| Abstract:The objective of this work was to define the traits that should be included as breeding objectives for Nellore cattle, according to simulations with a bio-economic model for rearing systems. The economic values (EVs) of the traits were calculated as the differences between the profits due to an increased performance of 1% in each trait, with the others traits remaining constant. To determine the impact of each selection on the revenue system, two scenarios were simulated based on the traits being selected. In the first scenario, the adopted selection criteria were: weaning weight (WW), weaning rate (WR), yearling weight (YW), and mature cow weight (MCW). In the second scenario, the cumulative productivity (CP) of dams was used as an indirect... |

| A pecuária brasileira de corte e de leite produz certa proporção de bezerros problemáticos, de baixo valor, que poderiam ter melhor aproveitamento econômico. Uma das possibilidades e a produção do vitelão, bezerro oriundo da pecuária de leite ou de corte, que ao ser desmamado recebe alimentação sólida e abatido com ate doze meses de idade. Para identificar as potencialidades de aceitação e a demanda desse produto, realizou-se um estudo exploratório em Campo Grande, MS, utilizando uma amostra não probabilística composta de clientes da casa de carnes "Arildo Carnes Especiais". A carne de vitelão foi oferecida a consumidores e em seguida aplicou-se um questionário contendo perguntas sobre pre -conhecimento, avaliação e pre-disposicao para o consumo desta.... |

| The livestock sector must be redesigned in order to achieve food security sustainably. Several authors have argued that organic farming may contribute positively in this sense. However, the externalities of the organic livestock systems are influenced by several factors. Due to this, the aim of this paper is to shed light on the needs and perspective of the organic beef cattle farms located in the 'dehesa' ecosystem (SW Spain). For this purpose, we created the 'Feasibility of Success Index' (FSI) by using indicators that took into account the context of the extensive livestock systems located in the Mediterranean basin. Two groups of organic farms were analyzed: farms that sold calves at weaning age a conventional ones (Organic); farms that fattened and... |

| The present field study documents substantial changes in the soil microbial community (SMC) and organic matter (SOM) in an upland pasture soil resulting from 10 years of “cattle outdoor over-wintering practice”. Soils from a long-term investigated pasture area were compared under three different levels of cattle impact (SI – severe, MI – moderate, NI – no impact). Extended polar lipids analysis (PLA) confirmed a qualitatively new microbial community profile and a several-fold increase of the microbial biomass in the impacted soils (SI) compared to the control NI soil. The new SMC was derived from cattle intestine microorganisms, typical by increased content of archaeal phospholipid ether lipids and by new fatty acids indicative for bacterial and fungal... |

| As part of the National Animal Health Monitoring System (NAHMS ), USDA:APHIS:Veterinary Services conducted a national study of beef production, the Beef Cow/Calf Health and Productivity Audit (CHAPA). This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. Data for Part 1: Beef Cow/Calf Herd Management Practices in the United States, were collected from beef producers September 29 through October 9, 1992. The National Agricultural Statistics Service (NASS) collaborated with VS to select a statistically designed producer sample that represented all U.S. cow/calf operations in the 48 continental United States. Eighty-one percent of operations had commercial cattle... |

This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. Data for Part III: Beef Cow/Calf Health & Health Management were collected by federal and state veterinary officers (VMO's) in 18 of the largest cow/calf producing states between January 4 and February 28, 1993. These 18 states represented 70 percent of the U.S. beef cow inventory. Participating producers had five or more beef cows or beef replacement heifers and fifty percent or more of their 1992 calf crop... |

| The objective was to characterize cattle slaughtered from the region of Lavras - MG. In the public abattoir 720 bovines were identified and slaughtered from September 20th through November 20th of 2004. Variables such as: genetic origin, live weight, body condition, age, and sex were studied. At arrival, animals were weighed and classified according to their genetic origin. Before slaughter, their body condition (BC) was determined on a 1 - 9 scale. Reproductive status was observed during scratch and evisceration: castrated male, MC; intact male, MI; pregnant female, FG; and Non-pregnant female, FNG. Age was determined by the count of the permanent incisive teeth (p.i.t.). Most animals slaughtered during the survey were male, with predominance of the... |

| Bluetongue virus (BTV) antibodies were analysed in 27 Swiss calves born in 2016 at the age of 16–19 days using competitive enzyme-linked-immunosorbent-assay (cELISA) and virus neutralization test (VNT) (animal trial permission number: 75684). Obligatory documentation proved that 15 of 27 dams were BTV-8 vaccinated once or three times in 2008–2010. The offsprings of the non-vaccinated dams were seronegative. Two of three calves and 11 of 12 calves descending from dams who had been vaccinated one or three times, respectively, had BTV specific serum antibodies. As Switzerland is considered BTV-free from 2010 to 2016, it is likely that BTV-8 antibodies were transferred via colostrum. Furthermore, we confirmed neutralizing cross-reactivity of BTV-8 with BTV-4... |

| Il existe peu d’informations concernant la gestion des veaux en montagne. Dans cette zone d’exploitation agricole, l’élevage occupe une place importante, marquée par l’économie alpestre. Aux fins de l’étude, onze chefs d’exploitations laitières et d’exploitations d’engraissement du canton des Grisons ont été interrogés sur la santé des veaux. Leurs réponses ont été analysées à la lumière de la Theory of Planned Behavior ou TPB (théorie du comportement planifié) développée par Ajzen. Les personnes interrogées exercent le commerce des veaux principalement à l’échelle régionale. En raison de l’estivage, le commerce des veaux est saisonnier. Certains décrivent une coopération étroite entre les exploitations laitières et les exploitations d’engraissement. Cela... |
