Effekte einer Ergänzungsfütterung auf autochthone Fogera-Kühe und Kreuzungskühe im nordwestlichen Äthiopien
Abstract
In Ethiopia, there exist an estimated number of 47.57 million cattle of which 11.7 million is found in the Amhara region, north western Ethiopia. The cattle populations consist mainly of local (99%), but also of crossbreds (1%). However, the productivity of cattle is considered to be low. The average daily milk yield of local and crossbred dairy cows can be expected to be 1.5 and 4.3 litres, respectively. The per capita milk consumption is 49% below the African average as opposed to standing first in livestock population in the continent. To respond to the increasing demand for livestock products, various cross-breeding programs started 5 decades ago, but the success rate was rather poor. The reasons for low productivity of livestock are related to feed shortage, health problems, poor genetic potential, and different management factors. Due to high population growth, land is increasingly converted to crop cultivation at the expense of grazing land. Concentrate supplementation is practically impossible for smallholder farmers. Because of these problems, the basal feed source is shifting towards crop residues, which are again with poor nutritional quality. However, a number of sugar factories currently emerge in the Amhara Region. One by-product from sugar processing, molasses will be available for livestock feeding. Based on the experience from other Asian, Central American and African countries, the use of urea molasses multi-nutrient block (UMMB) may be a practicable option for nutrient supplementation during the dry season. In the Amhara region, where the intended research project is to be implemented, most crossbreeding work has been done using Fogera (local) dairy cows as female line and Holstein Friesian as male line. The performance of the local breed and its crossbreds has not been evaluated under different feed supplementation. Therefore, the objectives of this research work are to evaluate the milk yield, milk composition, body weight, body condition, feed intake and reproductive traits of Fogera and crossbred dairy cows with or with-out UMMB supplementation to roughage based diets and to evaluate the cost: benefit ratio of urea molasses multi-nutrient supplementation under on-station and field conditions. This research work will be implemented both on-station and on-farm, using Fogera and crossbred dairy cows. The on-station feeding trial will be conducted at Andassa Livestock Research Center (ALRC) and the on-farm trial will be conducted at Fogera and Bahir Dar Zuria districts, which are adjacent to Lake Tana. UMMB will be used as a supplement to the basal diets. UMMB formulation will be done at ALRC using locally available feed ingredients. A 2 x 2 factorial design will be implemented: 2 dietary treatments (the usual feeding regime as a control vs. supplementation with UMMB) which will be imposed on 8 cows of each genotype (Fogera vs. F1 Fogera x Holstein Friesian). For these experiments, a total of 16 dairy cows of either breed will be used during on-station and on-farm feeding trial, respectively. Before the start of the actual feeding trial, a rapid survey will be conducted in order to have the general picture of the herd structure, the number of dairy cows lactating, all the husbandry systems and product marketing and socio-economics of the area. Laboratory analysis of milk samples before and throughout the experiment and feed samples before the start of the experiment will be done. The feeding trial will last for 5 months; from January 2011 to May 2011 when feed shortage is most critical. Response criteria will be milk yield, milk composition, body weight, feed intake reproductive traits, cost: benefit ratio and body condition of both breeds. Partial budget analysis will be done to evaluate the economic importance of feed supplementation over the control groups.
