“…The results of our study indicated that the higher the dietary content of α-linolenic (C18:3n-3) fatty acid, the higher the content of the same fatty acid and other n-3 fatty acids in pork, which agrees with the findings of Rentfrow et al (2003) and Okrouhlá et al (2013). Nuernberg et al (2005) and Václavková and Bečková (2007) reported that supplementation of pig diets with linseed or linseed oil resulted in lower total content of n-6 fatty acids and specifically of arachidonic (C20:4n-6) fatty acid; however, our findings in both experimental groups do not confirm this.…”

“…The experimental diets were formulated based on corn and soybean meal and supplemented with vitamins, minerals and amino acids, following the minimum recommendations suggested by Rostagno et al (2005) for barrows from 100 to 120 kg, with an increase in the levels of metabolizable energy (ME), crude protein (CP) and lysine in diets formulated for gilts.…”

-An experiment was carried out to evaluate the performance, carcass composition, cutting yields and economic viability of 5 or 10 ppm of ractopamine hydrochloride (RAC) in diets for barrows and gilts from 94 to 130 kg.Sixty commercial hybrid pigs within a gender, were individually kept in pens and assigned a randomized experimental block design, in a 3 × 2 factorial arrangement, with three levels of RAC (0; 5 and 10 ppm) and two sexs (barrows and gilts). There were no RAC × sex interactions for all evaluated parameters. There were significant improvements for the groups of RACtreated on final weight, average daily gain (ADG) and feed:gain (F:G). The RAC, independent from the level (5 or 10 ppm), improved the F:G, but did not influence the average feed intake. The gilts had smaller final weight, smaller average feed intake and better F:G. The supplementation with 10 ppm of RAC provided better carcass yield, better longissimus muscle area and better meat percentage. The pigs supplemented with RAC showed better tenderloin yield, better ham weight and better meat percentage of ham. The gilts had better meat percentage, better back fat thickness, bigger belly flexibility and smaller fat thickness of the belly than barrows. On economic viability, the RAC-treated pigs increased the allowance index, gross earnings and net earnings. Compared to the barrows, gilts showed lower total cost, better allowance index and higher net earnings. The supplementation with 5 ppm of RAC was enough to improve performance, carcass composition and cutting yields in the heavy pigs. Furthermore, 5 or 10 ppm of RAC was economically viable and the heavy gilts were more profitable than heavy barrows.Key Words: additive, carcass modifier, lean meat, nutrition, performance Cloridrato de ractopamina em rações formuladas para suínos machos castrados ou para fêmeas na fase dos 94 aos 130 kg RESUMO -Foi realizado um experimento com o objetivo de avaliar o desempenho, a composição de carcaça e a viabilidade econômica do uso de 5 e 10 ppm de cloridrato de ractopamina (RAC) em rações formuladas para suínos machos castrados ou para fêmeas dos 94 aos 130 kg. Utilizaram-se 60 suínos, distribuídos em delineamento de blocos ao acaso, em arranjo fatorial 3 × 2, composto de três níveis de ractopamina e dois sexos. Não houve interação significativa entre a ractopamina e o sexo para as variáveis analisadas. Observou-se, nos animais que receberam ractopamina, maior peso final, ganho de peso médio diário e conversão alimentar. As fêmeas apresentaram menor peso final, consumo médio diário de ração e conversão alimentar. Para rendimento de carcaça, área de olho-de-lombo e rendimento de carne na carcaça, o nível de 10 ppm foi superior ao controle. A ractopamina, independentemente do nível utilizado, reduziu a espessura de toucinho e melhorou o rendimento de filezinho, pernil e carne no pernil. As fêmeas apresentaram maior rendimento de carne na carcaça, menor espessura de toucinho, maior flexibilidade da barriga e menor espessura de toucinho da barriga. As ...

“…In the other sexual categories, ractopamine did not affect feed conversion at 14 days of use. Considering the results obtained with immunologically castrated males, Rikard-Bell et al (2009) observed a positive effect of this additive in feed conversion as early as after 14 days of use, maintaining this result at 31 days. It is important to observe that these authors worked with animals which were lighter (72 kg) compared with those of the present study (92 kg).…”

-Performance and carcass and cut yield of finishing pigs of three sexual categories fed diets with different levels of ractopamine were studied. Forty-eight hybrid animals (initial weight of 92.1±2.4 kg) were distributed in a completely randomised design in 3 × 2 factorial arrangement (three sexual categories: surgically castrated males, two females and immunologically castrated males -with or without 10 ppm of ractopamine), totalling six treatments and eight repetitions with one animal per experimental plot during 28 days. Ractopamine improved weight gain and feed conversion of all sexual categories. The best results were obtained with immunologically castrated males, which, in turn, had lower carcass yield and backfat thickness in the belly. In the absence of ractopamine, depth and loin eye area were higher in females but no differences in these variables were observed between categories when this additive was used. Ractopamine increased the sirloin yield in all sexual categories. There was no difference in bonus index. Ractopamine improves the performance of pigs of 92 to 125 kg.Immunologically castrated males have the best performance responses to ractopamine, but with losses in carcass yield, loin characteristics and backfat thickness of the belly.
