“…New animal welfare regulations require innovative raising perspectives to adapt to the demanding world market (DRANSFIELD, 2005;NGAPO et al, 2007aNGAPO et al, , 2007b. Animal welfare, environmental issues, and food security are considered to be the three major challenges that will confront the agriculture business in the coming years (ROLLIN, 1995).…”

The aim of this study was to investigate the effect of intratesticular local anesthesia on weight gain and behavioral and cortisol changes in piglets submitted to castration. Study design was a randomized controlled trial. Twenty-nine male Landrace crossbred piglets aged 3 to 6 days were used. The piglets were randomly divided into two groups: orchiectomy with anesthesia (A, n = 15) and orchiectomy without anesthesia (NOA, n = 14). Piglets in the A and NOA groups were treated with 0.5 mL of intratesticular 2% lidocaine with a vasoconstrictor in each testicle and 0.5 mL of intratesticular 0.9% sodium chloride, respectively. Blood samples were collected from all animals immediately after surgery and at 3 and 6 days postoperatively for measurement of the serum cortisol concentration. Behavior was assessed daily for 6 days by two observers blinded to the treatment. Weight was measured at the same time as cortisol measurement. Analysis of variance followed by the Student-Newman-Keuls test was used to investigate differences in time within and between the two groups. Mean times of six evaluations done for 90 minutes during 6 days of each behavior were compared by Tukey t test. The level of statistical significance was 5%. The serum cortisol concentration was higher immediately after surgery than at 3 and 6 days postoperatively in both groups. Weight gain was greater at 3 and 6 days postoperatively in the A group than in the NOA group. Intratesticular local anesthesia before castration in piglets is technically practical, is in accordance with good welfare practice, and improves short-term weight gain in piglets submitted to castration.

ResumoO objetivo deste estudo foi investigar o efeito da anestesia local intratesticular prévia à castração sobre o ganho de peso, comportamento e alterações no cortisol de leitões. O delineamento experimental adotado foi inteiramente casualisado. Foram utilizados vinte e nove leitões mestiços Landrace -Large White do sexo masculino com idade de 3 a 6 dias. Os leitões foram divididos aleatoriamente em dois grupos: orquiectomia com anestesia (A, n = 15) e orquiectomia sem anestesia (NOA, n = 14). Aos leitões do grupo A foi administrado 0,5 mL de lidocaína 2% intratesticular com vasoconstritor em cada testículo, e no grupo NOA administrou-se 0,5 mL de NaCl 0,9% intra testicular também em cada testículo. Amostras de sangue foram coletadas de todos os animais imediatamente após a cirurgia e posteriormente aos 3 e 6 dias após a cirurgia para a medição da concentração de cortisol sérico. O comportamento foi avaliado diariamente durante 6 dias por dois observadores que desconheciam o tratamento. O peso foi medido ao mesmo tempo que o cortisol sanguíneo. Foi realizada a análise de variância, e o teste Student-NewmanKeuls para contraste entre médias. O tempo médio de seis avaliações realizadas por 90 minutos durante 6 dias para cada comportamento foi comparado pelo teste de Tukey. O nível de significância estatística foi de 5%. A concentra...

“…A wide variety of pig rearing conditions differentiated on claims on dimensions of food production such as eating quality or animal welfare currently exists in Europe (Bonneau and Lebret, 2010). Outdoor or environmentally enriched systems are better perceived than conventional (CON) intensive systems by modern consumers, as CON housing provides a barren environment to animals and prevents them from expressing their natural behaviors (Dransfield et al, 2005;Edwards, 2005). Several studies showed that, in comparison to indoor-reared animals, pigs reared in ALT systems are less aggressive and less active during transport and lairage periods (Geverink et al, 1999;De Jong et al, 2000;Barton Gade, 2008a and2008b;Terlouw et al, 2009).…”

