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.

Practical tips for increasing the meat yield in meat rabbit farming
In commercial meat rabbit production, weaned (around 30 days old) young rabbits are generally used, fattened for a short period (that is, fattening of young rabbits), and slaughtered when their body weight increases from about 0.5 kg to 2.5 kg, with the aim of producing more rabbit meat. In commercial meat rabbit production, in addition to looking at the final output, it is also necessary

Effective Measures to Improve the Fertilization Rate in Blue Peafowl Breeding
(1) Select superior, robust individuals to retain as breeding stock. Once adult blue peafowl reach sexual maturity, they can be used as breeding blue peafowl for mating. (2) The timing for grouping male and female blue peafowl together for breeding must be appropriate. If male and female blue peafowl are grouped together too early or too late, it will affect mating. The appropriate

How to improve the overwintering survival rate of forest frogs? These measures must be mastered
The forest frog, also known as the Chinese forest frog or Hasma, is mainly represented in China by the Chinese forest frog (Rana chensinensis) and the Heilongjiang forest frog (R. amurensis), which are widely distributed across the three northeastern provinces of China. Because of the forest frog's unique nutritional and medicinal value, especially its frog oil, it is highly sought after in domestic and international markets

Technical Measures to Improve the Survival Rate in Meat Duck Farming
One, select good ducklings. To purchase ducklings, go to a breeder duck farm with good disease prevention work, where the breeder ducks are strictly vaccinated against fowl cholera, colibacillosis, duck plague, avian influenza, viral hepatitis and other diseases according to the immunization program, and the hatchery's disease prevention conditions meet national regulations.

Aquaculture Measures to Improve the Survival Rate of Two-Year-Old Grass Carp Fingerlings
I. Main Reasons for the Low Survival Rate of Two-Year-Old Grass Carp Fingerlings 1. Pond not cleared or not thoroughly cleared before stocking Thoroughly inadequate pond clearing easily leads to poor pond bottom quality, with large amounts of pathogenic bacteria remaining on the pond bottom. When the weather is erratic as it has been this year and water quality is unstable, this will cause sporadic deaths of the fingerlings.

Methods to Improve the Survival Rate of Grass Carp Fingerlings in Grass Carp Farming
Whether grass carp are raised in monoculture or in polyculture with grass carp as the main species, the water quality must be kept fresh. Feed mainly with green feed and supplement with concentrated feed. Concentrated feed includes bran, beans, and compound feed, etc. During the initial stage of stocking (within 15 days), summer fry should be fed some fresh and tender aquatic plants, such as duckweed and watermeal.

How to polyculture mandarin fish for a high survival rate? Practical methods shared
Mandarin fish is a typical carnivorous fish that only eats live fish and live shrimp. Raising mandarin fish alone requires supporting the culture of forage fish, and the technical requirements are high. If mandarin fish are polycultured in adult fish ponds, the water body can be fully utilized and wild trash fish in the adult fish ponds can be cleared out. In recent years, some farmers have reported

How can the survival rate of artificially bred black carp be improved?
The maturation period of black carp is later than that of silver carp, bighead carp and grass carp broodstock, and the gonads generally struggle to reach the standard for induced spawning at the end of stage IV. Therefore, a method of promoting maturation should be adopted. 15 to 20 days before induced spawning, seine the pond to check the maturity of the broodstock, and promptly give the less mature female and male broodstock
