Goat production in Ethiopia contributes significantly to national export earnings and the livelihoods of rural households. In the past, a number of research works were conducted to evaluate and improve the performance of indigenous goats. However, systematically compiled information is not available concerning the level of performance of indigenous goats in the country. In this paper, level of performance for major economic traits of indigenous goats is reviewed and discussed. It is apparent from the information presented in this review that the performance of indigenous goat breeds of Ethiopia is highly variable between different management systems. Many of the research reports show that age at first kidding and kidding intervals appear to be shorter in the traditional systems while reproductive efficiency in terms of growth rate, carcass yield, milk yield, litter sizes and survival rate are higher under improved management systems. In terms of body weight and growth rate, lowland goats are not better than those in the other agro-ecologies. Though productivity of indigenous goats is generally considered as low, there is high potential among the indigenous Ethiopian goat breeds under improved management systems. They also produce skins suitable for production of high quality leather products.

Livestock innovation systems and networks: Findings from smallholder dairy farmers in Ethiopia النص الكامل
2012
Asres, A. | Sölkner, Johann | Puskur, Ranjitha | Wurzinger, Maria
This paper uses household and key informant survey data from Ethiopia to: (1) understand the organizational structures that influence change in dairy production systems; (2) explore how local-level innovation system networks are functioning in the smallholder dairy production and (3) identify intervention points for strengthening innovation capacity. Results revealed that public sector actors are the major role players in the dairy production system despite their minor role in marketing linkages. We also found out that the private sector actors play peripheral roles in the network. Differences between innovator and non-innovator social networks were observed, with innovators exhibiting greater access to sources of production knowledge, inputs, credits and markets. Important institutions that could strengthen the stakeholders’ ability to identify, implement and adapt sustainable practices were not included in the processes. We recommend for policy guidance to reform the current agricultural extension system to address institutional and policy issues that constrain effective agricultural innovation system.

This study was conducted in four Peasant Associations in Jamma district. A total of 120 households from four PAs were involved in the study. Ninety eight percent of farmers were supplementing extra feeds and water for their chickens, with the main proportion of food leftover (26.4%) followed by spoiled grain (25.1%). The proportions of households providing supplementary feeding were: 19.8, 21.5, 37.3 and 21.4% in the morning, at noon, afternoon and evening respectively. Most of the households (77.7%) were not giving feeds separately to the flock compositions. Households were practicing of chicken selection with the main characters of egg productivity (35.4) and body weight (38.4%). Majority of households (78%) were using their living room for birds penning at night and women were more (72%) responsible for flock management. The larger eggs with oval shape and smooth in eggshell were the preferred characters in selection of incubating eggs. Farmers (38%) adapted a practice of mixing local eggs with exotic or crossbred eggs while incubating for better hatchability of exotic or crossbred eggs. Around 73% the respondents reported that the highest mortality of chicks was occurring up to 2 weeks of age. But around 12.6% of the households were treating their sick birds with traditional-treatments. Ninety-one per cent of farmers pointed out that more frequently occurring and devastating disease was Newcastle Disease.

Factors affecting growth performance of sheep under village management conditions in the south western part of Ethiopia النص الكامل
2009
Bela, B. | Haile, Aynalem
The study was conducted to assess the growth performance of lambs under village management condition in Jimma, Ethiopia from 1995 to 1997. The overall mean body weight at birth, at weaning (180 days) and up to a year (360 days) was recorded to be 2.45, 18.8 and 25.4 kg, respectively. The overall mean growth rate up to weaning weight (180 days) and up to one year old (360 days) was 92.3 and 68.3 g/day. The non-genetic factors such as season, yea, sex, parity, litter size and district were considered in this study. The main factors had a significant effect (at least p<0.05) on weight for age and weight gains recorded. A consistent significant effect of sex and birth type (single/twin) (p< 0.05) was observed for weight for age and growth rates. The males were heavier than females, by 7.11% and 10.2 % for 180 days and 360 days weight, respectively. The twins were lighter than singles by 20.1 % and 8.32% for 180 days and 300 days weight, respectively. The effect of parity was significant (p<0.05). The lambs born to ewes at first parity had lower weight for ages and weight gains compared to subsequent parities. The lambs born in land scarce area (Dedo district) had lower weight gains than lambs born in Seka (land better area). Differences were significant (P<0.05) and weight gain recorded at 180 days were 85.3 and 90.9 g/day for Dedo and Seka lambs, respectively. The variation in growth performance of sheep in different districts could provide base line information to set a long-term genetic improvement plan by election. The results are discussed in comparison with data obtained from elsewhere in the tropics.

Breed preference and breeding practices for goats in agro-pastoral communities of semi-arid and sub-humid areas in Tanzania النص الكامل

Chenyambuga, S.W. | Lekule, F.P.
A study was carried out to determine farmers’ preferences for goat breeds, desired traits, management and breeding practices in agro-pastoral communities of central and eastern Tanzania. A total of 552 goat keepers from semi-arid and sub-humid areas were involved. Information on goat flock size, breed preferences, breeding practices, traits preferred and husbandry practices was collected using a well structured questionnaire. Out of the 552 household heads, only 21.3% were women. Most of the farmers kept indigenous goats belonging to the Small East African breed and the mean number of goats per household was 8.9 ± 1.0. The majority of the farmers (53.4%) preferred to keep the Small East African goat breed rather than the exotic breeds. The Small East African breed was preferred to exotic breeds because the animals are easier to feed, prolific, tolerant to drought and endemic diseases. Most farmers (70.8%) practiced uncontrolled mating using bucks from either their own flock (66.7%) or neighbours’ flocks (33.3%).Uncontrolled mating was preferred because it is easier to practice (41.2%) and cheaper (41.2%). The buck to doe ratio was 1:3 in semi-arid and 1:2 in sub-humid areas. Breeding males were selected based on body size by the majority (85%) of the goat farmers. It is concluded that livestock keepers in semi-arid and sub-humid areas in Tanzania prefer the Small East Africa goats because the animals are abundantly available and well adapted to the local environmental conditions.

