Protein is the foundation of all life and constitutes the main component of pigs. When there is a lack of protein in the diet, the sows will have abnormal sex cycles, are not likely to become pregnant, have fewer litters, have miscarriage, have weak babies, stillbirths, and geeks, affect milk yield and milk quality; boars will have libido Decreased spermatozoa and sperm count, p, decreased semen quality, and loss of ability to bred; piglets show slow growth or stagnation, reduced resistance, edema, and eventually death. Therefore, it is very important to supply the necessary protein during the pig production process. Puyang Linshi Medical Supplies Co., Ltd. , https://www.linshihealths.com
So, is it better for protein feeds to feed pigs? From an economic point of view, all feeds containing more protein (such as bean cakes, bone meal, blood meal, fish meal, etc.) are generally of higher prices, and feeding more will increase the cost of feeding and cause waste. From the physiological point of view, feeding too much protein feed will increase the burden of liver decomposition (deamination), endanger the normal excretory function of the kidney, and even cause ammonia poisoning in pigs. Therefore, too little or too much protein in the pig diet has an adverse effect. We must supply the right amount of protein according to the pig's growth stage and production level.
In general, the younger the pig, the more protein is required to weigh per unit; on the contrary, the older the pig, the less protein is needed per unit of body weight, which is the general nutrient law that pigs need for protein. We should master this law and apply it to the practice of raising pigs to obtain the highest economic benefits with the lowest breeding cost. To this end, the amount of protein needed by pigs at each stage of age and category is described below:
Suckling piglets (5-10 kg), protein feeds accounted for 22%-26% of dry matter; dry weaned piglets (10-20 kg), protein feeds accounted for 20%-22% of dietary dry matter; Xiaokurong pigs ( 20-35 kilograms), protein feeds account for 18%-20% of dietary dry matter; Da Khan pigs (35-60 kilograms), protein feeds account for 16%-18% of dietary dry matter; fattening pigs (60-100 Kilograms), protein feeds account for 12%-15% of dry matter for diets; boars (for breeding), protein feeds account for 15%-16% of dry matter for diets; sows (empty), protein feed accounts for the day 12%-14% of dry matter; sows (pregnant), protein feed 13%-15% of diet dry matter; sows (lactating), protein feed 14% of diet dry matter-16 %.
