This study was conducted to study the UV protective effect against Haemonchus contortus infection in goats. Sixteen male goats were divided into 5 groups, control infected, control uninfected and UV 30minutes; UV 60minutes and UV booster 60minutes exposure. The UV groups were exposed to UV irradiation at wave length 254nm for 30 and 60 minutes. The UV booster 60min was administrated 2 doses of exposed larvae with an interval of one month. All groups except the control negative one were challenged for 42 days from the beginning. In UV booster60min had reduction in egg count per gram feces and worm burden (93% & 34 % respectively). These parameters were similar in control infected, UV 30min and UV 60min groups. Increases in levels of antibodies were found in goats of UV booster 60min group the other groups. Finally, 2 doses of UV 60min exposure could protect goats from H. contortus.

The vomeronasal organ (VNO) plays an important role in reproduction and social activities in ruminants including goats. A morphological study on the structure of VNO and its epithelial cells was carried out in Korean black goats. Grossly, the VNO of Korean goats opens into mouth through incisive ducts. Microscopically, the epithelium of VNO consisted of medial sensory epithelium and lateral non-sensory epithelium. Several blood vessels and nerve bundles were observed in the lamina propria encased by vomeronasal cartilage. Immunohistochemical staining showed that protein gene product (PGP) 9.5 was immunostained in the receptor cells of the sensory epithelium and in some cells of the non-sensory epithelium. Galectin-3 was mainly observed in the supporting cells of sensory and non-sensory epithelium. Lectins including wheat germ agglutinin, Ulex europaeus agglutinin, Bandeiraea simplicifolia lectin Isolectin B4, Dolichos biflorus agglutinin and soybean agglutinin used in this study were bound in VNO sensory, non-sensory epithelia as well as in the lamina propria with varying intensity. Collectively, this is a first descriptive morphological study of VNO of Korean black goat with special reference to lectin histochemistry.

Fifteen dry dentate and complete mandible samples from the White Rasquera goat breed were studied for symmetry. Thirty-one landmarks were digitally located on the images of the lateral and medial aspects of each hemimandible. Distances between these landmarks allowed the evaluation of the whole hemimandible and also the neural mandible. In the studied samples, the mandible was rather symmetrical, especially in the medial neural part, and in general, there was no side dominance. Only the diastema differed significantly between the sides, and this was related to the rostral part (incisive arch). The incisive region was the least symmetrical region of the caprine mandible, indicating a modular structure more conservative for the neural part. If unsigned asymmetry is interpreted as a measure of developmental stability, then the studied breed presented a marked ability to develop in good fitness despite the harsh environment. The measurements presented here can also be used as a reference for researchers designing experimental studies, especially on mandibular catch-up growth, and as an aid for zooarchaeologists comparing results from dead animals with those from living goat populations.

Objective: To measure florfenicol concentrations in ovine tear fluid after IM and SC administration and determine minimum inhibitory concentrations (MICs) of florfenicol against field isolates of Mycoplasma organisms potentially involved in infectious keratoconjunctivitis. Animals: 9 healthy adult Lacaune ewes. Procedures: Animals received an IM and SC administration of florfenicol (20 mg/kg) in a 2-way crossover design. Samples of blood and tear fluid were collected before and for 24 hours after administration. Concentrations of florfenicol in plasma and tear fluid were measured via high-performance liquid chromatography. The MIC of florfenicol for various Mycoplasma strains cultured from sheep and goats was determined via an agar dilution method. Results: Mean florfenicol concentration in tear fluid for the 24-hour period was significantly higher after IM administration (0.70 μg/mL) than after SC administration (0.22 μg/mL) and was maintained for a longer duration. The lacrimal fluid-to-plasma concentration ratio was not different between the 2 routes of administration, with mean values of 40.2% and 32.5% after IM and SC administration, respectively. The MIC for Mycoplasma agalactiae, Mycoplasma conjunctivae, and Mycoplasma mycoides isolates ranged from 0.5 to 8 μg of florfenicol/mL. Two strains of M agalactiae could be considered resistant to florfenicol. Conclusions and Clinical Relevance: Florfenicol readily penetrated the preocular tear fluid of sheep after IM and SC administration. For both routes of administration, doses > 20 mg/kg would be necessary to achieve tear fluid concentrations of florfenicol greater than the MICs for most strains of Mycoplasma organisms.

This study was conducted with the aim of investigating the
effectiveness of Neem leaf extracts, Azaridachta indica, an indigenous medicinal plant, against helminths of goats. Two extracts were prepared with distilled water using two different techniques; that is, the Neem leaves Water Extract (NLWE) and decoction of Neem
leaves(NLD). This study was carried out using 20 goats from a government farm in Perak. The two extracts showed variable degrees of efficacy in naturally infected goats, as measured by faecal egg count. Further evaluation is required to establish the efficacy.

Four types of products made from Neem namely, neem leaf decoction, neem capsule, neem fresh juice and neem extract were given to 4 groups of goat for a period of 10 weeks to evaluate the effectiveness of these products in controlling natural gastrointestinal helminth infection. During the course of the study, faecal egg counts, Packed Cell Volume and FAMACHA readings were
monitored weekly. Results of feeding these products were variable when compared to untreated control animals, however, a 40-60% worm control was observed. Further testing is required to fine tune these
products for use in the field especially where anthelmintic resistance deems drugs to be ineffective.
