Opis: The socio-economic impacts of COVID-19 on society have yet to be truly revealed; there is no doubt that the pandemic has severely affected the daily lives of most of humanity. It is to be expected that the research activities of scientists could be impacted to varying degrees, but no data exist on how COVID-19 has affected research specifically. Here, we show that the still ongoing COVID-19 pandemic has already diversely and negatively affected bee research at a global level. An online survey disseminated through the global COLOSS honey bee research association showed that every participant (n = 230 from 56 countries) reported an impact on one or more of their activities. Activities that require travelling or the physical presence of people (meetings and conferences, teaching and extension) were affected the most, but also laboratory and field activities, daily operations, supervision and other activities were affected to varying degrees. Since the basic activities are very similar for many research fields, it appears as if our findings for bee research can be extrapolated to other fields. In the light of our data, we recommend that stakeholders such as governments and funding bodies who support research should facilitate the wide implementation of web-based information technology required for efficient online communication for research and education, as well as adequately loosened restriction measures with respect to field and laboratory work. Finally, increased flexibility in administration and extension of research grants and fellowships seem to be needed. It is apparent that adequate responses by all stakeholders are required to limit the impact of COVID-19 and future pandemics on bee science and other research fields.

Growth performance, haematology and serum biochemistry of West African dwarf sheep fed cassava peel-oil palm leaf meal based diets in a hot humid tropics
Peter-Damian Chukwunomso Jiwuba, Lydia Chidimma Jiwuba, Moses Udoha Onyekwere, 2017, izvirni znanstveni članek

Opis: The growth performance, haematological and serum biochemical characteristics of thirty-six West African Dwarf (WAD) sheep of about 10 - 12 months of age and averaged 8.53kg in weight were sourced from the College flock. Four dietary treatments designated as T1, T2, T3 and T4 were formulated to contain 0%, 10%, 20% and 30% oil palm leaf meal (OPLM) respectively were randomly assigned to the animals. The experimental animals were divided into four groups of nine animals each, with each group replicated thrice with three animals per replicate. Each group was allotted to one of the diets in a completely randomized design. The animals were weighed at the beginning of the trial and weekly subsequently and data for growth performance were generated. Blood samples were obtained from one animal in each replicate, and data generated were analyzed statistically. Average daily feed intake, total dry matter intake and average daily weight gain were significantly (P<0.05) influenced by the dietary treatment, with animals on T4 group having higher and better values. Feed conversion ratio (FCR) also differed significantly (P<0.05) with sheep on T3 and T4 (11.82 and 11.49 respectively) having the best FCR. The haematology showed that the packed cell volume (PCV), red blood cell (RBC), and mean cell haemoglobin concentration (MCV) were significantly (P < 0.05) improved at 10%, 20% and 30% inclusion levels of OPLM, respectively. Sheep in treatment groups had improved (P < 0.05) white blood cell (WBC) count than those on the control group. Serum biochemistry results showed that total protein, albumin and globulin were significantly influenced (P < 0.05) and tended to increase with increasing levels of test ingredient. Sheep in treatment groups had higher (P < 0.05) urea values than those on control. Creatinine values at 20% and 30% inclusion differed significantly (P < 0.05) with the control value. Cholesterol was significantly influenced (P < 0.05) and followed an irregular trend across the treatment groups. The results showed that inclusion of OPLM had a beneficial effect on the general performance of the WAD sheep. Therefore, 30% OPLM supplementation was recommended for optimum performance in WAD sheep.

