The objective of the present study was to examine factors associated with death neonatal lambs. Postmortem autopsy data were collected from 3198 newborn lambs in Sheep CRCs Information Nucleus Flock situated various environments throughout southern Australia. proportion dying by category highest lowest starvation–mismothering (25%), stillbirth (21%), birth injury (18%), dystocia (9%), utero–prematurity (10%), predation (7%), cold exposure (5%), undiagnosed (4%), infection (1%) or...
Semi-intensive free-range farm systems are common in Australia, and these frequently practise on-range feeding. The objective of this study was to investigate the benefit choice feeding on flock performance, egg quality, range use laying hens using black soldier fly larvae (Hermetia illucens, BSF). A total 160 mature ISA brown hens, previously determined daily, were allocated a control group (control) or treatment (BSF) with various replicates depending parameter investigated. All fed ad...
The number and size of free-range laying hen (Gallus gallus domesticus) production systems are increasing within Australia in response to consumer demand for perceived improvement welfare. However, variation outdoor stocking density has generated dissatisfaction leading the development a national information standard on egg labelling by Australian Consumer Affairs Ministers. current Model Code Practice Domestic Poultry states guideline 1500 hens/ha, but no maximum is set. Radio-frequency...

The present paper covers reproductive performance in an artificial-insemination (AI) program of the Sheep CRC Information Nucleus with 24 699 lambs born at eight locations southern Australia across five lambings between 2007 and 2011. Results from AI frozen semen compared well industry standards for natural mating. Conception rates averaged 72%, 1.45 were per ewe pregnant Merino ewes 1.67 crossbreds. Lamb deaths 21% 15% crossbreds 19%, 22% 20% that mated to terminal, maternal sire types,...
Free-range laying hen systems are increasing within Australia and research is needed to determine optimal outdoor stocking densities. Six small (n=150 hens) experimental flocks of ISA Brown hens were housed with access ranges simulating one three densities two pen replicates per density: 2000 hens/ha, 10 000 hens/ha or 20 hens/ha. Birds provided daily range from 21 36 weeks age the usage 50% was tracked using radio-frequency identification technology. Throughout study, basic external health...
Baseline information on demographics and practices semi-intensive free-range egg farms with an outdoor stocking density of ≤1500 hens/hectare in Australia is presented. Free-range production changing the structure industry a broad variety tiers systems have emerged due to lack concrete legislative standards densities past. Information was extracted from pre-existing online poultry survey dataset, consisting total 79 questions related nutrition, pasture management, welfare health, animal...
Free-range laying hen systems are increasing within Australia. The pullets for these typically reared indoors before being provided first range access around 21 to 26 weeks of age. Thus, the rearing and environments disparate hens may not adapt well free-range housing. In this study, we 290 Hy-Line® Brown day-old chicks divided into two rooms each with feed, water litter. enriched room, multiple structural, manipulable, visual auditory stimuli were also from 4 days, non-enriched room had no...
A survey of 72 thoroughbred trainers in several regions NSW was conducted to better define current grain feeding practices, and the risks involved with Australian racing industry. Results from indicate that horses industry are currently being fed an average 7.3 ± 0.23 kg concentrate per day, oats, commercial pre‐mixed diets corn most commonly used.

An online survey was designed to form the basis of a framework for welfare assessment extensively managed sheep in Australia. The focused on compromise and useful indicators. A total 952 people completed its entirety, representing four stakeholder groups: Public (53.6%), Producer (27.4%), Scientist (9.9%), Service provider (9.1%). Animal considered be important by all participating groups this (average score 3.78/4). Respondents felt grazing generally adequate but improvement desired...
The effects of light intensity during rearing and beak trimming dietary fiber sources on the incidence cannibalism were investigated with 2,880 ISA Brown hens. During period, chicks housed under two levels light: dim (i.e., 5 lx) bright 60 to 80 conditions: or without trimming. At 15 wk age, all birds transferred laying cages five per cage. 17 four diets containing different concentrations offered: a commercial (wheat) diet, high insoluble (millrun) soluble (barley) diet plus enzyme.
