This study was conducted to investigate the influence of strain on production traits, egg fertility, hatchability, dressing percentage, survival and docility of indigenous Guinea fowls in Ghana. A total of 700 keets (F1 generation) hatched from four strains of indigenous Guinea fowls were randomly picked from a large population at a day old and reared for 32 weeks. At 8th weeks, after mating, 600 keets (300 males and 300 females) were used for the study. The birds were separated into four strains (Pearl, Lavender, White and Black). Based on their numbers, the Pearls were replicated ten times, both Lavender and White five times each and the Black four times in a completely randomise design. There were 25 birds per replicate. In total there were 250 Pearls (125 males and 125 females), 125 Lavenders (62 males and 63 females), 125 Whites (63 males and 62 females) and 100 Blacks (50 males and 50 females). Data were analysed using the General Linear Model (GLM) procedure of SAS. The results showed that at 8th week the Pearl and the White had significantly (p<0.05) higher body weight and daily weight gain. However, at 16th, 24th and 32th week body weight was significantly (p<0.05) highest in Pearl strain. Age at first egg was significantly (p<0.05) earlier in the Lavender than the Pearl, White and Black but delayed in the Pearl. Again, the Pearls were significantly (p<0.05) superior in egg weight, percentage hen day egg production and fertility. No significant differences were observed in post-brooding daily weight gain, feed intake, FCR, docility by heterophil/lymphocyte ratio and post-brooding survival of the strains. Hatchability was significantly (p<0.05) higher in the Black. The White strain had significantly (p<0.05) better dressing percentage. Pre-brooding survival was significantly (p<0.05) higher in the Pearls and lower in the Black. Lavender was docile (p<0.05) as compared to the other breeds. It was concluded that given the same treatment, the Pearl strain had the potential to perform fairly well in most of the traits studied, hence are recommended for higher production while the Black strain should be used for hatchability and the Lavender for docility improvement.

Forecast models play a fundamental role in anticipating the effects of the energy demand in buildings to addressing the energy crisis. A forecast model for anticipating from one to three days every 30 min of the building energy demand is presented. In this model, a feed-forward artificial neural network (ANN) is combined with bootstrap aggregation techniques, using a Box–Cox transformation, seasonal and trend decomposition using loess, and a moving block bootstrap technique. An analysis was conducted using the data provided by a building’s energy demand; the data were collected during a period of four months, with readings every 10 s and averages of the values obtained every 30 min. The feed-forward neural-network method combined with bootstrap aggregation techniques consistently outperformed the forecasting accuracy of the original feed-forward neural network through cross-validation in the root mean square error (RMSE) and the mean absolute percentage error. From cross-validation in-sample period, used for the initial parameter estimation and model selection, it is concluded that a feed-forward neural network with the original data gives a slightly lower RMSE compared with the data generated by bootstrapped versions. However, in the cross-validation out-of-sample period used to evaluate forecasting performance, it has better consistency throughout all horizons for the ANN model combined with bootstrap aggregation techniques than for the ANN original model. The results are statistically significant according to the Ljung–Box test, which verifies that the forecast errors are not correlated and validates the proposed model.

Growth parameter observed at 30,60,90, and at harvest stage and the following parameters were determined: plant height (cm), number of seeds branches, LAI and reported as dry matter in g plant-1. The seed yield was measured by harvesting net plot area of each plot at crop full maturity (physiological maturity).

Results: The current study showed that the all growth parameter like, Plant height, Dry matter accumulation, number of branches, LAI and stover yield significantly highest recorded with 160 kg ha-1nitrogen and that was at par with 120 kg N ha-1  and with NDR-8510 variety is superior in all growth and yield followed by Vardan and Maya. Highest mustard seed yield recorded with 120 kg N ha-1 and variety NDR-8501. Interaction of nitrogen levels and varieties in case of yield was found significant.

Conclusion: Nitrogen level of 120 kg/ha can be considered as suitable dose for higher yield of mustard. Among mustard varieties, NDR-8501 performed most promising followed by Vardan and Maya in terms of growth and yield and can be recommended for the cultivation in eastern Uttar Pradesh. A combination of mustard variety NDR-8501 along with 120 kg N ha-1 recorded significantly higher growing yield of mustard seed in over rest of the treatments.

Agriculture consumes water in major quantity to fulfill its needs. To conserve and save the water, its careful application with special attention is required, especially in farming. When farming was carried out with modern techniques, it may fulfill this requisite. Today agro-tech products are in good demand and supply, which includes mulch mat, bird net, shade net, sacks, packing, and winnowing, etc, If properly used these technical textiles will improve the quality of farm needs. Natural fibers have better insulation properties under moist condition than polypropylene/ polyethylene. Hence, in the present study, Sisal agro-mats were analyzed against black sheet and control sample to test the water conservation levels in soil with pH 7.1 of the Croton plant (Codiaeum variegatum). Agro-mats were prepared in three thicknesses (1, 2 and 3mm). Sisal 3mm agro-mats conserves soil moisture content to 40-50 percent compared to black sheet and control, which does give spaces to flow air, which dries out the soil. Being economically viable, agro-mats with 2 mm holds comparatively less moisture content are suitable to apply at nursery level where regular watering is needed.

Training is an essential element for appropriate human resource development, which enhances decision making ability of an individual. In India there is a pressing need for efficient human resource development in livestock sector to improve quality of livestock and to increase both quality and quantity of livestock products and, this may be achieved through training of the livestock farmers on scientific animal husbandry practices. The present study was conducted in Jammu district of Jammu and Kashmir state to assess the training needs of livestock owners as perceived by field veterinarians. Ex-post-facto research design and, multistage random sampling plan was followed for the selection of ultimate respondents. Sixty veterinarians working in Jammu district were randomly selected and were given suitably developed questionnaire to document their opinions regarding training-needs of livestock owners. The questions were in six broad groups (breeding, feeding, housing & management, health care, preparation and preservation of livestock products and marketing and finance) and were for evaluation of perceived training- needs in their respective sections. Respondents were asked to rate them in three point continuum i.e. most needed, needed, and least needed with their respective scores of 3, 2 and 1, based on importance of perceived training needs of livestock owners felt by field veterinarians. The summation of scores achieved by the respondents constituted the level of perceived training-needs in each sub-area. Findings of the study revealed that, veterinarians felt “estrous cycle and time of breeding”, “balanced ration feeding and its economical composition”, “care and management of new born/pregnant/productive/sick animals”, “zoonotic diseases and their transmission”, “preparation and preservation of milk and milk products” and “banking & insurance” as  the most  training needed areas of livestock owners.

Trehalose (Tre) a non-reducing disaccharide, formed of two alpha D-glucose molecules, is found in many organisms and is able to protect against a variety of environmental injuries and nutritional limitations. The information regarding its occurrence and role in higher plants is scanty. In the present study, effect of trehalose (@1 mM and 1.5 mM) under heat stress of 35±2°C (moderate) and 40±2°C (severe) for 4 and 8 hours was studied in wheat (Triticum aestivum L.) genotypes viz. HD2967, PBW175, C306, PBW343, PBW621 and PBW590. Membrane thermal stability (MTS) and cell viability were significantly decreased under heat stress of eight hours. Pretreatment with Tre improved MTS and cell viability of selected wheat genotypes under stress and the effect was more pronounced with higher concentration (1.5 mM). Plant growth and vigour were negatively affected by severe heat stress (40±2°C); the reduction was compensated partially by Tre application. Dry matter accumulation and starch content of all studied wheat genotypes decreased under the heat stress, the ameliorative effect was observed with the trehalose application that helped seedlings to sustain growth under heat stress.
