Effect of crude fibre additives ARBOCEL and VITACEL on the physicochemical properties of granulated feed mixtures for broiler chickens.

Objective: The aim of the study was to evaluate the physicochemical properties (nutrient composition, pH, water content and activity, sorption properties) and mechanical properties (compression force and energy) of granulated feed mixtures with various inclusion levels of crude fibre concentrates ARBOCEL and VITACEL for broiler chickens, i.e. +0.

Selenium and the health status, production results, and product quality in poultry.

A Selenium (Se) is an element belonging to the nonmetallic group. It was first discovered in 1817 by J.J.

The Effect of the Size of the Litter in Which the Sow Was Born on Her Lifetime Productivity.

Improvement of lowly heritable traits is difficult, efforts must be made to take full advantage of the available information sources to improve them. The objective of the study was to determine the effect of the size of the litter in which the sow was born on her lifetime reproductive performance. Data on 22,683 litters were used to analyse the lifetime reproductive performance of 5623 Polish Large White sows.

Alternative Protein Sources vs. GM Soybean Meal as Feedstuff for Pigs-Meat Quality and Health-Promoting Indicators.

This study aimed to explain the possibility of partial replacement of genetically-modified soybean meal (SBM GM) with pea seeds and rapeseed meal (RSM) in complete feed mixtures for growing-finishing pigs and to determine its impact on meat quality and health-promoting indices. The pigs (n = 50) were randomly divided into five groups, 10 animals each (gilts and barrows, 1:1, 3-breed: ♀ (landrace × yorkshire) × ♂ duroc), including the control group (C) and four experimental groups (E1, E2, E3, E4), and fed complete feed mixtures. The SBM GM was the only protein source in feed mixtures for control pigs.

Performance Results and Concentrations of Biochemical Indices and Mineral Elements in Blood Serum of Fatteners Fed Diets Containing Mixtures of Raw Seeds of Pea ( L.) or Blue Lupin ( L.).

Two experiments were conducted with fatteners (♀ (Landrace × Yorkshire) × ♂ duroc), 50 animals each (10 pigs per group). The fatteners from the control group (C) were administered feed mixtures with genetically modified soybean meal (SBM-GM) used as the only protein source; whereas these from experimental groups (E1-E4) received feed mixtures in which the SBM-GM was replaced with increasing amounts of raw seeds of pea (Experiment I) or blue lupin (Experiment II): E1-5.0%, E2-10.
