Protein hunger of the feed sector: the alternatives offered by the plant world Ital. J. Anim. Sci. (IF 1.805) Pub Date : 2020-10-12 Giuliana Parisi; Francesca Tulli; Riccardo Fortina; Rosaria Marino; Paolo Bani; Antonella Dalle Zotte; Anna De Angeli; Giovanni Piccolo; Luciano Pinotti; Achille Schiavone; Genciana Terova; Aldo Prandini; Laura Gasco; Alessandra Roncarati; Pier Paolo Danieli
Abstract The expected future demand for highly nutrient animal food products will push the animal production system to search for new sources of high-quality protein feedstuffs. In this scenario, economic and environmental issues will have to be considered while reducing the competition with the plant-based human food chains. Legume grains and some oilseed cakes, by-products from the oil industry,

Effect of does parity order on litter homogeneity parameters Ital. J. Anim. Sci. (IF 1.805) Pub Date : 2020-10-06 Marta Pollesel; Marco Tassinari; Andrea Frabetti; Daniela Fornasini; Damiano Cavallini
Abstract In rabbits’ reproductive performance, litter size, birth weight, growth, and mortality rate are among the most important indicators to define the productive potential and they are associated with parity order. Birth weight and little size are valuable parameters as related to mortality and weaning weight. Thus, it is important to study individual newborn and intra-litter homogeneity parameters

Abstract Animal welfare assurance is of great importance as dairy farming is recently under increasing pressure to meet societal and commercial expectations. Therefore, this study aims to determine the current welfare situation of dairy cattle housed in tie-stalls and free stalls in South Tyrol (Eastern Italian Alps) in order to evaluate the need for establishment of an animal welfare assurance programme

Dietary supplementation with sodium butyrate: growth, gut response at different ages, and meat quality of female and male broiler chickens Ital. J. Anim. Sci. (IF 1.805) Pub Date : 2020-09-29 Antón Pascual; Angela Trocino; Marco Birolo; Barbara Cardazzo; Francesco Bordignon; Cristina Ballarin; Lisa Carraro; Gerolamo Xiccato
Abstract The present study aimed to evaluate how dietary supplementation with a microencapsulated sodium butyrate (500 mg/kg; 30% Na-butyrate) in 768 male and female broiler chickens affected growth performance, jejunum gut morphology and caecal microbiome at different ages (11, 24, and 35 d), slaughter results, meat quality, and myopathy (white striping, wooden breast, and spaghetti meat) occurrence

Comparative assessment of sodium selenite, selenised yeast and nanosized elemental selenium on performance response, immunity and antioxidative function of broiler chickens Ital. J. Anim. Sci. (IF 1.805) Pub Date : 2020-09-25 Amirarsalan Pardechi; Sayed Ali Tabeidian; Mahmood Habibian
Although selenium (Se) supplementation is a common practice in poultry, the best source and level has not been established yet. Thus, a 42-day experiment involving diets with three levels (0.1, 0.2 and 0.5 mg/kg) of supplemental Se from sodium selenite (SS), selenised yeast (SY) and nanoelemental Se (SN) was conducted to evaluate the possible differential responses of broiler chickens to inorganic

Efficacy of dietary supplementation of nanoparticles-chromium, chromium-methionine and zinc-proteinate, on performance of Japanese quail under physiological stress Ital. J. Anim. Sci. (IF 1.805) Pub Date : 2020-09-25 Arash Barzegar Yarmohammadi; Seyed Davood Sharifi; Abdollah Mohammadi-Sangcheshmeh
The effects of dietary Nanoparticles-Chromium, Chromium methionine, and Zinc-proteinate on performance, blood characteristics and meat quality of physiologically stressed quails were studied. The stress was induced by adding dexamethasone (0.6 mg/kg BW) to diet when quails were between 17 and 22 days of age.

This study was aimed at investigating the effect of water deprivation levels on intake, growth performance and nutritional status of Nguni goats. Thirty-six Nguni goats (initial weight, 18 ± 3.2 kg) were assigned
