Studies on the habits of zebu cattle. III. Water consumption of Zebu cattle
The Journal of Agricultural Science, 1955In 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.

Mother–Offspring Interactions in Zebu Cattle
Reproduction in Domestic Animals, 2008ContentsThe knowledge of the interaction between mother and offspring might contribute to enhance the welfare of the offspring and to improve the reproductive efficiency of the cow. However, there is still little information available about such interaction in some cattle breeds.

Observations on the ovaries of zebu cattle in Northern Nigeria
Research in Veterinary Science, 1978A morphological study was carried out on ovaries of 236 local zebu cattle. Ovaries from 189 of the cattle were found to be abnormal grossly. Histological observations indicated changes due to old age. The findings are discussed in relation to the occurrence of low reproductive efficiency in cattle in Northern Nigeria.

Response of Nigerian zebu cattle to Zeranol implants
Tropical Animal Health and Production, 1980The effect of Zeranol, an anabolic agent, on the weight gains of Nigerian zebu fattening bulls was investigated over a period of 16 weeks. Implanted Sokoto Gudali and White Fulani bulls showed average daily weight gains of 0.5 and 0.49 kg respectively as compared to 0.47 and 0.41 kg by non-implanted counterparts.

Antigen and protein polymorphism in Somali zebu cattle*
Animal Blood Groups and Biochemical Genetics, 1980SummaryBlood samples, collected from 143 Boran and 34 Dawara adult cattle, belonging to a state farm in Mogadiscio, have been tested for red cell antigens with 40 cattle reagents and for Hb, CA, Tf, Alb and Ami types.Gene frequencies are presented and the results indicate that the two breeds are very similar in all the systems studied.

Preweaning Growth Rate and Weaning Traits of Angus, Zebu and Zebu-Cross Cattle
Journal of Animal Science, 1982A 4-yr study was conducted on the preweaning growth rate and weaning traits of 620 calves from: (1) Angus (A), Brahman (B), Brangus (BR) and Africander-Angus (AF) dams sired by A and B bulls; (2) BR dams mated to BR sires and (3) AF dams mated to AF sires. Heifers were placed in the breeding pastures as 2-yr-olds and exposed to bulls for 75 d.

Puberty in South American Bos indicus (Zebu) cattle
Animal Reproduction Science, 2004Puberty in Zebu heifers follows a pattern characterized by a decrease in the steroid feedback mechanism and an increase in LH concentration, which result in the first ovulation followed by a short estrous cycle and the onset of normal cycles thereafter. These events are similar to those observed in Bos taurus cattle but occur at a later age.
