Increasing competition among health care service providers for pets and constantly growing requirements for the veterinary service quality, force veterinary service providers to search for some possibilities to remain competitive in the market in order to meet both customer needs and expectations, and animal needs best. The aim of the research is – having identified the choice motives for animal health care service, to enumerate the factors, influencing the choice of veterinary service. In order to find the pet keepers’ approach concerning the factors, influencing the choice of veterinary service, a pilot research was completed. According to the gained primary data results in the research, it was found that the key factors, influencing the choice of veterinary service are as follows: the service quality of health care, the recommendation of the person responsible for animal care and the price for the delivered service.

The evaluation of EU Member States’ co-founded programmes was assigned particular importance in recent years. The core question to be answered in programme evaluation is whether the stated objectives are accomplished by particular intervention. Until recently, the use of ‘naïve’ estimates was common in the evaluations of EU Member States Rural Development Programmes. The use of these estimates leads to potentially substantial selection bias resulting from using the outcomes of non-participants as a proxy for the possible outcomes of participants in the case of non-participation. The effectiveness of interventions on outcomes of interest can be better evaluated by propensity score matching (PSM). The objective of the study is to determine the net average effects from semi-subsistence farm support measure of the Latvian Rural Development Programme 2007 – 2013. To reach the research objective, propensity scores based on the most important characteristics were calculated for participants and non-participants of the measure and average treatment effects for gross value added were evaluated by matching methods. The research results show that the positive programme effects evaluated by ‘naïve’ estimators are overestimated in comparison with the results obtained by more rigorous PSM method.

Staniuliene, S., Vytautas Magnus Univ., Kaunas (Lithuania) | Januleviciene, L., Vytautas Magnus Univ., Kaunas (Lithuania)
Considering the deficiencies of social services for the elderly in governmental institutions and growing demand of ensuring services in rural areas, the paper aims to assess the needs of elderly people for social services in the selected rural areas and to propose the social services’ development opportunities in terms of domestic help for the elderly. The social services facilitate support to elderly dependents in their homes, without interrupting their relationships with the family and the community, and improving their quality of life. The survey has shown that the municipality usually satisfies only basic biological needs of old people in rural areas. In order to ensure the well-being of elderly people, a complete cooperation among governmental and non-governmental institutions is required. Development of the services should be focused on the provision of the domestic help services for elderly people who do not receive them, and the diversity of the services for those residents who receive services from the municipality. The implementation of the development project of the domestic help services would enable the elderly residents of the rural municipality to have access to the most necessary services at the required frequency and intensity, considering the recipients’ needs, thus improving the quality of life of the elderly people of local community and ensuring their dignified ageing.

Nowadays the need for a qualitative, accessible and varied lifelong learning is becoming more and more necessary. In Latvia, different institutions take part in the implementation of lifelong learning; however, in spite of the negative factors of demography and migration, changes of work force supply and demand, investment and information shortage, the role of universities has not been properly investigated. The role of higher education in lifelong learning was studied in 9 state universities of Latvia in the period of 2013 – 2015. Monographic analysis and method of synthesis, data statistical research methods – grouping, comparison, relative and average indicators, as well as dynamics line analysis was used in the article. The study proved that the number of occupied work places has increased in 2015. However, it has not reached the average of ten and seven years since 2006 and 2009. Comparing with the free vacancies, the number of them has increased by 2164, especially in the profession group specialists and senior specialists, which as well as executives, is the target audience of universities, which in its turn is a lifelong learning event insufficiently used potential. The universities have suffered because of demographic and migration factors: the rate of student number increases (-9.4%). In order to reach the goals of education politics, universities try to direct education function from studies to lifelong learning; they try to improve existing lifelong learning courses and programs, as well as to propose new ones in order to offer something for workforce corrections.

Nowadays, when the general rate of unemployment in Latvia is not that high anymore, there are still a lot of people who are unemployed for many years and during all those years they are abusing the budget of municipality by receiving social benefits. The aim of the article was to examine the way how the long-term unemployed social benefit receivers assess the meaning of support in job searching. On the basis of The Theory of Planned Behaviour a questionnaire was developed by the authors, 37 long-term unemployed social benefit receivers registered in Riga Social Service were asked to take part in the survey and gave informed consent. The results show that the respondents who are longer unemployed receive more support from their families. Statistically significant correlations (p=0.03) were found between the duration of unemployment and person’s determination to search a job, the unemployed who are longer without a job are less active in job searching process. Direct support in the job searching process is deeply connected with the possibility to share individual’s thoughts and emotions with the family. There is no statistically significant correlation between men and women responses.

