The BeefSpecs fat calculator is a decision-support system developed to assist decision making on-farm to improve compliance rates with beef carcass specifications. BeefSpecs is underpinned by a research model run in conjunction with a translation process that converts inputs recorded in live animal and carcass assessment language into research model parameters. In contrast to many other research modelling systems, the changes in body composition predicted by the research model that underpins BeefSpecs are driven by growth rate. Use of this model removes the need for information concerning feed intake and dietary characteristics, which are impractical to collect on a routine basis in commercial production systems. A translation process was developed to use traits that are recorded routinely on-farm during normal production activities while allowing the original modelling system to run efficiently and accurately. This process aligns BeefSpecs with the language used by industry and increases the confidence of users in the underlying model theories. The outputs produced by BeefSpecs include final liveweight, final subcutaneous fat depth and hot standard carcass weight at the end of a specified feeding period. These traits contribute to the carcass specifications used to determine carcass value in the domestic and international markets supplied by the Australian beef industry, which directly aligns BeefSpecs with the decision-making styles of beef producers. During the development of BeefSpecs, potential users were consulted and enlisted in the evaluation process.

Surgical castration is a painful husbandry procedure performed on piglets in the United States (US) to improve meat quality. Veterinarians play a crucial role in developing pain management protocols. However, providing pain management for castration is not common practice in US swine production systems. Therefore, the objective of the present study is to identify factors influencing swine veterinarian decision-making in regard to pain management protocols for piglet castration using focus group methodologies. Swine veterinarians (n = 21) were recruited to participate in one of three focus groups. Audio recordings were transcribed verbatim and analyzed by two independent coders who identified three areas of focus, including (1) the lack of approved products validated for efficacy, (2) economic limitations and challenges, and (3) deficient guidelines and training for veterinarians to develop protocols. Although participating veterinarians acknowledged the importance of pain management from an animal welfare standpoint, these barriers must be addressed to ensure that castration pain can be successfully mitigated on-farm.

Data on the total dissectible muscle and fat tissue from primal cuts of the left hindquarters of 356 crossbred steers and heifers, and from the entire left side of 98 Shorthorn steer carcasses were used to evaluate the usefulness of subcutaneous fat depth measurements between the 11th and 12th ribs for predicting carcass composition. Analyses revealed that the use of multiple fat depth measurements from different sites on one or both sides conferred no advantage over the use of the best single measurement. The major sources of variation in total weight of muscle and fat tissue from the crossbreds were breeding group, sex and weight. The residual variances remaining after adjustment for these sources of variation were significantly reduced (P < 0.05) by inclusion of a single fat measurement with reductions of 12.5% (muscle) and 22.0% (fat) provided by the carcass fat measurement and 7.1% (muscle) and 13.1% (fat) for the Krautkramer measurement. For the Shorthorn steers, line and weight were the major sources of variation and larger reductions in the residual variances (16.3% for muscle and 24.6% for fat) were obtained by inclusion of carcass fat in the model. The ultrasonic fat measurements were less effective than carcass fat and the Scanogram gave larger reductions in residual variance than the Krautkramer (e.g., 8.1 vs. 3.9% for weight of muscle tissue). The results of this study suggest that live animal ultrasonic measurements of subcutaneous rib fat depth can be used to achieve modest improvement in predictors of beef carcass composition.

The segment, which still has expansion potential, depends on innovation and technologies to be adopted, such as the adoption of management models in rural property, allowing to evaluate its performance and decision making. The objective of this work is to apply a management system in two properties with differentiated production systems in livestock, measuring the economic and zootechnical performance, provided to the producer information for his decision making in his production system. For this study, we selected three properties, one located in the county of Lambari do Oeste-MT, which adopts the production system of rearing, rearing and fattening and another in the county of Bandeirantes-MS, which uses the system of rearing and fattening. The study period comprised the years 2015 to 2017, using the data recorded by the producers themselves. From the data generated by the management system, it was possible to more detailed analysis of production costs and the influence of profitability on farm activities. The results indicated that economic performance is directly influenced by the management of production costs. The information generated by the management system for the producer, provided the most appropriate decision-making for farm property.   Keywords: Livestock production. Production resources.

Abstract Piglets raised in commercial production systems in the U.S. undergo painful management procedures, including surgical castration, tail docking and ear notching, without analgesia or anesthesia provision for pain relief. This is a significant animal welfare concern. There is an immediate need to identify the most practical and effective analgesia or anesthesia option for use on-farm. The objective of this study was to assess the efficacy of 2.0mg/kg firocoxib, administered to the sow and delivered transmammary to her piglets, and a vapocoolant spray (ethyl chloride) to reduce processing pain. Five-day old male and female Yorkshire-cross piglets were used. 2.0mg/kg firocoxib was administered to the sow intramuscularly 7h prior to processing piglets. An ethyl chloride spray was applied to the ears, tail and scrotum of the piglets immediately before ear notching, tail docking and surgical castration, respectively. Piglets were assigned to one of four treatment groups: firocoxib and vapocoolant spray (FV; n=32), firocoxib only (F; n=32), vapocoolant spray only (V; n=32), no treatment (CON; n=32). The observation period was from 24h pre- to 48h post-processing (specific time points = baseline, 0h, 1h, 2h, 4h, 7h, 24h, 30h, 36h, 48h). Preliminary results found piglets displayed significantly more pain-related behaviors at 24h and 30h post-processing than at most other time points (p&lt; 0.05). Piglets had significantly higher cranial temperatures at 7h post-processing than all other time points (p&lt; 0.05). There was a trend in FV and F piglets having a higher cranial temperature at 36h post-processing compared to V and CON piglets (p=0.08). All piglets had significantly higher hair cortisol levels at 4 vs 20-days old (p&lt; .0001); however, there were no significant treatment effects on cranial temperature, hair cortisol or pain behavior, suggesting firocoxib and the ethyl chloride spray were unable to significantly reduce piglet pain post-processing. Further study analysis is needed to confirm these initial findings.

