IDIOMA
LOCATION
The company runs its forestry and cattle far-
ming operations in the department of Esquina
in the southwest of the province of Corrientes.
This is 70% located on provincial road 30 and
the rest on provincial road 59. Production ex-
tends over 35,000 hectares, of which 32,000
are owned and 3,000 are leased.
CLIMATE
The climate of the region is warm temperate. The
warmest month is December with average
temperatures of 27 C (80.6 F), average highs of 31
C (87.8 F) and average lows of 22 C (71.6 F). The
coldest month is July with average temperatures
of 14 C (57.2 F), average highs of 19 C (66.2 F) and
average lows of 9 C (48.2 F).
Our rainfall records for more than 50 years show
a historical average of 1270 mm with maximums
of 2080 mm and minimums of 670 mm (year
2022).
SOIL
The Chavarría series (Typic Psammaquent) soils occupy the largest surface area of the fields.
They are mostly sandy, gently undulating, and with low fertility levels, little organic matter and P
values ranging from 0.5 to 1 ppm.
Water runoff is slow to medium, permeability is moderately slow and drainage is imperfect to
moderate due to a subsurface layer of clay that also generates a false ground water table near
the surface.
This ground water table gives rise to numerous circular lagoons that fill this environment.
These soils are suitable for livestock and forestry.
FORAGE RESOURCES AND LANDSCAPE FEATURES
In Esquina, Corrientes, cattle farming is carried out on sandy, gently rolling plains, with short
grass and permanent lagoons, and low fields formed by scrublands and marshes along streams
and rivers which flood during part of the year.
Our forage resources are mainly natural fields with good quality grasses on sandy, gently rolling
plains, and medium quality grasses on low wetland fields. There are short grass species with
good forage quality such as Paspalum notatum and Sporobolus indicus, and long grasses such
as Paja colorada (Andropogon laterils) of low forage quality, Paja amarilla (Sorghastrum
setosum) and Paja mansa (Paspalum quadrifarium).
There is good diversity of leguminous plants of small size and low volume that complement the
good quality grasses.
Receptivity in high altitude fields is 0.65 EV/ha and in low altitude fields it is 0.4 EV/ha.
In high altitude fields, there are nearly 3,000 hectares of winter pastures (pure Setaria narok or
Brachiaria brizantha and Brachiaria humidicola) with a receptivity of 0.85 EV/ha.
PRODUCTION MODULES
The livestock farm is made up of 5 independent production modules:
· La Victoria
· Libertad
· San Vicente
· Capibara Cué
· Santa Bárbara.
The livestock team is formed by 49 people led by a production manager agronomist (Livestock
and Forestry) and two work areas each with a livestock manager, an agronomist and an
agricultural production technician, a Jr. veterinarian, an administrative officer, 5 foremen, 25
farmhands (“peones”) and caretakers (“puesteros”), and 14 structure personnel.
We have a consulting team in Genetics (DVM Diego Grané), in Health and Breeding (DVM
Alejandro Brusca and DVM Mario Acosta), in Tick Control and Management (DVM Marcelo
Lavalle), and in Nutrition (Agronomists Dario Colombatto and Felipe Pereyra Yraola). Agr. Jorge
Esquivel is our comprehensive consultant.
FORESTRY IS DIVIDED INTO 5 OPERATIONAL AREAS:
· Vivero,
· Administración,
· Silvicultura
· Caminos
· Cosecha
We have a comprehensive consulting team
led by Agr. Jorge Esquivel, and a consultant in Nursery (
Omar Lopez) and in FSC Standards (Mario Ochoa).
PRODUCTION SYSTEM
Cattle raising is a complete cycle starting with
breeding, rebreeding of males and females, cow
wintering and breeding herd.
It is an extensive or semi-extensive activity carried out
on natural fields, pastures and winter annual grasses.
In these fields, livestock and forestry operations are
integrated in silvopastoral systems.
It is in high altitude fields, with sandy, gently rolling
plains suitable for forestry and good development of summer pastures and winter annual
grasses, where these two activities are combined.
Livestock activity is complemented with forestry in silvopastoral systems with a low tree density
planting system and a planting design of 2.5 m x 4 m paired rows and 12 m wide alleys, which
results in a symbiosis between both activities. In this setting animals enjoy the benefit of shade in
summer, and pastures do not freeze in winter and do not dry out as quickly in summer because
of shade and lower evapotranspiration. And animals keep the volume of pasture low, reducing
the risk of fire, the main problem of forestation.
In the 12 m wide alleys, pastures and winter annual grasses are grown.
HERD MANAGEMENT (BREEDING)
We have a breeding herd of 9,000 heads, 50% of which are Brangus (85% black Brangus and 15%
red Brangus) and the other 50% Braford.
Service is 75% in the spring, from October 1 to December 30. The remaining 25% is an early service
in autumn to 1st service heifers. This is for 18-month-old replacement heifers and takes place from
February 10 to April 10. In both cases, the service dates follow the natural curves of grass produc-
tion, the main resource used in this production system.
Historical pregnancies in spring services are around 85-87%. In order to achieve these values, we
must rely on lactation management, giving a differential treatment to cows with calves, depen-
ding on their reproductive status. An anestrus test is performed 60 days after calving and three
results are obtained: Cycling, where cows continue service with their calves at foot; Shallow
anestrus, where the calves born to these cows are weaned temporarily (“canned”) for 15 days. Fi-
nally, cows that are in Deep anestrus have their calves weaned when they are 60 days old and
weigh 70-80 kg (early weaning). This tool helps to maintain constant levels of reproductive indi-
cators.
In both spring and autumn services, artificial insemination techniques are implemented to incor-
porate genetics, accompanied by natural mating. Insemination is used for dry cow herds in the
breeding herd and in the general herd, while fixed-time insemination (FTAI) is used for cattle in
the breeding herd with calves at foot.
Spring service calving occurs in July, August and September with a late calving in October. Early
service calving occurs in November and December.
During calving, calves are identified with different colored ear tags (renewed every two weeks),
in order to ensure good lactation management.
Conventional spring service weaning takes place at the end of February and beginning of March
at a weight of 180-190 kg. The weaning of the first calf of the fall service is in May at a weight of
140-150 kg.
The herd is divided into General Herd and Breeding Herd, where the general herd is distributed in
4 of the 5 modules and the breeding herd is in the fifth module (La Victoria).
There are 7,500 and 1,500 dams in the general herd and breeding herd, respectively.
40% of female calves are rebred for dam replacement, 30% are rebred for commercial service
and future sale of pregnant heifers, and the remaining 30% is destined for fattening and finishing
in the feedlot, and then sale to slaughterhouses.
5% of males are destined for replacement of bulls for subsequent replacement of parent bulls,
and for sale as breeding stock. The remaining 95% is destined for steers and finishing in feedlot.
REBREEDING OF FEMALES AND MALES
FOR REPLACEMENT OF DAMS AND SIRES
The rebreeding of females for replacement is basically carried out in a pasture system, starting at
weaning in autumn on summer pastures, for three months, with weight gains of 0.350
kg/head/day and 30 kg in autumn. Then at the beginning of winter they pass on to winter
pastures with 210 kg on June 1 until October 30 with 290 kg, with weight gains of 0.650
kg/head/day; and then back to summer pastures until reaching 330 kg in February, the weight
necessary to get the heifers pregnant at 18 months of age.
REBREEDING OF STEERS
Castrated males are rebred on summer pastures and winter annual grasses, a forage chain
similar to that of replacement animals. This category reaches 300 kg in the autumn following
weaning and is transferred to feedlots outside the farm for fattening for export.
