O Instituto de Zootecnia de Minas Gerais, com a colaboração da Sociedade Rural de Curvelo, M. G., realizou, de 27 de Agosto de 1958 a 6 de Maio de 1959, um estudo preliminar para estabelecer normas mais seguras de escolha de touros zebus. O trabalho iniciado em 1958 em caráter de "ensaio" está sendo continuado em 1959. No primeiro "ensaio" (agosto de 1958 a maio de 1959) foram constituídos 15 lotes de oito animais cada um (4 machos e 4 fêmeas), num total de 120 cabeças, filhos de reprodutores de rebanhos particulares locais. A idade dos animais estava compreendida entre 10 e 14 meses de idade; mas cinco lotes não tinham registro de nascimento e, destes, dois lotes de Nelore eram certamente de idade mais elevada. Foram usados cinco lotes de cada uma das raças Gir, Guzera e Nelore. Os lotes foram formados por sorteio. A duração da prova foi de 252 dias, divididos em períodos de 28 dias. A ração suplementar foi constituida de 10% de farelo de amendoin, 90% de milho desintegrado (toda a espiga), cana picada, além do pasto (seco). A ração foi ministrada apenas na época seca (27-8-1958 a 19-11-1958) em cochos comuns, mas bastante amplos para evitar competição entre os animais. |

Brazil's Atlantic Forest biome is severely degraded and fragmented throughout its range. Developing effective techniques to restore pasture and agriculture back to native vegetation is therefore a priority for legal and conservation purposes. In this study, we evaluate the ability of artificial bird perches to enhance the arrival of new seeds and seedling establishment in a degraded, semi-deciduous seasonal portion of the Atlantic Forest in southern Brazil. Specifically, we assess the influence of previous land use and habitat types on the abundance, species richness and ecological traits of bird-dispersed seeds, as well as on seedling establishment. Eight sampling sites were established, each containing one unit with seed traps and restoration plots under artificial perches and one similar unit without the perches. These sites were located in pasture and agriculture, distributed between riparian and sub-montane areas. Monthly sampling was conducted over two years between December 2005 and November 2007, resulting in the evaluation of 25,755 seeds and 56 endozoochoric seed species. The most abundant species were the pioneers Cecropia pachystachya Trécul and Solanum americanum Mill. Experimental units with perches received significantly more seeds than control units. Moreover, seed arrival was higher in sub-montane areas and on former pasture sites. Species richness followed a similar pattern of higher seed arrival, but there was no effect of vegetation type. Ecological characteristics of seeds were associated with land use type: former pastures received more tree seeds and pioneer species than expected by chance. Seedling establishment was very low in all treatments, with only eight seedlings established in perch plots by the end of the experiment. We conclude that despite artificial perches significantly increasing the arrival of endozoochoric seeds onto degraded lands, seedling establishment is drastically limited in these areas, compromising the efficacy of this technique for restoration purposes.
