Thyroid hormones and metabolic rate during induction of Vitamin B12 deficiency in goats
(Taylor and Francis GroupDepartment of Animal Production, University of NairobiDepartment of Animal Physiology, University of Nairobi, 1994)Vitamin B12 deficiency was induced in 15 small East African goats by feeding cobalt deficient Chloris guyana hay (containing 0.02 mg of Co/kg dry matter) over a 25week experimental period. Cobalt was supplemented as an ... -
The performance response of scavenging chickens to nutrient intake from scavengeable resources and from supplementation with energy and protein
(2009)An experiment conducted under farm conditions and management determined the daily supplemental intake, performance and nutrient specifications of scavenging chickens supplemented with energy and protein either alone separately ... -
Mating decision support system using computer neural network model in Kenyan Holstein-Friesian dairy cattle
(Departmeni of Animal Production, 2009)Knowledge discovery in databases (KDD) should provide not only accurate predictions but also comprehensible rules. In this paper, we demonstrate that the machine learning approach of rule extraction from a computer ... -
Milk yield prediction in Kenyan Holstein- Friesian cattle using computer neural networks system
(Departmeni of Animal Production, University of Nairobi, 2009)An essential aspect of understanding any natural system is the ability to acquire knowledge through experience and to adapt to new situations. This study, investigates the use of back-propagation Artificial Neural Networks ... -
he effect of amount of protein in the concentrates on hay intake and rate of passage, diet digestibility and milk production in British Saanen goats
(Department of Animal Physiology, University of Nairobi, 1990)During the first 2 weeks after kidding, 27 multiparous British Saanen goats were offered 1·5 kg hay (98 g crude protein (CP) per kg dry matter (DM)) and from 0·45 increasing to 0·70 kg concentrates (152 g CP per kg DM) ... -
Use of test-day records to predict first lactation 305-day milk yield using artificial neural network in Kenyan Holstein–Friesian dairy cows
(Springer LinkDepartment of Animal Physiology, University of Nairobi, 2010-04)The study is focused on the capability of artificial neural networks (ANNs) to predict next month and first lactation 305-day milk yields (FLMY305) of Kenyan Holstein–Friesian (KHF) dairy cows based on a few available test ... -
Makueni District Profile: Crop Production And Marketing, 1988-1999
(Univesity of NairobiDepartment of Agricultural Economics, 2000)v Abstract This profile describes the changes in policies affecting marketing and crop production in Makueni District since 1988. The creation of the district led to a larger market for milk and vegetables around Wote, ... -
Hay intake, milk production and rumen fermentation in British Saanen goats given concentrates varying widely in protein concentration
(British Society or Animal ScienceDepartment of Animal Physiology, University of Nairobi, 1992)About 8 weeks after parturition six multiparous British Saanen goats with permanent rumen fistulas were allocated to three dietary treatments in a random sequence for three successive 30-day periods. The treatments were ... -
Changes in serum levels of vitamin B12, feed intake, liveweight and hematological parameters in cobalt deficient small east African goats.
(Department of Animal Physiology, University of Nairobi, 1993)Thirty short-horned East African goats were divided into two groups (treatments 1 and 2) consisting of fifteen goats each. All the goats were fed on a cobalt deficient diet containing 0.02 mg Co/kg of dry matter for a ... -
