Beneficial effects of increasing dietary levels of raw lentil seeds on meat fatty acid and plasma metabolic profile in broiler chickens

Abstract

The aim of the present study was to investigate the effect of diets containing raw lentil seeds (Lens culinaris cv. Eston and cv. Anicia) on meat fatty acids profile and blood plasma parameters of broiler chickens. Day old, broiler chicks (1,000; Cobb 500) were randomly allocated to the following 5 treatments, viz. a diet based on corn and SBM as control; 200g/kg of raw lentil seeds cv. Eston (LE); 400 g/kg of LE; 200g/kg of raw lentil seeds cv. Anicia (LA);400 g/kg of LA. Data were analysed as a 2 × 2 factorial arrangement. The broilers meat fatty acid profile was affected by dietary inclusion of lentil. Accordingly, breast muscle of broilers fed raw lentil seeds had significant higher levels of alfa-linolenic, eicosapentaenoic (EPA), docosapentaenoic and docosahexaenoic (DHA) acids. A significant interaction was observed between level and cultivar for majority of n-3 PUFA profile, except for octadecatetraenoic acid, EPA and DHA. The blood plasma parameters were not influenced by treatments, except for glucose and triglycerides concentration which were lower in the groups fed with lentils. No significant interaction between lentil levels and cultivars was noticed for plasma parameters. Based on the results, we concluded that raw lentil seeds represent an interesting alternative protein source which can improve the quality of broiler meat that can be recommended in healthy, balanced diets to prevent human diseases.

Competitiveness and Advantages of <i>Camelina sativa</i> on the Market of Oil Crops

“…We have to note that competitiveness of crop production depends on a number of different factors, including elements of growing technology. Our research results are consistent with other literature data presented for Romanian, Canadian and Polish genotypes [Ciurescu et al, 2016;Krzyżaniak et al, 2019;Zając et al, 2020], while they provided higher rates in protein and fat, but slightly lower index in fiber for Italian genotype [Peiretti & Meineri, 2007]. Ciurescu [2016] observed similar protein, fat, and ash content to those found in our studies, but with lower fiber content (about 11%).…”

Ciurescu [2016] observed similar protein, fat, and ash content to those found in our studies, but with lower fiber content (about 11%). Zhang [2021] evaluated the quality of two Camelina sativa varieties grown under different climatic conditions in different locations of China and reported that protein and fat contents were in Obtained results on determining coefficients of energy, integral evaluation and complex coefficient of competitiveness showed that they change depending on the studied factors (Table 3).…”

The effects of dietary inclusion of Camelina sativa on performance and ascites incidence in broilers subjected to cold exposure

“…TA B L E 1 3 Effects of different sources and levels of Camelina sativa on ascites index (% of live weight) at day 42 and ascites mortality of broiler chickens during production period. The inclusion of different sources or levels of camelina in diets, except 2% CO, decreased growth performance in broilers, which are in agreement with former studies (Ciurescu et al, 2016;Thacker & Widyaratne, 2012). In contrast to our finding, Jaśkiewicz et al (2014) have reported that the inclusion of CO in the diet had no detrimental effect on broiler performance.…”

“…In contrast to our finding, Jaśkiewicz et al (2014) have reported that the inclusion of CO in the diet had no detrimental effect on broiler performance. Ciurescu et al (2016) also showed that diets with 5% CS or 2.5% CO did not have negative effect on broiler performance. However, BWG significantly decreased in birds that received a diet containing 10% CS.…”

“…The body weight, eviscerated carcass weight, abdominal fat and spleen weights declined in birds fed diets containing camelina sources. In the work of Ciurescu et al (2016), the inclusion of 2.5% CO and 5% CS had no negative effect on carcass characteristics. Although increasing, the level of CS from 5% to 10% significantly decreased abdominal fat in broilers, similar to our findings.…”
