RESUMO: Objetivou-se avaliar a substituição da suplementação da ractopamina pelo uso dos óleos de coco ou cártamo nas dietas de suínos em terminação. Foram utilizados 24 suínos machos castrados mestiços com peso médio de 78,00±8,76 kg, distribuídos em um delineamento de blocos casualizados, contendo quatro tratamentos e seis repetições compostos por: Ração Basal (RB); RB + 10 ppm de ractopamina; RB + 4 cápsulas de 1 grama cada de óleo de cártamo e RB + 4 cápsulas de 1 grama cada de óleo de coco. Na avaliação do desempenho foi observado o efeito (P<0,05) da suplementação das dietas com óleo de cártamo, ractopamina e coco no ganho de peso e conversão alimentar. As variáveis relacionadas com as carcaças também foram afetadas pelos tratamentos (P<0,05), sendo a espessura de toucinho 3 (ET3) reduzida pelo uso do óleo de cártamo, ractopamina e coco. Na avaliação da área de olho de lombo foram observados efeitos positivos (P<0,05), com maiores valores para os tratamentos suplementados com ractopamina, óleo de coco e com óleo de cártamo, quando comparados com a dieta controle. As dietas também afetaram o perfil dos ácidos graxos (P<0,05) de forma positiva, com a redução do ácido míristico do toucinho nas dietas com ractopamina e óleo de cártamo e aumento na deposição dos ácidos graxos palmitoleico e oleico do lombo nas dietas suplementadas com óleo de coco e cártamo, respectivamente. Conclui-se que tanto o óleo de coco quanto o de cártamo podem ser utilizados como substitutos da ractopamina.

ABSTRACT: The objective of this study was to explore the substitution of ractopamine by coconut or safflower oil in finishing pig diets. The study included 24 crossbred barrows weighing 78.00 ± 8.76 kg distributed in a randomized block design with four treatments and six replicates composed of: basal ration (BR), BR + 10 ppm ractopamine, BR + four 1 g capsules of safflower oil, and BR + four 1 g capsules of coconut oil. Performance evaluation showed that safflower oil, ractopamine, and coconut oil supplementation had a significant effect (P < 0.05) on weight gain and feed conversion. Carcass-related variables were also affected by the treatments (P < 0.05), with fat thickness 3 (FT3) reduced by the use of safflower oil, ractopamine, and coconut oil. Rib eye area was positively affected (P < 0.05) by diet, with ractopamine, coconut oil, and safflower oil supplementation treatments showing higher values than control diet treatment. The diets also affected fatty acid profiles (P < 0.05), with decreased myristic acid content in animals supplemented with ractopamine and safflower oil and increased deposition of palmitoleic and oleic acids in animals supplemented with coconut oil and safflower oil, respectively. Results suggested that both safflower oil and coconut oil can be used as substitutes for ractopamine.

ABSTRACT The objective of this study was to evaluate the effect of the inclusion of canola and coconut oils to diets of European quail (Coturnix coturnix) over performance and carcass yield. One hundred and ninety-two quail (eight-days old) were randomly allocated to four dietary treatments with six replicates of eight birds each. The treatments were arranged in a factorial 2×2 scheme with two sources of dietary oil containing two levels of canola and coconut oils (1 and 2%). For performance variables, the final weight was evaluated, and the carcass variables were feed intake, weight gain, and feed conversion. A significant difference was observed between treatments for feed intake, with the inclusion of 2% canola oil providing higher intake. There was also significant effect for carcass characteristics on weight at fasting, eviscerated carcass, liver and gizzard weights, as well as liver, heart, and gizzard yields. The inclusion of vegetable oil such as canola and coconut oils in diets for European quail at the levels of 1 and 2% can be performed with no negative effect on performance from 8 to 42 days of age.

