Abstract This study aimed to investigate the effect of fermented rice bran used as a feed ingredient on the apparent digestibility coefficient (ADC) of tilapia feed. The fermentation process was conducted under aerobic conditions using 2% Aspergillus niger for 24 hours. Moreover, three different types of feed were prepared with 3 replicates and these include treatment A (reference feed), B (unfermented rice bran feed), and C (fermented rice bran feed). These treatments were provided for the tilapia for 30 days. Meanwhile, the tilapia used had an average weight of 5 g/fish and reared using a recirculation system with a density of 16 fish/aquarium. The results showed that the value of ADCenergy (78.11%) in treatment C was significantly highest (P<0.05) compared to other treatments, while the lowest was in treatment B with 72.24%. The values of ADCdry matter (67.56%) and feed efficiency (64.20%) in treatment C were also higher (P<0.05) compared to treatment B with 57.02% and 54.74% respectively. However, there was no significantly difference (p>0.05) in the value of ADCprotein, ADClipid, and SGR among the treatments. These results indicate the rice bran fermented using A. niger is potential to be used as a raw material ingredient for tilapia feed.

Entire Experiment

A total of thirty-four Czech Fleckvieh (CF), Charolais (CH) and Charolais × Czech Fleckvieh (CH × CF) bulls with an average weight of 284 kg were included in the experiment and fed ad libitum two mixed diets: MS (based on maize silage) and LCS (based on legume-cereal and lucerne silages) with different concentrations of dietary energy until slaughter at the target live weight of 600 kg. The CF bulls consumed more dry matter (DM) of feed daily than the CH bulls (<i>P</i> < 0.05) and gained weight less efficiently than the CH × CF and CH animals (<i>P</i> < 0.01) during the entire experiment. The killing-out percentage was lower in the CF than in the CH × CF and CH (<i>P</i> < 0.05). The CH bulls received a higher score for carcass conformation and a lower score for carcass fatness (<i>P</i> < 0.01) than the CF bulls, had lower proportions of kidney and cod fat (<i>P</i> < 0.01) than the CH × CF and CF bulls, and produced the highest percentage of high-priced meat (<i>P</i> < 0.05) and the lowest percentage of separable fat (<i>P</i> < 0.001). The bulls on the MS diet were younger than the others at the end of the experiment (<i>P</i> < 0.01), gained weight more rapidly (<i>P</i> < 0.001), consumed less DM (<i>P</i> < 0.001) daily, utilized nutrients more efficiently over the entire experimental period (<i>P</i> < 0.001), and had a higher proportion of internal fat than the LCS bulls. It can be concluded that purebred CH bulls were superior to the other breed groups in most of the traits observed. The intensive diet based on maize silage increased average daily gains, reduced the time needed to achieve the target slaughter weight, and improved the feed efficiency of bulls.

The marine species of snapper, Lutjanus analis, has carnivorous eating habits and with potential for cultivation. The aim of this study was to evaluate the apparent digestibility coefficient (CDA) of mutton snapper, and to evaluate its enzymatic profile after feeding with vegetable and animal protein sources. CDA was the indirect method of fecal collection, using chromic oxide as a biological marker. Eight hundred fish, with an average weight of 28.0 ± 2.58 g, were acclimated for 15 days in a net tank (2 m³), ​​and installed in the same collection environment. The acclimatization of 54 fish was carried out in digestibility aquariums (200 L), and the collection of feces started. For mutton snapper, the supply of octopus flour improves (P <0.05) the digestibility of dry matter (CDAMS, 67.17%), crude protein (CDAPB, 90.9%) and crude energy (CDAGE, 78, 8%). Regarding the digestibility of lipids (CDAL), anchovy flour has more (P <0.05) digestible lipids (78.1%), followed by the tested ingredients, fish meal (72.4%) and flour octopus (69.7%). Apparent digestibility of dry matter, crude protein and crude energy were low (P <0.05) for shrimp meal and soybean meal. Mutton snapper fed with octopus flour has higher digestibility coefficients, suggesting this ingredient for species. All diets caused low amylase activity in juveniles, and lipase and alkaline protease activities were higher with the inclusion of broadband anchovy flour and octopus flour, respectively.

And Performance

Supplying the nutritional needs of animals in an economical way is essential to the success of any type of production. The forage palm is a cactaceae well-adapted to semiarid regions and commonly used in the feeding of ruminants. However, studies assessing its use in fishes are scarce. We aimed to evaluate the digestibility of bran from five different forage palm cultivars (Opuntia fícus) in juvenile Nile tilapia and the development of juveniles when receiving increasing levels of the cultivar with the best apparent digestibility coefficient of crude protein (ADCCP) (75.2%). We used 90 masculinized juvenile Nile tilapia (with an average weight of 6.02 ± 0.65 g) in the digestibility experiment to determine the apparent digestibility coefficients of dry matter (ADCDM), crude energy (ADCCP), and crude protein of the cultivars (Orelha de onça, Miúda, Gigante, Comum, and IPA 20). The experimental design was completely randomized (CRD) with five treatments and three repetitions. In the development experiment, 300 masculinized juvenile Nile tilapia (with average weight of 1.39 ± 0.12 g) received feed with different inclusion levels (0, 72, 144, and 216 g Kg-1) of IPA 20 palm bran in a CRD with four treatments and five repetitions. We observed significant differences (P &lt; 0.05) for ADCDM and ADCCP between the treatments. The cultivars that presented the highest ADCDM were IPA 20 (41.75%), Orelha de onça (36.41%), and Gigante (32.59%). For ADCCP, the best cultivar was IPA 20 with 75.2%, followed by Orelha de onça (61.5%), and Miúda (56.1%). As for the performance, the inclusion of IPA 20 palm bran at a rate of 113 g/kg-1 provided the best values in terms of weight gain and final weight in juvenile Nile tilapia.

