The aim of this experiment was to determine the site and extent of digestion of nutrients in sheep fed broiler litter alone (100% litter treatment), broiler litter plus 7.5% sugarcane molasses (92.5% litter treatment) and broiler litter plus 15% molasses…
The aim of the study was to evaluate the nutritional value of Panicum maximum cv. Gatton for sheep production in three different seasons and at three different stages of maturity. More mature pasture, compared to younger pasture, resulted in lower…
(Co)variance estimates for birth weight, pre-weaning lamb survival and weaning weight were obtained for Merino lambs derived from 16 bloodlines. Between bloodline variance ratios (± s.e.) amounted to 0.10 ± 0.04 for lamb birth weight, 0.053 ± 0.036 for lamb…
The purpose of this review is to define possible breeding objectives for Southern African beef cattle farmers and to review different means of expressing genetic reproductive merit. The breeding objective considered was to maximize the number of calves born or…
Simmentaler cows grazing Cymbopogon-Themeda veld in the western Highveld region of South Africa (1985/861989/90) received three levels of phosphorus (P) supplementation. Dicalcium phosphate content of the supplement was manipulated to give intakes of 8 (CS), 4 (HS) or 0 (ZS)…
The effects of four diets containing different protein sources on the performance and gut histology of piglets were compared. The diets contained as the main protein sources either: milk powder plus fishmeal, milk powder plus high-protein (48% crude protein) soyabean…
Data from a multibreed composite beef cattle population managed under intensive irrigated grazing conditions were used to estimate direct additive heritabilities (h2a) and maternal heritabilities (h2m) for birth weight (BW) and weaning weight (WW) of the calf and cow efficiency…
Data from a multibreed composite beef cattle population, managed under intensive irrigated grazing conditions, were used to estimate direct additive heritabilities (h2a), maternal heritabilities (h2m) and maternal permanent environmental effects (c2) birth weight (BW) and weaning weight (WW) of the…
In the first study dry matter (DM), organic matter, crude protein (CP), neutral detergent fibre (NDF) and soluble carbohydrate (SC) concentrations were determined in whole leaves and the upper and lower sections of whole leaves of the Agave salmiana (Otto…
To investigate the possibility of a genotype x environment interaction in Bonsmara cattle, a cluster analysis was performed on weaning weight records of 72 811 Bonsmara calves, the progeny of 1 434 sires and 24 186 dams in 35 herds…
The effects of production system (feeding regime and time on feed) on growth performance, yield and economics and the effects of feeding regime, pre-slaughter treatment and electrical stimulation on meat quality were evaluated. Sixty Bonsmara steers were divided into three…
Thirty Boer and 27 Kiko does were exposed to Spanish bucks and evaluated for doe reproduction, pre-weaning kid growth, and production efficiency in the humid, subtropical south-eastern United States. Does of each breed were represented by at least seven seed…
The portable fibre-testing instrument OFDA2000 has applications in the mohair industry for both fibre classing and animal selection. A comparison was completed between single-staple mid-side testing using an OFDA2000 and conventional laboratory mid-side testing using an OFDA100. Mid-side mohair samples…
Genetic improvement is a key to future increases in productivity in the Australian Mohair industry. Accurate identification of superior sires is part of this process. A progeny test was established to evaluate some prominent sires in use within the Australian…
The erosion of the Kalahari Red with red Boer goats is a major concern among breeders. Little empiric information is available with no comprehensive system of monitoring special characteristics. Eighteen microsatellite markers were applied to investigate the genetic diversity of…
Caprine arthritis encephalitis (CAE) is a retroviral infection of goats. CAEV is closely related to the virus which causes Maedi- Visna in sheep and AIDS in humans. The first survey of the seroprevalence of CAEV in Hungarian goats was performed…
This is a genetic characterisation of the Blanca Serrana Andaluza goat breed based on microsatellite markers. Fifty animals from five herds were typed with a set of 27 microsatellites proposed by the FAO and ISAG for biodiversity studies. Our results…
The type and frequency of goat milk protein alleles have not yet been studied in Hungary. Here we report the initial, partial characterization of allelic polymorphisms of αs1-, к-casein and β-lactoglobulin genes in a herd of Hungarian Milk Goat based…
The aim of this study was to quantify the partial digestion of organic matter (OM), nitrogen (N) and neutral detergent fibre (NDF) in sheep grazing Panicum maximum cv. Gatton pastures at three stages of pasture maturity during summer, autumn or…
Milk production and milk composition responses to supplementation of Holstein-Friesian cows grazing kikuyu pasture in summer and a combination of annual ryegrass and maize silage in winter with 64 mg/d flavophospholipol were determined. There was no difference in the average…
