The economy of every country relies on the participation of different economic activities. The size and development of the various economic activities make them vary in size and participation to contribute to the national economy (national cake). In developing countries, the livestock sector does have a share in contributing to GDP ( gross domestic product) compared with other economic sectors. This sector in Tanzania is more significant in size and development than other East African countries; thus, its contribution to the economy (GDP) is uncertain in conjuction with other available alternative existing energies. This paper investigates the livestock sector's contribution to the economy with other African countries and relates to other economic activities. It maintains that such a comparison not only increases the performance of the livestock sector but also strengthens its relationship with other economic activities in order to increase its economic contribution. Our study shows that improved relations and linkages between the livestock sector and other economic sectors are essential to improving the performance of the sectors, investments, and, ultimately, improving its contribution to the economy. Based on the research and data collected from livestock sectors, the coefficient of correlation was made to relate to other economic activities to see their cooperation and determine the potential actions to be used innovatively.

The livestock sector plays a significant role in rural, urban, and developing countries. There is an increasing demand for livestock products in developing countries, due to the growing numbers of the population. The livestock sector offers employment opportunities, food nutrition, bioenergy, and mode of conveyance in different parts of the country. In this article, we evaluated the sustainability of the livestock sector using various business strategy plans. As a result, the livestock value chain is time-consuming and complicated, with no linkages. It recommends clear marketing strategies, strength, and support various sources of finance. The establishment of different cost centres and various participants and stakeholders set the direction of the livestock value chain to make it sustainable. The level of demand and supply, resource allocation help all agents to increase their profits, reduce the cost of circulating capital, improving logistics, supply, and efficient time utilization. All participants have to take precautions about the emergence of changing technological structures in all issues of copyright, patents, and differences of cultures. They need competent, skilled people who are willing and truthful in all operating functions. Most significantly, all efforts to sustain the livestock sector sustainability require a cooperative and efficient management team. This team will be responsible for taking into account all the responsibilities to the fullest. They will be responsible for the day to day operations of the livestock sector.

The livestock sector is among the significant sectors in poverty mitigation in Tanzania National Strategy for Growth and Reduction of Poverty. Livestock offers employment opportunities, source of food nutrition, energy and mode of conveyance in various parts of the country. Moreover, domestic animals like cows, goat, sheep, poultry, and pigs are the means of getting money for consumption. There is an increase in demand for livestock products resulting from the increase of population size around the world. This paper will contribute to the increase in investment in the Livestock sector to transform the economy to an industrialized economy by using livestock resources. The role of cooperation was used to evaluate how Tanzania and China cooperation develop sectors of the economy. The findings showed that there was no development made in the investment in the livestock sector through this cooperation to transform the current state of industries. The lower level of technology through ought the livestock value chain draw back the development of industries in Tanzania economy. The suggestion made from the study is that the efforts made to develop other sectors of the economy like infrastructures in main roads, office buildings, institutions framework can be used through this cooperation to develop the industrial sector to transform the current state of the economy to an industrialized economy.
