Generally, the reasons for the decrease in fattening pig feed intake are as follows:
1. Palatability factors of feed
, Dry and wet issues There are currently three types of feed materials for pigs, namely dry powder feed, wet mix (water feed:) and dilute feed. According to experiments, wet feed feeding method has the best feed intake, while thin feed feeding method has the worst.
. The corn particle size required for crushing is .~mm. The palatability of the too fine material will be reduced, thus affecting the feed intake.
If the crude fiber content in the feed is greater than the crude fiber content level, the feed intake of pigs will decrease.
, Salt content Normal growth and fattening pigs’ demand for salt is . When the salt content drops to .
Sweetener: What pigs like most is sweetness. If the feed contains sweetener, the feed intake will increase.
2. Changes in feed odor will also affect pigs’ feeding
Changes in flavoring agents, such as the conversion between frankincense type, fishy type, fishy type, and sweet type, or the time of exposure to the air If it is too long, the smell will evaporate and become lighter, which will affect its feeding.
. Feed moldy deterioration. If the feed is contaminated by mold, the feed becomes moldy and produces a musty smell, which will reduce the feed intake of pigs in terms of odor and palatability.
Feed rancidity If the ambient temperature is high or the feed is stored for a long time, the crude fat in the feed will oxidize and become rancid, causing a havoc smell, which will reduce feed intake.
Different types of oils, such as soybean oil, corn oil, etc., are added to the feed, and the smell will be different. If it changes, it will affect the feed intake.
The special smell of other raw materials affects the feed, such as the fish meal content and quality, etc.
3. Certain feed ingredients directly affect the physiological response of pigs, causing their feed intake to decrease
In terms of amino acids, the feed intake of pigs increases with the increase in the lysine level in the feed, but to a certain There is a downward trend in feed intake after a certain period of time.
In terms of minerals, the lack of zinc and phosphorus in the feed and the excess of calcium, manganese and iron will all cause poor appetite of pigs.
In terms of vitamins, deficiencies of b, b, b, niacin and pantothenic acid will all reduce piglet feed intake.
A large number of tests on antibiotics have proven that adding a small amount of antibiotics to pig diets can increase pig feed intake.
In terms of water, in the early stage of water shortage, pigs' appetite will obviously decrease, especially they do not like to eat dry powder. As water loss increases, the pig's appetite may be completely eliminated.
In terms of energy, feeds with high energized content will have low feed intake, whereas low energized feeds will result in high feed intake.
In addition, some pig diseases such as parasitic diseases, colds, gastroenteritis, etc., changes in the temperature of the pig house, and the process of group transfer, merging, feeding, and epidemic prevention in the process of raising pigs will all affect the pigs' food intake. In addition, we should pay attention to increasing the feed intake of pigs. Only when they eat more can they grow faster. On the premise of avoiding the above situations, you can add some additives, such as meat and poultry life elements. According to experiments, in the feed The addition of meat, livestock and poultry life elements can effectively increase feed intake by ~3, improve feed conversion rate, increase daily weight gain by ~3, shorten the feeding cycle, and at the same time enhance disease resistance.
