  Journal of Dairy & Veterinary Sciences Abstract In species such as the hair, oxidative stress is related to sperm damage during sperm conservation, which affects its fecundity. This research aimed to determine the effect of the addition of melatonin and vitamin E on the levels of Dismutasa-Cu / Zn Superoxide (SOD-Cu / Zn) during the conservation of diluted bristle semen. Seminal maestras of 7 to 18 months old verracos were collected. The optimal parameters are diluted and divided into aliquots: control (with diluent), control with vehicle (diluent and ethanol) and semen with melatonin (1.25 mM) and vitamin E (1 mM. at 16 °C, if enzyme activity (SOD-Cu / Zn), with commercial kit (Cayman®-Chemical Company Ann Arbor, MI, USA) and Hypo-osmotic Test (HOST +), to evaluate the integrity of Plasma membrane Results were analyzed by ANOVA, with SPSS 15.0 statistical package for Windows with p≤0.05 If SOD-Cu / Zn was observed in melatonin-based women, but significantly (p <0.05) high...

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract The availability of indicators that would help to avoid the overvaluation of one of the characteristics involved in the assessment of a good dairy cow over others that are important as well would also allow identifying the most adapted biotypes to the different environments existing at the place of the evaluation This article aims to discuss the need to use several productive and reproductive indicators when measuring the biological efficiency of a dairy cow in grazing systems. It was used retrospective data corresponding to the lactations of 300 primiparous and multiparous cows of the Holstein breed - American-Canadian biotype, along with records of their entire productive life, from their incorporation into the system until their sale or death. The animals were divided into two categories: pure cows (PC, n = 120) and cows in the breeding record (CBR, n = 180). It is observed that there are two different st...

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract The environment of the Bahía Blanca estuary is considered a hot spot in terms of pollution. Bioindicators should have the ability to react relatively fast to certain pollutants and environmental disturbances. Therefore, an exploratory study was carried out determining and quantifying the concentrations of cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb) and zinc (Zn) in the muscle and liver of Mustelus schmitti narrownose smooth-hound and were compared with the values obtained from their respective helminth assemblies. In most of the fishes analyzed, the concentration of heavy metals was higher in the infra communities of cestodes compared to the host. Our results position the cestodes as efficient sentinel species of pollution by bioaccumulating higher concentrations of heavy metals than the host tissues, thus behaving in excellent early warnings of environmental pollution, more real than quantifications...

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract The study was conducted from August 2017 to December 2017 at the Kumasi Abattoir Company Limited to investigate the causes of carcass condemnation in slaughtered pigs and their associated financial losses. Out of the 1221 pigs examined, 212(17.4%) were affected with pathological conditions. The five most frequent pathological conditions were: Lung congestion (7.9%), Ascariasis (2.7%), Cysticercosis (2.4%), Liver congestion (1.1%) and Liver abscess (0. 9%). Pathological conditions were more prevalent (57%) in female pigs than in males (43%). Cross bred pigs were more (81%) affected by pathological conditions than the local Ashanti black pig (19%). The overall carcass condemnation rate was 1.7% with Cysticercosis being the major cause. The average condemnation rate of visceral organs was 1.8 %. Annually, a total of One hundred thousand, six hundred and twenty-eight cedis, seventy-two Pesewas (GHc100, 628.72) w...

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract In the present study we analyzed 55 Pura Raza Chilena horses, from them, 37 males and 18 females clinically healthy, ranging between 5 and 15 years of age, in training for the competition. The objective of this study was to describe the hoof region by means of a morphometric analysis of the angle of the hoof, length of heels and shafts of the frog, obtaining reference parameters that can be used in this particular breed. For the measurement of the angle of the hoof, we used a podogoniometer and for measurement of the length of heels and shafts of the frog a caliper was used. As outcome, it was observed that the angle of the hoof presented an average of 55.88° in the thoracic limbs and 55.46° in the pelvic limbs, without statistically significant differences. The females presented an angle of 54.15° and the males 56.40°, observing significant differences. The results indicate that the heels of the pelvic limb...
