The aimed of the study was to evaluate the caloric value as a function of the proximal composition and correlate the selling price with the nutritional values ​​of commercial cuts of tambaqui (Colossoma macropomum) and pirarucu (Arapaima gigas) in different weight classes. The sample collections were performed in two processing units located in the state of Rondônia, Brazil. Were 200 tambaquis in five weight classes were studied. And, were 77 pirarucus were studied in seven weight classes. The design was completely randomized, with processing carried out in triplicate. The Kruskal-Wallis test (α=0.05) was used to compare the averages and the Spearman correlation (ρ) between price and nutrients. The commercial cuts with the highest caloric value were the tambaqui filet (145.70 kcal/100g) and the pirarucu filet mignon (119.11 kcal/100g) (p<0.05). And the less caloric commercial cuts were steak of tambaqui (100.47 kcal/100g) and pirarucu loin 102.01 kcal/100g) (p<0.05). It was also observed that the variables caloric value and protein content did not correlate with the price of the kilo of fish for the different commercial cuts, which leads to infer that, possibly, the sensorial, market and cultural factors were responsible for the price variations. Regarding the caloric value according to the composition of the tambaqui, the Class 4 was the most efficient category for production and commercialization. And in the composition of the pirarucu, the Class 4 presented satisfactory values of proteins and lipids and a good percentage of mineral matter.

It is important to know the nutritional composition of the fish, especially the nutritional value of the commercial cuts most consumed by the population. The aimed of this study was to evaluate the chemical composition of commercial tambaqui (Colossoma macropomum) cuts in different classes of body weight. The sample collections were carried out in processing units in two municipalities in the state of Rondônia, Brazil.  The Data on 200 fish were recorded, with weight ranging from 1000 to 4700 g. Five classes of body weight were established, class 1 - below 1.2 kg; class 2 - from 1.21 to 1.8 kg; class 3 - from 1.81 to 2.4 kg; class 4 - from 2.41 to 3.5 kg; class 5 - over 3.5kg. The commercial cuts were lyophilized and intended for chemical analysis. The Kruskal-Wallis test (α=0.05) was used to compare the averages. The composition of commercial cuts was different in weight classes (p<0.05). The filet presented more representative values in mineral matter, crude protein and total lipids and lower humidity for class 4 (from 2.41 to 3.5 kg). The classes 1 and 5 (below 1.2 and over 3.5 kg) were different (p<0.05) in relation to the lipid and moisture content in the commercial filet and rib cuts. The tambaqui steak in class 4 have a higher lipid content compared to the average of the lightest body weight classes, 9.99 vs 4.50%, in addition to having a lower moisture content (p<0.05). The tambaqui band was different (p<0.05) in relation to nutritional components between body weight classes, with class 4 being richer in minerals, crude protein and lipids in dry matter. Therefore, the class 4 was the most efficient (p<0.05) for production and commercialization. Because the tambaquis with body weight between 2.4 to 3.5 kg stood out in relation to the nutritional components in the different commercial cuts.

Chemical composition of Moringa oleifera seeds obtained from the middle belt of Nigeria, Benue State, was determined and the seed was blended to form a seed meal. The Moringa oleifera Seed Meal, MOSM was included in diets at graded levels of 2.50, 5.00 and 7.50% and the dietary performance of the broiler chicks on the test diets was compared with that of a corn-soy reference diet. Results on the chemical/nutritional composition of MOSM showed that the full-fat seeds contained (%) on proximate basis, reasonable concentration of 90.38 dry matter, 25.37 crude protein, 14.16 crude fat, 4.03 mineral matter, 30.64 crude fiber, 25.80 soluble carbohydrate and 5.79 kcal/g gross energy. Analyses also gave appreciable quantities of the water and fat soluble vitamins, macro - and micro-minerals. Feeding chicks with the seed meal at graded levels in diets resulted in decrease in feed intake and body weight gain as the inclusion level increased in diets relative to the conventional diet (p < 0.05). Reduction in feed consumption could be attributed to the full-fat nature of the seed meal used which might have imparted extra-caloric effect in the test diets and slowed digestion and absorption as the analyzed nutrients content of diets. A higher ether extract value on Moringa based diets relative to the control diet was obtained. Phytochemical composition of Moringa namely phenols including tannins, saponins, phytate, cyanogenic glucoside, glucosinolates and other numerous chemical constituents affected the body weight of the chicks negatively with increasing dietary MOSM. Decrease in weight gain following increase in dietary seed meal could also be due to decrease in feed intake as a result of the bitter taste of alkaloids, saponins, acting in concert with the other Moringa phytotoxins in test diets. Survival rate (100%) was not affected indicating that the level of highest inclusion in this study (7.50%) was not fatal to the experimental animal models. Further research is progressing to ascertain the highest inclusion level possible to elicit fatality and attempts to detoxify or treat the seed meal before feeding to animals.

