AbstractThe objective of this present study was to investigate the potentiality of prebiotics (mannan oligosaccharides-MOS and fructo-oligosaccharides-FOS) in replacement of antibiotic growth promoter and their relationship with physico-chemical indices, antioxidant and oxidative stability and carcass traits of broiler chickens meat. Accordingly, 240 day-old broiler chicks of uniform body weight divided in 6 treatment groups with 5 replicate each (5 × 6 = 30) having 8 birds in each replicate. Six corn based dietary treatments were formulated viz. T1 (control diet), T2 (T1 + Bacitracin methylene di-salicylate @ 0.002%), T3 (T1 + 0.1% MOS), T4 (T1 + 0.2% MOS), T5 (T1 + 0.1% FOS), and T6 (T1 + 0.2% FOS). Significant (p < 0.05) increase in cut up part yields (%) and reduction in cholesterol and fat content in T4 (0.2% MOS) group. The water holding capacity (WHC) and extract release volume (ERV) were increase (p < 0.05) in 0.1 or 0.2% MOS supplemented group. DPPH (1, 1-diphenyl-2-picrylhydrazy) was higher (p < 0.05) and lipid oxidation (free fatty acid and thio-barbituric acid reactive substances) was lower (p < 0.05) in T4 group. The standard plate count (SPC), staphylococcus and coliform counts were decreased (p < 0.05) in T3 or T4 group. Thus, it can be concluded that mannan oligosaccharides (MOS) may be incorporated at 0.2% level in diet for improved physico-chemical indices, antioxidant and oxidative stability and carcass characteristics of broiler chickens meat and it may be suitable replacer of antibiotic growth promoter.

Abstract Antibiotics have revolutionized the intensive poultry production system as a feed additive by promoting growth, production and meat quality through improving gut health and reduction of sub-clinical infections during last five decades. However, currently, the usage of antibiotics in poultry production is under severe scientific and public scrutiny, because antibiotic growth promoter (AGP) has been linked to the possible development of antibiotic-resistant pathogens, which may pose a threat to human health. After European Union ban on in feed antibiotics as growth promoter in poultry, since 2006, prebiotics offer a potential substitute to in feed antibiotics. In this effort, the objective of this present study was to investigate the potentiality of prebiotics (mannan oligosaccharides-MOS and fructo-oligosaccharides-FOS) in replacement of antibiotic growth promoter and their relationship with physio-biochemical indices, antioxidant and oxidative stability and carcass traits of broiler chickens meat. 240 day-old broiler chicks (1 d) of uniform body weight were divided into 30 replicate groups having 8 birds in each. Six corn based dietary treatments were formulated viz. T1 (control diet), T2 (T1 + Bacitracin methylene di-salicylate @ 20 mg/kg diet), T3 (T1 + 0.1% MOS), T4 (T1 + 0.2% MOS), T5 (T1 + 0.1% FOS), and T6 (T1 + 0.2% FOS). Significant (P<0.05) increase in cut up part yields (%) and reduction in cholesterol and fat content in T4 (0.2 % MOS) group. The water holding capacity (WHC) and extract release volume (ERV) were increase (P<0.05) in 0.1 or 0.2 % MOS supplemented group. DPPH (1, 1-diphenyl-2-picrylhydrazy) was higher (P<0.05) and lipid oxidation (free fatty acid and thio-barbituric acid reactive substances) was lower (P<0.05) in T4 group. The standard plate count (SPC), staphylococcus and coliform counts were decreased (P<0.05) in T3 or T4 group. Thus, it can be concluded that mannan oligosaccharides (MOS) may be incorporated at 0.2% level in diet for improved physio-biochemical indices, antioxidant and oxidative stability and carcass characteristics of broiler chickens meat and it may be suitable replacer of antibiotic growth promoter.

Storage stability of processed chicken meat bullets (CMB) packaged under different packaging conditions in supplementation with composite antimicrobial biodegradable (CAB) films impregnated with 0.5% (v/v) cinnamaldehyde, a natural antimicrobial, was evaluated. Different treatments such as aerobic (aerobic packaged product, CAB-coated product and aerobic packaging), modified atmosphere packaging (MAP; MAP 50 : 50; CO2 and N2, F-MAP; CAB-coated product and MAP) and vacuum (VAC; vacuum packaged, F-VAC; CAB-coated product and vacuum) are assessed for various physico-chemical (pH, thiobarbituric acid reactive substances number, peroxide value and free fatty acids), microbiological (standard plate count, psychrophiles, coliforms, yeast and moulds, Staphylococci sp.) and sensory quality characteristics at 7-day intervals throughout the storage period of 35 days under refrigerated (4 ± 1°C) conditions. The CMB coated with CAB films under MAP (F-MAP) conditions had significantly (P < 0.05) better value for water activity, thiobarbituric acid reactive substances number, peroxide value and free fatty acids throughout the storage in comparison to the Control (MAP). Standard plate count was significantly (P < 0.05) lower for F-MAP than all other treatments. Staphylococci sp., coliforms, Salmonellae sp., yeast and mould, and psychrophiles were completely absent in CAB-coated products throughout the storage period. All the CAB products had better (P < 0.05) sensory attributes than their respective Controls during storage. Results concluded that the CMB coated in developed CAB films have a storage life of more than 35 days under MAP conditions under refrigerated (4 ± 1°C) conditions with the acceptable physico-chemical, microbiological and sensory quality attributes.

