A Supervised Deep Learning Model Was Developed to Classify Nelore Cattle (Bos indicus) with Heat Stress in the Brazilian Amazon Welligton Conceição da Silva, Jamile Andréa Rodrigues da Silva, Lucietta Guerreiro Martorano, Éder Bruno Rebelo da Silva, Cláudio Vieira de Araújo, et al. Animals, 2026 Non-invasive and intelligent technologies have been utilized to monitor agricultural systems in real time, facilitating expedient decision-making and the reduction in animal stress in diverse climatic conditions. The objective of this study was to develop a deep learning supervised model to classify Nelore cattle (Bos indicus) into two groups: those in comfort and those under thermal stress. Thirty cattle, aged between 18 and 20 months, were evaluated between June and December 2023, resulting in 676 samples collected across four daily periods (6:00, 12:00, 18:00, and 24:00). Biotic variables included rectal temperature (RT) and respiratory rate (RR), while abiotic variables included air temperature (AT) and relative humidity (RH). The neural network model exhibited an accuracy and recall of 72% but a low specificity of 42%. These metrics indicate that while the model is effective in detecting stress situations, it faces challenges in correctly identifying animals in thermal comfort, likely due to class imbalance and the need for additional input features to capture environmental adaptability. Consequently, it can be posited that supervised learning models are valuable tools for precision livestock farming, provided that discriminatory limitations are mitigated by refining input characteristics and data balancing.
Age at first mating and season of dam birth affect reproductive and productive traits of Mozambican Angoni cattle Abilio Paulo Changule, Leonel António Joaquim, Milton Paulo Morrombe, Hermenegilda Petersburgo Dias, Tiago Pereira Guimarães, et al. Translational Animal Science, 2025 This retrospective observational study aimed to evaluate the effects of age at first mating (AFM) and season of dam birth (SB) on age at first calving (AFC), birth weight of calves (BW), and calving interval (CI) in Angoni cattle in Mozambique. A total of 1418 records collected over a 25-year period (1995–2020) at the Angonia Research Station were analyzed using R software (version 4.3.2). The effects of AFM and SB on reproductive and productive traits were determined using the Kruskal-Wallis test and further analyzed with Dunn’s test to compare means between groups in case of showing significance. The least squares method was applied to assess the relationship among AFM, BW, and AFC through simple linear regression analysis. AFM significantly influenced BW (17.5–18.3 kg; P < 0.05), AFC (839–1431 days; P < 0.001), and CI (493–533 days; P < 0.05). SB significantly affected BW (17.5 vs. 18.2 kg; P = 0.025) and CI (502 vs. 521 days; P < 0.001), but not AFC (P > 0.05). These results highlight that both AFM and SB are critical factors influencing reproductive performance and should be considered in future breeding and selection strategies to optimize herd efficiency in tropical beef systems.
Improving Egg Quality in Tropical Environments: Assessing the Maize Meal Replacement by Wheat Bran and Soybean Oil in Laying Hen Diets Mariana Novela, Abilio P. Changule, Igor I. S. Munguambe, Florentina D. Chilala, Leonel A. Joaquim, et al. Veterinary Medicine and Science, 2025 BackgroundThe use of wheat bran (WB) in the monogastric animal feed is limited due to its high fibre content and low energy contents.ObjectivesThe current study evaluated the effect of replacing maize meal with WB, in the absence or presence of soybean oil, on egg quality and economic performance indicators.MethodsIn a completely randomized design, 36 ISA Brown laying hens (age: 40 weeks) were used. The hens were distributed in individual cages (4 individuals/cage; n = 4) and subjected to three treatments: T1 (basal diet), T2 (basal diet with 20% maize meal replaced by WB) and T3 (basal diet with 20% maize meal replaced by 17.5% WB and 2.5% soybean oil). To assess egg quality over an 8‐week period, the following parameters were calculated: egg weight, length and width, shell resistance and thickness, shell, yolk and albumen percentage, Haugh unit and yolk colour. For the economic assessment, feeding costs, production cost per egg, production cost per dozen eggs, gross revenue, gross added value, profitability index, contribution margins and break‐even point were calculated. The data were subjected to two‐way analysis of variance (ANOVA) and the Tukey test.ResultsThe partial replacement of maize meal with WB, in the absence or presence of soybean oil, showed no differences (p > 0.05) for all evaluated egg quality parameters; however, a significant reduction in gross revenue along with a notable increase in gross added value, profitability index and contribution margin was observed (p < 0.05). Regarding the break‐even point, no significant effect was observed (p > 0.05).ConclusionIt was concluded that the addition of soybean oil to diets containing 20% WB was as efficient as the basal diet regarding egg quality, together with an improvement of the economic performance.
