Environmental temperature is one of the important abiotic factors that influence normal physiological function and productive performance dairy cattle. Temperature stress evokes complex responses are essential for safeguarding cellular integrity animal health. Post-transcriptional regulation gene expression by miRNA plays a key role responses. The present study investigated differential in Frieswal (Holstein Friesian × Sahiwal) crossbred cattle distinctly adapted to environmental as they...

microRNAs (miRNAs) are a class of small non-coding RNAs that play key roles in post transcriptional gene regulation influence various fundamental cellular processes, including the responses during environmental stresses. However, perusal literatures revealed few reports on differential expression miRNA thermal stress Indian native (Bos indicus) cattle breeds. The present investigation aimed to identify differentially expressed miRNAs Sahiwal dairy breed India, adapted with tropical climate...

In a recent publication, we reported the successful use of tetra primer-amplification refractory mutation system based polymerase chain reaction (T-ARMS-PCR) for genotyping rs445709131-SNP responsible bovine leukocyte adhesion deficiency (BLAD) in cattle. The SNP is characterized by higher GC content surrounding region, hence, previous protocol utilized dimethyl sulfoxide as PCR enhancer. Here, cocktail was modified with thermostable strand displacement (SD polymerase) instead commonly used...

Contents Mammalian circadian locomotor output cycles kaput ( CLOCK ) gene encodes a transcription factor that affects both the persistence and period of rhythms. Earlier reports suggested might be associated with male infertility in human. Present investigation, for first time, expresses differentially between good poor quality crossbred bull semen. The relative expression was significantly (p < 0.05) higher among semen than motility‐impaired ones. Clusterins CLU are series genes variety...

Abstract Background DNA testing in the cattle industry undergoes multiple hurdles. Successful genotyping involves transportation of samples from field to laboratory a chilled environment followed by extraction, and finally, specific protocol is followed. Various researches are focused on overcoming these issues. Microcards offer blood at ambient temperature. Direct PCR methods can save time extraction but available only for simplex PCR. Tetra Primer-Amplification Refractory Mutation System...

Abstract Calcium channel, voltage-dependent, alpha-2/delta subunit 1 (CACNA2D1) gene is considered to be an important noncytokine candidate influencing mastitis. Scanty of reports are available until today regarding the role play CACNA2D1 on susceptibility bovine We interrogated G519663A [A > G] SNP by PCR-RFLP among two hundreds Frieswal (HF X Sahiwal) crossbred cattle Indian origin. Genotypic frequency AA (51.5, n = 101) was comparatively higher than AG (35, 70) and GG (14.5, 29)....

A diagnostic method for simultaneously detecting and distinguishing African Swine Fever (ASF), porcine circovirus type 2 (PCV2), parvovirus (PPV) in clinical specimens is critical differential diagnosis, monitoring, control the field. Three primer pairs were designed used to create a multiplex PCR assay. In addition, 356 post mortem tissue samples from various parts of India's North Eastern region tested by developed assay demonstrate its accuracy. Using primers, each ASF, PCV2 PPV target...

The surface expression of CD9 (cluster-of-differentiation antigen-9) in sperms certain mammalian species has been attributed to its fusion with the egg and thereby dictating fertility species. In present study, we investigated association crossbred bull sperm quality quantity trait was analyzed using a total 96 Frieswal (HF × Sahiwal) crossbred. A single nucleotide polymorphism (g.358A > T) intron 6 significantly associated concentration (P < 0.05) motility percentage 0.01). mRNA extracted...
