Restricted Rearing Methods Broiler Breeders


Restricted rearing methods for broiler breeders

Restricted feeding is to control the growth and development of breeders by artificially controlling the nutrient level, feed intake and feeding time of chickens, so that they can start production in a timely manner.


Restricted Rearing Methods Broiler Breeders

The specific methods are as follows:


1. Time limit method

The main purpose is to control the feed intake by controlling the feeding time of chickens, so as to achieve the goal of weight control and sexual maturity.


(1) Daily feeding limit: feed a certain amount of feed and drinking water every day, or specify the number of feedings and the time of each feeding. This method is less stressful for chickens.


(2) Limit feeding every other day: feed for 1 day and stop for 1 day. Feed the two-day limit on one day. This method is a better method of restricting feeding, it can reduce the impact of competing troughs, resulting in a more consistent group that meets the target weight.

Broiler breeding method

If the daily feed is consumed quickly, only the most dominant chickens will be fed and the rest will starve, resulting in inconsistent growth across the flock. Since a 2-day feed limit is given at one time, both domineering chickens and timid chickens have the opportunity to share the feed. For example, the daily feeding limit is 50 grams, and the feeding amount for two days is 100 grams. This 100 grams of feed is fed once on the feeding day, and the feed is cut off for the rest of the time.


(3) Feeding is limited to two days per week: that is, five days per week and two days off, usually on Sundays and Wednesdays. The feeding amount of the feeding day is to divide the amount of restricted feed in one week into 5 days to feed (that is, multiply the restricted amount of one day by 7 and divide it by 5).


2. The limited quality method

i.e. limiting the nutrient level of the feed. Generally, low energy, low protein or simultaneously reduce energy, protein content and even lysine content to limit the growth and development of chickens. 

In the practical application of broiler breeders, the supply of energy and protein in the diet is limited at the same time, while other nutrients such as vitamins, macroelements and trace elements should be fully supplied to meet the growth of chickens and various organs. developmental needs.


3. Limit method

It regulates the daily, weekly or certain period of feed consumption for the flock. The supply of broiler breeders is generally calculated at 60% to 80% of the free feed intake.


Most breeding companies implement a comprehensive feed restriction program for broiler breeders, which is a combination of various feed restriction methods.


In production, the restricted feeding system should be selected according to the equipment conditions of the chicken house, the goals of breeding, and the advantages and disadvantages of various feeding restrictions, so as to prevent the occurrence of "within the limit of satisfying nutritional needs, the stricter the weight restriction, the better the production performance." one-sided understanding.

What is Microscopic Anatomy and Gross Anatomy?

  The study of anatomy is in existence for about above 12000 years from ancient Greece. Microscopic anatomy and gross anatomy are its substantial parts.  There are 3 broad areas of anatomy as a subject: Human anatomy Animal anatomy i.e. zootomy Plant anatomy i.e. phytotomy     What is Anatomy? Anatomy is the branch of life science concerned with the identification and description of the structures of living things.  This includes information about blood vessels, organs, the skeleton and nerves.  Anatomy is the knowledge about the structure of the bodies of animals and humans.  Gross anatomy includes the study of the main body parts by distribution and observation, and in its narrow sense only applies to the human body. "Gross anatomy" usually refers to the study of large-scale tissue that can be examined without the aid of magnifying devices, while microscopic anatomy refers to the study of ultra-small structures that can be examined and can be seen only with an op

Organic Products Certification

   Organic certification: Abbreviation for organic agricultural product certification Organic certification is the abbreviation of organic agricultural product certification. Organic certification is meant for organic products like  organic foods , organic toiletries, etc. Organic certification is a form of agricultural product certification recognized and vigorously promoted by some countries and relevant international organizations, and it is also one of the certification forms managed by the National Certification and Accreditation Administration of most countries. The purpose of promoting organic product certification is to promote and accelerate the development of the organic industry, to ensure the quality of organic product production and processing, to meet the growing demand of consumers for organic products, to reduce and prevent pesticides, fertilizers and other agricultural chemicals and agricultural waste Environmental pollution, promote the sustainable development of soci

Turnip Rutabaga and Kohlrabi Comparison

  Difference Between Turnip Rutabaga Kohlrabi However, kohlrabi has no taste. If it is not peeled enough, it is easy to eat a mouthful of scum, so not many people eat it.

Some people may accidentally experience the cruelty of the "stock market casino".   What exactly is this fat kohlrabi? The most important thing is, is it delicious? 1.
