An overview of Feeding Chickens for increasing Performance and Productivity

Overview of feeding chickens

An essential part of raising chickens is nourishing – feeding makes up the significant cost of production and great nutrition is reflected in the bird’s performance and its productivity.

Feeding Options

The most advantageous method for feeding chickens is with a well balanced pelleted ration, regardless of whether the birds are restricted inside or permitted to range outside. Most diets contain corn for vitality, soybean meal for protein, and vitamin and other mineral supplements. Commercial rations regularly contain antibiotics to promote and enhance development, coccidiostats for battling coccidiosis, and mold inhibitors. In any case, it is possible to acquire unmedicated encourage check nourish marks to check whether they contain feed additives. In the industry, feed is pelleted so the bird can eat more at one time. Chickens are nibblers and make visit to the nourish trough for little dinners, which requires vitality. Pelleting lessens the measure of vitality required for a feathered creature to bolster.  Distinctive rations are frequently utilized, depending upon the production stage of the bird. Starter rations are high in protein- an expensive feed ingredient. However, grower and finisher rations can be lower in protein since older birds require less. Access to clean water is important. Levels of total dissolved solids over 3000 ppm in the water can meddle with poultry wellbeing and production.

Home-mixed Rations

Poultry feed ingredients incorporate energy concentrates, for example, oats, corn, grain, wheat, sorghum, and milling by-products. Protein concentrates incorporate soybean meal and other oilseed meals, cottonseed meals, animal protein sources, grain legumes, for example, dry beans, peas, and alfalfa. Grains are generally ground to enhance absorbability. Since protein is one of the most expensive feed ingredients, the industry utilizes focused on rations and decrease the measure of protein in the eating routine as the chickens develop; notwithstanding, it may not be cost-effective to have diverse eating diets for starters, growers, and finishers. Vitamin pre-mix is normally included however might be diminished by utilizing horse feed. Different plants also give vitamins in their leaves, hulls, and wheats. Fish oil can give vitamins A and D. Yeast gives a ration of the B vitamins. UV light is a decent source of vitamin D for going chickens. Trace mineral is normally added to poultry diets, yet different sources can give minerals. Meat and bone meal is a fantastic source of minerals, especially calcium and phosphorus, and additionally being a decent protein source. Probiotics are once in a while given to chicks during placement and before transportation.

Certified Organic Diets

Home-mixed diets are especially valuable to certified natural poultry producers. In spite of the fact that pre-mixed natural poultry rations are accessible for procurement, they can be costly and maybe ought to be dispatched from long distances.

Feed Additives in the Diet

Feed additives are added to improve the efficiency of broiler growth, laying capacity of layers, prevent diseases and to promote health. The feed additives used in poultry diet include amino acids, vitamins, antimicrobials, pH control agent, and enzymes. Protein and amino acids form an important building block in poultry nutrition. The quality of protein is graded by its illeal amino acid digestibility, the higher the digestibility the better is the ingredient as a protein source. Deficiency of essential amino acids result in retarded growth or reduced egg size or reduced egg production.

To help the industry in balancing the protein turnover and amino-acid optimization of the birds, We at Vinayak Ingredients (India) Private Limited introduces one of our niche product with a brand name; KiFAY”- an Amino Acid Optimizer.  It is an all in one product for optimizing your poultry feed and production.

MOA OF KiFAY: It improves the availability of insulin receptors which are potential binding sites for IGF-1 and thus potentiating the action of IGF-1 resulting in improved  ileal digestibility of various amino acids in the feed and also improves the their uptake from blood. Thus improved amino acid accretion from blood results in better protein turn over. It also increases the efficacy and production of IGF-1 by stimulating insulin production resulting in increased bio-availability of IGF-1 in the liver.

The reason why we should use KiFAY:-

  • In broilers it increases the weight by improving feed conversion ratio (FCR) and protein utilization.
  • In layers KiFAY enhances the quality and other parameters of egg like;
  • Egg shell weight by 9-10%, Egg shell thickness by 15%, Egg weight 8%, Egg length by 15-16%, Egg width by 32-33%
  • It also reduces faecal nitrogen deposition by improving protein turnover.
  • It acts as a hepatoprotectant by inhibiting free radicals causing damage to the liver cells.
  • It  optimizes immunomodulation by enhancing Gut associated lymphoid tissues (GALT)

Thus KiFAY acts as a performance enhancer in poultry.

