Abstract Freeze-dried beef samples were partially defatted with either petroleum ether, acetone, or ethyl ether before determination of protein efficiency ratio (PER) to study the extraction effects on the composition and protein nutritional quality of the extracted beef. Defatting a protein source, such as meat or a meat product, may often be necessary to produce a test diet that contains 10% protein and 8% fat. Amino acid, carnosine, anserine, creatine, creatinine, inosine, and proximate com- 5 positions%ere determined on the extracted samples. Resulting data were compared to the composition and PER data of the beef that had no solvent treatment. Although the chemical analysis data from the study showed some variation between the proteins and other nitrogenous components of the unextracted and the extracted beef, these variations were too small to affect the protein nutritional quality of the beef as measured by PER.

Abstract. Herawati VE, Pinandoyo, Darmanto YS, Rismaningsih N, Widarto S, Radjasa OK. 2020. The effect of fermented duckweed (Lemna minor) in feed on growth and nutritional quality of tilapia (Oreochromis niloticus). Biodiversitas 21: 3350-3358. One of the raw materials used for making tilapia fish feed is soybean meal. Soybean prices continue to rise and currently reach 4,500 rupiah/kg, so that alternative feed ingredients that are cheap and environmentally friendly need to be sought. Alternative feed ingredients that can be utilized in making feed, one of which is Lemna minor meal. Duckweed (Lemna minor) which has a high nutrient content, such as 23.47% crude protein, 3.99% crude fat, 29.92% crude fiber, 23.6% ash, and 19.02% nitrogen-free extract, will be the best candidate as an alternative feed ingredient. This study aims to find growth performance and nutritional quality of tilapia fed by different feed formulations using different amounts of fermented L. minor meal. The dosage treatments of feed with fermented L. minor meal are 0% (A), 2.5% (B), 5% (C), and 7.5% (D). Feeding of tilapia using fermented L. minor meal has a significant effect (P<0.05) on total feed consumption, feed utilization efficiency, protein efficiency ratio, and relative growth rate, and had no significant effect (P>0.05) on survival rate. The results found that the best biomass weight, total feed consumption, feed utilization efficiency, relative growth rate, protein efficiency ratio, and survival rate value was in the treatment B (usage of 2.5 % L. minor meal) which were 38.58g, 110.17g, 70.10%, 2.01%, 1.98%, and 94.44%, respectively. The best nutritional quality was in the treatment B (usage of 2.5 % L. minor meal) which was amino acid lysine, the highest value of amino acid lysine was 25.22% and the highest value of linoleic fatty acid was 4.37%.

The aim of our study was to investigate the microbial quality of meat products and on some clinical samples in Abidjan focused onStaphylococcusgenus and the toxin production profile ofStaphylococcus aureus(S. aureus) isolated. Bacteria were collected from 240 samples of three meat products sold in Abidjan and 180 samples issued from clinical infections. The strains were identified by both microbiological and MALDI-TOF-MS methods. The susceptibility to antibiotics was determined by the disc diffusion method. The production of Panton-Valentine Leukocidin, LukE/D, and epidermolysins was screened using radial gel immunodiffusion. The production of staphylococcal enterotoxins and TSST-1 was screened by a Bio-Plex Assay. We observed that 96/240 of meat samples and 32/180 of clinical samples were contaminated byStaphylococcus. Eleven species were isolated from meats and 4 from clinical samples. Forty-twoS. aureusstrains were isolated from ours samples. Variability of resistance was observed for most of the tested antibiotics but none of the strains displays a resistance to imipenem and quinolones. We observed that 89% of clinicalS. aureuswere resistant to methicillin against 58% for those issued from meat products. AllS. aureusisolates issued from meat products produce epidermolysins whereas none of the clinical strains produced these toxins. The enterotoxins were variably produced by both clinical and meat product samples.

The research was aimed to evaluate the effect of different fedding frequencies to the quality of growth is protein efficiency ratio, meat protein mass and meat calcium mass of crossbred native chicken (male native chicken x female laying hen). The material used was 120 unsexed birds with average body weight 97,49 ± 5,40 g (CV = 12,4%), were kept until 7 weeks. The experiment was designed as completely randomized design with 4 treatments and 5 replications. There were 6 birds each per experiment. Treatments applied were T1 (feeding a time a day, at 06.00 am), T2 feeding two times a day, at 06.00 am and 06.00 pm), T3 (feeding three times a day, at 06.00 am, 12.00 am and 06.00 pm), T4 (feeding four times a day, at 06.00 am, 12.00 am, 06.00 pm and 12.00 pm). Parameters measured were protein efficiency ratio, meat protein mass and meat calcium mass. Data were analyzed according to analysis of variance (ANOVA) determine the effect of treatment. Different feeding frequencies were not significant (P>0,05) on protein efficiency ratio, meat rotein mass and meat calcium mass. Conclusion of this research explain different feeding frequencies against crossbred native chicken, didn’t change the rate of protein efficiency ratio, meat protein mass and meat calcium mass.

ABSTRACT Objective In the biome of the Brazilian Cerrado, there are a lot of fruit tree species that stand out for their sensory quality and for presenting potentialities in the market of pulp and almond. Among these species, the pequi deserves attention because it has an almond rich in proteins and that is little explored. The aim of this study was to evaluate the biological quality of defatted pequi seed flour supplemented with lysine. Methods Two designs were done in this study; in the first, the animals were divided into four diet groups: control, protein-free, defatted pequi seed flour and defatted pequi seed flour supplemented with lysine. The protein-free diet was exempt of proteins and the other diets had a protein content of 10% and differed in protein source (casein: control diet or defatted pequi seed flour: test diets). The experiment lasted for 14 days. In the second design, 36 animals were used and followed-up for 28 days. The division of the experimental groups was kept, except for the protein-free diet group, which was excluded. By the end of the test, the animals were anaesthetised and euthanized. Results The results showed that the protein efficiency ratio of the control group was significantly higher than the other groups. For the other indices, the groups that received defatted pequi seed flour did not differ statistically among themselves. Conclusion These findings have shown an effect of supplementation on the protein efficiency ratio when comparing the test diets, however, when compared to the control group, no improvement was found.

The purpose of this study was to evaluate the functional properties of dried herbs (Thymus vulgaris L., Origanum vulgare L., Salvia officinalis L.) to improve the quality characteristics and microbiological stability of Hungarian meat product, pariser. The addition of herbs did not affect the microbial properties of the product. According to the Decree No. 4 of 1998 of the Ministry of Health, pariser can be considered safe. The nutritional quality of the different forms of pariser was also acceptable. However, the addition of oregano, sage and thyme changed the flavor characteristics of the parisers and the higher meat content would increase the final price of the product.

(Protein efficiency of broiler chickens fed with diets containing kayambang leaves meal)ABSTRACT The aim of the experiment was to determine the utilization of kayambang (Salvinia molesta) leaves meal until 18% based on its effects on protein consumption, protein intake, meat protein mass and protein efficiency ratio. One hundred broiler CP 707 day-old unsexed chicks, with an average body weight 502,48± 6,99 g age 15 until 42 days. This study used a completely randomized design (CRD) with 4 treatments and 5 replications and each replication consisted of 5 chickens.. The treatments diets were T0 (basal diet), T1 (6% Salvinia molesta leaves meal), T2 (12% Salvinia molesta leaves meal), and T3 (18% Salvinia molesta leaves meal). The results showed that administration of Salvinia molesta leaf meal up to 18% level in the diet resulted in a decrease in the quality of the ration so that the protein utilization also decreased as indicated by the decline in the value of protein intake, protein intake, protein mass of meat and protein efficiency ratio.
