The role of grass in pig production

Providing adequate, high-quality litter (usually straw) to the pig during different growth stages of the pig can play a role in the welfare of the pig because it can provide a comfortable environment for the pig, and it acts as isolation, entertainment and provision. The role of nutrition.

The litter not only provided farmers with more convenience, reduced the breeding cost, but also allowed the pig to enjoy its due welfare. On the one hand, supplying straw mats will reduce the adaptation of pigs to lower critical temperatures because litters can reduce body heat transfer to the ground. Especially at a lower temperature, the pig body can be kept warm and comfortable. However, under warm weather conditions, the litter strengthens the heat stress reaction. If the straw gets wet and dirty, the isolation effect will be poor, therefore, When using litter, pay attention to the ventilation of the pig house. On the other hand, thick straw bedding makes the surface of the floor the same as a mat, not only makes the pig's body more comfortable, but also reduces the occurrence of swine legs and foot rot disease. Many studies have reported that weaned pigs and growing pigs have less chance of developing hoof disease and bursitis on thick straw than on slatted floors.

Straw mats in the pig house can provide nutrients and crude fiber to pigs, so that pigs are full of appetite, so it will make more sense to limit feeding. Straw is a kind of pig feed, which itself is rich in nutrients such as crude fiber, crude protein, crude fat, etc. Because rice straw is a material left over from rice harvesting, it used its own photosynthesis to make it. Many nutritional plants. Therefore, straw is a highly nutritious substance. So how do we know how much fat and crude fiber the straw contains? We can use the crude fat analyzer or the crude fiber analyzer to measure the crude fat. The former is used to measure crude fat, and the latter is a crude fiber analyzer. It is designed to measure crude fiber. The instrument looks a bit similar, and it can measure many substances at the same time.
