A field study was conducted in the north-western part of Ethiopia to evaluate the effect of urea molasses multi-nutrient block (UMMB) supplementation on productive and reproductive performance and economics of feed supplementation in local Fogera (F) and Holstein Friesian (HF) x F crossbred dairy cows (F 1) during the dry season. The study was conducted simultaneously in a rural subsistence crop-livestock production system using 18 second and third parity Fogera cows and in a market-oriented peri-urban livestock production system using 16 HF x F crossbred dairy cows of similar parity as the Fogera cows. All cows were in their early stage of lactation and the feed types used were the existing dry period farm-specific feeding practices without (control) and with UMMB supplementation (experimental diet). Regardless of the production systems, dairy genotypes showed a significant improvement in daily saleable milk and milk energy off-take, milk quality traits, postpartum ovarian activities, body weight gain, body condition and benefit-cost ratio due to UMMB supplementation. Even though supplementation with UMMB had an overall positive effect on biological as well as economic parameters, the response of cows in the two production systems varied for different traits: crossbred cows showed a particularly strong response in daily milk off-take, improved postpartum oestrus activity and had a greater benefit- cost ratio than Fogera cows in the rural subsistence production system. In general, UMMB was shown to be a viable tool for securing sufficient energy and nutrient intake under on-farm conditions. However, cows with a greater genetic potential will show a higher performance if supplied with sufficient quantities of nutrients and energy than a local genotype. Therefore, under situations of restricted availability of UMMB, first priority in supplementation should be given to crossbred cows over local cows. Source

Hay is the oldest and most important conserved fodder. The aim of haymaking is to store feed for later on-farm use. Traditional haymaking practice in Ethiopia has many problems. Delayed or early harvesting, improper handling system during harvesting, transportation, and storage stages are identified as main causes of feed loss. This project is, therefore, intended to evaluate and demonstrate manual hay presses so as to assist users in haymaking and baling practice. Two hay press models, vertical and horizontal hay presses, were manufactured and after preliminary test, practical on field test was conducted at two sites. Besides, discussions were made with farmers and their opinions were recorded. The test result has shown that, the average pressing rate, bale density, and baling time of vertical hay press was 45.2 kg h-1, 86.5 kg m -3 and 14.1 min per piece. Likewise, similar parameters of the horizontal type were 36.9 kg hr-1, 72.3 kg m -3 and 17.4 min per piece, respectively. It was observed that most of the respondent farmers preferred vertical type press due to its lower energy requirement and better output. Therefore, the vertical hay press model is recommended for further promotion. Source

On-farm survey of farmers' breeding practices, breeding objectives, and selection criteria and on-station feedlot performance evaluation of Washera sheep were undertaken in Ethiopia. The survey revealed that most (79.8%) of the farmers had no breeding ram. The mating system was predominantly uncontrolled. A majority (75.5%) of the sheep owners reported that they herded their sheep flock by mixing with other livestock species mainly with cattle. During grazing, 44.6% of the farmers mix their sheep flock with neighboring sheep flocks. The major sheep production objective was to generate income from the sale of live sheep. Fast growth, appearance, coat color, and pedigree performance were important ram selection criteria, respectively. Ability to breed at early age, pedigree information, mothering ability, and lambing interval were important selection criteria for ewe, respectively. The on-station performance study involved evaluation of feedlot gains and carcass production under five levels of feeding regimes (300, 400, 500, 600, and 700 g day -1 of concentrate feed) for a period of 93 days. The results indicated that the feedlot growth and carcass performance of Washera sheep were very high, with average daily weight gains of up to 126 g and carcass weight of 16 kg, with the optimal level of supplementation for Washera sheep being at 500 g of concentrate per day for a period of 93 days. © 2011 Springer Science+Business Media B.V.

In order to evaluate the socio-economic characteristics of urban and peri-urban dairy production systems in the North western Ethiopian highlands, a field survey was conducted which included 256 farms. It is concluded that urban farmers tend to specialize on dairy production and support the family income from non-agricultural activities, while agricultural activities other than milk production forms an additional source of income in peri-urban farms. The specialization of urban dairy producers includes the more frequent use of crossbred cows with higher milk yield. Urban and peri-urban dairy production contributes to food security of the population and family income of the farmers' families, but also provides a job opportunity for otherwise unemployed people. Access to farm land, level of education and access to certain input services such as training, veterinary and credit services were identified as the major constraints for the future development of the dairy sector. © 2011 Springer Science+Business Media B.V.

An experiment was conducted on station, using a nested design in order to evaluate the effects of a Urea Molasses Multi-Nutrient Block (UMMB) supplementation of typical dry season, roughage based diets on the performance of mid lactating local Fogera and their F1 Holstein Friesian crosses in Ethiopia. Eight cows each from both breeds were assigned to a forage-based control diet and an experimental diet with UMMB supplementation. Highly significant differences were observed between treatments for most production traits. However, Fogera and crossbred dairy cows showed a different response pattern for some traits. Crossbred dairy cows were superior over Fogera for milk production, reproductive performance and benefit-cost ratio regardless of UMMB supplementation. Conversely, Fogera cows had higher milk solid contents and supplementing them with UMMB had a greater effect on milk fat than in crossbred cows. It is concluded that supplementing dairy cows with UMMB during the dry season is basically a helpful measure to maintain production. Depending on the availability of UMMB, priority in supplementation however, should be given to cows with a high genetic potential for milk production. Source
