This paper investigates the factors associated with private sector smallholder livestock and the associated income of the poor in the Indian States of Andhra Pradesh. The data used are drawn from the Livelihood Options Study led by the Overseas Development Institute, London, specifically the Census Survey 2001/2 and Panel Survey of early 2005. Poorer households depend disproportionally on livestock. Important changes were noted; the average size of any single species declined considerably in the five year period beginning from 1996/7, the number of farms keeping the species rose in the 1996/7 to 2001/2 period but dropped in the recent 2001/2 to 2003/4 period. The poorer households kept fewer small ruminants and poultry in the latter period but richer households kept more. This might suggest that the technology is shifting towards what the better off can afford like the intensive poultry keeping, and that they have better access to certain resources such as crop residues. On the other hand, policies such as the ban on grazing by goats will also have affected the poor more since they rely on open-grazing methods. Farmers identified shock/stress variables and natural environment as important for the decrease in livestock population. Livestock act as a very real means of smoothing income by allowing debts to be repaid, farm inputs and medical treatment to be purchased, and dowry to be paid. More than 22% of the farmers mentioned disease problems as a cause of the decline in livestock population. This problem needs to be addressed, possibly through public-private partnership arrangements as are being tried in other countries.

A set of pre-formulated hypotheses about the potentials of inland valleys to agricultural production in general, and livestock (dairy) - based enterprises in particular, were tested with data collected from five regions comprising 71 villages/towns and 630 households in three countries (Nigeria, Mali and Côte d'Ivoire). The study was undertaken to test hypothesis concerning the potentials of the inland valleys systems to agricultural production, and those pertaining to the intensification of livestock production in the valleys systems and their relationships with demand for livestock (dairy) products. Results from the analysis showed that many of the previously held views about inland valley and their potential were supported by the data from the three countries. Most of the hypotheses relating directly with inland valley potentials were accepted in the majority of locations. However, there were few hypotheses which were not supported by data from all countries and study sites. The overall assessment from the surveys is that the potentials of the inland valleys towards dairy production are currently good in all the countries and could be better if the resources available in the inland valley environments (for example crop residues) are better managed and utilized. Intensive use of inland valleys was related more to population density than access to market. Similarly consumption levels of domestic dairy products were influenced by population concentration. Instead access to market influenced positively farmers' practices towards specialization and intensification of dairy production. Increase demand for milk and dairy products is met by intensification and not by increase in herd size. Efforts to ensure continued milking through feeding was not related to herd size. As revenues (sales and home consumption) increased, more lands were left to fallow. These results confirm the assertion that the presence of inland valley systems for cropping and livestock rearing promotes diversification of agriculture, and presumably reduces farmers' production risks.

Four butter-making methods (3 traditional: clay pot - CP, 'mesbekia' - M - a wooden agitator with three to five finger like projections at one end, and a combination of the two - CP+M; and one improved internal wooden agitator fitted to the traditional clay pot - IWA) were evaluated for their efficiencies in terms of fat recovery and churning time at 12 smallholder milk producers in the central highlands of Ethiopia. About 21 litres of milk was needed to produce one kg of butter (83% total solids - TS). An average churning time of 222 min was recorded for the three traditional methods with a mean fat recovery of about 90%. Churning time was significantly reduced by 65% for the IWA as compared to the average of the 3 traditional methods. The effect of holding Ayib (Ethiopian cottage cheese) in whey for different time length (1 h, 2 h and overnight) on Ayib yield was compared. The mean Ayib-making time and temperature was respectively 48 min and 57°C. Weight of Ayib recovered significantly increased with increasing length of time Ayib stayed in whey before separation, amounting to 1266, 1475 and 1776 g per 9.2 litres of buttermilk for 1 h, 2 h and overnight, respectively. About 6 litres of buttermilk was needed to produce one kg of Ayib (20.4% TS). Besides, aerobic mesophylic bacterial count (AMC), counts of enterobacteria, and coliform bacterial count (CC) were performed. Average AMC, counts of enterobacteria and CC of butter samples were 8, 5.3 and 3.8 log cfu/g, respectively, while the counts for Ayib samples were 7.9, 5.1 and 4.4 log cfu/g, respectively. Enterobacter, Escherichia, Klebsiella and Klyuvera were the genera identified, while Enterobacter cloacae, Escherichia coli, Klebsiella oxytoca, Klebsiella pneumoniae and Klebsiella gr. 47 are the species commonly isolated from both products. The knowledge on traditional butter- and Ayib-making efficiencies and their microbial properties is essential to increase yield and improve quality and preservation of the products.

In order to design an effective small ruminant (i.e., goats and sheep) breeding program in Kenya and other areas with similar production circumstances, it is important to understand the socio-economic factors applying to the relevant production system. Information on these was obtained from a questionnaire carried out on both smallholders and pastoral/ extensive farmers in seven selected districts. From the 458 responding households, 18% kept only goats, 34% kept only sheep, and 48% kept both species. Goats were generally ranked lower in popularity. The most represented breeds in the households were the indigenous East African goat and the Red Maasai sheep, and crossbred genotypes of goats and sheep. However, according to the farmers, the pure breeds were more popular than the crossbreeds. The households owned the majority of the used land for small ruminant production. In many cases, male household members were in control of the land. Animals were in most cases owned by the household head only or by both the household head and the spouse. The most important water source for animals was the river with the frequency of watering in the dry season in some cases being as low as once a day. Both males and females made most decisions in smallholder households. Women in the pastoral/ extensive systems participated less significantly in decision making than those in smallholder households, although they were responsible to many animal production related activities.

