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.

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 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.

How to Improve Chick Survival Rate? These Are the Methods Poultry Farmers Must Master
Chicken brooding is the key to success or failure in the poultry industry; it directly affects the health status, survival rate and feed-to-meat ratio during the growing and finishing stages. Most rural specialized farming households do not pay enough attention to the success or failure of the brooding stage. Barn disinfection: before introducing chicks, the brooding house must be thoroughly and completely disinfected

What are the methods to improve the reproductive rate of porcupines
1. Multiple-mating reproduction method: During the peak estrus period of the female porcupine, after it has mated with the male porcupine in the same breeding pen for 6 hours, place this female porcupine into a spare male porcupine breeding pen to allow it to receive a second mating. After that, raise the pregnant female porcupine separately until it gives birth.

Measures to Improve Reproductive Capacity in Meat Donkey Breeding
I. Strengthen Selection of Breeding Stock. Reproductive capacity is greatly influenced by genetic factors, and the reproductive performance of different breeds and different individuals also varies. In particular, the male donkey has a great influence on offspring, so selecting male and female donkeys with high reproductive capacity is the prerequisite for improving the donkey reproductive rate. For female
