Sources of protein in broiler livestock is most important in corn, soybean meal, rice bran. But several studies The use of fermented feed with EM-4 leads to an increase in protein digestibility of feed, protein content of meat and weight gain of broiler chickens.

The use of EM-4 with a concentration of 15% starter solution in the feed is the most effective mixture for improving protein digestibility of feed, meat protein content and weight gain of broiler chickens, thus improving feed quality and feed efficiency.

good luck

You should use barley..

The protein sources for commercial broiler are Soybean meal and animal protein powder, because the breeding companies selected the genetic make up for its potential to digest and metabolization ability of these sources.

If you mean nutritive value of which protein sources you first of all used soybean meal because in the first values of biologically values. Other hand for low cost of diet you may be training canola mead or other sauces.

hi

n poultry nutrition, most attention is given to protein products, due to the importance of protein as a major constituent of the biologically active compounds in the body. It also assists in the synthesis of body tissue, for that renovation and growth of the body. Furthermore, protein exists in form of enzymes and hormones which play important roles in the physiology of any living organism. Broilers have high dietary protein requirements, so identification of the optimum protein concentration in broiler diets, for either maximizing broiler performance or profit, requires more knowledge about birds' requirements for protein and amino acids and their effects on the birds' growth performance and development. It also requires knowledge about the protein sources available that can be used in poultry diets. The broad aim of this review is to highlight the importance of some of the available high-quality specialized protein products of both animal and plant origins which can be explored for feeding broiler chickens. Minimization of the concentration of anti-nutritional factors (ANFs) and supplementation with immunologically active compounds are the main focus of gut health-promoting broiler diets. These diet characteristics are influenced by feed ingredient composition and feed processing. The general hypothesis is that these protein products are highly digestible and devoid of or contain less ANFs. Feeding these products to broiler chicks, especially at an earlier age, can assist early gut development and digestive physiology, and improve broiler growth performance and immunity.

Fish meal 

Soybean meal is the best protein sources for broiler production but in addition, if  you have availability to good quality fish meal, then you can use in combination with soybean  meal to obtained better harvest. You will lots of literature on this aspect.     

Depending on your location and availability or cost of feedstuffs, preferably use soybean meal plus some fish meal, meat & bone meal or casein. You may also use cotton seed meal, sunflower seed meal or related vegetable oil seed meals, if fiber level permitting.

As Ondieki Mentioned it really depend on the location and the availability of that source, most of the time soybean meal, fish meal, meat and bone meal and sunflower meal are regularly used in the poultry diet

Sources of protein in broiler growing is most important in corn, wheat,  soybean and sunflower meal

Its depend on the local availability of the sources, and usually soybean meal, fish meal, GNC and sunflower cake may be used as protein sources. . 

Fishmeal (Silver fish), Cottonseed cake and Sunflower cake are the main sources of proteins commonly used in Uganda. However, silver fish although it is rich protein (over 50% CP) is very expensive and used for human consumption as well.  There is need to search  for alternative protein sources which are less costly.

In Nigeria most often used  available protein sources includes soybean meal, groundnut cake as vegetable protein sources and fish meal  as animal source.

Broilers have high dietary protein requirements. Therefore, identifying sources and optimum protein concentrations, contents of balanced amino acids and their digestibility is crucial. Generally, based on their availability and cost following animal and plant sources can be used: soybean meal, cottonseed meal, Beans/Peas, Rapeseed, sunflower meal, Fish meal, meat and bone meal.

In the formulation of poultry feed traditional sources are used or not, depending on the type of farming or system used. There are many results with the use of soybeans, fishmeal (in low concentrations due to the smell and flavor left in the meat), sunflower meal, peanuts, yeasts, fishery residues, slaughterhouse waste, vignes, feather meal And flour from hatching plants, among others.

usually soyabean and sunflower meals

In Zimbabwe we mainly use soya bean and to a relatively small extent sunflower meal and cotton seed cake

Generally, soya bean uses as the plant protein source  and some times you can use the protein concentration as animal protein source  with soya bean

Depending on availability or cost of feedstuffs, soybean meal is a good source.

thanks for all

Plant source - Soybean and the animal source - Fish meal

In feed formulation for broiler you can use the protein concentration with soya bean as animal protein source.

Hi Haifa

In Argentina we have a lot of soya, so we are using different options in feed formulations: soya bean, soybean meal, extruded soya bean, soybean expeller. Also 3-8% of meat and bone meal is very usual in the feed for poultry, which is the first one in my country. 

this depends the cost and availabilty of the protein sources. but mostly people use Soybean as protein source but canola meal, sunflower meal, rapeseed meal, corn gluten meal are good altenatives. animal protein sources can  also be used.

Regards

Partha

The most important protein source in my feed formulated was soya bean.

