Information from 400 randomly selected female farmers was obtained during the year 1997 to assess the production performance of backyard chicken in Charsadda district, North West Frontier Province (NWFP), Pakistan. Only 16.3% of the farmers were regularly vaccinating their flocks. The majority of the farmers initiated immunization only at the time of disease onset (29.7%) followed by those (28.5%) who did not vaccinate. A high proportion (53.3%) provided no housing, 29.8% provide night shelters and 17% had no housing. Average flock size was 22.0 birds, comprising 8.86 chicks, 2.03 pullets and 11.1 layers. The local Desi chicken dominated the flocks (10.2 birds) followed by Fayumi (6.76), Rhode Island Red (4.20) with White Leghorn least popular (0.83 ). Average mortality in a flock was 23.6%. Mortality was higher in layers (28.1%) than in pullets (18.7%) and chicks (24.2%). Significantly higher losses were found in White Leghorn (35.6%) than in Desi chicken (17.5%). Similarly, higher mortality was found in chicken without housing facilities (26.7%) than in those with access to houses (21.6%). Regular vaccination was associated with higher productivity than vaccination at the onset of disease or no vaccination. Average annual egg production was 76.4 for Desi, 109 for Fayumi, 169 for Rhode Island and 153 for White Leghorn. Mean hatchability was 61.2% with an annual frequency of 4.6 settings and 15.1 eggs set per broody hen. Farmer preference for the "local" Desi chicken reflected their greater capacity to survive and adapt to scavenging management systems. Fayumi and Rhode Island chickens appear to merit further studies as breeds that could improve the productivity of scavenging systems, as they had higher egg production and only slightly higher mortality than Desi chicken.

The purpose of this study was to evaluate the effect of probiotics, herbals and buckwheat bran (Fagopyrum esculentum L.) on growth, profile of blood, gut microbiota, profile of fatty acid in meat and shedding of resistant Escherichia coli (E. coli) in piglets. A total of 44 piglets (Sus scrofa domesticus) from age of day 14 to 56 were divided into 4 groups. Control received basal diet (group C), basal diet + probiotics (group P), basal diet + 3% buckwheat bran (group PB) and basal diet + 1.5% herbals (group H). No effect was observed in growth in all groups. The count of Lactobacillus spp. increased (p is less than 0.05) in jejunum in group P. In the faeces, Enterobacteriaceae decreased in the group P (p is less than 0.05) of 35 days old piglets, but Enterobacteriaceae and E. coli decreased in the group H (p is less than 0.05) of 56 days old piglets. The prevalence of resistance to at least one antibiotic class was 66.7% before and 50% after the experiment in all groups. Multidrug resistance of E. coli was not observed in 14 days old piglets, but was observed in 50% and more in all of study groups of 56 days old piglets. The fatty acid composition of Longissimus thoracis muscle had higher levels of α-linolenic acid and palmitoleic acid (p is less than 0.05), but lower level of stearic acid (p is less than 0.05) in group P. In conclusion, probiotics and herbals improved gut microbiota, fatty acid profile and affected shedding of resistant E. coli, but not growth performance.

Hyperadrenocorticism (excessive adrenal production of sex steroids related to adrenocortical adenomas and carcinomas) is a common disease in neutered male and female pet ferrets (Mustela putorius furo) and causes significant morbidity. Incidence of ferret adrenal disease in Latvia is high because the majority of them are gonadectomized. The most common clinical symptoms include symmetrical alopecia and recurrence of sexual behavior. Sex steroids used to diagnose disease are estradiol, androstenedione and 17α-OH progesterone. It is mentioned that androstenedione is the most sensitive during development of the disease. The aim of this study was to sum up, evaluate and compare clinical findings and blood hormone measurements in ferrets diagnosed with hyperadrenocorticism. Forty two ferrets (n = 20 female, n = 22 male) with various clinical symptoms related to hyperadrenocorticism were included in this research. Clinical examination based on clinical symptom protocol was performed and blood samples were taken in all cases. There is a high correlation between the age of neutering and onset of clinical signs in female ferrets. In both sexes, there is no correlation between clinical signs and levels of sex steroids. In male and female group, symmetrical alopecia, pruritus, scaling and fragility of skin and lethargy are the most common findings. During this research, a ranking system (from 1 to 4) for the severity of alopecia was developed. All ferrets had one or two elevated sex steroid levels. In our research, androstenedione was elevated in 25 cases out of 42. Clinical signs and sex steroid measurements are important in diagnosing hyperadrenocorticism in ferrets.