The objective of this study was to evaluate the effects of three alternative (ALT) rearing systems for growing pigs (outdoor: 150 m 2 /pig; straw bedding: 1.30 m 2 /pig; and hut with access to a courtyard: 1.30 m 2 /pig) compared with a conventional system (fully slatted floor: 0.65 m 2 /pig, considered as control), on pre-slaughter stress indicators in relation with meat quality. To that end, the number of skin lesions on whole carcasses, as well as blood creatine kinase (CK) activity and urine levels in cortisol and catecholamines (adrenaline and noradrenaline) were determined at slaughter. Glycolytic potential (GP) and ultimate pH of the semimembranosus muscle were also measured. The global correlation network calculated between all these parameters shows that the indicators of pre-slaughter muscle activity (plasma CK) and/or stress indicators (e.g. adrenaline) are negatively (r 5 20.26, P , 0.01; r 5 20.29, P , 0.05, respectively) correlated with muscle GP and positively (r 5 0.17, P , 0.05; r 5 0.44, P , 0.001, respectively) with meat ultimate pH. Although some traits measured were sensitive to the degree of pre-slaughter mixing, they differed across rearing systems. The differences were most pronounced for the comparison of outdoors v. slatted floor. The lower levels of plasma CK and urinary catecholamines, and the lower number of carcass skin lesions of pigs reared outdoors, were related to a lower meat ultimate pH. Thus, ALT rearing systems influence animal welfare and meat quality, by providing enriched environmental conditions to the animals.

“…This trend is primarily driven by the lower cost of production (Thornton, 1988), and growing consumer interest in alternatively produced pork. In addition, some consumers are willing to pay more for pork products from pigs grown in outdoor systems (Dransfield et al, 2005). Opportunities for niche marketing accompanied with lower investment costs have caused some producers to switch from standard confinement (CON) systems to semi-outdoor, alternative systems (Honeyman, 1996).…”

The purpose of this study was to compare effects of finishing environment on growth performance, pork quality and lipid composition of pork. Environments compared were standard confinement (CON) and deep-bedded semi-outdoor systems. The deep-bedded method employed in the current study was the use of hoop structures. Hoops are large, tent-like shelters with cornstalks or straw for bedding. Gilts ranging in weight from 59 to 71 kg were randomly assigned to treatments of Hoop (n 5 50) and CON (n 5 18) environments. Gilts were fed a two-phase dietary sequence, ad libitum for 45 days. Six gilts per treatment were selected for carcass composition and quality evaluation. The experiment was replicated a total of five times. Pigs raised in the Hoop environment gained significantly less and required significantly more feed for growth than pigs raised in the CON environment. Carcasses from CON-finished pigs were significantly fatter at the 10th rib, which lowered carcass percentage fat-free lean(FFL) and they also had greater loin marbling scores compared with carcasses from Hoop-finished pigs (P , 0.05). Significant replication effects were noted on beginning weight, live weight, carcass weight, percentage FFL, backfat, lipid content and adipose firmness. Carcasses from Hoop pigs had lower proportions of palmitic acid (P , 0.05), and higher proportions of oleic and linoleic acid (P , 0.05) in the inner layer of adipose tissue. The proportion of saturated fatty acid was lower, and that of mono-and poly-unsaturated fatty acid was higher in the inner layer of the adipose tissue of Hoop pigs. Variations in fatty acid composition and lipid deposition may have been caused by environmental temperature, since decreases in environmental temperature accompanied compositional variation of the adipose, leading to higher proportions of monounsaturated fatty acid and lower proportions of saturated and polyunsaturated fatty acid in adipose tissue, regardless of treatment. Volatile profile analysis revealed that adipose tissue of Hoop pigs had significantly higher amounts of 3-butanal and heptanal compared with CON pigs, which may be related to the amount of oleic and linoleic acids composing the adipose tissue. These data indicate finishing pigs in hoop structures allows for exposure to fluctuating temperatures, which may influence the growth of pigs, as well as fatty acid composition and firmness of pork products.
