Protein Levels

Two experiments evaluated brewer's yeast slurry [mean (� s.d.) dry matter (DM) 9.7 � 3.8% and nitrogen (N) content 45.6 � 19.5 gkg DM] as a source of dietary protein for steers on a low N hay diet (experiment 1) and as a low cost supply of protein in a feedlot diet (experiment 2). Experiment 1 was an attempt to improve the N supply to rumen microflora, and total protein to the intestine. There was no improvement in liveweight gain of steers, or in their feed conversion efficiency (FCE), when up to 4.4 kg of yeast slurry (i.e. 423 g DM) was added to the basal diet. Mean (� s.e.) liveweight gain of non-supplemented steers was 402 f 13 1 g/day, with a mean (� s.e.m.) FCE of 12.2 � 1.9 kg DM intake/kg liveweight gain. There was a significant (P<0.05) improvement in liveweight gain (714 g/day) and FCE (7.8 kg DM intake/kg liveweight gain) when cottonseed meal, included as a positive control treatment, was added to the hay diet; however, N intake was higher in this diet (97.7 g/day) than in those based on yeast slurry (range 43.6-62.3 g/day). Experiment 2 was designed to assess the suitability of yeast slurry for replacing cottonseed meal and lucerne chaff as a protein source in grain-based feedlot diets. Yeast slurry did not significantly increase liveweight gain of steers, but when 1 diet with 61% yeast slurry (percentage fed, range 0-71.4%) was excluded from the evaluation, increased dietary proportions of yeast were associated with increased liveweight gains (r = 0.99) and carcass yield (r = 0.89). The range in slurry DM contents (4.8-15.6%) required close monitoring, with daily changes made to the amounts of slurry offered to maintain dietary N and protein levels in the experiments. This range would make it difficult for commercial feed compounders to produce a diet of consistent quality.

Maximum Improvement

Ross 308 broiler chicks (n = 240) aged 1 day were assigned to five groups for eight replicates (six chicks for each) (3♂ and 3♀). Basal dietary groups were supplemented by 2000, 4000, and 6000 mg/kg cinnamon (CN) for 21 days. Basal diet alone was used as a negative control, and basal antibiotic diet (Colimox) was used as a positive control. At 10, 14, and 21 days of age, chicks that received 2000 mg CN and Colimox had a higher body weight, resulting in an increase in body weight gain. CN also resulted in the maximum improvement in the feed conversion ratio and feed efficiency over 1–21 days at the level of 2000 mg/kg. At days 10, the maximum relative breast weight was 2000 mg/kg of CN. Mean serum albumin concentrations, duodenal villus height, and goblet cell density increased (p < 0.05) by 2000 mg/kg of CN, and mean serum globulin and total protein concentrations and crypt depth increased (p < 0.05) by 6000 mg/kg of CN compared with control. Increased cecal Escherichia coli number was CN dose-dependent. In conclusion, dietary inclusion of 2000 mg/kg CN can be applied as an alternative to in-feed antibiotics for broiler starter diet.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

This study aimed to evaluate the administration of Lactobacillus plantarum AKK-30 and Saccharomyces cerevisiae B-18 as probiotics in reducing cholesterol of blood, egg, and meat and also the production performance of laying quail (Coturnix coturnix Japonica). A number of 600 birds of the twenty one-day-old quails were distributed in a completely randomized design with 5 treatments and 6 replications (initial BW= 101.35 ± 1.64 g). Treatments were as follows: A = negative control (basal diet without probiotic), B = 1% of L. plantarum AKK-30 (107 cfu/g), C = 1% of S. cerevisiae B-18 (106 cfu/g), D = 1% of a probiotic consortium, E = positive control (commercial probiotic). Parameters observed were blood biochemistry profiles, product quality, and production performance. The results revealed that administration of 1% S. cerevisiae (C) resulted the lowest cholesterol in blood (101.75 mg/dL) and egg (9.44 mg/g) and while administration of 1% L. plantarum(B) increased meat protein and decreased fat content (P<0.05). Level of blood triglycerides, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were not different among treatments. Probiotic treatments did not affect the growth performance, quail day production (QDP), feed conversion ratio (FCR) and egg uniformity. However, probiotic increased diameter of egg yolk (P<0.05). It was concluded that administration of single probiotic L. plantarum AKK-30 or S. cerevisiae B-18 improves the quality of laying quail products.

