Diversity and nutritional properties of Pakistani dates: implications for sustainable value chain and decent living perspectives of rural households
(2016-02-09)
Date palm (Phoenix dactylifera L.) occupies almost three percent of the total worldwide cultivated area, with an annual production of seven million tonnes (t). Pakistan is an ideal place for the cultivation of date palm due to its sandy loam soil and semi-arid climate. In 2012, Pakistan produced 600,000 t of dates, on an area of 95,000 ha. Baluchistan province is the country’s top date producer, followed by Sindh, Punjab and Khyber Pakhtunkhwa (KPK) provinces. More than 300 date varieties are known to exist in Pakistan ...

Untersuchungen zu Qualität und Verträglichkeit ökologischer Milch
(2016-09-15)
In der Literatur findet sich eine kontroverse Debatte um eine Differenzierbarkeit ökologischer und konventioneller Produktqualität von Lebensmitteln. Zugleich greifen zahlreiche subjektiv überzeugte Verbraucher zunehmend zu ökologischen Lebensmitteln. Als eines der Kaufmotive wird in vielen Umfragen die Annahme eines höheren Gesundheitswertes und allgemein einer höheren Qualität ökologischer Produkte genannt. Bisher besteht hinsichtlich der Definitionen, Methoden sowie der Einordnung ökologischer Produktqualität keine ...

The Effect of Climate Variability on Main Components of Cow Milk in Iran
(2016-11-21)
The main purpose of this study is to assess the relationship between six bioclimatic indices
for cattle (temperature humidity (THI), environmental stress (ESI), equivalent temperature
(ESI), heat load (HLI), modified heat load (HLInew) and respiratory rate predictor(RRP)) and
fundamental milk components (fat, protein, and milk yield) considering uncertainty. The climate
parameters used to calculate the climate indices were taken from the NASA-Modern Era
Retrospective-Analysis for Research and Applications ...

Heat stress response for physiological traits in dairy and dual purpose cattle populations on phenotypic and genetic scales
(2016-02-23)
The main objective of this thesis was to determine the potential impact of heat stress (HS) on physiological traits of lactating cows and semen quality of bulls kept in a temperate climate. The thesis is comprised of three studies. An innovative statistical modeling aspect common to all three studies was the application of random regression methodology (RRM) to study the phenotypic and genetic trajectory of traits in dependency of a continuous temperature humidity index (THI).
In the first study, semen quality and ...

Entwicklung eines ökonomisch ausgerichteten Zuchtprogramms für die bedrohte Schweinerasse „Bunte Bentheimer“
(2016-03-03)
Das Ziel dieser Arbeit war, ein ökonomisch ausgerichtetes Zuchtprogramm für die bedrohte Schweinerasse „Bunte Bentheimer“ (BB) zu entwickeln. Ein wesentlicher Bestandteil von Zuchtprogrammen für bedrohte Rassen ist der Erhalt der genetischen Diversität durch Vermeidung von weiterer Inzucht und Reduzierung des Inzuchtzuwachses. In Kapitel 2 wurde die Population der BB unter Berücksichtigung der vorhandenen Abstammungsinformationen in Bezug auf genetische Diversität, Inzucht und Verwandtschaft analysiert. Durchschnittlicher ...

Exploring the potential of cassava in promoting agricultural growth in Nigeria
(Kassel University Press, 2016-05-27)
Cassava is one of the major food crops in Nigeria, with multiple uses from human consumption to industrial applications. This study explores the potential of cassava in Nigerian agriculture based on a review of cassava development policies; performs a trend analysis of the cultivation area, production, productivity, and real price of cassava and other competing crops for the period 1961–2013; identifies the sources of growth in production; and examines the production constraints at the local level based on a survey ...

Perception of quality in certified organic pineapples by farmers in Kayunga district, Central Uganda: Implications for food security
(Kassel University Press, 2016-05-04)
In East Africa, Uganda is one of the major producers of organic pineapples for export. These pineapples are mainly produced in central Uganda and have to meet stringent quality standards before they can be allowed on international markets. These quality standards may put considerable strain on farmers and may not be wholly representative of their quality interpretation. The aim of this paper is therefore, to determine the Ugandan organic pineapple farmers’ quality perception, the activities they carry out in order ...

Climate change adaptation strategies of maize producers of the Central Rift Valley of Ethiopia
(Kassel University Press, 2016-06-01)
The impacts of climate change are considered to be strong in countries located in tropical Africa that depend on agriculture for their food, income and livelihood. Therefore, a better understanding of the local dimensions of adaptation strategies is essential to develop appropriate measures that will mitigate adverse consequences. Hence, this study was conducted to identify the most commonly used adaptation strategies that farm households practice among a set of options to withstand the effects of climate change and ...

Meat yield and quality of Tanzania Shorthorn Zebu cattle finished on molasses/maize grain with agro-processing by-products in 90 days feedlot period
(Kassel University Press, 2016-04-26)
This study was conducted to evaluate the effects of feeding molasses or maize grain with agro-processing by-products on yield and quality of meat from Tanzania shorthorn zebu (TSZ) cattle. Forty five steers aged 2.5 to 3.0 years with 200 +/- 5.4 kg body weight were allocated into five dietary treatments namely hominy feed with molasses (HFMO), rice polishing with molasses (RPMO), hominy feed with maize meal (HFMM), rice polishing with maize meal (RPMM) and maize meal with molasses (MMMO). Ad libitum amount of each ...

The role of institutions as actors influencing Uganda’s cassava sector
(Kassel University Press, 2016-04-25)
We aim at mapping out a detailed framework that reveals the proportionate flow of cassava and its products along the value chain (VC). Furthermore, we aim at establishing the role of institutions and the linkages between institutions and other VC actors that influence the cassava VC in Uganda. We use both primary and secondary data obtained from four regions in Uganda. Results show that farmers, processors, transporters, traders, consumers and institutions are the major actors. There are four categories of institutions, ...
