Saving feed in the farm, improving feed conversion efficiency, and reducing the feed to meat ratio can directly improve the benefits. EYn China Feed Industry Information Network - based on feed, serving animal husbandry

Use the excellent variety EYn China Feed Industry Information Network - based on feed, serving animal husbandry

Different varieties of pigs have great differences in feed conversion rate and daily gain. Changbai pig, about gram pig, Pietrain, Duroc and other lean meat varieties or ternary and quaternary pigs are in reasonable feed nutrition. Under the condition, the growth rate is fast, the daily gain is high, the feed compensation is high, and the feed-to-meat ratio is low, while the local breed pigs have a slow growth rate, a low daily gain, and a high feed-to-meat ratio. Therefore, when selecting seeds, you should first select the variety with high feed compensation. EYn China Feed Industry Information Network - based on feed, serving animal husbandry

Balanced feed nutrition EYn China Feed Industry Information Network - based on feed, serving animal husbandry

The formulation of nutritional standards generally considers the best weight gain and low feed ratio. Every day a pig grows, it consumes a portion of the feed to maintain its life needs. The growth and development of pigs is related to feed intake and feed quality. If the protein and energy levels of the feed are low, the pigs will increase their feed intake and eat more. Relatively speaking, the larger the feed intake, the faster the pig grows, but the excessive feed intake will definitely affect digestion and absorption, thus increasing the feed-to-meat ratio, so the pigs may not have a quick feed reward. Under the same conditions, the feed is fed with high-nutrient feed, and the feed is lower than the feed with low nutrient levels. Therefore, the feed formula should strive to balance nutrition and maximize feed compensation. EYn China Feed Industry Information Network - based on feed, serving animal husbandry

Improve the health of the herd EYn China Feed Industry Information Network - based on feed, service animal husbandry

Chronic respiratory diseases, sputum, skin diseases, parasitic diseases, acute violent morbidity, etc. will affect the conversion and absorption of feed to varying degrees, the growth rate is slower, and the ratio of feed to meat is increased. Therefore, it is necessary to increase the health of the herd, and use the whole group of health care once a month with Yinqiaosan (1 kg of 1 kg of mix). Regular deworming, in the 3rd, 6th, 9th, and 12th of each year, use Weiyuan Jinyiwei (2kg of mixing material 1ton) to purify the sow herd parasite for 7 days, and the commercial pigs are 20kg~30kg and 100kg. At ~120 kg body weight, they were continuously dewormed for 7 days. The mycoplasma is purified regularly, and the mycoplasma is continuously purified for 15 days in March, June and September using Miao Lisu (150 g of 1 ton mixture).

Environmental control EYn China feed industry information network - based on feed, service animal husbandry

1. Feeding density. According to the practice data, the higher the stocking density of the pigs, the lower the daily weight gain and the higher the meat-to-meat ratio. EYn China Feed Industry Information Network - based on feed, serving animal husbandry

2. Temperature. At around 25 °C, pigs need the least amount of maintenance, and most of the energy consumed is used for growth, so the feed conversion rate is the best at this time; when the temperature is 35 °C, the intake is reduced, and the energy intake is not enough to maintain its needs. , causing growth stagnation; when the temperature is below 15 °C, energy is needed to keep out the cold, otherwise the meat ratio is worse.

Raising management level to improve EYn China Feed Industry Information Network - based on feed, serving animal husbandry

1. Feeding method. The scientific feeding method has free feeding and regular quantitative feeding. Generally, the reasonable feeding time is lower than that of the free feeding. The feeding amount per meal is controlled within two hours after feeding. EYn China Feed Industry Information Network - based on feed, serving animal husbandry

2. According to the size, strength and weakness of pigs, reasonably group, avoid bullying, bullying and uneven growth, timely isolation and care of sick pigs, reduce residual pigs and reduce the loss of feed, reduce the ratio of feed to meat.

3. Reasonable daily operation. Minimize the impact of various stress factors on the herd during the feeding process. EYn China Feed Industry Information Network - based on feed, serving animal husbandry

Feeding age should be appropriate EYn China Feed Industry Information Network - based on feed, serving animal husbandry

The experiment showed that the fattening pigs grew fast before 60 kg, and the lean meat grew slower after 60 kg, but the fat deposition accelerated and the fat ratio increased. The nutrients needed for fattening pigs to grow 1 kilogram of fat are equivalent to the nutritional needs of 2.6 kilograms of lean meat. Therefore, when the pigs are raised too much and are too fat, not only the lean meat rate is low, the fat is high, the materials are consumed, and they grow. Slow, high meat ratio, affecting the economic benefits of raising pigs. EYn China Feed Industry Information Network - based on feed, serving animal husbandry
