“…The differences between Lithuanian pig breeds in the proportions of carcass primal cuts were lower than those between autochthonous Italian Casertana and Large White, and commercial Duroc pigs [39]. Low feeding regimen for Mexican hairless pigs together with their age increase at slaughter increased the yield of all primal cuts [52]. Feeding restriction at the finishing phase also tended to increase (p = 0.061) the proportion of belly.…”

The diversity of breeds is an important factor influencing carcass and meat quality traits that are also associated with other different effects. The objective of this study was to investigate the effects of breed, gender, and feeding level in the finishing phase on the carcass and meat quality of Lithuanian White and Lithuanian Indigenous Wattle pigs reared indoors. After 60 kg weight, half of the animals from both breeds were fed a restricted diet of approximately 82% of average ad libitum feeding intake, and the other half of pigs were further fed ad libitum to the end of the experiment. Feed restriction during the finishing phase decreased daily gain and weight of pigs at slaughter, and backfat thickness at the tenth rib (p ˂ 0.001, p ˂ 0.01, and p ˂ 0.05, respectively). Lithuanian White pigs demonstrated higher (p ˂ 0.001) growth rate, live body weight at slaughter and carcass weight, and had a higher (p ˂ 0.01) length of carcass and loin area and lower (p ˂ 0.05) backfat thickness at the last rib and at two points at the lumbar area compared with Lithuanian Indigenous Wattle pigs. The semimembranosus muscle of Lithuanian White pigs had relatively (8.1%) lower (p ˂ 0.001) proportions of saturated and 41.2% higher (p ˂ 0.001) proportions of polyunsaturated fatty acids compared with the pigs of the Lithuanian Indigenous Wattle breed, whereas in the longissimus muscle and subcutaneous tissue, the breed only affected the n-6/n-3 ratio (p ˂ 0.01 and p ˂ 0.001, respectively). Gender showed an effect on saturated fatty acids in all the studied tissues, however, the effects on polyunsaturated fatty acids were found in the semimembranosus muscle and subcutaneous tissue (p ˂ 0.05 and p ˂ 0.001) and the effects on monounsaturated fatty acids was found only in the semimembranosus muscle (p ˂ 0.01). These differences in the fatty acid composition of the semimembranosus muscle and subcutaneous tissue of females exhibited more favorable lipid quality indices compared with castrated males (p ˂ 0.001). The semimembranosus muscle of Lithuanian White pigs also showed more favorable lipid quality indices in relation to healthy nutrition compared with Lithuanian Indigenous Wattle pigs (p ˂ 0.001). This study is one of the steps toward the development and utilization of endangered breeds. The obtained information can be used to increase choice in pork production and consumption, and provides new insights for research into the conservation of local breeds.

“…Future studies should be conducted to evaluate a more subtle restrictive energy feeding to achieve the desired goals. Previous research (Aharoni et al, 1995;Luccia et al, 2003;Rodríguez-González et al, 2016) has demonstrated that feeding higher energy rations increased DM, protein, and lipids compared to feeding a lower energy ration. The concentration of intramuscular fat has been shown to be important for meat palatability and flavor (Fisher et al, 2000;Hopkins et al, 2006).…”

