SUMMARY Evaluation of the testis size is very important in stallions’ selection, since it an indirect determinant their reproductive potential. The aim this study was to evaluate biometric testicular traits, calculate volume and analyze serum testosterone concentration stallion. During six months were measured tests adults Brazilian Ponies stallions from northern Rio de Janeiro State, Brazil. length, width height testicles (TL, TW TH) measured. From these measurements, total (TTV)...
Abstract We have demonstrated that larvae of codling moth, Cydia pomonella (L) can successfully complete their first instar when fed apple leaves instead fruit. Larvae after hatching maximized feeding intensity (about 320 μg/larva/day) on day 2. Weight gain revealed a stereotypic sigmoid pattern peaked 3. Although the maximum body weight was 70–85% less than for maintained apples or artificial diet, 100% molted to second 3–5 days hatching. Our investigation diurnal leaf ingestion, and...
We present leaf consumption, maximum body weight, head capsule width, and testicular ultrastructure of four sequential instars in codling moth reared solely on apple leaves Honeycrisp variety. The developmental parameters for Cydia pomonella (L.) larvae fed are compared with those artificial diet. Head capsules the second, third, fourth were significantly smaller than Maximum weights lower all More 60% molted to third instar, ≈3% entered fifth but none pupated, demonstrating an inability...
The objective of this study was to evaluate the effect environment on follicular diameter and repeatability size preovulatory follicles mares. Temperature, rainfall, photoperiod were measured, their effects evaluated dynamics. Data studied by analysis variance traits. During five years, 7% double ovulations 159 anovulatory recorded. Mean follicle diameters left right ovaries 39.3±3.8 39.2±3.5 mm respectively. There no evaluation year diameter. Reproduction season affected temperature...
The aim of this study was to characterize the hematological profile equine Brazilian Pony breed herds in northern Rio de Janeiro state, Brazil. Blood samples were separated categories: adult stallions, pregnant mares and non-pregnant mares. red blood cells (RBC), packed cell volume (PCV), hemoglobin (Hgb), main corpuscular (MCV), mean (MCH), concentration (MCHC), white (WBC) differential count basophils (Baso), eosinophils (Eos), band (Bands), segmented neutrophils (Neut), lymphocytes (Lym),...
The aim of this study was to evaluate aspects morphometric, ultrastructural and histological structures present in the ovaries female zebu. We used ten cows. In females that were synchronized, followed standard protocol technique fixed time artificial insemination (FTAI). evaluated before synchronization day surgery with aid ultrasound. On 0 estrous cycle, two animals ovariectomized, while others went through same process their days: D5, D11, D14 D19. macroscopic all considered. had axes...
