| This study aimed to compare the pregnancy rate using the conventional artificial insemination (AI) or deep intracornual artificial insemination (DIAI), with low number of spermatozoa (4.0 million sperm) in 270 Nelore cows. The animals were divided in two groups (G: G1 (135 cows) conventional AI was performed (=semen deposition in the uterine body) and in G2 (135 cows) to DIAI, in ipsilateral horn where the dominant follicle in the ovary had previously been detected, by ultrasound examinations. For both the methods, a single artificial insemination was carried out after visual estrus observation, checked three times a day (morning, afternoon and evening). The pregnancy diagnosis after 45 days was conducted by ultrasound. Results showed a better pregnancy... |

| Introduction: During the last years, concern has increased concerning animal welfare at the farm level. The Associations of Organic Agriculture have elaborated minimum requirements regarding animal welfare. The aim of the study was to compare the welfare status on conventional and organic dairy farms. Conclusions: Concerning sample used (straw based loose housing systems), organic farms on average showed a better welfare status than conventional farms. This has also been demonstrated in other studies (for a review see Hörning, 1998). Mean points achieved in single criteria show deficiencies and therefore potential for improvements. The respective scoring systems seem to be suitable for an on-farm assessment of housing conditions and thus to... |

| The objective of the present study was to compare growth performance of 15 Danish Holstein bull (DHB) calves, 15 Limousine x Danish Holstein crossbred bull (CB) calves and 15 Limousine x Danish Holstein crossbred heifer (CH) calves reared under organic conditions. Spring-born calves were puchased at private farms and arrived at approximately 20 days of age with an average initial body weight of 52.9, 58.5 and 56.1 kg, (SEM 2.6) for DHB, CB and CH, respectively. Calves were kept indoor until weaning at 3 months of age. Calves were gradually introduced to a grass-silage based ration from 3 to 4 months of age. From 4 to 7 months calves were kept on mix grass pasture of ryegrass and white clover. There were significant differences between treatment groups in... |

| El presente trabajo analiza la competitividad comercial de carne de ganado bovino entre los países miembros del Tratado de Libre comercio de América del Norte (TLCAN): México, Canadá y Estados Unidos. La metodología utilizada es mediante indicadores de mercado: participación de mercado, coeficiente de ventaja comparativa revelada (CVCR), tasa de penetración de las importaciones (TPI) y producción expuesta a la competencia (PEC), para ello se utilizan datos del periodo 1997-2008, comparando los valores promedio de 1997 a 1999 contra los valores promedio de 2006 a 2008. Esto permite observar el desarrollo de la competitividad de los 3 socios comerciales a nivel mundial y permite evaluar la competitividad de Canadá y México como principales proveedores de... |

| The complexity of the consumers' behavior has taken the food industry to a new level of dynamism. Therefore, understanding the factors that influence this behavior is decisive for the differentiation of products to niche markets and even to adjust the supply according to consumers' expectancy. This article proposes a conceptual model to identify the factors influencing beef consumption in Brazil. The methodological approach was characterized by a systematic review through a synthesis of research related directly to this topic. Therefore, 76 papers published during the 2000-2014 period, including official documents (statistics), full research papers, abstracts, proceedings, and reports, were selected. Four main factors were related to influences in consumer... |

| A pecuária de corte, apesar de ser um dos segmentos mais importantes da economia do Estado de Mato Grosso do Sul, desde o inicio da década de 90 vem apresentando queda na produtividade geral. Isso esta ocorrendo como conseqüência da redução da produtividade das pastagens, que por sua vez, e resultado de uma serie de fatores que vão desde a escolha da espécie forrageira e o manejo de formação ate a escolha do animal a ser utilizado. Pode-se ressaltar, no entanto, que uma das principais causas e o manejo inadequado das pastagens, em especial, no que diz respeito a pratica generalizada do excesso de lotação. O reflexo primário de tal pratica faz-se sentir na degradação das pastagens com serias conseqüências ambientais, em especial em solos mas arenosos. Do... |

| French suckler farmers need advice on the impact of the conversion to OF. To help them with their decision-making process, we constructed an LP model that optimises the farming system, taking OF constraints and nitrogen balance into account. According to the model, the shift to OF had a greater impact on a mixed crop-livestock farm system than on that of a grassland farm. As a result of the very high cost of organic N fertiliser and the necessity of maintaining the N balance, the shift to OF in the case of the mixed farm resulted in less emphasis on cereal and more emphasis on livestock. For this type of farm, a significant drop in its proportional costs due to extensification was sufficient to maintain the overall gross margin of the holding. For the... |

| Two studies were conducted to evaluate the effects of crude glycerin on feed intake, performance, carcass characteristics, and total digestibility of Nellore bulls. In experiment 1, cattle (n = 30) were fed a control diet without crude glycerin and diets containing 7.5, 15, 22.5, and 30% crude glycerin, for 103 d. Animals were harvested and data of carcass characteristics were collected. In experiment 2, a digestibility trial was performed using indigestible acid detergent fiber (iADF) as internal marker, and five rumen-cannulated steers. Both experiments were conducted as a randomized complete block design and data were analyzed using mixed procedures. In experiment 1 no differences were observed among treatments on dry matter intake, and performance... |
