This study investigated the seasonal effects of Rhus lancea and Celtis africana leaves on preference, intake, weight, and serum metabolites in South African indigenous, mature, male goats. Twelve mature, male goats weighing 34 ± 5.9 kg (mean ± SD) were…
Usefulness of red grape pomace (GP) by-product in ruminant rations is restricted by its high fibre content. Pre-treatment with exogenous carbohydrases may partly resolve this problem. Therefore, the effects of various levels of an exogenous fibrolytic enzyme mixture (Viscozyme® L)…
The study was conducted to evaluate the effects of adding a fibrolytic enzyme in combination with bacterial inoculants on the fermentation, chemical composition and aerobic stability of ensiled potato hash (PH). Potato hash silage (PHS) was produced by mixing 800…
The study was conducted to assess the effects of whey, molasses and exogenous enzymes on fermentation, aerobic stability and nutrient composition of ensiled maize cobs. Five treatments were ensiled in 1.5 L anaerobic glass jars over 32 days, namely i)…
The aim of this study was to determine and compare the digestion kinetics of two fibre sources (lucerne, maize stalk) in different segments of the digestive tract of geese. Sixty Jilin nongan white geese were divided into two groups and…
The culture outflow-rate from a specially designed pH-auxostat continuous culture system can be used to calculate the specific growth rates of different bacterial species on suspensions of cellulose or other insoluble substrates. Provided a constant concentration of substrate is maintained…
The intake of Digitaria pentzii grown with sulphur fertilizer (0,14%; + S) was almost 50% higher than that of unfertilized forage (0,08%; - S). Results showed no differences in plant anatomy or in rumen bacterial populations in sheep fed +…
In the Karakul sheep of Southern Africa four major pelt types can be identified, namely pipe curl, developed shallow curl, shallow curl and watersilk types. A study of the foetal skin was undertaken to determine whether histological differences do exist…
Factors influencing food plant selection by the blesbok (Damaliscus dorcas) were studied in an area with simple plant composition. Dicanthium pyllosum leaves were specifically selected by the blesbok. Cuticle analysis gave a ratio of 1 Dicanthium to 1,85 of all…
Diets with three energy concentrations and five protein concentrations, structured in a 3 x 5 factorial experimental design, were formulated for the pre-starter (2 – 10 kg), starter (10 – 30 kg), grower (30 – 60 kg) and finisher phases…
