| The allele frequencies of 10 microsatellite loci previously described for sheep as BM1314, BM6526, OarFCB128, OarHH64, OarCP20, OarHH47, OarFCB48, OarHH35, OarHH72 and BM2508 were estimated for the Uruguayan flocks. A representative sample of 101 individuals composed by the two predominant breeds (76% Corriedale and 24% Australian Merino) was used. The sample did not show a significant tendency towards substructuring, in spite of presenting some significantly different allele frequencies between races. The Corriedale sample presents three loci in which the presence of null alleles is possible. The markers were highly variable, showing between 7 and 15 alleles each. The Polymorphism Information Content Index ranged from 0.63 to 0.87 and the Exclusion... |

| In this study, two successive field trials were conducted during the non-breeding season to investigate various factors affecting on fertility of Suffolk ewes after intrauterine insemination with frozen-thawed semen. In the first year (Experiment 1), three sperm numbers per insemination dose (0.25, 0.5 and 1 million sperm) and five sheep farms were used, and in the second year (Experiment 2), parity, age, body weight, body condition score (BCS) and postpartum days were investigated to compare pregnancy and lambing rates. High pregnancy and lambing rates (70.6 and 70.6%, respectively) were obtained with 0.25 million sperm per dose. There were no significant differences in the pregnancy and lambing rates among the five farms, but there was a tendency for one... |

| O presente trabalho tem como abrangência o estado do Ceará e tem o objetivo de apresentar variáveis que influenciam diretamente ou indiretamente a produção de caprinos e ovinos e, portanto, são importantes para subsidiar tomada de decisão do setor público e do investidor privado no desenvolvimento dessas cadeias. Dessa forma, foram levantadas em diferentes bases as informações relativas a condições naturais, infraestrutura e logística, além de uma análise de custos da exploração caprinos e ovinos, reunindo informações que possam estabelecer pontos fortes e fracos e vantagem comparativa entre os municípios cearenses para a produção dessas espécies, e identificando regiões mais propícias de acordo com as variáveis apresentadas. |

| Diversified production systems are considered important tools for stabilizing the income of smallholder rubber producers in Indonesia. Based on empirical data collected from smallholder rubber producers in the Nucleus Estate Smallholder (NES) development project, estimations were made of the economic feasibility of integrating sheep and selected crops into smallholder rubber production plantations. The dynamic optimization procedure is used as an evaluation technique. This study finds that integration of sheep and crops into smallholder rubber production is economically feasible, particularly for those who utilize family labor for hand harvesting grass and grazing sheep. Integrating sheep alone increases the net present value of future income by 20%.... |

| The purpose of this experiment was to determine the extent to which lamb carcass quality and fat composition could be altered by applying a dry olive cake-based ration instead of a conventional ration or pasture feeding. Three treatments were compared in a completely randomized experiment using 36 single male Suffolk Down lambs with an initial age and live weight of 80 d and 25 kg, respectively. The three treatments were: (a) suckling lambs kept with their mothers on annual Mediterranean grassland (GRAZE); (b) weaned stall-fed lambs on a control ration (CONC); and (c) weaned stall-fed lambs on an olive cake-based ration (CAKE). At the end of the 28-d experimental period, lambs were slaughtered, carcass quality evaluated, and samples of subcutaneous fat... |

| ABSTRACT: Gossypol easily pairs with lysine side chains and enzymes involved in the cellular growth process. The effect of gossypol (a compound present in cotton co-products) in ruminant metabolism and meat quality is not yet clear. This study was undertaken in order to evaluate the effects of cotton co-products in lamb muscle proteome. Twenty-four Santa Inês ram lambs, 5-months old (20.6 ± 1.9 kg), were randomly assigned to four treatments: control (without cottonseed), whole cottonseed, cottonseed meal and high oil cottonseed meal. At 95 days into the experiment, lambs were slaughtered and samples from Longissimus dorsi were collected. Proteins were extracted and analyzed by 2-D electrophoresis. Spots showing a significant effect from the treatment (the... |

| We here identified for the first time the presence of Mycobacterium avium paratuberculosis (MAP) sheep (S) strain in Argentina. IS900 polymerase chain reaction (PCR) was positive. The S strain was compared with MAP cattle (C) strains by using IS1311 PCR-restriction endonuclease analysis (PCR-REA), multiplex PCR and restriction fragment length polymorphism (RFLP) analysis. |

| Clean wool colour (CWC) is an important wool price determinant and has been related to suint characteristics, i.e. sudoriparous and sebaceous gland secretions, such as suint percentage and suint K content. In this work heritability, phenotypic and genetic correlations among wool colour and skin traits were examined. The genetic estimates were assessed by Restricted Maximum Likelihood (REML) procedures using average information algorithm (AIREML) in a Corriedale flock. The traits analysed were wool colour traits (CWC), yellow predictive colour (YPC), and Visual Score; suint traits such as suint percentage and potassium and sodium concentrations in suint, and physiological traits such as potassium and sodium concentrations in the skin, including plasma and... |

| Chilean sheep breeds have a significant founder effect since they descend from very few parents, in some cases population inbreeding has increased and in others there have been significant differentiation processes as compared to their original population. The objective of this study was to estimate the current status of genetic diversity in sheep herds, which comprise the main sheep breeds in Chile, using molecular methods. Animals from four breeding herds were sampled and analyzed. The breeds studied were Corriedale, Suffolk Down, Romney Marsh and Chilota, these are the predominant numerical pure breeds in Chile. From each breed population 40 animals were sampled. Genetic characterization was done using nine microsatellite molecular markers (SSR)... |

| O objetivo desse trabalho e apresentar e discutir, de forma clara e simples, os aspectos que envolvem a inseminação artificial em caprinos e ovinos como prática rotineira de manejo reprodutivo em regiões tropicais. É enfatizado a importância que deve ser dada a nutrição e ao manejo sanitário, bem como, a idade e peso vivo dos animais quando da entrada na reprodução. É apresentado, ainda, os aspectos desde a colheita do sêmen e a sua manipulação, bem como, o emprego da inseminação artificial em nível de Unidade Produtiva, ou seja, da propriedade, inserida num programa de estação de monta. O intervalo entre partos e o tipo de exploração para produção de leite ou carne sao fatores relevantes que repercutem diretamente no sucesso da caprinovinocultura na visão... |

| This study quantified interactions between animal welfare and farm profitability in British extensive sheep farming systems. Qualitative welfare assessment methodology was used to assess welfare from the animal's perspective in 20 commercial extensive sheep farms and to estimate labour demand for welfare, based on the assessed welfare scores using data collected from farm inventories. The estimated labour demand was then used as a coefficient in a linear program based model to establish the gross margin maximising farm management strategy for given farm situations, subject to constraints that reflected current resource limitations including labour supply. Regression analysis showed a significant relationship between the qualitative welfare assessment... |
