Influence of broiler strain cross and dietary protein on the performance of broilers

Poultry Science, 1998
The purpose of this experiment was to quantify the responses of two broiler strain crosses to different dietary protein levels on performance and carcass yields. Day-old broiler chicks from a high-yield strain cross (Ross x Ross 208) and a fast-growing strain cross (Peterson x Arbor Acres) were placed in floor pens on fresh pine shavings.

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.

Cointegration analysis of broiler meat and broiler feed prices in Turkey

Eurasian Journal of Veterinary Sciences, 2019
Aim: The high share of feed costs among the costs of inputs used in broiler breeding plays a significant role in the formation of broiler meat price. As the production of raw materials used in the broiler feed industry is not sufficient to meet the demand in the domestic market, the demand is met by importation.

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.

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

Integrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

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

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

Variability in wheat: factors affecting its nutritional value

, 2008
Wheat is a common raw material used to provide energy in broiler diets. Its apparent metabolisable energy and its influence on broiler performance varies between wheat samples.

Extrusion and Pancreatin Superdosing Modulate the Metabolic Impact of 20% Chlorella vulgaris Inclusion in Broiler Diets

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Microalgae such as Chlorella vulgaris are gaining attention as sustainable and nutritionally valuable feed ingredients, with the potential to partially replace soybean meal in broiler diets. However, dietary inclusion of 20% C. vulgaris has been attempted, but negatively affected growth performance due to limited digestibility.

Effects of Broiler Breeder Age on Egg Quality, Incubation Performance, and Early Progeny Physiological and Muscle Fiber Development

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study evaluated the effects of breeder hen age on the incubation performance, embryonic development, and progeny quality of Cobb500 broiler breeders at 39, 51, and 69 weeks of age. A total of 870 eggs were collected, of which 810 were incubated; these were assigned to a completely randomized design with three treatments and nine ...