Legumes are becoming more popular in food and feed consumption. They are promoted by EU policy related to healthy lifestyle and environmental policy. Legumes can be grown in crop rotation as monocrop or in different kind of intercropping systems. It is a well-known fact that legumes play an important role in fixation of the atmospheric N, whereas their influence on other biological and chemical aspects of the soil ecosystem is only explored partially. The experimental trial was established at the Pūre Horticultural Research Centre with the aim of studying the influence of legumes on the soil properties in the intercrop with strawberries (Fragaria × ananassa Duch.). Different genotypes were included in the trial as intercrops: two local broad beans (Vicia faba var. major L.) genotypes, two pea (Pisum sativum L.) cultivars and clover (Trifolium hybridum L.). Two control treatments were included in the trial: with and without nitrogen fertilizer usage. Strawberries were planted in May of 2014 and maintained in the field for three years. Results showed that there were significant differences between treatments in soil respiration rate (SRR) and SRR dynamic throughout the experiment time. Dehydrogenase activity had similar results, though no significant differences between treatments were observed in the third year. No significant difference between treatments was found in the soil organic matter. Obtained data shows that legumes have a significant influence on the soil biological properties but not on biochemical properties. Further research needs to be carried out to determine legume influence on soil environment in more detail.

Environmental conditions and climate change on a global scale affect the overall agriculture and food supply. Edamame, also called vegetable soybean is an import vegetable in the world, especially in the East Asia. China is the world’s centre for vegetable soybean production. Edamame beans are harvested before full maturity when bean pods are green and just before turning to yellow colour. Most cultivated varieties in the world are of Japanese origin. The aim of this literature survey is to give a review on history and consumption facts of edamame, as well as on the yield and quality parameters of this fresh commodity. Monographic method has been used for this review. Edamame has a high nutritional and medical value. Composition of biologically active compounds in edamame plants is dependent on climate conditions, seasonal changes, cultivar properties and maturity stage. Vegetable soybean has a long cultivation history in the world. In Europe edamame is grown, but in Latvia edamame has not been grown until now, but there is some experience in soya grain growing. Pod colour is the main external quality factor of edamame. It can be influenced by light, moisture, fertilization, variety properties, planting density and harvesting procedures. Vegetation period for edamame in most cases is reported to be between 75 and 100 days. Environmental conditions and climate change on a global scale affect the overall agriculture and food supply.

Wheat (Triticum aestivum) is one of the main crops grown in Latvia. Nitrogen fertilizer is one of the most important factors affecting the acquired yield and its quality. The aim of this paper is to describe the nitrogen fertilization impact on winter wheat yield and yield components under two soil tillage systems and after two forecrops. Field trials were carried out at Research and Study farm ‘Peterlauki’ of Latvia University of Agriculture (56° 30.658°C N and 23° 41.580°C E) in 2014/2015 and 2015/2016. Researched factors were (1) crop rotation (continuous wheat and wheat/oilseed rape (Brassica napus ssp. oleifera), (2) soil tillage (traditional soil tillage with mould-board ploughing at a depth of 22 – 24 cm and reduced soil tillage with disc harrowing at a depth below 10 cm), and (3) nitrogen fertilizer rate (N0 or control, N60, N90, N120(90+30), N150(90+60), N180(90+60+30), N210(90+70+50), and N240(120+60+60). Results showed that the nitrogen fertilization significantly increased winter wheat grain yield after both forecrops and in both soil tillage variants. Grain yield significantly increased until the nitrogen fertilizer rate N180. Nitrogen fertilizer significantly affected all tested yield components. Values of yield components increased enhancing N-rate of N150 – N180. The forecrop had a significant impact on wheat yield and 1000 grain weight (both increased when wheat was sown after oilseed rape). Yield and grain number per ear were significantly higher when conventional tillage was used, but number of ears per square m – when the reduced tillage was used.

