“…The amount of ash was higher at 50 and 75 mg/kg treatments, which shows the important physiological role of astaxanthin in calcium and lipid metabolization. This is consistent with the findings of Faghani et al (2013) on the addition of astaxanthin to beluga diet.…”

“…The amount of body lipid decreased with increasing levels of nanoliposome-coated astaxanthin, which is consistent with the results of Faghani et al (2013) on the addition of astaxanthin to beluga (Huso huso) diet. The main reason is the synthesis and metabolism of lipid by encapsulation of astaxanthin in liposomes (Rehulka, 2000).…”

“…There was no significant difference in moisture in different treatments compared to the control treatment (p > 0.05). Faghani et al (2013) reported a similar result from the addition of astaxanthin to beluga (Huso huso) diet. Inconsistence between the results of the present study and other reports regarding the moisture may be due to differences in the composition and percentage of active ingredient in different additives, as well as differences in the species of interest, their size and growth stage.…”

The purpose of this study was to investigate the effect of different levels of nanoliposome-coated astaxanthin (NA) on growth performance, body proximate composition, liver enzyme activities and pigmentation in rainbow trout (Oncorhynchus mykiss). Groups of fish weighing 31 ± 2 g each in three replicates (30 fish per replicate) were fed with 0, 25, 50, 75 and 100 mg/kg nanoliposome-coated astaxanthin for 60 days. At the end of the experiment, growth performance including final weight, weight gain (WG), feed conversion ratio (FCR), specific growth rate (SGR), survival rate (SR), daily growth rate and condition factor (CF), body crude protein, fat, ash and moisture, liver enzymes (ALT and ALP) and pigmentation (skin and muscle carotenoids and muscle astaxanthin) were measured. The results showed that the addition of NA had a significant effect on growth indices (p < 0.05). The highest final body weight (FBW) (101.46 ± 4.46 g) was related 75 mg/kg NA, and the lowest FBW (93.10 ± 0.96 and 91.98 ± 4.08 g) was seen in control and 100 mg/kg NA respectively (p < 0.05). Also, the highest amounts of protein and ash were measured in 50 and 75 mg/kg NA treatments, while the lowest levels of these occurred in control and 100 mg/kg NA. The highest amount of serum ALT and ALP enzymes was in 100 mg/ kg nanoliposome-coated astaxanthin treatment, and the lowest amount of ALT enzyme was in 50 mg/kg treatment. Also, the lowest amount of ALP enzyme was obtained in control treatment. The concentration of carotenoids in skin and fillet and fillet astaxanthin increased significantly by adding nanoliposome-coated astaxanthin to the diet (p < 0.05). The highest carotenoid quantity of skin and fillet and astaxanthin fillet was observed in fish fed 75 mg/kg nanoliposome-coated astaxanthin and the lowest amount in the control group. These results suggest that the incorporation of nanoliposome-coated astaxanthin into rainbow trout diet at the level of 75 mg/kg can have a positive effect on growth indices, reduced liver enzyme activity and improved skin and fillet pigmentation.

“…O milho apresenta amido de menor degradabilidade no rúmen quando comparado com a raiz de mandioca (ZEOULA et al, 1999), mas por estar finamente moído pode ter tido a degradabilidade aumentada, se aproximando à digestibilidade da raiz de mandioca. Medina et al (2009) observaram maior digestibilidade da dieta constituída de silagem de maniçoba e milho triturado quando comparada com a mesma silagem acrescida de raiz de mandioca ou farelo de palma. Estas últimas apresentaram resultado de digestibilidade aparente semelhante, os autores atribuem este resultado à baixa digestibilidade in vitro da silagem de milho que em combinação com os alimentos diminuiu a digestibilidade dos nutrientes, além disso, diferentemente da raiz de mandioca utilizada neste experimento com 6,88% da FDN e 4,62% da FDA, apresentava alto teores destas frações (29,29 e 24,05%, respectivamente).…”

“…It presents nutrient-rich tubers, which allow it to resume growth after the first rains of the short annual rainy season MOREIRA FILHO et al, 2008;SOUZA et al, 2006). Its senesced leaves are consumed by animals; however, when they are green and photosynthetically active, they contain cyanogenic glycosides in levels that are toxic to ruminants (COSTA et al, 2008;FRANÇA et al, 2010;MEDINA et al, 2009). The quantity of these cyanogenic glycosides is reduced to non-toxic levels (43% or less of the original content) by cutting of fresh fine stems and leaves.…”

The growth and forage production of Manihot glaziovii were evaluated in plants growing in Itapetim-PE, Brazil via a complete block experimental design with four treatments (0, 33, 50, and 100% branch cutting intensity) to analyze increases in height and diameter. Furthermore, 3×2 factorial treatments (three branch cutting intensities: 33, 50, and 100% as well as two types of collected forage material: Branches with diameter < 10 mm and corresponding sprouts on the same branches 1 year after being cut) were analyzed for improvement in forage quantity and quality parameters. Height increase was affected (P < 0.05) by branch cutting intensity (0.29, 0.11, 0.43, and -0.04 m plant -1 , respectively, for 0, 33, 50, and 100% branch cutting intensities), while the increase in diameter was not affected (P > 0.05) (3.97 mm plant -1 was the overall mean increase). Cutting intensity×type of collected material, in combination, affected (P < 0.05) the quantity of the collected forage: means were considered similar (P > 0.05) in the first (branches) and second (sprouts) forage collection events for 33% (0.66 and 0.75 kg dry matter plant -1 , respectively) and 50% (1.40 and 1.73 kg dry matter plant -1 , respectively) cutting intensities; it decreased (P < 0.05) from the first to the second collection events, when 100% of branches and sprouts were harvested (3.37 and 2.06 kg dry matter plant -1 , respectively). The combined effects of aforementioned parameters were observed (P < 0.05) as interactions for some forage quality variables. Neutral detergent fiber content remained constant (P > 0.05) between 50.57 and 54.41% in forage containing branch and sprouts from 33 and 50% cutting intensities. It increased (P < 0.05) to 62.20% in sprouts from 100% cutting intensity. Acid detergent fiber content increased (P < 0.05) from around 38.4% to 46.63% in sprouts from plants subjected to 100% cutting intensity. The crude protein (between 8.72 and 10.08%) and ether extract (between 2.74 and 4.35%) contents were unaffected (P > 0.05) by these factors. Mineral matter content was higher (P < 0.05) in sprouts from all cutting intensities with 5.9% being the highest. Up to 50% of Manihot glaziovii branches with Ø < 10 mm and corresponding 1-year-old sprouts can be pruned with no negative effect on the quality and quantity (up to 1.73 kg dry matter plant -1 ) of the collected forage.

ResumoO crescimento e a produção de forragem de Manihot glaziovii foram avaliados em plantas se desenvolvendo em Itapetim-PE, Brasil, através de um experimento no delineamento em blocos casualizados com 4 tratamentos (intensidades de corte dos ramos: 0, 33, 50 e 100%) para analisar o aumento em altura e diâmetro. Adicionalmente, foram considerados3x2 tratamentos fatoriais (três intensidades de corte dos ramos: 33, 50 e 100%, e dois tipos de material forrageiro coletado: Ramos com diâmetro < 10mm e respectivas rebrotas desses 1 ano após serem cortados) para analisar parâmetros de quant...
