Care in the community? Interpretations of a fractured goat bone from Neolithic Jarmo, Iraq

A case study of a goat metatarsal exhibiting a complex diaphyseal fracture from Pottery Neolithic Jarmo in the Central Zagros region of the eastern Fertile Crescent is here described and analysed. The Central Zagros is one of the areas with the earliest evidence for goat domestication. The significance of the pathology may be viewed within the context of domestic goat ecology in the landscape of Jarmo, potentially impacting browsing behaviour (goats raise themselves on their hind limbs to browse) and movement with the herd in the landscape (the terrain around Jarmo is very steep in places, which would be difficult for an animal to navigate on three legs). In the light of this, possible levels of care that the Neolithic human community may have afforded this animal are discussed – from a situation where therapeutic intervention may have occurred, to one of stall confinement of the animal to allow the pathology to heal, to a position of simple awareness of the condition – and how this impacts on our understanding of changes in attitudes towards animals through the process of domestication.

Physical properties of goat milk powder with soy lecithin added before spray drying

P>In this study, physical characteristics of goat milk powder produced with the addition of soy lecithin at levels of 0 (control), 0.4, 0.8 and 1.0 g lecithin/100 g of total solids in concentrated milk before the spray drying process were investigated. Goat milk was pasteurised, concentrated at 40% of total solids, spray dried and packed in plastic bags under vaccum conditions. Lecithin addition decreased the wetting time of milk powders, although no influence was observed on dispersibility, water sorption, water activity and particle size distribution of the powders. Powders with higher levels of lecithin showed significantly lower brightness, with a greater intensity of yellow colour. It was concluded that lecithin addition before spray drying process at the minimal proportion in concentrated milk of 0.4 g lecithin/100 g of total solids in concentrated milk is useful for achieving more rapid wetting time of goat milk powder.

Surgical treatment of gynaecomastia in a Saanen goat

Background: Gynaecomastia in male goats is characterized by abnormal development of the mammary gland. Enlarged udder may be observed cranially to the scrotum, which can occasionally reach the size of the testicles. The udder may carry functional glands and impair the animal's reproductive performance and welfare. The case of a successful surgical treatment of gynaecomastia in a high reproductive performance Saanen buck-goat is reported in the present study.Material, Methods & Results: The animal was admitted presenting significant augmentation of the mammary glands, which was clinically diagnosed as gynaecomastia. The male goat owned optimal phenotypic characteristics for the Saanen breed, which had been producing high performance descendents. The mammary glands had been impairing the goat's locomotion and sexual performance. Manual milking resulted in great amount of milk secretion. The animal presented anorexia and impaired sexual performance. After clinical and laboratorial evaluation, the animal was submitted to radical mastectomy. An elliptic skin incision was performed around each mammary gland. Subcuticular blunt dissection was accomplished to isolate the mammarian tissue from the abdominal muscular layer and the spermatic chord. The excised mass was sampled for histological assessment. Subcuticular layer and skin closure was carried in a routine fashion. Hygienization of the surgical wound was performed with 2,5% PVP-I solution for ten days. Additionally, an association of penicillin G benzathine and streptomycin, and fluxinin meglumine were also given. The surgical procedure was successfully accomplished without any peroperative complication. The excised mass was sampled for anatomic/histological assessment. Macroscopically, the left mammary gland presented 22 cm in length, 12 cm wide and 26 cm in diameter. The right gland presented 16 cm in length, 7 cm wide and 13,5 cm in diameter. The microscopic assessment revealed hyperplasia of the glandular ducts. No abnormalities resembling malignant mammary neoplasms or degeneration were observed. At the end of the treatment, the animal was completely recovered. The animal convalesced satisfactorily and surgical wound healed completely within the first 10 days post-op. The goat was not culled and returned to normal reproductive activity. Within 12 months of follow-up, the animal was able to produce high milk yield performance progenies.Discussion: This case report presented relevant aspects of the surgical management of gynaecomastia, especially to veterinary practitioners dealing with milk goats. Gynaecomastia is not as common as other reproductive disorders in domestic animals. In opposition to the findings of the present study, other trials revealed that gynaecomastia usually does not affect fertility, libido, ejaculate parameters and sexual performance of goats. However, it is important to consider that neoplasic disorders such as mammary adenocarcinoma may be present, even though these are rare complications. Last but not least, the decision making on mastectomy in the present study was crucial in order to reestablish the animal's welfare and its functionality in the farms reproduction program.

