Do Firms Have Preferences In Hiring By Gender? Evidence From Kenya, Richard Agesa
Do Firms Have Preferences In Hiring By Gender? Evidence From Kenya, Richard Agesa
Journal of African Policy Studies
While issues of employment segregation by gender have been extensively studied in developed countries of the West, few such studies have been conducted in the developing economies of Africa. This paper fills this gap by examining gender imbalances in hiring decisions by firms in non identical industries using the most recent data from Kenya. The findings suggest that women are more likely to find employment in agricultural based industries and in industries with tasks that require human contact. In contrast, men tend to be hired in industries that not only perform physically demanding tasks, but also require continued work experience.

Aunty Annie Milgin describes herself as being born under a tree in the scrub near the former Paradise Station on Nyikina Country. She acknowledges knowledge came from her Grandfather and other old people. Importantly she recognises her Father and Mother, and her Grannies (grandchildren), as teaching her to understand both the ‘old ways and the new ways’. She talks to how the old people taught her many many things, and she describes these Elders as having as’ we call them our PhDs’. Aunty Annie was ‘taught from a young age out on Country’, through her lived experiences all the different …

Changes In Elephantgrass Plant Components With Maturity: 1. Percentage Dry Yield, P Mislevy, F G. Martin, M B. Adjei
IGC Proceedings (1977-2023)
Elephantgrass (Pennisetum purpureum Schum.) biomass can be a source of energy for tropical regions of the world because of its high dry matter production (Mislevy et al., 1986 ; Prine et al., 1987). Research has shown the production of energy (methane) from biomass can be best understood through systems analysis methodology that integrates the availability of land, climate, production inputs, plant quality, etc. To assess available technology and identify information gaps Biomass to Methane (Biomet) models have been developed to determine the impacts of basic growth processes in response to the crops environment (Mishoe et al., 1987). Biomass growth …

The population of Indonesia is over 145 million and more than 56 % of them earn their living from agriculture (Bi. Stat. Ind., 1983). A major problem in the development of improved animal production has been the shortage of feed and the generally low nutritive value of tropical forages which limit livestock production in Indonesia (Asian Agriculture Survey, 1969). The production of feed of adequate quality for ruminants is an important consideration particularly for small holders. In many situations, nitrogen fixing legume trees can be used as a high protein feed supplement which improves the utilization of grasses and crop …

II existe tres peu de donnees concernant la valeur nutritive des arbustes fourragers ; les rares etudes realisees en Tunisie ont porte surtout sur leur productivite, la charge animale et sur leur appetence (Hamrouni et Sarson, 1975; Ben Boubaker, 1985). L'objectif de ce travail est d'etudier la valeur nutritive des feuilles et brindilles d' Acacia cyanophylla, d' A triplex nummularia et de Medicago arborea ainsi que leur contribution dans la ration de caprins et d'ovins.
Utilization Of Native Mediterranean Fodder Trees By Dairy Goats, M Meuret
Utilization Of Native Mediterranean Fodder Trees By Dairy Goats, M Meuret
IGC Proceedings (1977-2023)
Few data are available on utilization of fodder trees and shrubs by lactating goats. In most cases, predictions of animal performances on the basis of recommendations obtained from standard reference trials, do not correspond with production results achieved on the farm. Using measurements in digestibility cages and on rangelands (chromic oxide marker), we recorded intake, apparent digestibility of diets and performances of goats well used to rangelands and browsing fresh oak foliage (Quercus ilex and Quercus pubescens).

Phenols As Defensive Compounds In Birch (Betula Spp.) Metabolism Of Platyphylloside In Goats, Rabbits And Hares, R T. Palo, G Iason, P G. Knutsonn
IGC Proceedings (1977-2023)
Herbivores of the boreal forest like moose (Alces alces), hares (Lepus spp.) and birds (Tetranoidae) use birch as a major feed source. The tree is of medium preference to the animals and is low in available nutrients for most of the year. Apart from a high amount of lignified cell walls it also contains considerable amounts oflow molecular phenolic substances (Palo, 1984). A herbivore feeding on birch could thus be excepted to ingest large amounts of phenols. These are in general enough fat soluble to enter animal cells expected to ingest large amounts of …

Forage Production And Nutritive Value Of Leucanea Leucoephala In Southern Puerto Rico, L E. Tergas, R Milton Martinez, A V. Mendez Cruz
IGC Proceedings (1977-2023)
Leucaena leucocephala (L.) is a perennial schrub native to Mexico, Central America and the Caribbean, considered by investigators as a valuable forage legume because of its capacity for high production of digestible forage with a high protein content and tolerance to drought in semiarid regions with annual rainfall less than 1,000 mm (Skerman, 1977). The soil fertility of the semiarid region in southern Puerto Rico is adequate, but rainfall distribution is limiting for forage production and nutritive value. There is a demand for a suitable and inexpensive source of high quality forage to improve the diet of the grazing cattle …

