Effectiveness Evaluation of Use of Various Protein Feeds for Broiler Chicken Feeding

Abstract

The purpose of this paper was to assess the suitability of various protein feeds in broiler chicken feeding. The study covered 160 birds split into 5 equipotent groups (SBM, EFFS, RFFS, EL, DDGS). Four protein feeds were an experimental factor: extruded full-fat soybean (EFFS group), raw full-fat soybean (RFFS group), extruded lupine (EL group) and distillers dried grains with solubles (DDGS group) that were added to starter rations in an amount replacing 30%, and in grower and finisher rations 50% of extracted soybean meal protein. Results showed that after replacing an identical amount of extracted soybean meal protein with protein from extruded soybean or DDGS in chicken rations, the final body weight and feed conversion ratio were similar to those of birds from the control group. Deterioration (P≤0.01) in the above-mentioned parameters was observed for chickens fed with rations containing raw soybean or extruded lupine. Birds that were given rations containing raw soybean (RFFS group) were characterized by the lowest dressing percentage, and, compared to the control group, the difference was significant (P≤0.01). The type of protein feed contained in the rations did not affect the musculature of chickens, however it did impact their fat deposition. Fat deposition was the lowest in birds from RFFS and DDGS groups that reached the lowest final body weight. Microscopic images of all examined livers showed a normal histological structure. The results of the studies carried out provide a basis for recommending the use of extruded full-fat soybean or DDGS in broiler chicken rations as partial substitutes for extracted soybean meal protein.

Slaughter value and meat quality of broiler chickens fed with rations containing a different share of pea seed meal

“…On the other hand, a* and b* are trichromatic coordinates, where a* as a positive value corresponds to red, and as a negative value -green; in turn, positive b* corresponds to yellow, and negative b* -blue. The colour parameters a* and b* were applied to calculate chroma (C) and hue (H) with formulas used by Milczarek and Osek (2019).…”

“…The main anti-nutrients in pea seeds are inhibitor trypsin and chymotrypsin as well as tannins (Osek et al, 2013). The seeds of legumes, at the level of both plant species and variety, have a diverse chemical composition, so it is necessary to carry out studies aimed at determining the efficiency of their use in feed rations for various species and production groups of poultry Laudadio et al, 2012;Milczarek et al, 2019;Moschini et al, 2005;Osek et al, 2013;Usayran et al, 2014). Pea seeds are characterised by a lower content of total protein and the highest level of metabolic energy among the seeds of legumes (Czerwiński et al, 2010;Laudadio and Tufarelli, 2010;Osek et al, 2013).…”

“…A significant share of the feed on the worldwide market is constituted by GMO varieties from South American countries and the USA (Davison and Ammann, 2017). In this context, alternative sources of feed protein of plant origin are sought (Biesek et al, 2020;Hejdysz et al, 2017;Milczarek and Osek, 2019;Niwińska et al, 2019). Developing the cultivation of legumes,…”

The Quality of Carcass and Meat from Geese Fed Diets with or without Soybean Meal

“…In the past, the use of lupins in livestock diets was limited by high levels of alkaloids, tannins, and non-starch polysaccharides (NSPs), which reduced palatability, nutritional value, and feed intake [7][8][9][10]. New varieties of lupin, however, created as a result of breeding studies, are characterized by a lower content of anti-nutritional ingredients and no longer have such drawbacks [11][12][13][14][15].…”

Effect of Soybean Meal Substitution by Raw Chickpea Seeds on Thermal Properties and Fatty Acid Composition of Subcutaneous Fat Tissue of Broiler Chickens

“…The tendency to reduce the use of feed containing GMOs (genetically modified organisms), and the growing customer preferences for animal products obtained from animals not given such feeds, increase the need to look for alternative sources of dietary protein. Previous studies indicate that alternatives to SBM can be faba bean [7,8], lupines [9][10][11], chickpeas [12,13], and, as it was found more recently, nonplant protein sources such as insect meal [14][15][16]. As compared to soybean, chickpea seeds (CPS) are characterized by a lower content of chymotrypsin and trypsin inhibitors, while the nutritional value of chickpea protein is comparable to that of soybean [17].…”
