The aim of this study was to evaluate the effect of environmental factor such as month and season on the hatching features of ducks, and to determine the suitable months or season for hatching. For this purpose, the hatching records of different duck breeds raised in ElSerw water fowl farm belonging to Turkey and Water Fowl Breeding Research Department, Animal Production Research Institute, fro...

We conducted a study to evaluate the effects of intramuscular fat levels on the sensory characteristics of duck breast meat. Combining duck genotypes (Muscovy, Pekin, and their crossbreed hinny and mule ducks) and feeding levels (overfeeding between 12 and 14 wk of age vs. ad libitum feeding) enabled us to obtain a wide range of lipid levels in breast muscle. The average values were between 2.5...

West Sumatra has several breeds of germplasm ducks that have good potential for breeding, including Bayang Ducks, Kamang ducks, Pitalah and Sikumbang Janti ducks. This type duck develops in the origin area to produce eggs meat. The diversity performance these is still high. study aims determine various female during starter period. One hundred twenty heads local were used this study. an experim...

______________________________________________________________________________________ Abstract The effects of production system on welfare traits, growth performance and meat quality of ducks were explored. A total of 120 newly hatched ducklings were randomly assigned to three groups: i) floor-reared system (FRS); ii) welfare-reared system (WRS) and iii) net-reared system (NRS) (n = 8 duckling...

Of 4,268 wild ducks sampled in Canada in 2005, real-time reverse transcriptase-PCR detected influenza A matrix protein (M1) gene sequence in 37% and H5 gene sequence in 5%. Mallards accounted for 61% of samples, 73% of M1-positive ducks, and 90% of H5-positive ducks. Ducks hatched in 2005 accounted for 80% of the sample.

Rosin was once widely used for removal of duck feathers in China and is still being used secretly in some poultry processing enterprises. Abietic acid (AA) and dehydroabietic acid (DHAA) are the major compounds of rosin. In the present study, 90 duck samples were collected for investigation of AA and DHAA residues. Abietic acid and DHAA were simultaneously detected in 13 out 40 raw ducks, 8 out...

Twenty-four cecectomized and 24 intact White Pekin ducks were used in two experiments to assess the influence of cecectomy on ME and amino acid digestibility of several feed ingredients for ducks. Corn and soybean meal (SBM) were evaluated in Experiment 1, and bakery meal (BM), red dog (RD), and wheat middlings (WM) were evaluated in Experiment 2. Nitrogen-corrected true metabolizable energy an...

The objective of this research was to evaluate the influence housing system (deep litter [DL] vs. deep with swimming pond [DLSP]) on productive performance, carcass traits, body temperature, blood profile, and element composition femur tibia in Muscovy ducks. At 5 weeks age, sexed ducklings (264) were divided into 4 equal groups according gender (drakes ducks). as follows: 66 drakes/DL, drakes/...
