“…After hatching their leg muscles are more developed than breast muscles. Leg muscles grow very quickly to the age of 2 weeks, and breast muscles to about 7 weeks (Wiederhold and Pingel, 1997;Gille and Salomon, 1998). As a result, the lean content of the breast part, compared with its total weight in the carcase, increases rapidly to about week 7, whereas its percentage in the legs decreases in this period ( Figure 3).…”

The experimental birds were Pekin ducks (352 males and 352 females) reared to the age of 13 weeks. They were fed standard diets ad libitum. Starting from the second week, 21 males and 21 females were slaughtered every 7 d. Their carcases were divided into the following elements: neck, wings, legs, breast and back, which were then dissected into lean, skin with fat and bones. The body weights of one-day-old ducklings were similar (circa 62 g), but at 5 weeks of age the males were heavier than the females, and at 13 weeks of age their body weights were 3537 g and 2994 g, respectively. In 2-week-old ducks 55.77% of lean was located in the legs, 15.91% in the back part, 2.78% in the wings, 12.47% in the neck and only 13.12% in the breast. Considerable changes in the distribution of lean were noted in the ducks aged 7 weeks. Its percentage decreased in the legs (to 29.34%) and increased in the breast and wings (to 36.86% and 10.96%, respectively). Age-related changes in the distribution of skin with fat were smaller. Its percentage increased in the wings, legs and back, and decreased in the neck and breast. Until the age of 7 weeks the percentage of bones was decreasing quickly in the legs and increasing in the neck and breast, compared with their total weight in the carcase.

“…Mallard adults emphasize the wings more, and are capable of long-distance flight (Poole 2005) and vertical aquatic takeoffs without much leg input (Dial and Carrier 2012). This legs-first-wings-second pattern may be widespread across species whose chicks lack elevated refuges or run to water, vegetation, or parents for protection (waterfowl; Gille and Salomon 1998;Dial and Carrier 2012;some wading/shorebirds, Kaufmann 1987;Carrier and Leon 1990;Krijgsveld et al 2001;Bennett 2008;grassland-nesting birds, Sordahl 1982).…”

Wings versus legs in the avianbauplan: Development and evolution of alternative locomotor strategies

2015

Wings have long been regarded as a hallmark of evolutionary innovation, allowing insects, birds, and bats to radiate into aerial environments. For many groups, our intuitive and colloquial perspective is that wings function for aerial activities, and legs for terrestrial, in a relatively independent manner. However, insects and birds often engage their wings and legs cooperatively. In addition, the degree of autonomy between wings and legs may be constrained by tradeoffs, between allocating resources to wings versus legs during development, or between wing versus leg investment and performance (because legs must be carried as baggage by wings during flight and vice versa). Such tradeoffs would profoundly affect the development and evolution of locomotor strategies, and many related aspects of animal ecology. Here, we provide the first evaluation of wing versus leg investment, performance and relative use, in birds-both across species, and during ontogeny in three precocial species with different ecologies. Our results suggest that tradeoffs between wing and leg modules help shape ontogenetic and evolutionary trajectories, but can be offset by recruiting modules cooperatively. These findings offer a new paradigm for exploring locomotor strategies of flying organisms and their extinct precursors, and thereby elucidating some of the most spectacular diversity in animal history.

“…The differences in carcass meatiness between the Muscovy ducks and hybrids, noted in the present experiment and resulting from sexual dimorphism in body weights, are consistent with the observations by RICARD, (1986). GILLE and SALOMON (1998), who compared the growth in breast and leg muscles in ducks, report that the total weight of these muscles in males and females aged 80 days was the lowest in Muscovy ducks, higher -in Pekin ducks, and the highest -in their crossbreeds. This results probably from a lower growth rate of Muscovy ducks in the initial period of rearing, as compared with Pekin ducks.…”

Slaughter value and meat quality of Muscovy ducks, Pekin ducks and their crossbreeds, and evaluation of the heterosis effect AbstractThe studies were conducted on 200 Muscovy ducks, 100 Pekin ducks of the A-44 strain and 200 their crossbreeds (sex ratio: 1:1). The ducks were fed complete commercial diets, appropriate for respective species. Slaughter and slaughter value estimation were performed at the age of: 7 weeks -for males and females of the A-44 strain, 10 weeks -for Muscovy females, and 12 weeks -for Muscovy males and crossbreeds (♂ and ♀). Analysis of the chemical composition, physicochemical properties and sensory properties of meat was made on breast muscles. The heterosis effect on the slaughter value and meat quality was additionally estimated in hybrids. The highest live body weights were reported for Mucovy drakes (4450 g), and the lowest -for ducks from this genetic group (ca. 2400 g). The crossbreeds were characterized by average body weights (2980 g), but the highest relative meatiness (ca. 54%) and the lowest fatness (ca. 20%) of carcasses. The best sensory properties were reported for muscles of ducks of the A-44 strain. A favorable heterosis effect was observed in crossbreeds: positive in relation to meatiness and negative in relation to fatness, undesirable in the customers' opinion. No favorable heterosis effect was noted in most meat quality traits.