ABSTRACT The purpose of this study was to evaluate the effects of qualitative dietary restriction diet on carcass characteristics, meat quality, fatty acid profile, and performance of finishing pigs fed diets containing cashew bagasse bran. Forty pigs (20 females and 20 males) with initial weight of 60.00±5.24 kg of body weight (BW) were used. The diets were formulated with corn, soybean meal, cashew bagasse bran, vegetable oil, and mineral and vitamin mixture for finishing pigs. The experimental design was in randomized blocks with five treatments and four replicates, with two animals per experimental unit, one of each sex. Parameters related to performance, carcass characteristics, meat quality, and fatty acids profiles were used. The treatments used in the experiment did not affect feed intake and daily weight gain; however, in relation to feed conversion, a linear effect was observed with the increase of cashew bagasse bran levels in the diet. The same effects were also observed in carcass yield, backfat thickness, and fat area. The meat:fat ratio increased linearly with the increase of fiber in the diet. The level of 22.5% of cashew bagasse bran in finishing pig diets is recommended.

RESUMO Objetivou-se avaliar a qualidade dos ovos de poedeiras comerciais armazenados em diferentes temperaturas e períodos de armazenamento. Foram coletados, logo após a postura, 360 ovos de galinhas poedeiras da linhagem Dekalb White. Todos os ovos foram identificados, pesados e distribuídos aleatoriamente às bandejas, sendo 150 armazenados em temperatura ambiente (26,5 ± 0,7°C), 150 ovos acondicionados em refrigeração (7,3 ± 0,5°C) e 60 ovos separados para realizar a avaliação no primeiro dia. O delineamento utilizado foi inteiramente casualizado em esquema fatorial 2×6, sendo duas temperaturas de armazenamento e seis períodos de avaliação da estocagem (zero, seis, 12, 18, 24, e 30 dias), com 30 repetições. As variáveis analisadas foram: pesos dos ovos, pesos absolutos e relativos de albúmen, gema e casca, altura do albúmen, gravidade específica, Unidade Haugh, diâmetro de albúmen, índice de albúmen e de gema. Os valores de pesos absolutos e relativos de ovos, gema e albúmen, altura de albúmen, gravidade específica, Unidade Haugh, diâmetro e índices de albúmen e de gema foram influenciados (P<0,05) pela temperatura e período de armazenamento. Os pesos absolutos de cascas não (P>0,05) foram influenciados pelas diferentes temperaturas, entretanto, as porcentagens de casca foram influenciadas (P<0,05) linearmente pelo tempo de armazenamento dos ovos. Concluiu-se que os ovos armazenados até seis dias após a postura se mantêm em padrão de alta qualidade em temperatura ambiente (26,5°C), e quando armazenados em refrigeração (7,3°C) mantêm padrão de excelente qualidade até os 30 dias.

SUMMARY The study aimed at assessing the quality of commercial laying hen eggs stored under different temperatures and for different storage periods. 360 eggs were collected soon after laying by DeKalb White laying hens. All eggs were identified, weighed, and randomly distributed in trays, being 150 stored at room temperature (26.5 ± 0.7°C), 150 other placed in trays under refrigeration (7.3 ± 0.5°C), and the remaining 60 eggs were set apart so the assessment could be performed on the first day. The trial design was completely randomized 2×11, scheme factorial, with two storage temperatures and six storage periods (zero, six, 12, 18, 24 and 30 days), with 30 repetitions. The assessed variables were egg weights, absolute and relative weights of albumen, yolk and shell, albumen height, specific gravity, Haugh unit, albumen diameter, albumen index and yolk. The values of absolute and relative weights of egg, albumen and yolk, albumen height, specific gravity, Haugh Unit, diameter and indices of albumen and yolk were significantly influenced (P<0.05) by the storage temperature and period. The absolute weight does not of shell (P>0.05) were influenced by different temperatures, however, the percentages of shell were influenced (P<0.05) linearly by storage time of eggs. It can be concluded that the eggs maintain high quality when stored for up to six days after laying, at room temperature, and maintain excellent quality when stored under refrigeration for up to 30 days.
