“…The Brown Tsaiya is a small-sized (1.4 kg adult body weight) duck and is one of the most prolific laying duck breeds in the world (Tai et al, 1989;Lee et al, 1992). It is native to Taiwan where it is the most popular breed of laying duck.…”

Genetic parameters of traits of interest in ducks and geese are reported. Recent achievements of research, specially to improve the Brown Tsaiya laying duck; the intergeneric crossbreeding in duck; the meat ducks Pekin and Muscovy; the goose reproduction ability; the meat and fatty liver production in geese and ducks were analysed. A linear genetic selection index based on MT-BLUP animal model of breeding values with objectives to maintain body weight, egg weight at current levels, to increase egg shell strength and egg number, used for four generations in Brown Tsaiya laying ducks was evaluated. A seven generations selection experiment was successful in increasing the duration of fertility of Brown Tsaiya female ducks by artificial insemination with pooled Muscovy semen. The genetic parameters of growth and laying traits in a selected Muscovy line in Taiwan were estimated. Favourable genetic trends for body weight at given age, without decreasing egg production, were found in this selected Muscovy line. The selection of grandparent stocks (White Tsaiya and Pekin) for white plumage mule ducks in Taiwan was efficient. The genetic parameters of laying and gosling production traits of Landaise geese and of a White plumage goose strain, bred in two systems, respectively outdoors with natural photoperiodism and in indoors with short daylight conditions were reported. The more advantageous system in selecting for laying traits in geese is discussed. Fatty liver weight was found to be highly heritable in geese and male Muscovy ducks. The genetic parameters of overfed mule duck traits were estimated in the Pekin dam population. It is concluded that future research should focus on biotechnology, quantitative trait loci detection and genome analysis. 509 Breeding and genetics of watefowl: YS. Cheng et al.

“…Laying ducks can also be raised in cages. The egg production of ducks raised in cages is comparable to that of ducks raised on the floor, however, eggshell quality declines with age in cage feeding (Lee et al, 1991), as observed in laying hens (Izat et al, 1985). There was a significant positive correlation (r=0.77) between shell calcium and eggshell quality as assessed using deformation measurements, but a negative correlation (r=-0.50) between shell magnesium and shell quality was noted (Atteh and Leeson, 1983).…”

Three hundred and twelve female Tsaiya ducks from four lines (L1051, L1052, L1053 and L1054) were used in this study to investigate the changes in plasma calcium and inorganic phosphorus levels, blood pH, carbon dioxide partial pressure (pCO 2 ), bicarbonate ion concentration ([HCO 3 -]), and base excess (BE) during laying periods. The results indicated that plasma calcium and inorganic phosphorus concentration at 40 and 50 wks of age were higher (p<0.05) than those at other ages. Significant positive correlation coefficients were found between plasma calcium and inorganic phosphorus levels at each age tested from 20 to 50 wks. Ducks from L1053 showed lower (p<0.05) blood pH, BE and [HCO 3 -] as compared with other lines. Ducks from L1054 had higher (p<0.05) blood pH, BE and [HCO 3 -] than those of other lines showing that there were some differences on blood parameters among lines. Eggshell strength decreased with age up to 65 wks and remained constant thereafter. Egg weight increased gradually from 30 to 60 wks and decreased slightly after 70 wks of age. Plasma inorganic phosphorus level in 40 and 50 wks old birds was positively correlated with eggshell strength, while blood [HCO 3 -] in 40 and 50 wks old birds was negatively correlated with eggshell strength.

“…Behavior observation during the experiment was visually recorded and analyzed by one observer to minimize behavior definition variation induced by different observers. Duck behavior definition was followed and slightly modified from Lee [ 15 ]. Duck behaviors were divided into three main categories: feeding (including feeding and drinking), activities (including preening, frolicking and wagging) and resting (including standing, crouching and sleeping).…”

Objective: The objective of this experiment was to investigate the effects of different colors produced by light emitting diode (LED) on Brown Tsaiya ducks.Methods: A total of 144 female Brown Tsaiya ducks were randomly allocated into three individual cage rearing chambers with different LED illumination colors as treatments. Three different treatments were: i) white color, ii) blue color, and iii) red color. The experiment periods were from ducks 21 to 49 weeks of age, determined traits included i) egg laying performance, ii) feed intake, iii) egg shell breaking strength, iv) egg shell thickness, v) egg Haugh unit, vi) egg weight, vii) serum Estradiol and Progesterone concentration, and viii) behavior pattern.Results: The results indicated that when compared with white and blue color, red color could stimulate ducks sexual maturation and raised the egg laying performance. The red light group was also observed to have the highest feed intake among three treatments. The blue treatment had the lowest egg shell breaking strength and the highest egg weight among three treatments, nevertheless, no significant difference was observed among three treatments on egg shell thickness and egg Haugh unit. The red light group had higher serum estradiol concentration than the white and blue groups, but no significant difference among treatments on the serum Progesterone concentration was found. The results of behavior pattern indicated that red light group showed more feeding and less resting behavior compared to the blue light group.Conclusion: We found a potential of applying red light illumination in the indoor laying duck raising system with positive results on egg laying performance and acceptable egg weight, equivalent egg qualities compared to white and blue light.
