“…However, SGPT has poor specificity for liver disease in birds due to its existence in many tissues. Our results of SGOT activity (157.5 to 159 U/L) in GF were low compared to results in chickens of Wang et al ( 2017 ) (174 to 190 U/L). SGPT activity (3.1 to 3.5 U/L) in GF was in the range of results of these authors (1.83 to 3.17).…”

Effect of Hevea brasiliensis seed meal or Euphorbia heterophylla seed supplemented diets on performance, physicochemical and sensory properties of eggs, and egg yolk fatty acid profile in guinea fowl (Numida meleagris)

A total of 144 French selected breed (Galor) female guinea fowl (GF) of 42 wk of age were enrolled for a feeding trial of 15, 30, and 45 D duration. The birds were randomly assigned to 18 cages, each containing 8 birds. A total of 3 isonitrogenous and isocaloric dietary treatments were trialed, each diet comprising 6 replications (cages), which meant a total of 48 birds per diet. The GF were fed either a control diet C (commercial diet “FACI ponte 20”, SIPRA, Ivory Coast, usually used for all poultry species) or the diet C supplemented with 5% Euphorbia heterophylla seeds (diet E) and the diet C supplemented with 5% Hevea seed meal ( Hevea brasiliensis ) (diet H). Animal performance were assessed for 3 periods (days 0 to 15, 0 to 30, and 0 to 45), and egg quality and composition were assessed at 15, 30, and 45 D of the trial. The results indicated no mortality during the trial. The laying rate was the highest (43.9%) with diet E and the lowest with diet C (32.5%), the laying rate with diet H being intermediate (38.5%). Diet E containing Euphorbia seeds led to a reduced cholesterol content of the eggs. Additionally, inclusion of Euphorbia seeds and, to a lesser extent, of the Hevea seed meal in the diet led to n-3 polyunsaturated fatty acid enriched GF eggs, with thereby, improved nutritional value. A sensory test did not find any difference between the 3 diets on trial.

“…It is well established that the protein content of the egg is highly influenced by the diet of the hen ( Wang et al., 2017 ). Although most likely the chickens that laid the eggs for this study had access to very different feeds, no differences were found in the protein content of the albumen between eggs laid by the different breeds of chickens.…”

A comparison between the quality of eggs from indigenous chicken breeds and that from commercial layers

et al. 2020

There is an increased interest in animal products from more sustainable farming practices, which may include using local breeds. In addition, maintaining biodiversity is important, and naturally, indigenous breeds of chickens are well adapted to the local environmental conditions. In the current study, 286 eggs from 4 Portuguese breeds of chickens (Branca, Amarela, Pedrês Portuguesa, and Preta Lusitânica) and from a commercial hybrid laying hen were used. Chemical and physical characteristics of the eggs and the egg components such as weights, Haugh units, yolk color, albumen protein content, yolk fatty acid content, and mineral content in the albumen and yolk were analyzed. The Branca breed produced eggs with a lighter brown shell color and lower Haugh unit values than the remaining native breeds ( P < 0.05). The commercial hens produced eggs that were found to be more rounded shape than the ideal and with a darker colored shell and yolk than eggs from the 4 local breeds. In addition, the commercial hens also produced heavier eggs but with lower Haugh units than the Amarela, Pedrês Portuguesa, and Preta Lusitânica breeds ( P < 0.05). The range of saturated fatty acids, monounsaturated fatty acids, and total polyunsaturated fatty acids between eggs from the 4 breeds was small and not significantly different. No differences were found in the percentage of albumen protein between breeds. Albumen and yolk ash content was not different between breeds. The overall analysis indicated that eggs from these native genotypes match the quality of a commercial product in many characteristics. In markets where eggs from local breeds are available, consumers are purchasing a high-quality product while aiding in the expansion of local genetic resources and investing in local farmers.

“…Disparate results on albumen quality were presented by Gheisari and Ghayor [ 42 ], in which eggs obtained from quail fed a mixture containing 15% canola meal were characterized by a significantly better quality of this morphological element, while the best albumen quality characterized eggs from birds fed with 20% canola meal addition. A slightly different observation was made by Wang et al [ 2 ], who analyzed the quality of eggs from hens fed various alternative protein sources (including rapeseed meals). It was found that eggs from birds fed with rapeseed meals were characterized by lower quality compared to those fed with a standard feed mixture (based on soybean meal).…”

“…Protein is one of the most important balanced components of poultry feed and the source of essential amino acids. Its quality is crucial for the proper growth and good health of birds, their production and the quality of obtained eggs [ 1 , 2 ]. Currently, soybean meal is a major protein source in poultry nutrition.…”

The most popular protein source in poultry feed mixtures is soybean. However, cheaper and more available alternative protein sources are being sought, and feed manufacturers more and more often turn their attention to the post-extraction meals of local oil plants, e.g., rapeseed. Therefore, the effect of fermented and non-fermented post-extraction rapeseed meal used as a feed additive for Japanese quails was investigated on the eggs’ quality. The study was performed on 280 females of Japanese quails fed with a mixture without rapeseed meal, with non-fermented post-extraction rapeseed meal (5%, 10% and 15%) and with fermented one (5%, 10% and 15%). During the experiment, eggs were collected from each group four times (every 4 weeks) and evaluated for their quality characteristics. The addition of 10% fermented rapeseed meal had the most beneficial effect on such eggs quality traits as egg weight, specific gravity, yolk index and color and albumen pH. However, in the majority of examined parameters, no significant differences were found between birds fed with soybean meal and those fed with fermented and non-fermented rapeseed meal (morphological elements proportions, yolk weight, albumen height and Haugh’s units, eggshell quality). This supports the thesis that the use of rapeseed meals instead of soybean meals may allow obtaining the proper quality of animal raw materials at a lower cost and with the use of local feed resources.
