Directions of Growth, Improvement and Prospects for Efficiency of the Productivity of Sheep Breeds Tigaie in the Context of Zootechnical Bioeconomy

Abstract

Nowadays, tigaie breed represents almost 26 percents of tha total sheep group in our country, being grown on the hill, plateau and depression areas, with atmosphero=ic precipitation of 650-800 mm, and in limited number in some submontane areas. The proportion of the Tigaie breed will be in the future of about 24% of the total herd. Due to its exceptional resistance and superior combining capabilities, the Tigaie breed will be a biological source of industrial cross-breeding and improvement, as well as the creation of new types, for fine-meat-milk wool, such as Spanca genetically stabilized or semifine-wool, as well as semi-wool milk. In order the breed to be properly harvested in the shown directions, it is necessary to keep valuable cores in the pure breed, subject to an appropriate selection and propagation program. The economic efficiency of animal production is largely determined by the results obtained by forage crops, the low cost of feed, contributing to the increase in the economic efficiency of livestock production.

New Approach for Bio-Economic Integrated Management in Sheep Growth

Abstract

A rising of sheep flocks represents one of the economical procedure imposed to be solved every one year, in the generations’ succession, through a judicious organizing of a complex reproduction activity, of breeding, of exploiting, of improvement and economical analyzing. A consequence of unspecified disease of this specie is the morbidity and the losses, generated by the infringement breeding exploiting conditions, adding the parasitical diseases, especially these linked to the lawns. This work suggests to be a radiography of the actions connected to breeding and exploiting the sheep on family farm conditions. The scientific management of production process is supposed to know the results of the activiyies of the assembly factors, which influence in a positive or a negative way the economic efficiency level, regarding the irrational leading of all the actions made to obtain a maximum economic efficiency.

Study on the Setting Up of a Horse Tread on the Ialomita River

Abstract

In Romania, the living environment of salmonids is the mountainous and pre-mountainous waters, the alpine lakes and the reservoirs built on mountain rivers. Improving living conditions of salmonids involves work on stabilizing mountain water courses, regulating their flow, reducing the transport of alluviums. Salmoniculture includes concerns about artificial growth and amelioration of Salmonidae populations in special resorts called trout. The researches were carried out at SC Cascada Laur SRL Moroeni, a specialized breeding farm. Having a land with very poor agricultural potential, but conducive to the development of an aquaculture activity, on the Ialomita River, in 2007, the company decided to build a farm for the breeding and breeding of trout. The technical documentation has been carried out and the infrastructure of this economic unit has begun.The pond basins have a wooden trunk shape with dimensions of: 4.00 x 20m - 3 pools; 3.25 x 9.70m - 4 pools; 12.80mx 2 m - 1 pool and a pool of 12.00 x 6.00m. The main features of the buildings: - Soil basin (trowel), trout for breeding and fattening of the trout, waste water basin, incubation micro station, filter. Economic growth of salmonids: a viable alternative to protecting the natural resources of the planet; an important source of animal protein, easily digestible; have a determining role in maintaining human health; efficient valorization of feed; obtaining constant productions throughout the year; low crop areas, high growth densities, exploitation from the piscicultural point of mountain accumulation lakes and impassable land for agriculture; reduced expenses with the staff employed; meeting the demanding tastes of consumers.

Analysis of the Active Principles of Different Cannabis Varities

Abstract

Cannabis cultivated as the main raw material for textiles is another than the one used for its psychotropic effects. From a botanical point of view, however, plants are virtually imperceptible.

What is changing is the concentration level of the active principle, depending on the type of cannabis. Cannabis Indica has a higher amount of resin and a higher cannabidiol percentage than the Sativa variety.

The hemp cultivated for fibers and especially Cannabis sativa L, which includes the types grown in Romania and generally in Europe, have a low content of narcotic and hallucinogenic substances (0.2-0.3%). This hemp is specially formulated and used for the production of fibrer.The hempcultivated for drug is not grown in. Romania. Because there are no processing plants factories, all the production in Romania is sold for export. Subsidies are given for the cultivation of these varietes. The benefits are great because textiles obtained from hemp are superior to those from countries like China and Germany. The hempcultivated for drug is not grown in Romania.
