| Fifteen lambs were fed diet with normal (0.11%) or deficient levels of sodium ( 0.035%), respectively, for five weeks on each diet. At the end of each period saliva was collected by three different methods: swabbing with a 5 x 5 x 1.25cm synthetic sponge, aspiration with a 15cm long plastic tube connected to a 20ml syringe and sucking with a 4mm x 45cm long plastic tube through a water-jet aspirator pump or an eletric motor pump. The volume of saliva collected/min and the salivary sodium: potassium ratio were analysed. Larger volume of saliva was obtained with the developed sucking apparatus than with the sponge or the syringe. There was no influence of the method of saliva collection on the values of salivary Na:K ratio in both periods. Nevertheless, the... |

| The present study aimed to report the occurrence as well as the clinical, laboratorial, pathological and mycological findings of three outbreaks of rhinocerebral and rhinopharyngeal conidiobolomycosis in sheep from Rio Grande do Norte state, Brazil. A total of six sheep with clinical signs of conidiobolomycosis were evaluated, and information on history was obtained from ranchers. Clinical signs included depression, progressive emaciation, sero-sanguinolent nasal discharge, tachycardia, dyspnea, miosis and unilateral exophthalmia with increased ocular globe volume, corneal ulceration and nervous system signs. The main hematological alteration was neutrophilia. Serum biochemical evaluation revealed increased values for AST, GGT, creatinine, urea, and... |

| The objective was to evaluate if supplemental LH given at the end of FSH treatment would synchronize the time of ovulation and increase the ovulation rate and embryo yield in Santa Ines ewes. Twenty superovulatory (SOV) programs were accomplished in cross-over design (60d interval). On D0, a CIDR device was inserted, and the device was replaced with a new one 7 days later, when 37.5µg of d-cloprostenol was administered. On D12, we started the SOV treatment, administering 256mg of pFSH 8 times, 12h apart. On D14, the CIDR was removed, and 200IU of eCG and 37.5µg of d-cloprostenol were administered. On D15, the ewes were allocated into one of two groups, a Control group (n=10) that received no supplemental LH and a LH group (n=10) treated with 7.5mg of LH... |

| ABSTRACT: Leptospirosis is a zoonosis that is widely distributed in tropical countries. This infection is also associated with reproductive losses in livestock, which has a significant economic impact. The objective of this study is to investigate the seroprevalence and risk factors associated with leptospiral infection in commercial sheep flocks from the northwestern mesoregion of Rio Grande do Sul. Serum samples were analyzed in 319 sheep using the Microscopic Agglutination Test (MAT). At the time of sampling, an individual and herd questionnaire was carried out to investigate the risk factors. On an individual level, positive reactions were observed in 5.6% (18/319) of the studied sera, with Sejroe being the most prevalent serogroup. Animals >3 years... |

| ABSTRACT: This study aimed to evaluate the effects of replacing oat hay with coffee husk in the diet of lambs on the intake and apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), non-fiber carbohydrate (NFC), neutral detergent fiber (NDF), and acid detergent fiber (ADF). The experimental design was 4×4 Latin square with four levels of replacement of oat hay with coffee husk (0, 7.5, 15, and 22.5%) with four individually housed Texel sheep. Intake and apparent digestibility coefficients were measured at four periods of 12 days. All orts and feces were collected, weighed, homogenized, and sampled. The use of coffee husk at up to 22.5% of the total DM in the diet of lambs improved the intake of nutrients.... |

| ABSTRACT: Amorimiapubiflora (Malpighiaceae), which contains sodium monofluoroacetate (MFA) is the main cause of "sudden death" in cattle in the Brazilian state of Mato Grosso. This research investigated the induction of resistance to the poisoning in sheep by the continuous administration of non-toxic doses of the plant and also the possibility to transfer this resistance to other sheep by the transfaunation of ruminal fluid. For this a group of four sheep (G1) received daily doses of 0.5g kg-1 for 20 days and after an interval of 15 days were challenged with three daily doses of 1g kg-1 for 3 days. Also the transfer of resistance to A. pubiflora poisoning was evaluated by transfaunation of rumen fluid (100ml for 10 days) from G1 sheep to five sheep (G2),... |

| The genetic variability of 22 protein loci was investigated in two sheep flocks: 22 females Romney Marsh and 124 animals derived from crossbreeding between Romney Marsh and Merino Booroola, reared by the Brazilian Agricultural Research Corporation (Empresa Brasileira de Pesquisa Agropecuária -EMBRAPA, Bagé, RS, Brazil). Eight loci were polymorphic; the others showed no variation. The usefulness of the eight plymorphic systems (Cat, DIA I, EP-1, EsA, HbB, ME, Tf, and X Prot.) in parentage tests was analyzed. The probability to find two random identical animals in each breed was estimated as 1:1000. The efficiency of these proteins for exclusion of one of two possible sires in parentage tests was about 77% both for Romney Marsh and Romney/ Booroola flocks.... |

| The use of alternative feedstuffs in animal diet, such as residues derived from the biodiesel production aims to increase productivity and reduce costs in animal production. Them aim of this study was to evaluate the substitution effect of 0, 22, 44 and 64% of soybean meal protein by Crambe cake (Crambe abyssinica Hochst) protein in lamb diet. In the in vivo experiment, 20 lambs were used and evaluated the apparent digestibility, nitrogen balance and voluntary DM intake. The replacement of the protein resulted in a linear decrease in apparent digestibility coefficient (ADC) of dry matter (DM), organic matter (OM), ether extract (EE), gross energy (GE), acid detergent fiber (ADF), neutral detergent fiber (NDF), cellulose (CEL) and the percentage of total... |

| Sheep farming is designated to economic exploitation, and dry matter intake is the most important factor that influences the performance of animal, thus seeking alternative foods. This study aimed to evaluate the effects of inclusion levels of cassava peel on intake, digestibility and performance of feedlot lambs. We used 32 crossbred lambs Santa Inês uncastrated, mean body weight of 21 ± 1.5 kg. Treatments were arranged in a randomized design to animals, with inclusion levels of cassava peel (0, 10, 20, 30%) in the diet dry matter and forage cassava leaf hay. During 70 days, there have been weighing the food provided, leftovers, and animals, and feces collection. The intake of dry matter (DMI), organic matter (OMI), crude protein (CPI), ether extract... |

| The experiment was carried out in the sheep division of Universidade Federal de Lavras, aiming to evaluate the effect of different concentrate : voluminous ratio on the performance of Santa Inês lamb after wean. 40 lambs, male uncastrated, were used and fed with four different diets: diet A (100% concentrate), diet B (75:25 concentrate : voluminous) , diet C (50:50 concentrate : voluminous) , diet D (25:75 concentrate : voluminous). The experimental diets were isoproteic, differing only on its levels of concentrate : voluminous and balanced to meet the nutritional demands according to the recommendation of the Agricultural Research Council (1980). The experimental period was not pre-established, because it corresponded to the necessary period for the last... |