Consumer concern for drug residues in meat and eggs as well as ban imposed on the use of antibiotics in animal feed as growth promoter call for alternative search. A 56days feeding trial was conducted to investigate the effect of ginger inclusion with and without yeast supplementation on performance, carcass characteristics, gut micro flora of broiler chickens. A total of One hundred and eighty day, one old Arbor acre broiler chicks wereallotted on weight equalization basis to 6 dietary treatments in a 3 × 2 factorial arrangements (3 levels of ginger (0%, 4% and 5%) with and without yeast (0%, 1% levels). The treatments were replicated thrice with ten birds per replicate. Feed and water were provided ad- libtum. Performance showed that birds on combination (5% ginger and 1% yeast) recorded highest weight (1527g) with better feed conversion while least weight (1202g) and least feed conversion were recorded with birds on ginger only. Highest eviscerated weight (1362.50g) and dressing percentage (72.79%) were recorded in broiler chicks on 1%Yeast + 5% Ginger while least values (1087.50g, 62.39%) were recorded with birds on yeast only. Total bacteria count increased from 1.20 x106cfu/ml (control) to 1.70 x106cfu/ml in diets supplemented 1% yeast and 5% ginger as well as Lactobacillus count increased with supplementation level Total anaerobic count decreased from1.10 x106cfu/ml in control diet to 0.68 x106cfu/ml in birds fed1% yeast and 5% ginger likewise coliform, clostridium and bacillus counts decreased with the additives (yeast and ginger) inclusion. It can be concluded that inclusion of ginger and yeast at 5% and 1% respectively in the diets improved performance and reduced pathogenic biota without detrimental effects in broiler chickens and might therefore serve as a natural substitute for synthetic growth promoters.

The objective of the present study was to evaluate the quality of refrigerated raw milk produced by 912 farmers in the Western part of Santa Catarina State, Brazil. The parameters analyzed were fat, protein, lactose, solids nonfat (SNF) content, standard plate count (SPC) and somatic cell count (SCC). A comparative analysis study with data from 2009 and 2010 was also conducted, which has shown that SCC influenced on the physico-chemical results. It was also observed that in 2010 the values for SCC were higher than in 2009, out of the limits recommended by the legislation until 2011. The SPC values were well above the maximum level accepted, indicating high contamination of milk with aerobic mesophilic microorganisms. The data collected indicated that only 4.9% of the producers sampled in 2009 and 8.1% in 2010 were in compliance with the standards enforced by a new legislation of January 2012. There was also increase on the milk fat content as SCC increased, which was not observed with other milk components. Lactose had a gradual reduction as SCC increased. On the other hand, SNF content did not correlate with SCC variance. These results demonstrate the urgent need of improvement in milk production and better technical orientation of milk producing properties to reach higher quality standards in Santa Catarina.

Mannan Oligosaccharides

The study aimed to evaluate the use of β-mannanase and mannan oligosaccharides (MOS) to replace growth promoters in broiler diets. Four hundred male Cobb broiler chicks were used, with initial weight of 45±1g, distributed in a completely randomized design with five treatments and eight repetitions of ten birds. The treatments were: basal feed; basal feed without growth promoter; basal feed without growth promoter + β-mannanase; basal feed without growth promoter + MOS; and basal feed without growth promoter + β-mannanase + MOS. The feed intake of the birds increased in response to dietary treatments compared to basal diet during the period 1-21 days of age. A higher weight gain and improved feed conversion was found at 42 days of age among birds that had received the basal diet without growth promoter + MOS. The absolute weight at slaughter, relative carcass and prime cuts except breast weights improved in response to dietary treatments compared to the basal diet at 42 days of age. No difference was observed in relative weight of the liver, while significant differences were found in the weight of heart, gizzard, and abdominal fat. It was concluded that β-mannanase and MOS can replace the growth promoters in broiler diets without compromising production and economic performance. However, the association of these products into the feed may cause negative interaction that reduces the broiler chickens' performance

