In the process of slaughtering chickens, parts of them are discarded because are unfit for human consumption. These wastes should be directed to a destination that does not promote any risk to the environment and above all, according with the laws regulating waste disposal. So, the wastes are transformed into byproducts for utilization in the animal nutrition, poultry and swine feeding, but cannot use for ruminant feed, only non-ruminant feeding. In Brazil, the first scientific studies on the use of by-products of poultry slaughter as a protein source in diets for broiler chickens were started in the 1960's, and these results were used for a long time for food formulation, but the need to improve the herds stimulated the search for improvement in technologies for more accurate diet formulations. The objective of this article is to review some aspects of the physic-chemical composition, energy values and their use in diets for broilers.

The implants are usually used after removal of the eye or its internal content, in order to maintain the orbital volume or, as in medicine, provide also the subsequent placement of ocular prosthesis. Considering prosthetic surgery procedures of high relevance in human and veterinary ophthalmology, this paper seek to review the main types of implants described in national and international literature, as well as describe the main complications when they are used in humans and veterinary patients.

The use of cultivars efficient in nutrient use is essential to increase yield and reduce production costs. The objective of this study was to evaluate absorption and nutrients use efficiency on five potato cultivars. The experiment was conduced in Itaí, São Paulo State, Brazil, in winter cropping season of 2008 on Oxisol. The experimental design was randomized blocks with split-plots and four replications. Plots comprised the five potato cultivars and subplots were established by sampling times, performed at planting and every seven days after emergence. At 97 DAP was calculated the nutrients use efficiency for dry matter production and at 122 DAP were calculated the nutrients use efficiency for fresh tuber and tuber dry matter yield. Mondial and Asterix cultivars showed greater dry matter production, higher fresh tubers yield and nutrients accumulation. Nutrients use efficiency for total dry matter and tubers dry matter, was similar among cultivars, but Ágata was more efficient in nutrients use efficiency for fresh tubers yield.
