The aim of this study was to evaluate the influence of different concentrations of inulin and pectin as fat substitutes on the chemical composition, texture, and sensory acceptance of frankfurter sausages. Six treatments were evaluated to test fat replacement: control (T0); low fat control (T1); low fat with 15% inulin (T2); low fat with 30% inulin (T3); low fat with 7.5% inulin and 7.5% pectin (T4); and low fat with 15% inulin and 15% pectin (T5). The addition of fibers increased the yield (T3 and T5; 98.96%), and the color parameters were slightly reduced (T3). Moisture (61.14%) and ashes (6.96%) of sausages with inulin and pectin were higher (T5), while shear force, hardness, fracturability, gumminess, and chewiness (T3 and T5) were slightly lower than those of the control. The addition of inulin (T2) increased the sensory acceptance of the sausages (5.75). Fat can be replaced with inulin and pectin in frankfurter sausages to produce healthy and functional products.

-The current study was conducted to investigate the effects of Mexican oregano essential oil (MOO) extracts from Lippia berlandieri Schauer (LBS) and Poliomintha longiflora Gray (PLG) on performance, blood profiles, carcass variables, and meat composition of broilers at slaugther. A total of 360 one-day-old Ross broilers were randomly distributed into four dietary treatments with six replicate pens per treatment and 15 birds per pen. The dietary treatments were: a basal diet (control), control + 0.40 g of LBS/kg of feed, control + 0.40 g of PLG/kg, and control + 0.40 g of LBS/kg + 0.40 g of PLG/kg. Results showed that linear, quadratic, and cubic effects of days were significant in the performance variables of broilers. The treatments with LBS and PLG maintained the broiler body weight without increasing feed intake and water intake when compared with the control group. Broilers given LBS+PLG and PLG had increased blood leukocytes, lymphocytes, lowdensity lipoprotein, and hot carcass yields. In meat composition, treatments with PLG and LBS+PLG presented similar breast protein content compared with the control treatment. Supplementation with these two MOO exhibits positive effects on broiler performance, blood profiles, carcass traits, and meat composition. These two MOO may be promising feed supplements as growth promoters and enhancers of meat quality in broiler production.

The addition of rice polishing (RP) and phytase enzyme to poultry diets was tested on 200 1-day-old broilers weighing 42 g. Birds were assigned to a completely random design with a 2 × 2 factorial arrangement with four treatments and five repetitions of ten birds each. The factors evaluated were RP level (0 and 15%) and phytase (0 and 150 g/ton). The trial was divided in two phases of 21 days each (42 days total). In phase 1, no treatment effects were observed (P>0.10) on poultry productive behavior. In the second phase (21 to 42 days) and on the total trial (1 to 42 days), there were no effects of the treatments on weight gain or feed intake (P>0.10). Feed conversion was affected by RP (P<0.01) but not by phytase addition (P>0.10). In conclusion, phytase did not affect broiler production with or without RP. Addition of 15 % RP in poultry diets represents an alternative to reduce feed costs.

The quality of slaughtered turkeys fed a diet supplemented with Mexican oregano (Lippia berlandieri Schauer) oil was investigated. Two treatments were studied. T0: control diet and T1: control diet + 400 mg kg−1 of oregano oil with 60 % carvacrol. Live weight at slaughter was di erent, with T0 weighing 11.0 kg and T1 11.89 kg, while the performance of feathers and drumstick was higher in T0 (4.33 and 3.18 % respectively). Viscera, blood, head, neck and hot and cold carcass yield did not di er between treatments (p > 0.05). Oregano oil at 400 mg kg−1 can be used in the production of turkeys to in uence slaughter quality.

ABSTRACT. The productive performance of pigs fed with solid-state fermented apple pomace (FAP) and an enzymatic complex (ENZ) was evaluated. Twenty-four Landrace x York (38.9 ± 3.6 kg) pigs were fed ad libitum with dierent diet treatments including FAP and ENZ: T0-0 (0 g kgFAP -0 g kgENZ), T0-1 (0 g kgENZ), T50-1 (50 g kgENZ), T100-0 (100 g kgENZ) and T100-1 (100 g kgENZ). Productivity; Feed intake, F:G ratio, Weight gain, return on investment by monetary unit (protability index, PI) and carcass traits; Carcass dressing percent and primary cuts, were evaluated. Data were analyzed according to the randomized complete block design. Productivity and feeding characteristics were not aected by FAP or ENZ (p > 0.05). Hot dressing percent was aected by ENZ (p = 0.0497). T100-0 and T100-0 showed similar (p > 0.05) value to T0-0. Primary cut yield was not negatively aected (p > 0.05). The best PI was obtained with T50-0 in growing phase. FAP improved PI only in growing phase and ENZ combined with FAP showed variant PI. Results showed that FAP may be considered as a suitable option for feeding pigs because it maintains animal productivity.Key words: Pig carcass, solid-state fermented apple, pig performance, pig feeding, primary cuts RESUMEN. El comportamiento productivo de cerdos alimentados con bagazo de manzana fermentado en estado sólido (FAP) y un complejo enzimático (ENZ) fue evaluado. En el experimento se utilizaron 24 cerdos Landrace x York (38.9 ± 3.6 kg), se alimentaron ad libitum con diferentes dietas de tratamiento incluyendo FAP y ENZ; T0-0 (0 g kg ENZ) and T100-1 (100 g kgENZ). Se evaluó la productividad; consumo de alimento, conversión alimenticia, ganancia de peso, índice de rentabilidad (PI) y características de la canal; rendimiento en canal y rendimiento en cortes primarios. Los datos fueron analizados considerando un diseño en bloques completamente al azar. La productividad y las características de alimentación no fueron afectadas por FAP o ENZ (p > 0.05). El rendimiento en canal caliente se afectó por ENZ (p = 0.0497). Los tratamientos T100-0, T50-0 y T0-0 fueron similares (p > 0.05). El rendimiento en cortes primarios no fue afectado negativamente (p > 0.05). El mejor PI fue obtenido para T50-0 en la fase de crecimiento. FAP mejoró el PI únicamente en la fase de crecimiento y la combinación con ENZ mostró un PI variante. Los resultados obtenidos mostraron que FAP puede ser considerado como una opción adecuada para alimentar cerdos y mantener su productividad.Palabras clave: Canal de cerdo, bagazo de manzana, comportamiento del cerdo, cortes primarios
