this study was conducted to investigate the effects of garlic powder (gp) black seed (bs) and plant premix (gp and bs) in the diet on broiler growth performance and intestinal morphology. included 480 hubbard broiler chicks(day-old). there were 4 treatment groups each consisting of 3 replicates. the four dietary treatments consisted of a control (basal diet), basal diet +0.5% gp, basal diet +0....

this experiment was conducted to evaluate the ability of silybum marianum seeds (sms) on performance, carcass variables, and liver morphology of the broiler chickens contaminated with aflatoxin b1 (afb1). a total of 216 broiler chicks (ross 308) were used. birds were randomly assigned to nine treatment groups, with four replicates and six birds in each replicate. chickens were reared on litter ...

It is generally accepted that larger seeds give rise to seedlings with better performance. On the other hand, the size that a seed reaches is genetically determined by at least two different traits ; the genetic variability of the developing embryo and the genetic variability of the maternal plant. Thus, the relative contributions of these two traits affect seedling performance by influencing s...

The performance of seed tubers harvested from potato plants grown from sprout cutting, stem cutting and conventional seed tubers against PVY and PLRV were investigated. Sprout cutting, stem cutting and conventional seed tubers of variety Diamant were planted and second and third generation seed tubers were harvested. The least incidence of PVY and PLRV was recorded when seed tubers from sprout ...

> Seed systems are crucial for sustainable food system outcomes: agricultural sustainability, food security and healthy diets. > Production and distribution, innovation and regulation are the key functions of seed systems, which make a difference to sustainable food systems. > Currently used methods to measure the performance of seed systems concentrate narrowly on their contribution to agricul...

Seed performance after dispersal is highly dependent on parental environmental cues, especially during seed formation and maturation. Here we examine which environmental factors are the most dominant in this respect and whether their effects are dependent on the genotypes under investigation. We studied the influence of light intensity, photoperiod, temperature, nitrate, and phosphate during se...
