Alga Scenedesmus Quadricauda

The selenium-enriched Scenedesmus biomass of patented selenium-resistant strain SeIV was tested in a broiler chicken diet in comparison with sodium selenite supplementation. Feed conversion, mortality and live weight were not significantly influenced by the source of selenium. Supplementation of either form of selenium significantly increased the Se concentration in breast muscle with a more pronounced effect (P < 0.001) caused by selenium enriched Scenedesmus (635 μg/kg DM, 229 μg/kg DM in control). Breast meat of chickens fed a diet with sodium selenite or Se-Scenedesmus had a significantly (P < 0.001) higher value of glutathione peroxidase activity (0.329 μmol/g, 0.361 μmol/g) compared to the basal diet (0.190 μmol/g). The inclusion of Se-Scenedesmus biomass in the diet enhanced (P = 0.021) oxidative stability of meat expressed as reduced malondialdehyde in breast meat after 10-day cooler storage. Se-enriched Scenedesmus can be a good source of organic selenium for the production of Se-enriched chicken meat for further use in human diets. Furthermore, the Se-resistant strain SeIV was found advantageous for its fast and easy production of Se-enriched biomass.

THE EFFECT OF PARTLY SUBSTITUTION OF DIET WITH WHITE CHINESE CABBAGE (Brasscia pekinensia L) WASTE PRODUCT ON BIOLOGICAL PERFORMANCE OF BROILER CHICKEN The present study was conducted to characterize the effect of white Chinese cabbage (Brasscia pekinensia L) waste product as an alternative feed source for broiler chicken.  The experiment was conducted at Faculty of Animal Husbandry’s experimetal station for 21 days using 60 MB-202 broiler chicken. The experiment was started at 21 days of age and terminated at 42 days of age. Birds were allocated to 20 experimental battery cage, 3 birds in each cage. Completely Randomized Design (CRD) with 5 treatments and 4 replications was employed to analyze experimental data. Treatment diets were formulated as follow: R0 = 100% basal diet and 0% white Chinese cabbage waste product; R1 = 95% basal diet and 5% white Chinese cabbage waste product; R2 = 90% basal diet and 10% white Chinese cabbage waste product; R3 = 85% basal diet and 15% white Chinese cabbage waste product; and R4 = 80% basal diet and 20% white Chinese cabbage waste product. Parameters measured were: 1) daily feed consumption; 2) daily gain; and 3) feed conversion ratio (FCR). The results of the study during which feed consumption (138,09-141,57g), weight gain (64,95-68,53g), and feed conversion (2,07-2,12). The results showed that partly substitution (up to 20%) of basal diet with white Chinese cabbage waste product gave non significant (P > 0.05) effect on feed consumption, daily gain, and feed conversion ratio (FCR) of broiler chicken. It can be concluded that white Chinese cabbage waste product can be used up to 20% feed gives good results on broiler performance.

Birds fed with vegetable diets rely on the endogenous synthesis of creatine, which requires amino acids, some of which, for example arginine (Arg), are considered essential for several physiological and metabolic functions. Creatine is limited to high energy expenditure cells, particularly muscle cells. The objective of this study was to evaluate the inclusion of guanidinoacetic acid and arginine (as precursors of creatine) in vegetable diets, on the performance, quality, and yield of broiler chickens. The treatments consisted of diets based on corn and soybean meal (T1); corn, soybean meal + 3% meat meal (T2); corn, soybean meal + 0.08% guanidinoacetic acid (T3); and corn, soybean meal + 0.08% L-arginine (T4). The productive performance of the birds aged 7-, 21-, and 42-days-old was determined. Eighteen 7-day-old birds were sacrificed per treatment to evaluate breast and leg yield, and breast muscle fibers, and eighteen 42-day-old birds were sampled per treatment to determine serum uric acid, urea, creatine, lactate, and glucose concentrations. The same birds were slaughtered to calculate carcass yield in relation to live weight and commercial cut yield. The right pectoralis major muscle of each bird was used to test pH, color (luminosity L*, red index a*, and yellow index b*), and loss of water by pressure analysis, and the left side was used to analyze losses by defrosting and cooking. The data were analyzed using the software SAS. Diets to which meat or vegetable meal plus guanidinoacetic acid or L-Arginine were added resulted in higher live weight and breast meat percentage at 7 days old. Feed conversion was affected for a total period of 1 to 42 days of age (P < 0.0002). The birds with a diet supplemented with vegetable and meat meal had better feed conversion when compared to the birds that were fed with other diets. Treatments did not affect carcass and commercial cut yields, percent loss by cooking, pressure and defrosting of the broiler breast meat, or color (L, a*, and b*) and pH values.

