| In this note the A. A. relate the occurrence of a possible sub-lethal factor, on the Holstein-Friesian herd of Escola Superior de Agricultura "Luiz de Queiroz", Piracicaba. The sire Horto was mated with his own mother, Brisa, and so, were obtained two calves, a male and a female, consecutively. Both the calves presented flexion and deviation of the fore legs. The sire's death has not alloved further observations. The study of these history cases excludes the mother's nutritional deficiency, as the cause of related phenomenon. In the consulted literature, VEIGA and MEAD et al. relate similar cases, although these are observed in other breeds of cattle The A. A. admit that cause of occurrence is a possible sublethal recessive factor, put in evidence by... |

| A test was conducted at Poultry Department of "Luiz de Queiroz" School of Agriculture to prove the effect of green feed on egg production. One hundred Rhode Island Red hens at plain laying period were divided in ten pens. The lot A was constituted of pens 1 to 5 and the lot B of pens 6 to 10. During 16 days the pens 1 to 5 did not receive green feed and the pens 6 to 10 received it with abundance. After and for a period of 30 days the situation was inverted. The analysis were made considering, a) the production of all chickens and b) discarding the chickens with irregular laying. In both cases the results were statistically insignificant, proving that green feed did not improve egg production. |

| The authors repport in this paper, the results of trials by means of which were determined the composition and nutritive value of three grasses, that are cultivated in Piracicaba, in State of São Paulo, Brazil: Capim jaragaá, Hyparrhenia rufa, (Nees.) Stapf. (hay); capim de Rhodes, Chloris gayana, Kunth. (hay), and milho Santa Rosa, Zea mays, L. (silage). The digestion trials were carried out with sheep, following the technique of MEAD and GUILBERT. The chemical analysis of the forages were made by methods usually employed. The results are in the tables I and II, of this paper. |

| The A. A. compare corn silage (Zea mays L.) with sugar cane (Saccharum sinensis Roxb.) in the supplementary feeding of dairy cow. Both the feeds were studied in relation to the following points: composition and nutritive value; influence of milk production, milk fat, milk acidity and body weight; cost of production. Both corn silage and sugar cane were analysed by ordinary methods, and their digestibility was determined by means of digestibility coefficients; their composition and nutritive value are, practically, equivalent, but silage showed slight superiority. The feeding experiment was carried out with two groups of six Holstein Friesian cows each, of the Escola Superior de Agricultura "Luiz de Queiroz" herd. Both groups were fed with the same basic... |

| This paper deals with the estimation of milk production by means of weekly, biweekly, bimonthly observations and also by method known as 6-5-8, where one observation is taken at the 6th week of lactation, another at 5th month and a third one at the 8th month. The data studied were obtained from 72 lactations of the Holstein Friesian breed of the "Escola Superior de Agricultura "Luiz de Queiroz" (Piracicaba), S. Paulo, Brazil), being 6 calvings on each month of year and also 12 first calvings, 12 second calvings, and so on, up to the sixth. The authors criticize the use of "maximum error" to be found in papers dealing with this subject, and also the use of mean deviation. The former is completely supersed and unadvisable and latter, although equivalent, to... |

| The A. A., in this paper, relate the observations on a bovine herd affected by papilloma or common warts; it was treated with the specific medicament "Figueirina", made in the "Laboratório de Biologia Veterinária", of Matias Barbosa, Minas Gerais, Brazil. In twenty-six affected animals, twenty showed complete cure after the treatment, three of them improved, and the other three didn't show any satisfactory results. Among the cured animals, twelve were young and eight were adult. The uncured animals were all adult. In most cases, the warts disappeared rapidly with two applications. In those animals that had resisted four applications, the warts didn't disappear, even with greater dosis. "Figueirina" showed more efficience in the treatment of young animals. |

| The authors repport in this paper, the results of trials by means of which were determined the composition and nutritive value of Capim Jaraguá, Hyparrhenia rufa (Nees) Stop/, cultivated in Piracicaba, in State of São Paulo, Brazil. The experiments were made with hay, silage and also the grass at three different stages: before, during and after blooming. The digestion trials were carried out with sheep, following the technique of MEAD and GUILBERT. The chemical analysis of the forages were made by methods usually employd. The results are in the table XXIV e XXV of this paper. |
