Reasons for Feeding Rabbits Salt and the Appropriate Amount to Add
Sodium: widely distributed throughout the rabbit's body, it maintains the balance of water, electrolytes and acid-base levels in the body, so that the rabbit will neither become "shrunken and dry" nor develop edema; sodium also regulates normal cardiac physiological activity, and to a certain extent promotes nerve conduction and gastrointestinal motility. Chlorine: mainly distributed in the extracellular fluid, it is the raw material for forming gastric acid and a component of gastric juice. Gastric acid can stimulate appetite, enhance digestion, and increase the digestion and absorption rate of protein and fat. If the rabbit's diet lacks salt, it will cause loss of appetite in the rabbit

What is the appropriate stocking density for raising pigs?
The stocking density of pigs refers to the pen area occupied by each pig, usually expressed as "sq m/pig". Stocking density indicates how densely the pigs are housed in the barn. Stocking density has a great influence on the air environment inside the barn. If too many pigs are housed, more heat is released, which helps keep the pig barn warm in winter but is unfavorable for heat protection and cooling in summer; it increases the levels of harmful gases, water vapor, dust and microorganisms in the barn, and also makes fighting among pigs frequent, affecting feed intake and rest. If too few pigs are housed, then

What is the most appropriate energy-to-protein ratio for fish feed?
Since the first requirement of fish in taking in nutrients is to meet their energy needs, from the perspective of fish nutrition, energy is the foundation of fish feed quality. The energy in feed is the sum of the energy contained in the three major nutrients in the feed - protein, fat, and carbohydrates. As a nutrient, protein is not only a major energy-supplying substance, but also has extremely important physiological functions, and these physiological functions cannot be replaced by fat and carbohydrates, and fish have a particularly high demand for protein, so protein is

The harm caused to pregnant sows by certain clinical drugs such as tetracycline, streptomycin, chloramphenicol, aspirin, nitrofuran drugs and antiallergic drugs is due to the use of intravenous injection when administering the medication, so that the drug reaches the fetus directly without passing through the liver. If changed to oral administration, it is relatively safe and effective. Therefore, when a pregnant sow falls ill, it is best to immediately ask a veterinarian to diagnose and prescribe medication.
