Aim:This study was conducted to understand whether serum level of the steroid and metabolic hormones may be indicative of their level in ovarian follicular fluid (FF) in porcine, and its influence on fertility.Materials and Methods:Ovaries from pigs (n=32) of two genetic groups, namely, native (Ghungroo; n=16) and crossbred (Hampshire × Ghungroo; n=16) were collected. Both the genetic groups comprised gilts (n=8) and sows (n=8), and sows were in luteal phase of estrus cycle. FF was aspirated from small, medium and large follicles, and centrifuged for the collection of supernatant for further analysis. Blood samples were collected from the same animals, and serum was separated. Hormones, namely, cortisol, T3, T4 and testosterone were estimated by radioimmunoassay. Two-way ANOVA was used for analysis of data considering genetic background (native or crossbred), stage of reproductive life (gilt or sow), and source of sample (serum or FF) as fixed effects.Results:It was observed that all the hormones except cortisol differed significantly (p<0.01) based on genetic background. Stage of reproductive life and source of sample did not affect the studied hormonal level. Within the genetic groups, stage of reproductive life influenced T3 (p<0.01), cortisol (p<0.05) and testosterone (p<0.01) level in crossbred pigs as compared to T3 (p<0.01) only in native pigs. The level of T3 in serum, as well as FF, was higher (p<0.01) in Ghungroo gilts compared to sows. However, a reverse of this was observed in the case of crossbred pigs. The level of cortisol (p<0.05) and testosterone (p<0.01) was higher in crossbred sows than gilts in both serum and FF.Conclusion:The study revealed that serum level of the steroid and metabolic hormones is indicative of their level in the ovarian FF. Further, varying level of steroid and metabolic hormones in pigs based on genetic background may be due to variation in body size, rate of energy metabolism and stage of (re)productive life.

The objective of the study was to assess the variability in the physiological responses of growing pigs on melatonin and vitamin E supplementation during summer and winter seasons.36 nos. of weaned crossbred (Hampshire X Assam local) female pigs were selected for the study. Eighteen (18) animals were subjected to treatment separately during summer and winter. The selected animals were divided into three groups, with six pigs in each group, consisting of the control group (Treatment 1), a second group comprising of animals fed with melatonin (Meloset) @3 mg/animal (Treatment 2) and a third group in which the animals were fed Vitamin E (Evion) @100 mg (Treatment 3), for both the seasons. The rectal temperature, respiration and pulse rate differed significantly (P<0.01) between seasons. There was also significant difference (P<0.01) in the mean pulse rate between treatment.

: A field experiment was conducted at farmer's field during Rabi season of 2011-12 in Jorhat district to study the effect of different combinations of organic sources of nutrients viz., vermicompost, FYM, rock phosphate along with bio-fertilizer on different growth parameters, yield and profitability of French bean cultivar Arka Anoop. The experiment was laid out in Randomized Block Design with four treatments and five replications. In this investigation, the results revealed that application of vermicompost + FYM + Rhizobium + rock phosphate (T 2 ) significantly increased the germination percentage (87%), growth parameters and yield of the crop viz., plant height (37.50 cm after 60 days of sowing), number of branches plant -1 (6.48 after 60 days of sowing), green pod length (12.16 cm), green pod number plant -1 (20), green pod weight (300.05 g plant -1 ), dry weight of plant (18.74 g), number of seeds pod -1 (6.08) than the remaining three treatments. There was no significant difference in days to 50 per cent flowering among different treatments. However, nodulation was maximum in the treatment T 4 (41.88) and minimum in T 1 (38.20) . Nodules plant -1 in the treatment combinations T 2 and T 3 were at par. Highest yield (14 t ha -1 ) with maximum benefit : cost ratio (3.35:1) was obtained in the treatment combination T 2 and the lowest (7.00 t ha -1 ) was obtained in the treatment T 1 with minimum benefit : cost ratio (2.50:1). Though the yield was higher in the treatment T 3 than T 4 , yet the benefit : cost ratio was more in the treatment T 4 . It may be due to high cost of vermicompost than FYM.KEY WORDS : Vermicompost, FYM, Rhizobium, Growth, Yield, French bean HOW TO CITE THIS ARTICLE : Sarma, I., Phukon, M., Borgohain, R., Goswami, J. and Neog, M.
