By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

Environmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...

The effect of dietary calcium inclusion on broiler gastrointestinal pH: quantification and method optimization [PDF]

, 2014
There is little consensus as to the most appropriate methodology for the measurement of gastrointestinal pH in chickens. An experiment was conducted to establish the optimum sampling method for the determination of broiler digesta pH in birds fed ...

Surveying the Farmer Survey: A Synthesis of Research Practices in the Netherlands, Slovenia and Sweden

Journal of Agricultural Economics, EarlyView.
ABSTRACT Research based on farmer surveys is a cornerstone of agricultural economics. Farmer surveys provide unique insights into behavioural variables—such as values, motivations, attitudes, behaviours, and preferences—that are unavailable in secondary datasets.

Evaluating broiler welfare and behavior as affected by growth rate and stocking density

Poultry Science
: This study evaluated the welfare and behaviors of Cobb 700 broilers as affected by growth rate (GR) and stocking density (SD). Slower-growth (weight gain < 50 g/d) and medium-growth (weight gain = 50–60 g/d) broilers were produced by providing 57.1 ...

Virginiamycin and Broiler Performance

Poultry Science, 1984
Two experiments were conducted with broilers to determine the effect of Virginiamycin supplementation on performance and shank pigmentation. Virginiamycin supplementation at 10 ppm resulted in significantly increased body weights in both experiments.

Effects of Lactobacillus acidophilus on the growth performance and intestinal health of broilers challenged with Clostridium perfringens

Journal of Animal Science and Biotechnology, 2018
Clostridium perfringens is the main etiological agent of necrotic enteritis. Lactobacilli show beneficial effects on intestinal health in infectious disease, but the protective functions of lactobacilli in C.
