The objective of this work was to characterize Pantaneiro cattle genetically through its paternal ancestry by the morphology of the Y chromosome, whether submetacentric or acrocentric, as well as to identify the maternal ancestry through mitochondrial DNA. The karyotype and mitochondrial DNA of 12 bulls of Pantaneiro breed were analyzed. The Y chromosome was analyzed in lymphocyte metaphases and the mitochondrial DNA by diagnosing its haplotype (Bos taurus and Bos indicus). Among Pantaneiro animals analyzed three had a taurine (submetacentric) Y and nine had a zebuine (acrocentric) Y chromosome, suggesting breed contamination by Zebu cattle, once Pantaneiro is considered to be of European origin. The mitochondrial DNA was exclusively of taurine origin, indicating that the participation of zebuines in the formation of the breed occurred entirely through the paternal line.

Background: Molecular markers based approaches are essential to select fertile bulls for frozen semen production at an early age. The present investigation was undertaken to perform the molecular characterization and identify single nucleotide polymorphisms (SNP) in Y-chromosome specific DDX3Y gene in Murrah buffalo bulls. Methods: The genomic DNA isolated from the blood samples of 70 Murrah buffalo bulls, covering bulls with normal seminal traits and poor production performance (poor semen quality, freezability, libido), were subjected to PCR amplification. The sequences of DDX3Y gene were analyzed for single nucleotide polymorphism using the seqman module of DNASTAR LASERGENE software. The single nucleotide variations in the sequences with reference to the Bos taurus sequence were determined using Clustal W. The phylogenetic tree and genetic distance were constructed using the MegAlign module. Result: The analysis of sequences revealed that the exons and their adjacent intronic regions of the DDX3Y gene are monomorphic in nature without any variations indicating that the sequences are highly conserved in the studied population of Murrah buffalo bulls. However, a considerable number of single nucleotide variations were observed in the sequences of Murrah buffalo compared with Bos taurus sequences. Furthermore, the phylogenetic tree analysis revealed less divergence and close genetic association between the sequences of Murrah buffalo and other species in the bovinae family than the caprinea species. Further studies on DDX3Y gene in a more extensive and diverse population of Murrah buffalo bulls distributed in different regions could aid to discover substantial SNPs.

Calving Rate

Calving data recorded over a 28-year period were analysed for the effects of breed, filial generation, lactational status, cow liveweight at mating and year of mating. The herd comprised six distinct breeding lines ('breeds') and analysis was performed both within and across breeds. The least fertile breeds were the high grade (314-718) Africander (A) and high grade (718-purebred) Brahman (B) cows which had average calving rates of 56% and 55%, respectively. Crossing these with a Hereford- Shorthorn line, which had an average calving rate of 6O%, resulted in 19% heterosis (in absolute calving percentage units) in the F1 Africander-cross (AX) and 16% heterosis in the F1 Brahman-cross (BX). In subsequent generations, 13% residual heterosis remained in the AX, while in the BX only 1% remained. Reciprocal crossing of the AX and BX lines generated 6% heterosis in the Fl AXBX, and all of this was maintained in subsequent generations. In the F2 et seq. generations of the AXBX, the line of animals carrying the Bos indicus Y chromosome was similarly fertile (P> 0.05) to the line carrying the Bos taurus Y chromosome. Lactating mature (3 5-year-old) cows were on average 15% less fertile than non-lactating cows. This lactation effect was larger in younger cows. There was a curvilinear response in fertility to increasing liveweight at mating which was most pronounced in 2-year-old heifers. Breed appeared to react differently to the effects of environmental stress where the AX and HS cows were limited more by liveweight, and the BX and AXBX were more limited by lactation effects per se. Lactating cows that also lactated in the previous year were 6% more fertile than lactating cows that were dry the previous year, suggesting that calving records are moderately repeatable and therefore that permanent differences in fertility could be established by phenotypic selection.

Nonsense Mutations

Amplified gene families on sex chromosomes can harbour genes with important biological functions, especially relating to fertility. The HSFY family has amplified on the Y chromosome of the domestic pig (Sus scrofa), in an apparently independent event to an HSFY expansion on the Y chromosome of cattle (Bos taurus). Although the biological functions of HSFY genes are poorly understood, they appear to be involved in gametogenesis in a number of mammalian species, and, in cattle, HSFY gene copy number correlates with levels of fertility. We have investigated the HSFY family in domestic pigs, and other suid species including warthogs, bushpigs, babirusas and peccaries. The domestic pig contains at least two amplified variants of HSFY, distinguished predominantly by presence or absence of a SINE within the intron. Both these variants are expressed in testis, and both are present in approximately 50 copies each in a single cluster on the short arm of the Y. The longer form has multiple nonsense mutations rendering it likely non-functional, but many of the shorter forms still have coding potential. Other suid species also have these two variants of HSFY, and estimates of copy number suggest the HSFY family may have amplified independently twice during suid evolution. Given the association of HSFY gene copy number with fertility in cattle, HSFY is likely to play an important role in spermatogenesis in pigs also.
