WHAT IS MEANT BY CBI?
It is a mixed farming system implemented in areas of good agricultural potential, where cattle breeding is done with an intensified management in all its aspects (animal health, nutrition, genetics, etc.). Food is basically based consociated pasture grazing on alfalfa. The grazing management (forage allowance and pasture breaks) becomes paramount, ensuring the fodder needed to keep many heads per hectare (5 cows / ha) during the life of the pasture. This load is kept nursing-service (spring-summer), and during the dry period (autumn-winter) the cow graze the stubble.
To withstand high loads in this system must be implanted pastures on fertile soils thus enabling good forage production. Considering the two activities (agriculture and livestock) are most benefited both these alfalfa consociated with temperate grasses, because they provide a more balanced forage chemical composition for cows, reducing the risk of filling and forage production ( by excessive moisture or drought). Furthermore, in the rotation of the field, this pastoral cycle and fertility adds organic matter to the soil chemistry to the following agricultural period. The vast complementation is achieved in this system, is that during the time of lower nutrient requirements of cows (dry cow) are available crop residues or residues that are an excellent resource for this category.
The system thus proposed CBI the alternative of bovine calf agricultural soils, complementing both. Just as the application of new technologies in these soils to maximize crop production crop, this technical proposal aims to allow express the productive potential of breeding herds in areas of the core area. Unlike the proposals classics, is located at the breeding cow production in top condition, maximizing stocking and calf production per hectare, at low cost. Central objective of achieving mixed production sustainable and economically sustainable over time.
Fields ranchers traditionally called, ravines, low or some limitation to grain production should continue breeding livestock, as the most viable alternative and sustainable production for these situations. However, in the areas of greatest agricultural potential within the crop rotation in agriculture-are continually raises again the benefits of including cycles not only to improve pastures and soil conditions but to exercise better control over certain pests, even in those cases or conservation tillage.
The technical proposal is that within livestock options that make good use of these perennial pastures, breeding is regarded with more intensive management (yet have low fields or ravines). This will give an opportunity to the cow-breeding the best golf get very good production and economic results. As it includes the whole system, it is considered that the animal droppings and roots of pasture conditions improve soil physical and chemical properties (structure and nitrogen). Turn provide free agricultural crops crop residues (stubble) to cows, who take advantage of this resource effectively producing meat, saving in this system the use of herbicides to control winter weeds or “chemical fallow.”
The premise is that during basic nursing and service when the cow has the highest nutritional requirements have highly productive pastures (15 to 20 tons / year of dry matter) and optimum forage quality, covering those needs even with a stocking of 5 cows / ha. Later, during her infancy, during the dry period when significantly lower in nutritional needs, in a rational graze the stubble of corn and soybeans.
For optimal management of breeding herds with high loads per hectare, is fundamental proper grazing management, ensuring the necessary fodder for cows in full lactation with the additional need for energy to power their reproductive activity during service. It is therefore important rest time required for recovery pasture, that to achieve this is very important knowledge and practical application of the proper use and management of electrified wires or threads. The proper use of this technology allows not only the allocation of forage needed and rest of the pasture (grazing system), to be able to modify the size of the plots according to supply fodder for every moment and situation of the pasture during the year, and the production cycle of pasture and cow. This system of livestock farming, to succeed in their results must produce more, and as in other activities must innovate, reduce costs and make better use of available resources, mainly through better management of process technologies. In short, if you can maintain and improve cost efficiency.
Therefore, the focus of the work is to promote cattle breeding activity, improving their productivity and competitiveness by reinforcing their management seeking higher yields per hectare to raise the profitability, sustainability and sustainability of the agricultural system- overall livestock.
Within the general objectives for intensification of breeding activity arising:
- Increase efficiency (economic and biological effectiveness) of cattle breeding by stocking increases, procreos increases, raising the rate of weaning per cow per hectare.
- To improve the level of knowledge of farmers through training and technology transfer, articulating running programs (for example, “Carnes Santafesinas 2000” MAGIC).
- Generate and develop new technologies in the breeding process, with the participation of INTA Experiment Stations and Universities (Faculties of Veterinary and Agricultural Sciences). Improve income level of the rural population and all activity related sectors.
