Consumo voluntario y rendimiento a la canal en pollos de engorde con residuos pos cosecha de Theobroma cacao L.
(2016) Silva Bastidas, Alberto Hernán; Barros Rodríguez, Marcos Antonio
The objective of this investigation was guided to the determination of the voluntary consumption and yield to the channel in chickens of it puts on weight fed with residual search crop of Theobroma cocoa L, 300 chickens were used between males and females of 15 days of age, during the course of 45 days he/she is given 3 diets (treatments), 10 repetitions for treatment. The diets consisted on the inclusion of flour of it cracked it of the ear of cocoa (HCMC): for T1 (concentrated commercial or witness), T2 (15% HCMC), T3 (30% HCMC). The variables to consider were: Gain of weight, voluntary Consumption, Yield to the channel. The results regarding the voluntary consumption is not difference (P = 0.0677) was observed, with the highest T3 (136.39g / day) value. While in weight gain difference (P = 0.0001) was observed between treatments, being the highest weight gain T1 and T2 (70.73 and 60.52 g / day) respectively. With regard to the yield to the channel difference is not observed (P=0.0001) among treatments being that of more yield T1 (77.75 kg). It can be concluded that residues post harvest cocoa can be included in the diet of broilers up to 15%, due to its nutritional properties improving productive performance.
Efecto de la ingestión de residuos pos cosecha de Theobroma cacao L. sobre el comportamiento productivo de cerdos en la fase de engorde
(2016) Humberto Arquímides, Silva Bastidas; Barros Rodríguez, Marcos Antonio
The objective of this investigation was to evaluate the effect of the consumption of residual search crop of Theobroma cocoa L. on the productive behavior of pigs in the phase of it puts on weight, 24 pigs of shadowy sex were used with a weight alive average of 50.6±1.35 Kg and an approximate age of 3 months. The pigs were distributed in an aleatory way in individual cages where it was evaluated: the treatments T1 (concentrated commercial or witness), T2 and T3 (15 and 30% of flour of it cracked of ear of cocoa. It was determined: Consumption volunteer, voluntary Consumption for kg/peso vivo0.75, Gain of weight lives, nutritious Conversion. The results with regard to the consumption voluntary kg/day, it presented difference (P=0,0001) among treatments, being T3 that of more value with (3.13 kg/day) of consumed food, contrary to the T1 that consumed (2.54 food kg/day), existing a difference of 0,59 kg/day between both treatments. The voluntary consumption g MS/kg PV0.75 showed difference (P = 0.0001) among treatments, being that of more consumption for T3 with (129.12 g MS/Kg PV0.75), what didn't happen with T1 that presented a consumption of (104.81 g MS/Kg PV0.75). With relationship to the gain of weight difference existed (P = 0.0266) among diets, registering the highest value for T2 (0.885 g/day); and in smaller quantity T1 and T3 (0.782 and 0.732 g/day respectively). While for the nutritious conversion I present difference (P=0.0009) in T1 and T2 (3.30 and 3.35) in front of T3 (4.37) that was the highest. You can conclude that the residuals of search crop of cocoa can be included in the diet of the pigs until 15%, due to their nutritious estates improving the productive behavior.
Rendimiento de biomasa y valoración nutrimental de residuos pos cosecha de cacao (Theobroma cacao L)
(2016) Salazar Moyota, José Alberto; Barros Rodríguez, Marcos Antonio
The objective of this investigation work is guided to the determination of the yield of biomass and valuation nutrimental of residual search crop of cocoa (Theobroma cocoa L), The rehearsal was carried out in the sectors of the Island enclosure the marvels and in the enclosure the Guaiacs canton Marcelino Mari owner county of the Guayas to 17 km of the canton Marcelino Maridueña and to 21 km of the canton Cumandá. In the properties of property of Mr. Enrrique Castle with an extension of the total cultivation of 4 has of variety CCN 51, of 4 years while the property of the seños Luis Salazar with a surface of 1 has of national variety, the cultivation is 7 years of age old they are located to 98 msnm. With a curve of established production and an average of (0.77 and 0.54 tm/año respectively). Yield of biomass was determined of it cracked it of the ear of cocoa (CMC), nutritional Value of biomass (CMC). The results showed difference (P=0.0001) among treatments being that of adult numbers of ears T1 (53.3 kg/ha) with regard to T2 (6.1 kg/ha). While for the weight of the ear, weight of the maguey, and total weight of the biomass was observed difference (P=0,0001) among tratamienros, being observed that the biggest weight in the ear, of the maguey and the total weight of the biomass obtained it T1 (33.8, 2.0 and 35.9 kg/ha) respectively. With relationship to the chemical composition of it cracked it of the ear of cocoa significant difference it was not observed (P=0.0001) among treatments for none of the parameters in study (MS, MB, PC, FDN, FDA and Ashy). You can conclude that the yield of the biomass of the residuals of search crop of cocoa of the variety CCN-51 is the one that contributes the biggest quantity in available residuals, with a nutritional content that can be utilized for the animal feeding, compost elaboration.
