Identification of potential differences in salivary proteomic profiles between estrus and diestrus stage of estrous cycle in dairy cows.

In the present study, a comparative global high-throughput proteomic analysis strategy was used to identify proteomic differences between estrus and diestrus stage of estrous cycle in dairy cows. Saliva was collected from cows during estrus and diestrus, and subjected to LC-MS/MS-based proteomic analysis. A total of 2842 proteins were detected in the saliva of cows, out of which, 2437 and 1428 non-redundant proteins were identified in estrous and diestrous saliva, respectively.

Mucin and salt combination simulate typical fern-like pattern of buffalo saliva smear at estrus.

Estrus detection in buffaloes primarily relies on behavioral and physiological signs. Especially during summer, these signs are less prominent to recognize. Thus, estrus detection is a pronounced challenge within the realm of buffalo husbandry, particularly in the summer.

Digital infrared thermal imaging of udder skin surface temperature: a novel non-invasive technology to monitor calving process in Murrah buffalo (Bubalus bubalis).

Quantifiable decline in the maternal body temperature during the pre-calving offers the possibilities for predicting the calving that can improve the calving management. As infrared thermography (IRT) is a simple non-contact tool for precise measurement of surface temperature, we investigated the use of IRT to establish thermal signatures around calving in the Murrah buffalo. The IRT of eye, right lateral, left lateral and rear side of udder skin surface temperature (USST) were recorded at 6 h interval from 96 h before the expected date of calving, at the time of calving and 24 h post-calving in Murrah buffaloes (n = 28).

Quantitative proteomics profiling of spermatozoa and seminal plasma reveals proteins associated with semen quality in Bos indicus bulls.

Cattle breeding approaches are an evolving field of research in veterinary science. Certain factors such as Ejaculate Rejection Rate (ERR) pose a limitation to such approaches. In this regard, we sought to investigate the spermatozoa and seminal plasma proteome of Hallikar bulls with low (n = 3) and high (n = 3) ERR.

Anti-Müllerian hormone as an endocrine biomarker of reproductive longevity and assessment of single nucleotide polymorphisms in AMH gene of Bos indicus breeds of cattle.

Anti-Müllerian hormone (AMH) is a member of the TGF-β superfamily produced by follicular granulosa cells in women and cattle and is considered an endocrine biomarker of ovarian follicular reserve. The study examined how age and parity influence serum AMH concentration and investigated the presence of single nucleotide polymorphisms in AMH gene in Bos indicus breeds viz Malnad Gidda Amritmahal and Hallikar. All five exons of AMH gene amplified by polymerase chain reaction were subjected to sanger sequencing and identified important SNP and its effects.

Effect of Dioxins in Milk on the 3D Cultured Primary Buffalo Hepatocyte Model System.

Cow and human milk have been reported to contain dioxins ranging from 0.023 to 26.46 and 0.
