    Abstract: Brucellosis has long been recognized with high seroprevalence in Indian dairy herds. Serological surveillance followed regularly to monitor the status of the disease. Four serological methods viz., ELISA, RBPT, STAT and 2-ME tests were used to determine the seroprevalence of brucellosis in an organized dairy farm. Overall, 33.85%, 32.61% and 30.90% animals were diagnosed serologically positive, respectively by ELISA, RBPT and STAT. However, only 13.66% animals were diagnosed positive by 2-ME. Maximum numbers of seropositive cases were found in female animals, indigenous breed and in 6 to 〈 9 yrs age group, respectively by all serological tests. ELISA diagnosed highest number of seropositive cases in different categories viz., females (36.41%), indigenous breed (21.13%) and 6 to 〈 9 yrs (52.15%), respectively. Sex, breed and age of animals were found to influence the antibody titer (, p 〈 0.05) of animals. Therefore, ELISA could be recommended as a screening test for cattle. However, at field level RBPT (, 0.8597) and STAT (, 0.8608) may be used for initial screening of the herd. In addition, 2-ME test must be used in parallel to other serological test to rule out the infection.

    Abstract: An experiment was carried out to evaluate the effect of seed priming with magnesium nitrate salt against the moisture stress condition induced by Polyethylene glycol-6000 on seed germination, vigour index and tolerance index in root and shoot. Polyethylene glycol-6000 was used to create short term moisture stress under laboratory conditions while the seed priming was carried out by using magnesium nitrate. The percent germination, seed vigour index and tolerance index were started to decline from T1 to T4 (i.e. set first 1.5 and 4.5 % of PEG-6000 solution + none primed seed) while the results of second set (i.e. PEG-6000 + primed seed from T5 to T8) were also following the same decreasing trend along with improvement in every parameters. The germination was recorded highest 100 percent in T5 (i.e. 1.5% PEG-6000+ primed seed) followed by T6, T1 and T7 (T6 and T7 is 2.5% and 3.5 % PEG-6000+ primed seed) while the control set recorded 98.7% at final date of observations i.e. 240 Hrs. vigour index and tolerance index was also decreasing in both the set of treatments but PEG-600 + primed seed showed better results as compared to the treatments PEG-6000 + none primed. Tolerance index percent was recorded maximum in root as compare to shoot at 120 hrs. of intervals while the reverse result was recorded at 240 hrs. of intervals.

    Abstract: Availability of morphologically normal and higher percentage of live spermatozoa throughout the year is highly demanded to fulfilment the demand of dairy cattle. There may be deterioration of semen quality during summer season in crossbred bulls in tropical climatic condition. Therefore the present study was designed to observe the seasonal effect on viability and morphology of spermatozoa in Karan Fries bulls. Five adult healthy bulls (n=5) were selected from Animal Breeding Research Centre (ABRC) of ICAR-NDRI, Karnal, Haryana (India). Six ejaculates from each bull were collected using artificial vagina (42-45 °C) during winter (December to Middle February), spring (Middle February to April), hot-dry (May to June) and hot- humid (July to August) seasons. Immediately of collection, the ejaculates were placed in a water bath (37 °C). Eosin-nigrosin vital stain was used for assessing live, dead and sperm abnormalities. The percentage of live spermatozoa were significantly (p 〈 0.05) lowered during hot humid season and the major abnormalities were significantly (p 〈 005) higher during hot-dry (8.66 ± 0.22 %) and hot-humid (10.74 ± 0.18 %) seasons. It can be concluded that hot-dry and hot-humid seasons are stressful to Karan Fries bulls. Therefore, sufficient measures should be taken to ameliorate the effect of heat stress on Karan Fries bulls.

    Abstract: In order to study the plasma hormonal and metabolic changes in Zebu (Sahiwal) cattle during summer and winter season, five each of periparturient high and low yielding cows were selected from Livestock Research Centre, ICAR-NDRI, Karnal. Blood samples were collected on days -45, -30, -15 (prior to parturition), 0 (day of parturition) and 15, 30, 45 (postpartum) during both the seasons and plasma was separated. Plasma cortisol levels were significantly higher on day of parturition and during postpartum period in both the groups during both the seasons. Plasma insulin levels were significantly (P less than 0.05) lower during summer in high yielder group. On the day of calving, plasma T3 and T4 levels were significantly (Pless than 0.05) lower in high yielders during both seasons. Plasma leptin levels were lower (Pless than 0.05) on day of parturition in high yielders than low yielders during both seasons. Plasma glucose levels were significantly lower (Pless than 0.05) on day of parturition and remained low during postpartum period in both groups during both seasons comparel to prepartum period. Plasma NEFA levels of both groups of cows were higher on the day of calving and remained higher during postpartum period over pre calving values. High yielder cows showed more deviation in stress markers viz. cortisol and NEFA than low yielder cows. Therefore, special attention should be given to feeding and management of the lactating animals (especially high yielding cows during summer) around parturition for sustained productivity and maintenance of homeostasis.

    Abstract: A field experiment was conducted during rainy seasons of 2011 and 2012 at Udaipur to evaluate the effect of weed control and sulphur on yield and quality of soybean [Glycine max (L.) Merrill]. The twenty eight treatment combinations comprising 7 weed management treatments (weedy check, pendimethalin 1.0 kg ha-1 pre- emergence, quizalofop-ethyl 50 g ha-1 and imazethapyr 100 g ha-1 post-emergence at 15 DAS, pendimethalin, quizalofop-ethyl and imazethapyr followed by hoeing and weeding at 30 DAS) in main plot and 4 rates of sulphur application (00, 20, 40 and 60 kg ha1) in sub plot were laid out in split plot design with three replications. All weed control treatments reduced weed dry matter at harvest during both the years. Pendimethalin followed by hoeing and weeding at 30 DAS was significantly superior in reducing weed dry matter of broad-leaved, narrow-leaved and total weeds at harvest over rest of the treatments. All weed control treatments significantly enhanced straw and biological yield of soybean over weedy check. Pendimethalin followed by hoeing and weeding at 30 DAS produced significantly higher pooled seed (2168 kg ha-1), straw (3167 kg ha-1) and biological (5335 kg ha-1) yields compared to other treatments. Sulphur rates had no significant effect on weed dry matter at harvest. Across the years, increasing level of S application up to 40 kg ha-1 resulted in significantly increased straw yield, biological yield and harvest index of soybean. Increasing rate of sulphur application up to 40 kg ha-1 tended to significantly increase protein and oil yield.

    Abstract: The present investigation has been aimed to study the effect of replacing khoa with skim milk powder on sensory characteristics and chemical composition of fresh bottle gourd halwa. Control bottle gourd halwa from khoa (To) and four lots of experimental bottle gourd halwa samples were manufactured by incorporating skim milk powder (in the form of reconstituted skim milk) at 10 (T1), 20 (T2), 30 (T3) and 40 (T4) per cent (w/w) of shredded bottle gourd. The fresh bottle gourd halwa samples were analysed for sensory (colour and appearance, body and texture, flavour and overall acceptability) and chemical (moisture, fat, protein, total carbohydrate and ash) qualities. The product prepared using 20% SMP (w/w) of shredded bottle gourd was found most acceptable on the basis of overall acceptability among the experimental products and at par (Pandgt;0.05) with the control product. Proximate analysis indicated that on increasing the proportion of SMP; fat and moisture showed a decreasing trend and reverse in case of protein, total carbohydrate and ash contents. As the level of SMP increases the cost of bottle gourd halwa also increased.
