“…The lowest level of EEI was determined for the group fed the highest level of rape seeds but statistical analysis did not reveal any significant differences. The results of experiments on using full-fat rape seeds in broiler chicken feeding are diversified and they mainly depend on the amount of rape seeds incorporated into the diet [1,8,11,13,14,18,22,23]. Talebali and Farzinpour [23], feeding broilers for 6 weeks with mixtures containing relatively low levels (3-12%) canola seeds, did not note any differences in body weight gain.…”

“…One of them is the content of intact glucosinolates and also their degradation products, which may induce many metabolic disturbances [15,18]. Another factor responsible for worse performance results can be a lower apparent total and ileal digestibility of dry matter, protein, fat and, consequently, a lower apparent metabolizable energy value determined in diets containing 00-rape seeds [11,14]. Summers et al [22] report that feeding 17.5% full-fat canola seed to broiler chickens resulted in depressed fat use and body weight gain.…”

“…However, rape seeds contain nutritionally unfavorable substances such as glucosinolates, sinapin, tannin and phytate which may negatively influence many physiological processes and a health status by reducing the level of thyroid hormones, decreasing mineral absorption and changing the activities of liver enzymes in the blood of poultry [5,21,24]. The results of experiments on using full-fat rape seeds in broiler chicken feeding are diversified and they mainly depend on the amount of rape seeds incorporated into the diet [1,8,11,13,14,18,22,23]. According to some authors, the already low proportions of rape "00"seeds reduce the broiler performance data significantly, which is still more intensified with higher proportions of rape seeds in mixtures [7,18,23].…”

The aim of the study was to investigate the effects of different levels of rape "00" seeds in the diet on the performance, blood and bone parameters of broilers. A total of 180 1-day-old male Ross 308 chicks were divided into four groups. Group I (the control) was fed on a maize, wheat and soybean diet. Different levels of rape seeds were used in the experimental diets (low, medium and high level in II, III and IV groups, respectively) instead of a soybean meal. The amount of MJ AME N from rape seeds in total AME N was as follows: 0.19-1.51 group II, 0.28-2.26 group III and 0.38-3.01 group IV. The highest level of rape seeds resulted in a lower (P<0.05) body weight gain. The birds from group IV had the lowest feed intake and the poorest (P<0.05) value of FCR at 21 d. The highest level of rape seeds positively influenced (P<0.05) the content of HDL. There were no differences in protein metabolism indices, VLDL, Ca, Pi, bone resistance parameters among dietary treatments at 37 day of age. The results demonstrated that the influence of the increasing level of dietary rape seeds on performance, blood and bone parameters was much more evident in younger birds.

“…DM, energy and total carbohydrate utilization of no PKM diets were always higher than those of PKM diets. Poor utilization of the PKM diets could be attributed to NSP, which are poor in utilization in poultry digestive system (Meng et al, 2005). However, fat utilization was always higher in PKM diet compared to no PKM diet.…”

This study was conducted to evaluate the effect of dietary β-mannanase supplementation and palm kernel meal (PKM) inclusion (5%) on laying performance, egg quality and nutrient utilizability of laying hens with 73 weeks of age. A total of 240 Lohmann brown laying hens with average 77.5% egg production were randomly allocated with 60 hens per treatment, 4 replicates per treatment and 15 hens per replicate. Experimental design was a completely randomized design with 2 × 2 factorial arrangement, with the factors being (1) two levels of PKM (0 vs. 5%) and (2) with or without dietary β-mannanase (480 IU/kg of diet CTCzyme ® ) supplementation. All hens were housed in cages (35 cmW × 35 cmD × 40 cmH) with 2 hens per cage for six weeks feeding trial. Laying performance was recorded daily during feeding trial. Egg quality, nutrients utilizability and blood assays were done at the end of feeding trial. Egg production was improved (P<0.05) by both dietary PKM inclusion and β-mannanase combined supplementation. Either β-mannanase or PKM did not affect feed intakes and feed conversion ratio of all diets. Egg weight of hens fed diet containing 5% of PKM had heavier (P<0.05) eggs compared with hens fed without PKM. Albumen height was improved (P<0.05) by dietary mannanase supplementation. Crude fat utilization of 5% PKM diet was higher than that of no PKM diet regardless of β-mannanase supplementation. Both DM and total carbohydrate utilization were decreased (P<0.05) in hens fed 5% PKM diet. Serum IgG and yolk IgY contents of PKM groups were lower (P<0.05) than those of no PKM groups. This result showed that 5% PKM diet, independent of dietary β-mannanase supplementation, was able to improve egg production. In addition, dietary β-mannanase supplementation could be used for improving the albumen height of eggs.

“…However, the use of large amounts of vegetable feedstuffs in poultry diets is constrained by their high content of nonstarch polysaccharides (17.9% in CM vs. 14.5% in SBM) (4). Furthermore, broiler diets based solely on plant ingredients may increase the availability of dietary crude fiber level, which may suppress nutrient digestibility, affecting the birds' performance (5).…”
