Filtration techniques are advantageous over colloidal centrifugation in improving freezability of low-quality buffalo bull () ejaculates.

The study compared efficacy of three sperm selection techniques in improving freezability of low-quality Murrah buffalo bull ejaculates. Sephadex (SEP), Sephadex ion-exchange filtration (SIE), and 40/80% gradient centrifugation protocols were standardized (ejaculates, =24). In Experiment-I, Sephadex G-75, G-100, and combined Sephadex G (75-100) column filtrates were compared.

Salivary cell-free and transcripts as potential biomarkers for estrus identification in buffaloes ().

Estrus detection is a major problem in buffaloes because of the poor expression of estrus signs leading to low reproductive efficiency. Salivary transcripts analysis is a promising tool to identify biomarkers; therefore, the present study was carried out to evaluate their potential as estrus biomarkers. The levels of , , , transcripts were compared in saliva during estrous cycle stages [early proestrus (day -2, EP), late proestrus (day-1, LP), estrus (E), metestrus (ME) and diestrus (DE)] of cyclic heifers ( = 8) and pluriparous ( = 8) buffaloes by employing quantitative real-time polymerase chain reaction (qRT-PCR).

Comparative Proteome Profiling of Saliva Between Estrus and Non-Estrus Stages by Employing Label-Free Quantitation (LFQ) and Tandem Mass Tag (TMT)-LC-MS/MS Analysis: An Approach for Estrus Biomarker Identification in .

Accurate determination of estrus is essentially required for efficient reproduction management of farm animals. Buffalo is a shy breeder and does not manifest overt signs of estrus that make estrus detection difficult resulting in a poor conception rate. Therefore, identifying estrus biomarkers in easily accessible biofluid such as saliva is of utmost interest.