Productive and economic effects of adding Bacillus amyloliquefaciens CECT 5940 to bread waste-based diets in laying hens Albertina Felizardo Manteiga, Abilio Paulo Changule, Nilza Jorge Manjate, Dercia Hilario Magaia, Florentina Domingos Chilala, et al. Veterinary World, 2025 Background and Aim: The high cost and limited availability of maize in poultry production necessitate the exploration of alternative feed sources. Bread waste (BW), a nutrient-rich by-product, offers a sustainable substitute. However, concerns regarding its protein degradation during processing and limited research in laying hens restrict its broader application. Probiotics such as Bacillus amyloliquefaciens CECT 5940 may enhance nutrient utilization and economic viability when combined with BW. This study aimed to evaluate the effects of partially replacing maize meal with BW, with or without the inclusion of B. amyloliquefaciens CECT 5940, on the productive performance and economic outcomes in laying hens. Materials and Methods: Sixty 52-week-old Lohmann Brown laying hens were randomly assigned to one of three treatments (n = 20 per treatment; 4 replicates of 5 hens each): (T1) basal diet; (T2) basal diet with 20% BW replacing maize; and (T3) basal diet with 20% BW and 0.8% B. amyloliquefaciens CECT 5940. Performance parameters and economic indicators, including feed intake, egg production, feed conversion ratios, gross revenue, contribution margin, and break-even point, were assessed over 45 days. Results: No significant differences (p > 0.05) were observed in laying rate, egg mass, feed conversion per dozen eggs, or live weight across treatments. Economically, substituting 20% of maize with BW significantly reduced feed cost per kilogram and egg production cost per unit and per dozen (p < 0.05). The inclusion of B. amyloliquefaciens further enhanced the profitability index, gross value added, and reduced the break-even point compared to T1 and T2 (p < 0.05). Conclusion: Replacing 20% of maize with BW, with or without B. amyloliquefaciens CECT 5940, maintains productive performance in laying hens while significantly improving economic efficiency. This strategy offers a viable and sustainable alternative to conventional feed formulations in poultry production. Keywords: Bacillus amyloliquefaciens, bread waste, egg production, feed cost, laying hens, poultry nutrition, probiotic.
Optimizing laying hen diets: effect of partial maize meal replacement with wheat bran or biscuits crumbs and Bacillus amyloliquefaciens CECT 5940 Albertina Felizardo Manteiga, Abilio Paulo Changule, Dercia Hilario Magaia, Nilza Jorge Manjate, Florentina Domingos Chilala, et al. Frontiers in Veterinary Science, 2025 BackgroundWheat bran (WB) and biscuit crumbs (BC) offer alternative feed sources for laying hens, potentially improving productivity and economic efficiency.ObjectiveThis work evaluated the partial replacement of maize meal with WB or BC, with or without the addition of Bacillus amyloliquefaciens CECT 5940, on the productive and economic performance of laying hens.MethodsFive treatments were allocated as follows: T1: a basal diet; T2: a basal diet where 20% of maize meal was replaced by WB; T3: a basal diet that included 20% of WB plus B. amyloliquefaciens CECT 5940; T4: a basal diet where 20% of maize meal was replaced by BC; and T5: a basal diet that included 20% of BC plus B. amyloliquefaciens CECT 5940. Productive parameters (live weight, laying rate, feed conversion per egg mass, feed conversion per dozen eggs, feed consumption, and viability) and economic metrics (feed costs, production cost per egg, production cost per dozen eggs, gross revenue, gross added value, profitability index, contribution margins, and break-even point) were assessed using ANOVA and the Tukey test.Main findingsA statistically significant (p &lt; 0.05) increase was observed in the LR and FC/dz when maize meal was partially replaced with BC. While the addition of B. amyloliquefaciens CECT 5940 to WB significantly improved LR and FC/dz when compared to T2 (p &lt; 0.05), no significant difference was seen for BC (p &gt; 0.05). As for the economic evaluation, both T2 and T3 significantly reduced production costs (p &lt; 0.05). Compared to T1, the partial replacement of maize meal with WB significantly reduced (p &lt; 0.05) gross revenue. The addition of B. amyloliquefaciens CECT 5940 significantly increased (p &lt; 0.05) gross value added, profitability index, and contribution margins, and significantly reduced the break-even point (p &lt; 0.05) in comparison with T1 for WB and BC both with (T3 and T5) and without B. amyloliquefaciens CECT 5940 (T2 and T4).ConclusionIt was concluded that the addition of B. amyloliquefaciens CECT 5940 to both WB and BC diets was as efficient as the basal diet in terms of productivity and improved economic performance.
