A stochastic input distance function is estimated to analyse the efficiency with which physical characteristics of individual lot-fed beef cattle in Australia are combined with conventional inputs to produce a final product possessing defined quality attributes. High mean technical efficiency estimates are reported for all animals and by breed. All partial output elasticities with respect to in...
Consumers are very concerned in "Protected Designation of Origin" (PDO) products, namely meat, since they associate these products to quality and healthy foods. Thus, it is necessary to implement analytical methodologies that could assure consumers about the products they purchase. Since this kind of meat is usually sold with no information concerning cattle sex, age and slaughter season, these...
Beef palatability traits include incidence of connective tissue, juiciness, and flavor but what I am going to focus on in this presentation are Warner-Bratzler shear values and taste panel tenderness. These latter two characteristics are those about which we hear the most discussion regarding problems in consumer trials. Warner-Bratzler shear is an objective method of measuring meat tenderness....
Background: Toxoplasmosis, caused by Toxoplasma gondii, is a common parasitic disease, affecting almost one-third of the world’s population. It is transmitted by ingestion of food or water contaminated with oocysts excreted by cats and the consumption of raw or undercooked meat from ruminants. This study aimed at molecular characterization of T. gondii in native cattle from West of Tehran, Iran...
godina XVII (2015.) ■ siječanj-veljača ■ broj 1 ■ MESO ■ 73 INTRODUCTION Meat production makes a signicant part of the total value of agricultural production in many countries, and given it is labour-intensive, meat production contributes to the increase in employment both on farms and in entire rural areas (Ažderski et al. 2011). Cattle rearing plays an important role in landscape conservatio...
To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes hav...
Yak are crossed with Bos taurus and Bos indicus cattle, including common local cattle breeds (via natural service) and via artificial insemination of frozen-thawed semen from improved breeds (e.g. Holstein Friesian). Female hybrids reach puberty and mate a year earlier than pure yaks. Nonpregnant F1 females usually have several estrus cycles in the same season and will generally calve every yea...
Fourteen Hereford steers were used to compare carcass traits, meat quality, and fatty acid composition of beef from cattle grazing tall fescue infected with either wild-type (E+; n = 6) or novel, nil ergot alkaloid (AR542; n = 8) endophyte for 209 d. Average daily gain, live weight, and HCW were greater (P < 0.05) for AR542 cattle than for E+. No differences in LM color or pH were observed betw...
A serologic screening for Toxoplasma gondii antibodies by IgG indirect fluorescent antibodies test (IgG-IFAT) was carried among 496 swine and 601 cattle serum samples from throughout Costa Rica, to study the possible role of their meat in the transmission of the parasite. The overall prevalence of antibodies was 34.4% in cattle and 43.8% in swine. No significant differences were found in the an...