- To strengthen the roots and permanence of the rural population in the field.
- Improve the living standards of livestock producers.
SIMULATOR – CBI / INTENSIVE CATTLE BREEDING. VERSION 1.0
The CBI Simulator is a user-friendly software designed for professionals and livestock producers developed by INTA Venado Tuerto, to simulate different levels of forage production by field, although, according to the amount of forage selected stocking-modify. This is possible to achieve a better balance between seasonal forage deficit with strategic supplementation required by the rodeo with different resources, calculating also the results of physical and economic production, to be able to update the prices of inputs and outputs in the system considered.
In the first screen is the presentation of the program, in addition to the title which has a button to the authority of the same, also has access to load on the second screen.
In this second screen are the Producer Information, which charged the full name of the producer, the name of the establishment and pasture area in hectares.
The third screen is for the technical data, contains several “ears” where you can change the input supply, production rates: replacement of sows (%), pregnancy (%), shooting (%), calf mortality, of the rearing and adults (%), entore (%), marketing expenses, purchase and sale (%), livestock staff salary and consulting fees ($), pasture life (in years), agricultural yields of corn (kg / ha) to calculate the surface yields of corn stover as.
Then on the fourth screen, the screen enters Prices, where you can update the prices of inputs used in the activity: food, forage, pasture establishment, veterinary and farm prices by category. This upgrade price is in pesos (white boxes), is also expressed in dollars. Update the value of the dollar or $ s.
In the fifth screen accesses the composition of the cost of implementing the pasture, that data can not be changed (you can only change the price on the screen).
In the sixth screen accessible to the composition of the cost of herd health, considering it used in cows, bulls and calves. There are no plans at this time of the health program modification (a change can only occur in the display of prices).
Subsequently, various options are accessed (4 screens) Supplementation, where you select the resource to use to correct nutritional deficit autumn-winter pastures to handle high loads, thus able to maintain high production levels. The resources considered are: corn grain, pasture, hay, corn silage and corn stover.
For each simulator acts supplementation, for it must be selected by field forage production per hectare (kg DM / ha), and must also simulated a stocking rate (cows / ha). For each resource has a table where there are two management alternatives that consider the type of replacement sows with heifers brand liquid (ML) and purchase of cows (CART) analysis for both situations is the same. All analyzes are per hectare of pasture and the total area of pasture establishment. First analyze technical data load of cows and heifers (heads), and the amount of supplement (corn, hay or silage) necessary, as well as the amount of meat (kg) sold. Below, we analyze economic data, or revenues from sales of calves / as, cows and bulls rejection. To analyze expenditures or expenses supplementation, health, replacement cows and bulls, pastures and staff. Thus leading to gross margin achieved for each situation, expressed in pesos and in dollars per hectare and total area. There is also a potential that expressed Surplus Forage rolls / ha or $ / ha.
There are also graphs for each supplementation which simulates the annual projection of the pasture, or supply energy (Mcal / ha pp) expressed green bars, and supplementation needs expressed in a curve which represents the kg of maize / cow / day for each month that need to be added, depending on load and forage production. So are plotted supplementation options (hay, corn and silage), the only change necessary kg and the cost of each, being different Rastrojos option is plotted as area and expressed the acres of stubble needed per ha of pasture, This option has no cost (value applicable rates).
The last two displays, one hand have a bar chart which summarizes the eight alternatives described above, or ML and Replenishment Replenishment Purchase, with four alternative supplementation (corn, hay, silage and straw) for each. The graph shows negative values (red) for each expenditure, and positive values (green) gross margins achieved in each case. In turn, have production buttons animal feed and load that can simulate the variation of the eight alternatives simultaneously, in graphical form. On the last screen, you get the detailed values for each case of how one comes to the physical (kg / ha) and gross margin ($ / ha) plus the cost per kg of meat produced for each case ($ / kg).
In short, this program can analyze gross margins of different alternatives of supplementation can vary all prices of products and inputs, as well as technical data production. Simulating also different loads and different green fodder per hectare, thus obtaining the impact on the physical-economic outcome for each modification of their values.
