A total of 1947 farms from the Pomerania and Kujawy regions were analysed for the effect of type of pen (with or without litter) on the cytological quality of milk, taking into account the season of the year in the statistical calculations. It was found that in most barns, cows were kept in shallow litter stalls. Regardless of the season of the year, milk of the highest cytological quality was ...

litter size is one of the most important economical traits in sheep breeding industry. in addition to minor genes, litter size is under the influence of major genes. bone morphogenetic protein 15 (bmp-15), a member of the transforming growth factor beta (tgf-ß) superfamily, which is specifically expressed in oocytes, plays a dramatic role in sheep prolificacy. reported mutations in this gene ca...

The research work was conducted to detect and characterize of Escherichia coli and Salmonella found in the poultry feed and litter. A total of 48 samples were collected from the different Broiler farms of Dinajpur district and brought to the laboratory. Samples were propagated in nutrient broth and nutrient agar media followed by culture on selective media– Eosin Methylene Blue Agar, MacConley ...

Samples of leaf litter were collected from 22 woodland sites throughout Prince Edward Island, Canada. Eighty-two specimens belonging to 15 species litter-dwelling land snails recovered 20 the samples. One-third species— Carychium exile H.C. Lea, 1842, Helicodiscus shimeki Hubricht, 1982, Strobilops labyrinthicus (Say, 1817), Perpolita binneyana (Morse, 1864), and Striatura ferrea Morse, 1864—we...

this experiment was conducted to determine the effects of sodium bentonite litter supplement and stoking density on performance and litter quality using a total of 252 broiler chicks in completely randomized design with 6 treatments which were arranged factorially (3×2) and 4 replicates. experimental factors included: stocking density (14; low and 18; high /birds per m2) and three levels of sod...

abstract the addition of manures and chemical fertilizers as soil amendments for the improvement of soil fertility and quality could affect the seasonal changes in the activity of soil microbes and enzymes. this study aimed at investigating the effect of different levels of nitrogen from broiler litter and urea sources on the trend of urease, alkaline phosphatase and saccharase activities in a ...

specific features of the structure of the ground litter invertebrate community in forest belt ecosystems in the ukrainian steppe zone have been considered. for 14 years invertebrate fauna of the litter of 176 forest belt sites with different composition has been studied with the aid of soil traps. the main characteristics of litter invertebrate communities (total population, a number of species...
