How to identify sow lactation rate?
In the production, the sow’s lactation power can be identified based on the sow’s appetite, sensation, breasts, backfat, and its number of times and lactation times.
Specifically, the sows’ appetite during breast-feeding is relatively strong, and they can eat a lot of green and juicy feed or full-rate diets, and the daily intake is more than 6 kg. Higher power. Some sows do not have significant weight gain during pregnancy, and they do not lose their weight during lactation. Such sows do not usually have high lactation. Sows with high milking power had 28 to 32 milkings per day and night, and each time the milking time was more than 20 seconds. Sows with low milking power had less milking times and the milking time was short. If the sows’ breasts are full, the intervals are obvious, and the nipples are shiny and elastic, the piglets rarely “sucking teatsâ€. Such sows generally have high milk yield; if the piglets have “pig teats†phenomenon in the front and rear nipples, the common piglets have nipples in their mouths. Sleeping, or the piglets licking around from time to time to look for teats, indicates that the sow's lactation levels have begun to decrease; if the whole litter of piglets “pulls the teatâ€, it means that the sow has very little lactation. In terms of appearance, sows with thick shoulders, thick hips, and obese hips all have a low level of lactation, while sows with a single back ridge usually have a higher amount of milk.
How should I eat maize every day? We need to control the amount of corn, according to the dietary guidelines, the amount of staple food we use in our lives should be controlled at 250 grams to 400 grams, and the ratio of coarse to fine grains is one to three or one to four, which simply means that about 130 grams of corn can be used every day, in addition to the appropriate reduction in the intake of staple food, let's say half a bowl of rice or a steamed bun, so as to avoid excessive calorie intake in our bodies.
It is also important to note that when eating corn, it is advisable to eat the whole cob together to better control our blood sugar. If corn is processed into corn juice or cornmeal food, the nutrients inside are often lost and what remains is basically sugar, which is often higher on the glycemic index and more likely to lead to a rise in blood sugar, for example, the glycemic index of ordinary corn is only 55, but with foods such as cornmeal, the glycemic index often reaches 68, so it is important to eat the right corn.
