The control of respiratory infections is integral to a healthy livestock farm. current study was conducted optimize multiplex PCR assay for simultaneous detection Pasteurella multocida (P. multocida), Staphylococcus aureus (S. aureus) and Mycobacterium bovis (M. bovis) in nasal samples cattle having suspicion tract infections. were collected from 10 dairy farms affected with disease outbreaks the recent past. These associated caused by bacterial pathogens P. multocida, S. M. bovis. A...

The goal of this work was to understand how polymorphonuclear leukocytes (PMN), the first line cellular defence, integrate and prioritize multiple chemotactic signals navigate during periods demand like subclinical mastitis (SCM), clinical (CM), pregnancy (P), calving (C). For this, blood milk samples were collected from five groups crossbred cows (healthy, with SCM, CM, pregnant, newly calved). Maximum viability seen in PMN healthy cows, whereas minimum observed CM cows. Phagocytic activity...

Animals are susceptible to heat stress under tropical environmental conditions. Exposure of growing male and female animals severe during summer adversely affects their growth reproductive traits, reduces the resistance diseases induces infertility in farm represents a major source economic loss livestock sector. During season, usually suffer from sterility due prevailing hot humid In animal's age at puberty, estrous signs, ovulation time, ova quality, conception rate, embryonic development,...

Interferon tau, a 23 kDa trophoblast derived protein diffuses out from the uterus into circulation and leads to expression of IFNτ stimulated genes viz. ISG15 OAS1 in blood neutrophils. The pathway is species as well tissue specific. To unsnarl downstream signaling pathway, neutrophils were incubated simultaneously with 10 ng / ml recombinant bovine interferon tau inhibitors JAK2 (AG490), JAK3 (CP690550), p38 (SB202190), PI3K Akt (LY294002), MAPK Erk (U0126) at specific doses for 4‐hr...

Semen samples with mass motility of 4+ or more and an initial progressive ≥ 80% collected from murrah buffalo bulls were utilized for study. evaluated various seminal attributes, enzymatic antioxidants (superoxide dismutase, catalase glutathione peroxidase) total antioxidant capacity at fresh, pre-freeze post-thaw stage. Seminal attributes (progressive motility, viability, acrosomal integrity hypo-osmotic swelling response) significantly (p<0.05) higher in bull II as compared to (I & III)...

The seasonal breeding in sheep poses a challenge improving productivity, owing to the incomplete knowledge of mechanics breeding, effective strategies for increasing lamb crop are restricted. A major mechanism responsible reproduction is striking increase responsiveness gonadotropin-releasing hormone (GnRH) neurons negative feedback effects estradiol that peaks during anestrous and decreases season. Melatonin does not directly drive changes reproduction; rather it appears synchronize an...

Neutrophils (first line of cellular defense) are capable detecting presence foreign genome in the mother’s womb. Role neutrophils during full gestation cycle ruminants and difference their number, type, activity successful unsuccessful pregnancies is not known. To evaluate this, blood samples were collected at artificial insemination (0 day) on days 10, 14, 16, 18, 21 non-pregnant (NP) cows. However pregnant (P) cows, as indicated above every 30 for complete gestation. In aborted till...

The maternal immune response during pregnancy is regulated by a complex array of pro and anti-inflammatory cytokines which provide optimum conditions for the embryo implantation survival. possible role complete gestation cycle ruminants difference in their circadian rhythmicity between successful unsuccessful pregnancies still unknown. To study this, blood samples were collected from three groups cows, pregnant (P), non-pregnant (NP) aborted (ABORT) cows starting day Artificial Insemination...

AbstractThis study was designed to isolate, cultivate, characterize and evaluate the growth kinetics of mesenchymal stem cells (MSCs) derived from fetal adnexa sheep. The gravid uteri ewes were collected a local abattoir. MSCs isolated different regions (Wharton's Jelly [oWJ], cord blood [oCB], amniotic fluid [oAF] Sac [oAS]) expanded in vitro characterized for surface pluripotency markers. compared at 3rd 5th passages. Similarly, colony-forming efficiency (CFE) assay performed passage....
