The relationship between age, weight and feed intake is a complex and delicate ecological balance, which is not a fixed value, but is influenced by a variety of factors. These factors include pig breed, feeding environment, feed quality, health status, etc., and changes in each factor can have a profound impact on the growth and eating habits of pigs.
First of all, the breed of the pig is an important factor that affects its growth rate and food intake. Different breeds of pigs have different genetic traits, such as growth rate, feed utilization, and disease resistance. Some high-yielding pig breeds, such as Landrace and Yorkshire, are genetically superior to faster weight gain and larger food intake under the same feeding conditions. Some local breeds or varieties with excellent meat quality, such as Jinhua pigs, black pigs, etc., although the growth rate is relatively slow, but they have unique advantages in feed utilization and meat quality.
Secondly, the feeding environment also has a significant impact on the growth and food intake of pigs. Suitable temperature, humidity, ventilation and light conditions can improve the appetite and digestion and absorption efficiency of pigs, thereby promoting their growth and development. Conversely, poor feeding conditions may lead to decreased appetite, indigestion and reduced immunity of pigs, which in turn affects their weight and feed intake.
In addition, feed quality is also a key factor affecting pig growth and food intake. High-quality feed contains sufficient protein, minerals, vitamins and energy to meet the nutritional needs of pigs and promote their growth and health. Low-quality feed can lead to undernutrition, slow growth and disease in pigs, which can affect their weight and food intake.
Finally, the health status of pigs is also an important factor that affects their growth and food intake. Healthy pigs have a good appetite and digestion and absorption, and are able to make full use of the nutrients in the feed, resulting in rapid weight gain and a stable food intake. Sick or sub-healthy pigs may have problems such as loss of appetite, indigestion and weight loss, which need to be diagnosed and ** in time.
Below is a rough reference table showing the average weight and feed intake of the pigs at different age stages. Please note, however, that this is only a rough guide and may vary in practice. In the actual feeding process, it should be adjusted according to the growth status of pigs and feed utilization, and the feeding intake of pigs should be weighed and observed regularly in order to adjust the feeding management plan in time.

Overall, the relationship between pig age, weight and feed intake is a dynamic process that requires comprehensive consideration and careful management from multiple perspectives. Only in this way can we ensure the healthy growth and efficient production of pigs, contributing to our food and economic development.
