The aim of this study was to determine the angle of motion values for hindlimbs in clinically healthy adult Santa Ines sheep using a standard goniometer. Twenty female Santa Ines sheep weighing 32–45 kg (mean30.4, SD=3.7), and aged from three to six years old were used. A standard transparent plastic goniometer was used to measure passive maximum flexion, maximum extension, and range of motion (ROM) of the shoulder, elbow, carpal, hip, stifle, and tarsal joints, in the right and left limbs. The goniometric measurements were done with the sheep awake and in a standing position. The measurements were made in triplicate by two independent investigators. In all evaluated joints there was no significant difference between the means of both sides. No significant difference was observed between measurements performed by the two investigators. The mean (± SD) values of the measurements (degrees) were: 129 ± 4 (ROM) for tarsal joint; 46 ± 4 (flexion), 146 ± 6 (extension), and 100 ± 4 (ROM) for stifle joint; 54 ± 3 (flexion), 143 ± 7 (extension), and 89 ± 5 (ROM) for hip joint. The data obtained is useful to provide objective information of the joints. More studies are necessary using other breeds

The aim of this study was to compare the following four genetic groups of hair sheep: Santa Inês (SI), Morada Nova (MN), Brazilian Somali (BS), and the F1 1/2Dorper x 1/2Morada Nova crossbreed on traits related to growth and parasitic infection. Thirty-three male lambs of the same age and of simple birth, under the same pre-weaning management conditions were used in the experiment. After weaning the animals were housed in a completely randomized design in paddocks made of Panicum maximum cv. Tanzania. Along the course of the research, the performance of the four groups of sheep was observed to be negatively affected by gastrointestinal parasites, but there was a genotype effect to the average daily weight gain (ADWG), where the SI and F1 genotypes presented higher values. The effects of genotype, time and genotype x time interaction were significant in weight and corporal score (CS) measurements. The BS lambs had the highest CS values throughout the experiment despite not presenting greater weight gain when compared to the SI and F1 breeds. There were also significant effects of time and genotype x time interaction for packed cell volume (PCV) and FAMACHA© score (FAM) and only the time effect was significant in the total number of eggs per gram (EPG) and total plasma protein (TPP). The MN lambs showed higher PCV values and unlike the other groups, presented a FAMACHA© score below 3 and PCV above 23% even having a higher EPG tendency, especially in the initial phase, indicating a possible higher resilience to infection caused by gastrointestinal parasites.

O objetivo neste experimento foi avaliar os efeitos do genótipo sobre a composição química e o perfil de ácidos graxos no músculo longissimus dorsi de borregas. Foram utilizados 36 animais dos grupos genéticos: Santa Inês (SI), Ile de France (IF), Ile de France × Santa Inês (IF × SI), Dorper × Santa Inês (DO × SI), Texel × Santa Inês (TE × SI) e Suffolk × Santa Inês (SU × SI). Os animais foram distribuídos em blocos completos casualizados, definidos de acordo com o peso e a idade inicial. Não houve efeito do genótipo sobre os teores de umidade, cinzas e proteína no músculo. A carne das borregas dos genótipos Santa Inês e Suffolk × Santa Inês apresentou menor teor de gordura em comparação à das borregas Ile de France e Ile de France × Santa Inês. Os ácidos graxos identificados em maiores proporções no músculo foram o ácido oleico (C18:1cis), ácido palmítico (C16:0) e ácido esteárico (C18:0). No grupo genético Ile de France × Santa Inês, a relação entre os ácidos graxos poliinsaturados e saturados foi menor que nas borregas Santa Inês e Suffolk × Santa Inês. O genótipo Santa Inês e o cruzamento Suffolk × Santa Inês tem potencial para produção de carne de melhor valor nutricional, devido ao menor teor de gordura e à melhor relação entre ácidos graxos poliinsaturados e saturados.
