Item Effect of Bovine Somatotropin on Milk Yield of a Cross Breed Herd in Central Kenya(1991) Abate, A.N.; Mwangi, D.M.; Gucugia, S.; Mbugua, N.Twenty four dairy cross breeds were used to study the effect of sometribove (500 mg) administered as a long release formulation of bovine somatotropin (BST) on milk production. The BST was administered at 14-day intervals by subcutaneous injections in the ischio-rectal fossa area. BST, significantly (pItem Kari Narp 11 Project Preparation Report 1995(Kenya Agricultural Research Institute, 1995) Abate, A.N.; Cheruiyot, H.K.; Kimani, L.W.; Kiome, R.M.; Hinga, G.; Madumadu, G.G.; Mailu, A.M.; Matata, J.B.W.; Mbabu, A. ; Muchena, F.N.; Mulandi, J.C.; Mulandi, J.C.; Ngundo, B.W.; Wandera, J.K.; Oketch, A.G.O.; Kamau, C.R.; Kenya Agricultural Research Institute; ODA; Rockfeller Foundation; World Bank; Royal Netherlands Embassy; USAIDAlthough most sectors of Kenya's economy have developed considerably over the last fewd ecades, the agricultural sector still remains the mainstay of Kenya's economy. Kenya still relies heavily on the agricultural sector- for generation of income, employment, foreign exchange earnings and the provision of raw materials for the industrial sector. The priority of Kenya's agricultural policy is to achieve internal self sufficiency in food supply, to maintain adequate levels of strategic food reserves and to generate a surplus of .crop and livestock produce for export. In 1990 the sector accounted for 28.2% of Gross Domestic Product (GDP). It employs over 70% of the rural workforce and generates about 64% of export earnings. Between 1985 and 1990 agriculture grew at an average rate of 4.1 % per annum but stagnated at 2% in 1992 and 1993 (GoK, 1994). Given major constraints posed by rapid human population increases and scarcity of arable land, accelerated agricultural growth can only be achieved by increasing the productivity of the fixed land base. The growth requires development of production incentives, services and institutions needed to encourage innovation and investment.Item Nutritive Value Of Maize Forage Silage Fed To Dairy ows For An Intergrated System of Grain And Milk Production In Kenya(Augusta Njoki A, 1990) Abate, A.N.The study reported in this thesis was designed to assess whether the maize crop could be used as a source of forage for dairy cows as well as a source of food for human consumption. It was carried out between 1986 and 1989 and consisted of three experiments. The first experiment was designed to determine the quantity and composition of forage DM that was obtained by harvesting maize plants above the cob at different stages of growth. The results of this experiment were used to determine an optimum time for harvesting forage for subsequent feeding trials. Experiment II was aimed to examine the effect on the milk yield of dairy cows fed on maize forage silages harvested at two stages of maturity together with two levels of concentrate. The third experiment was designed to study the effect of supplementing early and late cut silages with either dairy concentrate or cottonseed cake on the DM intake and milk yield of dairy cows.Item Substitution Of Finger Millet (Eleusine Coracana) And Bulrush Millet (Pennisetum Typhoides) For Maize In(1983/1984) Abate, A.N.; Gomez, M.The first experiment was conducted to determine acceptability levels and growth performance when bulrush millet or finger millet was substituted for maize at 0, 20, 40 or 60% in both broiler starter and finisher feeds. The chicks fed on the bulrush millet diets had the highest overall body weight gain of 1649 g per chick at 55 days. Performance on the finger millet diets was comparable to that on maize. In view of the higher protein content in the bulrush millet tested, subsequent experiments were conducted to determine the value of using bulrush millet not only as an energy source, but also as a part substitute for protein supplements in broiler diets. The bulrush millet included at 70% was shown to effectively replace part of the vegetable protein supplement provided the diet was supplemented with up to 0.3% lysine.Item Substitution of Finger Millet (Eleusine Coracana) and bulrush Millet (Pennisetum Typhoides) For Maize In Broiler Feeds(1983/1984) Gomez, M.; Abate, A.N.The first experiment was conducted to determine acceptability levels and growth performance when bulrush millet or finger millet was substituted for maize at 0, 20, 40 or 60% in both broiler starter and finisher feeds. The chicks fed on the bulrush millet diets had the highest overall body weight gain of 1649 g per chick at 55 days. Performance on the finger millet diets was comparable to that on maize. In view of the higher protein content in the bulrush millet tested, subsequent experiments were conducted to determine the value of using bulrush millet not only as an energy source, but also as a part substitute for protein supplements in broiler diets. The bulrush millet included at 70% was shown to effectively replace part of the vegetable protein supplement provided the diet was supplemented with up to 0.3% lysine.Item Wet Season Nutrient Supply to Lactating Grade Animals Managed Under Different Production Systems(1991) Abate, A.; Abate, A.N.Small holders are the largest producers of milk in Kenya accounting for about 80% of the annual marketed value (Abate et aI., 1987). One of the main features of small holder dairying is the use of animals of high genetic potential capable of Producing at levels higher than what is normally reported. Production rarely matches genetic capability mainly because of inadequate nutrition (Wachira, 1982). It is possible to improve present output levels through rationalized feeding programmes based on knowledge of nutrient supply .and intake. This paper aims to report on the quality and consumption of different types of feeds fed during the long wet season to lactating animals on farms practicing zero--, semi zero-and grazing systems of production.
