Hi, what are you looking for? Ali Robertson October 7, The results demonstrated that these traits could be genetically inherited and improved, along with other traits. The severity of nutritional restriction in beef cattle during the last trimester of gestation could affect fetal and postnatal growth and the physiology of the progeny.
Maternal nutritional restriction in late gestation decreased the birth weight of offspring; however, severe restriction induced early postnatal compensatory growth. Events in fetal life play an important role in alterations of fetal organogenesis in response to maternal and fetal nutrition.
These adaptations could permanently alter metabolism and manifestations throughout your life. The Morada Nova breed is an important animal genetic resource created by sheep farmers in the Brazilian semi-arid region. This breed has three genotypes: white, black and red. Our investigation sought to understand the thermoregulatory, acid—base and electrolytic dynamics of these genotypes according to the time of the day morning, noon and end of the day in the rainy and dry periods.
All genotypes were able to return to homeothermy at the end of the day, regardless of the period. The diet of cattle affects the composition and quality of beef, including its fat composition, flavour and colour.
The study showed that partial replacement of barley with either of two forms of maize in cattle diets influenced the fat composition of beef but had minimal effects on its colour or off-flavour development during storage. The implication is that while partial inclusion of maize in beef cattle diets alters beef composition, it is unlikely to adversely affect quality perceptibly.
Eugenol is a bioactive compound with defined attributes, including a role in reducing oxidative stress, being an interesting candidate for in vitro embryo production in cattle. Therefore, this study provided information of a new natural antioxidant, eugenol, representing a lower cost alternative capable of improving the efficiency of in vitro embryo production in cattle.
In sheep extensive production systems, pasture availability decreases in winter; thus, ewes are undernourished during gestation. Maternal melatonin treatment could mitigate intrauterine growth restriction induced by maternal undernutrition, enhancing bodyweight at birth and body temperature of lambs, and improving ewe—lamb behaviours at birth.
In this study, only lamb hip surface temperature was enhanced after birth, whereas ewe—lamb interactions, lamb birthweight and rectal temperature were unaffected by melatonin treatment. The use of breed crosses is an alternative for increasing animal production. For this purpose, breeds such as the Aberdeen Angus are already widely used, while Canchim animals present themselves as a viable alternative.
Crossbred animals have better carcass characteristics and initial freezing for more than 30 days resulted in more tender meats. The use of buserelin GnRH agonist can improve semen quality; nevertheless, the dosage, and frequency and time of application, are unresolved owing to the reported subsequent negative feedback on endogenous production of testosterone.
Therefore, low doses of buserelin can be used, although further adjustments to the hormonal protocol are needed to obtain an effective improvement in sperm quality. Urea is used at a large scale in diets for animals such as cows, goats and sheep, mainly to reduce production costs related to feeding.
However, there is a concern about the risk of intoxication on livestock because of the fast release. We confirmed that carnauba wax is an efficient material for the slow release of urea in sheep diets because it provides better and safer nitrogen utilisation, helping ranchers to manage their animals.
Farmers, advisors and researchers need better methods for analysing farm work, to address challenges affecting the social sustainability and profitability of livestock farming.
We report results from the first Australian trial of a method developed in France for assessing farm work organisation: The Work Assessment Method.
Participating farmers reported that the Work Assessment Method provided insights not available from standard physical and financial analyses and the study provides a foundation for research to further develop the Work Assessment Method for Australian livestock production systems.
Palm kernel cake has the potential to reduce production costs without affecting performance or product quality. This knowledge allows us to make decisions on replacement with palm kernel cake when common ingredients are in short supply or at high prices. Measuring feed consumption in grazing beef cows is not accurate or practical.
Modelling approaches can be used to identify cows that wean more weight of calf per unit of feed required allowing genetic selection of more efficient cows. Water scarcity, often accompanied by limited water intake WI in livestock, may result in pre-slaughter stress, affecting meat quality parameters.
