Making Nutritional Blocks Based on Scirpus rigidus (Totorilla) Flour for the Feeding and Fattening of Guinea Pigs

The present study was carried out in the Guano Canton, San José de Chocón community. The objective was to evaluate the productive behavior of guinea pigs when totorilla flour (Scirpus rigidus) is used in their daily feeding. A randomized design was used in a two-factor combinatorial arrangement, for Factor A (flour levels) and Factor B (sex), with four treatments and four repetitions of each versus a control treatment. The treatments were: T0 (0%), T1 (5%), T2 (10%), T3 (15%), and T4 (20%). The evaluation period was 75 days, with an initial weight of 0.41 kg (21 days old). No significant difference was found (p < 0.05) for the final weights (PF), weight gain (GP), total food consumption (CTA), or feed conversion (CA). However, significant differences were found in the weight of the carcass (PC) (p ≤ 0.01); the highest weight was observed in T2 (10% of totorilla flour) with 0.80 kg ± 0.02, and in T0; T3 presented lower results. Significant differences were also found for performance of the carcass (RC) (p ≤ 0.01); the higher values were observed in the T4 and T1 treatments with 77.63% and 74.63%, respectively; a lower value was observed in T3 with 63.82%. In terms of the sex factor variable, male animals presented better results than female ones. 20% totorilla flour corresponded to USD 1.32 profitability. Based on the results, we can conclude that adding totorilla flour to guinea pig feed does not affect their productive behavior and increases the quality of the livestock. For cuyicultural production, the implementation of totorilla flour in guinea pig feed provides a new food alternative and lowers costs.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

Shrimp culture in the floating cage is expected to reduce the utilization of land and its possible negative impact to the environment. The advantages of shrimp farming in the sea include the high dissolved oxygen concentration and the better meat quality. This research aimed to enhance the production performance of shrimp through the utilization of periphyton as a natural feed for shrimp. A completely randomized design with 3 treatments (in triplicates) were applied in this experiment, i.e floating cage without perishel (control), floating cage with PE perishel and PA perishel. Shrimp with body weight of 2.5 ± 0.2 g were stocked at the initial density of 2,000 shrimp in each cage, and maintained for 90 days. No significant difference was observed in the survival amongst treatments. The lowest feed conversion ratio (1.74) and coefficient of variance (3.21) were showed in treatment PA. The highest attachment and abundances of periphyton were found in treatment PA. It was concluded that the addition of perishel inside the floating cage may contribute as natural feed source for the shrimp and thus increase the production performance of shrimp.

The performance and carcass analysis of two popular snail species - Archatina marginata (S) and Achatina achatina (L) commonly reared in West Africa were evaluated from day old to six (6) months of age under the same housing and dietary conditions in a complete randomized design with two (2) treatments, replicated thrice with sixty (60) snails per treatment. The study revealed that at day old treatment 1 (T1) had the higher live weight of 4.03g, while treatment 2 (T2) had 0.31g which showed a statistical significant difference at P<0.05. The shell length and shell width of the hatchlings also showed statistical significant difference (P<0.05) between the two treatments. The mean feed intake (g/day) for T1 was 2.89 and 1.96 for T2. Higher mortality (8.33%) was recorded in T2. T2 was also found to be the better converter of feed to edible meat with feed conversion ratio of 7.26 to 72.3 recorded in T1. The higher dressing out percentage (40.14) was recorded in T1. The result showed that snails generally have slow growth. T1 was found to grow faster than T2 hence it is recommended to the populace because it has higher potential to meet animal protein supply than T2. Research on improvement and nutrition of snails should therefore be encouraged.

ABSTRACT EFFECT OF SUBSTITUTION OF YELLOW CORN WITH BANANA (Musa paradisiaca) PEELS IN THE DIETS ON BROILER PEERFORMANCE. A study has been conducted to determine the effect of substitution of yellow corn with banana (Musa paradisiaca) peels in the diets on broiler performance. The present study used 60 broiler chicks and reared for 5 weeks. A Completely Randomized Design was used as an experimental design with 4 treatments and 5 replications. Treatments were formulated as follow: R0: diet without substitution of banana peels or 0% in the diet; R1: diet with the substitution of 7,5% or 4,28% in the diet; R2: diet with the substitution of 15,0% or 8,55% in the diet; and R3: diet with the substitution of 22,5% or 12,83% in the diet. Variables measured were: daily feed consumption, daily gain, and feed conversion. Research results showed that daily feed consumption, daily gain, and feed conversionratio were all significantly (P < 0,05) affected by treatments. Daily feed consumption at R3 significantly (P < 0,05) lower compared with R0 and R1 treatments, but no differences (P > 0,05) were observed between R2 and R3. No significant (P > 0,05) was observed between R0 and R1, but there was a significant difference (P < 0,05) between R2 and R3 and between R1 and R2. Feed conversion ratio was significantly (P < 0,05) lower for R0 compared with R1, R2 and R3, but no differences (P > 0,05) were observed among R0, R1, and R2 treatments. It can be concluded that banana (Musaparadisiaca) peels meal can be used up to 15% replacing yellow corn or 8,55% in broiler diet. Key words: Broiler chicks, Banana (Musaparadisiaca) peels, Daily feed consumption, Daily gain, feed conversion ratio.

