Rezgale-Straidoma, E., University of Latvia, Riga (Latvia) | Rasnaca, L., University of Latvia, Riga (Latvia)
The purpose of this article is to address the quality assurance challenges for local governments in long-term elderly care. The research is based on the qualitative approach. Theoretical approach is based on active aging ideas and quality assurance principles. Authors have started analysis on how to adapt the quality principles of European Quality Framework for Long-Term Care Services in the Latvian elderly long-term care institutions. The experts’ view on evaluation is one of the methods of how to assess the quality principles in long-term care for elderly. The research results show different approaches to quality assurance principles and evaluation at the level of local and central government and the necessity to move towards a unified understanding. Experts emphasised the necessity to discuss quality principles in long-term care institutions and the division of responsibility for elderly care between the local and central government. The main findings are that none of the experts would like to spend the rest of their life, when they reach an old age, in a long-term institution. Principle ranking was successfully used in semi-structured expert interviews. The results show a great extent of variety in evaluating the quality principles of European Quality Framework for Long-Term Care Services in Latvian elderly long-term care institutions.

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.

Flock structure, level of production, and marketing of three Ethiopian goat types kept under different production systems Texte intégral
2014
Tadesse, D. | Urge, Mengistu | Animut, G. | Mekasha, Yoseph
This study was conducted to characterize three Ethiopian indigenous goat types in terms of their composition and dynamics, productivity, and marketing. A set of semi-structured questionnaire was used to collect information from 155 goat owners based on single-visit-interviews. The study indicates that breeding females constituted the largest average flock composition followed by weaners and kids. Goat owners in the study areas relied mainly on births and purchases to build their flock while sales and deaths were the major routes of disposal. Lower commercial offtake (28%) and higher mortality (24%) rates were estimated for all study areas but the figures were lower in pastoral and agro-pastoral systems. On average, female goats in the study area gave first birth at the age of 1.4 years, kidded every 8.6 months and stayed on production/kidding for about 5 years, giving daily milk yield of 0.37 liter. Based on the estimates given by respondents, Somali and highland goats were characterized to have bigger age at first kidding and longer kidding life time, respectively. For other traits such as kidding interval and daily milk yield, no significant performance difference was observed among the goat types. In all study areas, goats were sold mainly at the farm gate when money is needed to buy grains and other farm inputs. Average age at sale/slaughter of male goats was about 1.4 years. Consumers, producers, traders, butchers and brokers were the major buyers of live goats in the study areas. The participation of goat producers in the market was constrained by seasonality of market, low price, and lack of market information and infrastructure.

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.

2011
Belay, Berhanu | Haile, Aynalem
The influence of non-genetic factors on lamb survivability at various ages up to 360 days was studied under village management condition in Jimma, Ethiopia. The overall least squares means of lamb survival rate was 89.0 at 0-60, 81.5 at 0-120 and 50.0 % up to 360 days. The survival rate of lambs up to weaning (120 days) was 81.5 %. Season of birth consistently exerted a significant effect (p<0.05)) on lamb survival. Lambs born during the post rain and dry periods showed a higher survival rate than lambs born during the wet season. Districts showed a significant effect (p<0.05)) on survival rates of lambs. Lambs born in land scarce areas (Dedo) had a low survival rate than lambs born in Seka (land available area). Type of birth did not exert an influence (p>0.05) on lamb survival. Sex had a significant effect (p<0.05) on survivability of lambs at later stages and the females showed higher survivability rate than males. Mortality tended to decrease with an increase with birth weight and decreased as parity increased. The birth weight showed a significant effect (p<0.05) on survival rate of lambs. The lambs with birth weight of 2 kg and above were showing higher survival rate. The lambs with 1.5 kg and lower birth weight showed high mortality rate. The study revealed that, adequate measures to be taken to curb mortality of lambs. The selection of heavier weight and larger litter at birth coupled with improved management could be a means to improve lamb productivity in the villages.