The effect of water restrictions levels with vitamin C VC supplementation was evaluated on the performance and meat quality of goat meat.
While bodyweight loss was lessened with VC supplementation and sensory attributes affected, limited WI had no negative effect on most of the meat parameters measured. Supplementation of VC can help reduce bodyweight loss during the period of water scarcity. A balanced supply of dietary amino acids AA is essential to optimise growth in young animals. Deficiency or excess result in adaptive mechanisms involving the regulation of feed intake. This review has highlighted the chemosensory mechanisms behind the onset of appetite or satiety following dietary protein- or non-protein-bound AA in pigs.
The mediation of gut-released hormones appears as a key process to control. The precise use of dietary AA has the potential to improve current pig nutrition practices. We have identified the key issues of greenhouse-gas production, continuity of water supply, sustainability of animal feed resources, climate resilience of livestock and social issues including family dynamics and population migration as being essential for their survival.
Many rural communities in Pakistan are well prepared for global warming and its consequences, but further investments from the corporate sector and governments are required to boost their long-term resilience. The microbial species and community structures of rumen and jejunum play a crucial role in digestion, absorption and metabolism in ruminants. The noticeable higher richness, diversity and evenness of microorganisms in rumen than jejunum showed the greatest ability for digest in rumen.
Our findings will be helpful for elucidating the relationships on nutritional and physiological functions between gastrointestinal microorganisms and their hosts in ruminants. Oil palm frond OPF is abundantly available throughout Southeast Asia and is a good source of roughage for feedlot cattle during the dry and monsoon seasons when other forage options are limited.
However, the use of OPF in ruminant feed is constrained by its complex fibrous structure and low digestibility. This study examined whether addition of bypass fat will increase animal performance and carcass quality and thus profitability under smallholder condition.
This plan was focussed on human nutrition, but it is worth considering implications for production animal science and parallels with animal nutrition. While there are different contexts, there remains much that the animal production nutrition and human nutrition communities can learn from each other.
This is associated with poorer health and production outcomes and therefore is of significant concern. Increasingly, the properties of phytochemicals are being understood to protect against oxidative stress, improving the health and productivity of poultry and pigs. Following the banning or decline in the use of antibiotic growth promotors AGPs , the use of probiotics in poultry production has increased rapidly. The present review describes recent advances in probiotic use in poultry, and focuses on the current understanding of gut health, how to assess it in chickens, and how to improve it via probiotic supplementation in poultry feeds.
In particular, it explains the mechanisms how probiotics produce health benefits to the host, including improvements in bird performance. A third of all food produced for human consumption globally is lost or wasted annually.
Livestock animals, including insects, could function as efficient bioprocessors for converting unavoidable food waste into valuable animal protein. To be successful in establishing a sustainable food waste to livestock feed industry, it will be critical to ensure feed safety is appropriately regulated to prevent adverse animal health, welfare, biosecurity, food safety, economic, market access and food insecurity outcomes.
To promote egg consumption among low-income people, the protein—energy requirement for quail egg production was tested. The present research aimed to bridge the gap in cultural understanding so as to maximise the potential of selling premium food products in the Asian market. The findings outline how two demographic groups Australian and Chinese see value in Australian pork.
Finding changes of bacterial community in cattle in response to different diets is important because feed is directly involved in the rumen fermentation process. The present study was conducted to determine the effects of supplementing protein and energy sources on the rumen bacterial community in cattle, and it was found that their communities are affected by these sources.
The results are interesting because they highlighted the importance of choosing appropriate dietary supplements for improving cattle production. The Qinghai Tibetan plateau is characterised as a harsh high-altitude environment inhabited by a large number of ruminants. Some gaps remain in the current understanding of whether rumen bacteria help the adaptation of ruminants to the harsh environments, and this was studied by comparing indigenous and introduced ruminants.
