Abstract: A study was conducted to evaluate effect of replacing groundnut seed cake with yeast-noug seed cake (BYNSC) mixture on laying performance, egg quality, fertility and hatchability of white leghorn layer chickens. One hundred eighty white leghorn layers at the age of 28 weeks and average initial body weight of 1006±7.18 g (mean ± SD) in a completely randomized design were used. There were 5 treatment rations each with 3 replication and were randomly allotted to 15 pens each with 12...
Abstract: One of the basic agronomic practices to improve the yield potential of chickpea is identification of optimum plant spacing. Thus, field experiment was conducted to assess the effect of inter-row and intra-row spacing on the growth, yield components and yield of chickpea at Chiro District. The treatment consisted of four inter- row (20, 30, 40 and 50 cm) and four intra- row (5, 10,15 and 20 cm) spacing. The experiment was laid out in a randomized complete block design (RCBD) in fact...
Abstract: This study was conducted to assess the characteristics of smallholder dairy production and the Physico-chemical quality of raw cow milk and traditional fermented dairy products produced in Adami Tulu Kombolcha Woreda. A three-stage sampling procedure was used to collect primary data from smallholder dairy producers. In the first stage, from the East Shoa zone, Ademi Tulu Jido Kombolcha were purposively selected due to its high potential in cow milk production as well as marketing. ...
ABSTRACT Velogenic Newcastle disease (VND) has been very much associated with drop in egg production and the production of poor quality eggs. The aim of this project was to study the pathological, biochemical and haematological changes that led to the poor egg production and quality. Two hundred and forty Isa-Brown pullets were purchased from Zartech, Ibadan, Oyo State, Nigeria at day old. They were reared to point of lay. At 16 weeks of age they were divided into two groups of 120 layers eac...
