How to manage mid-production females

The middle period of egg production (301-400 days old) focuses on ensuring high yield of ducks, and strives to maintain the peak period of egg production until 400 days. The concentration of dietary nutrients should be slightly higher than that of the previous period. Each duck should add 22 grams of fishmeal daily, or The batch of 20% protein was fed 150 grams each day, and some green feed and calcium were also fed properly. Each herb feeds 150 grams per day or multivitamins, and 1 to 2% of granular shell powder is added. The light is stable every day for 16 hours. The temperature is maintained at 5 to 10°C. If it exceeds or falls below this standard, adjustments should be made. Routine operating procedures remain stable.

At this time, if the shell is smooth, thick and shiny, it means good quality. If the egg shape becomes longer, the shell is thinner and translucent, there are sand spots, and even soft shell eggs appear, indicating that the quality of the feed is poor, especially if the amount of calcium is insufficient, or vitamin D is lacking, it should be supplemented. If the egg production period is about 2 o'clock in the middle of the night, the egg production time is concentrated, and the production of eggs is neat, indicating proper feeding and management. Otherwise, measures should be taken promptly.
