factors affecting egg size of poultry birds

As much as you want your chick to lay large sizes of eggs and you went and purchase the best breed. Also, you’ve gone through a lot of trouble to get them a good place to breed, you’ve invested in expensive equipment, to make sure they have the best facilities, you’ve gone into the neighborhood, including social media platforms seeking advise from experts and experience farmers on how to do effective rearing of the chicks to turn into layers, and the moment it was the proposed six months or probably five months and few weeks when your beloved chick are supposed to start laying, you discover the sizes of the eggs are really small.

This isn’t encouraging at all, and you ask your colleague in the business and they tell you that at the beginning, it is always so and that with time, the sizes will improve and you wait. But you realized that there haven’t been any changes since they started laying as promised by your friends, and this is affecting your marketing strategy, since consumers are more willing to pay for larger sizes of eggs, especially the vendors, supermarkets, market women and most especially those in the baking business, they will tell you they need bigger sizes for bigger business and you feel so down and discouraged thinking all hope is lost.

Well, today l am here to tell you that all hope isn’t lost as l am going to be taking you through the factors affecting egg size of poultry birds and what you need to carry out to have lager egg size and improve business. Stay with me

As you know, Egg size is so very important to poultry farmers because, the bigger the eggs, the higher the demand and monetary value. Though it is virtually impossible for all chickens to produce eggs of the same size, there are some factors that determine egg size. These factors include:

The way you breed your poultry laying birds determine their productivity and results. The environment you make them live in, the noise pollution around the area and other external factors will ultimately affect their egg size. Most breeders do develop strains which will produce egg sizes that is required by the market. You can carry out Random sampling test as it has been a reliable guide for comparing the sizes of different strains of layers in the market. You can now choose the one that works best for you.

  1. Feeds as one of the Factors Affecting Egg Size of Poultry Birds:

Like I said earlier, the feed you give to your birds can humans can affect the size of their eggs. Most rations in the market are well balanced but regrettably, some are not. However, if an unbalanced state of feed or badly mixed feed is administered or given, smaller eggs may result.

  1. Feed restriction as one of the Factors Affecting Egg Size of Poultry Birds:

Feed restriction mean depriving your birds of proper and adequate feed on time. If you want your birds to lay good and big eggs, all birds should be able to get a well-balanced food when they want it. Any restriction on feed, whether it may be due to lack of enough feeder space or forgetting to feed the birds on time or from using stale food, will definitely lower feed consumption and reduce your egg size.

  1. Lack of water as one of the Factors Affecting Egg Size of Poultry Birds:

When Water is too hot, too cold or dirty, it will be unpalatable to the birds. As a result, they will not drink enough. When this happen, food consumption will fall and egg sizes will suffer as they become not just small but tiny. Keeping the water fresh and clean will ultimately make them healthier and will increase the size of your eggs. Furthermore, look out for any faulty drinkers and or water suppliers.

  1. Protein level as one of the Factors Affecting Egg Size of Poultry Birds:

Rations are feeds given to animals. Rations that are containing less than 15 percent protein are liable to give smaller egg sizes. Although this is sometimes not likely to be a problem with commercially compounded rations, home mixers should keep a careful check on the protein point. By doing this, you ensure that your protein concentrate is included in the diet in an amount that will be up to 15 of the total.

  1. Laying-house temperature as one of the Factors Affecting Egg Size of Poultry Birds:

The temperature at which your laying birds are kept will affect the rate at which they grow and ultimately affect their egg size. Experiments conducted in several places and seasons have shown that 1 oz. per dozen less at temperatures over 70­­­­­oF than at 55oF. It is vitally important, therefore, to keep the house as cool as possible during hot weather. When the house is also too cold that the birds are seen clustering together, it is also not good as this can inhibit their ability to lay properly.

  1. Disease as one of the Factors Affecting Egg Size of Poultry Birds:

Most diseases will upset the birds, giving decreased feed consumption. This will only lead to lower production and egg size. Good hygiene and management will reduce this risk. When your birds are diseased, their entire functionality including egg laying is negatively affected.

  1. Age of maturity as one of the Factors Affecting Egg Size of Poultry Birds:

The age at which your birds mature will also affect the size of their egg. As it is said in Ibibio language of Nigeria: “ayen usong isi songho idem” which literally mean, “the child of your old age is not always physically strong”. Birds which mature early, such as those reared during increasing day-length, will lay a smaller egg than bird reared on a constant day-length or a decreasing day-length. egg serving size

Let’s take ourselves for example, if we use to carry 100 liters of water when we were 25, at 60, we should be carrying 45 liters as our strength has deceased. Birds at 20 to 26 weeks of age will lay smaller eggs than at 40 to 50 weeks. Maximum egg size can be expected when the birds reach about one year old. As the birds grow older, Egg size do tend to get smaller just before birds stop laying.

  1. Egg cooling and storage as one of the Factors Affecting Egg Size of Poultry Birds:

It is very important to cool eggs as quickly as possible after they are laid and to store them at a temperature of 50oF to 55oF, otherwise they will lose weight by evaporation and heat transfer. This may result in poorer grading results, and so a poorer economic return. When this happens, your return on investment will be too small if at all it will be there.