Selection efficiency for growth performance of Menz sheep in a community-based breeding program Полный текст
2020
Abebe, A. | Banarjee, S. | Goshmie, S. | Bisrat, A. | Besufikad, S. | Zewdie, T. | Gizaw, Solomon
The study was undertaken to evaluate the efficiency of selection on growth performance of Menz sheep under a community-based breeding program (CBBP) from the period of 2009 – 2017. A total of 3996 lamb records (ram lambs 2025/ ewe lambs 1971) were used to evaluate the phenotypic and genetic factors affecting the growth traits of Menz sheep. REML in Wombat and General linear model on SAS (version 9.0) were used to evaluate selection efficiency for growth of Menz sheep. The least squares means and standard errors on phenotypic growth weight for birth, weaning age, six month age and yearling age were 2.58±0.004, 8.99±0.02, 13.28±0.02 and 19.94±0.06 kg, respectively. The effect of sex was significant (p<0.001) only for birth weight and no significance effect (p>0.05) was observed for weaning, six month and yearling weights. All growth traits were not affected by fixed effect of parity and birth type in this particular study. However, birth season and birth year had a great influence (p<0.0001) on all growth traits. The genetic trend on estimated breeding values (EBV) was not consistent across years and varied between sexes. The highest EBV for weaning, six month and yearling were recorded for the year 2013 and the lowest in 2009 (at weaning and six month) and 2015 (at yearling).The female EBV (at weaning, six month and yearling) was higher than male for the current (2017) and base population (2009).The responses to selection as compared to base population (2009) for birth, weaning, six month and yearling weight were – 0.00446Kg, + 0.11Kg, + 0.54Kg and + 0.75Kg respectively. This study indicates that improvement in body weight for Menz sheep through CBBP is possible; however, the response to selection varied across years and its pattern was irregular for the implemented years due to the problem on selection of breeding rams (lower availability of breeding rams) and management effect.

The objective of this study was to estimate genetic parameters of reproduction traits of pure Fogera cattle at Metekel Ranch. Metekel cattle Breeding and Improvement Ranch has so far been engaged in maintenance of Fogera cattle population outside their adapted environment (ex-situ conservation). The breeding program has two components: selection and crossbreeding. The establishment of the pure breed unit is meant for the improvement of the Fogera breed and for providing heifers to cross- breed to exotic dairy sires (by Artificial insemination). In cross breeding program; crossbred animals are produced through artificial insemination of Fogera cows with Friesian semen. Around three to six months of pregnancy, the F1 cross heifers are sold to farmers for milk production (Melaku et al., 2011a, b). Very recently the ranch started to distribute non pregnant F1 cross heifers. WOMBAT software was used to estimate genetic parameters. The variance components and heritability were estimated using a Uni-variate animal model using four models which fitted direct additive, dam genetic and permanent environmental effect as a random effect and the fixed effects (year, season, sex and parity). Parameter of age at first calving (AFC) were estimated using Model 1 (Y= Xb + Z1a + e), Model2 (Y= Xb + Z1a + Z3c + e), Model3 (Y= Xb + Z1a + Z2m + e (cova, m = 0), and Model4 (Y= Xb + Z1a + Z2m + Z3c + e (cova, m = 0) whereas parameters of reproductive traits including gestation length (GL), calving interval (CI) and days open (DO) were estimated using model 2 and 4 which fit permanent environmental effect due to repeated records per cow. Correlations (genetic and phenotypic) among the different traits were estimated from bi--variate analysis by using model 1 for growth traits and AFC and model 2 to estimate the correlation between CI, GL and DO and birth weight (BWT) and GL. Correlation between birth weight and gestation length were estimated by treating gestation length as a trait of calf. Due to record limitation correlation between AFC with other reproductive traits were not estimated. Estimates of direct heritability of reproductive performance traits from the best model were 0.003 ± 0.05 for AFC, 0.00 ± 0.03 for GL and CI and 0.013 ± 0.03 for DO. The phenotypic correlations between reproductive traits were 0.003 ± 0.034 for CI and GL, 0.37 ± 0.041 for CI and DO and 0.167 ± 0.036 for DO and GL and the genetic correlation between reproductive traits ranged from -0.94 ± 0.2 for DO and GL to 0.83 ± 0.579 for CI and DO. Genetic correlation between growth and AFC ranged from 0.77 ± 0.24 for BWT and AFC to 0.87 ± 0.03 for pre-weaning average daily gain (PADG) and AFC. The phenotypic and genetic correlations between BWT and GL were 0.03 ± 0.05 and -0.84 ± 0.013 respectively. The results of genetic correlation between considered traits was ranged from moderate to high and it indicates that selection for one trait would have a significant effect on the other traits not considered however selection must be done with caution. The heritability estimates confirmed the presence of high environmental effect among the study population and it masks the individual animal genetic difference. Given the low heritability estimates obtained, effective improvement in reproduction performance of Fogera cattle could be achieved by improving the production conditions and through crossbreeding.

