Present study was carried out to evaluate the effect of Zinc (Zn) supplementation on hormonal and lipid peroxidation status of peri-parturient KF (Karan Fries) cows during heat stress. Cows were grouped as C (6), T1 (6) and T2 (6). C was fed basal diet alone; however T1 and T2 were fed with 80 ppm and 120 ppm Zn, respectively along with basal diet from 45 days prepartum to 45 days postpartum. It was found that Zn level was significantly (P<0.05) higher in supplemented group than control. Plasma cortisol was significantly (P<0.05) reduced in T2 compared to C and T1 at calving. T 3 and T 4 concentration decreased at pre-partum, increased at post-partum and was significantly (P<0.01) higher in T2 followed by T1 and C. TBARS level was significantly (P<0.01) lowered in T1 and T2 compared to control at postpartum. Result indicated that amelioration of heat stress by supplementation of Zn through reduced cortisol, TBARS and improved T 3 & T 4 concentration.

Present study was conducted to investigate the seasonal effects of transportation of goats (Alpine x Beetle) at different flocking densities, supplemented with Vitamin C in group I, Vitamin C + Electrolyte in group II and Jaggery in group III, 3 days before transport of animal, during winter and hot-humid seasons. The goats were selected from LRC, NDRI Karnal and were of 10-12 months old. Each group consisted of 25 goats each, divided into high (15) and low (10) flocking densities, transported for 8h with average speed of 25 Km/h. All the animals were kept off-feed and deprived of water during the transportation period. Physiological responses (Respiration rate, Rectal temperature, Pulse rate and Skin temperature) were recorded before and after transportation. A significant increase (P less than 0.05) in ST, RT, RR and PR were recorded just after unloading in both the flocking density groups and during both seasons which then declined to basal values (P less than 0.05) within 6-12 hours post transportation. Supplementation with Vitamin C, Vitamin C + Electrolyte and Jaggery aided in reducing transportation stress but Vitamin C + Electrolyte combination proved more beneficial in alleviating transportation stress in the goats.

A study was conducted to investigate the growth parameters, mortality and recruitment pattern of Odontobutis potamophila collected in the Gaosha river fish landing site, west part of Wuyuan County (Latitude: 29° 14' 29" N, Longitude: 117° 45' 49" E). O.potamophila were collected from November, 2013 to October, 2014. Growth parameters, asymptotic length (L ) = 192mm and growth coefficient (k) = 0.22 year -1 . Growth performance index(Ø') =3.91, total mortality (Z) = 0.72 year -1 , natural mortality (M) = 0.32 year -1 , fishing mortality (F) = 0.40 year -1 and exploitation rate (E) = 0.55year -1 .The estimated exploitation rate (E) has slightly exceeded the optimum value of E indicating this species was sustainable exploitation in the study area. The exploitation ratios were computed as E max = 0.61, E 10 = 0.52, E 50 = 0.34. The length at first capture at 50%, (L c ) was 77 mm. The recruitment pattern of the species was found continuous all-round the year with one peak. The observation of the annual recruitment of O.potamophila found to occur from May to July. Steady biomass also increased with length class until 121-125 mm, and the total steady state biomass was found to be 2240 kg.
