Prado,Tayrone F.; França,Aldi F.S.; Meirinhos,Maria Lúcia G.; Peron,Hugo J.M.C.; Ferreira,Reginaldo N.; Oliveira,Leonardo G.; Corrêa,Daniel S..
ABSTRACT The number of sheep flocks in Brazil is increasing. It is known that lambs must be slaughtered when young for producing quality meat. The current study evaluated the inclusion of protected methionine, protected lysine, lysophospholipid and amylolytic enzymes in a diet to lambs and their effects on weight gain and quantitative carcass traits at slaughtering. Eighty non-castrated male crossbred Dorper x Santa Inês lambs, 20.57 ± 4.33 kg live weight, were used. The feedlot lasted 64 days and 60 animals were slaughtered. There were no differences for live weight, daily feed intake, feed conversion and average daily weight gain at the first 28 days of feedlot. From the 28th day lysophospholipid treatment presented the highest live weight....

Avaliação da biodiversidade da Caatinga para controle de nematódeos gastrintestinais de caprinos e ovinos. Infoteca-e
NOGUEIRA, D. M..
Na produção animal, a verminose é um dos fatores limitantes da caprinocultura, sendo considerada a principal doença responsável pelas elevadas perdas econômicas no rebanho. Associado a esse problema está o uso indiscriminado de drogas anti--helmínticas alopáticas que é responsável pela seleção de nematódeos resistentes ou de nematódeos que desenvolvem resistência aos anti-helmínticos. Esta atividade teve como objetivos testar diferentes dosagens em caprinos e/ou ovinos de plantas medicinais já citadas na literatura como detentoras de ação anti-helmíntica e avaliar a eficácia das plantas medicinais da Caatinga conhecidas popularmente como anti-helmínticas, porém ainda não citadas na literatura. Foram utilizados caprinos e ovinos mestiços para cada...

Biometry and ultrasound evaluation of testicles and accessory glands in Santa Ines rams R. Bras. Zootec.
Ribeiro,Mariana da Silva; Quirino,Celia Raquel; Bartholazzi Junior,Aylton; Pacheco,Aline.
ABSTRACT This work aimed to investigate the relationship between echogenicity, testicular biometry, and accessory gland biometry and evaluate the echogenicity pattern of these structures in Santa Ines rams. Fifty-four healthy Santa Ines sheep were classified into three age groups: group 1 - 3 to 5 months (pre-pubertal); group 2 - 7 to 11 months (pubertal); and group 3 - 13 to 28 months (sexually mature). The averages of testicular biometry and bulbourethral gland biometry were different among age groups. The testicular parenchyma was homogeneous with low echogenicity (pre-pubertal group) and medium echogenicity (pubertal and sexually mature groups), suggesting that testicular echogenicity can be a helpful tool to identify the start of puberty. The...

Epidemiological, clinical and diagnostic aspects of sheep conidiobolomycosis in Brazil Ciência Rural
Weiblen,Carla; Pereira,Daniela Isabel Brayer; Dutra,Valéria; Godoy,Isabela de; Nakazato,Luciano; Sangioni,Luís Antonio; Santurio,Janio Morais; Botton,Sônia de Avila.
ABSTRACT: Conidiobolomycosis is an emerging disease caused by fungi of the cosmopolitan genus Conidiobolus . Particular strains of Conidiobolus coronatus, Conidiobolus incongruus and Conidiobolus lamprauges , mainly from tropical or sub-tropical origin, cause the mycosis in humans and animals, domestic or wild. Lesions are usually granulomatous and necrotic in character, presenting two clinical forms: rhinofacial and nasopharyngeal. This review includes the main features of the disease in sheep, with an emphasis on the epidemiology, clinical aspects, and diagnosis of infections caused by Conidiobolus spp. in Brazil. In this country, the disease is endemic in the Northeast and Midwest, affecting predominantly woolless sheep breeds and occasioning death...

Zaros,Lilian Giotto; Coutinho,Luiz Lehmann; Sider,Lúcia Helena; Medeiros,Henrique Rocha de; Neves,Maria Rosalba Moreira das; Benvenuti,Camila Loures; Navarro,Andrine Maria do Carmo; Vieira,Luiz da Silva.
Precise normalization with reference genes is necessary, in order to obtain reliable relative expression data in response to gastrointestinal nematode infection. By using sheep from temperate regions as models, three reference genes, viz., ribosomal protein LO (RPLO), glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and succinate dehydrogenase complex subunit A (SDHA), were investigated in the abomasum, abomasal lymph nodes and small intestine of Brazilian Somalis sheep, either resistant or susceptible to gastrointestinal nematodes infections. Real time PCR was carried out by using SYBR Green I dye, and gene stability was tested by geNorm. RPLO was an ideal reference gene, since its expression was constant across treatments, presented lower variation, and...

Kinematic and spermatic recovery after selection by centrifugation in colloid solutions of ovine cryopreserved semen Arq. Bras. Med. Vet. Zootec.
Bergstein,T.G.; Bicudo,L.C.; Rodello,L.; Weiss,R.R.; Bicudo,S.D..
ABSTRACT Frozen and thawed ovine semen undergo morphological and functional changes that prevent or decrease the efficiency of fertilization. Sperm selection methods seek to improve the quality and viability of the fertilizing materials. Four sperm selection methods were employed, using two silica colloidal solutions coated with silane (silica colloidal-silane) or by polyvinylpyrrolidone (silica colloidal-PVP), and varying the volume of colloidal solution. Sperm kinematic and sperm recovery were evaluated by means of CASA. The protocols using silica colloidal-silane showed higher total motility (TM), progressive motility (PM) and percentage of rapid sperm (%RAP) compared to the methods employing silica colloidal-PVP and to the samples prior to sperm...

Abstract Ovine/caprine ureaplasmas have not yet been assigned a species designation, but they have been classified into nine serotypes. Herein ureaplasmas were searched for in 120 samples of vulvo vaginal mucous from sheep and 98 samples from goats at 17 farms. In addition, semen samples were collected from 11 sheep and 23 goats. The recovered ureaplasma were from sheep and goats from animals without any reproductive disorder symptoms, but not all animals presented positive cultures. In sheep, 17 (68%) cultures of vulvovaginal mucous were positive for ureaplasma and 11 (27%) samples of semen presented positive cultures in animals with clinical signs of orchitis, balanoposthitis or low sperm motility. In goats four ureaplasma isolates were obtained from...