Interval-valued T-spherical fuzzy set (IVTSFS) handles uncertain and vague information by discussing their membership degree (MD), abstinence degree (AD), non-membership degree (NMD), and refusal degree (RD). MD, AD, NMD, and RD are defined in terms of closed subintervals of that reduce information loss compared to the T-spherical fuzzy set (TSFS), which takes crisp values from intervals; hence, some information may be lost. The purpose of this manuscript is to develop some Hamacher aggregation operators (HAOs) in the environment of IVTSFSs. To do so, some Hamacher operational laws based on Hamacher t-norms (HTNs) and Hamacher t-conorms (HTCNs) are introduced. Using Hamacher operational laws, we develop some aggregation operators (AOs), including an interval-valued T-spherical fuzzy Hamacher (IVTSFH) weighted averaging (IVTSFHWA) operator, an IVTSFH-ordered weighted averaging (IVTSFHOWA) operator, an IVTSFH hybrid averaging (IVTSFHHA) operator, an IVTSFH-weighted geometric (IVTSFHWG) operator, an IVTSFH-ordered weighted geometric (IVTSFHOWG) operator, and an IVTSFH hybrid geometric (IVTSFHHG) operator. The validation of the newly developed HAOs is investigated, and their basic properties are examined. In view of some restrictions, the generalization and proposed HAOs are shown, and a multi-attribute decision-making (MADM) procedure is explored based on the HAOs, which are further exemplified. Finally, a comparative analysis of the proposed work is also discussed with previous literature to show the superiority of our work.

Conventional swine production evolved to routinely use antimicrobials, and common occurrence of antimicrobial-resistant Salmonella has been reported. There is a paucity of information on the antimicrobial resistance of Salmonella in swine production in the absence of antimicrobial selective pressure. Therefore, we compared the prevalence and antimicrobial resistance of Salmonella isolated from antimicrobial-free and conventional production systems. A total of 889 pigs and 743 carcasses were sampled in the study. Salmonella prevalence was significantly higher among the antimicrobial-free systems (15.2%) than the conventional systems (4.2%) (odds ratio [OR] = 4.23; P &lt; 0.05). Antimicrobial resistance was detected against 10 of the 12 antimicrobials tested. The highest frequency of resistance was found against tetracycline (80%), followed by streptomycin (43.4%) and sulfamethoxazole (36%). Frequency of resistance to most classes of antimicrobials (except tetracycline) was significantly higher among conventional farms than antimicrobial-free farms, with ORs ranging from 2.84 for chloramphenicol to 23.22 for kanamycin at the on-farm level. A total of 28 antimicrobial resistance patterns were detected. A resistance pattern with streptomycin, sulfamethoxazole, and tetracycline (n = 130) was the most common multidrug resistance pattern. There was no significant difference in the proportion of isolates with this pattern between the conventional (19.5%) and the antimicrobial-free systems (18%) (OR = 1.8; P &gt; 0.05). A pentaresistance pattern with ampicillin, chloramphenicol, streptomycin, sulfamethoxazole, and tetracycline was strongly associated with antimicrobial-free groups (OR = 5.4; P = 0.01). While showing the higher likelihood of finding antimicrobial resistance among conventional herds, this study also implies that specific multidrug-resistant strains may occur on antimicrobial-free farms. A longitudinal study with a representative sample size is needed to reach more conclusive results of the associations detected in this study.

SummaryThree seasons of on-farm experimentation to develop potato production from botanical or true potato seed (TPS) under cool fertile conditions in West Java, Indonesia, are described. Twenty-three farmers experimented with two production systems: use of transplants, and use of seedling tubers produced in nursery beds. There was little yield difference between the systems, but an apparent progeny × system × season interaction was observed. All progenies were more resistant to late blight than the present cultivars grown from tubers. Appropriate matching of progeny and system gave seed of comparable quality with, but total yields slightly less than, certified imported seed of cv. Granola. Ware quality was slightly better than that of cv. Granola. Production costs were markedly less than for a tuber crop, making TPS ideal for small, resource-poor farmers.

The evaluation of mineral resources development efficiency is a typical multicriteria decision-making issue. Meanwhile, due to the limited existing technology, there might be subjectivity, ambiguity, and inaccuracy of the measurement of the evaluation index of mineral resources development efficiency. In this paper, we, considering the incomplete information, use the hesitant fuzzy linguistic approach to describe the psychological hesitation and ambiguity of the decision-maker in the actual evaluation process and then construct the general model of the development efficiency evaluation of the mineral resources by using the hesitant fuzzy linguistic terms sets and modified TODIM. Finally, this paper takes the Panxi area as an example to study the development efficiency of vanadium-titanium magnetite. The results show that the hesitant fuzzy linguistic multicriteria decision-making (MCDM) approach can be implemented to mineral resources evaluation and resources management.
