This study evaluated the effect of enriched artemia nauplii with commercial probiotic for angelfish larvae determining productive performance, intestinal modulation and survival. Therefore, it experiment occurred in completely randomized design with five treatments (T1- 0.0, T2- 1.5, T3- 3.0, T4- 4.5 and T5- 6.0g of commercial probiotic) and four replaces during 20 days. After larvaculture, post larvae passed by biometric procedures to determine productive performance and then microbiological analysis. Occurred reduction of total heterotrophic bacteria while increased lactic acid bacteria in the intestinal tract from the post larvae for treatments T3, T4 and T5. The commercial probiotic also increased the survival and performance as final weight, weight gain and specific growth rate. For these reasons, the use of 3g of commercial probiotic promotes greater performance and intestinal modulation for angelfish larvae.

Filial Behavior

Mortality of perinatal lambs and low weight at weaning cause huge liabilities to farmers. Current study describes maternal-filial behavior and evaluates the use of maternal behavior score (MBS) to estimate the behavior of ewes and lambs soon after birth, and correlate it with lamb mortality and performance during lactation. Thirty-seven Corriedale ewes were used in a completely randomized design. MBS was assessed up to 24 hours after birth, taking into consideration the distance of the ewe from the lamb at the approach of a person. Maternal behavior, placental weight, weight gain of the lambs until weaning and their survival rate were also evaluated until two hours after lambing. More than 90% of the ewes had adequate maternal behavior, with parental care, even though ewes were very sensitive to the presence of people. There was no significant correlation between MBS and maternal behavior, lamb mortality rate and live weight gain. Under these conditions, MBS was not a useful tool to estimate maternal behavior and performance of lambs.

Probiotic Effect

ABSTRACT: The aim of this research was to evaluate the changes in intestinal tract microbiota, hematological parameters and zootechnical indexes of yellowtail lambaris (Astyanax bimaculatus) fed with different probiotic supply frequencies (Lactobacillus spp.). Lambaris (1,200) were distributed in twelve boxes, divided in three treatments, 100% supply; 25% and 0% (control) of feeds supplemented with probiotic. After 87 days, fish fed with supplemented diet, regardless of frequency (100% and 25%), showed an increase in the total lactic acid bacteria count of 7.99±0.15 log CFU mL-1 and 7.04±1, 29 log UFC mL-¹ respectively, in the intestinal tract and decrease of Pseudomonas spp. in both 100% and 25% (4.09±0.84log UFC mL-1 and 4.00±1.12log UFC mL-1, respectively) in relation to the control treatment (6.74±1.04log UFC mL-1). Fish fed with 100% of diets supplemented with probiotics had a higher leukocyte count (47.7±6.7x103μL-1), lymphocytes (36.0±2.6x103μL1), monocytes (12.0±4.2x103μl-1), as well as higher mean final weight (10.60±0.89g) and weekly growth rate (0.80±0.08g.week-1) than the other treatments (25% of probiotic offered and control). Probiotic (Lactobacillus spp.) offered in 25% of feeds (or more) alters the yellowtail lambari microbiota (A. bimaculatus); however, must be offer in 100% of feeds to improve the hematology profile and productive performance.

The objective of this work was to evaluate the productive performance of broccoli under different top-dressing organic fertilizations. The experiment was conducted under protected cultivation, in a completely randomized design with four replications, with two plants per experimental unit. Broccoli seedlings were produced in a commercial substrate in styrofoam trays. The seedlings were transplanted to plastic pots containing 10.0 L of substrate made up of subsoil and organic compost at the ratio of 3:1 (v/v), respectively, which is equivalent to about 20.0 t ha-1 of organic compost at planting. After seedling establishment, the top-dressing fertilization treatments were applied: gliricidia biomass associated or not with liquid biofertilizer of cattle manure to the soil and bokashi. Two control treatments were established: one with mineral fertilization recommended for the crop and the other without top-dressing fertilization. The broccoli production was evaluated (commercial standard). Plants that received mineral fertilizer were more productive, however, they were not significantly different (p>0.05), by Dunnet test, from the plants fertilized with 2.5 t ha-1 gliricidiabiomass (dry mass) associated with liquid biofertilizer (2.0 L m-2) applied to soil. Top-dressing fertilizations with only gliricidia, at 2.5 and 5.0 t ha-1 of biomass (dry mass), resulted in no significant increase in production of broccoli inflorescence. The use of bokashi in addition to gliricidia biomass and liquid biofertilizer reduced the efficiency of the fertilization compared with plants that received only gliricidia and liquid biofertilizer.

The objective of this experiment was to determine the effects of feeding rabbits with Maxigrain® (M) enzyme supplemented Gliricidia sepium leaf meal (GLM) on their physiology, performance characteristics, and nutrients digestibility. Twenty weaned rabbits of mixed sexes, 5-6 weeks old, were randomly allotted to five dietary treatments including 0 g M which was soybean without M (control) and GLM supplemented with M at 50, 100, 150 and 200 g M per kilogramme of GLM. There were four rabbits per treatment and one rabbit as replicate in a completely randomized design. There were no significant (p > 0.05) treatment effects in all physiological and performance indices as well as those of crude fat, fibre and NFE digestibilities. There were variations (p < 0.05) due to the treatment effects on dry matter, crude protein and ash digestiblities. This implies that the feeding of soft faeces directly from the caecum called coprophagy mechanism in rabbits has its concomitant nutritional benefits. This advantageous benefit can enable rabbit to effectively and efficiently utilize forage or forage-based diet with or without enzyme supplementation.

