The producers could see a new machine that allows the chopped forage grass silage such as corn, sorghum and sugarcane.
Over forty smallholder farmers north of Santa Fe, attended the talk “microsilos, an alternative to the small livestock producer” in the facilities of the Experimental Operating Tacuarendí in the General Department Obliged, north of the province of Santa Fe The event is part of the Meat Program Santafesinas and was in charge of the veterinarian Duilio L. Santana, Chief Operating Center Experimental Tacuarendí, and responsible for livestock. In addition, he was accompanied by animal nutritionist, Gustavo Dascanio.
During the day, the producers could see running a new machine developed by the company Omega SA of the town of Clover, allowing chopped forage grass silage such as corn, sorghum and sugar cane, the main crop used for animal feed in the region. This tool is proven technology for the first two crops and set stage for sugar cane, and is designed to meet the needs of small and medium producers.
On the other hand, technical Experimental Center, took the opportunity to conduct an experiment with chemical additives and biological conservation microsilos cane, from which positive results are expected for optimizing forage for cattle.
WORDS OF THE RESPONSIBLE
“When we work in the cane silage, one of the unintended consequences of this type of preservation, is the alcoholic fermentation, so in this paper, we have made experiments with different methods of preservation. In Brazil, for example, has been working hard on this type of conservation and have been developing methods to prevent alcoholic fermentation, producing lactic fermentation, which is desirable for this type of crop. They are working with chemical and biological additives. “Said Duilio Santana and continued:” What we intend, in this essay, is to replicate that experience and get good results with our materials. The experiment consists of samples in bags with these inoculants. Inoculants retain some chemical bags, on one hand, and other biological inoculants, and after 45-60 days of storage, we will open these microsilos and evaluate the outcome. What is new, including biological additives we are working, is that one of them is developing a regional company, “Nutreza” dedicated to animal nutrition, which adds value to the capabilities of enterprise technical innovation in the sector of area “.
“To have a good overview, we made three chemical treatments. One using sodium benzoate, another with quicklime, and the latter with urea. What we look for each of the treatments, is to stabilize the silo after opening. With respect to biological inoculants, be evaluated one that is already in the domestic market and one that is in face of experimentation, developed by the company named above. The latter includes different types and strains of lactobacilli and other microorganisms that promote conditions for fermentation processes are as required. In the process there is a stage aerobic conservation to be trying to go as fast as possible, then comes a stage of acetic acid fermentation in which there is much loss of nutrients, then there is a stage in which acid is produced lactic through interaction of the lactobacillus, and finally comes a stabilization stage in which the pH is lowered to acidic levels and in which there is practically possible developments of microorganisms. What commonly happens is that when you open the silo, resume aerobic processes that make the material should consume in a short time to avoid spoilage. We tried that with these additives that we are testing, we can stop this process and maintain the stability of the silo as many hours as possible, “concluded Santana.
Meanwhile, Gustavo Dascanio nutritionist, during the talk said: “What we want with this experiment is to control the fermentation process in silage cane. In this process, we need that the cultivation acid is made as soon as possible, and to generate a minimum amount of alcohol that can make better cattle fodder. To improve this process, we used different stabilizers. The novelty is that we are developing biological inoculant and uses several different types of lactobacillus and yeast strains. With this we hope that instead of generating an alcoholic fermentation is improved acid production, and in particular lactic acid is the most important. Moreover, we are convinced that with this additive, we will make better use of nutrients by the animal, which is critical to the success of this product, the producer who decides to apply “.
