Abstracts: Thirty-two intact male goats from four genetic groups (eight pure-bred Boers, eight ¾ Boer + ¼ SPRD crossbreeds, eight ½ Boer + ½ SPRD crossbreeds, and eight ½ Anglo Nubian + ½ SPRD crossbreeds) were evaluated for meat quality. The goats were reared in confinement and slaughtered at the average live weight of 29 kg. Temperature and pH decrease in the longissimus dorsi muscle was determined for 24 hours, and analyses of colour, cooking loss, water-holding capacity, and sensory attributes were also performed. Genotype significantly (P < 0.05) influenced the confinement period; ½ Boer + ½ SPRD crossbreeds required the most time in confinement to reach the target weight, while the pure-bred Boers required the least time. Genotype also significantly influenced (P < 0.05) the weight loss due to cooking, shearing force, colour (intensity of yellowness and luminescence), and the sensory attributes of flavour, odour, and raw colour of the meat. The crossing of exotic Boer and Anglo Nubian breeds with the native SPRD resulted in a goat meat of high quality.
[Qualidade da carne de caprinos exóticos e mestiços SPRD da região semiárida].
Resumo:Trinta e dois caprinos machos não castrados de quatro grupos genéticos, oito da raça Boer Puro, oito mestiços de ¾ Boer + ¼ SPRD, oito mestiços de ½ Boer + ½ SPRD e oito mestiços de ½ Anglo Nubiano + ½ SPRD, foram utilizados para caracterizar a sua qualidade de carne. Os caprinos foram criados em confinamento e abatidos com o peso vivo médio de 29 kg. Em conjunto com as análises de cor, foram determinados o decréscimo da temperatura e do pH durante 24 horas no músculo longissimus dorsi, a perda de peso por cocção, a capacidade de retenção de água e sensoriais. O genótipo (p < 0,05) influenciou significativamente o período de confinamento: mestiços de ½ Boer + ½ SPRD apresentaram maior número de dias em confinamento, enquanto os Boer Puro alcançaram o peso final no menor período de dias. O genótipo também influenciou significativamente (p < 0,05) os parâmetros de perda de peso por cocção, força de cisalhamento e cor (intensidade de amarelo e luminescência) e os atributos sensoriais de sabor, odor e cor de carne crua. O cruzamento das raças Boer e Anglo Nubiana com os nativos SPRD resultou em carne caprina de elevada qualidade.

Nutrient-efficient root system architecture (RSA) is becoming an important breeding objective for generating crop varieties with improved nutrient and water acquisition efficiency. Genetic variants shaping soybean RSA is key in improving nutrient and water acquisition. Here, we report on the use of an improved 2-dimensional high-throughput root phenotyping platform that minimizes background noise by imaging pouch-grown root systems submerged in water. We also developed a background image cleaning Python pipeline that computationally removes images of small pieces of debris and filter paper fibers, which can be erroneously quantified as root tips. This platform was used to phenotype root traits in 286 soybean lines genotyped with 5.4 million single-nucleotide polymorphisms. There was a substantially higher correlation in manually counted number of root tips with computationally quantified root tips (95% correlation), when the background was cleaned of nonroot materials compared to root images without the background corrected (79%). Improvements in our RSA phenotyping pipeline significantly reduced overestimation of the root traits influenced by the number of root tips. Genome-wide association studies conducted on the root phenotypic data and quantitative gene expression analysis of candidate genes resulted in the identification of 3 putative positive regulators of root system depth, total root length and surface area, and root system volume and surface area of thicker roots (DOF1-like zinc finger transcription factor, protein of unknown function, and C2H2 zinc finger protein). We also identified a putative negative regulator (gibberellin 20 oxidase 3) of the total number of lateral roots.
