1. The aim of the study was to investigate the effects of feeding fast growing turkeys with differentiated dietary calcium (Ca) content, and the partial replacement of vitamin D(3) in the feed with 25-hydroxycholecalciferol (25(OH)D(3)), on skeletal properties. 2. One-day-old Big-6 male turkeys (n = 1008) were randomly divided into 4 groups, and two subgroups were created within each group. The groups were differentiated with 4 levels of Ca provision in the feed, namely 85% of the National Research Council ( ...

The nutritive value of meals derived from black- and yellow-seeded Brassica napus and canola-quality Brassica juncea was determined with broiler chickens and young turkeys. A higher apparent ileal digestibility of total amino acids was observed in chickens fed diet containing yellow-seeded B. napus than in those fed conventional black-seeded B. napus or canola-quality B. juncea (88.8 vs 83.4 and 84.2%, P < 0.05).

The aim of this experiment was to investigate the physiological and growth response of young turkeys (up to 8 weeks of age) to dietary replacement of soybean meal (SBM) by soy protein concentrate (PC) or protein isolate (PI). This replacement resulted in a differentiated dietary concentration of α-galactosides of over 2.5% in the SBM diet, approximately 2% with a mixture SBM and PC, 1% with a PC diet and 0.1% with a PI diet. Each treatment was applied in two ways: with lower (3.5%) or higher (5.3%) dietary ...

Fruit pomaces are by-products rich in polyphenol compounds and dietary fiber. They seem to play an important role in regulating the gut microbiota, morphology and physiology. The aim of this study was to assess whether apple (A), blackurrant (B) or strawberry (S) pomaces could be suitable ingredients in broiler diets and their effect on gut health. A total of 480 male broilers were randomly allotted to 8 dietary treatments with lower (3%-L) or higher (6%-H) dietary fiber content: two control groups (CL/ ...

The hypothesis of the research was the assumption, that manganese nanoparticles can affect the body in the same way as macromolecules. Their smaller size and greater biological reactivity will potentially allow the Mn addition to the diet to be reduced and, consequently, less excretion of this element into the environment. The aim of the study was to determine whether the use of Mn nanoparticles would make it possible to reduce the level of this micronutrient added to turkey diets without adversely ...

Postileal fermentation in the gastrointestinal tract of poultry takes place as a result of the interaction between two components of the intestinal ecosystem: rapidly changing microbiota and digesta with different physicochemical properties. Short chain fatty acids, the major products of fermentation, act to stabilise microbiota composition and maintain gut health, and constitute an additional source of energy. Due to different mechanisms of action of probiotics, phytobiotics and prebiotics in the ...

In comparison with soybean, lupine seeds had a higher content of neutral detergent fiber (NDF) and raffinose family oligosaccharides (RFOs) (25.4% vs. 9.61% and 7.98% vs. 5.91%). The dietary 20% lupine seeds increased ...

Abstract Functional foods, defined as “foods that may provide health benefits beyond basic nutrition”, became increasingly popular in the past twenty years with numerous practical applications. In Europe, functional foods must be accompanied by scientifically substantiated health claims. Products which aspire to that category include poultry meat and processed meat products which have been modified through bird nutrition. This article reviews the existing knowledge about foods fortified with health- ...

Abstract Background Haemorrhagic enteritis (HE) of turkeys was first described in 1937 in the USA, while in Poland it was first diagnosed in 1987. Polish haemorrhagic enteritis virus (HEV) isolates are usually low pathogenic and trigger a subclinical disease. Unfortunately, even the low- pathogenic HEV strains cause severe immunosuppression leading to secondary bacterial infections and huge economic losses. The objective of this study was to evaluate if the influence of Met on HEV infected turkeys ...