A study to develop body weight prediction equations based on various body measurements was conducted in rural Kamuli district, Uganda. Body weight (kg) and body measurement data (cm) were collected from 411 pigs between 15 and 127 kg from both local and exotic (mainly crossbreds) pigs. Five body measurements; body length, heart girth, height, body width and flank-to-flank were taken from each pig. Prediction models were developed by regressing weight on pig body measurements. The models were developed for pigs categorized as < 40kg, ≥ 40 kg and an overall single prediction model. Mean weights of < 40 kg and ≥ 40 kg were 27 ± 6.5 kg and 63 ± 19.6 kg, respectively. Body length and heart girth were used to predict (R2 = 0.89) weight for the < 40 kg pigs with the prediction equation; Weight = -41.814 + 0.296 (body length) + 0.654 (heart girth). Four body measurements; body length, heart girth, height and body width were strongly predictive (R2 = 0.92) of live body weight for the ≥ 40 kg pigs with the prediction equation; Weight = -108.198 + 0.228 (body length) + 1.094 (heart girth) + 0.267 (height) + 0.922 (body width). The flank-to-flank measurement did not affect model prediction (p > 0.05) and quadratic terms also did not improve accuracy and were not included in any prediction models. These results suggest that live weight could be accurately estimated using two or more pig body measurements. It was concluded that this weight estimation tool would empower Ugandan small scale pig farmers by providing them with an accurate estimate for the animal’s live weight and giving them better bargaining power when selling their pigs.

2008
Holmann, Federico J. | Tiemann, Tassilo T.
Objectives of this study were to compare costs and expected benefits of feed supplementation in cattle with alternative shrub legumes during the dry season using as a case study the hillsides of Central Nicaragua. The information used was gathered in a survey of 32 farms in the states of Boaco and Chontales in Central Nicaragua. The survey was designed to determine herd structure, land use patterns, milk and beef production, and use of inputs for animal nutrition, in order to estimate production, reproductive parameters and employment of family/contracted labor, as well as indicators of profitability of the alternatives under study. To calculate the economic return to the investment in alternative forages, a simulation model that applies optimization techniques through linear programming, implemented as a spreadsheet, was used to perform an ex ante evaluation of the costs and benefits of different land use alternatives and of interactions between technological components and biological productivity. The model compares the costs and benefits of the traditional feeding system versus an improved feeding system. The traditional system consists of grazing naturalized pastures (Hyparrhenia rufa) during the rainy season. In the dry season producers supplement the herd with small areas of king grass (Pennisetum spp.). The improved feeding system consists of establishing forage legumes for dry season feeding as a supplement to replace king grass during the dry season. Supplements to evaluate are the shrub legume Calliandra calothyrsus as partial replacement of the herbaceous high quality legume Vigna unguiculata, commonly known as Cowpea. Under the new feeding system, herd size can be increased by 60% due in part to the increase in stocking rate as well as to the increase in the quality of the diet offered with higher protein content. This increase in herd size raises both milk and beef output that generates an increase in farm income by 1.8 times more (i.e., from $1,314/farm/yr to $2,386). The economic return to family labor is increased by 20% to $ 5.26/day equivalent to 2.3 times higher than the local wage rate. The adoption of Vigna (Cowpea) after the harvest of maize/beans and a shrub legume as Calliandra to replace king grass seem to have the potential to significantly improve the productivity in smallholder farms. with the resulting increase in the economic return to family labor.
