The 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.

Objective to evaluate the in situ digestibility of Indigo (Indigofera suffruticos) and kid (Varronia leucocephala). The experiment was conducted in the academic unit of Serra Talhada-UAST of Universidade Federal Rural de Pernambuco-UFRPE in Ruminants. We used three sheep rumen fistulados, no racial pattern set (SPRD) not castrated. We used the random blocks design in schemes of plots subdivided. The plants selected for hatching were subjected to a drying kiln forced circulation of air at 55° c. After the material was ground in a mill with 3 mm sieve and placed in bags of TNT with dimensions of 5 x 10 x 2 cm having 1.0804 grams of sample of Indigo in each bag and 1.0947 grams of sample from the boy hard in each bag , all in duplicate. The rate of dry matter disappearance of Indigo, took 24 hours to reach the peak of disappearance. In relation to the kid hard, took 96 hours to reach the peak of disappearance, taking 72 hours more than the Indigo. In general the anil obtained higher rate of dry matter disappearance (61.20%) than the kid hard (44.40%). Indigo presented significant difference (P < 0.05) when connected the digestibility of potential and effective (2, 5, and 8%/h) compared to the kid hard. The soluble fraction (a), potentially degradable fraction (b), rate of degradation were greater in anil than the kid hard, as the non-degradable fraction (ND), was increased also in the kid hard on Indigo. Despite Indigo be more degradable than the kid hard, both serve as alternative feed for sheep, contributed satisfactorily to production. It is important more research related to chemical composition and disgestibilidade of these foods as much as others, to strengthen the use of fodder plants of the Caatinga in animal production.
Potencial para criação de lhamas (Lama glama) no semiárido brasileiro
(2022-10-06) Anjos, Marcelo Lopes dos; Souza, Evaristo Jorge Oliveira de; http://lattes.cnpq.br/0510969297765295; http://lattes.cnpq.br/3270165723105659
A criação de lhamas tem crescido e chega ao Brasil com um formato inovador, e voltado para o mercado pet. Este mercado é amplo e diversificado tanto no que se refere à variedade de espécies, quanto de insumos voltado para as mesmas. No Brasil existe um déficit de insumos voltado para a criação de lhamas e os criadores tem utilizado ração comercial formulada com base nas exigências nutricionais de cavalos. Diante disto, objetivou-se verificar o perfil bioquímico sanguíneo e os padrões comportamentais de Lhamas (Lama glama) criadas no semiárido brasileiro e desta forma, estabelecer o melhor nível de proteína bruta para formulação de suplementos. Foram utilizados cinco Lhamas fêmeas, adultas, com peso corporal médio inicial de 115.25 ± 6,90 kg. Os tratamentos apresentaram níveis de proteína bruta (PB) com 14, 18 e 28% e foram ofertados na proporção de 0,4% de acordo com o peso vivo dos animais, duas vezes ao dia, manhã e tarde, e no decorrer dos dias ficaram em pastagens compostas por capim buffel (Cenchrus ciliaris L.). As análises para determinação do perfil bioquímico foram realizadas através de kits comerciais das marcas Bioclin® e analisador semiautomático Bio-2000® . A posição e as atividades das Lhamas na área foram monitoradas por meio de coleiras com Global Positioning System (GPS). Foi utilizado o Change-over design com efeito simples, com três tratamentos (níveis de proteína), cinco animais e três períodos. Os dados foram analisados utilizando o Statistical Analysis System (SAS, versão 9.1). Houve efeito significativo (P<0,05) para os níveis de glicose, ureia, acido úrico, creatinina, colesterol, triglicerídeos e aspartato transaminase (AST). No entanto, os níveis de PB na dieta das Lhamas não alteraram os níveis plasmáticos de proteína total, albumina e alanina Aminotransferase (ALT), (P>0,05). Os diferentes níveis de proteína bruta no suplemento promoveram efeito significativo (P<0,05) no padrão comportamental das Lhamas, onde os animais que receberam o suplemento com 14% de PB apresentaram (P<0,05) maior comprimento cartográfico e maior densidade de Kernel. O suplemento com 18% PB é o mais indicado para Lhamas criadas no semiárido brasileiro, uma vez que, este promoveu o melhor perfil bioquímico sanguíneo sem comprometer os padrões comportamentais.