Milk yield, composition and milk coagulation properties can be affected by kappa-casein (κ-CN) and beta-lactoglobulin (β-LG) genotypes and breed. Latvian Brown (LB) and Latvian Blue (LZ) are local dairy breeds in Latvia. These breeds are not so high-yielding than other commercial dairy breeds, besides, the number of those animals decrease each year. The aim of the research was to analyse the influence of κ-CN, β-LG and breed on milk composition and milk coagulation properties. Data were collected from 56 Latvian Brown and 26 Latvian Blue in 2016. Widespread κ-CN genotype was AA (0.593) in LB breed and AB (0.636) in LZ breed, while β-LG highest frequency was BB genotype. Significant effect was not observed on milk yield; however the highest daily milk yield was from AB κ-CN genotype (19.7 ± 1.52 kg) in LB breed. Significant differences were observed in fat content – the highest fat content accordingly κ-CN was from AA genotype in LB (46.3 ± 1.89 g kgE-1) and 45.5 ± 1.37 g kgE-1 from BB β-LG genotype in LB breed (p is less than 0.05). A lower protein content was observed from AA κ-CN genotype in LZ breed (33.8 ± 1.30 g kgE-1), while highest from BB genotype in both breeds. Curd firmness was not significantly different by genotypes and breed. Significantly shorter milk renneting time of β-LG was obtained from LB breed (14.6 ± 2.76 min, p is less than 0.05), while κ-CN genotype was not significantly affected.

The research was conducted with the aim of studying the possibility of using automatic feeding stations for individual sheep (Ovis aries) feeding. The research was organized in 3 periods, in which 10–13 months old sheep – female only (1st research period), 6–10 months old sheep – female only (2nd research period) and 8–12 months old sheep – female only (3rd research period) were used. Part of the sheep did not visit the feeding station at all. Sequentially, over the research periods the percentage was 13%, 37% and 49%. Upon setting the concentrate daily ration 400 g per sheep, on the average the number of visits to the particular feeding station was 6.1 and 4.7 (sequentially in the 1st and 2nd research period). Upon increasing the concentrate ration amount up to 700 g per day, the average number of feeding station visits was 6.9 (in the 3rd research period). The number of visits to the automatic feeding station was varied (V is greater than 10%). Over the research period live weight of the sheep increased significantly (p ≤ 0.05) for the subgroups of animals which made visits to the feeding station regularly during the entire research period. In all research periods, the average daily concentrate intake (373.5 g in the 1st research period, 333.1 g in the 2nd research period and 581.2 g in the 3rd research period) was 93%, 83% and 83% respectively, of the maximum established feeding standard.

The article deals with the implementation of the LEADER programme in Poland. The aim of the paper was to present the influence of the LEADER programme 2007 – 2013 on rural areas development taking into account its objectives. This topic is current in the context of the Rural Development Programme 2007 – 2013 evaluation and search for effective tools for supporting rural areas. The results of research conducted in 2016 among residents and local action groups are presented. Firstly, the LEADER programme had little impact on the possibility of finding work outside the agriculture. Secondly, the realized projects have contributed to the improvement of the quality of life of the residents in rural areas, especially when it comes to meeting the needs of tourism and leisure. The programme was of great importance in underpinning social capital in the countryside, especially its behavioural and bonding dimension. It is very significant taking into account the low level of social capital in rural areas in Poland. An overall level of activity of rural residents and other entities increased, so as the propensity to engage in joint initiatives and the level of trust. The observed effects of the LEADER programme may in the future contribute significantly to the endogenous development of rural areas.

The aim of the research is to prepare proposals for assurance of the business clusters formation regarding the regional development potential upon study of the clusterization of Lithuanian regional companies. After extensive analysis of scientific literature, the qualification of the cluster, their structure, main features, goals and benefits to its members, region, and sector where cluster is based, are observed. From analysis of relevant secondary data the main problems that hinder the development of clusters in distinct regions of Lithuania are distinguished. It is revealed that clusterization in Lithuanian regions lags far behind big cities, it is much more passive and clusters there often reach only the level of a micro-cluster. Clusters are most developed in the tourism and food industries, using traditional means instead of high-techs, failing to benefit from EU support for clustering development. In order to improve the clusterization situation in Lithuania and its development in the regions, more attention and investment are to be allocated for promoting cooperation between the companies and the business and science, research sectors, and joining the international cluster. The state support should be prioritized in the rural regions locating less clusters, forming a reliable means and communication network for these clusters’ development.