Two experiments were conducted to evaluate diet digestibility, performance, digestive parameters, and blood parameters when an enzyme complex (EC) was used in barley- and rye-based diets with different energy levels. In the digestibility assay (exp. I), 108 seventeen-day-old Cobb male broilers were distributed in a completely randomized design in 2 × 2 × 2 + 1 factorial arrangement with two feeds (barley or rye), two EC levels (0% and 0.02%), and two energy levels [3025 and 3125 kcal apparent metabolizable energy (AME)·kg−1], plus a control treatment. In exp. II, 1080 one-day-old Cobb male broilers were distributed in a completely randomized design in 2 × 2 × 2 + 1 factorial arrangement with two feeds (barley or rye), two EC levels (0% and 0.02%), and two energy levels (2875 and 2975 kcal AME·kg−1). No interactions were observed for any variables (exp. I and II). Enzyme complex improved the apparent metabolizable coefficient of gross energy (P = 0.0432) of diets. The EC provided greater weight gain (P = 0.0003) and better feed conversion (P = 0.0025). Intestinal viscosity at 21 d was reduced (P < 0.0001) with the addition of the EC. The EC improved nutrient digestibility and performance, but the effects of energy reduction on performance could not be overcome.

At the Pastaza Experiment Station of ESPOCH-Ecuador, the effect of two tropical humid grasses Pennisetum sp. (T1) and Pennisetum purpureum (T2), and the plant Tithonia diversifolia (T3), in the feeding of Cavia porcellus (guinea pigs) in the growth phase was evaluated. For this experiment, 210 animals of the improved Peruvian breed were used in three treatments with 70 repetitions. The data obtained was subjected to a completely randomized design, under the Tukey multiple comparison test at a significance level (p ≤ 0.01 and p ≤ 0.05). The fruitful results established that a more efficient feed conversion (5.57) was obtained by providing Tithonia diversifolia (T3), which required fewer quantities to be transformed into bodyweight. However, the best final weights (835.3 g), weight increases (560.97 g), feed consumption (4835.93 g), balanced consumption (2033.66 g), total feed intake (6869.59 g), carcass weights (518.14 g), carcass yield (60.28%), as well as lower mortality were recorded by providing Pennisetum sp. (T1). It also had the lowest cost per kilogram of weight gain with 1.90, as it has a high protein content. The economic analysis determined that it is more profitable to breed guinea pigs in pyramidal burrows when using Pennisetum sp. (T1), since its usefulness (B/C 1.34) was 34 cents for every dollar invested. This is notable because it solves the problems of feeding in the humid tropics, as well as housing them in burrows which reduces the breeding space, thus saving resources that increase profitability.

Para lo cual se utilizó 210 animales de la línea peruano mejorado, mediante tres tratamientos con 70 repeticiones; los datos obtenidos fueron sometidos a un Diseño Completamente al Azar, bajo la prueba de comparación múltiple del estadístico Tukey a un nivel de significancia (p ≤ 0.01 y p ≤ 0.05). Los resultados productivos establecieron que al suministrar el T3, se alcanzó una conversión alimenticia más eficiente (5.57). Pero al proporcionar el T1, se registraron los mejores resultados para: peso final (835.3 g), incrementos de peso (560.97 g), consumo de forraje (4835.93 g) consumo de balanceado (2033.66 g), consumo total de alimento (6869.59 g), pesos a la canal (518.14 g), rendimiento a la canal (60.28%), menor porcentaje de mortalidad; así como también el menor costo por kilogramo de ganancia de peso con 1.90. El análisis económico determinó, que se obtiene mejor rentabilidad al criar cuyes, bajo madrigueras piramidales con la utilización de Pennisetum sp. (T1), ya que su utilidad fue (B/C 1.34); resultados que son aplicables, ya que solucionan los problemas de alimentación y nutrición de la producción de cuyes en el trópico húmedo ecuatoriano; a su vez el alojamiento en madrigueras reduce el espacio de crianza, por lo que al bajar los costos de producción representan un ahorro de recursos que elevan la rentabilidad.
