Chickens, as one of the common poultry in humans, have always been the focus of attention of farmers and animal nutritionists. In daily feed, corn is often used in chicken diets as a major source of energy**. However, a careful observer may find that chickens do not always peck at the whole corn kernel directly, and there are many factors involved, including the physical characteristics of the corn itself, as well as the feeding habits and physiological state of the chickens.
First of all, corn size is one of the key factors that affect whether chickens directly peck at whole corn. In its natural state, corn kernels vary in size, and oversized corn kernels can cause swallowing difficulties for chickens, especially for chicks whose digestive systems are not yet fully developed. Therefore, in order to ensure that chickens can ingest and effectively use the nutrients in corn, modern farming industry usually pre-treats the corn in the feed, such as crushing or flakes, to make the corn kernels easy to eat and digest.
Secondly, chickens have a clear feed preference. They tend to choose foods that are easy to peck at and have a good taste. In a mixture, if there are smaller pellets or foods that are more appealing to the chickens, the chickens may prefer these more accessible foods and set aside the larger whole corn for the time being.
In addition, the digestive characteristics of the chicken to the whole corn are also very important. Although chickens possess powerful gastroliths, the gizzards (also known as muscular stomachs), which can digest whole grains of corn, their digestion mechanism is not simple. In the natural environment, chickens often eat by pecking on the ground while ingesting grit, which is mixed with food and ground inside the gizzard to help digest crude fiber and hard-shell grains in food, such as whole corn. Therefore, it is very necessary to provide chickens with the right amount of grit under captive conditions, which helps to improve the efficiency of chickens in digesting whole corn and further optimize feed utilization.
In addition, it should not be ignored that chickens tend to have a reduced appetite and feeding ability during certain diseases or specific physiological stages, such as moulting, which indirectly affects the intake of whole corn. During this time, chickens may be more inclined to opt for small, easy-to-digest pellets and less feed intake for whole corn.
In summary, under normal circumstances, as long as the corn is the right size, and the feed mix is reasonable and the necessary grit is provided, the chicken is fully capable of eating and effectively digesting the whole corn. Understanding and respecting the feeding behavior and digestive characteristics of chickens can not only better meet the nutritional needs of chickens, but also further improve the breeding efficiency and achieve scientific and refined feeding management.
