To evaluate the role of dietary supplementation of astaxanthin, prill fat and their combination on antioxidants and immune status of lactating buffaloes during heat stress. Twenty four lactating buffaloes (first to fourth parity) were selected and divided equally into four groups i.e. Group I (control), Group II (astaxanthin 0.25 mg/kg body wt/day), Group III (prill fat 100 g/animal/day) and Group IV (astaxanthin + prill fat). Plasma was separated from the blood collected at fortnightly interval for the analysis of antioxidant enzymes and interleukins levels. The levels of superoxide dismutase and catalase were significantly lower in astaxanthin supplemented groups (Group II and Group IV) compared to Group I and Group III. The levels of pro-inflammatory cytokine (Interleukin-2) was significantly (P LT 0.05) lower in astaxanthin supplemented groups (Group II and Group IV) compared to Group I whereas levels of anti-inflammatory cytokines (Interleukin-10) was significantly (P LT 0.05) higher in all supplemented groups (Group II, Group III and Group IV) than Group I. Results showed that, dietary supplementation of astaxanthin (potent antioxidant) was able to alleviate the heat stress induced changes by lowering the levels of antioxidant enzymes (SOD and CAT) and pro-inflammatory cytokine (IL-2) and improving the levels of anti-inflammatory (IL-10) cytokines in lactating buffaloes during summer season.

This study was conducted to assess the therapeutic efficiency of antioxidant in subclinical mastitis. Therapeutic trials were conducted in twelve buffaloes affected with subclinical mastitis and were randomly divided into two groups. The buffaloes of Group 1 were treated with intramuscular injection of Inj. Mofoi 5 mg/kg body weight, while Group 2 buffaloes were treated with intramuscular administration of Inj. Mofoi 5 mg/kg body weight along with antioxidant powder orally. The therapeutic efficacy was assessed based on bacteriological cure and the pre and post therapeutic values of somatic cell count, electrical resistance, pH and milk yield. The use of antioxidant along with Moxifloxacin was found to be superior than antibiotic alone by improving udder's natural defence mechanism, early restoration of milk yield and quick recovery.

This study was undertaken to investigate the effectiveness of polypropylene mesh (PPM) for the repair of external abdominal hernias in buffaloes. PPM was used for the repair of external abdominal hernias in ten Jaffarabadi buffaloes having mean weight of 388.5 kg and mean hernial ring size of 117.279 cm2. Clinical, hematological, biochemical and erythrocytic antioxidants parameters were evaluated before and on post-implantation days 7 and 15 to assess efficacy of the repair. With the exception of one case, healing was uneventful. Hematological, biochemical and erythrocytic antioxidants findings were unremarkable. Polypropylene mesh shows excellent repair efficiency for external abdominal hernia repair in buffaloes without serious complications.
