SummaryHassawi cattle breed is a mix of Bos indicus and Bos taurus. The cattle are raised in the Eastern province of the country by farming families in mixed farming system. The breed numbers are declining very fast, from 10 449 head in 1986 to an estimated maximum of 4 500 head at present.The decrease is mainly due to replacement by exotic breeds, the indiscriminate crossing with these exotics, particularly in view of the scarcity of the Hassawi bulls for mating. Animals are small in size, mature body weight 210-270 kg for bulls and 150-200 kg for cows, quite uniform in colour (light red) and body conformation have conspicuously reduced dewlap and umbilical folds and relatively large hump. Animals are heat tolerant, sustain high feed intake under ambient temperature, resistant to many diseases prevailing in the region and cows have good mothering ability. Productivity of the breed in terms of meat and milk is low when compared to that of exotics in high input production environments, but reproduction performance excels that of temperate breeds and zebu cattle.Efforts should be made to stop the decline in the breed numbers and to conserve the breed as an asset for production under harsh environment.

Abstract. In mammals, especially dairy cattle the prolactin has important functions like the development of mammary gland affecting milk yield and composition. It has been mapped to chromosome 23 in Bovine (HALLERMAN et al., 1988). A silent A→G transition mutation at the codon for amino acid 103 in exon 3 of bovine prolactin (bPRL) gene gives rise to a polymorphic Rsa I site, has become a popular genetic marker used for genetic characterization of cattle populations by means of PCR-RFLP (MITRA et al., 1995; CHRENEK et al., 1998; DYBUS, 2005). The present study reports on the genotype frequencies observed in various Bos taurus and Bos indicus dairy cattle breeds.

Naturally, the fertility of Aceh cattle has declined and caused huge losses in the development of Aceh cow germplasm. Several genetic-based studies have been carried out in Aceh cattle, including characteristics of genetic diversity using microsatellite DNA and its relationship to body weight in Aceh cows, but there is no research on genomics that is closely related to fertility, especially fertility in aceh cows. Previous studies have revealed a correlation between fertility with the expression of several genes involved in spermatogeneses such as Protamines (PRM 1, 2, and 3) and Transition Nuclear Proteins (TNPS 1 and 2). This study aims to identify the PRM1 gene that plays an important role in spermatogenesis and the fertility status of Aceh cattle. This research was carried out using 10 Aceh cattle testes taken from slaughterhouses, followed by DNA isolation, amplification of the PRM1 gene, DNA sequencing, and DNA base sequence analysis. The result showed that the nucleotide sequences of aceh cattle PRM1 gene did not differ from the PRM1 gene from Bos taurus and Bos indicus in the GeneBank. Analysis of protein sequences showed that PRM1 in Aceh cattle sperm is rich in the amino acid arginine, which is 36.92%. From this study, it can be concluded that the PRM1 gene from Aceh cattle is identical to the PRM1 gene from Bos taurus and Bos indicus both at the DNA sequence level and at the protein sequence.

