1. Changes in adipose cells of Longissimus dorsi muscle in Iberian pigs raised under extensive conditions
ABSTRACT Twenty-four Iberian castrated male pigs were used to characterize and evaluate the effect of the duration of “Montanera” in the adipocytes size and its relation with the backfat thickness and intramuscular fat. The animals were fed under extensive conditions during 30, 60 and 90 days in the “Dehesa” before slaughtered. Carcass weight, percen

2. CASHEW NUT MEAL USED AS FEED SUPLEMENT IN DIETS FOR LAMBS / UtilizaÃÃo do farelo de castanha de caju como suplemento alimentar em dietas de ovinos
The effects of supplementation with cashew nut meal (CNM) for sheep fed Tifton 85 (Cynodon sp.) grass hay as exclusive forage were evaluated on intake, digestibility, nitrogen balance and ingestive behavior of these animals. For this, we used twenty four male sheep, non-castrated, without defined breed and with an initial body weight (BW) of 16.2 + 3.1 kg an

3. Ractopamine in diets for finishing pigs of different sexual categories
Performance and carcass and cut yield of finishing pigs of three sexual categories fed diets with different levels of ractopamine were studied. Forty-eight hybrid animals (initial weight of 92.1±2.4 kg) were distributed in a completely randomised design in 3 × 2 factorial arrangement (three sexual categories: surgically castrated males, two females and imm

4. Performance and nutritional evaluation of beef cattle raised on pasture, castrated at different ages, with and without supplementation
The objective of this study was to evaluate performance and nutritional traits of beef cattle raised on pastures, castrated at different ages, with and without supplementation. Forty-four crossbred young bulls with predominance of Zebu breed at initial average age of 120±30 days were used in the experiment. Animals were distributed in a completely randomize

5. Exigências e eficiência energética e protéica de ovinos Dorper x Santa Inês alimentados com dietas contendo volumosos de valor nutricional distinto. / Requirements and efficiency of energy and protein use for Dorper × Santa Inês sheep fed diets containing roughages with different nutritive value
The objective of this study was to evaluate the effect of using roughages with different nutritive value on requirements and efficiency of energy and protein use of growing ½ Dorper × ½ Santa Inês sheep. For this purpose, eighty four non-castrated male lambs were weaned at 56 days of age (initial BW = 18.0 ± 3.3 kg) and penned in individual stalls, bein

6. Influência dos hormônios sexuais na analgesia induzida pelo estresse / Influence of sex hormones in stress-induced analgesia
Temporomandibular disorders comprehend a variable group of conditions which result in joint and/or muscle pain and contribute to the development of acute pains, being more prevalent in women than men, especially during the reproductive period. They involve the muscles of mastication and temporomandibular joint (ATM), being usually associated with inflammator

7. Castração, dieta hiperlipídica e DHEA: efeitos sobre a sensibilidade à insulina e secreção em ilhotas isolatas de ratas. / Oophorectomy high fat diet and DHEA: effects on insulin sensitivity and insulin secretion on isolated islets rats.
A privação dos hormônios sexuais, natural ou induzida, contribui para o aparecimento de diversas desordens metabólicas e endócrinas. Esse estudo investigou se a suplementação em dose única com DHEA, esteróide mais abundante em humanos, melhora a sensibilidade à insulina, bem como sua secreção e ou tolerância à glicose em ratas castradas aliment

9. Digestible lysine levels in diets supplemented with ractopamine
In order evaluate digestible lysine levels in diets supplemented with 20 ppm of ractopamine on the performance and carcass traits, 64 barrows with high genetic potential at finishing phase were allotted in a completely randomized block design with four digestible lysine levels (0.80, 0.90, 1.00, and 1.10%), eight replicates and two pigs per experimental unit
