Item Degradabilidade ruminal do genótipo de capim-elefante Mott(2019) Sobral, Gilberto de Carvalho; Souza, Evaristo Jorge Oliveira de; http://lattes.cnpq.br/0510969297765295; http://lattes.cnpq.br/7753384548343497The objective of this study was to evaluate the disappearance of dry matter and estimate the potential and effective degradation of elephantgrass Mott genotype along different passage rates (2, 5 and 8% / hour) in sheep kept in the Caatinga area. The experiment was carried out in the UAST / UFRPE Ruminants Sector, with a duration of 20 days, 15 for adaptation and 5 for incubation. Three rumen-fistulated Santa Inês crossbred sheep with an average body weight of approximately 60 ± 2 kg were used. The diet consisted of elephantgrass, cottonseed, maize and mineral salt, with a ratio of 70:30. The material was collected, chopped and pre-dried at 55 ° C for 72 hours. Each set of bags was placed according to the incubation times (0, 2, 4, 6, 12, 24, 48, 72 and 96h) and removed all at once to be washed in running water until the wash water if presented clean and then dried at 55 ° C for 72 hours bags were weighed and the dry matter disappearance determined. To evaluate the disappearance of the dry matter along the incubation times, a randomized complete block design was used in the subdivided plots scheme, so that the treatment effect (Mott genotype) was allocated in the plots and the incubation time in the rumen in the subplots. Data were analyzed by Statistical Analysis Systems (SAS, version 9.1). There was a significant difference (P <0.05) in relation to the disappearance of the dry matter of the Mott elephant genotype grass during the incubation period, reaching its disappearing potential at 72 hours after incubation, after which it stabilized up to 96 hours. In relation to the potential and effective degradability of the dry matter of the Mott elephant grass genotype as a function of the different passage rates (2% / h, 5% / h, 8% / h), there was a significant effect (P <0.05). Mott genotype elephantgrass presented a soluble fraction "a" (28.79%), potentially degradable fraction "b" (47.67%), fraction degradation (b) "c" (5.10%) and non-degradable fraction "ND" (23.54%). Mott elephant grass presents a high proportion of dry matter degradable and is recommended for the production of ruminants.Item Avaliação do comportamento social e alimentar de ovinos jovens, com e sem as matrizes(2019) Freitas, Daniel Carlos da Silva; Ribeiro, Valéria Louro; http://lattes.cnpq.br/2677739330576168; http://lattes.cnpq.br/5185887452546295The objective of this study was to evaluate the social and feeding behavior of young sheep with and without the matrices. Eight male and female animals, three and fiverespectively, with no defined racial pattern (SPRD), with ages ranging from six to seven months of age, were used. Behavioral observations occurred for eight hours daily, from 6 am to 2 pm for three consecutive days, with a five-minute record, using a stopwatch. For the identification of the animals were used yarns for making necklaces with different colors (blue, dark blue, yellow, orange, green, white, silver and pink). The variables related to social behavior, vocalization, integration with the environment, jokes and fights; and feeding, feeding time, rumination time, standing leisure, lying leisure and water consumption were recorded in an etogram. During the days of observation, two observers write the records of the behavioral variables and the third (fixed during the days of observations), to identify and record the other social and food activities. It is concluded that the separation of young sheep from their matrices can modify the social and feeding behaviors of the animals. Among the results obtained the social variables as interaction with the environment and vocalization; (P> 0.0001), between the treatments (animals raised jointly (mother and offspring) and offspring separated from their mothers and put in an attached picket), probably due to climatic conditions and the environment, separation of the offspring from their mothers, formation of a new social organization, etc. However, some variables such as total rumination time and total leisure time, there was no significant difference between the treatments, probably due to the preference on the side of lying down or the position of limbs and trunks, selection capacity.