The objective of this study was to evaluate the associative effect of monensin sodium to virginiamycin and/or essential oils on performance, consumption of nutrients and dry matter, apparent digestibility, feeding behavior and carcass characteristics of feedlot finished steers. The experiment lasted 106 days with 10 days of adaptation and 96-day trial, and had 32 crosses angus steers, average age 12 months and average weight of 376 kg, divided into 16 stalls, the weighing took place every 21 days and at the end of the experiment. The treatments consisted of the combination of the following additives to the diet included: Monensin sodium, 200 mg day-1 (MO); Monensin sodium, a dose of 200 mg day-1 + essential oil dose of 1.5g day-1 (MO+EO); Monensin sodium, a dose of 200 mg day-1 + virginiamycin, 200 mg day-1 (MO+VI); Monensin sodium, 200 mg day-1 + essential oil dose of 1.5g day-1 + virginiamycin day, 200 mg day-1 (MO+EO+VI), each treatment had four repetitions, where each repetitions consisted of a bay with two animals. The MO+VI association in relation to MO only increase in average daily gain (ADG) of 24.44%, 22.35%, 21.10% and 17.31% in weighing 42, 63, 84 and 96 days, similar the combination of MO+EO+VI which provided an improvement of 21.94%, 13.59%, 15.45% and 14.75% respectively in the same weightings. The daily carcass gain and carcass overall gain were higher in associations MO+VI and MO+EO+VI and provided an average gain of 16.67 kg more compared to MO and MO+EO. In the parameters feed efficiency, dry matter intake and nutrient expressed in kg day-1 and percentage of live weight were not observed differences (P > 0.05) between treatments. Data on apparent digestibility, feeding behavior and carcass characteristics did not show statistical difference between treatment, except for fat thickness which was higher when associated with any of the additives to the MO, and farm weight was higher in associations containing VI. Associating MO+VI or MO+EO+VI proved to be best in this work compared to MO+EO or only MO in the diets of steers in termination.

ABSTRACTObjective. Evaluate the effect of increasing P intake on nutrient digestibility, and compare the true and apparent absorption coefficients of P and Ca in lambs. Materials and methods. Twenty-four Santa Ines sheep, with an average weight of 33.6 ± 1.6 kg, were distributed into four treatments (0, 2, 4 and 6 g/day of supplementary P) with forage: concentrate ratio of 70:30. The study of apparent nutrient digestibility was conducted during the first week, using the total feces collection method. During the second week, after injection of 7.4 MBq of 32P and 7.7 MBq of 45Ca, apparent (AAC) and true (TAC) absorption coefficients of P and Ca were determined. The lambs were kept in metabolic cages. Results. The increase in P intake did not affect (p>0.05) dry matter, crude protein, NDF or ADF digestibility, but the TAC of P and Ca and mineral matter digestibility decreased. The AAC was not affected (p=0.10). A cubic relationship was observed between P intake and TAC (TAC=2.16–1.95X+0.55X2-0.04X3; R2=0.38) and linear relationship with the TAC of Ca (TAC=0.559–0.03X; R2=0.26). TAC and AAC values were different (p<0.001). Conclusions. The increase in P intake doesn’t impact organic matter digestibility, but does affect P and Ca absorption. Apparent digestibility is not a reliable parameter to determine the efficiency of P and Ca absorption.

Mechanically Separated Meat (MSM) is an alternative for the diversification of new fish-based products and also as a solution for the use of waste from the filleting industries. Tilapia MSM was used in this study for the formulation of a fish spread aimed at investigating its acceptability by consumers. Two spread formulations were prepared with different types of commercial salt: seasoned salt (A) and common salt (B). The consumers (112) evaluated their acceptance with respect to overall impression, spreadability, appearance and flavour acceptability on a 9-point hedonic scale. A microbiological analysis of the Tilapia MSM was also carried out and the chemical composition of the Tilapia MSM-based spread determined. When considering the acceptance of all the consumers, the overall impression, appearance and flavour were significantly (P < 0.05) lower for the spread made with common salt (B). However, three different consumer segments could be found from the overall impression of the Tilapia MSM-based spread. The largest segment also preferred the spread made with the seasoned salt (A), but both products were well accepted. The tilapia MSM presented adequate quality as a raw material according to the technical regulations for microbiological standards. The final product presented the following chemical composition: moisture - 62.17%; ash - 2.11%; protein - 9.75% and lipid - 18.81%. These results could be of great importance for the industry in developing and marketing new products obtained from mechanically separated Tilapia meat.
