(2001c) also found that feeding 1.65% fish oil to sows through gestation and lactation increased gestation length and reduced birth weight of piglets, while having no effect on litter size. However, pre-weaning mortality was significantly reduced in piglets from sows fed fish oil compared to ...
3.4 Laying, Incubation, and Asynchronous Hatching Female birds ovulate yolked oocytes one at a time, and subsequent deposition of the albumin and eggshell within the oviduct requires many hours. Thus, birds lay single eggs sequentially at daily or longer intervals. Although the length of the interv...

In this experiment,egg shape index,egg weight loss in the incubation,allantoic and amniotic fluid volume were mensurated and analysed. 通过孵化试验,研究了蛋形指数对蛋壳强度、孵化失重、羊水及尿囊液量的影响。 3. For the purpose of studying the relations ofegg shape indexto hatchability and sex ...

These characteristics have implications for population growth both in the wild and in captivity. In the wild, chicks hatch asynchronously, because incubation begins with the first egg (Kuyt, 1995, 1996). In many instances, the older chick kills the younger chick posthatch (siblicide); this ...