Effect Of Chemical Composition Of Roughages On Their Degradation Characteristics In The Rumen And Their Relationship With The < In Vitro > Organic Matter Digestibility, S Lopez, Dolores Carro, J S. Gonzales, Conchita Carpintero
IGC Proceedings (1977-2023)
The microbial fermentation of feeds in the reticulo-rumen allows ruminants the utilization of feeds with amounts of cell wall components, i.e. roughages. This rumen fermentation can be affected by the feed chemical composition and numerous techniques have been developed for its determination (Van Soest, 1982). The objective of the present work is to investigate the effect of the chemical composition of forages preserved under different methods on their degradation characteristics in the rumen determined by the « in sacco » method and to study the relationships between the « in vitro» organic matter digestibility (IVOMD) and the rumen degradability.

Rumen Degradation Of Various Grass Species At Different Stages Of Growth, L J. Halliday
IGC Proceedings (1977-2023)
The species and cultivars sown depends on the farming system practiced. These developing swards are however, always invaded by native species including Agrostis, Paa and Festuca spp. which are generally referred to as 'weed' grasses. While the merits of Lolium spp. are well documented (Minson et al. 1960; Norton, 1982) information on the weed grasses is limited (Haggar, 1976). The potential for milk and meat production is dependent on the supply of utilizable nutrients to the animal's tissues which in turn is largely governed by the ability of rumen microbes to degrade plant cell walls. Although the degradability of dry …

Apparent Digestibility, Dynamics Of Rumen Fermentation And Sites Of Digestion Of Hays Of Leucaena Leucocephala (Lam) De Wit Cv. Peru, N M. Rodreiguez, I Borges
IGC Proceedings (1977-2023)
Protein deficiency, among others, is a common problem for livestock production in tropical regions. The use oflegumes has been suggested as a solution and Leucaena leucocephala has shown a great potential due to its capacity of nitrogen (N) fixation and dry matter (DM) production (NAS, 1984). However, very little is known about its nutritive value regarding its protein-energy balance and the process of digestion. The present work aimed the evaluation of the nutritive value of hays of Leucaena leucocephala cut at two stages of growth, through trials of apparent digestibility, dynamics of rumen fermentation and partition of digestion.

In Situ Degradation Of Cell Wall Neutral Sugars Of Normal And Brown Midrib Sorghum X Sudangrass Hybrids, K J. Moore, J O. Fritz, E H. Jaster
IGC Proceedings (1977-2023)
The nutritive value of forage for ruminants is limited by the digestibility of the complex polysaccharides cellulose and hemicellulose by rumen microbes. In grasses, the polysaccharide fraction of the cell wall is composed largely of polymers of neutral sugars and to a lesser extent uronic acids. Cellulose is a high molecular weight linear polymer of B-1 ➔ 4) linked Dgluco-pyranose units. Hemicellulose is a complex mixture of linear and branched-chain heteropolymers containing xylose, arabmose, mannose, galactose, glucose, and uronic acids (Van Soest, 1982). Lignification of the cell wall is a primary factor limiting the digestion of cell wall polysaccharides. Close …

Feed Evaluation Using Mobile Dacron Bags And Influences Of The Diet Composition, H Anzola, F N. Owens
IGC Proceedings (1977-2023)
The Mobile Nylon Bag (MNB) technique has been used successfully in protein nutrition studies with swine (Sauer et al., 1983) to determine amino acid availability from protein in specific feedstuffs. Canadian researchers also have tested this technique to predict site of digestion in ruminants (Kirkpatrick and Kennelly, 1987). Differences in small intestinal digestion may explain why animal responses differ to dietary protein sources which have similar ruminal escape values (Owens, 1986). The MNB holds promise to appraise the intestinal availability of undegraded dietary protein though further developmel).t and testing are needed. The objective of this experiment was to examine the …

Prediction Of Digestibility And Protein From Growing Degree-Days For Crested And Western Wheatgrass, A` B. Franck, J F. Karn
IGC Proceedings (1977-2023)
Morphological development of crops, including cool-season forage grasses, is mainly a function of air temperature. Morphological development of plants has been predicted from thermal units expressed as growing degree-days (GDD) (Franck, 1985 ; Wang, 1960). The use of thermal units also provides a predictive measure for managing forages based on growth stages rather than dates. However, forage digestibility ��nd crude protein (CP) content generally decrease as morphological development and time increase (Kamstra, 1973 ; Kilcher and Troelsen, 1973). The relationship between thermal units and forage digestibility and CP has not been defined for crested and western wheatgrasses. The primary purpose …