The study was carried out in June 2010 in selected villages of Amhara region of Ethiopia, representing three levels of market quality (high, medium and low), with the general objective of developing a systematic understanding of the links between market opportunities and productivity increases in livestock, with a focus on dairy production. The present report focuses on production aspects of dairy intensification in Amhara region. Findings showed that feeding of concentrates for dairy cattle was more prominent in high market quality sites compared to medium and low market quality sites, which indicated the level of feed intensification as the market quality improved. The contribution of grazing to total diet was higher for indigenous than crossbred cows. Indigenous cows were allowed to graze freely throughout the year and were expected to meet their feed requirement from grazing, especially in the wet and harvest (crop aftermath grazing) seasons, and supplemented during the dry season when the condition of grazing pasture deteriorated. Crossbred cows that demanded better nutrition for better milk production were only allowed to graze for a limited number of hours in a day when grazing pasture was in better condition. They were mostly kept indoors during the dry season to meet their feed requirements through stall feeding. The proportion of crossbred cows exceeded that of indigenous cows in high market quality sites but the reverse applied in medium and low market quality sites. Milk yield data indicated that there is room for increasing average productivity by improving management practices. Due consideration should be given to alleviate the problems in reproductive and milk yield performance to increase productivity and improve dairy-derived income.

The objective of this study was to compare the growth performance of two Nguni ecotypes and its crosses (Nguni x Landim) raised under the same feedlot conditions at the Posto Fomento do Impaputo, in southern Mozambique. Live weight feedlot data, from entry to marketing, were collected every fortnight between 1999 and 2009 from 453 oxen of the Nguni and Landim male ecotypes, as well as the crosses. Year-season of birth had significant effects on live weight at entry in the feedlot and at marketing age. Overall means for average age at entry in the feedlot was 31.8 ± 4 months, with the Landim being younger than the Cross (p=0.07). The average live weight at entry in the feedlot was 390 ± 42.5 kg, with no differences between ecotypes (p>0.05). Males born in dry year-seasons were heavier than males born in wet years-seasons (p<0.0001 to p<0.05).The average age at marketing of the Nguni ecotypes was 34.4 ± 5.08 months, with the Landim being younger (p<0.05) than the Cross. The average live weight at marketing was 446 ± 42.2 kg. The average live weights at entry and at marketing were higher in dry years-seasons than in wet years-seasons. There were no differences between ecotypes for average daily gain (0.89 ± 0.79 kg) in this study. Growth rates for the feedlot in the Nguni cattle obtained in this study were substantially lower than that obtained for the Ngunis in South Africa albeit they entered the feedlot at a much older age. This study demonstrates that in Mozambique feedlot industry is still underdeveloped with main constraints on feed resources, especially concentrates.

he survey was carried out in Horro district of Horro Guduru zone, west part of Ethiopia. The objectives of the survey were: to describe cattle production system, trait preferences, breeding practices, and constraints in utilization of the breed and to use the information generated as baseline data to design breeding strategy of the breed. Data were collected through in-depth interviews, group discussions and secondary data collections from different sources. Statistical Package for Social Science was employed to analyze data. Horro cattle are kept in a mixed crop-livestock production system and are the dominant livestock species in the area. Cattle have multi-functional roles in the production systems. Among reason of keeping cattle, draught power was ranked first followed by milk production. Farmers prefer composite traits from their male and female cattle. Draught power performance, body size, hump size, adaptability and coat color were among the higher ranked preferred traits for male cattle in that order. Preferred traits for female cattle include milk yield, fat yield, calving interval, adaptability and coat color.

Handling, processing and marketing of milk in the North western Ethiopian highlands النص الكامل

In order to describe the ways of handling, processing and marketing of milk in urban and peri-urban production systems of the North western Ethiopian highlands, 256 and 54 dairy farms were selected for survey and monitoring data collection, respectively. Due to poor market access and high transaction costs and the perishable nature of raw milk, the amount of sold milk (products) and prices were significantly lower for peri-urban producers. Prices were also low during fasting periods and during the wet season; when milk production was reactively high. Traditional ways of milk processing at household level include practices which may contain risks for product quality affecting consumers’ health. Providing basic handling and health education for producers therefore is likely to result in improved milk (product) quality on the markets. Direct delivery to the nearby consumers was the largest primary milk outlet for producers of both systems, while retailers and milk cooperatives were the second most common outlets for the urban and the peri-urban system, respectively. Therefore, to enhance dairy production and marketing, milk co-operatives that could be able to market larger volumes and sufficiently reduce transaction costs should be supported by governmental and non-governmental organisations through providing technical and infrastructural support.
