  • How to Improve Hatchability in Ostrich Farming

    (1) Scientific feeding and management 1. Full-price balanced nutrition. The nutritional level of ostriches is a fundamental factor affecting hatchability. During the breeding period, the metabolizable energy requirement in ostrich feed is 11.3 kJ/kg, crude fat should be limited to 6%-8%; protein should be 18%-24%, while paying attention to the supply of several amino acids (%): arginine 1.04, lysine 0.86, methionine + cystine 0.73, phenylalanine 0.95, valine 1.02; the suitable crude fiber content is 10%, calcium 4%-4.5%, available phosphorus 0.4%, sodium 0.3%, magnesium 0.25%, vitamin E 80 IU/kg. Attention should be paid to the quality of green feed, with appropriate supplementation of pantothenic acid and other trace elements. Research has found that during the breeding season, adult ostriches fed a diet with low energy, high protein and high fiber, and with meat-and-bone meal and blood meal replacing fish meal, can achieve higher hatchability.

  • Reasons for the Low Hatchability of Ostrich Breeding Eggs and Solutions

    The following nine aspects may all cause embryonic development problems, leading to embryo death, weak chicks, stunted development, and high mortality. Researching and improving these triggers will improve hatching results. (1) High inbreeding coefficient affects hatchability. High inbreeding coefficient

  • How to Improve Quail Hatchability? Detailed Practical Measures

    Quail (scientific name: Coturnix coturnix) has a body length of 18 cm, is small and plump, brown with obvious straw-yellow lanceolate stripes and irregular markings; both males and females have reddish-brown and black horizontal stripes on the upper body. The male has a dark brown chin, with the midline of the throat curving upward on both sides to the ear coverts, closely adjoining the buff collar. The buff supercilium contrasts clearly with the brown crown and eye stripe. The female also has similar markings but with less obvious contrast. It often moves in pairs rather than in flocks. It frequently occurs in plains, wastelands, stream sides, and hilly slopes overgrown with dense weeds or low shrubs, and sometimes also moves near cultivated land. It mainly eats weed seeds, beans, grains, berries, tender leaves, and young shoots; in summer it eats large numbers of insects and larvae, as well as small invertebrates. It is distributed in Europe, Africa, and northern, central, western, and southern Asia. In China it breeds from Shache, Yumin, and other places in western Xinjiang to Lop Nur in the east, and overwinters in southern and southeastern Tibet, sometimes also reaching Zhongdian in northwestern Yunnan.
