| 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 author studied in this paper effect of chicory (Chicorium intybus L.), kikuyugrass (Pennisetum clandestinum Hoahst) and a variety of Bermuda grass (Cynodon dactilon Pers.) named "Grama seda" as green feeds in growth of White Leghorn chickens (0-8 weeks). Males and females were se-pareted by feathering and development of comb. The results obtained can be summarized as follows : a) - Without separation of sex, the chickens that received green feeds showed better development than that did not receive green suplements. b) - The chicory showed to be something better that kikuyugrass and Bermuda grass, which had a similar effect. c) - The green feeds used had little influence in development of males. d) - The females in the lots suplemented by green feeds... |

| Size and shape in eggs of Rhode Island Red and Light Sussex breeds and in the hibrid Rhode x Sussex were studied. These characters are influenced by quantitative genes. Major and minor diameter were used for estimating size of the eggs and the ratio minor/major diameter for shape indice. It was found, in the material analyzed, that: a) the eggs laid by the sa- me chick are pratically uniform; b) the correlation coeficient between major and minor diameter is weak; c) Rhode Island Red has short eggs than Light Sussex; d) short eggs is dominant on long eggs; e) egg shape is the same in Rhode Island Red and Light Sussex breeds and different in the hibrid, which has rounder eggs than the breeds. |

| At the 2nd. Department of Zootechny of the E. S. A. L. Q., in Piracicaba, between 1953 and 1955 an experiment of sugar cane varieties was carried out, with the objective of discovering varieties to substitute "Taquara" (the variety most widely used) and Co 290 (the most recommended). The former was condemned as being too susceptible to cane smut and the latter showes signs if degeneracy. In the experiment, 8 varieties were used with 3 replications in randomized blocks, in 3 rows each. The cane was crop not in the same period, but when they were at comparable ripeness (70 cm of apparent culm). They were crop twice during the year, with a sharp hoe near the soil. The summary of the results and the statistical analyses are shown in tables 1 to 3, showing the... |

| The author studied the application of chick's feces from battery brooder in the feeding of weaning pigs. He employed a basal ration and substituted 5%, 10% and 15% of that basal ration with similar proportions of chicks' feces. He did not observe statistical significance among the treatments. The results measured in terms of average daily gain and feed conversion indicated that the substitution of 5% to 10% by equal proportions of chicks' feces produced satisfactory results, the 5% proportion being the most advantageous. |

| Bacta-mon, produced by Bacta-mon S. A., São Paulo, Brazil, is recommended as a microbiological, and suggested as a supplement for animal rations. This experiment deals with this product in chicken feeding. Four lots of baby chicken received, during 6 weeks the following treatments: a control ration Rl; a ration R2 containing 10 per cent of wheat standard middlings fermented by Bacta-mon, substituting equal weight of wheat standard middlings of the control ration Rl; two rations R3 and R4, both without meat meal and containing 10 per cent of wheat standard middlings fermented respectively by Bactamon and fresh cow manure, substituting equal weight of wheat standard middlings of the control. The results may be so summarized: (1) On the basis of the weights... |
