This study documents the effect of cryopreservation on motility, DNA integrity, and gene expression in Mugil cephalus sperm. Fresh sperm were cryopreserved using V2 extender (V2E) or 0.3 M glucose, each in combination with one of three cryoprotective agents (CPAs), i.e., 10 % of dimethylsulfoxide, ethylene glycol, or glycerol, all at once. After tw...

The present study was carried out to assess the effect of rearing systems, breeds, number of pregnancies, and frequency of multiple births on physiological oxidative stress markers (OSMs) in indigenous goat breeds of Andaman and Nicobar Islands, India. Does (n=98) with more than one kidding record maintained in the organized goat breeding farm and...

The present study assessed the physiological antioxidant status of goats reared under the humid tropical island ecosystem of the Andaman and Nicobar Islands (ANI). From 2019 to 2020, 25 multiparous non-pregnant does with three to six kidding records maintained in the organized farm of Central Island Agricultural Institute (CIARI) and farmer’s field...

It is vital to identify the ejaculate with good freezability by determining the biochemical makeup of the ejaculate at the pre-freeze stage. The present study targeted to assess the use of the protein estimates and profiles at the pre-freeze stage as markers of freezability in Frieswal populations. Storing the proteins for proteomic studies is alwa...

The present study aimed to measure and compare alkaline phosphatase (ALP) enzyme activity in the bull’s semen with varying freezability. Based on the post-thaw motility percentages, the bulls of similar age groups were grouped into good and low freezable semen groups (Freezegroups). A total of 450 ejaculates from 21 bulls, with an average of 22 eja...

Hematological profiles of Andaman local goats of Bay Islands was carried to determine the influence of the feeding system (farm vs field), breed admixture (ALG vs other admixture), and parity (1-3 vs >3) on white and red blood cell profiles. Significant (P≤ 0.05) differences were evident in white blood cells (WBC) of farm animals. However there is...

Despite many cryopreservation techniques in bovine semen, various stressors' detrimental effects remain a significant issue. The present study targeted to assess the role of semen quality parameters, sperm function tests, lipid peroxidation, reactive oxygen species (ROS), and different antioxidants in the cryopreservation of bovine semen. Further,...

Equine influenza (EI) is an important viral respiratory disease of equines caused by influenza A virus. The antigenic drift in IAVs necessitates regular updating and harmonization of vaccine strain with the circulating virus. The reverse genetics-based aluminium hydroxide gel and challenged with H3N8 virus (A/eq/Jammu-Katra/06/08). The protective e...

Abstract For proteome analyses, the tissue samples are mostly preserved either snap frozen or formalin-fixed, paraffin-embedded form. Use of RNAlater—a non-toxic solution primarily used to stabilize the RNA content of samples—in tissue preservation for proteome analysis recently described equally reliable with snap-frozen preservation in human tiss...

Porcine circovirus type 3 (PCV3), a novel circovirus has been reported recently from major swine growing countries globally and the virus is associated with diseases like porcine dermatitis, nephropathy syndrome and reproductive failure. This report describes the identification of PCV3 associated with reproductive failure in sows and piglet mortali...

Equine influenza is a leading cause for respiratory illness in equines. Major control measures involve vaccination which requires continuous harmonization owing to antigenic drift. The present study focused on assessing the protective efficacy of an inactivated recombinant equine influenza virus (rgEIV) vaccine candidate adjuvanted with MontanideTM...
