Abstract: the knowledge of the normal appearance and ocular dimensions of goat eyes facilitates the use of ultrasonography in the evaluation of ocular disease. the objective of the present study was to determine ultrasonographic and ecobiometric findings in the eyes of adult goats. b- and a-mode ultrasonography was performed in 30 healthy adult goats (60 eyes) (n=5 intact females and n=15 castrated males). ultrasonography was performed after instillation of a topical anesthetic. lubricating jelly was placed on the 20mhz transducer tip as a stand-off pad. the transducer was placed in a longitudinal position until optimal b-scan images, according to echoes of the a-mode images, were obtained. statistical analysis was carried out to compare the ecobiometric readings among genders (p<0.05). means and standard deviations of the ocular structures for male and female goats, respectively, were, 3.46±0.55, 3.33±0.46mm (anterior chamber depth); 8.60±0.34, 8.65±0.39mm (lens thickness); 11.34±0.61, 11.39±0.66mm (vitreous chamber depth); and 23.43±0.92, 23.39±0.86mm (axial globe length). ocular measurements between right and left eyes, as well as between males and females were not significantly different (p>0.05). the ultrasonographic appearances of goat eyes were very similar to those of other domestic and wild species.

Abstract: the aim of this study was to identify proteins in seminal plasma of goats raised in the northeast of brazil related with precipitation index and semen quality. semen was obtained from three bucks and evaluated to the microscopic and macroscopic parameters. the profile of seminal plasma proteins was performed by analysis of two-dimensional electrophoresis. volume, acrosome integrity and total proteins had significant difference (p<0.05) between the periods of high (1.7ml, 90.3% and 372g ml-1, respectively) and low (1.2ml, 80.3% and 494μg ml-1, respectively) precipitation index. it was detected during high and low precipitation index, 47 and 49 spots of proteins with molecular weight of 4 to 106kda and 15 to 97kda, and isoelectric point of 3.00 to 8.96, and 4.48 to 9.83, respectively. only in the period of high precipitation index were observed groups of proteins with 13kda and 45kda. it can be concluded that semen of alpine american goats raised in the northeast of brazil has best quality when obtained in the period of high precipitation index, which can be attributed to the presence of protein with 13kda and 45kda.

Abstract: the origin and distribution of the ischiatic nerves at both sides were studied in 30 goats (capra hircus) of the saanen breed, being 16 males and 14 females. these specimens were collected after natural death of the animals and submitted to fixation in a 10% formaldehyde solution. the ischiatic nerves arose from the ventral branch of the sixth lumbar and the first and second sacral spinal nerves in 28 cases (93.3%). in addition, these nerves also received contributions from the ventral branch of the third sacral spinal nerve in two cases (6.7%) at both sides. in all animals, the right and left ischiatic nerves gave off branches to the muscles gluteus medius, gluteus profundus, gluteobiceps, gemelli, semitendinosus, and semimembranosus muscles. in particular, peculiar arrangements of these muscular branches were noticed for each specimen. by using the wilcoxon test with significance level at 0.05, there were no significant differences among the frequencies of muscular branches of the ischiatic nerves emitted to the right and left sides, and also in relation to the sex of the goats in the present investigation.

Abstract: the objective of this study was to analyze interactions between different straw sizes and thawing rates on the post-thaw goat semen parameters. twenty-one ejaculates (seven per animal) were collected from three stud bucks by using an artificial vagina. after evaluation, the semen was extended in tris-egg yolk-glycerol and packed in 0.25 and 0.50 ml straws, followed by storage in liquid nitrogen. thawing was performed using two different rates: 37 oc/1 min and 55 oc/7 s. the interaction between the 0.5-ml straw and the thawing rate of 55 oc/7 s promoted higher progressive motility. when the effect of straws alone was analyzed, it was verified that the use of the 0.50 ml straw promoted better conservation than the 0.25 ml one for progressive motility and acrosomal integrity, after the frozen-thawing procedures. optimal results for progressive motility were achieved when goat semen was frozen in 0.5 ml straws and thawed in water at 55 oc/7 s.