Samples of skim milk and nonfat dry milk (NDM) made from it were collected, paired and tested for pyruvate concentration, [P], and Direct Microscopic count (DMC). The skim milk was tested for Standard Plate Count (SPC) and Psychrotrophic Plate Count (PPC). The geometric average DMC of skim milk was more than three times higher than that of the paired NDM samples. However, [P] of NDM was not significantly different from that of the skim milk. Although [P] of skim milk was poorly correlated with SPC and PPC, r = .31 and .26, respectively, it was relatively well correlated with DMC, r = .64. Data were widely dispersed around the regression line when [P] was ≤ 4.0 mg/L. However, [P] increased rapidly when DMCs were &gt; 106/ml. A limit of 10 mg/L of [P] in NDM reconstituted 1:9 was chosen to represent the current U.S. Department of Agriculture Standard for DMC in NDM. This limit failed to classify about 10% of the samples correctly, assuming that each geometric mean DMC was correct. However, the probability that samples meeting the DMC standard would be rejected by the pyruvate test was quite low and the probability was moderate that samples which would be acceptable by the pyruvate test would be rejected by the DMC. For the latter, 28% of the samples having DMCs of ≥ 107/ml contained &lt; 10 mg/L of pyruvate. No sample having ≥ 10 mg/L of pyruvate had a DMC of ≤ 107/ml. Pyruvate concentration in NDM did not change during storage at 5 or 32°C for 90 days.

Background: In Vietnam, animal feed mainly depends on imported raw materials, while available agro-industrial by-products are often released into the environment and only a its unsubstantial portion used as an animal feed. Therefore, efficient use of these by-products as animal feed is essential. This work aimed to evaluate the effect of dietary levels of rice distiller’s dried grain (Rice DDG) on broiler performance, meat yield and meat quality. Methods: The research was conducted at the experimental station, Vietnam National University of Agriculture, Vietnam, from May to September 2020. A total of 240 a day-old broiler chicks were randomly assigned into 4 groups with 3 replications to receive 4 diets with different levels of RDDG at 0, 5, 8 and 10% for 14 weeks. Growth, meat yield and meat quality were estimated. Result: ADG was higher in broiler chickens fed diets with rice DDG compared to that in control diet at 12 and 14 weeks (P less than 0.05) while ADFI and FCR were not affected by the diets. There were significantly no differences in meat yield and quality among the diets. In conclusion, rice DDG could be used to partially replace main ingredients in chicken diets.

Outbreaks of enterohemorrhagic Escherichia coli O157:H7 have been commonly associated with products derived from ground beef, but recently the organism has been implicated as the causative agent in outbreaks involving yogurt and cheese. This finding has raised concern about the potential for its growth and survival in fermented dairy products. A bioluminescent strain of E. coli O157:H7 was used to determine postprocessing survival in yogurt with live cultures at pH 4.17, 4.39, and 4.47 stored at 4 and 10°C. In addition, survival of E. coli O157:H7 was monitored during the manufacture of Cottage, Colby, Romano, and Feta cheeses. Results indicated survival for 8 and 5 days at 4 and 10°C respectively in yogurt at pH 4.17, 17 and 15 days at 4 and 10°C respectively in yogurt at pH 4.39, and 17days at both 4 and 10°C in yogurt at pH 4.47. E. coli O157:H7 did not survive cooking procedures at 56°C in Cottage cheese. However, the pathogen survived for 27, 30, and 27 days in Colby, Romano, and Feta cheeses respectively. A high correlation of r2 &gt; 0.89 was obtained between counts of bioluminescenct colonies and standard plate count for all yogurt and cheese varieties, indicating that bioluminescence was a sensitive and rapid indicator of cellular viability for E. coli O157:H7. Survival of the pathogen, as indicated by this method, is possible in highly acidic environments even at refrigeration temperatures. This poses a potential hazard should postprocessing contamination occur.

The 3M Company has developed a sample-ready system (Petrifilm ™ SM) for enumerating bacteria in milk and other food products. The testing unit consists of Standard Methods culture medium coated onto a base film and overlaid with a second film coated with a cold-water-soluble gelling agent and tetrazolium indicator dye. As such, the system is ready to accept samples of product. A pipette or 0.001-ml plate loop continuous pipetting syringe can be used for applying samples. In this study, both methods of sample addition were used and results compared with those of the Standard Plate Count (SPC) and standard Plate Loop (PL) methods for determining bacteria numbers in raw milk. In total, 108 samples were analyzed in duplicate by each of the four methods. The correlation coefficients (r) between the 3M-SPC and SPC, 3M-PL and PL, 3M-PL and SPC and PL and SPC were 0.946, 0.935, 0.941, and 0.974, respectively. Repeatability, as measured by mean log10 variance for duplicate determinations, was essentially the same for the four methods, and in all instances less than 0.005. The mean log10 differences between the SPC and 3M-SPC, and SPC and 3M-PL were, respectively, −0.177 and −0.168. The preceding statistical criteria suggest the Petrifilm™ SM method to be a suitable alternative to the SPC or the PL procedure.
