“…Indeed, the multivariate analysis of variance showed that each of the Pillai's Trace, Wilks' Lambda, Hotelling Trace and Roy's Largest Root statistical test demonstrated that there is a significant effect of the treatments composed of the mixture of organic and inorganic fertilizers on the average number of leaves and the average height of L. sativa L., since p < 0,05, at the α = 0,05 level. However, the results diverge from other studies that evaluated multiple response variables with one, two and three factors and did not apply multivariate analysis of variance, either in classical designs or in factorial experiments (Muscolo et al, 2022;Pizarro et al, 2019). When performing the univariate analysis of variance in a complete randomized design, it was determined that the factor composed of organic and inorganic fertilizers significantly influenced both the average number of leaves and the average height of L. sativa L., since a p < 0,05 was obtained.…”

The objective of this research was to evaluate the multivariate effect of organic and inorganic fertilizer mixtures on growth of Lactuca sativa L. For this purpose, a complete multivariate randomized design was performed, with 5 replicates in 20 parcels, to which the treatments were randomly distributed. The data on the number of leaves per plant and the height of lettuce was obtained at harvest in the study field where the experiment was conducted. The compliance with the basic assumptions of normality and multivariate homogeneity of the experimental residuals was significantly demonstrated, evidencing the adequacy of the model. Likewise, the levels of organic and inorganic fertilizers had significant effects on the number of leaves and height of the lettuce plant collectively and individually.

“…However, the physical and chemical composition of raw poultry was described by several researches while the color of the waste were grayish to black according to their states and the odors generated were due to the presence of volatile organic compounds (VOCs), ammonia (NH 3 ), hydrogen sulfide (H 2 S), greenhouse gases, and particulate matter (Kopec´ et al, 2018;Kalus et al, 2017;Passos et al, 2014;Yetilmezsoy and Sakar, 2008). The semi-solid texture of raw poultry waste comprised a pH value of above 7.5, referring the alkaline condition of the material (Pizarro et al, 2019;Finch et al, 2014). The total suspended solid of poultry waste was reported 5,020 ± 380 mg/L in the research of Yetilmezsoy and Sakar (2008), however the present study suggested the range can be varied from 8854-8864 mg/L due to the mixture of the other organic particles with the raw poultry waste.…”

The fly larvae (Lucilia sericata) are being used as an alternative protein source in any kind of animal feed as it reduces the cost of preparation of feed. This current study focused on the physico-chemical and proximate properties of raw poultry waste, while this study also revealed the production process of fly larvae and the proximate composition of it. The poultry waste was collected from Suvro poultry farm, Sutiakhali, Mymensingh, then the physic-chemical properties of the raw poultry waste were determined using different procedures. Three treatments were considered for production of fly larvae, T1 (3 kg), T2 (6 kg) and T3 (9 kg) in a 15 kg capacity tray with three replications. After production, the proximate composition were also measured of fly larvae. Physico-chemical properties such as, color, odor, texture, temperature, pH, total solids (TSS+TDS), chemical oxygen demand, dissolved oxygen, alkalinity, available N, available P, and fiber in raw poultry waste were determined and presented. Proximate composition such as, moisture, total N, total P, available N, total Ca, ash and crude fiber were found in significant amount in the poultry waste. It was found that T3 (1350±68g) produced highest volume of live maggot compared to the other treatments, but T2 (17.50±1.10%) produced highest percentage volume. The proximate compositions of fly larvae were assessed and found 56.60±0.25% protein value in it, suggesting that fly larvae could be the protein replacer in fish feed. The result of this study revealed cheap protein source in aquaculture production, such as production and rearing of stinging catfish Heteropneustes fossilis, and the findings might be helpful for cost reduction in aquaculture operation.

“…Poultry litter is generally used as a low-cost organic fertilizer, as it is an important source of nitrogen, phosphorus and trace elements for crop production, and has been shown to be effective in improving physical and biological fertility of crops ( Bolan et al, 2010 ; Cheng and Jiang, 2014 ; Pizarro et al, 2019 ). In some countries it is also used as an input in the formulation of diets of other productive species, as it constitutes a good source of protein, energy and minerals ( Cornejo et al, 2019 ) especially for cattle, which due to its digestive characteristics, can make a more efficient use of nutrients ( Cabrera-Núñez et al., 2018 ).…”

Antimicrobials are currently used in poultry for disease treatment. However, their excretion in bird feces may contaminate the environment. Considering this, the objective of this work was to quantify antimicrobials residues concentrations in therapeutically treated broiler chicken droppings throughout the post-treatment period. For this aim a multiresidue method using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was validated. Forty-eight male broiler chickens were distributed and treated with commercial formulations of 5 different antimicrobials. Results showed that oxytetracycline and 4-epi-oxytetracycline, presented the highest concentrations during all sampling period, detecting concentrations of 1471.41 µg kg −1 at the last sampling point (day 22 post-treatment). Florfenicol, tylosin, enrofloxacin, and ciprofloxacin were eliminated and detected in treated chicken droppings until d 18 post-treatment. Sulfachloropyridazine decrease gradually during post-treatment period until day 30. Results demonstrate that studied antimicrobials in treated chicken droppings were eliminated for prolonged periods, therefore becoming a significant route of residues dissemination into the environment.
