The study examined the effect of dietary supplements of sodium selenite (SS), selenium-enriched yeast (Sel-Plex®, SP) and selenium-enriched alga Chlorella (SCH) on growth traits, carcass analysis, selenium content in breast meat, glutathione peroxidase (GSH-Px) activity in breast and thigh meat and liver of chickens. The experiment was realized with seven hundred thirty-five cockerels Ross 308 randomly divided into 7 dietary treatments with 3 replications in each treatment. Chickens were fed a diet supplemented with 0 (control), 0.15 or 0.30 mg of selenium/kg in the form of sodium selenite (SS), Sel-Plex® (SP) and selenium-enriched alga Chlorella (SCH). Selenium addition influenced body weight at 21 (P ≤ 0.001) and 35 (P ≤ 0.05) days of age. Significantly higher body weight at 35 days of age was determined in chickens receiving 0.15 mg of selenium from SP (2 122 g) and 0.3 mg of selenium from SCH (2 116 g) contrary to dietary treatment with a lower level of selenium from SCH (2 010 g) per kg of feed. The selenium content in breast muscle was increased (P ≤ 0.001) by both the lower and higher selenium concentration in the form of SP (0.6 and 0.85 mg/kg dry matter) and SCH (0.6 and 0.82 mg/kg dry matter) in comparison with the control (0.31 mg/kg dry matter). A significant increase (P ≤ 0.001) was ascertained even in SS treatments, but no significant differences were found between both levels. The selenium source and level, including SS, significantly (P ≤ 0.001) influenced the GSH-Px activity in breast and thigh meat.

This study examined the effects of supplementation of dietary sodium selenite and sodium enriched alga <I>Chlorella</I> on growth performance, selenium concentration in breast meat and excreta, activity of glutathione peroxidase in meat, and oxidative stability of meat in broilers. Sexed broiler cockerels Ross 308 were allotted to 3 dietary treatments, each comprising 100 chickens. The basal diet was supplemented with 0 (control) or 0.3 mg/kg Se from sodium selenite (SS) or Se-<I>Chlorella</I> (SCH). Dietary supplementation with SCH increased (<I>P</I> < 0.05) body weight. The breast muscle Se concentration was increased (<I>P</I> < 0.05) by SCH (0.70 mg/kg DM; 0.36 mg/kg DM in control) supplementation, but not (<I>P</I> > 0.05) by SS (0.49 mg/kg DM) supplementation. The concentration of Se in excreta was highest in the SS group. The activity of GSH-Px in breast meat was significant <I>P</I> < 0.05) in all treatments (0.16 U/g in control, 0.30 U/g in SS and 0.23 U/g in SCH group). The inclusion of SCH in the diet enhanced the oxidative stability of meat expressed as reduced malondialdehyde (MDA) values in breast meat after 0; 3 and 5 days storage in refrigerator at 3 to 5°C.

Selenium (Se) is able to transform from inorganic to organic forms via many bacterial species. This feature is being considered for delivering more bioavailable selenium compounds such as selenocysteine and selenomethionine for human and animal diet. This study investigated the effects of bacterial selenoprotein versus inorganic Se on the carcass characteristics, breast meat selenium content, antioxidant status, and meat quality of broiler chickens. One hundred and eighty chicks were randomly allotted to five treatments of a basal diet supplemented with no Se, sodium selenite, Enterobacter cloacae Selenium (ADS1-Se), Klebsiella pneumoniae-Selenium (ADS2-Se), and Stenotrophomonas maltophilia-Selenium (ADS18-Se). The results showed that bacterial selenoprotein has the ability to deposit more Se in the breast meat compared to sodium selenite. Both Se sources reduced breast meat drip loss, cooking loss, shear force, and 2-thiobarbituric acid reactive substances (TBARS) significantly. It also increased total antioxidant (TAC) and glutathione peroxidase (GSH-Px) in comparison with the negative control. The highest activity of (GSH-Px), catalase (CAT), and superoxide dismutase (SOD) was found in bacterial selenoprotein. In conclusion, bacterial selenoprotein is more efficient than sodium selenite in increasing the breast meat Se deposition and oxidative capacity of broiler chickens. Therefore, it can be effectively used to produce Se-rich meat as a functional food.