Hi Haifa,

             here in Ghana the main protein source in most broiler formulations is Soya bean. A few farmers may occasionally supplement with fishmeal as well but not very popular. In very few instances copra cake, and palm kennel cake.

soya bean meal is the most appropriate protein source for broiler because it has good amino acid profile as compared to other plant protein sources.it is also processed,which reduced concentration of anti nutritional factors like phytate that inhibit bioavalability of nutrient present in the plant...other sources include rapeseed meal and animal sources like maggot meal,bonemeal,fish meal and the likes

Thank you for all

The best plant protein for broiler, is soybean meal and you can also add fish meal in combination with plant protein sources and/or alone depends on the availability and price of the ingredients. The basic idea of ration formulation is to produce good balance of nutrients in the ration with minimum cost .     

Thanks  for all

In addition to the Soybean meal, for young chick Corn gluten meal is an ideal feed ingredient, because of the high content of digestible Valine.   

Soya bean meal is the most common and appropriate source of protein for broilers as it has a balanced essential amino acid profile and free from ANFs....Corn / Maize Gluten Meal, Meat and Bone Meal and Rape Seed Meal are other sources of protein for broilers...

I am agree with Selvam. 

Thanks for your recommendation, Dr Nathu Ram Sarker...

Soybean meal.

Hi

Soya bean meal is source of protein for broilers, as well as, animal proteins.

Regards.......

Hi DR.

The use of fermented feed with EM-4 leads to an increase in protein digestibility of feed, protein content of meat and weight gain of broiler chickens.

Hi Dr.

location, availability and cost were determined the kind of protein which used but remain preferably used soybean (44-48%), wheat (13%), corn 99%), sometimes used fish,meat, blood,ex.... and you may also use, sunflower seed meal, cotton seed meal and related vegetable oil seed meals.

I am agreed with the answer of Mr Hassan Hammadi. The ration formulation of broiler is usually made plant protein like soybean meal based on price and availability. You can good use best quality fish meal for more balancing the amino acids.

Soya bean meal.

Good quality fish meal is a nice source. But beware of using it in grower/ finisher diets because of smell.   

Maize gluten meal has a good AA profile, especially quite high methionine. Combining it with soya can give good results.

We also use a lot of sunflower seed meal in Russia

Soybean is a best protein source , in addition add some animal protein sources for more balancing of amino acids in the ration, depending the availability and price of the ingredients. .

I think, soybean meal a best protien source.

Greeting

For more amino acids balance, with soybean meal , fish meal may be added based on availability and cost effectiveness of the ingredients.

Animal protein sources like fishmeal (over 50% CP; over 5% lysine) are best because they have less fibre and therefore are easily digested by broilers. However, plant protein sources such as soybean (roasted) meal are equally good.

Soybean, Fish meal, meat and bone meals, , cereal by-products, oil seed meal (sun flower) depending on availability. The first three once are the best source of quality protein for poultry (broilers).

The things to consider in selection of protein source for broiler:

growth phase, e.g. starter or finisher.

Amino acids profile (Be keen onlimiting ones)

availability.

Fish meal and soybean meal are the most utilised but also most expensive. Alternative options should be considered

Soybean Meal, fish meal, bone meal.

Broilers are efficient feed converters . they need high energy and protein diet. When we are formulating a diet for broiler we need to see the protein quality . that means the amino acid profile. We have to make sure that the diet contains critical AA, laycine and methionine .

Soybean meal is the main source and partly corn gluten.

Animal protein sources such as fish meal but with some disadvantages like the appearance of fish odor in chicken meat....ext. therefore we Preferred use Soybean meal which contain 44%_48% proteins.

Soybean meal mainly used as protein source in broiler ration and sometimes high quality may be used in regard to availability of a particular ingredient. .

an update maybe maggot (insect meal).

In Bangladesh, Mainly Soybean meal used as a protein source in Broiler ration because it contains more than 40% protein and comparable cheap to other ingredients and available.

Soybean meal is the best among other protein source

Soyabean meal and fish meal

Now-a-days mostly soya bean meal and maize gluten meal are used as protein source in broiler in India

Soybean meal; corn gluten meal; animal proteins if allowed.

Nowadays, with increasing area of planting Sesame and production in Egypt we can added partly sesame meal as a protein source.

Many scientists/ Nutritionists have answered. As a protein supplement soybean meal + synthetic amino acids is the best. However to reduce cost of protein in poultry & pigs diet combination of protein supplements can be used to harness complementary effect.

The best protein source is soybean meal because the genetic selection and crosses in the breeding companies based on this source

Actually, based on availability where I am working or living we have to select the best ingredients as protein sources and considering cost also. As a Scientist and nutritionist, if plant proteins such as soybean meal, Sesame cake, Ground nut cake, sunflower cake etc are available and assess the comparison of cost which ingredient give me more balanced in all nutritional component such as protein, in amino acids balance, ME we have to select for ration formulation. In major ingredients, if you think that you have to Omega 3 fatty acids rich eggs or meat then you have to add small amount of marine fish meal or plant based ingredients which are rich in that.