Yield performance and agronomic efficiency in oil pumpkins (Cucurbita pepo L. group Pepo) depending on production systems and varieties
Manfred Jakop, Silva Grobelnik Mlakar, Martina Bavec, Martina Robačer, Tjaša Vukmanič, Urška Lisec, Franc Bavec, 2017, izvirni znanstveni članek

Opis: In 2013 and 2014, a long-term trial (which was established in 2007) was conducted at the University Agricultural Centre in Pivola near Hoče. It included different production systems (conventional, integrated, organic, biodynamic), carried out in a field trial with oil pumpkins. The aim of the research was to analyse the effects of different production systems, varieties (hybrid and population variety) and years of production, on formation of oil pumpkin yields. The agricultural practice has been carried out in accordance with the applicable legislations and standards for the individual production system. When sowing, before fertilizing with nitrogen in early June and after the harvest, the amount of soil mineral nitrogen was monitored. We evaluated the number and weight of harvestable, unripe and decayed fruits, and yield of oil seed pumpkins and calculated the agronomic efficiency of the applied nutrients. The results showed that the year of production, the production system and the variety have a significant effect on some fruit characteristics and the yield of oil pumpkin seeds. The content of soil mineral nitrogen in May and September was significantly influenced by the production system and the year. In June, only the production system had a significant effect. The hybrid significantly increased the yields of oil pumpkin seeds in all production systems, even in the year that was less suitable for production. The agronomic efficiency of the applied nutrients in the biodynamic and organic production system is higher or equal than in the conventional production system, similarly, agronomic efficiency is higher in the hybrid compared to the oldest population variety efficiently. A comparable oil pumpkin yield can be expected in biodynamic and organic production, when proper nutrition and well carried out cultivation practices are combined with a new variety, when compared to less sustainable production systems, which often cause damage to the environment.

Blood profile and gut microbial load of broilers fed siam weed (Chromolaena odorata) leaf meal in their diets
Peter-Damian Chukwunomso Jiwuba, Ifeanyi Princewill Ogbuewu, Elisha Dauda, Caritas Chibuike Azubuike, 2017, izvirni znanstveni članek

Opis: The responses of 96 day old broilers fed Chromolaena odorata leaf meal (COLM) on blood profile and gut microbial load were studied for 49 days. The birds were randomly assigned to four treatment groups and replicated three times in a completely randomized design. The birds were fed four experimental diets formulated at 0%, 2%, 4% and 6% for the starter phase and 0%, 4%, 8% and 12% of COLM at the finisher phase for T1, T2, T3 and T4 respectively. All the haematological parameters were similar (P>0.05) across the treatment groups except MCH and WBC which were significantly (P< 0.05) higher and better in the treatment groups than the control group. The results on serum chemistry showed significant (P<0.05) difference for total protein, albumin, creatinine and cholesterol across the treatment groups. Cholesterol was significantly (P<0.05) reduced with increasing levels of COLM. Results showed that coliforms and E.coli were consistently higher (P<0.05) among the T1 birds than those fed T2, T3 and T4. It was concluded that, COLM enhanced adequate haematocrit and immune status, hypoglycaemic ability, suppresses the growth of gut pathogenic microorganisms and enhanced the growth of beneficial microorganism in broilers.

Combining ability and breeding potential of oilseed rape advanced lines for some of important quantitative traits
Valiollah Rameeh, 2017, izvirni znanstveni članek

Opis: Information on estimates of combining ability of the promising lines of breeding material is important for evolving higher yielding varieties of oilseed rape (Brassica napus L.). An experiment was conducted to quantitatively examine the genetic parameters of phenological traits, plant height, pods on main raceme, pods per plant and seed yield for eight oilseed rape genotypes using a half-diallel crosses. The result of the diallel analysis revealed significant mean squares of general and specific combining abilities (GCA and SCA) for all studied traits, indicating the importance of additive and non-additive genetic effects for these traits. On the other hand estimation of high narrow-sense heritability estimates for days to flowering, duration of flowering and pods on main raceme, indicated the prime importance of additive genetic effects for these traits. L420 and L401 with significant negative GCA effects for days to flowering and days to maturity were suitable for yielding early maturity combinations. L41, Zafar and L22 with significant positive GCA effects for seed yield were superior parents for increasing seed yield. The crosses with significant positive SCA effects for seed yield had at least one parent with significant positive GCA effects for this trait. The crosses including L41×L22, L41×LF2, Zafar×L22 and Zafar×L420 with seed yield of 3421.7, 3400, 3348.1 and 3311.3 kg ha-1 could be promising for determination of superior recombinants for high seed yield coupled with other growth characters in advanced generations of segregation.