Effect of genotype, finishing system, and sex on physiochemical characteristics of goat meat

Foram utilizados 78 cabritos de ambos os sexos e de cinco genótipos: raça Alpina, ½ Boer + ½ Alpina, ¾ Boer + ¼ Alpina, ½ Anglo-nubiana + ½ Alpina e tricross (½ Anglo-nubiana + ¼ Boer + ¼ Alpina), com peso médio inicial de 14,1 ± 2,5 kg. Objetivou-se avaliar os efeitos do genótipo, do sistema de terminação e do sexo sobre as características físico-químicas da carne. Os sistemas de terminação foram constituídos: ST1 - cabrito + mãe em pasto e ST2 - cabrito desmamado confinado. Os cabritos do ST1 foram mantidos em piquetes formados com Panicum maximum cv. Tanzânia e os do ST2 receberam dieta completa com 16% PB e 73% NDT. Os valores de pH, a* (teor de vermelho), Perda de Peso ao Cozimento (PPC) e porcentagem de Extrato Etéreo (EE) foram influenciados pelo genótipo. Os teores de vermelho (a*) e L* (luminosidade), PPC e porcentagens de umidade, proteína, EE e cinzas foram influenciados pelo sistema de terminação. O músculo longissimus dorsidos animais ½ BA apresentou as melhores características físico-químicas. Se a preferência do consumidor for por uma carne mais macia e com maior teor de gordura, as fêmeas são mais indicadas.

Occurrence of gastrointestinal parasites in goat kids

Amostras fecais de cabritos machos e fêmeas, de diferentes raças e com até uma ano de idade, foram examinadas para determinação do número de ovos e oocistos por grama de fezes (OPG e OoPG, respectivamente) e coprocultura para identificação genérica dos nematódeos. Ovos de helmintos e oocistos de Eimeria spp. foram observados em 93,06% (188/202) e 77,22% (156/202) das amostras, respectivamente. Pelas coproculturas, foram identificados os gêneros Cooperia em 11,88% (24/202), Haemonchus em 51,98% (105/202), Oesophagostomum em 9,4% (19/202), Strongyloides em 5,94 (12/202) e Trichostrongylus em 20,79% (42/202) das amostras. As espécies de Eimeria encontradas foram E. alijevi em 25,24% (51/202), E. arloingi em 7,42% (15/202), E. caprina em 2,97% (6/202), E. caprovina em 10,39% (21/202), E. christenseni em 4,45% (9/202), E. joklchijevi em 11,38% (23/202), E. hirci em 9,4% (19/202) e E. ninakohlyakimovae em 28,71% (58/202) das amostras.

ULTRASTRUCTURE OF THE GERMINATIVE EPITHELIUM IN A GOAT WITH A 5/15-ROBERTSONIAN TRANSLOCATION

The spermatogenesis of two goats bearing a 5/15 Robertsonian translocation was investigated by electron microscopy. There was no dramatic change in the morphology of the cells of the spermatic line. All cells of the seminiferous epithelium seemed quite normal at the ultrastructural level. However a certain disturbance in the cell localization and some morphological abnormalities involving nuclear structure were seen. Spermatocytes and spermatids normal in appearance were observed, but a great number of cells presented two or more nuclei. These cells were frequently seen to become degenerated during spermatogenesis. We believe that unbalanced spermatocytes degenerate during the process and only some spermatocytes succeed in fertilizing gametes.
