Response in antioxidant activity and shelf life of meat from broilers fed on incremental levels of Vachellia tortilis leaf meal.
(2018)The broad objective of the study was to determine the antioxidant activity and shelf life of meat from boilers fed on incremental levels of Vachellia tortilis leaf meal. One hundred and twenty Cobb-500-day old unsexed ... -
Response in carcass yield, organ weights and the gut morphology to Vachellia tortilis inclusion in broilers.
(2018)The broad objective of this study was to determine the response to incremental levels of Vachellia tortilis leaf meal on carcass yield, organ weights and gut morphology of broilers. Five-hundred unsexed cobb 500-day-old ... -
Response in fertility of windsnyer boars to increasing α-tocopherol supplementation.
(2017)Abstract available in PDF file. -
Response in physicochemical characteristics of broiler meat to incremental levels of vachellia tortilis leaf meal
(2018)The broad objective of the current study was to determine the relationship between inclusion levels of Vachellia tortilis and physicochemical attributes of broiler meat. A total of 120 Cobb 500 broilers were randomly ... -
The response of broiler breeder hens to dietary lysine : hatchability, embryo growth and subsequent offspring performance.
(2011)This study was conducted to determine the effects of breeder hen dietary lysine on offspring performance. In trial 1, Cobb 500 broiler breeder hens were fed 1200, 1070, 930 and 800 mg lysine/bird/d from 26 to 60 weeks of ... -
Responses in growing pigs to lysine and threonine limiting feeds and environmental temperature.
(1996)In this thesis two experiments were conducted. The objective of the first experiment was to measure the response of a range of dietary threonine concentrations and environmental temperatures on the performance of young ... -
A retrospective study of in situ and in vitro considerations in horse nutrition management.
(2017)The current changes occurring in equine feeding management to meet performance demands, do not take into consideration the repercussions on the digestive tract. The aim of this investigation was to determine the linkage ... -
Some factors affecting weaning weights of calves.
(1996)A mixed model study was carried out on the field data records of 9798 Simmmental and 1725 Hereford calves born during the period 1992 to 1994, and obtained from the Animal Improvement Institute, Irene. The records were ... -
A study of the Culcoides (Diptera: ceratopogonidae) vectors of African horse sickness to enhance current practical control measures and research methods.
(2011-01-17)African horse sickness virus causes a non-contagious, infectious disease of equids. It is epizootic to sub-Saharan Africa and parts of the Middle East. The epizootics caused by the virus have caused widespread devastation ... -
Suckling behaviour and fertility in beef cows on pasture.
(1990)The suckling behaviour of 66 Hereford and Simmentaler cows was studied. The average frequency of suckling in 24 hours was four times, and the average duration of each suckling bout was 10 minutes. Suckling events were ... -
Testing for passive transfer of immunity in foals, and an evaluation of the African horse sickness vaccination schedule.
(2005)This thesis comprises an introductory review of the literature, followed by reports of two experiments which are presented in the form of scientific papers. For this reason, there may be some repetition between chapters, ... -
The effect of dietary crude protein, organic selenium and vitamin E on fertility and semen quality of broiler breeder males.
(2008)There are negative influences of selection for broiler growth on the reproductive ability of broiler breeder parents. This is mostly due to problems related to excessive body weight, such as an inability to achieve successful ... -
The use of choice feeding and mixture experiments to evaluate protein sources used in broiler feeds.
(1997)No abstract available. -
The use of enzyme supplementation for wheat-barley diets in poultry as a means of improving productive performance.
(2010)The objective of the study was to evaluate the effect of an exogenous multi-blend enzyme ( -glucanase and xylanase) on the performance of the broiler chickens and laying hens fed diets based on wheat and barley. Experiments ... -
Use of indigenous methods to control gastro-intestinal nematodes in chickens.
(2018)Millions of resource-limited farmers depend on indigenous knowledge (IK) to sustain chicken health. The level of understanding on these IK systems is low. The objectives of the study were to: (1) explore IK used to control ... -
Use of inert markers to predict diet composition, forage intake, digestibility and passage rate in sheep.
(2019)The mechanisms that regulate intake and composition of selected diets in ruminants are complex and vary among animals of the same species and cross species. These are governed by highly variable aspects, which range from ... -
The use of the N-alkane technique for measuring herbage dry matter intake in horses.
(1995)The use of n-alkanes as indigestible markers for the estimation of herbage dry matter intake in grazing ruminants, is reported to have significant advantages over other markers used for this purpose (Dove and Mayes, ...
