Switch cows and crops, to achieve high yields of animals per hectare and improve soil sustainability: a proposal for farmers Pampa INTA with livestock concerns are voiced.
Deer Eye Research INTA-Santa Fe, showed that by integrating agricultural production and livestock grazing, managed to increase the stocking rate per hectare, for meat quality, improve physical and chemical properties of soil and soybean yields multiply and corn. This intensive cattle breeding (CBI), ie, include cows in the corn-soybean kernel, an interesting example of biological and economic efficiency.
“The challenge is to express the productive potential of breeding herds purely agricultural environments,” said Martin Correa Luna, a regional reference in this subject and organizer of the III International Review of Livestock to the Pampas, to be held on 28 and August 29 in the city of Santa Fe-Firmat. Next to the INTA, the provincial Ministry of Production and the Faculty of Veterinary Science (UNR) are at the forefront of this third edition of the conference, which convened more than 500 livestock producers and agricultural science professionals.
“The premise is simple,” said Correa Luna and explains: “For the stubble left by corn and soybeans are added alfalfa-based pastures. This keeps a load of five cows per hectare during spring-summer and a head of thick crop stubble in autumn-winter. “
Thus, in the best environments is achieved mixed and sustainable production by maximizing stocking rate, the increase in the production of calves per cow and per hectare at low cost and soil conservation management in high-yield agriculture, detailed Correa Luna.
With the base in the rotation, the scheme includes agriculture production by 80% and pastures for cattle by 20%. In this sense, it is important to manage sites with electric fencing to manage grazing area assigned and respect the moments of rest.

Grazing, forage allocation and rest periods for pasture are essential to ensure high loads: up to six animals per hectare with an average of 20,000 tons of dry matter per year. “With management practices results in increased productivity and biodiversity is preserved,” said INTA specialist.
“The breeding cows are harvesting dry matter transform it into containers called beef calves,” said Raul blua, joint owner of the establishment “Casco” Chañar Ladeado-South of Santa Fe. “As a producer,” added, “looking to add kilos of meat and, for this is important to manage the breeding of a professional and spend lots and good grass.”
According to the producer, this includes health management, nutrition and genetics. “We know that the diet of the cows should be balanced over the cycle, so it is necessary to cover the winter forage deficit,” he added.
In your school, blua managed to increase yields in corn and soybeans, plus you get to six animals per hectare: “This scheme provides stability to the system in dry years, maintaining production and profitability, as well as lower production risks “.
INTA trials determined that it is possible to increase the load during the winter with an early sowing oats on half of the surface in soybean: “This increases the nutritional value of forage availability,” said Correa Luna, to whom should be used crop stubble, “Let the cows eat the ears that are lost, husks, cobs, leaves and crop residues of soybean. It is an option to supplement the diet during the winter period. “
This activity requires attention throughout the year, demand for rural labor and can increase jobs and rooting in the field. For this coach Venado Tuerto INTA referred to this paradigm as “living areas”, because they live and work throughout the year at the establishments.
