Efeito do grupo genético e heterose na terminação de vacas de descarte em confinamento

O experimento teve como objetivo avaliar, durante a fase de terminação, o peso, o consumo alimentar, o ganho de peso e a conversão alimentar de vacas de descarte, puras (Charolês-C e Nelore-N) e cruzadas F1 ( ½ CN e ½ NC), bem como medir a heterose resultante. As vacas foram confinadas por um período de 80 dias, sendo todas alimentadas com a mesma dieta, contendo 10% de proteína bruta e uma relação volumoso:concentrado de 65:35. Vacas F1 foram mais pesadas no início (402 vs 362 kg) e no final do confinamento (524 vs 475 kg), sendo a heterose de 11,05 e 10,31%, respectivamente. O ganho de peso médio diário das vacas F1 (1,557 kg) foi similar ao das puras (1,424 kg). O consumo voluntário de matéria seca (CMS) em kg/animal/dia (CMSD) foi 11,26% superior nas vacas F1 em relação às puras. No entanto, ao expressar o CMS por unidade de peso metabólico (CMSM) e por 100 kg de peso vivo (CMSP), a diferença decresceu para 3,25 e 3,57%, respectivamente, e deixou de ser significativa. Vacas C foram mais pesadas e apresentaram maior ganho de peso médio diário que vacas N (1,554 contra 1,294 kg). Vacas ½ CN foram mais pesadas e mais eficientes na transformação de alimentos em ganho de peso que vacas ½ NC.

Morphological aspects of the capybara stomach (Hydrochaeris hydrochaeris): Gross and microscopic structure

The digestive system of the capybara has been investigated because of its coprofagia habits, important for their absorptive activity. These species present differences in terms of gastrointestinal morphological characters when compared with other rodents. Macroscopiclly, the stomach of the capybara is constituted of the following parts: cardiac, pyloric, body, fundic and gastric diverticulum. It presents two curvatures, one big and another small. Externally, the presence of gastric bands (tenias) is observed. With regards to the volumetric view, the gastric capacity varies from 850 to 2010 ml, with an average of 1498.57 ml. So, the stomach of this animal can be classified as a simple stomach, in the format of a curved sack and similar to an inverted letter 'J'. The gastric mucous membrane presents a surface filled by numerous tortuous gastric folds and longitudinally distributed along all its extension. The mucous tunic also possesses recesses located among the successive gastric folds, which were denoted as gastric parts with numerous openings described as gastric pits. In the cardiac part, a glandular epithelium with cardiac glands is noticed containing a lot of parietal and mucous neck cells. The fundic part, body and gastric diverticulum contain proper gastric glands with main, parietal and mucous neck cells. Finally, the pyloric part has pyloric glands with two cellular types, mucous neck and parietal cells.

Desempenho e morfometria duodenal de frangos de corte submetidos a diferentes níveis de energia e programas de alimentação de 42 a 57 dias de idade

This experiment was conducted to evaluate the use of different energy levels and amino acid recommendations on performance, carcass yield and intestinal morphometry of broilers from 42 to 57 days of age. We used 1,600 one-day old male broilers (Cobb 500) in a completely randomized design arranged in a 2x4 factorial scheme with 3,200 and 3,600 kcal ME/kg and four different feed programs. The metabolizable energy levels and the feed programs did not determine significant differences in carcass characteristics for choosing a level of energy or a feed program, thus the energy level and the recommendations of amino acids that determine the highest cost-benefit ratio should prevail. It was observed that 3,600 kcal ME/kg resulted in some improvement on performance and morphometry of the intestinal mucosa, also the fractioning of digestible amino acid requirements during two periods resulted in worse performance and intestinal villi height.

Indícios de subjetividade na fala de uma criança psicótica: um olhar para as hesitações

This study, performed under a linguistic-discoursive prism, aimed to: (1) describe the moments in which occurred hesitations in the utterances of a psychotic child diagnosed with Language Disorder; and (2) determine the extent to which these moments (also) can indicate aspects of a subjectivity trying to emerge in this child. Data were extracted from a speech therapy session with a ten year old female child. Concerning the fi rst goal, from a total of 362 utterances produced by the child, only 74 (20%) had hesitation traces, while 288 (80%) did not. Concerning the second goal, the utterances with hesitation traces occurred in situations of: topic development, especially in the form of complementarity; introduction of new topic; return to the previous topic; refuses to the topic; enunciative incompleteness. The high percentage of utterances without hesitation traces (80%) is explained because they are highly predictable from the context, mostly in situations of ritualized adjacent pairs, oftentimes in situations of immediate specularity. The reduced percentage of utterances with hesitation traces are explained precisely by the fact that, unlike those without traces, in these ones, signs of a subjectivity that tries to emerge and show itself in the discourse production are detected. With the development of this study, we tried to emphasize the view at the hesitations as marks of subjectivity – in other words, evidences of confl icting relationships between the subject and the others that constitute the utter. The concern was also about bringing to the fi eld of Speech Pathology discoursive linguistic refl ections based on data extracted from symptomatic contexts of language.
