Buvanendran, V.[Fertility in zebu cattle: Breeding performance of Malawi Zebu cattle kept under traditional systems of management (part 1) and causes of sub-fertility (part 2)]Fertility in zebu cattle: Breeding performance of Malawi Zebu cattle kept under traditional systems of management (part 1) and causes of sub-fertility (part 2)

The study was carried out to investigate the milk yield potential of Bunaji and Sokoto Gudali breeds, the environmental factors influencing dairy traits and to estimate the genetic parameters of some of the economic dairy traits. The data were 2177 records from 545 Bunaji cows and 928 records fro...

Body measurements have been used to predict live weights of cattle, an important variable in determining market value of an animal. Animals of varying ages from White Fulani (Bunaji), Sokoto Gudali and the N'Dama breeds of cattle were evaluated to determine the relationships between weights and ...

The performance of Bunaji and Bokoloji cattle under same management for three years were investigated. Lactation and reproductive data of 888 calvings from both breeds were analysed. Milk yield was significantly different between the breeds. Lactation lengths were also significantly different. Mi...

An analysis of reproductive data on White Fulani (Bunaji) Zebu cattl of Northern Nigeria was carried out. The season and year of birth had no effect on age at first calving (P>0.1). The mean age at first calving was 40.4± 0.7 months. The distribution of heifers, classified according to age at fir...


Oyedipe, E.O.Buvanendran, V.Eduvie, L.O.[Some factors affecting the reproductive performance of White Fulani (Bunaji) cattle]Some factors affecting the reproductive performance of White Fulani (Bunaji) cattle

Some of the genetic and environmental factors influencing performance traits of indigenous beef calves and their crosses in Nigeria are examined. The Bunaji and Sokoto Gudali, and Charolais x Bunaji crossbreds were evaluated for calf weights at 3, 6 and 12 months of age. Environmental and genetic...


Oni, O.O.Buvanendran, V.Dim, N.I.[The influence of some environmental factors on growth rate of two Nigerian cattle breeds and their hybrid with the Charolais]The influence of some environmental factors on growth rate of two Nigerian cattle breeds and their hybrid with the Charolais

Comparative evaluation of the zebu and crossbreds to heat tolerance were carried out over a period of 4 months. Physiological measurements of two indigenous zebu breeds of cattle, Bunaji (BU) and Sokoto Gudali (SG) and the half-crosses of Friesian-White Fulani (CB) were taken after exposure to fi...


Buvanendran, V.Adamu, A.M.Abubakar, B.Y.[Heat tolerance of Zebu and Friesian-Zebu crosses in the Guinea savanna zone of Nigeria]Heat tolerance of Zebu and Friesian-Zebu crosses in the Guinea savanna zone of Nigeria

Knowledge of the extent of variation due to non-genetic factors is vital to eliminate environmental effects and improve the efficiency of selection in sheep. Two indigenous breeds, the Udah and the Yankasa and crosses of these with exotic breeds were evaluated for lamb weights at birth, 3 months ...

Haemoglobin variants were studied in a population of 104 Red Sokoto goats of over 1 year of age and in 49 kids. Three haemoglobin variants and 5 phenotypes were detected. The observed proportions of haemoglobin phenotypes in animals over 1 year of age differed from the expected numbers calculated...

A study was conducted in Nigeria on 30 Bunaji and 30 Sokoto Gudali cattle to select for growth rate on the basis of chest girth measurements during the commencement of the fattening period 4 weeks and 6 weeks after fattening. The predicted mean weights of the two breeds of cattle coefficients of ...
