Relevance of Water Quality to Broiler and Turkey Performance

Poultry Science, 1996
Water was tested from 300 broiler farms in Arkansas in cooperation with three integrated poultry companies, each having at least two locations in the state. The turkey study was conducted in cooperation with three integrated turkey companies with samples from 100 turkey farms, although the numbers were not equal among companies.

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

Wildlife Monographs, EarlyView.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

Evaluation of Ammonia Stress and Coccidiosis on Broiler Performance

Poultry Science, 1979
Eighty broiler chickens were randomly assigned to each of 12 chambers in a controlled environment poultry facility. Ammonia gas was injected at 0, 50, or 100 ppm from 28 to 53 days of age. All chicks, except the control pens, were innoculated with coccidia at 36 days of age.

Uncovering Biogas Outcomes: Tales of Hubris, Hope, and Failure From Southern Malawi

Natural Resources Forum, EarlyView.
ABSTRACT The purpose of this article is to speak directly to biogas failure. Over the past two decades, immense amounts of money have been spent by African governments, private individuals, and most conspicuously, international aid agencies and donors, on countless biogas projects in every country on the continent.

Effect of Dietary Fructose on Broiler Chick Performance

Poultry Science, 1987
The effect of feeding various levels of dietary fructose, furnished by high fructose corn syrup (HFCS), to broiler-type chicks housed in Petersime batteries was studied in two experiments. In experiment 1, HFCS was added to a corn-soybean meal basal diet at levels of 0, 5, 10, and 15%. In Experiment 2, HFCS was added to the diet at levels of 0, 2, 4, 6,

Antimicrobial Use in Livestock: The Economic Cost of Action or Inaction

Journal of Agricultural Economics, EarlyView.
ABSTRACT This paper quantifies the economy‐wide consequences of two independent global stress‐tests in livestock production. The first assesses the effects of phasing out antimicrobial growth promoters (AGPs), and the second evaluates the long‐term impacts of antimicrobial resistance (AMR) progression.

The effects of high-air velocity on broiler performance

Poultry Science, 2003
Two trials using a total of 1,484 Ross male broilers were conducted to study the effect of air velocities of 180 and 120 m/min versus still air (

Haematological and histopathological monitoring of monosodium glutamate–supplemented feeding in rainbow trout (Oncorhynchus mykiss): A possible modelling for a single health approach

Journal of Fish Biology, EarlyView.
Abstract The aim of this study was to investigate the potential effects of monosodium glutamate (MSG), a known flavour enhancer added to many ready‐to‐eat foods, as a feed additive in rainbow trout (Oncorhynchus mykiss). Evaluating the effects of MSG on aquatic organisms will fill the knowledge gap in this field by monitoring the haematological indices

Influence of Dietary Supplementation with Yeast Culture and Microencapsulated Butyric Acid on Growth Performance, Carcass Traits, Gut Health, and Immune Status in Broilers

Veterinary Sciences
The study aimed to examine the effects of dietary supplementation with microencapsulated butyric acid (EBA) and yeast culture (YC) in broiler diets. A total of 450 Ross-308 broiler chicks were selected and randomly allocated to five dietary treatments ...

Feeding Laboratory Mice: Comparing a Standard Versus a Purified Diet – Marked Effects on Digestive Physiology

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Diet composition and processing have a major impact on its utilisation by the animal, as is known from farm and pet animal species. This includes effects on energy and nutrient digestibility, the intermediary metabolism, and the intestinal microbiome, with all the resulting impacts. For laboratory animals, data is scarce on influencing factors