Characterization of the Temperament and Reactivity of Nelore Cattle (Bos indicus) Associated with Behavior Scores during Corral Management in the Humid Tropics Welligton Conceição da Silva, Jamile Andréa Rodrigues da Silva, Lucieta Guerreiro Martorano, Éder Bruno Rebelo da Silva, Tatiane Silva Belo, et al. Animals, 2024 The evaluation of the reactivity and distress of cattle during corral management, by means of subjective scores, aims at the standardization of behavioral indicators, through non-invasive methods, in addition to enabling the development of more appropriate management practices, thus promoting the comfort and well-being of these animals. Therefore, in this study, we aimed to characterize the temperament and distress of cattle managed in a corral using behavioral indicators during the rainiest period. For this, the experiment was conducted on a property located in the municipality of Mojuí dos Campos, during the rainiest quarter (February–April). Thus, 30 male cattle, not castrated, approximately 29 months of age, clinically healthy, and weighing 310 + 20 kg, were divided into three rearing systems: silvopastoral (SP), traditional (SS), and integrated (SI) systems. There were 10 animals per system. Physiological parameters were collected to evaluate rectal temperature (RT) and respiratory rate (RR), as well as body surface temperature (BST), through thermal windows (head and flank infrared temperature and rump infrared temperature). To evaluate temperament and reactivity, scores indicative of corral behavior were used, namely escape speed (ES), tension score (SS_1), tension score (SS_2), reactivity scale (RS), movement score (MS), and temperament scale (TS). The results showed that there was a thermal amplitude of 5.9 °C on average and 8.6 °C at maximum when comparing the structure of the corral and the trees. In addition, the comparisons between the production systems for the behavioral variables did not differ at the 5% significance level, except for ES, where the traditional system differed from the integrated system and the silvopastoral system, showing intermediate average values for both. In addition, there was a positive correlation between the variables RT and RR (r = 0.72; p < 0.01), RR and SS_2 (r = 0.38; p = 0.04), flank infrared temperature and MS (r = 0.47; p = 0.01), rump infrared temperature and RS (r = 0.37; p = 0.04), SS_1 and RS (r = 0.41; p = 0.02), SS_1 and SS_2 (r = 0.39; p = 0.03), RS and SS_2 (r = 0.58; p = 0.00), RS and MS (r = 0.50; p = 0.01), RS and TS (r = 0.61; p = 0.00), SS_2 and MS (r = 0.51; p = 0.00), SS_2 and TS (r = 0.47; p = 0.01), and MS and TS (r = 0.44; p = 0.02), and a negative correlation between ES and TS (r = −0.42; p = 0.02). The rainy season had a major influence on the evaluation of temperature and distress levels during handling in the corral, as evidenced by the association between physiological and behavioral parameters.
