The buffalo began to be introduced to the country in the early twentieth century, by importing Mediterranean, Murrah and Jafarabadi breeds. Today buffalo population reached 87.711 heads, which are distributed in 20 out of the 23 provinces that conforms the country. The 80% of the population of buffaloes is found in northeastern region, being the provinces of Formosa and Corrientes those with the largest buffalo population. The country has 8 million hectares suitable to withstand a load of 4 million buffaloes. Source

To determine characters prior to slaughtering, slaughtering and commercial cuts of 2 years-old steers, animal carcass from biotypes 3/8 and 5/8 Zebu x Hereford, Hereford, and Zebu were analyzed. Under a complete randomized trial and during three consecutive years, ten steers from each biotype were fed on natural as well as artificial pastures with strategic supplementation. Prior to slaughtering, animals were weight and body condition score was determined (1 to 9 scale). Animals were slaughtered in a type A slaughterhouse. Carcasses were divided into two halves. Classification and typification were performed according to muscular development (shape) and thickness of fat covering muscles (fatness) obtaining weights and carcass yields. After 24 h left carcasses were cut on the 13th rib and then boned. Boneless cuts were classified in different orders, getting individual weights and cut yield from the cold carcass. Differences among body live weight, body condition, and carcass weight were not statistically significant for Zebu crossbreed type. Yield grades were higher and without significance between 5/8 Zebu x Hereford biotype and Zebu type. Young steer categories (carcass less and 118 kg) were the most frequent for all the biotypes. No differences were found in carcass quality, being them homogeneous. Fat levels were 1 and 2. First class cuts were higher in the 5/8 Zebu x Hereford rather than the Hereford biotypes, but there were no differences for cut yields. According to these results, any of the four biotypes may be considered as excellent alternatives to obtain good quality in carcasses destined to the regional market of the north-eastern region of Argentina.

The objectives of the assay were to evaluate the influence of the feeding system (natural grassland vs cultivated pasture) and the approximate age (estimated by number of permanent teeths) on the production of two types of steers (Braford and Brangus), through variables evaluated in vivo previous to the slaughter of animals in four areas of northeastern Argentina. Considering the characteristics of soil, climate, vegetation and productive activity, the farms selected for this trial corresponded to several "homogeneous agroeconomical areas" (HAA). Farms from the Province of Corrientes (General Paz in the HAA I and Santo Tome in the HAA III departments, respectively), Formosa (Patiño in the HAA 8 department) and Chaco (Independencia in the HAA 2 department), were included in this trial. After the fattening period, results obtained on 176 long cycle steers through parameters like individual final weight measured by scale, body condition (BC: scale 1-9), rib eye area (REA) and dorsal fat thickness (DFT) determined by ultrasound technique, were evaluated. The analysis of the variance included the effects type, feeding and "mouthing" (2, 4, 6 and 8 permanent teeths), with an alpha risk of 5%. Differences on steers slaughter weight were not significant between types and feeding systems. Brangus type steers finished the fattening period with a higher BC and Braford type steers with a superior REA and DFT, being in both cases statistically significant in 2-4 years old steers fed on cultivated pasture.
