To meet future world food and fiber demands, plant breeders must increase the rate of genetic improvement important agricultural crops. One biggest obstacles now facing crop scientists is a phenotyping bottleneck. ease this burden, emerging technology unmanned aerial systems (UAS) presents an exciting opportunity. assess utility UAS, it to investigate their application across multiple species. Terminal height great importance maize ( Zea mays L.) sorghum [ Sorghum bicolor (L.) Moench] has...
Phosphorus (P) fixation on aluminum (Al) and iron (Fe) oxides in soil clays restricts P availability for crops cultivated highly weathered tropical soils, which are common developing countries. Hence, deficiency becomes a major obstacle global food security. We used multi-trait quantitative trait loci (QTL) mapping to study the genetic architecture of efficiency explore importance root traits sorghum grain yield low-P soil. acquisition was most important component efficiency, both were...
Abstract Bovine semen cryopreservation is a fundamental procedure in animal reproduction. However, it associated with the production of reactive oxygen species (ROS), which can cause significant damage to spermatozoa, leading infertility and reduced sperm quality. In this context, using seminal diluents enriched antioxidants presents promising strategy for minimizing or even reversing these harmful effects. This study aimed evaluate effects different concentrations pequi (Caryocar coriaceum)...
Resumo A criopreservação de sêmen bovino é um procedimento fundamental na reprodução animal, mas está associada à produção espécies reativas oxigênio (ROS), que podem causar danos significativos aos espermatozoides. Esses estão relacionados infertilidade e diminuição da qualidade espermática. Nesse contexto, a utilização diluidores seminais enriquecidos com antioxidantes representa uma estratégia promissora para minimizar ou até reverter esses efeitos deletérios. O objetivo desse estudo foi...
In bioenergy/forage sorghum, morpho-anatomical stem properties are major components affecting standability and juice yield. However, phenotyping these traits is low-throughput, has been restricted by the lack of a high-throughput platforms that can collect both morphological anatomical properties. X-ray computed tomography (CT) offers potential solution, but studies using this technology in plants have evaluated limited numbers genotypes with throughput. Here we suggest medical CT might...
Abstract Aluminum (Al) toxicity damages plant roots and limits crop production on acid soils, which comprise up to 50% of the world’s arable lands. A major Al tolerance locus chromosome 3, AltSB, controls aluminum in sorghum [Sorghum bicolor (L.) Moench] via SbMATE, an Al-activated plasma membrane transporter that mediates exclusion from sensitive regions root apex. As is case with other known genes, SbMATE was cloned based studies conducted under controlled environmental conditions,...
Abstract: The objective of this work was to evaluate the quality pasture and enteric methane (CH4) emission Curraleiro Pé-duro x Nellore cattle in a Megathyrsus maximus 'Mombaça', both full sun consortium with babassu palms (Attalea spp.) Amazonian biome. experimental design completely randomized, six steers per system, evaluations were done during dry period (2015) rainy (2016). In comparison forage silvopastoral system showed, period, higher levels crude protein, ether extract, total...
The objective of this study was to assess genetic diversity among 5 Brazilian (155 animals) and U.S. goat (120 breeds using 23 microsatellite markers. Samples from the United States represented a broad geographic distribution whereas samples were northeast region. Boer common each country's breed count. Expected observed heterozygosity ranged 0.55 0.72, suggesting ample in evaluated. Angora, Spanish, Nambi ranked highest for allelic richness, averaging 6.1, 7.1, 6.5 alleles per locus,...
O objetivo neste estudo foi avaliar a diversidade genética entre 4 raças brasileiras (145 animais) e 15 bovinos norteamericanos (269 animais), utilizando 34 marcadores microssatélites. As amostras dos Estados Unidos representaram uma ampla distribuição geográfica, enquanto as foram da região centronorte. Os resultados mostraram que o grau de diferenciação estudadas indica baixo fluxo gênico populações analisadas, demonstra isolamento reprodutivo. Também é óbvia grande variação indivíduos...
The objective of this study was to evaluate live weight and carcass traits, from birth slaughter, meat quality Nellore (NEL), Curraleiro Pé-Duro (CPD), crossbred (F1) products in the state Piauí, Brazil. Progenies CPD, NEL, their F1 (½ NEL + ½ CPD), a total 252, males females, 24 months age, were evaluated comparative growth performance. steers sent slaughter at 28 age carcasses analyzed. After weight, dressing percentage Longissimus dorsi area (rib eye area) evaluated; an index created by...
Diseases cause enormous losses of yield and quality for crop producers worldwide. To meet future food demands, crops are bred resistance to as many these maladies possible. One such disease, anthracnose [Colletotrichum sublineola], is a fungal disease great importance sorghum [Sorghum bicolor, L. Moench] production because it causes significant annual economic in the crop. Breeding requires time-consuming phenotyping, which subjective conditional evaluator. It possible that quantitative...
Ethical and commercial issues are associated with animal welfare in pig farming, that sense, the objective of this work was to evaluate physiological blood parameters addition weight gain pigs raised without sunlight environmental enrichment (EE), as well correlate indicators. Twenty-four distributed a randomized block design 2 × factorial arrangement were used. Blocks represented by shifts (morning afternoon), factors presence or absence EE sunlight. Blood thermal comfort, gain, registered....
ABSTRACT Seminal plasma contains serine proteases and protease inhibitor, which are involved in mammalian fertilization, the inhibitors can be applied to prevent cold-induced sperm capacitation. The effects of different concentrations two were analyzed, Plasminogen activator inhibitor 1 - PAI-1 (70ƞg, 140ƞg 210 ƞg) Antipain (10µg, 50µg 100µg) as supplementation bovine semen cryopreservation extender. on parameters (sperm kinetics CASA, acrosome integrity, membrane mitochondrial potential,...
This study evaluated different crosses for sustainable beef production in the Meio-Norte, Brazil. Thirty-four cattle [seven Curraleiro Pé-duro (CPD), six Nellore (NEL), seven , and ] were on natural pastures states of Piauí Maranhão. The animals weighed at birth (BW); weaning (WW); 12 (W12), 18 (W18), 24 months (W24); slaughter (SW). morphometric measurements rump height (RH), withers (WH), body length (BW), heart girth (HG) [...]
Cryptosporidiosis is a parasitic disease caused by protozoan from the genus Cryptosporidium with cosmopolitan distribution and zoonotic potential. The objective of this work was to determine occurrence helminthosis in Santa Ines sheep herd during dry rainy season. This developed at sheep’s breeding sector Federal University Piaui, located Southern Piauí, Brazil. Fifty kept semi-intensive system were used experiment using method according Ritchie, Ziehl-Neelsen Gordon Whitlock. oocysts...
O experimento foi conduzido com o objetivou de avaliar os efeitos antioxidantes da adição do eugenol no diluidor TRIS-gema para a criopreservação espermatozoides bovino.Foram utilizados vinte ejaculados quatro bovinos Curraleiro Pé-Duro, após as coletas sêmen diluído em TRIS-Gema e dividido três alíquotas; contole, tratamento nas concentrações 10µM 50µM eugenol.Posteriormente amostras foram envasadas palhetas 0,25ml criopreservadas.Em seguida mantidas equilíbrio por 60 minutos 5ºC, então...