Background: Forebrain embryonic zinc finger-like (FEZL) gene is an important candidate associated with mastitis resistance in dairy cattle. FEZL is involved in transcriptional regulation of neuronal development and there exists a crosstalk between neuronal development and immunity via downstream cytokine expression. A single glycine insertion into glycine stretch of FEZL gene has large effect on downstream cytokine pathway making the cows susceptible to mastitis. The present study was aimed to sequence characterize FEZL gene in Sahiwal (Bos indicus) and Karan Fries (Bos inidcus X Bos taurus) cattle.Methods: Sequence characterization of bovine FEZL gene was carried out by primer walking method. Ten sets of oligonucleotide primers were designed to synthesize overlapping fragments and generate the complete sequence of about 3.7 kb covering all exons and 5’ upstream regulatory and flanking regions.Result: A total of eight nucleotide variations including three INDELS and five substitution mutations were observed among FEZL gene sequences of Bos taurus, Bos indicus (Sahiwal) and Bos taurus X Bos indicus (Karan Fries) cattle. The conceptualized amino acid sequence of bovine FEZL gene in Sahiwal and Karan Fries cattle was found to have 13 tandem Glycine residues and a serine to proline change within exon 1 region. The percent identity of FEZL gene of Sahiwal and Karan Fries cattle was 99% with that of Bos taurus, 95% with dog, horse and pig, 94% with human, 93% with rabbit, 92% with marmoset, 89% with rat and 79% with chicken. Sequence characterization of ~0.7 kb 5’ flanking region showed that it is highly conserved among bovines and resulted in prediction of six putative sites for binding of transcription factors (including Elk-1, Oct-1, HNF4, Lmo2 complex, GATA-3 and Nkx2-5). Elucidation of Bos indicus FEZL gene will further form the basis to identify candidate gene markers for association with mastitis resistance/susceptibility in cattle.

The study provides the first comprehensive information on the variability of milk protein genes of Bos indicus and Bos taurus cattle breeds in Cameroon and Nigeria. The investigations indicate a high diversity of milk protein genes for the zebu populations. Of the investigated alleles, 21 out of 29 were observed. The method of single strand conformation polymorphism (SSCP) was a particularly useful technique because it allowed discrimination of alleles, including zebu-specific alleles at the CSN2 (I) and CSN3 (AI and H) loci, not separated by protein electrophoretic techniques and also made possible the detection of a further CSN1S1 5′ promoter allele (CSN1S1Prom5), which is also zebu-specific. Characterization of CSN1S1Prom5 showed that it was the most variable of all described CSN1S1 promoter alleles. A potential GATA consensus motif is created by mutations in CSN1S1Prom5. Intra-breed diversity measured as mean effective number of alleles was higher in the zebu populations than in the taurine breeds. Of the expected casein haplotypes, 96 out of 320 were present in the studied breeds. 2-C-A-A2-H (CSN1S1Prom2-CSN1S1C-CSN1S2A-CSN2A2-CSN3H) and 5-C-A-A2-H were zebu-specific while 1-B-A-A2-B was specific to the taurines. Overall distribution of alleles and haplotypes clearly separated the zebu populations from the taurine breeds. Zebu influence on the taurine breed Namchi was detected through the occurrence of zebu alleles and haplotypes. High variability of milk proteins also means availability of resources for breed development, phylogenetic studies, and conservation and management decisions.

Abstract Background Cyclin-dependent kinases (CDKs) are protein kinases regulating important cellular processes such as cell cycle and transcription. Many CDK genes also play a critical role during adipogenic differentiation, but the role of CDK gene family in regulating bovine adipocyte differentiation has not been studied. Therefore, the present study aims to characterize the CDK gene family in bovine and study their expression pattern during adipocyte differentiation. Results We performed a genome-wide analysis and identified a number of CDK genes in several bovine species. The CDK genes were classified into 8 subfamilies through phylogenetic analysis. We found that 25 bovine CDK genes were distributed in 16 different chromosomes. Collinearity analysis revealed that the CDK gene family in Bos taurus is homologous with Bos indicus, Hybrid-Bos taurus, Hybrid Bos indicus, Bos grunniens and Bubalus bubalis. Several CDK genes had higher expression levels in preadipocytes than in differentiated adipocytes, as shown by RNA-seq analysis and qPCR, suggesting a role in the growth of emerging lipid droplets. Conclusion In this research, 185 CDK genes were identified and grouped into eight distinct clades in Bovidae, showing extensively homology. Global expression analysis of different bovine tissues and specific expression analysis during adipocytes differentiation revealed CDK4, CDK7, CDK8, CDK9 and CDK14 may be involved in bovine adipocyte differentiation. The results provide a basis for further study to determine the roles of CDK gene family in regulating adipocyte differentiation, which is beneficial for beef quality improvement.
