Guys transmitted given that projected 53,000 kcal to egg throughout the incubation, the same as 5 kg out-of lipids (approximately 18–20% of the lbs). Those people thinking are probably a small overestimate of the energy necessary for incubation while the i believed that incubation begins at the day you to and all eggs is applied at the same time and generally are equally included in a man (aforementioned presumption is obviously violated inside the large handbags). Because rhea men barely log off this new nest to pass through, our imagine will bring an approximation of your own websites energetic cost of incubation. New estimated energetic cost having rheas is much like you to mentioned in the Emus (Dromaius novaehollandiae), an alternative ratite kinds where in actuality the men works most of the incubation. Men Emus shed 7 kilogram (regarding 17–20% of the pounds) throughout 56 days of incubation ( Dawson mais aussi al. 1984). Furthermore, Brownish Kiwi (Apteryx australis) guys destroyed ?23% of its body weight while in the 91 days of incubation, though in this variety incubation was partly shared with ladies ( Taborsky and you will Brugger 1994). 자세히 보기