Thermal Comfort of Nelore Cattle (Bos indicus) Managed in Silvopastoral and Traditional Systems Associated with Rumination in a Humid Tropical Environment in the Eastern Amazon, Brazil Welligton Conceição da Silva, Jamile Andréa Rodrigues da Silva, Lucieta Guerreiro Martorano, Éder Bruno Rebelo da Silva, Katarina Cardoso de Carvalho, et al. Veterinary Sciences, 2024 The objective of this study was to evaluate the thermal comfort of Nelore cattle (Bos indicus) managed in silvopastoral and traditional systems associated with rumination behavior in a humid tropical environment in the Eastern Amazon, Brazil. The study was carried out on a rural property in Mojuí dos Campos, Pará, Brazil, during the transition period of the year, from June to July 2023. Over these two months, six consecutive data collection days were held. We selected 20 clinically healthy non-castrated male Nelore cattle, aged between 18 and 20 months, with an average weight of 250 kg and body condition score of 3.5 (1–5). These animals were randomly divided into two groups: traditional system (TS) and silvopastoral system (SS). The physiological variables evaluated included RR, RT and BST. The variables were analyzed using the linear mixed model. For agrometeorological variables, higher values were observed between 10:00 a.m. (33 °C) and 6:00 p.m. (30 °C), with the highest temperature observed at 4:00 p.m. (40 °C). The RR showed interactions (p = 0.0214) between systems and times; in general, higher RR were obtained in the Traditional. The animals’ RT showed no significant difference (p < 0.05) between the production systems, but there was a statistically significant difference in relation to the time of collection (p < 0.0001). In the BGHI, it was possible to observe that there was mild stress in the period from 22:00 at night to 6:00 in the morning and moderate stress in the period of greatest increase in temperature, from 10:00 in the morning to 18:00 at night. BST showed no statistical difference between the regions studied or between the SP (35.6 °C) and TS (36.25 °C) systems. RT in the TS showed a positive correlation with AT (r = 0.31507; p = 0.0477). RT in the SP showed a positive correlation with THI (r = 35583; p = 0.0242). On the other hand, RT in the SP (r = 0.42873; p = 0.0058) and ST (r = 0.51015; p = 0.0008) showed a positive correlation with BGHI. RR in the TS showed a positive correlation with BGHI (r = 0.44908; p = 0.0037). The greatest amounts of rumination were carried out by animals in the SP system, generally ruminating lying down (p < 0.05). With regard to rumination behavior in the morning and afternoon, there were higher numbers of WS and LD in the TS (p > 0.05). Most of the time, the cattle were LD during the morning and afternoon shifts, and at night and dawn they were WS in the TS. Therefore, the SP offers more thermal comfort advantages compared to the TS system.
Thermographic Profiles in Livestock Systems under Full Sun and Shaded Pastures during an Extreme Climate Event in the Eastern Amazon, Brazil: El Niño of 2023 Welligton Conceição da Silva, Jamile Andréa Rodrigues da Silva, Lucieta Guerreiro Martorano, Éder Bruno Rebelo da Silva, Carlos Eduardo Lima Sousa, et al. Animals, 2024 The El Niño represents a substantial threat to pastures, affecting the availability of water, forage and compromising the sustainability of grazing areas, especially in the northern region of Brazil. Therefore, the objective of this study was to characterize the thermographic profile of three production systems in the Eastern Amazon, Brazil. The study was conducted on a rural cattle farm in Mojuí dos Campos, Pará, Brazil, between August and November 2023. The experiment involved livestock production systems, including traditional, silvopastoral and integrated, with different conditions of shade and access to the bathing area. An infrared thermographic (IRT) camera was used, recording temperatures in different zones, such as areas with trees, pastures with forage and exposed pastures. The highest mean temperatures (p = 0.02) were observed in pastures with full sun from August to November. On the other hand, the lowest average temperatures were recorded in areas shaded by chestnut trees (Bertholletia excelsa). The highest temperature ranges were found in sunny areas and the lowest were recorded in shaded areas. The highest temperatures were observed in the pasture in full sun, while the lowest were recorded in areas shaded by chestnut trees (p < 0.0001). The interaction between the systems and treatments revealed significant temperature differences (p < 0.0001), with the native trees showing an average temperature of 35.9 °C, lower than the grasses and soil, which reached 61.2 °C. This research concludes that, under El Niño in the Eastern Amazon, areas shaded by Brazil nut trees had lower temperatures, demonstrating the effectiveness of shade. Native trees, compared to grasses and soil, showed the ability to create cooler environments, highlighting the positive influence on different species such as sheep, goats and cattle.
