“…Navel height was measured as the distance from the ground to the lowest point of the cow's belly bottom (navel). Body length was measured from the hindmost part of the animal to the valley in front of the second thoracic vertebrae just ahead of the centre of the shoulders (Alphonsus et al, 2012). Body depth, chest circumference, body length and flank circumference were measured using a plastic tape measure.…”

“…White Fulani cattle are, however, considered important for their genetic predisposition of hardiness, heat tolerance and adaptation to local conditions (Alphonsus et al, 2012). The White Fulani is a triple-purpose animal, with milk production of 2,300 kg per lactation.…”

The precarious supply of animal products to Nigerian populace may worsen if livestock production is still based on the use of multipurpose indigenous cattle breeds with genetically low productive potentials. The main objective of this study was to determine the reproductive performance of Zebu cattle in an AI program in The Federal Polytechnic Mubi, Livestock Farm, Adamawa State, NorthEastern Nigeria. Twenty (20) female Zebu cattle comprising heifers and cows were selected at random from the cattle herds, February to March, 2016. The insemination was performed via recto-vaginal technique following estrus synchronization, using prostaglandin F2α (PGF2α). The results of the study showed animal age ranging from three (3) to ten (10) years old with parity from 0 to 5. The body condition scores of the animals vary from 2.0 to 2.5 indicating poor nutrition and management practices at the period. There was 100% estrus detection rate since all animals displayed signs of heat and were turned in for insemination. The findings showed a low success rate of 25% with higher failure rate of 75%. It was concluded that, Ayrshire and Brahman crossed Zebu female cattle through AI, though gave low fertility rates at the first attempt, is still the rapid means of improving milk production and reproductive efficiency of the combined adaptability and hardiness of the Zebu cattle (Bos indicus) with the genetically high reproductive and milk yield potentials of the exotic breeds (Bos taurus). There is still room for an in-depth future study of the effects of upgrading indigenous Zebu cattle crossed with exotic bulls to maximize production. This is important in realizing the goal of increasing the production and reproductive efficiency of the indigenous crossbred cattle in the country. This would also ensure sustainable food security in the NorthEast and Nigeria as a whole.

“…According to Pagot (1992) and Babayemi et al (2014), the most prominent autochthonous breeds of cattle in Nigeria include White Fulani (WF), Sokoto Gudali (SG), Adamawa Gudali (AG), Red Bororo (RB), Ambala (AM), Wadara (WA), Azawak (AZ), Muturu (MU), Keteku (KE), N'Dama (ND) and Kuri (KU). The WF Fulani cattle breed also known as Bunaji is the most widely spread local breed and most numerous comprising 37% of all cattle (Meghen et al, 1999;NNLRS, 1999;Alphonsus et al, 2012). Furthermore, they are valued for their genetic predisposition of hardiness and are superior to other breeds in terms of diseases resistance, heat tolerance, ability to thrive under varying thermal environment and adaptation to other local conditions (Blench et al, 1998;Alphonsus et al, 2012).…”

Regarding phenotypic characteristics of WF, the hump is large and well developed, navel flap is small, horns are of medium length, up curving and lyre shaped.…”

Heat Shock Protein (HSP) 90 gene is a member of HSPs subfamily that act as molecular chaperons whenever animals come under thermal stress. The genes fulfill essential roles of providing cellular protection, immune response, protein synthesis, protein folding and unfolding, protection from cellular stress, inhibitory apoptosis and adaptation. This study was designed to analyze polymorphisms of HSP 90 and to evaluate their influence on heat tolerance among selected Nigerian zebu. The polymorphisms were also used to determine genetic relationship among the animals. About 450 bp of bovine HSP 90 including part of coding region in exon 3 was sequenced in 90 DNA samples representing four Nigerian zebu namely White Fulani (WF), Sokoto Gudali (SG), Red Bororo (RB) and Ambala (AM). Sequencing was done using an automated ABI-DNA Sequencer. Editing was accomplished using chromatogram analyses on SeqMan Ngen Tool. Rooted phylogenetic tree was constructed using MEGA 5.2 software. In total, 11 genetic variants were determined. Five of these (PRP, RED, ORG, LMN and YLO) were major variants detected in over 70% of the samples. Six (6) were classified as minor variants detected in two breeds or less and in 29.1% of the samples. The GRN and NBL were only detected in RB and SG breeds respectively. We found a shared homology and common ancestral lineage among the breeds. Furthermore, the genetic structure of Nigerian zebu has a common clade architecture to those of goats, sheep, yak, buffalo, camel, horse and other taurines. The gene is conserved among wide range of animals and as such it can serve as one of bio-markers for selection and breeding programmes for thermotolerance in wide range of livestock animals under thermal stress. The variant groups could be further interrogated for possible specific effects on thermotolerance performance of zebu in hot tropical environments.

Genetic and Non Genetic Sources of Variation for Linear Body Conformation Traits in Bunaji and Friesian X Bunaji cows

Abstract: (ST, CW, BD, WH, HG, BL and RW). It is therefore suggested that in selecting for body conformation these genetic and non genetic factors should be taken into consideration.