Maintaining protein nutrition in chickens

Necrotic enteritis in broiler chickens can be caused due to the increased
level of protein, 2-6 weeks post hatching. This is because of the over growth
of C. perfringens in the small digestive system, increasing from a typical
level of 10 4 CFU to 10 7 or 10 9 CFU per gram of digesta and causing harmful diseases.
With the increased dietary protein level, there will likewise be an increased activity of the trypsin in the small digestive system. This will, thusly, prompt to speedier arrival of coccidia from their oocytes which will lead so dynamic as to be less responsive to immunization.
In situations where such bacterial and protozoan are probably going to
prevail, it might then be advantageous, among different measures, to reduce the supply of protein and maintain it underneath the prescribed range. It is likewise important to consider the amino acid balance of the protein source to be utilized. Methionine and glycine, for instance, have been known to empower growth and establishment of C. perfringens and different pathogens in the gut.
Accordingly, the utilization of protein sources having over the top measures of these amino acids ought to be limited. Additionally, there are some protein sources, for example, cottonseed meal, raw soybean, and flax cakes, which contain varying measures of anti-nutritional factors, for example, trypsin inhibitors, gossypol, and glucosides. At the point when ingested by the bird, these components would then apply some damaging consequences for the small digestive tract, in this manner impeding
the safe mechanical assembly having nearby as well as systemic defensive capacities. Excessive utilization of such protein sources in the diet ought
to, therefore, be avoided as well.

NEONATAL POULTRY NUTRITION

Over the last five decades, improvements in nutrition and genetic selection have reduced the time required to produce a 2 Kg broiler within 1.7 FCR. The neonatal period is defined as the first seven days of the production cycle after hatch. It is a crucial time when the chick requires special management and nutrition. Efforts to control metabolic disorders such as ascites and leg problems have led to recommending early feed restriction during the first two weeks post-hatch. Thus, it is essential to know the effect of poultry management practices on subsequent chick development. A paper presented in the Ohio university explains the importance of the relationship of neonatal nutrition to muscle development. Muscle growth and development can be divided into two distinct periods: hyperplasia and hypertrophy. Hyperplasia is an embryonic period characterized by proliferation of muscle fiber number whereas hypertrophy is a post-hatch muscle growth that results in the enlargement of existing muscle fibers. Nutritional deprivation has a significant effect on myoblast cells. The research was conducted to evaluate the effects of an immediate post-hatch feed restriction on breast muscle formation. The increased number of nuclei in muscle fibers correlates with increased synthesis of protein and muscle fiber size enlargement. Myoblast cells are extremely responsive to the mitogenic effects of their environment, including nutrition. A 42-day length of a study conducted with feed restriction on the neonatal chickens showed a significant difference morphologically in the development and structure of the breast muscle between the feed restricted and unrestricted diet treatments. It also increased the deposition of fat in the breast muscle of the birds with the 20% feed restriction.
The Bottom Line Nutrient deprivation in the first few days after hatch may interfere with normal muscle protein development in broiler chicks. However, if you believe that flavor and juiciness follow the fat, there may
be some benefit from an early feed.

STEP TOWARDS “AMMONIA- FREE” ENVIRONMENT FOR POULTRY

Nitrogen is highly found in animal excreta and can exist in various forms. One such form is “Ammonia”. Primarily ammonia is a result of breakdown of urea present in urine of birds by the enzymes; urease and uricase. It is a potential source to create bad odor and negatively impact air and water quality and animal as well as human health. Presence of ammonia above 25ppm in the poultry house can damage the respiratory system of the birds and also there is a reduction in immune system; leading to declining flock health and performance. In addition to the effects on bird’s health, ammonia has significant hazardous effect on the caretakers and to the environmental ecology.

High levels of ammonia emission inside the poultry house have also become a cause of concern for the atmosphere outside the poultry house. Therefore there is a great need to develop strategies to reduce ammonia formation, volatilization, or downwind transmission of ammonia after it is volatilized from the poultry manure to minimize the harmful effects of ammonia on animal and human health as well as the environment.

