Feeding meat ducks, feed costs often account for about 82% of the total cost of feeding. Therefore, saving feed is a key measure to reduce the cost of feeding ducks and increase economic efficiency. Now we introduce several ways to save feed for breeding meat ducks. Breeding varieties are excellent The excellent meat ducks have high genetic potential, high growth rate, strong disease resistance, high utilization of feed, and the same age, consumption of the same amount of feed, and their weight gain is greater than that of degenerated varieties. Ducks are much faster. The ambient temperature should be suitable The suitable growth temperature for meat ducks is 12°C to 24°C, in which ducks can fully and effectively use feedstuffs. Therefore, it is necessary to create conditions as much as possible, such as summer shelters and other measures to keep warm or cool, in order to increase feed remuneration. Balance the diet Because all poultry are “eat by energy,†feed intake is low when the energy level of the diet is high, and feed intake is high when the energy level of the diet is low. Therefore, the proportion of protein and energy in the meat duck's feed must be balanced. Otherwise, the consumption of feed increases, resulting in the waste of certain nutrients. For example, diets with low energy and high protein waste protein as energy consumption. Feed should be fresh and kept properly One is that raw materials must be fresh. The second is to match the material to be grounded, ground feed, feed should be stored in a ventilated, dry place away from light to prevent oxidation of fat in the feed, VA, VE destroyed. Place a layer of moisture-proof material between the feed and the ground to prevent the feed from becoming contaminated and moldy. Mildew feeds are likely to cause poisoning in meat ducks, pull maggots, etc., thereby reducing feed utilization. In addition feed and duck houses should pay attention to pest control, rat damage and so on. Timely slaughter Meat ducks are suitable for slaughter at 40-48 days, because meat ducks gain weight and feed rewards have reached a peak. After 50 days of age, the weight gain of ducks has decreased, and feed rewards have decreased. Reasonable use of additives Nutrient additives such as minerals, vitamins, and amino acids are necessary. Other non-nutritive additives are also helpful in improving the growth rate and feed utilization of meat ducks. Such as probiotics, enzyme preparations, organic acids, peptides, etc., have a significant effect on increasing meat weight gain and feed utilization. Feed shape and adding method should be reasonable Generally do not feed the original food, the original grain smash, with the full price of the granularity of the material, according to the duck's age is different, but not too broken, otherwise it is easy to fly and cause waste. When you add materials, you can't save time and add too much at once. The structure and height of the trough should be appropriate, and the trough should be repaired in a timely manner to prevent waste caused by leakage.
Household Electric Wheelchair is an important Household Medical Equipment for the wounded, sick and disabled at home for rehabilitation, turnaround transportation, medical treatment, and outings. The Electric Wheelchair not only meets the needs of the physically disabled and the disabled, but more importantly, it is convenient for family members to move and take care of them. Patients, so that patients with the help of wheelchairs for physical exercise and participation in social activities.
Ordinary wheelchairs are generally composed of a foldable frame, front and rear wheels, left and right knee pads and footrests, left and right detachable armrests, handle brakes, seats, backrests with medical imaging data bags, bedpans, urine bag hooks, and electric standing. The hand-crank Rehabilitation Electric Wheelchair adds a hand-crank device on the basis of the ordinary wheelchair. On the basis of ordinary wheelchairs, the electric wheelchair adds an electronic power assist system, which reduces the physical exertion of the user. Based on the Electric Wheelchair, Folding Hospital Wheelchair adds positioning movement, standing movement, remote control movement and related Internet + assisted living.
