    Aquaculture is essential for food security and the yellowtail lambari is of great importance in Brazilian fish farming. Zophobas morio meal has emerged as a sustainable protein alternative for fish diets. This study evaluated the apparent digestibility of larval, pupal and adult meal of Z. morio in diets for lambari. The experiment, conducted at IFES and UFES, used 840 juvenile lambari. The animals were fed three times a day and feces were collected by the direct method eight times a days over a period of 22 days. The apparent digestibility coefficients (ADCs) for larva and pupa meal were significantly higher than the ADC for adult meal, due to their lower chitin content. Protein digestibility was highest for pupa meal, followed by by larva and by adult meal. Lipids of larva meal were more digestible than those of adult meal. There was greater gross energy utilization for larva and pupa meal than for adult meal. In conclusion, Z. morio meal is a promising feed for yellowtail lambari, especially that of the larval and pupal stages, due to its good digestibility and high nutritional value; adult meal has lower digestibility and requires additional treatments for improvement.

    Pacu (Piaractus mesopotamicus) is a fish with a high production potential in Brazil. However, one limitation is the excessive amount of ether extract in its carcass, an undesirable characteristic for the consumer. One approach to overcome this limitation is to improve carcass quality through zootechnical additives such as caffeine. The aim of this study was to evaluate the effect of supplementing the diet of pacu with caffeine on cut yield, biological indices, and carcass composition. Two hundred pacu with an initial weight of 1,687 g were used. The animals were allocated to 20 aquaculture cages of 1 m³, with 10 animals per cage. A completely randomized design with four treatments and five replicates was used. The treatments evaluated consisted of four inclusion levels of caffeine: T1 = 0.00 g; T2 = 0.16 g; T3 = 0.32 g, and T4 = 0.48 g caffeine.kg-1 of feed. The findings show that caffeine can be recommended as a diet supplement for carcass improvement of pacu, reducing the fat content and increasing the protein content of the carcass. Caffeine up to 0.32 g.kg-1 of feed can be added to the diet of pacu without affecting its performance or cut yield.

    This work evaluated the influence of vitamin A on performance, organ weight, and bone and skin characteristics in broilers (Cobb 500) at 21 and 42 days of age. A total of 1920 chickens were distributed in a randomised design, considering six vitamin A supplementation levels (0, 6000, 16,000, 26,000, 36,000, and 46,000 IU kg−1), with 16 replicates and 20 chickens per experimental unit, established due to rising the range of vitamin levels observed in the literature to evaluate the effect of vitamin A on broilers. At 22 days, half of the replicates from each treatment continued receiving the initial diet, and the other eight repetitions received diets without vitamin A (0 IU kg−1) until 42 days. The level of vitamin A influenced feed intake (FI) and body weight gain (BWG) until 21 days for all treatments. Broilers at 21 days of age had a more significant BWG at a vitamin A supplementation level of 28,209 IU kg−1. At 42 days, vitamin A influenced the BWG and FI of broilers at treatments that were not supplemented after 21 days. Treatments supplemented up to 42 days showed quadratic responses to vitamin A for BWG, FI, and feed conversion. The vitamin A levels influenced the relative weights of the small intestine, pancreas, gizzard, abdominal fat, Seedor index, and breaking strength at 42 days, where the adequate supplementation of vitamin A improved these characteristics in broilers. Vitamin A supplementation from 22 to 42 days old did not affect broiler performance. An increased BWG was obtained when vitamin A supplementation occurred until 42 days, with supplementation of 29,375 IU kg−1 and a lower response of feed conversion with the addition of 27,775 IU kg−1.

    Chicken broilers digestibility and performance fed with different ME levels, with and without adjustments of digestible lysine, calcium, and available phosphorus, were evaluated. For digestibility, 210 male Cobb 500 chicken broilers were used and distributed into a 3x2+1 factorial arrangement, with three ME levels (3050; 3125 and 3200 kcal/kg) with and without nutrient adjustment, plus one control treatment (2975 kcal ME/kg), totaling seven treatments including six repetitions with five birds into each repetition. For initial performance, 1120 birds were distributed randomly with eight replications within treatments and 20 birds for each replication. For final performance, 1008 chickens were distributed with eight replications and 18 birds for each replication. The DCDM and DCCP were improved (P<0.05) according to the increase of ME and the adjustment in dietary nutrients, as well as GE digestibility. The final performance showed no interaction (P>0.05) between energy and nutrient adjustment, but the increase in energy levels improved the feed conversion ratio (FCR=1.370). Increasing energy density with nutrient adjustment improves both nutrient utilization and bird performance.

