Calf Rearing

Background: Dairy calves are the future stock of the dairy farms. It is important to describe weaknesses in rearing calves not only to improve their welfare, but also to detect areas where current scientific knowledge is poorly integrated into practice. The aim of the present study was to gather information on calf rearing management practices followed by dairy owners, which are related to welfare. Methods: A survey of calf rearing practices was conducted using a farmer questionnaire to collect data. The survey included 140 family-based small dairy units in seven upazilas of Mymensingh district, Bangladesh. The frequency and percentage of the response were described. Results: We observed that all respondents attended their animals during calving and 82.14% respondents allowed cow to clean the calves immediately after calving. Only 13.57% farmers cleaned the mouth and nose of calf after birth. More than 85.0% owners cleaned and trimmed hooves of the calf after birth. More than 90%% respondents did not cut the naval cord of calf and apply antiseptic. More than half of the owners (54.28%) fed colostrum to calves when the animals were able to stand on their feet and only 37.14% of them fed colostrum within one hour of birth. About 44.28% respondents allowed ad lib quantity of colostrum to calf. It was found that 73.57% of the owners allowed suckling of calf until 3 to 6 month of age. Most of the owners (55.0%) allowed the calves to suckle all the quarter of udder before and after milking. None practiced castration and dehorning for male calves. Majority (97.14%) of farmers did not perform deworming and vaccination schedule of calves. Conclusion: This study identified a number of rearing practices that represent a poor welfare for calf, which may prone towards diseases and hampering the productivity. Therefore, in addition to the traditional practices, scientific knowledge for this aspect is also important to get superior animals for future.

Calf Rearing

Weaning is a stressful step in calf rearing which can lead to oxidative stress. The purpose of the present study was to investigate oxidative stress and antioxidant status in calves pre and post weaning. A total of 22 clinically healthy female Holstein calves at the same age were selected and their blood samples were examined to measure the activity of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) in red blood cells and serum malondialdehyde (MDA) concentration. Sampling was performed in 4 consecutive stages: 7 days pre-weaning, the day of weaning, 24 and 72 hours after it. The results indicated that the activity of SOD and GPx enzymes increased significantly on the weaning day compared to the previous week. CAT activity increased 24 and 72 hours after weaning and its increase was significant 72 hours after weaning compared to the day of weaning. An increase was observed in MDA level on the day of weaning compared to a week before, and the trend was towards increase after the weaning. Weaning stress leads to disturbances of oxidative system balance and causes oxidative damage in calves. This imbalance can be probably resolved by improving the antioxidant system and supplementing antioxidants such as vitamins E and C against free radicals produced during weaning.

The family education responsibilities of rural left-behind children are not fully implemented, and school education is weak, which has caused a series of problems. The education of rural left-behind children has gradually attracted people's attention. In this context, this article studies the current situation and countermeasures of rural LBC education and teaching. This article combines research methods such as questionnaire survey method and on-site interview method for research. In order to better explain the problems of local government, this article first defines the definition of local government, expounds the theory of personality development, and uses scientific sampling methods in the research process to extract research results from some rural areas in our province.了Analysis. Based on the performance of LBC and non-LBC schools, learning guidance and learning, the current situation of LBC education in China was studied. In addition, this article also studied the performance of LBC parents before and after they went abroad, and made some suggestions. The study found that before the parents went out, LBC's academic performance was mainly concentrated at the intermediate level and above, accounting for 78%. After the parents went out, LBC's academic performance decreased significantly, and the results were mainly concentrated in the intermediate and above. Below, accounting for 84%. It can be seen that the role of parents in children's growth education is essential.

