Rir chickenare ( Rhode Island Red) the result of cross-breeding between arabic layer chickens & red layer chickens, a type of laying hens that are intended to print domestic chicken documents with production similar to laying hens in general.
Modification of laying hens is to find laying hens that are genetically compatible with the marriage of several other types of laying hens. So in this way it doesn't change the race/strain of the layer and keeps the egg durability high as usual.
Please note that this genetic modification is not intended to be sold for consumption eggs, but to produce free-range chickens or DOC hatching eggs. Because there have been modifications of various layers themselves such as brown, new hampshire, arabic chicken, copper maran and rhode island red (RIR).
With several types of laying hens above combined with deep mating and selection techniques, modified laying hens were born that have various colors such as black, red and so on. It should be noted that at peak production it can produce 90% of eggs and the equivalent of 70% without incubating eggs.
Rir Chicken Characteristics
Physically, rir chickens have various feather colors, therefore it cannot be called only one or two colors. It is based on a combination of mating from different layers of the chicken tribe, not genetic engineering, the animal world's best friend. So don't misunderstand and understand this issue.
The color of the feathers is gray, black brown, black chicken, blackish white, jali and RIR red.
- Egg Production 70-90%
- Egg shell color is similar to chicken
- Adult weight more than 2 KG
- Egg percentage 250-320 eggs/year
Types of Rir Chickens
From this classification there are 2 types that are widely known by chicken farmers. Although physically the difference is not so significant in terms of weight and quality of egg yields.
Rir Chicken Modification
Rir chiken is a type of laying that aims to produce free-range chickens and hatching eggs with a production capacity of between 70-80% and a peak period of up to 90%.
Genetically, Arabic visual modif has a higher Arabic physique, but the weight is much different. Therefore, it is highly recommended to print free native chicken seeds to pursue egg weight and production.
Because there has been a genetic modification so that the arabic gene is weakened as a result the female parent will produce genetic offspring or male lineage. For example with bangkok chicken will be flat with the male.
Blue Modified Rir Chicken
Blue rir chicken is the result of a cross between arabic modif with blue type or the original descendants of copper maran. Thus, the blue color will produce a dominant tiller if it is mated again with a layer of yellow modif and arabic modif.
Based on the track record of farmers who have taken their chicks, the growth is very fast, namely in 2 months it can reach 1.7kg with a low FCR. So we think it's great to develop a super quality local breed.
From the results of the chicks, there can be various shades of feather colors such as gray, brown, black and similar to ordinary free-range chickens. With this quality, marketing of hatching eggs/meat will be easier and the harvesting process will be very fast.
Difference between rir Layer Chicken & Ordinary rir Chicken?
According to Candra Rianto, the main difference between ordinary layer and larmod is physically smaller than larmod/armo. The lower two layers of the regular coat are generally white.
In addition, if I'm not mistaken, the normal layer is a cross between a brown ps layer and a female white ps cross from a combination of several types, one of which is white leghorn.
Generally, ordinary laying eggs are also used as joper brooder and when mated with black males, the offspring are not necessarily black dominant, but mixed together.