    Animal Production Science, 2022
    Context The feeding of pigs raised in an intensive system has been made, in general, with rations formulated using corn and soybean meal as the main ingredients. Brown rice bran, a by-product of the processing of rice grains for human consumption, presents itself as an alternative for total or partial replacement. Aims The objective of the present study was to observe the effects of including 10% of whole rice bran (WRB), adding 0.02% exogenous multienzyme complex (MC) and changing the levels of metabolisable energy and available phosphorus (ME.aP) together in rations for newly weaned piglets. Methods Digestibility and metabolisability of the rations, as well as zootechnical performance, were evaluated using 24 and 144 animals respectively, distributed in randomised blocks in time, with eight treatments, in a 2 × 2 × 2 factorial scheme. Three repetitions were used in the metabolism essay, with one animal housed per cage, and six repetitions were made in the performance test, with three animals per stall, which was considered the experimental unit. Digestibility and metabolisability coefficients, weight gain and feed intake, as well as feed efficiency, were evaluated. Key results The results showed that the inclusion of WRB reduced the digestibility and metabolisability coefficients of the rations, while the addition of MC provided an improvement in these indexes. The performance test showed that the inclusion of WRB worsened (P &lt; 0.05) the feed efficiency. Conclusions and implications The multienzyme complex improves the digestibility and metabolisability of experimental rations, although it does not influence the performance of piglets in the nursery phase.

    Objetivou-se estimar a exigência de energia metabolizável (EM) para suínos machos imunocastrados na fase de terminação. O experimento foi conduzido na Universidade Estadual Norte Fluminense Darcy Ribeiro. Foram utilizados 60 suínos machos distribuídos em delineamento de blocos casualizados, sendo 50 suínos imunocastrados – IM (tratamento 1 a 5) e 10 castrados cirurgicamente – CC (tratamento 3b). Os tratamentos diferiram quanto ao nível de EM utilizada, sendo T1 – 3030, T2 – 3130, T3a – 3230, T3b – 3230, T4 – 3330 e T5 – 3430 Kcal de EM/Kg. Foram avaliadas características de desempenho em diferentes períodos (A – intervalo entre a primeira e a segunda imunização, B – intervalo entre a segunda imunização e o abate e T – período total, da primeira imunização ao abate) e de carcaça, além de análise sensorial da carne dos suínos. Os dados médios obtidos nos diferentes níveis de energia foram submetidos à análise de variância e análise de regressão linear em nível de 5% de significância. A análise foi realizada com o auxílio do programa de análises estatísticas SAEG. Foi observado efeito linear crescente (P&lt;0,05) para consumo de ração diário, ganho de peso diário, consumo diário de energia e consumo diário de lisina em diferentes períodos. Houve resultados significativos (P&lt;0,01) para consumo diário de energia e consumo de lisina em diferentes períodos. Não houve diferença (P&gt;0,05) entre as características de carcaça avaliadas. Na análise sensorial, embora os avaliadores tenham detectado diferenças no odor das carnes de suínos CC e IM, tais diferenças não foram devidas ao odor sexual. Não foi possível estimar o nível de energia metabolizável para a categoria de suínos imunocastrados em fase de terminação.

    This study aimed to evaluate the use of acacia tannin as a toxic metal adsorbent in the diets of broilers fed with the inclusion of golden mussel meal in substitution for calcitic limestone. In the first trial, 648 male 21-day-old animals were divided among six treatments and six replicates, with 18 birds per experimental unit, organized in a completely randomized design (DIC). The treatments were diets with different acacia tannin levels (0, 250, 500, 750, 1000, or 1250 g ton-1). The results indicated that 250 g ton-1 of tannin was not harmful to weight gain, final weight, or feed conversion. Tannin levels caused a decrease in carcass yield and fat deposition and an increase in liver size. For the second trial, 900 male broilers of 21 days of age were used and distributed in a DIC, with different levels of substitution of calcitic limestone by the golden mussel meal (0, 25, 50, 75, or 100 %) and supplementation or not with acacia tannins (250 g ton-1), with 5 replicates and each experimental unit being composed of 18 birds. The performance data show that the use of 250 g ton-1 of tannin is detrimental to bone performance and resistance and golden mussel meal can be used to substitute up to 100 % of the limestone in the diets without affecting the variables studied.