Calf Rearing

Management deficiencies on the part of the pastoralists were claimed to be one of the major causes of the high losses of camel (Camelus dromedarius) calves contributing to low productivity of camel herds. In the present study, calf deaths, and the causes thereof, were analysed in connection with pastoral calf management in order to assess possible relationships. Progeny history data on 1506 Rendille, 789 Gabra and 1206 Somali calves born between 1980 and 1995 provided quantitative information on losses and the underlying causes. Assessment of the causes of death, and analysis of related management practices, led to suggestions for management changes. In feedback seminars with pastoralists, however, it became apparent that these management changes would not be adopted because they contradicted the pastoralists' assumptions on the causes of calf mortality. The discussions revealed that differences between pastoralists' and scientists' perceptions determined different opinions on proper calf-rearing management practices. Combining different knowledge systems offers the possibility of a more complete understanding, which is required for the derivation of adoptable calf mortality-reducing interventions that are compatible with the knowledge and production systems of the pastoralists.

Adaptation And Mitigation

<p>Rural areas of the Mediterranean watersheds face great environmental challenges, where climate change impacts the water cycle, the soil, and biodiversity, which are often priority issues for adaptation. These, have been aggravated by historical land management practices trends. In this context, we propose Nature Based Solutions (NBS) in the form of Sustainable Land Management (SLM) actions at the watershed scale to achieve climate change adaptation and mitigation while promoting other ecosystem services.</p><p>SLM actions are local adaptation practices that promote sustainable rural development. Thus, we seek the combination of several actions to achieve regional (watershed scale) more integrated approaches. With this study, we aim at proving that NBS, and thus SLM, is a successful tool for alleviating climate change impacts (i.e. water scarcity, enhanced erosion, biodiversity decline) while promoting the role of land in mitigation and enhancing biodiversity in the rural Mediterranean areas.</p><p>For this, we propose a novel conceptualization of SLM actions that moves from their local application and evaluation to the regional more systemic approaches through their combination. Results show synergies in the atmosphere, biosphere, and hydrosphere, allow for the upscaling of SLM through systemic approaches and point at direct contributions to several Sustainable Development Goals.</p>

Infrastructure plays a key role in society. Recent collapses of bridges have underlined their importance for road functionality, causing disruptions to commuters and emergency vehicles. Major issues arise on rural roads, where the lack of redundancy leads to the isolation of entire communities. Actual approaches to assess the resilience of countryside roads rely on the availability of specific datasets, limiting their practical application; this issue is typically related to traffic data. This research aims to propose innovative algorithms to assess the road network’s vulnerability in rural areas, including a novel traffic data collection process and its calibration. The aggregate metric is called Detour-Impact Index (DII) and compares user costs before and after a disruptive event. The method uses traditional network-impact metrics in combination with a new algorithm that allows us to gather quantitative traffic data starting from qualitative information. User travel time showed good agreement between the proposed procedure and traditional web-based methods. Furthermore, the paper provides user delay costs functions accounting for traffic composition, trip purposes, vehicle operative costs, nonlinear volume–capacity relation, and average daily traffic. A significant aspect is the adaptability of this framework, as it is designed to be coupled with existing approaches. The method is demonstrated on a case study in Tuscany (Italy).

Limited information exists on the effects of forest management practices on bryophytes, despite their importance to forest ecosystems. We examined short-term responses of ground-layer bryophytes to logging disturbance and creation of edges in mature Pseudotsuga forests of western Washington (USA). The abundance and richness of species were measured in four 1-ha forest aggregates (patches of intact forest) and in surrounding logged areas before and after structural retention harvests. One year after treatment, species richness, total cover, and frequency of most moss and liverwort taxa declined within harvest areas. Within forest aggregates, mosses did not show significant edge effects; however, richness and abundance of liverworts declined with proximity to the aggregate edge. Our results suggest that, over short time frames, 1-ha-sized aggregates are sufficient to maintain most common mosses through structural retention harvests but are not large enough to prevent declines or losses of liverworts. Thus, current standards for structural retention, which allow for aggregates as small as 0.2 ha, may be inadequate to retain the diversity and abundance of species found in mature, undisturbed forests.Key words: bryophyte, edge effects, forest borders, forest management, logging effects, structural retention harvest.