The present study showed that yak, which has evolved as a distinctive species with specialised physiological and anatomical adaptations, has a rumen bacterial population that favours its survival in this extreme environment. Starch escaping ruminal degradation reduces fermentation losses in the rumen for more efficient digestion and utilisation in the small intestine. This study evaluated an approach to enhance bypass starch to allow more starch to be efficiently utilised in the small intestine of goats.
Australian cattle herd structure, performance and production measures, mostly derived from survey data, may be precise but lack accuracy. Using a herd model that reconciled beef and dairy herd performance against — slaughter and live export statistics, the beef herd was calculated to be consistently within 30—40 million cattle 12—16 Mt for the past 35 years, well above survey estimates, with continually improving performance and production.
These results may alter how future survey data are collected, analysed and then used by beef businesses and associated research and advisory agencies. Annual liveweight production of cows in north Australian beef-breeding businesses, which along with value per kg constitutes business income, has not been well defined.
Liveweight production over the life of tropically adapted cows grazing four primary country types was highly variable, being limited by available nutrition, and increased to maturity, whereas efficiency remained constant. Relative to cows weaning calves, the loss of a conceptus or weaner had a larger negative impact on liveweight production than failure to conceive. Livestock production globally contributes Considerable reductions through the use of feed additives contribute to mitigating the role of livestock in global climate warming.
Improving beef cattle feed efficiency could reduce cost of production and impacts on the environment. We analysed ruminal fermentation patterns and microbial community of bulls with low and high feed-efficiency phenotypes, and found a negative relationship between animal feed efficiency and ruminal microbiota diversity and connectance.
Our results suggested that more efficient animals host a less robust microbial community, pointing out that rumen microbiota could be one of the biological factors associated with variation in cattle feed efficiency. The use of eco-friendly feed additives such as yeast in poultry diet as a tool for sustainable poultry farming in place of antibiotic has been advocated.
However, the effects of yeast-based diets on laying performance in chickens are conflicting. Pooled results from 16 studies showed that egg production increased with the addition of yeast in layer diet at a rate not exceeding 5 g per kilogram feed. Results suggest that yeast can replace antibiotics in the diets of laying chicken. An observational population-based epidemiological study was conducted in commercial northern Australian beef-breeding herds to describe reproductive performance and to quantify the prevalence and impact of the major risk factors.
Reproductive performance varied markedly both within and among country types. The proportion of females weaning a calf annually was much lower in the Northern Forest than in the other country types. A large epidemiological study known as the Cash Cow project was conducted in commercial beef breeding herds across northern Australia between and with the aim of determining and quantifying the effect of management, nutritional and environmental factors on reproductive outcomes.
Conjugated linoleic acid CLA is a well-documented health benefit for humans. However, CLA is predominantly produced endogenously via rumen biohydrogenation and it could be modulated by altering the relative abundance of Butyrivibrio fibrisolvens and B. Inclusion of sunflower oil and Piper betle powder in goat diet enhanced milk yield and milk composition, including the CLA concentration of milk. Notably, these supplementations in goat diet had mostly positive effects on animal performance. Only limited empirical evidence was found to support the lethal control of wild dogs.

Conclusions We assessed the potential of machine and deep learning genomic selection models for predicting fourteen different end-use quality traits at two locations in a soft white winter wheat breeding program.
Different cross-validation, forward, and across location prediction scenarios were tried for comparing different models and utilization of this approach in the breeding program. Owing to limited seed availability, time constraint, and associated cost, phenotyping for quality traits is delayed to later generations. However, the higher accuracy of prediction models observed in this study suggest that selections can be performed earlier in the breeding process.
Machine and deep learning models performed better than Bayesian and RRBLUP genomic selection models and can be adopted for use in plant breeding programs, regardless of dataset sizes. Furthermore, the increase in forward prediction accuracy with the addition of more lines in the training set concluded that genomic selection models should be updated every year for the best prediction accuracy.
Overall, this and previous studies showed the benefit of implementing genomic selection with machine and deep learning models for different complex traits in large scale breeding programs using collected phenotypic data from previous years.