A trial was conducted with 175 day old Ross broiler chicks to evaluate the effectiveness of Alisma canaliculatum (Water plantain or Theksa), Laminaria japonica (Sea tangle or Dashima) and Cornus officinalis (Cornelain cherry or Sansuyu) medicinal plants treated with probiotics in replacing antibiotic. Three medicinal plants were prepared in dry and flour form with treatment of probiotics. The groups were control (basal diet), antibiotic (basal diet + 0.05% OTC, oxytetracycline), Water plantain treated with Probiotics (WPP) 0.5%, Sea tangle treated with Probiotics (STP) 0.5% and Cornelian cherry treated with Probiotics (CCP) 0.5% in basal diet. The broilers were distributed in a completely randomized design having 5 replications with 7 chicks per replication in wire cage. The data were analyzed by SAS package program. Addition of three medicinal plants in broiler diets didn’t show negative effect on growth and feed conversion efficiency in broilers. Significantly highest protein percentage in broiler meat was found in groups fed the three medicinal plants treated with probiotics (WPP, STP and CCP) compared with other groups (P<0.05). Crude ash also increased significantly by the three medicinal plants addition compared to control especially in breast meat (P<0.05). Addition of probiotics treated with medicinal plants had similar beneficial effects on most of the observed parameters to those found in antibiotic-fed groups, so it implies that these three medicinal plants can be the possible alternatives to antibiotic for broiler production.Asian J.

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.

Two hundred-forty 3-weeks-old Aseel birds from Lakha, Mushki, Peshaweri and Mianwali varieties of indigenous Aseel were chosen (60 birds/variety, 30 males and 30 females) to evaluate the influence of selenium supplements on growth performance. The birds of either sex were divided according to randomized complete block design into A, B and C treatment groups (10 birds/treatment); A and B were experimental, while C was control. Se-enriched yeast (organic selenium) and sodium selenite (inorganic selenium) were supplemented @ 0.3 mg/kg in the basal diets of group A and B, respectively, while, group C was fed without additional selenium. Birds were maintained individually in battery cages from 4-21 weeks. Statistically, the results showed the reduced (P>0.05) feed intake, while enhanced (P£0.05) nutrient utilization for dry matter, crude protein, crude fiber, crude fat and ash; superior feed conversion ratio; higher live final body weight; lower (P£0.05) mortality and rearing cost in Se-enriched yeast fed birds, chiefly in the males of Lakha variety than those received sodium selenite supplemented or control diet. The study concluded that the organic selenium supplement (Se-enriched yeast) had a major influence in improving the overall growth performance of Aseel.

Thirty six individually-fed pigs were used in a within-litter comparison of the 6 treatments of a 3 × 2 factorial experiment. The pigs were about 9 weeks old at the start and were slaughtered as their individual weights reached about 200 lb.Three types of basal diet were given with and without a supplement of CuSO4.5H2O included at 0·1% (250 p.p.m. added Cu).The diets were based on (1) barley and fish meal, with 17% crude protein for pigs up to 103 lb. live-weight and 15·4 % from then on, (2) maize and soya (extracted soya bean meal), with about the same levels of protein and (3) maize and soya, but with only 13·4% crude protein for pigs up to 103 lb. and 11·9% for pigs of 103 lb. to 200 lb. Daily feed allowances were determined from a fixed scale based on live-weight.Pigs given the high-protein maize-soya diets grew more rapidly, required less feed per lb. gain and had fatter carcasses than those given the barley-fish meal diets. This was probably because of the higher TDN content of the maize-soya mixture.Pigs given the low-protein maize-soya diets grew less rapidly, required more feed per lb. gain and had fatter carcasses with smaller ‘eye’ muscles than those receiving the high-protein maize-soya diets, these being the usual effects of an inadequate supply of total protein or of an essential amino acid.CuSO4.5H2O4 added as 0·1% of each of the three types of diet improved growth rate before 103 lb. live-weight but had no consistent effect on feed conversion efficiency. Between 103 lb. and slaughter the copper sulphate did not affect performance on the barley-fish meal or high-protein maize-soya diet, but in the low-protein maize-soya diet it reduced feed conversion efficiency and rate of gain by 5%. Although this interaction was not statistically significant it agrees with an observation made in Florida and warrants further investigation.

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.