AbstractAnastrepha fraterculus (Wiedemann), a pest of great economic importance in South America, needs urgently to be controlled by environmentally friendly methods such as the sterile insect technique for which mass rearing of insects is required. Because oogenesis takes place during the adult stage, mass-rearing facilities should provide the females a diet that maximizes egg production at the lowest cost. Accordingly, we investigated the effect of artificial protein sources in the adult diet (yeast derivatives of different cost but with similar amino acids profiles, and the addition of wheat germ) on fecundity. Additionally, we evaluated different ratios of yeast derivatives or wheat germ on ovary maturation, fecundity, and fertility as well as their association with the nutrient content of females. Females fed hydrolyzed yeast and yeast extract attained the highest fecundity level, and those fed brewer's yeast the lowest. Reducing the amount of hydrolyzed yeast, an expensive protein source, in the diet negatively affected fecundity and ovary maturation. Increasing the amount of brewer's yeast, a low-cost protein source, did not favor fecundity. The addition of wheat germ in the adult diet improved fecundity regardless of the yeast derivate considered. Percentage of egg hatch was not affected by the diet. Nutrient content of A. fraterculus females varied according to the adult diet provided and mating status. Our findings provide novel baseline information to understand the role of nutrition on reproductive performance of A. fraterculus females and are discussed in the context of resource allocation. They also provide valuable advances in the search for cost-effective adult diets at fruit fly mass rearing facilities.

The objective of this study was to evaluate the replacement of soybean meal by extruded whole soybean in the feeding of pigs in the nursery phase. Thirty-six piglets (Landrace x Large White), with 45 days weighing on average 11.36 kg, distributed in arandomized block design, three treatments, six replicates, two animals per repetition were used. The treatments consisted of: control treatment (T1) basal diet, basal diet with 10% replacement of soybean meal by extruded soybean (T2), basal diet with 20% replacement of soybean meal by extruded soybean (T3). The variables analyzed were: average weight, feed intake, weight gain and feed conversion. The levels of ureatic activity, ether extract, crude protein, protein solubility and volatile moisture of extruded soybean were verified. No difference was found (P>0.05) between the inclusion levels of extruded soybean in piglet diets in the nursery phase for the variables studied. The processing of extruded whole soybean did not affect its digestibility. Extrudedsoybeans at a level of up to 20% included in piglet feeding during the nursery phase can be a possible substitute for soybean meal, without compromising the performance of the animals.

A total of 600 day-old broiler chicks (Ross 308) confirmed for the absence of Salmonella were randomly allocated to five treatments each with 10 replicates: negative control (basal diet only); positive control (basal diet) + infected with Salmonella; T1, Salmonella infected + avilamycin; T2, Salmonella infected + Bacillus subtilis (ATCC PTA-6737; 2 × 107 CFU/g) and T3, Salmonella infected + B. subtilis (DSM 172999; 1.2 × 106 CFU/g). The results revealed that feed intake (FI) and body weight (BW) were significantly (p < 0.01) lower in T1 compared to T2. The feed conversion ratio (FCR) was significantly (p < 0.01) lower in T2 and T3 compared to other treatments. Similarly, the performance efficiency factor (PEF) was also significantly (p < 0.01) higher in T2 and T3 compared to positive control. Villus height was significantly (p < 0.01) higher in T2 compared to all other treatments. However, villus width and surface area were significantly (p < 0.01) higher in T1. In conclusion, dietary supplementation with B. subtilis improved growth and intestinal health by reversing the negative effects of Salmonellosis.

Water-soluble low molecular weight β-glucan (WSLMG) was successfully prepared via γ-irradiation of insoluble β-glucan extracted from brewer’s yeast cell walls. The WSLMG content in an irradiated sample increased as the irradiation dose increased. The WSLMGs with a molecular weight (Mw) of 49, 25, and 11 kDa, obtained at correlative doses of 100, 200, and 300 kGy, respectively, were tested using growth promotion and immune stimulant effects in broilers. Supplementation with 500 ppm WSLMGs not only increased the survival rate (33.3%) and average body weight (40%) but also reduced the feed conversion rate (35.4%) in tested broilers. In addition, WSLMGs enhanced both nonspecific and specific immune components in the blood of supplemented broilers. The WSLMG with Mw ~25 kDa showed the highest effect on the growth performance and immunomodulatory capability in the immune systems of the tested broilers. In conclusion, this product demonstrates substantial promise as an immunostimulant and growth-promoting additive for poultry.