Keeping this in mind and with a view to develop ‘ammonia- free ‘and organic environment for all, Vinayak Ingredients have launched a product with a brand name “KiFAY”. KiFAY is a blend of various herbal extracts in a diatomaceous carrier which acts as a DL-Methionine replacer and a nutritional feed additive and goes directly into the feed and acts as an amino acid optimizer and improves the apparent ileal digestibility of the feed and hence improves the protein turnover this also reduces the amount of amino acid degradation by the liver and excretion by kidney which form the major part of nitrogen compounds excreted by poultry. In turn these compounds are also responsible for ammonia and smell in the poultry house, apart from posing stressors for liver and kidney.

Vinayak Ingredients have also launched A Biosecurity product which combats the remaining ammonia emission in the droppings of the birds which acts as a litter amendment system under the brand name of “ESSENTIOLITT-POULTRY”. Essentiolitt poultry is an ammonia binder and has bactericidal action on urease and uricase enzymes and inhibit the ammonia formation by increasing 45% nitrogen retention and ammonia emission.

What is The Term Matrix Related to The Poultry Feed Industry?

Matrix is a term people will generally relate to the Keanu Reeves; even google will present you with this as a first page result. However matrix in the feed analogy is more related to something mathematical. The words digestible nutrients of feed ingredients and matrix are generally used as synonyms.  But matrix actually represents the nutrients available in the feed additive together with the nutrients spared or made available by use of the same additive in the feed formulation.  It represents the total nutrition provided to the animal body directly or indirectly by affecting the digestibility of feed. So, what is the use of matrix? We all remember our schooling days in mathematics and associate with a name called as Linear programming problems acronym as LPP. These are mathematical equations to link variables together to extract optimum results. One can set the key parameters such as price, dosage, availability, standards as variables with monetary profits as realistic outcomes. To give an example of LPP, let’s try this, for what combination of three machines A, B and C can work together with efficiency using each other’s limitations on different levels of time, use, power and accuracy to obtain an algorithm best suitable to manufacture maximum units of D in the least possible time, consuming least electricity and maintaining quality standards by reducing standard deviation. In layman terms it will give you a method of best utilization of available resources. So a matrix will enable us to use  LPP, which are now-a-days coded in software’s that help in formulating feed.

So how does one calculate the matrix of a feed additive? The answer is to run digestibility trials. These trials evaluate the nutritional availability from the ingredient to the animal. The availability can be further refined as in case of terms in energy as gross energy, metabolizable energy and so on. The digestibility trials also are needed to be refined on the basis of species, age, breed, sex and diet. A mature broiler breeder will have an ability to digest nutrients from corn which will be a different for a layer chick and a corn-soy diet with fishmeal will have different matrix then a corn-soy-bran diet with lupins. Once individual ingredient digestibility values are calculated the nutrional content can be corrected with these fractions to determine their true potential in feed formulations. Many phytogenic origin products have tried to replace certain high cost matrix products in the feed. But very few have succeeded to relate the plant sourced additive in terms of a compatible matrix value. The matrix can be also formed on the basis of growth studies where ingredient for ingredient replacement can be tested by using performance parameters. A correlation graph can be utilized to compare the new ingredients which fit better in an LPP for cost reduction with the old ones, falling short on the price front or other long term frontiers. In case of certain additives like phytase enzymes which result in mobilization phosphorus, the tibial ash content comparisons are also used to form matrix.

An in vivo digestibility assay in case of poultry ideally focuses of ileal sampling of digesta and deductively analyzing the same with oral fed feed. The birds are sacrificed and digesta is sampled at different levels of the gut to understand the digestibility of ingredients. As ileum is the terminal region of the small intestine and digestion is considered at its optimum here, the feed sampled in these zones is used for developing a matrix. The fecal collection is generally contaminated with renal excretions and is not considered as ideal to evaluate digestibility of precision fed feed. The most accurate theoretical method to estimate digestibility values is to use cecectomized roosters. Only few attempts to replicate the digestive values in vitro are successful and are not as accurate as in vivo methods. Most of the values tested in vitro were based on activity of enzymes on a certain feed grain and do not replicate real time complexities of in vivo trials.

Research is now moving to the molecular level, and ultimately it is the nutrients that are utilized at a cellular level that matter the most. Current digestibility studies focus on the nutrients absorbed from the intestinal lumen to the blood, whereas growth studies compare the net benefits from the additive. In the future our goal should be a point of intersection between these two studies with molecular markers used to light up our path to the least cost matrix for success.
