Special feeding and management will have special effects in laying hen production. The following are some special feeding methods abroad:
Adding vitamin C: The results of the Russian study showed that the laying hens were fed with 40 mg of vitamin C per kilogram, which increased the yield of eggs by about 6% in 3 months; 30% per kg of feed at 17 ° C to 27 ° C. Mg of vitamin C increased egg yield by 7% in 48 weeks.
Adding choline: The results of adding choline to laying hens for 44 weeks in the United States showed that the laying rate of laying hens fed with 0.05% choline was 76.2%, the average egg weight was 61.5 grams, and the average final body weight was 1943 g; no choline was added. The laying rate of laying hens is 73.3%, the average egg weight is 58.7 grams, and the final weight is only 1906 grams.
Adding tryptophan: Japanese experts added 500ppm L-tryptophan to the basic diet of laying hens, the egg production rate increased by 9%, the daily egg production increased by 5.5 grams, and the egg production rate after 53 weeks of age. There is still improvement.
Head cooling method: Install a ventilation pipe on the top of each house to supply cold air. As long as the head of the hen is kept cool and the temperature of the hen's head is lowered, the laying rate of the hen can be increased by about 25%.
JUHENG Mini Excavators are products that strike a balance between compact bodies that handle confined spaces and the required level of workability, JUHENG mini excavators and compact excavators are designed to excel in the five attributes that are most important to excavator customers and operators: comfort, controllability, reliability, serviceability and performance.
Mini excavators are a standard piece of equipment on many job sites because they are versatile and highly productive machines. They can be used for digging material, plowing, landscaping work, demolishing small structures and much more.
These compact machines run on diesel and have a range of attachment available depending on your job. They differ from standard excavators mostly due to size, but also because they reduce track marks and top ground damage.
Digger Mini are also favored machines in smaller work sites because of their maneuverability - you can move them forward & backwards similar to a skid steer - and the fact that you can more easily transport them between sites.
