Chicken 4 important principles

After take-off on hatch day, day-old chicks are stored for a period of time before being moved to the farm. Chick storage time can vary considerably, from just a couple of hours to an overnight stay. A sound understanding of the principles involved in storing chicks is vital to preserve chick quality and performance and ensure the well-being of the chicks. This article explains these principles and highlights good chick holding conditions.

1. Logical unloading of the hatcher avoids overheating

The hatcher itself is a very good holding environment for chicks as it is designed to have a very tightly controlled and stable environment with a lot of cooling and a forced airflow. But of course, chicks cannot stay in the hatcher forever as they need to be separated from the eggshells and any unhatched eggs.

The moment you pull the trolleys from the hatcher, the airflow surrounding the day-old chicks will be reduced to whichever airflow you have in the area you move them into. Therefore, it is essential you avoid pulling all trolleys from the machine at once because this can lead to overheating of the chicks and subsequent dehydration. When pulling the trolleys from the hatcher, the best thing to do is pull in such an order that the last trolley in the machine is always the one closest to the temperature probe, to avoid overheating of the remaining baskets.

2. Maintaining an appropriate ambient temperature is vital

After separation from eggshells and further processing, you will have to store the day-old chicks in the chick storage room for a period of time.

Hatchlings are unable to regulate their body temperature in the first weeks of their life. They rely on the ambient temperature to stay in perfect shape.

During storage, the internal temperature of the birds should remain between 39.5C and 40C (103F and 104F). When the bird is at this temperature, it will breathe through the nostrils limiting the amount of moisture loss to around 2 grams per 24 hours. At this rate, birds can be held very comfortably for extended periods of time.

The ideal chick storage room temperature varies, depending on the air speed. Generally speaking, 24°C-26C (75°F-79°F) with a constant airflow and supply of oxygen-rich air results in comfortable chicks. Lower temperatures require slower air speeds and higher temperatures require higher air speeds.

Vent temperatures give a very accurate reading of a bird’s temperature, but are invasive, time-consuming and only inform you of the conditions in the area you are monitoring at the time of measurement (conditions can change very quickly). Therefore, the behaviour of the birds is a far better and proactive indicator of their comfort levels.

Up until today, the Romijn and Lokhorst observation (as shown in the table below) is by far the easiest, quickest and most effective way to determine chick comfort.

Aquatic Feed Mill. The Best Choice for Shrimp Farming

Shrimps have balanced nutrition, soft meat, and are easy to digest, so they are beneficial to asthenic. The high content of magnesium can regulate the cardiac activity, protect cardiovascular system, prevent hypertension, and myocardial infarction. Rich phosphorus and calcium are good for children and pregnant women. So shrimp products get more and more popularity. This causes the rapid development of intensive shrimp farming. Feed pellet costs of shrimps account for a large proportion of shrimp farming. So shrimp breeders seek top quality feeds.

About Aquatic Feed Pellets

Aquatic feed pellets are produced based on the shrimps’ features and nutrition needs, mix raw materials evenly according to a certain proportion, then form the final pellets through an aquatic fish feed pellet machine. Aquatic feed pellets are especially made according to shrimps’ physiological character so they are the best choice for shrimp farming.

Aquatic Feed Pellets Benefits

1. Good water durability

Shrimps are slow eaters. Their habit of slowly nibbling feeds needs aquatic feed pellets to keep the shape in water for a long time. Aquatic feed pellets have a smooth surface and hard texture so they can maintain the shape in the water.

2. Balanced nutrition

Aquatic feed pellets are made based on the nutrition needs of shrimps and adopt scientific formula so they have good palatability and balanced nutrition. This can ensure shrimps are not picky about feed, feed pellets are easy to digest absorb and have a high utilization rate.

3. Improve water quality

Now feed accumulation is the main factor causing water contamination. The frequent feeding is easy to cause feed residue and feed accumulation. Shrimps should be fed two to five times each day. If shrimps are fed by feed pellets which have good water durability, then pellets feed will not decay before shrimps eat them. And the feed pellets quantity is easy to control so as not to cause feed accumulation and pollute the water quality.
