Pedigree analysis in the Brazilian Zebu breeds

Journal of Animal Breeding and Genetics, 2009
SummaryZebu breeds play an important role in cattle production systems in Brazil. To assess the genetic variability from animals in the Herd Books of Nelore, Gir and Guzerat breeds, generation intervals, inbreeding, effective population size and parameters of gene origin (effective number of founders, ancestors and founder genomes) were calculated ...

Œstrus in Zebu Cattle in Uganda

Nature, 1955
DURING investigations into the possibility of artificial insemination of indigenous Zebu and Nganda cattle with homologous semen obtained by electrical stimulation, the œstrous cycles of an experimental group of heifers have been determined, using marked vasectomized bulls.

Studies on the habits of zebu cattle. III. Water consumption of Zebu cattle

The Journal of Agricultural Science, 1955
In continuation of a series of studies on the habits of Zebu cattle, records for the quantities of water consumed every hour by ten cattle during twenty periods of 24 hr. observations have been analysed.A large variation in day-to-day consumption was evident, but water was taken on an average during 8 hr.

Reproductive performance of Zebu compared with Charolais × Zebu females in a humid tropical environment

Animal Science, 1976
SUMMARYComponents of reproductive efficiency of Zebu-type and Charolais × Zebu-type (1/2, 3/4 and 7/8) females were compared. Zebus had longer mean intervals from calving to first service (57·8 days) and from calving to conception (46·0 days). Least squares means for both traits were respectively 129·8 and 145·1 days.

Efective Crossbreeding Systems Utilizing Zebu Cattle

Journal of Animal Science, 1980
The basic objectives and procedures for successful crossbreeding of beef cattle were considered, with special reference to the levels of realized hybrid vigor that might be anticipated for different crossbreeding programs involving the American Brahman (Z1) and European (Ej) breeds. Intralocus heterozygosis levels with respect to breed origin of genes (

Factors Influencing Gestation Length, Birth Weight and Calf Survival of Angus, Zebu and Zebu Cross Beef Cattle

Journal of Animal Science, 1980
Day of birth in a calendar year (DB), gestation length (GL), birth weight (BW) and survival rate of calves (SR) were recorded for 4 years for single-sire matings of (1) Angus (A) and Brahman (B) sires to A, B, Brangus (BR) and Africander-Angus (AF) dams; (2) BR sires to BR dams, and (3) AF sires to AF dams, a total of four straightbred and six ...

Relationship of serum guanase levels with economic characters in zebu purebred and temperate � zebu crossbred dairy cattle

Biochemical Genetics, 1981
Serum guanase levels of Indian Zebu (Hariana) cattle and its crosses with different exotic levels of temperate breeds of dairy cattle were estimated in 527 animals, and their associations with economic characters were determined. The overall mean value of serum guanase level was 13.46 +/- 0.45 IU/ml of serum.