The objective of this study was to evaluate the effect of different prey concentrations (50; 100; 150 and 200 artemia nauplii post-larvae-1 day-1) and salinized water (0; 1 and 2 g L-1) on larviculture of Pyrrhulina brevis, an Amazonian ornamental fish. The experiment was carried out in a completely randomized design, in a 4x3 factorial design, with three replicates. A total of 360 post-larvae were randomly distributed in 36 aquariums (1L), to 10 post-larvae L-1. At the end of the experimental period (15 days) the post-larvae were measured, weighed and counted. No interaction was identified between the prey concentrations and salinized water for all evaluated parameters. The best growth results, both for length and weight, were observed in the post-larvae that received 150 and 200 artemia nauplii post-larvae-1 day-1, while the lower survival rate was observed in post-larvae fed 50 and 100 artemia nauplii post-larvae-1 day-1. The final length and length gain were higher when the post-larvae were reared in salinized water at 1 and 2 g L-1, while the final weight, weight gain and specific growth rate were higher in post-larvae submitted to 1 g L-1 of salinized water. The uniformity of the batch for weight and length of the fish showed no significant difference, independent of the prey concentrations and salinized water used. Thus, the supply of 150 artemia nauplii post-larvae-1 day-1 in salinized water at 1 g L-1 is recommended during the first fed of Pyrrhulina brevis.

Enzyme Complexes

Two experiments were carried out to investigate the effect of “on top” addition of different enzyme complexes, the enzyme α-galactosidase and three sources of the enzyme phytase available on the market, in broiler diets. In the first experiment, 1260 one-day-old Cobb 500® chicks were distributed into seven treatments in a completely randomized design (CRD) with six replicates and 30 birds/replicate. Treatments consisted of combinations of different enzyme complexes, namely, complex A (phytase, protease, xylanase, ß-glucanase, cellulase, amylase, pectinase), complex B (protease and cellulase) and complex C (xylanase, amylase and protease); isolated α-galactosidase (GAL); and three sources of phytase (P1, P2 and P3) in the diet. The treatments were formulated as follows: T1 - basal diet (BD); T2 - BD + enzyme complex A + enzyme complex B (BDAB); T3 - BDAB + GAL; T4 - BD + complex A + GAL; T5 - BD + complex C + P1 + GAL (BDCG); T6 - BDCG + P2; and T7 - BDCG + P3. The following variables were measured in the experimental period of 42 days: feed intake (FI), weight gain (WG), average final weight (AFW), feed conversion (FC), and carcass yield. Significant differences occurred for AFW, WG and FC in the pre-starter phase. In the second experiment, 112 Cobb 500® chicks aged 25 days were distributed into seven treatments in a CRD with four replicates and four birds/replicate. Treatments were the same as in the first experiment. Nutrient digestibility was evaluated in an experimental period of seven days. Differences were found in the metabolism coefficient of ether extract (MCEE). Dietary inclusion of enzyme complexes improves the AFW and WG of chickens from 1 to 7 days of age and MCEE in the grower phase.

Hasil penelitian menunjukkan arah irisan berpengaruh terhadap berat kering simplisia, sedangkan interaksi antara tebal dan arah irisan tidak berpengaruh terhadap berat kering simplisia umbi garut. Arah irisan berpengaruh terhadap berat kering dan performa simplisia umbi garut, tebal irisan berpengaruh terhadap rendemen flavonoid. Crude simplisia is natural material for making medicine, which has not undergo processing, packing, drying and saving. Slicing is an important step in making medicine because in this process the loss of some parts could ease the process of packing and milling. Slicing could be done diagonally or longitudinally. A Different way of slicing could affect this simplisia. This study aimed to examine the influence of slicing direction, the thickness of slices, and its combination on the dry weight and the performance of arrowroot. This research was conducted in the Laboratory of BSF Tumbuhan UNIDIP. The design used was Completely Randomized Design with combination treatment of thickness (3mm and 5mm) and slice direction (diagonally and longitudinally). The parameter of this research used dry weight by weighing after the drying process and the performance (by measuring color, hardness, and the aroma of dried simplisia). The data analysis used Analysis of Variance. The findings showed that slice direction influenced the weight loss on simplisia, but the interaction did not influence on the dry weight of arrowroot simplisia. Slice direction affects dry weight and performance of arrowroot simplicia, slice thickness affects flavonoid yield.

Abstract The objective of this work was to evaluate the effects of dietary supplementation with fructooligosaccharides (FOS) on the performance, hematology, and immunology of pacu (Piaractus mesopotamicus) juveniles. A total of 0 (control), 2.0, and 4.0 g kg-1 of the probiotic were added to the fish diets. Fish (49.3±4.3 g) were allotted into 12 tanks of 60 L, in a completely randomized design (n=4). After 60 days, final weight, weight gain, specific growth rate, and feed conversion ratio were improved in the fish fed with the prebiotic, although feed intake was not affected by the treatments. The number of red blood cells was higher only in fish fed with 2.0 g kg-1 FOS. The opposite was observed for the hematimetric indices mean corpuscular volume and mean corpuscular hemoglobin, which decreased in fish fed with 2.0 g kg-1 FOS. The number of defense cells, such as leukocytes and thrombocytes, also increased in the prebiotic treatments. The evaluated immunological parameters were not influenced by prebiotic supplementation. Dietary FOS supplementation improved pacu growth and health.
