360 quails (180 meat and 180 egg-type quails) were assigned in a completely randomized experimental design to one of three treatments with t...
متن کاملEgg laying and egg quality in meat type quails in diallel crosses.
This study aimed to assess egg laying and egg quality in quail lines in diallel crosses. We evaluated 16 genetic groups obtained from crosses of four strains of meat quails (L1, L2, L3, and L4) in a complete diallel. We assessed weekly egg number (WEN), egg yield (EY), egg weight (EW), and Haugh unit (HU) for: 51-80, 81-110, 111-140, and 51-140 days (whole period) old. The general combining cap...
متن کاملComparison of meat quality characteristics between young and spent quails
The aim of this study was to determine the meat quality characteristics of young and spent quail meats. Young quail meat (age 8 week ± 3 days) and spent quail meat (age 8 month ± 3 days) were used in this experiment. Comparison of the proximate compositions, pH, colour, and fatty acid of quail meats showed significant differences (p<0.05). The young quail meat had significantly higher moisture,...