The objective of the study was to evaluate feeding effect of microparticle protein derived from soybean meal and fish meal combined with Lactobacillus sp. at 1.2 mL on physiological condition of digestive tract and productivity of broiler. Total of 192 broiler, with initial body weight was 481.0 ± 67.2 g, given dietary treatment starting on day 21 until day 42. The experiment was assigned in a completely randomized design with 8 treatments and 4 replications. Dietary treatment were 21% intact protein (T0), 18% intact protein (T1), 21% microparticle protein (T2), 18% microparticle protein (T3), T0+Lactobacillus sp.1.2 mL (T4), T1+Lactobacillus sp.1.2 mL (T5), T2+Lactobacillus sp.1.2 mL (T6), T3+Lactobacillus sp.1.2 mL (T7). Parameters measured were total ileal lactic acid bacteria (LAB), Coliform and pH, rate of passage, daily body weight gain (DWG) and also carcass weight. Data were subjected to analysis of variance and followed by Duncan multiple range test (P<0.05). Experimental results showed that microparticle protein diet added with Lactobacillus sp. (P<0.05) increased total LAB and DWG, but decreased Coliform population, and slowed down the rate of passage. However, carcass weight was not significantly affected by treatments. Feeding microparticle protein (18%) with addition of Lactobacillus sp. (1.2 mL) can improve to be better condition of digestive tract based on higher LAB and lower Coliform populations, and increase daily body weight gain with the same carcass weight.

A total of sixty, 14-day old broiler chickens (Cobb-500) of either sex were used in this study to assess the effects of processed cassava tuber meals (0, 15, 30, and 45 gkg-1) on growth responses, meat yield, and profitability of boilers; rearing from day 14 to day 33 of ages. The experimental diets were iso-caloric and iso-nitrogenous in nature, and were supplied the broilers ad libitum throughout the trial period. Broilers fed on control diet (i.e. exclusion of CTM) achieved higher (P<0.01) body weight, while the broilers offered diets with the highest amount (45 gkg-1) of CTM had the lowest body weight. Increased (P<0.01) feed intake was observed in the treatments of 21 d and 28 days of age when broilers fed diets with the supplementation of CTM, but no significant differences was found among the dietary treatments in the feed consumption of the broilers during 33 day of age. FCR differed significantly (P<.01) throughout the trial period, broilers fed diets without supplementation of CTM had the superior FCR than the others. Mortality was unaffected by all the dietary treatment groups. Moreover, different body parts (feather, head, neck, wing, viscera) and meat yields (thigh, drumstick, breast, back, giblet, dressing) were not influenced by treatments. Live weights were unaffected by all the dietary groups with/without incorporation of cassava tuber meals (CTM) up to day 21 and day 28 of  ages. Statistically significant (P<0.01) decreased live weight was observed among the treatments in 33-day old birds DOI: http://dx.doi.org/10.3329/jesnr.v5i1.11552 J. Environ.

The influence of dietary nutrient concentration on performance and the growth of fat depots, breast meat and leg muscles was examined in five groups of male broiler chickens fed ad libitum with combinations of high (H), commercial (C) or low (L) energy and nutrient concentration in starter and finisher diets. Diets were changed from starter to finisher at 3 weeks of age giving 200 birds on each of five treatments: HH, HL, CC, LH and LL. Ten birds per treatment were slaughtered at weekly intervals from 0 to 70 days. Five of these were dissected into component lean tissues of breast muscles (white meat) and thigh+leg muscles (dark meat) and fat depots, and the other five carcasses were minced for chemical analyses. Data were analysed by fitting Gompertz functions to each component.Analysis of body weight, carcass components and feed intake revealed that at 70 days birds on LH approached similar liveweights to those on HH with lower overall food intakes, comparable feed conversion ratios but slightly greater fat depots. The HL birds had less fat but achieved specific weights over longer periods of time with greater feed intakes and poorer feed conversion ratios. Content of white and dark meat was always greater in HH birds, with differences between treatments being greater for white meat.Decisions on which conditions are most appropriate will be influenced by time taken to reach specific liveweights if whole birds are marketed, or the rate of growth of individual portions if further processing is considered, together with feed conversion efficiency and the relative costs of diets varying in energy and nutrient concentration.

