The use of the N-alkane technique for measuring herbage dry matter intake in horses.
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, ...
The effect of different methods of controlling urolithiasis on ovine mineral metabolism.
The widespread use of high-energy, low roughage diets among feedlot sheep has lead to the development of several production diseases (Bide et al., 1973). One of the least easily identifiable is urolithiasis, yet it is ...
Suckling behaviour and fertility in beef cows on pasture.
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 ...
Capacitation of Nguni semen for in vitro fertilization of bovine oocytes.
In vitro maturation, fertilization and culture is a technique which is increasingly utilised in the animal science industry for embryo production. However, optimal conditions for in vitro maturation, fertilization and ...
Some factors affecting weaning weights of calves.
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 ...
Attempts to improve the yield of bovine blastocysts by incorporating insulin, selenium and transferrin in the In Vitro system.
To produce an embryo via in vitro maturation, in vitro fertilization and in vitro culture methods it is vital to obtain consistent results and at the same time a large number of bias to cysts from the immature oocytes ...
Responses in growing pigs to lysine and threonine limiting feeds and environmental temperature.
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 ...
The effects of dietary crude protein on fertility of broiler breeder males.
Fertility of Broiler Breeders (BBs) has been researched over many years with inconclusive findings. Genetic selection and improvements in growth traits have had negative effects on fertility of BB. One explanation is ...
Influence of feed bulk on physicochemical properties of digesta in pigs.
Physicochemical properties of fibre-based diets were used to determine the influence of feed bulk on physicochemical properties of digesta within each segment of the gastrointestinal tract and digesta in pigs. In the first ...
