Pregnancy rate and prolificacy after artificial insemination in ewes following synchronisation with prostaglandin, sponges, or sponges with bactericide
Animal Production Science - Tập 51 Số 6 - Trang 565 - 2011
C. Viñoles, B. L. Paganoni, John Milton, Marc Antoine Driancourt, Graeme B. Martin
Pregnancy rate and prolificacy were studied in ewes after cycle synchronisation by either progestagen sponges plus equine chorionic gonadotrophin (eCG) or by three injections of prostaglandin (PG). We also tested whether there was any advantage in treating the sponges with antibiotic before insertion. In Experiment 1, 207 Corriedale ewes were treated with intravaginal sponges for 14 days...... hiện toàn bộ
GPS observation of shelter utilisation by Merino ewes
Animal Production Science - Tập 51 Số 8 - Trang 724 - 2011
Donnalee Taylor, Derek Schneider, Wendy Brown, Ian Price, Mark Trotter, David Lamb, Geoffrey Hinch
The present study examined how shelter availability, altitude and temperature influence paddock utilisation by pregnant and lambing Merino ewes. Global positioning systems (GPS) attached to collars allowed continuous tracking of ewes’ positions within two paddocks, and environmental conditions were also monitored throughout this time using temperature loggers. Animal tracking devices (UNEt...... hiện toàn bộ
Ruminant enteric methane mitigation: a review
Animal Production Science - Tập 51 Số 6 - Trang 491 - 2011
DJ Cottle, J. V. Nolan, S. G. Wiedemann
In Australia, agriculture is responsible for ~17% of total greenhouse gas emissions with ruminants being the largest single source. However, agriculture is likely to be shielded from the full impact of any future price on carbon. In this review, strategies for reducing ruminant methane output are considered in relation to rumen ecology and biochemistry, animal breeding and management optio...... hiện toàn bộ
A new cactus variety for dairy cows in areas infested with Dactylopius opuntiae
Animal Production Science - Tập 59 Số 3 - Trang 479 - 2019
Carolina Corrêa de Figueiredo Monteiro, Marisa A. S. V. Ferreira, Antônia Sherlânea Chaves Véras, Sebastião Inocêncio Guido, Marina Paula Almeida, R. C. Silva, Jonas Gomes Inácio
Spineless cactus is an important part of dairy cow diet in the semiarid Brazilia. Severe infestation of cochineal (Dactylopius opuntiae Cockerell) destroyed a vast area of the most common species of cactus planted in the region; Opuntia ficus-indica Mill. resistant varieties with superior agronomic performance were recently selected, but they still need to be tested with dairy cows. We ev...... hiện toàn bộ
Revisiting summer infertility in the pig: could heat stress-induced sperm DNA damage negatively affect early embryo development?
Animal Production Science - Tập 57 Số 10 - Trang 1975 - 2017
Santiago T. Peña, Bruce Gummow, A. J. Parker, Damien B.B.P. Paris
Temperature is a crucial factor in mammalian spermatogenesis. The scrotum, pampiniform plexus, and cremaster and dartos muscles in mammals are specific adaptations to ensure sperm production in a regulated environment 4−6°C below internal body temperature. However, the limited endogenous antioxidant systems inherent in mammalian spermatozoa compounded by the loss of cytosolic repair mechan...... hiện toàn bộ
Future research priorities for animal production in a changing world
Animal Production Science - Tập 51 Số 1 - Trang 1 - 2011
Nigel Scollan, P. L. Greenwood, C. J. Newbold, David R. Yáñez Ruiz, Kevin J. Shingfield, R. J. Wallace, Jean-François J.-F. Hocquette
This paper reports the outcomes from an International Workshop on ‘Animal Production in a Changing World’ held in Clermont-Ferrand (INRA-Theix, France) on 9–10 September 2009 in which 35 participants from 15 different countries participated. The main objective was to discuss the main challenges within the livestock sector: its environmental impact and role in global climate change; balanci...... hiện toàn bộ

Forage intake, digestibility and performance of cattle, horses, sheep and goats grazing together on an improved heathland
Animal Production Science - Tập 57 Số 1 - Trang 102 - 2017
K. Osoro, L.M.M. Ferreira, U. García, A. Martínez, R. Celaya
A mixed herd of five cows, five mares, 32 ewes and 32 goats was managed with their offspring during two consecutive years in a paddock (22.3 ha) with 76% of heathlands and 24% of improved pasture area, with the aim of studying their differences in ingestive behaviour and performance. Diet composition, dry matter intake (DMI) and digestibility (DMD) were estimated on three occasions using...... hiện toàn bộ
Public concerns about dairy-cow welfare: how should the industry respond?
Animal Production Science - Tập 57 Số 7 - Trang 1201 - 2017
Daniel M. Weary, M.A.G. von Keyserlingk
Common practices on dairy farms have fallen out of step with public values, such that the dairy industry has now become a target for public criticism. In the present paper, we describe some of the forces that have led to the current situation, and various potential methods to rectify the situation. One approach is to shield industry practices from public scrutiny, for example, by using ‘ag...... hiện toàn bộ
