... Feed efficiency is one of the economically important traits for the cattle industry that affects profit (feed costs) and the environment (production of manure and methane). Due to that feed efficiency is driven by multi-factors, mechanisms contributing to the animal to animal variation in this trait have not been well defined, limiting the development of precision feeding strategies to improve the ...

Abstract:
... Population growth and improving living standards are leading to a growing demand for beef. The understorey in the 19 million hectares of oil palm plantation worldwide represent a source of cattle feed, while also sparing additional land conversion for grazing. Research on cattle grazing under oil palm is novel and knowledge is lacking on long-term profitability and sustainability of the system, a ...

Abstract:
... The objective of this study was to explore perspectives and attitudes about euthanasia specific to the Brazilian dairy cattle industry. Twenty-five Brazilian citizens (13 veterinarians, 4 animal scientists, 3 professors, 3 researchers, 1 dairy owner, and 1 caretaker) participated in one of three focus groups conducted and recorded online (10, 8, and 7 participants per group). Questions regarding e ...

Abstract:
... Brazil is a key player in the global beef markets having generated 15% of global production, and approximately 20% of world exports in 2018. Productivity improvements will be indispensable if the Brazilian beef sector wants to maintain its position as a key player in both the domestic and international markets. In light of the aforementioned, this study makes two key contributions to the agricultu ...

Abstract:
... This study was an attempt at the analysis of the Zambia cattle population, its production systems and management practices using data collected during the 2017/2018 livestock and aquaculture census. The Public User Microdata Sample dataset provided by the Central Statistics Organization were analyzed using both qualitative and quantitative methods. Traditional system and free range grazing were fo ...

Abstract:
... HighlightsHydraulic fracking wastewater is evaluated as a possible alternative to freshwater in combination with beef cattle manure for bio-methane generation by anaerobic digestion (AD).Optimum conditions for AD with fracking wastewater remain unknown, but differ from AD with freshwater.Contrary to AD with freshwater, biogas production with fracking wastewater increased with lower MC.Abstract.

... Efforts to reduce greenhouse gas (GHG) emissions from cattle production have led to modifications of livestock diet composition aimed at reducing CH₄ emissions from enteric fermentation. These diet modifications can result in varied manure types that may differentially affect GHG emissions when applied to soil. The purpose of this experiment was to examine the effect of different manure types on G ...
... Assignment of individual cattle to a specific breed can often not rely on pedigree information. This is especially the case for local breeds for which the development of genomic assignment tools is required to allow individuals of unknown origin to be included to their herd books. A breed assignment model can be based on two specific stages: (a) the selection of breed‐informative markers and (b) t ...

Abstract:
... The coordinated interaction between the developing embryo and the maternal reproductive tract is essential for the establishment and maintenance of pregnancy in mammals. An early cross-talk is established between the oviduct/uterus and the gametes and embryo. This dialogue will shape the microenvironment in which gamete transport, fertilisation, and early embryonic development occur. Due to the sm ...

A review of the international literature also found that the amount and the presence in slurry of oestrus inducer hormone preparations used in intensive dairy cattle production has not been investigated. In our study, we followed the path of 5 different sex-inducing drugs (alfaglandin, PGF, dinolytic, gonavet, ovarelin) including three active pharmaceutical ingredients (D-Phe6-Gonadorelin, Klopros ...

Abstract:
... The expansion of the use of in vitro production techniques has revolutionized the bovine embryo market. In the last decade, we have seen the number of in vitro produced (IVP) embryos surpass the number of in vivo-derived (IVD) embryos obtained worldwide. Concomitantly, other biotechnologies were also improved, following the global trend. Embryo cryopreservation has received special attention, as i ...

The impacts of management-intensive grazing (MIG) of cattle on concentrations of total Escherichia coli, total suspended solids (TSS), and nitrate-nitrite nitrogen (NO₃ + NO₂-N), and occurrence of E. coli O157:H7 and selected antibiotic resistance genes (ARGs) in stream water and/or sediments were evaluated. Cattle were grazed for two-week periods in May in each of three years. Overall, grazing in ...
... Bovine babesiosis, which is caused by species of genus Babesia, is a leading cause of considerable economic losses to the cattle industry each year. Bovine Babesia species have frequently been detected in non-cattle hosts, such as water buffalo (Bubalus bubalis), from which the parasites can be transmitted by ticks to cattle. Therefore, Babesia infections should be minimized not only in cattle but ...

Abstract:
... Monitoring behaviour of the grazing livestock is a difficult task because of its demanding requirements (continuous operation, large amount of information, computational efficiency, device portability, precision and accuracy) under harsh environmental conditions. Detection and classification of jaw movements (JM) events are essential for estimating information related with foraging behaviour. Acou ...

... Microscale pyrolysis reactors are used to predict the properties of pyrolysis products and/or optimize operating conditions. However, a major challenge encountered with these systems concerns reactor scale-up, since the conception of an equivalent large-scale configuration involves a complex step of mathematical analysis of the process. Furthermore, the effect of scale for different reactor config ...

Abstract:
... Repeated use of the same drill bit during drilling wears off the cutting edges, which can lead to a significant increase in heat as a result of friction, which is harmful to a bone above 55 °C. Few previous studies have examined the effects of using the same drill bit several times, on temperature. The objective of this study was to determine the effect of each drilling on temperature and force. 7 ...

Tenure security has been identified as a key enabling factor for successful restoration initiatives. However, in Madagascar, a global biodiversity hotspot, dry forests are considered unoccupied and unowned, even where communities have long-established claims under customary tenure ...

... Negative economic impacts resulting from wildlife disrupting livestock operations through depredation of stock are a cause of human‐wildlife conflict. Management of such conflict requires identifying environmental and non‐environmental factors specific to a wildlife species' biology and ecology that influence the potential for livestock depredation to occur. Identification of such factors can impr ...
