The objective of this study was to obtain estimates of genetic and phenotypic parameters for egg mass of meat quails and also to propose an optimal age for selection of birds through the egg mass. The data used in this s...

Abstract Using a half-diallel model, six genotypes of bread wheat were crossed during 2021/2022 season, then in the next season of 2022/2023, parents and their F1 crosses were examined under optimum and late sowing dates...

The HMGA1 (High Mobility Group AT-hook 1) gene is considered a candidate locus for growth- and fatness-related traits in pigs due to its involvement in transcriptional regulation and energy metabolism and its localizatio...

ABSTRACT Aiming at breeding heifers with 14-15 months of age, 100 Hereford calves were subjected to different feeding systems. Heifers grazed on a natural pasture in early winter, fed or not a supplement (14% crude prote...

Identification of specific genetic markers that determine interbreed differences and “selection signatures” in commercial pig breeds will allow for the development of more effective strategies for targeted breeding a...

ABSTRACT The objective of this study was to demonstrate live weight estimation based on age by using Newton Interpolation method for male and female quails for seven weeks of fattening. A total of 138-day-old quail chick...

Nest survival is an important part of breeding success in grassland ecosystems, and the location of nests can determine vulnerability to different predators. We conducted an experiment with artificial nests to evaluate j...

A method to monitor seed germination that combines isothermal calorimetry and imbibition measurements is reported. Individual seeds of three cultivars of soybean seeds (A7636RG, Munasqa and DM5.8RR) and one of radish...

Abstract Bael (Aegle marmelos Correa), an underutilized fruit crop of high nutritional and medicinal value, exhibits wide adaptability to diverse agro-climatic conditions but remains neglected in systematic improvement a...

Abstract Durum wheat breeding increasingly requires tools that can anticipate how genotypes respond to the shifting mix of heat and drought typical of Mediterranean drylands. In this study, we explored whether a multimod...

Abstract Anardana, the dried arils of Punica granatum L., possesses notable culinary, nutraceutical, and medicinal value due to its richness in bioactive compounds. However, wild populations from the Himalayan belts rema...

Intensive technologies for breeding farm animals and poultry are largely determined by the balance of feeding diets based on essential substances. A certain shortage in the domestic feed market and insufficient control o...

Line breeding programs of autogamous crops like barley and wheat are characterized by multiple crosses with high variability in cross means and segregation variances. From theory of order statistics, we derived formulas ...

IntroductionThe African sugarcane stalk borer (Eldana saccharina) is a major insect pest of sugarcane in Sub-Saharan Africa. Because its larvae reside inside sugarcane stalks, conventional measures are less effective. Po...

The aim of this work was to map quantitative trait loci (QTLs) associated with flour yellow color (Fb*) and yellow pigment content (YPC) in durum wheat (Triticum turgidum L. var. durum). Additionally, QTLs affecting flou...

Application of modern methods of genetic testing allows to supplement traditional breeding with new ways of predicting economically useful qualities in animals. To improve the parameters of meat productivity in sheep of ...

BackgroundMango (Mangifera indica L.) is an economically important tropical fruit crop, yet the genomic diversity of mango germplasm from the Jazan region of Saudi Arabia—the country's primary production hub—remains ...

Several studies reported decreases in populations of Adélie penguins in the north and west of the Antarctic Peninsula. Thus, from 1994 to 2019 we studied the population trend of Adélie penguins at Hope/Esperanza Bay. F...

Se ensaya el cálculo de las distancias morfológicas para cuantificar el dimorfismo antropométrico sexual en distintas etnias aborígenes. Paralelamente se investiga: a- el grado de las diferencias entre los dimorfismo...

Brood reduction is a within-brood partial mortality due to sibling rivalry and has been observed in a large number of bird species from diverse taxa. Here, I summarize several hypotheses accounting for the adaptive value...

El objetivo del presente trabajo fue evaluar la incidencia de la edad y peso al primer servicio de cabrillas criollas de reposición sobre la productividad al primero y al segundo parto. Se registró: peso al nacimiento ...

Considerando que la evaluación de diferentes indicadores del estatus de cobre (Cu) en terneros con hipocuprosis permitiría mejorar el diagnóstico de riesgo de menores ganancias diarias de peso (< GDP), se buscó carac...

Se estudió la reproducción de la liebre europea -Lepus europaeus Pallas, 1778- en la Provincia de Buenos Aires, Argentina; durante un ciclo anual completo -1986/1987- y sobre un muestreo complementario -1988/1990-, con...

Se analiza la evolución del comportamiento reproductivo y se estima la probabilidad de actuación de la selección natural y la deriva genética en las subpoblaciones que conforman el Departamento Minas. Las pautas de r...
