“…Siregar et al (1982) also reported that feeding White Pekin ducklings the increased amounts of DF resulted in the reduced carcass fat content. Gonzalez-Alvarado et al (2010) reported that the inclusion of oat hulls did not affect the yield of valuable parts (pectoral and leg quarters) in broiler chickens. Jorgensen et al (1996) pointed out that the increase of the insoluble fibre content in the diet often results in a decrease in carcass yield in broiler chickens.…”

The objective of this study was to evaluate the responses of growth performance, organ development, carcass characteristics, and serum biochemical parameters to the diets with different levels of crude fibre (CF) in growing male China Micro-ducks (CMD). A total of 240 nineteen-day-old CMD were blocked on the basis of body weight, and then randomly allocated to four treatments, each with 6 replicate pens of 10 ducklings. The formal feeding experiment lasted for 35 days. The CF levels for four diets were 16.7, 42.6, 77.9, and 101.6 g/kg of dry matter (DM), respectively. The diet with the CF level of 101.6 g/kg of DM resulted in the first-rank growth performance, followed by the diets with the CF level of 42.6 and 77.9 g/kg of DM, and then the diet with the CF level of 16.7 g/kg of DM. The diet with the CF level of 42.6 g/kg of DM led to the optimum slaughter performance, followed by the diets with the CF levels of 16.7 and 77.9 g/kg of DM, and then the diet with the CF level of 101.6 g/kg of DM. With the increase of the CF level in the diets, the serum glucose concentration and the relative weights of proventriculus and gizzard significantly rose (P < 0.05), but the serum concentrations of low-density lipoprotein cholesterol and creatinine, the percentages of head, feet, and abdominal fat, and the relative weights of liver, jejunum, and ileum significantly decreased (P < 0.05). For the percentages of pectoral muscle and lean meat and the relative weight of thymus, dietary treatment with the CF level of 16.7 g/kg of DM was significantly lower than the other dietary treatments (P < 0.05). The recommended range of dietary CF level for growing male CMD should therefore be between 42.6 and 77.9 g/kg of DM.

“…In fact, the AME n of the diet increased significantly with SFH inclusion at both ages. Jiménez-Moreno et al (2013a) and González-Alvarado et al (2010) in broilers reported also a 2.1% and 4.4% increase in the energy content of the diet with the inclusion of 2.5 and 3.0% OH, respectively. In this respect, Hetland et al (2003) showed that OH inclusion increased amylase activity and bile acid concentration in the jejunum of laying hens fed a cornsoybean meal diet.…”

“…Consequently, the response of the GIT of broilers and pullets to fiber inclusion and its effects on nutrient digestibility might differ between chicken lines (Slinger et al, 1964;Walugembe et al, 2014). Most of the research on the effects of the inclusion of a fiber source in the diet on GIT development and growth has been conducted with broilers (Hetland and Svihus, 2001;Jiménez-Moreno et al, 2009a;González-Alvarado et al, 2010;Mateos et al, 2012) but little information is available in pullets. Research comparing the effects of insoluble fiber on growth performance and GIT traits in modern strains of these 2 chicken lines could help to adapt the existing information on broilers to pullets.…”

The effects of including 3% sunflower hulls (SFH) in the diet on growth performance, nutrient retention (TTAR), and gastrointestinal tract (GIT) traits were studied in chicks from zero to 21 d of age. Four treatments that resulted from the combination of 2 chicken lines (female broilers vs. brown pullets) and 2 levels of SFH (zero vs. 3%) were used. The control diet contained 2,980 kcal AME n /kg, 1.25% digestible Lys, and 8.7% neutral detergent fiber. The experimental diet included 3% SFH at the expense (wt:wt) of the whole diet. Growth performance, TTAR of nutrients, and the AME n of the diet were greater (P = 0.097 to P < 0.001) in broilers than in pullets. In absolute terms, all the organs of the GIT were heavier (P < 0.001) and the small intestine and cecum were longer (P < 0.001) in broilers than in pullets. At 21 d of age, however, the relative weight (% BW) of all the organs of the GIT (P < 0.001) and the relative length (cm/kg BW) of the small intestine and cecum (P < 0.01) were greater in pullets. Gizzard pH (P < 0.001), total short chain fatty acids concentration in the cecum (P = 0.098), and villus height (P < 0.001) and crypt depth (P < 0.05) of the ileum mucosa were higher in broilers. The inclusion of SFH increased (P < 0.05) the AME n content of the diet but did not affect bird performance, moisture content of the excreta, or the concentration and profile of fatty acids in the cecum. Dietary SFH increased gizzard weight and reduced gizzard pH (P < 0.001) at both ages. In conclusion, broilers had better growth performance, nutrient retention, and ileum absorptive capacity than pullets. The inclusion of 3% SFH at the expense of the control diet did not have any negative effect on chick performance and, in fact, increased gizzard weight, reduced gizzard pH, and improved the energy content of the diet.

Nowe linie brojlerów kurzych charakteryzują się coraz większymi możliwościami wzrostu, ale jednocześnie są bardziej podatne na różnego rodzaju zaburzenia, szczególnie dotyczące układu pokarmowego. W ostatnich latach coraz większą uwagę zwraca się na naturalne produkty roślinne, które mogą być stosowane w mieszankach jako dodatki fitobiotyczne. Wśród tych dodatków na szczególną uwagę zasługują zioła, które znajdują coraz częstsze zastosowanie w mieszankach Laskowski S., Banaszkiewicz T., Milczarek A.Influence of oregano added to diets on performance, selected organs as well as morphometric traits and pH of digestive tract of broiler chickens Summary The aim of the study was to evaluate the effect of the addition of dried oregano from different regions of the world to diets on the production results, selected organs, as well as the morphometric characteristics and pH of the gastrointestinal tract of broiler chickens. The research feedstuff was dried oregano from Poland, Turkey and Egypt and diets containing these herbs. The oregano from Poland, Turkey and Egypt was added to a wheat-corn-soybean diet in an amount of 2%. The experiment was carried out on 168 broilers Ross 308, 84 males and 84 females, randomly divided into 4 groups of 42 birds each. In this experiment, four diets for the starter period (from 1 to 21 days of age) and four for the grower period (from 22 to 42 days of age) were prepared. The control group (K) were fed a wheat-corn-soybean diet without oregano, whereas chickens from the experimental groups were fed diets with oregano from Poland (OP group), Turkey (OT group) or Egypt (OE group). During the experiment, the body weight at 1, 2, and 42 days of age, feed consumption and mortality were recorded. At 42 days of age, after 14 hours of fasting, the birds were killed and from the body of 32 chickens (8 chickens from each group) the digestive tract, heart, liver, pancreas and spleen were prepared and weighed. The gastrointestinal tract was divided into sections, and their weight and length were measured. Then, in particular segments of the gastrointestinal tract, pH values were determined. The body weight of chickens determined at 21 and 42 days of age were not significantly different between the groups. Significant differences between the groups were noted in feed efficiency during the grower period. The diet containing oregano from Turkey was utilized significantly better than the control diet. Significant differences in the pH of the glandular stomach and caecum were found. Compared with pH in the control group, pH in the glandular stomachs of chickens fed diets containing dried oregano from Egypt was significantly decreased, whereas pH in the caecum of chickens from the OT group was increased. In comparison with the control group, chickens from the groups fed diets containing oregano (except the OP group) had a significantly shorter ileum and larger intestines, and chickens fed a diet with oregano from Turkey had a smaller spleen and gizzard. The results obtained show that the chemical composi...
