Item Comportamiento productivo de ovinos alimentados con dietas a base de fruta de pan (Artocarpus altilis)(2017) Silva Bastidas, Arsenio Oliveros; Barros Rodríguez, MarcosThe objective of this research was to evaluate the effect of the consumption of diets based on breadfruit (Artacarpus altilis) on the productive behavior of sheep. Eighteen male sheep with a mean age of 7 to 8 months and a weight of 22.23 kg were used. A completely randomized design (DCA) was used, with three treatments and six replicates, in addition to an analysis of variance and Tukey's test at 5%, with the statistical package SAS 2009. The treatments were T1: 100% alfalfa. (Witness); T2: 80% alfalfa + 20% breadfruit; T3: 60% alfalfa + 40% breadfruit. The variables evaluated were: voluntary nutrient intake (CVMS, CVMO, FVCF and FVCFN), weight gain (GP g / day) and feed conversion (CA), voluntary consumption of dry matter, organic matter and neutral detergent fiber Presented difference P = (0.0001) between treatments being the one of greater consumption T3 (1652.71; 1560.16; 872.63g) respectively. Regarding the consumption of acid detergent fiber, difference P = (0.0001) between treatments was observed, with the highest T1 value (585.77g). Regarding the weight gain presented difference P = (0.0001) between treatments obtaining the highest weight gain T3 (218.88 g / day). The feed conversion presented difference P = (0.0001) obtaining the smallest result T3 (7.55). Based on the results obtained, it is concluded that sheep fed diets containing 40% of breadfruit inclusions constitute an alternative food resource, being able to improve the productive parameters obtaining a good productive response, possibly due to the content of non-structural carbohydrates present In T3Item Efecto del consumo de dietas a base de fruta de pan (Artocarpus altilis) sobre la digestibilidad de los nutrientes en ovinos(2017) Ruilova Ruilova, Ruth Araceli; Barros Rodríguez, MarcosThe objective of the present research was to evaluate the effect of the consumption of diets based on breadfruit (Artacarpus altilis) on the digestibility of nutrients in sheep. For which 12 male sheep with an average age of 7 to 8 months and an average weight of 23.50 kg were used, a completely randomized design (DCA) was used, with three treatments and four replicates, in addition to an analysis of variance and Test of Tukey to 5%, with the statistical package SAS 2000. The treatments were T1: 100% of alfalfa. (Witness); T2: 80% alfalfa + 20% breadfruit; T3: 60% alfalfa + 40% breadfruit. The variables evaluated were: Voluntary intake of nutrients (CVMS, CVMO, CVFDN and CVFNA), Apparent nutrient digestibility (DMS, DMO, DFDN, DFDA) Being the highest value T3 and T2 (1651.29 and 1594.21 respectively). The voluntary consumption of organic matter and neutral detergent fiber presented differences (P = 0.0002 and 0.0001) between treatments, with the highest consumption T3 (1558.82; 871.88) and T2 (1496.96; 835.37) respectively. While for the voluntary consumption of acid detergent fiber shows differences (P = 0.0001) being its greater consumption T1 and T2 (583.01 and 582.26) respectively. Regarding the apparent digestibility of dry matter and neutral detergent fiber, differences (P = 0.0001) were observed between treatments, with the highest T3 digestibility (48.23 and 43.34), respectively. The digestibility of acid detergent fiber did not show a difference between treatments (P = 0.2208), based on the above results, and the differences between the treatments (P = 0.0001) and the highest digestibility T3 and T2 (55.58 and 53.91 respectively) It can be concluded that the incorporation of breadfruit in sheep diets can improve the digestibility of nutrients, possibly due to the non-structural carbohydrate content present in T3, which can improve the ruminal environment.