Aquaculture, a sub-component within the fisheries sector is a vital economic activity and livelihood component of rural communities living beside rivers and river floodplains in East Africa. It provides a good alternative source of income and proteins for rural communities. This study aimed to characterize fish production and marketing practices in smallholder farming systems under a national Economic Stimulus Programme (ESP) in the Eastern province of Kenya, and to determine the traits of economic importance to the farmers. Information was collated from 198 farmers, 13 traders and three key informants within Meru District of Eastern Province. The predominant species of fish reared was the Nile Tilapia, followed by the African Catfish and in some instances a combination of the two species were reared under polyculture. Good growth rate and survival of fish were noted to be the most important traits of economic importance to the farmers. Fish produced was mainly sold to the local community and within local markets. Traders, however, indicated that the demand for fish was much higher than the supply, hence also sourced fish from Lake Victoria in Nyanza for sale. It was also indicated that the taste of fish differed greatly depending on the source, with wild fish strains from Lake Victoria having a “sweeter” taste than the farmed strains. Strains of fish selected for improved growth and reproduction were not available for aquaculture. Feeds and feeding management of farmed fish was also a challenge. It was evident that there is a great need for supportive research on environmental impacts, productivity and quality of fish reared, and marketing of fish products within the riverine environments of Kenya. Key words: aquaculture, fish marketing, traits of economic importance

2003
Ncube, M. | Dzama, K. | Chimonyo, M. | Kanengoni, A. | Hamudikuwanda, H.
The effect of boar genotype on the reproductive performance of local sows was investigated. Large White (LW) and local Mukota boars were mated to 20 sows over 3 parities and the performance of the sows and litters were compared up to weaning. Data on the gestation length, number of piglets born alive (NBA), the number of piglets born dead (NBD), number weaned and the sex ratio were recorded. The weights of the piglets were recorded within 16 hours of birth and also at weaning. No creep feeding of the piglets was done and weaning was done at 35 days of age. There were no differences in the number of services per conception and the NBD. Litter size at birth, NBA and the number of piglets that were weaned were higher in sows mated to LW boars than to indigenous boars. These findings indicate that imported boars can be used under smallholder pig production systems as they complement traits of both the local and imported breeds.

Fire is a major disturbance in hemiboreal forests; it affects not only trees, but also ground vegetation. Previous studies have analysed the succession of ground vegetation after the fire, but not addressed the impact of the size of the burned area on revegetation of it. Therefore, the aim of our study was to assess the differences in post-fire ground vegetation in relation to the distance from the edge of the affected area. Vegetation data were collected using Braun-Blanquet method in three sites (122 sample plots) affected by forest fire and five clearcuts (not affected by fire) (92 plots), all regenerated by Scots pine 6 – 7 years before the assessment. The number of ground vegetation species (in all sites predominantly birds or wind dispersed) as well as their projective cover was not affected by the distance from the nearest edge of burned or clearcut, except in burned sites on dry sand soil (Vaccinosa and Myrtillosa), where herbaceous plant and shrub cover was decreasing (from 23.5% to 11.6%) and bryophyte and lichen cover – increasing (from 3% to 13.9%) with an increasing distance from the edge of the area. The total number of plants in burned areas was twice smaller than in clearcut in the same soil conditions but such large difference in projective cover was not observed. There were no significant differences between burned and clearcut areas in respect to Ellenberg’s indicator values on both soil types, as well as no trend in Ellenberg’s values for soil moisture in relation to distance from the nearest stand edge.

Polmanis, K., Latvian State Forest Research Inst. Silava, Salaspils (Latvia);Latvia Univ. of Agriculture, Jelgava (Latvia) | Klavina, D., Latvian State Forest Research Inst.

The impact of climatic and genetic factors on needle cast damage, as well as relationship between the degree of damage and survival and growth of trees was evaluated in the study. The analysis was done in two series of experiments, both established in two locations in Latvia (central and eastern part). Needle cast damage (in 5 grade scale) as well as the height and height increment, diameter of root collar and survival of trees were assessed. Results suggest that the degree of needle cast damage was influenced by the genetic, as well as climatic factors, and also their interaction. The average degree of needle cast damage in experiment of open-pollinated families was 4.7 ± 0.01 in central and 4.6 ± 0.03 in eastern Latvia; in the experiment of control-crossed families it was 4.6 ± 0.02 in central and 3.4 ± 0.04 in eastern Latvia. The impact of genetics on the needle cast damage degree was statistically significant (p is less than 0.05), and this effect was observed when any of growth traits (diameter, height or height increment) was used as a covariate in analysis. Results suggest the potential to select more resistant families, since the genetic correlation of grade of the damage between locations was significant (r = 0.40 - 0.72) and therefore improve also the growth of trees, since the grade of the damage had a negative correlation with growth traits both at provenance and family mean level (r = -0.69 and r = -0.42; p is less than 0.01).
