Tropical breeds

Product benefits

In South America, CRV also has a breeding program for tropical breeds. Under the tabs below you can find more information about the different breeds.

One of the tropical breeds of CRV is Girolando, a crossbred between Gir and Holstein. Due to its cross, Girolando, is a very fertile and efficient breed with a good milk production that is able to produce in a sustainable way in the tropical and subtropical regions. CRV is selecting 4-8 Girolando bulls per year.

The Girolando breed has a good reputation in Brazil. 80% of the milk production is coming from Girolando cows. They are able to keep a good level of production in different management systems and climate conditions. Girolando was bred with the aim to create a breed that is able to produce in a sustainable way in the tropical and subtropical regions. It is grounded on crossbreeding the Holstein breed (HOL) with Gir (GL), starting with a ¼ HOL + ¾ GL cross until they ended with a 7/8 HOL + 1/8 GL cross. Because they wanted to breed a productive breed that meets the needs of dairy farmers, they finally ended up with a 5/8 HOL + 3/8 GL cross: the Girolando.

History: Gir is a Zebu breed, originally from India, regions of Gir in Kathiawar Peninsula. Along the races of Mysore, in the south, and the races of the mountainous regions to the north, it is considered the oldest creation. The first Gir animals probably should have been introduced in Brazil around 1906. The genealogical record of the animals is carried out by Associação Brasileira dos Criadores de Zebu (ABCZ) based in Uberaba / MG.

Dairy selection: In the 30’s, some breeders, identified in different herds Gir animals which stood out for its dairy capacity. Gir is the result of the selection made by government and by private breeders in São Paulo, Minas Gerais and Rio de Janeiro states, who based their work with emphasis on milk selection. It was formed a specialized biotype, with measured production to distinguish the animals for performance and knowledge of the production level of its lineage, since great-grandparents, grandparents, mother, father, brothers and daughters. The merit of these creators is equivalent to those who held the historic Zebu imports from India to Brazil. These are breeders and experimental stations that believed and potentiated this ability to produce milk, as a natural race since its inception.

Features: Gir stands out for its rusticity, productive and reproductive longevity, docility, low cost of maintenance, calving ease, milk production on pasture (has excellent feed conversion) and versatility at intersections. Gir reduces costs of food, medicine, veterinary care and labor required for feeding and caring for the animals of the herd.

Crossings: When crossed with Holandês, Gir produces Girolando an extremely rustic animal, with exceptional food conversion and high milk production. It can also be used in Jersey cows to produce Girsey and Pardo Suíço will result in Giropar and with both races for the production of rustic crossbred and high yield.

Genetic improvement: Among the factors that based the genetic evolution of the race, is Programa Nacional de Melhoramento Genético do Gir Leiteiro (PNMGL), created in 1985. It is a work performed by the Associação Brasileira dos Criadores de Gir Leiteiro (ABCGIL –headquartered in Uberaba / MG) with Embrapa Gado de Leite. The main objectives of the program are to promote the improvement of the breed through the identification and selection of genetically superior bulls for production traits (milk, fat, protein and total solids), conformation and management, as well as the genetic evaluation of animals of all participating herds.

Dairy control: This is one of the tests carried out by the Programa de Melhoramento Genético de Zebuínos (PMGZ) from Associação Brasileira dos Criadores de Zebu (ABCZ), allowing to identify the herd matrices that develop in milk production during lactation. Data from milk control are also crucial for the formulation of the Bulls Summary prepared by ABCZ with Universidade Estadual de São Paulo (UNESP – Jaboticabal/SP).

The history of Kankrej or Guzerá, is lost in the origin of mankind, having been found printed stamps on ceramic and terracotta in the archaeological sites of Mohenjo-Daro and Harappa, India and Pakistan, and its image in several parts in the regions of ancient Assyria and Mesopotamia. Guzerá habitat is the pre desert region kutch in Gujarat, followed in the north by Thar Desert and Sind desert. In Brazil, Guzerá is spread through several regions but is notorious its presence in the northeastern region, where it was the only race that survived, productively during the five consecutive years of drought (1978-1983), and has also faced other historical droughts (1945, 1952 etc.).

The dairy female Guzerá has, on average, a beautiful udder. Ligaments are strong and consists of a thin, silky skin that, when milked, seems a deflated bag. In fact, Guzerá udder shrinks and almost disappears, as if the female had produced nothing. A good example seems to be the cow “Surprise-JA” which, after traveling more than 3,000 kilometers, seemed that had no milk at the competition. Many suggested not include the cow to avoid discredit the race but the creator was exhaustive and included the cow that produced 16.0 kg and won the competition, even thin and tired.

Guzerá Dairy bull is used as a zebu alternative at intersections. From the early history of Zebu in Brazil there was interbreeding between Guzerá and other existing dairy breeds, especially Holandês, creating “Guzolando”.

Reliable breeding values are the basis for sustainable breeding.