The insoluble β-glucan extracted from the cell wall of brewer’s yeast was dispersed in deionized water for swelling, then irradiated in order to degrade into water-soluble β-glucan. The results revealed that the water-soluble β-glucan contents in the irradiated samples were increased with radiation dose to 25.89, 49.07 and 66.71%; whereas their molecular weight (Mw) decreased to 48.1, 23.0 and 10.8 kDa by gamma irradiation at 100, 200 and 300 kGy, respectively. The supplementation of poultry feed with the radiation degraded β-glucan enhanced both non-specific (total white blood cells, lymphocytes, neutrocytes) and specific immune components (anti-Newcastle disease, anti-Gumboro disease virus and anti-infectious bronchitis virus antibodies) in the broilers. In comparison with the control, broiler fed normal poultry foodstuff without β-glucan, the supplementation of radiation degraded β-glucan not only increased the survival rate of the testing broiler about 33.3% and their average body weight of about 24.4%, but also reduced the feed conversion rate from 4.8 to 3.1 kg. The β-glucan oligosaccharides that having Mw of about 25 kDa produced by gamma irradiation at 200 kGy showed the highest effect on the growth performance and immunomodulatory capability in the immune system of the testing broilers. This product is promising to be applied for production of the safe stimulator of immunity for broiler chickens.

This study was carried to evaluate the “Effect of Garlic (Allium sativum) oil inclusion on carcass quality, growth performance and cost implication of broiler chickens”. A total of 180 day–old-(Arboacre) broiler chicks purchased from a reputable hatchery was used in the study which lasted for eight (8) weeks. The birds were divided into four experimental groups; each group was further subdivided into three replicates of fifteen birds per each in a Complete Randomized Design (CRD). The birds were fed on two basal diets (Starter and finisher) in an experiment which lasted for eight weeks. The garlic oil (Allum sativum) was added to the basal diet at (0.00, 0.1, 0.2, 0.3%) level respectively. The treatment were T1, T2, T3, and T4 with T1 serving as control. Growth performance, carcass characteristics, and cost implication were recorded. At the end of the experiment, the birds were slaughtered, dressed to estimate the different parameters. The result showed that the diet with 0.3% garlic oil inclusion had significantly (P<0.5) highest body weight and highest dressing percentage. Control treatment (0.0%) had highest feed intake and best feed conversion ratio. The mortality rate was not affected significantly by the addition of garlic oil in broiler diet. The garlic oil inclusion reduced the mortality rate of the birds, increases productivity and food safety. The result showed on cost implication reveal the economical evaluation of the experiment diets indicated that, the diet with 0.3% level of garlic oil showed the highest profitability ratio as compared to the group. This might be due to the highest return of the weight gains recorded by this group of chicken.

Abstract This study was intended to assess the effect of graded replacements of corn gluten meal with Brewer’s yeast (Saccharomyces cerevisiae), with and without Bacillus megaterium supplementation, on performance, carcass characteristics, and the gut broilers microflora composition. A total of 720 mixed sex one-day-old broiler chicks (Ross 308) were randomly assigned to six dietary treatment groups (6 replicates each) in a 3 × 2 factorial arrangement, including 3 levels of Brewer’s yeast (BY; 0, 25, and 50%, to replace corn gluten meal; CGM) in the presence (+) or absence (−) of B. megaterium used as probiotic (Pro). The results showed that broilers fed diets containing BY up to 25% had comparable body weight (BWG), feed intake (FI), and feed conversion ratio (FCR) to the birds fed only CGM, over the entire feeding period (days 1–35). Conversely, higher levels of BY (50% replacing CGM) registered the lowest BWG values (P < 0.001) and impaired FCR (P < 0.010), but without effects on FI. The BY diets did not significantly affect the main broiler’s carcass traits. The diets with Pro did not involve modifications on carcass and organs size, but a tendency to increase the gizzard weight (P = 0.094) and to decrease SIL (P = 0.076) was observed. Pro addition also, reduced the cecal pH (P = 0.040) and diminish the total coliforms (P < 0.010), Clostridium spp. (P < 0.0001), and E. coli (P < 0.0001) count, whereas LAB, Bacillus spp., and Enterococcus spp. bacteria were increased (P = 0.022; P < 0.0001, and P < 0.0001, respectively).
