How to prevent feed waste in chicken house?

Feed cost is the cost of breeding production expenses in the project, accounting for about 70% to 80% of the cost of breeding. Comprehensive links, feed waste is more serious, can account for 10% to 30% of the total amount of feed. Reduce feed waste is one of the main measures to reduce production costs and increase profits.How to prevent feed waste?

Waste in the opening stage

Wrong way: Use powder or broiler feed for the opening stage and feed at once

Correct method: Use Chick Paws to open the feed. Use the feed tray, the edge of the tray should be 2 cm to 3 cm above the bottom of the tray, feed less and add more often, thus can greatly reduce the waste of feed.

Sink detail management

Wrong practice: just add water, never check the sink or water dispenser

Correct practice: in adding water to the water trough, the water trough should be checked frequently to prevent the water trough from leaking and soaking wet material, and if broken and leaking is found, it should be solved as early as possible. The nipple type water dispenser should be frequently observed to prevent the phenomenon of no water or often dripping water. If the water level in the water trough is too high, feeding dry material drinking water, the feed adhering to the chicken’s mouth is easy to be washed away by running water, this alone can waste up to 15 kilograms of feed per chicken per year, the feed is quietly wasted horribly. Therefore, the water level should not be too high, and the depth of water in the trough should be such that chickens can drink water, but it does not affect the drinking water.

The nipple type drinking device is used to effectively prevent chickens from bringing feed into the water trough, causing waste of feed and pollution of the water source.

Feeding trough

If the trough is too small or too shallow, the material will easily overflow and cause waste; if the trough is too large, too deep or placed too high, it will affect the chicken’s feeding and growth and development. According to the age of the chicken, choose the appropriate size of the eaves trough, the trough with a pointed bottom, belly, small mouth structure is good, placed at a height of about 2 cm above the chicken’s back.

The amount of feed added at one time should not exceed 1/3 of the depth of the trough. According to the study, the feed is wasted 45% of the feed when the trough is full; when it is added to two-thirds, 12% of the feed is wasted; when it is added to one-half, 5% of the feed is wasted; when it is added to one-third, 2% of the feed is wasted.

Breeding period quantity

Wrong practice: no limit or wrong restriction of intake.

Correct practice: During the breeding stage of young chickens, feeding should be restricted and fed with feeds of low nutritional content (energy and protein, etc.) instead of reducing the intake of chickens. Restricted feeding can control body weight, delay sexual maturity, enable breeding chickens to reach normal bone development, and reduce the number of small eggs in the initial laying period and large eggs in the late laying period.

• Chickens that are too small and weak should be removed or eliminated before feeding restriction.
• When restricting feeding, it is necessary to prevent malodor, especially in open coops, which requires the selection of quality-assured feed.
• the basic basis of limited feeding is weight, according to the measured weight of the chicken group to determine the amount of feed.

Rodent infestation

A rat can eat 12 kg of grain a year and deface 40 kg of grain. In large and medium-sized chicken farms, the rate of chicks rat bite up to 5% ~ 10%, the eggs eaten by rats can reach more than 5 000 kg, the loss of tens of thousands of kilograms of feed, bite destroyed artifacts loss of tens of thousands of dollars. At the same time, rats are the vector of many diseases.

Rat tracks are occasionally found at night ——50~100 rats.

Rat tracks —–100~500 are often found at night.

Occasionally find rat tracks during the day —–400~1000 pcs.

Rat tracks —–1000 or more are often found during the day.

Rodent extermination method: rodenticide, electric cat, rodent trap, rodent cage, sticky board, etc.

 

Bird damage

Highly pathogenic avian influenza occurs mainly due to the migration of virulent marmots that spread the virus. At the same time birds also feed on the feed, resulting in a huge waste of feed that cannot be assessed.

For breeding areas, feed storage and processing areas, take measures such as fully enclosed feeding or using isolation nets to prevent birds from directly entering poultry feeding sheds and blocking the contact between poultry and wild birds.

Storage and preservation of feed and raw materials

Wrong practice: directly on the ground or simply do not pay attention to the preservation environment.

Correct practice: in the storage of raw materials, storage storage, its bottom should be brick or board pad up to a height of 20 cm, more than 20 cm from the wall, custody of feed as far as possible not to be placed outdoors, must be shaded. For feed placed outdoors, to be covered with rainproof rain cloth or plastic sheeting cover tightly, and often checked. In the summer, the feed storage library to be well ventilated, the temperature should be less than 25 ℃, relative humidity of less than 80% to prevent corn fever, spontaneous combustion of fish meal.

When purchasing feed, not a large number of purchases at one time, so as to reduce storage time, but also to reduce the loss of nutrients. The amount of feed processed at one time, store more than 1 week to ensure that the new feed is always available.

Feed processing, use of waste

In the production process of feed machinery processing, pulling, feeding, etc., because of poor storage management of raw materials, feed raw materials such as: mold, moisture overload, impurities and other factors of corn, insufficient protein content of soybean meal (very common), insufficient calcium content of stone meal and other factors, greatly caused the feed nutrition can not reach the design standard, resulting in potential production performance is not up to standard, is the waste.

Feed processing, do not understand the feeding sequence, mixing time is too long or too short, resulting in poor feed mixing uniformity, resulting in unbalanced intake of nutrients for laying hens, is a potential waste of feed; feed feeding and other links, because the feeding equipment is not scientific, the operation process caused by the feed throwing waste, resulting in feed classification, also resulting in a great waste of feed; feed trough broken leak off material, not only resulting in feed waste, but also Cause feed mold and cause disease.

Beak breaking

Wrong practice: do not break beaks in time.

Correct practice: breaking the beaks of chickens at 7 to 10 days of age can not only prevent future pecking and improve survival rate, but also effectively reduce feed waste and save about 3% of feed. Chickens have a picky eating habit, and unbroken beaks have long, curved, pointed beaks that can easily hook feed out of the trough. The time for chicks to have their beaks broken is generally around 10 days old in the early stages and can be around 12 weeks old in the later stages. If bad habits occur, the second beak break should be done earlier.