I prepared a “model farm” producing fattening pigs in order to examine the main risk of production and market factors affecting the profitability of fattening pig production. Values of body weight (at the beginning of fattening and at the end of fattening), mortality rate, feed conversion ratio (FCR) of fattening pig as well as the main cost and price data were recorded as the input data of the model. Production value per unit, production cost per unit and income per unit were used as output. The Monte-Carlo simulation was used in the model for risk assessment. Based on the results of the analysis, it was concluded that the production value per unit was most affected by the selling price of fattening pig (ß=0.972), the production cost per unit were most influenced by the body weight at the beginning of fattening (ß=0.567) and the feed conversion ratio (ß=0.537), in addition, the change of the income per unit was most determined by the previously factors.

The objective of the study was to develop a process for the production of a protein concentrate based on maggots (MC) of domestic fly larvae that can be used in the diet of non- ruminants’ animals as pigs and poultry. Maggots were first produced from 3 substrates called S1, S2 and S3. They were then harvested and separated from the substrates using a mesh screen box. Live maggots then incorporated at a rate of 79.15% by weight in a preconcentrate (20.85%) composed by 64.80% of cotton cake and 35.20% of wheat bran. The resulting MC was then heated in a pan for 5-10 minutes to neutralize the maggots and dried for 24 hours. The results show that the productivity of the S3 substrate (4.91g of maggots / 100g of substrate) was significantly lower than the substrates S1 (6.60g / 100g) and S2 (5.35g / 100g) (p <0.05). The DM content of the MC was 92.56%. Its nutritional values were 37.69% CP, 5.12% FAT and 11.04% CB. The estimated value in digestible energy was 2238 kcal / kg DM. The production cost of 01kgDM of MC of 160FCFA was lower than 240FCFA of the selling price of fishmeal and soya cake (400FCFA) in the local market. MC is an alternative to make low cost protein sources more available. Further studies would evaluate the essential amino acid content of the concentrate and the effectiveness of diets incorporating it into poultry and pigs’ production.

Abstract Background A growing body of evidences suggest critical role of the chicken gut microbiota in growth performance and fat metabolism. However, the underlying mechanism by which the gut microbiota affects chicken growth performance by regulating fat metabolism remains unclear. The purpose of current study was to compare cecal microbial communities between high and low body weight chickens and verify the correlation between fat metabolism and gut microbiota. Results Seven-week-old male and female chickens with significantly different body weight were used in the present study. 16S rRNA gene sequencing was used to reveal the cecal microbial community. Fat metabolism levels were compared between high and low body weight chickens. Spearman correlation analysis was used to analyze the relationship between the cecal microbiota and fat metabolism. Transferring fecal microbiota from adult chickens with high body weight into one-day-old chickens was examined by oral administration to verify gut microbiota effects on chicken growth through regulation of fat metabolism. There were significant differences in body weight, chest and leg muscle indexes as well as in cross-sectional area of muscle cells, suggesting different growth performance between high and low body weight chickens. By comparing the relative abundance of gut microbes in the cecal content in high and low body weight chickens, we found that Microbacterium and Sphingomonas were more abundant in high body weight chickens and Slackia was more abundant in low body weight chickens. The fat metabolism level was markedly different in serum, liver, abdominal adipose, chest and leg muscles between high and low body weight chickens. Spearman correlation analysis showed a positive correlation between fat metabolism and the relative abundance of Microbacterium and Sphingomonas and a negative correlation between fat metabolism and the abundance of Slackia. Hence, transferring fecal microbiota, instead of saline, from adult chickens with high body weight into one-day-old chickens improved growth performance and fat metabolism in liver. Conclusions These results suggested that cecal microbiota could affect chicken growth performance by regulating fat metabolism.

The water temperature of the tanks of the breeding herds exerts a strong influence on the process of artificial reproduction. Its monitoring through the hour-degree, serves to assist in the moment to be made the extrusion of the oocytes. The objective was to monitor the time-degree that Colossoma macropomum females need after the second dose of the hormonal induction protocol, until the time of extrusion of their oocytes. The analysis was carried out at the Fish Fishery in the municipality of Sorriso-MT. Nine breeding women were submitted to the protocol of hormonal induction with pituitary extract of carp being administered in two doses. In the former, the dose of 0.5 mg / kg was used and the second dose was 5 mg / kg body weight, with an interval of 12 hours. From the second dose, the temperature in degrees centigrade of the water from the tanks was monitored hourly until the time of oocyte extrusion. Breeders had muscle tremors, swimming in circles, and were more agitated nine hours after the second dose. The oocytes had a yellowish-brown appearance, and some had individual features. The sum of the temperature of the water in hours-degree obtained was of 243. The temperature of the water did not present variation, maintaining itself at 27 ° C. It is concluded that an hour-degree is necessary for an extrusion of oocytes in some of the things you can find in Colossoma Macropomum of 243, agreeing with the limits proposed in the literature.
