To overcome a lack of data on the use and acceptability of saline water for goats, a survey of saline water use by drought affected goat producers in Australia was completed. The responses (n = 31) from all but one…
Recent advances in analytical techniques have allowed hydro-geochemical databases to form an essential component of animal and human epidemiological studies. Geographically localised communities and livestock production systems have a higher incidence of risk factors, and therefore baseline concentrations of key…
This study evaluated the effect of level of by-pass protein supplementation (PSL) and body condition (BC) on ovarian activity and serum insulin (INS) concentrations on does. Does (n = 32, 19 mo.) with either a low BC (LBC = 2.1…
The vomeronasal organ (VNO) consists of paired, blind ending tubes on either side of the nasal septum. The VNO lumen connects to the nasopalatine canal and also to the oral and nasal cavities. The vomeronasal sensory epithelium is connected to…
The aim of this study was to evaluate the various alternations between long and short days of sunlight in an attempt to optimise the production of semen collected for artificial insemination (AI) under field conditions. The results suggest that alternation…
The aim of this study was to evaluate the extender composition, presence or absence of seminal plasma and dilution rate of spermatozoa for the preservation of fresh semen during three days before artificial insemination (AI). The percentage of kidding was…
South African indigenous does in rural communal farming systems kid for the first time at approximately 17 to 18 months of age. Does conceive at a relatively low body condition score (BCS ≈ 2.5 to 3) and their average litter…
Seasonal effects on semen quality of Gorno Altai cashmere goats and South African indigenous goats were studied in this experiment. A definite breeding season for the two breeds was determined. Semen quality parameters that were quantified include semen volume, sperm…
The acaricidal effect of the essential oil of the flowers of Ageratum houstonianum on Rhipicephalus lunulatus was tested in the Laboratory of Parasitology of the University of Dschang in the Western Highlands zone of Cameroon. Five doses of the essential…
Infection with gastrointestinal nematodes (GIN) is a primary constraint to economic goat production in the southern USA. Anthelmintic resistance is highly prevalent in goat nematodes in this region, and non-chemical control methods are needed. Grazing of forages containing condensed tannins…
A study was carried out in Southern Italy on 90 Siriana breed goats with naturally occurring infections of gastrointestinal nematodes. Six similar groups of 15 goats were formed, one untreated control group and five groups treated once with ivermectin (I…
Saanen and South African Indigenous goats were crossbred, and all three types were compared in terms of productivity, milk production and diseases between 1988 and 1994. Clinical mastitis occurred in the herd at a moderate level (28 cases of clinical…
Saanen milk goats were crossed with South African Indigenous goats to evaluate productivity, milk production and disease incidence, and to assess their suitability for milk production by small-scale farmers and households in developing areas. Goat kids were separated from their…
Antibiotic residues in goat milk were measured in two trials. In Trial 1, eight goats were treated with Curaclox LC and six goats were untreated controls. All goats were in early lactation except for one. Withdrawal periods of Curaclox LC…
Meat with a low pH is generally paler than at a high pH. Paleness related to pH is caused by light scattering. Myofibrils are a primary cause of pH-related light scattering in meat, but light scattering is also related inversely…
For many, the terms efficiency in food production and sustainability are perceived to be mutually exclusive. This perception is often the result of too narrow a definition of sustainability. This paper reviews the sustainability of efficient dairying systems using the…
The study investigated genetic parameters for egg and chick production recorded over an 8-month breeding season, as well as average egg and chick weight for pair-bred ostrich females. Estimates of h² were moderate for reproduction traits and very high for…
Data, collected during the 1997-1998 breeding season from 14 ostrich trios, were used to determine whether two females in a trio could be differentiated based on egg size. For eight of the trios a difference between egg weights could be…
The potential of red vine husks and pips as a component of animal feed was investigated. Twenty-five Dohne Merino ram lambs (mean live weight ± s.d. = 41.4 ± 2.3 kg) were used. A completely randomised design was used and…
The effect of aging the M. longissimus dorsi of 13 impala at 4ºC over a ten-day period was investigated. Large variation between animals was observed for the percentages drip and cooking loss as well as for the CIELab colour (L*,…
