Embodiment 1

[0025] Example 1 Design and optimization of beef cattle fattening ration formula added with silage sorghum

[0026] 1. Experimental animals and experimental design

[0027] This experiment adopts single-factor experimental design, the concentrate is self-prepared biological concentrate, and the roughage is set up in five dietary treatment groups of A, B, C, D and E (Table 2).

[0030] 2. Feeding management

[0031] The experiment was carried out at the third breeding farm of Dingle Ecological Industry Group in Wuwei City, from May 1, 2016 to September 1, 2016, a total of 124 days, including 10 days of pre-feeding period and 114 days of formal experiment.

[0032] According to the principle of similar weight and age, 30 Simmental cattle were selected as test subjects (weight range: 350kg ± 25kg), and randomly divided into five test groups, with 6 heads in each group. Before the test, all the fattening cattle were dewormed. ...

[0105] 1. Experimental animals and experimental design

[0106] This experiment adopts a completely randomized experimental design. According to the principle of similar body weight and age, 24 Angus cattle are selected as test subjects (weight range: 350kg±25kg), and are randomly divided into four test groups, 6 in each group, A , Group B concentrates are self-prepared biological concentrates, and groups C and D are ordinary biological concentrates (Table 13).

Abstract

The invention provides a daily ration formula for beef cattle fattening with silage sorghum addition and application of the formula. According to the present invention, the ideal fattening effect of beef cattle can be achieved, the comprehensive utilization efficiency of sweet sorghum is improved, and the feeding cost is reduced, by scientifically allocating the daily ration formula with sweet sorghum in the cattle feeding process, scientifically screening premix and concentrate supplement, optimizing and obtaining the best scheme of the daily ration formula for beef cattle fattening, and formulating scientific and reasonable management regulations for cattle feeding with sweet sorghum at the same time. The daily ration formula of the invention is used to feed Simmental cattle, and the test results show that the group of 50% silage sorghum + 50 silage whole plant corn has the best daily weight gain and the highest efficiency of feed conversion, and the daily weight gain is 1.74 kg; andthe slaughter performance of 50% silage sorghum + 50 silage whole plant corn is higher, the slaughter rate is 57%, and the highest digestibility is 59.22%. The results indicate that the meat yield ofbeef cattle can be improved by replacing part of silage whole plant corn with silage sorghum.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to the formula of beef cattle fattening ration added with silage sorghum and its application. Background technique [0002] Since the reform and opening up, my country's beef cattle industry has made great progress and has become the third largest beef producer and consumer in the world. However, my country's beef cattle industry started relatively late, and the feeding methods are relatively traditional and extensive. The production level is far from that of developed countries in the world. The beef cattle industry is an important link in the virtuous cycle of my country's agricultural production system, and it is also an important industry that promotes the improvement of the meat consumption structure of urban and rural residents in my country. In beef cattle production, roughage plays an important role. During use, attention must be paid to the quality, processing...
