Based on the materials of the National Corpus of the Russian language, the specific character of their functioning in the Russian speech is revealed.

It includes lexicographical, etymological, and semantic analysis of words; identification of their syntagmatic and paradigmatic relations, features of adaptation in the host language and use in its different functional varieties, frequency of use; the role of borrowings in the lexical system of the Russian language. The research is based on the study of the lexis of Arabic origin.

Research paper thumbnail of Effect of energy to protein ratio using alternative feed ingredients on growth performance and nutrient digestibility in broilers

A total of 160 one-day old broiler chicks were divided randomly to four groups and each group had 8 replicates with 5 chicks per replicate. The control diet was formulated using conventional feed ingredients with EPR of 154 for the starter period and 167 for the finisher period. The other treatments were diets with normal, low, and high EPR (154,143, and 166 for the starter period; 167, 155, and 177 for the finisher period) using FWBSFL. Feed consumption and body weight gain as well as digestibility of crude protein, crude fiber, and fat were decreased due to feeding of FWBSFL diets. Different levels of EPR using FWBSFL decreased growth performance and nutrient digestibility of broilers.

The BSFL contained a high percentage of protein (559.9 g kg −1), metabolizable energy (696.3 kcal kg −1), crude fat (18.6 g kg −1), and dry matter (178 g kg −1) and a good balance of amino acids. A total of 54 Arabic strain hens at nine months of age were mixed with nine cocks at 12 months old; all were divided into three treatments. The diets were formulated based on three levels of energy-toprotein ratio: 155, 140, and 170. The BSFL meal was added at 0, 50, and 10 g kg −1 respectively. The results showed that feed intake, weight gain, Haugh unit, and hatchability were not affected by dietary treatments with BSFL. However, there was significant improvement in hen day egg production and hen house egg production due to dietary treatments of BSFL. Also, feed conversion ratio, egg weight, shell thickness, shell weight, egg yolk color, fertility, and egg mass were affected by dietary treatments. In addition, a significant improvement was observed in appearance, texture, taste, and acceptance of eggs of hens fed BSFL at 50 g kg −1. The odor was not affected by dietary treatments. Black soldier fly larvae can be a good source of protein in layer diets.

One hundred twenty Cobb500 broiler chicks were randomly assigned to four diets. Corn, soybean meal and fish meal were replaced with rice waste, meat and bone waste and black soldier fly larvae (BSFL) at 0, 10, 30 and 50% to form four treatments. Body weight gain, feed conversion ratio and digestibility of crude protein and fat were improved in broilers fed the replacement diets. Feed intake was not affected by the treatments suggesting that the replacement diets were well accepted by the chicken. Escherichia coli was decreased in the cecum and Lactobacillus were increased in the intestines of broilers fed the replacement diets. The fiber and chitin contents in the replacement diets may alter intestinal bacterial fermentation leading to improved nutrient digestibility. Howe...