The aim of this study was to evaluate the effect of a long-term peroral selenium supplementation in the form of sodium selenite and selenium lactate-protein complex by comparing selenium concentrations and glutathione peroxidase activity in blood of goats and their kids as well as comparing selenium concentrations in goat colostrums. For the study, a total of 27 clinically healthy pregnant white shorthair goats were used. They were divided to three groups, i.e., the control group (C) without any selenium supplementation, sodium selenite group (E1) and selenium lactate-protein complex group (E2). For four months, experimental goats received 0.43 mg of selenium per animal per day in diet; goats from the control group were given 0.15 mg of selenium per animal per day. At the beginning of the experiment, goats of all groups showed an average selenium concentration of 96 &mu;g/l in whole blood. On the parturition day, samples of first colostrum from goats and heparinized blood from goats and kids were taken. In the control group (C), average blood selenium concentrations of 111.4 ± 33.5 &mu;g/l were observed on the parturition day. In both experimental groups, selenium concentrations were significantly higher (<I>P</I> < 0.05). Average selenium concentration in the sodium selenite group (E1) was 177.2 ± 34.8 &mu;g/l and in the group supplemented with selenium lactate-protein complex (E2) 159.0 ± 28.5 &mu;g/l. Average glutathione peroxidase (GSH-Px) activity in blood of control goats (C) was 581.9 ± 99.2 &mu;kat/l, in group E1 1 154.6 ± 156.2 &mu;kat/l and in group E2 1 011.6 ± 153.6 &mu;kat/l. GSH-Px activity in experimental groups was significantly higher (<I>P</I> < 0.05) as compared with the control group. Average selenium concentrations in colostrum was in the control group 40.1 ± 12.8 &mu;g/l, in E1 99.0 ± 29.9 &mu;g/l and in group E2 79.0 ± 17.7 &mu;g/l. Colostral selenium concentrations in experimental groups were significantly higher (<I>P</I> < 0.05) as compared with the control group. No significant difference in the monitored parameters was found between experimental groups. In kids of control mothers (kC), average selenium concentrations in blood on the parturition day were 62.4 ± 22.9 &mu;g/l; kids of mothers supplemented with sodium selenite (kE1) showed average selenium levels of 100.0 ± 31.2 &mu;g/l, and the average selenium concentration in kids of mothers receiving lactate-protein complex was 83.4 ± 20.1 &mu;g/l (kE2). Average GSH-Px activity in control kids (kC) was 402.1 ± 153.9 &mu;kat/l. Kids from kE1 showed average activity of GSH-Px 806.1 ± 254.9 &mu;kat/l and kids from group kE2 529.9 ± 119.8 &mu;kat/l. Statistically significant difference (<I>P</I> < 0.05) was found only between kC and kE1 which showed significantly higher selenium concentration and GSH-Px activity. The results of this study confirm that both forms of selenium administered in experimental groups (i.e., sodium selenite and selenium lactate-protein complex) had similar biological effect in goats. However, results obtained in kids indicate a better effect of supplementation with sodium selenite.

&nbsp;A 2 &times; 3 factorial design experiment was conducted to evaluate the effect of adding lycopene <br />(0 and 75 mg/kg) and vitamin E (0.50 and 100 mg/kg) to the diet of chickens. Moreover, the study investigated growth traits, oxidative stability and chemical composition of leg meat and the vitamin content of meat and liver. The study was conducted using five hundred and forty Ross 308 male broilers that were assigned to one of the six dietary treatments. Significant interactions between lycopene and vitamin E additions affected the body weight of 21-days-old chickens (P = 0.005), the malondialdehyde content in fresh leg meat (P &lt; 0.001) and leg meat stored for 3 days at temperatures of 2.5 to 4&deg;C (P = 0.032), the cholesterol content in leg meat (P &lt; 0.001) and the lycopene content in liver (P = 0.006). The chickens with the highest body weight were fed 75 mg/kg of lycopene and 50 mg/kg of vitamin E. The vitamin E supplement increased the oxidative stability of fresh and stored leg muscle (P &lt; 0.001). The lowest mean cholesterol value (3.49 g/kg of dry matter) was found out in the meat from broilers that were fed 75 mg/kg of lycopene in contrast to broilers fed the control treatment without lycopene (3.93 g/kg of dry matter). Dietary vitamin E significantly reduced the fat content (P = 0.033) and increased the ash content of&nbsp;leg meat. The highest lycopene concentration in liver (2.82 mg/kg of dry matter) was in chickens that were fed the highest levels of vitamin E and lycopene in contrast with the control group (0.28 mg/kg of dry matter). &nbsp;