Energy is a key factor regulated by the neuroendocrine system. The objective of this study was to compare growth performance, serum biochemical indices, carcass traits, meat quality, and nutrient composition of lambs fed restricted metabolizable energy (ME) intakes to mimic the seasonal changes of the natural grasslands of northwest China. Nineteen male Dorper × Small Tailed Han lambs were assigned to treatments, control (CON) fed at 1.0 MJ/W 0.75 × d −1 throughout the 180 d study, and restricted ME (RES) fed by sequentially restricting ME every 30 d (0.56, 0.84, 1.0, 0.84, 0.56, and 0.28 MJ/W 0.75 × d −1). Lambs were harvested at the end of the study. Lambs fed the CON diet demonstrated higher (P < 0.05) average daily gain (ADG) compared with RESfed lambs (158.79 and 57.01 g/d, for CON and RES, respectively), although ADG were lower in each period with the last period being a negative ADG for RES-fed lambs resulting in a loss of body weight. Both treatments demonstrated lower ADG in the last 3 study periods compared with the first 2 periods, which may be explained by cold stress (<−3 °C) increasing the lamb's energy requirement. Feeding lambs a restricted ME diet resulted in lower (P < 0.05) blood serum glucose, triglycerides, total protein, calcium, phosphorus, immunoglobulin G, immunoglobulin M, and immunoglobulin A concentrations compared with CON-fed lambs, but both treatments were similar (P > 0.05) for cholesterol and high-density lipoprotein-cholesterol. Feeding lambs a restricted ME diet increased (P < 0.05) meat pH, while reducing the cooked meat rate compared with CON-fed lambs. Thus, the carcass yield, rib eye muscle area, and shear force were lower (P < 0.05) for RES-fed lambs compared with CON-fed lambs. The meat water concentration was higher (P < 0.05), whereas the concentrations of dry matter, crude fat, crude protein, and carbohydrate were lower (P < 0.05) for lambs fed a RES ME diet compared to CONfed lambs. These results demonstrate that sequentially restricting ME intake, as natural grasslands might experience during seasonal forage quality and quantity changes, resulted in a reduction of body weight because lambs were mobilizing body reserves as a source of ME. The reduction in concentrations of key serum nutrients, as well as carcass traits and meat composition, demonstrate the body is responding to the meet the lambs ME requirements, which has implications for both meat quality and the animal's physiological functions.

“…En un trabajo posterior realizado por Rodríguez-González et al (2016) se evaluó la posibilidad de incrementar a 70 kg el peso vivo al sacrifico de los CCP, pero sin incrementar la grasa en la canal, para lo cual, se propuso restringir el consumo de alimento, pero con acceso a forraje fresco para reducir el estrés por hambre. Se evaluaron tres niveles de alimentación: Bajo, 2 veces el requerimiento de energía para mantenimiento; Medio, 3 veces y Alto, 4 veces.…”

“…Se encontró que la restricción de alimento redujo la ganancia diaria de peso (0.300, 0.438 y 0.501 kg, respectivamente), sin embargo, se mejoró significativamente el rendimiento de carne (25.0, 22.8 y 22.0 kg de cortes primarios, respectivamente) y se redujo drásticamente el rendimiento total de grasa en la canal (18.9, 22.8 y 24.5 kg de grasa total, respectivamente). Tal y como lo reportaron Santos-Ricalde y Lean ( 2006), en el trabajo de Rodríguez-González et al (2016) también se incrementó el consumo de forraje, conforme aumento el nivel de restricción de alimento (0.092, 0.121 y 0.307 kg de MS/día para el nivel Alto, Medio y Bajo, respectivamente).…”

“…Se observó, por ejemplo, que los CCP tienen consumos más altos de dietas fibrosas que los cerdos comerciales (1.52 vs 1.20 kg de alimento/día) (Trejo-Lizama, 2005). Una adaptación que ayuda a los CCP a consumir más cantidad de dietas voluminosas es la hipertrofia del estómago, reflejado en el aumento de la curvatura mayor del estómago cuando consumen forrajes (Rodríguez-González et al, 2016). Otra característica interesante, es que pueden consumir mayor cantidad de dietas que contienen ingredientes con factores antinutricionales que los cerdos comerciales.…”

Background. In the Yucatan peninsula there are a large number of floristic resources that can be used in the feeding of monogastric in either intensive or alternative systems that also seek for animal welfare. Objective. To review the information that has been published in scientific journals about the research on monogastric feeding systems in the FMVZ-UADY. Methodology. A compilation was made of the published works on feeding systems of pigs, poultry and rabbits. Publications in scientific journals were considered, where researchers and students of the FMVZ-UADY participated. Main findings. Forty scientific articles were reviewed, of which 10 were about pigs, 26 about poultry and 4 about rabbits. Implications. The information that has been published in recent years has contributed to the knowledge about tropical floristic resources with nutritional potential for monogastric animals, which facilitate their incorporation into poultry, pig and rabbit production systems. Conclusions. The floristic resources available in the region have limitations for their use in monogastric animals due to their fiber content and anti-nutritional factors, however, in the FMVZ-UADY processes, treatments and feed management have been developed that allow their use at acceptable and safe levels, without affecting the productive behavior of the animals.
