This research arose from the need to aggregate computer vision technology and machine learning in sheep weight control facilitate weighing process of animals farms. The experiment was conducted collect images their weights, later, annotations were made, generating a mask image dataset. We selected attribute extraction algorithms that extracted shape, size, angles with k-curvature. With these data, we used stratified five-fold cross-validation. Also, eight techniques aimed at regression,...
Abstract Our hypothesis suggests an improvement in carcass and meat quality of pasture‐finished animals by introducing concentrate feed into diets. This study aimed to evaluate the effect different levels protein‐energy supplementation on characteristics Texel lambs raised Brachiaria pastures, compare results with those obtained from confined animals. Thirty 2‐month‐old intact were divided five treatments: pasture mineral supplementation, containing daily supplies 0.8, 1.6, 2.4% BW...
The present study tested brown propolis in crude or extract form as a feed supplement for feedlot lambs to identify the type that most improves vivo nutrient digestibility. Digestibility was assessed by both total fecal collection and internal markers results obtained these techniques were compared. completely randomized design used compare intake digestibility of 24 male aged seven months among four dietary treatments (crude propolis, ethanol extract, monensin sodium, control). Methods...
RESUMO Objetivou-se avaliar o efeito dos resíduos da extração hidroalcoólica de própolis tipos verde e marrom sobre desenvolvimento bactérias Gram-positivas Gram-negativas. As brutas foram adquiridas apicultura “Companhia Abelha”, instalada em Contagem, Minas Gerais. A foi derivada “alecrim-do-campo” (Baccharis dracunculifolia), a (B. dracunculifolia) “assa-peixe” (Vernonia polyanthes). Foram usados cinco níveis inclusão (0; 0,625; 0,125; 0,25; 0,5g) resíduos, além do controle para inóculo...
The aim of the research was to evaluate productive and reproductive performances ewes as a function supplementation offered suckling lambs. lambs were divided into two experimental treatments. Treatment (1) kept in pastures Brachiaria-grass receiving mineral supplementation; treatment (2) concentrate creep-feeding. Regardless nutritional lambs, all matrices (female ewes) received 350 g daily. Ewes from treatment-1 presented average 49 days return estrus. treatment-2 presented, on average, 36...
Based on the assumption that time required by lamb to reach a certain weight at slaughter (slaughter weight) is partially dependent amount of milk ingested during suckling, and dietary management sheep lamb. Our study proposes examine effects weaning system productive reproductive performance ewes supplemented with creep-feeding grazing Marandu pastures their lambs weaned two different ages (60 90 days). Ewes were divided into treatment groups (weaning ages) according birth type (single or...
This study aimed to examine the weaning age (60 and 90 days) of lambs supplemented while grazing on Urochloa brizantha cv. Marandu pasture. Production performance, incidence worm infections, intoxication, production cost lambs, beside that body condition occurrence single or twin births in ewes were evaluated, by two consecutive years. There was no effect year. Lambs weaned at days consumed more supplement (281.0 g/day) than those 60 (210.2 showed a higher total weight gain (20.76 kg vs....
The addition of levels ethanol extract brown propolis was evaluated by assessing diet degradation in rumen fluid and predicting cumulative vitro gas production nonlinear (dual pool logistic exponential) models. A total 35 g crude were extracted 65 mL cereal alcohol (95% ethanol). In a completely randomized factorial design, the experimental diets combined four concentrations diluted (0, 50, 70, 100% extract) supplementation doses (4, 8, 12, 16, 20 mL/kg dry matter), tested triplicate. Diet...
The aim of this study was to evaluate the effect different inclusion levels semi-purified glycerine in diet feedlot lambs on feeding behaviour, nutrient intake and digestibility, carcass characteristics, meat quality vitro degradability. Thirty-two Dorper × (Texel Suffolk) crossbred intact male (22.2 ± 5.51 kg) were fed (90% purity) at 0, 120, 240 or 360 g/kg dry matter (DM) a total mixed ration with roughage concentrate ratio 40:60 for 84 d. In degradability not affected by supplementation....
It aimed to estimate the forage intake by lambs managed in different leaf allowances on Brachiaria-grass using internal and external markers. Forty-eight Texel with 17.52 ± 3.48 kg were evaluated which 12 testers 36 regulators. The kept twelve paddocks, subdivided into four treatments based green allowance (60, 75, 90, 105 g/kg of BW). experimental design was completely randomised. To dry matter (DMI), following markers used: indigestible (iDM); neutral detergent fibre (iNDF); acid (iADF);...
The study evaluated the effects of dietary protein-energy supplementation on feed intake, ingestive behavior, rumen parameters and nutrient digestibility in lambs. Four castrated lambs with 31.9 kg mean body weight fistulated were tested. distributed into latin square design (4x4), four treatments tested over periods time: no (control) or at 8, 16 24 g kg-1 weight. supplement (soybean meal, soybean hulls, ground corn minerals) was provided roughage (Tifton Bermudagrass, Cynodon spp., hay),...
This study aimed to identify the best green-leaf offerings of Urochloa brizantha cv. Marandu for pasture-finished lambs receiving protein-energy supplementation at rate 1.6% their body weights (BW). The animals were assigned into four treatments, which consisted varied offerings, namely, 105, 90, 75, or 60 g dry matter/kg weight Sixty-eight contemporary Texel × mixed-breed with an average initial BW 22.6 kg used over two years experiment. experiment was set up in a completely randomized...

O Laboratório Vivências nas Ciências Agrárias desenvolveu um sistema de aquaponia para disseminar conhecimentos alternativas produção a sociedade nos anos 2018 e 2019. Aquaponia é o nome dado ao cultivo peixes associado plantas. Apesar várias regiões do Brasil ainda não sofrerem escassez água, crescente pressão sobre seu uso impulsiona pesquisas sistemas cultivos com reutilização. A vem encontro da demanda por sustentáveis organismos aquáticos pode ser praticada em pequenos espaços, como...
