Bos Indicus was the cattle majorly used in Paraguay when Quebracho S.E.C.A Team have begun to manage "Estancia Quebracho". Even if the herd has completely changed today, we have always kept in mind that we had to conserve a bit of rusticity in our commercial herd.
November 2007 / December 2009 update see below
With this in mind and after years of Bos Indicus x Bos Taurus crossbreedings we are programming a small experience for the next months. We have bought few straws of 2 excellent Polled Nelore bulls for A.I. on our most "Bos Taurus" blood heifers, and will keep you posted!!! (update December 2009 see below)

The Nelore and the Brahman are of the species Bos indicus (Zebu), and have great dissimilarities to breeds of the Bos taurus (European) species.
Their most distinctive characteristic is the presence of a prominent "hump" behind their neck. The other characteristics of these cattle are their horns, which usually curve upward and are sometimes tilted to the rear, their ears, which are generally large and pendulous, and the throat latch and dewlap, which have a large amount of excess skin.
They also have more highly developed sweat glands than European cattle (Bos taurus) and so can perspire more freely. Bos indicus cattle produce an oily secretion from the sebaceous glands which has a distinctive odor and is reported to assist in repelling insects.
But there are many other fundamental differences between the Zebu cattle and the European breeds.
The strong points of the zebu breeds are:
Hardiness and rustling ability under conditions of poor range and drought
2.Heat and Insect Resistance.
The Nelore has a loose skin with sweat glands that are twice as big and 30% more numerous than those of the European breeds.
The Zebu's black skin, covered by a white or light gray coat helps filtering and reflecting harmful sun rays. Its low level of metabolism also contributes to heat resistance, as the Zebu feeds less but often, generating less internal heat.
Zebu possess natural resistance to various insects, as its skin has a dense texture, making it difficult for blood sucking insects to penetrate.
They also have a well developed subcutaneous muscle layer which enables them to remove insects simply by shaking their coat.
An essential trait we wanted to introduce in our Zebu herd when we have begun long time ago to look for crossbreeding was precocity. We have done that with several Bos Taurus breeds, the trophee being offered to the British White breed, with lot of heifers calving at 24 months years old.
Monumento TE de CV is a Polled Nelore bull recognized for it's precocity trait inside the Nelore breed.
Outono TE da Boticao belongs to a reknown lineage in Brazil, and its excellent pedigree has influenced our choice. The bull has been elected Grand champion and Grand Champion Reserve in four different exhibitions in Brazil during 2004.

3. Metabolic efficiency.
The Zebu can efficiently convert poor quality forages into beef, and withstand long periods without water. Due to their habit of feeding lightly but frequently, Nelore and Nelore hybrid cattle are highly resistant to bloating, and death losses rarely occur from this cause.
The Zebu cows calve very easily due to their greater frame, wide pelvic opening and larger birth canal, which reduces the incidence of distocia.
By A.I. a bunch of Nelore crossed calves are born, issue from crossbreeding with our Chargrey cows. The appearance is tipically Nelore, but with a superior weight at birth.
