Problems solved by technology

However, this method has the disadvantages of low nutritional content of oat hay and poor supplementary feeding effect
In addition, in relatively concentrated production cooperatives, fattening bases and other areas, most of the agricultural and sideline products are mixed and matched, steamed and other processes to make fattening feed for supplementary feeding of yaks, which can promote the growth of yaks in the cold season, but there is a waste of labor and the feed is not matched. Accuracy and other issues

Embodiment 1

[0023] A TMR diet and feeding method for improving the production performance of yaks in the cold season. The TMR diet consists of 120 parts of green hay, 100 parts of basic concentrate, 2 parts of premix, and 80 parts of water. The main raw materials of the basic concentrate are corn, wheat, highland barley, bran, bean dregs, calcium hydrogen phosphate, sodium hydrogen phosphate, rock powder, salt, etc. The guaranteed value of the component analysis of the concentrate nutrition is dry matter ≥ 86%. Protein ≥ 14%, crude fiber ≤ 8.8%, crude ash ≤ 7.0%, salt 0.3-0.9%, calcium 0.6-1.2%, phosphorus ≥ 0.6%. The main raw materials of the premix are feed vitamins, trace elements, amino acids, calcium, phosphorus, magnesium and NSP enzymes, etc., are packaged in a 2% dosage form, and are matched with feed at a ratio of 1:50. The green hay is the forage harvested in the same year, and it is stored in a dry and ventilated manner. It is forbidden to use expired moldy green hay to prepare...

Embodiment 2

[0027] Example 2 uses the feed component detection technology to compare the nutritional components of the TMR diet of the present invention and green hay, and the results are shown in Table 1.

[0028] Table 1

[0029]

[0030] It can be seen from Table 1 that the crude protein and crude fat content of the TMR ration prepared in this example is higher than that of green oat hay, while the indigestible fiber content is lower than that of green oat hay.

Embodiment 3

[0032] From December 15, 2014 to May 1, 2015, a 135-day fattening experiment was conducted in Guinan Modern Grass Industry Development Co., Ltd., Qinghai Province. The experiment was divided into three groups: TMR group; green hay group; traditional grazing group. To verify the beneficial effects of the present invention.

[0033] Table 2 shows the feed intake and breeding costs of the TMR group and the green hay group (the traditional grazing group is produced by free grazing in the cold season).

[0034] Table 2

[0035]

[0036] It can be seen that the average daily feed intake (DMI) of yaks in the TMR group was 5.19kg / head / d, and the fattening cost was 1205.1 yuan; the average daily feed intake (DMI) of yaks in the green hay group was 4.08kg / head / d, and the fattening cost was 754.6 yuan Yuan, in order to further illustrate the beneficial effect of the present invention, we have carried out the production performance index of cold-season yak and carried out statistics. ...

Abstract

The invention relates to the field of animal husbandry culture, and especially relates to a TMR daily ration for improving the productivity of yaks in cold seasons, and a feeding method thereof. The TMR daily ration comprises, by weight, 100-130 parts of green hay, 80-110 parts of a base concentrate, 2-4 parts of a premix and 60-90 parts of water. The TMR daily ration can reduce the grazing pressure of grasslands in the cold seasons, reduces the energy consumption of yaks in the grazing activity process in the cold seasons, alleviates the grazing weight loss, and improves the calamity resistance; and the TMR daily ration has the advantages of balanced nutrition, good palatability, increase of the food intake and the forage grass resource utilization rate, maintenance of the stable state of rumen microbes, reduction of the disease incidence, promotion of growth of the yaks, substantial improvement of the total weight gain, the mean daily weight gain and the culture benefits of the yaks in the cold seasons, and yield and benefit increase. The TMR daily ration is in favor of realizing precise and large-scale yak culture.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a TMR diet and a feeding method for improving the production performance of yaks in cold seasons. Background technique [0002] Livestock production is the main economic base of the Qinghai-Tibet Plateau, especially yak breeding is the main source of income for herdsmen in alpine pastoral areas. In recent years, the stock of livestock in pastoral areas has continued to expand. Due to the traditional grazing production model, yak breeding is overly dependent on natural pastures, and the pastures are overloaded and overgrazing, resulting in serious degradation of pastures, decline in grassland productivity, and a sharp drop in forage production and quality. As a result, the production efficiency of yaks is low, and the breeding income is poor. [0003] Due to the destruction of grassland ecological environment and low economic returns caused by this traditional grazing mode. Herds...
