Summer shade net in the end pig helpful?

In order to explore ways summer pig high yield and efficiency, a veterinary tested cover the stadium sty Sunshade Net participants 206 Yorkshire pigs selected from the group consisting of Swine hybrid 37 feeding randomly divided into two groups, the first a group of 107, is covered with a Shade Net ground (abbreviated coverage group), a second group 99, network coverage without shading (control group). The pigs in both groups were healthy, disease-free, normal development, and the difference in age and body weight was not significant. The pre-feeding period is 7 days. During the pre-feeding period, the epidemic prevention, castration and deworming work were carried out in a unified manner, and fed in the test period. The formula is as follows: corn 47%, bean cake 15%, bran 15%, rice bran 16%, fish meal 2%, yeast powder 2%, bone meal 2%, additive 0.5%, lysine 0.5%. 20 grams of multivitamin per 100 kg of feed. The feeding method is wet and mixed, and it is fed 3 times a day, so that the amount of food is not enough. Free drinking water, pig pens are regularly disinfected to keep the pigsty trough clean and quiet. The measurement data is recorded on a regular basis and is settled on a regular basis.

The test results show that the summer coverage of shading nets has the following advantages:

First, the pigsty is hygienic. There is no mosquito flies in the covered pigs, and there are few pig diseases.

Second, the daily gain is high. The average daily weight gain of the pigs in the covered group was 650.08 g, which was 29.26 g higher than the 502.92 g of the control group.

Third, the unit weight gain and consumption is small. The covered group consumed 3.41 kg of feed per kilogram of weight gain, which was 16.72% lower than the 3.98 kg of the control group.

Fourth, the economic benefits are good. According to the compound feed price of 3.66 yuan/kg in the test period and the purchase price of fat pig 14.52 yuan/kg, the feed fee for each kilogram of weight gain: 8.32 yuan for the covering group, 1.24 yuan for the 9.56 yuan for the control group; The coverage group was 443.23 yuan, which was 120.01 yuan higher than the control group's 323.22 yuan. The test results also show that it is best to cover the shading nets for feeding pigs at 6, 7 and 8 months per year, and it is better to raise about 10 heads per lap.

Based on the above experimental results, we can see the importance of raising pigs in the summer.