Sowing area under oil-seed rape (Brassica napus L.) has grown dramatically only during the last 10 years in Latvia. Lack of knowledge and research on different issues is observed. The aim of our research, started on season 2005/2006 in Research and Study farm Vecauce, was to investigate the influence of split fungicide (1st dose of fungicide Juventus 90 s.c. (Metconasol 90 g LE-1) used as growth regulator in autumn at the 4-6 leaf stage and the 2nd dose at the growth stage 63-64) application. Winter rape development in autumn, winterhardiness, disease incidence, and yield and its structure elements were estimated. Totally 13 cultivars were used in the trial, but several assessments were done for 5 cultivars. Additional objective was to evaluate economic effect of fungicide use. Winter rape biometrical indices were influenced by the fungicide application in autumn period and by used cultivar. Fungicide treatment in autumn increased also the rape winterhardiness. Our research for the first time indicated that Phoma stem canker could become a problem for rape growers in Latvia. Fungicide use (in growth stage 63-64) decreased incidence of this disease a little (on average by 5%). Fungicide treatment according to applied scheme increased the average seed yield (check 5.37 t haE-1, with fungicide 5.80 t haE-1; LSD0:05 = 0:18 t haE-1), but impact on yield structure elements was mainly non-essential. Despite agronomic improvements, economic calculation showed that on average fungicide use in 2006 was not pro table. Research should be continued for specification of conclusions.

Effects of nitrogen fertilizers and weather conditions on spring barley (Hordeum vulgare L.) yield and grain quality were investigated at the Rumokai Experimental Station of the Lithuanian Institute of Agriculture in the period of 1998-2000 and 2003-2004. The soil of the experimental site was Hapli Epihypogleyic Luvisol. Analyses were made with fertilisers rates of 0 and 90 kg haE-1. The data of analyses indicated a positive and reliable correlation between the yield of spring barley and the amount of precipitation in May (rate of correlation was 0.70**) and a negative and reliable correlation with the amount of precipitation in June and July (rates of correlation were -0.80** and -0.29* respectively). A reliable though weak correlation was found between the application of nitrogen fertilisers and the yield of grains. The amount of precipitation in April and the spring barley leaf diseases had a considerable negative effect on 1000 grain weight and grain size. Strong correlation was identified between the amount of precipitation in May and June and the protein content in grain. Nitrogen fertilisers promoted protein accumulation in grain.

The vegetation pot experiment was conducted at the Institute of Soil and Plant Sciences of the Faculty of Agriculture of the Latvia University of Agriculture. The aim of the experiment was to investigate the effectiveness of five Rhizobium legumonosarum strains stored in the period from the 18th of August till the 20th of October 2006 in the collection of the Latvia University of Agriculture. Three of the five mentioned Rhizobium legumonosarum strains were included in the international Rhizobium database IBP World Catalogue of Rhizobium collections. Taking into consideration the results of the experiment it has been pointed out that all Rhizobium strains were active and inoculated plants formed nodules on the roots. Inoculation with Rhizobium strains increased the proportion between shoots and roots' weight. It has been found that the dry matter content of the inoculated plants increased in comparison with the untreated ones. In addition, negative correlation between the dry matter and the protein content has been observed.

The aim of this research is to evaluate the variability of the martagonlily (Lilium martagon L.) found in the wild in the west of Latvia. Latvia is situated in a nature zone between the vegetation of Northern and Central Europe. The country distinguishes itself with a large variety of flora and fauna (total approx. 27, 7 thousand species). The genus Lilium L. includes approximately a hundred species, subspecies and varieties of species. In northern Europe, one of the best known and longest cultivated of lilies is L. martagon L. It is distributed across the largest growing area of most species - from western Portugal throughout Europe and Asia. To evaluate the survival potential of L. Martagon L. in Latvia, research was carried out in locations at Kurzeme - districts of Ventspils, Kuldiga, and Tukums. The results indicate that the diversity in genotypes varies according to location and distribution. There are differences in phenotypes and colour variability from pale to bright violet-pink. Diameter of flower varies between of 3.5 to 6.0 cm. The height of these plants varies up to 114 - 130 cm. The flowering time is in June and July. Wild martagonlily found in these regions is growing in calcareous soils among shrubs in river valleys and semi-shaded deciduous forests. This particular martagonlily is hardy and disease resistant and is recommended as a donor in breeding programs.

A study was conducted to determine efficiency of an organic acids and phytogenic additives on pigs' growth processes and digestive tract microflora. The feed of the control group (C) did not contain the additives. The feed of the organic acid group (A) contained 6 kg of organic acids additive per tonne feed for pigs after weaning, 4 kg per tonne feed for grower pigs, and 3 kg per tonne feed for finished pigs. The feed of the phytogenic additive group (F) contained 0.5% of phytogenic additive per tonne feed for pigs after weaning, and 0.2% per tonne feed for grower and finished pigs. The feed of organic acids plus phytogenic additives group (A+F) contained 6 kg of organic acids additive per tonne feed for pigs after weaning, 4 kg per tonne feed for grower pigs, and 3 kg per tonne feed for finished pigs 0.5% of phytogenic additive per tonne feed for pigs after weaning, and 0.2% per tonne feed for grower and finished pigs. Compared to groups pigs from the group (F) had by 9.7%, group (A+F) - by 8.3 % and from group (A) had by 3.2% higher mass. The bests results of feed conversion were found in the group (A+F) - 2.84 kg, which was by 8.5% less than in the group (C), whereas the group (F) had by 5.1% and group (A) - by 6.7% better results than the control group. The results of Duodenum and Rectum microflora analyses showed that use of organic acid and phytogenic additives reduced mould yeast Staphylococcus sp. colony formed units (CFU gE-1).
