Guidelines for the use and reuse of animals for teaching within veterinary medical education programs Open
Use and reuse of animals for educational purposes could adversely affect animal welfare. Guidelines for quantifying, monitoring, and planning the use and reuse of animals have been developed. Within this framework, animals are assigned poi…

Redclaw, Cherax quadricarinatus sex-separated rearing strategy enhances reproduction in females Open
Redclaw crayfish Cherax quadricarinatus, a tropical freshwater species, native to Northern Australia and is regarded as a promising species for global expansion of aquaculture. However, poor female fertility is a hindrance towards the comm…

Sustained‐release deslorelin acetate implants disrupt oestrous cyclicity in the mare Open
There is a need for a safe, effective and practical method of oestrus suppression in the mare. The aim of this study was to monitor ovarian activity in mares exposed to either 9.4 or 28.2 mg deslorelin acetate, a GnRH agonist, in the form …

Comparison of the initial ovarian response, the synchrony of oestrus and ovulation and chronic stress response after administration of 100 or 250 μg of <span>GnRH</span> to randomly cycling <i>Bos indicus</i> cattle Open
Objective This study investigated the effects of administering saline, 100 or 250 μg of gonadotrophin releasing hormone (GnRH) on ovarian response, synchrony of oestrus and ovulation and chronic stress response in Bos indicus cattle. Desig…

Immediate prepartum supplementation accelerates progesterone decline, boosting passive immunity transfer in tropically adapted beef cattle Open
Context Poor nutrition of late-pregnant cows is highly prevalent in the dry tropics and associated with high levels of calf mortality. Aims It was hypothesised that supplementation with protein to prepartum cows would restore the normal de…

Modification of a <span>GnRH</span>‐based system to synchronise oestrus in <i>Bos indicus</i> cattle improves pregnancy rates to <span>AI</span> in heifers but not cows Open
Objective To investigate if modification of a gonadotrophin‐releasing hormone (GnRH) based protocol to synchronise oestrus in Bos indicus cattle will improve response rates to the first administration of GnRH and improve pregnancy rates to…

Prepartum Supplementation to Improve Transfer of Passive Immunity and Growth Open
Late pregnant cows often experience nutritional stress in northern Australia, which reduces colostrum secretion, health, and likelihood of survival of neonatal calves. The effect of prepartum supplementation on the transfer of passive immu…

Use of a sanitary sheath at artificial insemination by nonprofessional technicians does not markedly improve pregnancy rates to artificial insemination in pasture-based dairy cows Open
Plastic sanitary sheaths over artificial insemination (AI) guns have been used at the time of AI to improve hygiene at AI and fertility in cattle, but fertility responses have been variable in studies when AI was performed by professional …

Enhancing Omega-3 Long-Chain Polyunsaturated Fatty Acid Content of Dairy-Derived Foods for Human Consumption Open
Omega-3 polyunsaturated fatty acids (n-3 PUFA) are termed essential fatty acids because they cannot be synthesized de novo by humans due to the lack of delta-12 and delta-15 desaturase enzymes and must therefore be acquired from the diet. …

Randomised controlled trial of the effect of concentration of progesterone before artificial insemination on fertility in ovulatory and anovulatory <span><i>Bos indicus</i></span> cattle Open
Objective To investigate the effect of concentration of progesterone (P4) before artificial insemination (AI) on fertility in ovulatory or anovulatory Bos indicus cattle. Design Randomised control study Methods The study included 162 heife…