The objective of this study was to evaluate the effects of using the Saccharomyces cerevisiae yeast cell wall (YCW) as an aflatoxin B<sub>1 </sub>(AFB<sub>1</sub>) adsorbent in broiler chicken feed on performance and carcass characteristics. The present study used a randomized complete block with four treatments in a 2 (with or without AFB<sub>1</sub>) × 2 (with or without YCW) factorial design. No interaction effect (P &gt; 0.05) between AFB<sub>1</sub> and YCW was found on the studied performance variables. The addition of YCW to the diets stimulated the feed intake of chickens during 1–21 days of age. However, YCW did not significantly increase (P &gt; 0.05) weight gain nor did it change feed conversion. The presence of AFB<sub>1</sub> in the diet did not affect (P &gt; 0.05) performance parameters. The addition of YCW to the feed containing AFB<sub>1</sub> significantly increased (P &lt; 0.05) the post-fasting live weight (781.12 g), chilled carcass weight (554.41 g), and leg weight (163.34 g) compared to feed without AFB<sub>1</sub> and YCW (764.84 g; 533.41 g; 161.88 g), feed with only YCW (764.22 g; 546.87 g; 159.34 g), and feed with only AFB<sub>1</sub> (735.41 g; 510.56 g; 152.75 g). In conclusion, YCW effectively reduced some of the deleterious effects of AFB<sub>1</sub> in broilers.

A 112-day study was conducted to determine the effect of dietary organic (Copper proteinate) and inorganic (Copper sulphate) Cu source on growth performance, plasma lipids and copper residue in organs and tissues of cockerel chickens. 240 day-old commercial Black-Harco cockerel chicks were randomly distributed to 6 dietary treatments of 40 birds each. Each treatment group was randomly allocated to 4 replicates of 10 birds each. The diets were formulated to contain a basal diet (containing 30.62 and 29.71 mg/kg Cu for starter and finisher phases respectively) supplemented with organic Cu (Cu proteinate; Cu-P) or inorganic Cu (Cu sulphate; CuSO ) fed at 3 dietary levels (50, 100 and 4 150 mg/kg). The birds were fed chicks mash and grower mash at 1-56 days and 57-112 days respectively in a deep litter pen at floor space of 0.06 m2/bird. Cu-P supplementation resulted in significantly higher (P<0.05) final live weight (FLW) and total weight gain (TWG) compared to CuSO at starter phase. Better feed conversion ratio was noticed in birds fed 4 Cu-P supplemented diets compared to CuSO at 150mg/kg Cu concentration at both starter 4 and finisher phases. Birds fed 150 mg/kg Cu recorded the highest (P<0.05) feed intake value at starter phase. There was significantly higher (P<0.05) accumulation of Cu in the blood, heart, lung, liver and thigh of birds fed Cu-P than those fed CuSO . The liver Cu 4 concentration increased as dietary Cu concentration increased. Cu-P supplementation resulted in significant reduction (P<0.05) in plasma cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL) and triglyceride in comparison to CuSO . The blood 4 cholesterol, LDL and triglyceride decreased with increased copper concentration. Organic form of copper promotes growth, more bioavailable and more effective in reducing cholesterol than copper sulphate.

Context Selenium (Se) is an essential trace element and plays pivotal roles in poultry nutrition. Aims The present study was designed to compare the impact of dietary supplementation of different sources of Se on growth performance, Se concentration of breast meat, and immune response of broiler chickens. Methods In total, 300 1-day-old as hatched broilers were randomly allocated to six dietary treatments, with five replicates of 10 birds per each. The experimental diets were as follows: (1) corn–soybean meal-based diet supplemented with 0.30 mg/kg of sodium selenite, (2) basal diet supplemented with 0.30 mg/kg of Se-enriched yeast, and (3–6) basal diet supplemented with 0.15, 0.30, 0.90 and 1.50 mg/kg of nano-Se respectively. Humoral immunity was assessed by antibody titer against a 5% sheep red blood-cell suspension and cellular immunity was measured by administration of phytohaemagglutinin-p at 38 days. Key results Results indicated that during the periods from 1 to 10 days, from 11 to 24 days, from 25 to 42 days and from 1 to 42 days, average daily gain, average daily feed intake, and feed conversion ratio did not differ among the treatments (P &gt; 0.05). Assessment of orthogonal contrasts at the whole phase of feeding showed that the average daily gain in the broilers fed organic Se was significantly (P &lt; 0.05) higher than that in those fed inorganic Se, as well as nano-Se in comparison to organic Se; such effects were not observed in earlier feeding stages. Se supplementation significantly increased the Se concentration of breast muscle (P &lt; 0.0001). The birds that received 1.50 mg/kg of diet nano-Se showed higher (P &lt; 0.05) total immunoglobulin and IgG titers in primary and secondary immune responses against sheep erythrocytes respectively. Toe web swelling after 24 h and 48 h of receiving phytohaemagglutinin-p was not affected by Se supplementation (P &gt; 0.05). Conclusions In conclusion, the addition of nano-Se gave better results than did inorganic (sodium selenite) and organic (yeast selenium) forms of Se in performance traits, breast meat Se concentration and antibody response of broilers. Implications Novel elemental nanometer particulates, including nano-Se, exhibit new characteristics and a different mode of actions in comparison with organic and inorganic forms of Se sources in poultry diets. Inclusion of the nano form of Se in broiler diets and study of productive performance, immunity responses and meat quality leads to improve balanced broiler diets formulation in view of Se.