The goal of the experiment was to compare the effect of four different forms of selenium (Se) &minus; sodium selenite (SS), lactate-protein selenium complex (SL), selenium enriched yeast (SY), and selenium-proteinate (SP) supplemented to pregnant goats on Se concentration and glutathione peroxidase (GSH-Px) activity in the blood of goats on the day of delivery and also on Se concentration and GSH-Px activity in the blood of newborn kids. The experiment involved 33 pregnant goats of White Short-haired breed. The supplementation started 6 weeks before the parturition. The goats were divided into 5 groups: control group&nbsp;C, not supplemented, and 4 trial groups (SL, SP, SS, SY), which received Se in the above stated forms by the means of supplemented pellets (300 g per animal per day) at a rate 900 &mu;g Se/kg of dry matter. The average Se concentrations in the blood of the goats were 79.6 &mu;g/l in group C, 152.6 &mu;g/l in group SL, 167.1&nbsp;&mu;g/l in group SP, 144.9 &mu;g/l in group SS, and 152.9 &mu;g/l in group SY. Selenium concentrations in all 4 trial groups were significantly higher (P &lt; 0.01) than in control group, however no significant difference was found between individual trial groups. Likewise, the activity of GSH-Px in goat blood increased significantly in all supplemented groups compared to the controls; however we did not discover any significant differences in activity of GSH-Px between the individual selenium-supplemented groups. The Se concentrations in the blood of kids were significantly (P &lt; 0.01) higher in the selenium-supplemented groups (SL &ndash; 94.9&nbsp;&mu;g/l, <br />SP &ndash; 87.5 &mu;g/l, SS &ndash; 87.6 &mu;g/l, SY &ndash; 92.5 &mu;g/l) than in the control group (C &ndash; 49.4 &mu;g/l), but we did not discover any differences between the individual experimental groups. The activity of GSH-Px in the blood of the kids tended towards higher values in the supplemented groups than in the control group, but the values were significantly higher (P &lt; 0.05) only in groups SY and SL. We have found significant correlation between GSH-Px activity and Se concentration in the blood of goats (r = 0.86) and newborn kids (r = 0.95). Likewise, there was significant correlation between Se concentration in the blood of goats and their kids (r&nbsp;= 0.74). We discovered that the kids are reaching physiologically only about 60% of Se status in whole blood in comparison with their mothers. Our results are suggesting that all the above forms of Se were similarly utilised and transferred into the foetus in the goats. &nbsp;

An experiment was conducted to compare the effect of dietary sodium selenite and selenomethionine on selenium and α-tocopherol concentration in breast meat, oxidative stability of meat in broilers, and on growth performance, but only as an unimportant criterion in this case. Sexed broiler cockerels Ross 308 were allocated to 3 dietary treatments, each comprising 100 chickens. The basal diet was supplemented with 0 (control) or 0.3 mg/kg Se from sodium selenite (SS) or selenomethionine (SM). Dietary supplementation with SM increased (<I>P</I> < 0.05) body weight, but only by about 3%. Breast muscle Se concentration was increased (<I>P</I> < 0.05) by both Se sources, but more by SM (1.32 mg/kg dry matter; 0.47 mg/kg DM in control). The concentration of Se in excreta was 3 times higher with SS supplement than with SM supplement. Dietary Se supplementation increased (<I>P</I> < 0.05) the α-tocopherol content of breast meat from 25.9 mg/kg DM in the control to 33.2 mg/kg DM when SM supplementation was used. Furthermore, lipid peroxidation decreased compared to the control. The inclusion of SM in the diet reduced (<I>P</I> < 0.05) malondialdehyde (MDA) values in breast samples after 0, 3, and 5 days of cooler storage, whereas SS decreased (<I>P</I> < 0.05) the MDA of breast meat after 0 and 3 days of storage. The results of this experiment indicate that selenomethionine in the diet of broilers is capable of simultaneously increasing the content of selenium and vitamin E in broiler meat plus its stability in storage.

An experiment with broiler chickens was conducted to compare the relative bioavailability of liquid methionine hydroxy analogue free acid (MHA-FA) with that of DL-methionine (DLM) during fattening to 35 days of age. Ross 308 male chicks were allotted to 9 treatments, each consisting of six replicates of 140 birds/pen. Four graded levels (0.04, 0.08, 0.16, and 0.28 %) of MHA-FA or DLM products (weight/weight comparison) were added to a maize-wheat-soyabean meal basal diet deficient in sulphur amino acids. The criteria of response were body weight, feed conversion ratio, carcass yield and breast meat yield. Significant responses to graded levels of both methionine sources were observed in all response criteria. Using a multi-exponential model describing the dose-response relationships, the bioavailability estimates of MHA-FA relative to DLM on a weight-to-weight basis were 68, 70, 54 and 59 % for body weight, feed conversion, carcass yield and breast meat yield, respectively. If MHA-FA was compared with DLM on equimolar basis its bioavailability was 77.7, 79.0, 59.3 and 64.6 for body weight, feed conversion, carcass yield and breast meat yield, respectively. The bioavailability of MHA-FA for carcass yield and breast meat yield was significantly (P < 0.05) lower than that of DLM on a weight-to-weight and on equimolar basis.
