O protetor ocular é executado em qualquer material resistente opaco, estéril ou esterelizado, como tela de algodão, película ou filme flexível plástico, ou fibra celulósica prensada, ou ainda uma conjugação desses materiais, com conformação anatômica possibilitando sua aposição superficial às órbitas oculares, adaptando-se, por meio de um recorte em sua porção mediana, à projeção do nariz. O protetor constitui de um tampão posicionado sobre as órbitas oculares, um cordão ou fita de fixação e um passante ou ranhura para a passagem do cordão de fixação.

The aim of this study was to compare four genetic groups of sheep on the carcass and meat quality traits. Thirty-three contemporary and unrelated male lambs, all of single birth were used in the experiment, being thirteen from the Santa Inês (SI) breed, seven from the Brazilian Somali breed (BS), six from the Morada Nova (MN) breed and seven from the ½ Dorper - ½ Morada Nova (F1) crossbreed. The genotypes SI, BS and F1 presented similar performances in relation to hot and cold carcass weights, which values were 10.76±0.53kg and 10.46±0.52kg for SI, 9.20±0.73kg and 8.99±0.71kg for BS, and 9.35±0.73kg and 9.13±0.71kg for F1, respectively. The BS had a better hot carcass yield (47.10±0.88%) and cold carcass yield (46.00±0.87%). Better carcass conformation was observed in SI and F1 (2.73±0.12 and 2.50±0.17, respectively) while the BS presented a better finishing (3.29±0.20). The average for the rib eye area (REA) was 9.94±0.49cm², 8.66±0.67cm², 7.18±0.72cm² and 9.8±0.67cm², and for the carcass compactness index (CCI) it was 0.17±0.01kg/cm, 0.17±0.01kg/cm, 0.11±0.01kg/cm and 0.16±0,01kg/cm, for SI, SB, MN and F1, respectively. There were no significant differences between SI, BS and F1 regarding REA and CCI. Although, in general, the MN presented a relatively lower performance than the other genotypes, this breed had similar carcass yields and fat thickness when compared to SI and F1 and similar conformation and REA in comparison to the BS. Regarding meat quality, no differences were observed between genotypes, except for redness and cooking losses. It is concluded that no one group had a higher or lower performance in all traits analyzed. Moreover, for the management conditions employed in this study, there was evidence of greater specialization in meat production for genotypes SI, BS and F1 when compared to MN, although there are no substantial differences between the four groups regarding meat quality.

Based on the concept that horses have balanced symmetry between its anatomical regions, the aim of this study was to introduce a method of assessing the balance of equines through body proportions. Altogether twelve linear measurements, using metric tape, were measured in 234 horses Quarter Horses for evidence of barrel racing. From these measurements were built nine body proportions, each one given by the ratio of two specific measures, and the effects of sex, weight, age and degree of blood on the balance were evaluated. To check the significance tests we used the F statistic, considering P<0.05. It was found that the linear measurements ML2, ML3 and ML5 were mainly responsible for the disproportionality of the horses evaluated. The effect of sex was significant (P<0.05) for four proportions (R1, R3, R4 and R9) and females were more distant from the concept of balance than males.