Abstract: Background Hybridization between closely related wild and domestic species is of great concern because it can alter the evolutionary integrity of the affected populations. The high allelic variability of Major Histocompatibility Complex (MHC) loci usually excludes them from being used in studies to detect hybridization events. However, if a) the parental species don’t share alleles, and b) one of the parental species possesses an exceptionally low number of alleles (to facilitate analysis), then even MHC loci have the potential to detect hybrids. Results By genotyping the exon2 of the MHC class II DRB1 locus, we were able to detect hybridization between domestic goats (Capra hircus) and free-ranging Iberian ibex (Capra pyrenaica hispanica) by molecular means. Conclusions This is the first documentation of a Capra pyrenaica × Capra hircus hybridization, which presented us the opportunity to test the applicability of MHC loci as new, simple, cost-effective, and time-saving approach to detect hybridization between wild species and their domesticated relatives, thus adding value to MHC genes role in animal conservation and management.

Abstract: the quality, selection, intake, and apparent digestibility of mulberry and star grass in goats, offered fresh or partially dehydrated, were evaluated. the experiment was carried out at the “alfredo volio mata” experiment station of the university of costa rica. harvested forage was fed to 12 saanen, toggenburg and lamancha non-lactating and non-pregnant goats, distributed in a randomized 2x2 factorial design, with an average live weight of 37±5 kg. the treatments were a) fresh star grass, b) partially dehydrated star grass, c) fresh mulberry, and d) partially dehydrated mulberry. forage was offered chopped to the animals. dry matter intake was 0.93, 0.76, 1.17 and 1.12 kg.animal-1. day-1 (±0.09) for fresh star grass, partially dehydrated star grass, fresh mulberry, and partially dehydrated mulberry, respectively. this represented 2.62, 2.09, 3.17 and 3.13% (±0.24) of body weight. crude protein intake was lower with partially dehydrated star grass and higher with fresh mulberry (75.2 vs. 135.4 g.animal-1. day-1). apparent digestibility was not statistically different between treatments; it was on average 49.18% for dm, 59.82% for cp, 57.83% for ndf, and 55.30% for adf. this study demonstrates that the forage species significantly affects voluntary dry matter intake in goats; however, dry matter content of the forages used in this study did not affect dm intake

Chacón, Edilberto;Macedo, Fernando;Velázquez, Francisco;Paiva, Samuel Rezende;Pineda, Eliecer;McManus, Concepta;
Revista Brasileira de Zootecnia , 2011, DOI: 10.1590/S1516-35982011000800007
Abstract: in this work, linear body measures were taken and production indices calculated for 100 cuban creole goats and 100 crossbred goats in order to aid in the characterization of animal genetic resources in cuba. low variation was found for all indices of the creole goats, showing homogeneity between the groups of animals studied. most of the functional indices are related to the milk biotype which is in agreement the possible origin of the breed from animals of the iberian peninsula and canary islands. the crossbreds were more varied, mostly due to undesigned disorganized crossing. these data may help in identifying a commercial niche for the breed and contribute to in situ conservation of the cuban creole goat.

Italian Journal of Animal Science , 2010, DOI: 10.4081/ijas.2005.2s.49
Abstract: Lactoferrin (Lf) is a glycoprotein with a molecular weight of ~80 kDa. It has been isolated from milk and identified in various different mammalian secretions. Several physiological functions have been ascribed to Lf, including regulation of cellular growth and differentiation (Iyer and Lonnerdal, 1993), intestinal iron homeostasis (Levay and Viljoen, 1995), host defense against microbial infection and inflammation (Baveye et al. 1999), regulation of myelopoiesis (Brock, 2002) and protection against cancer (Ward et al. 2002).
