The area of research is supported by oil palm plantations, palm plantations, agricultural land, forestry land, vacant land that has not been explored by farmers and other vacant land. The study was conducted by the method of field survey, according to information from the local Animal Husbandry Department, the criteria in the data is the cattle population in farmer.The purpose of this study was to determine the economic analysis on a group of cattle ranchers. Primary data and secondary data were analyzed using descriptive tabulation, quantitatively and economically. The results of the research effort shows that beef cattle, ranchers group profit amounted Rp.3.637.500/year, Agung Sindo  Village B/C ratio of 1.2, Kalaenaliri village of Rp.3.886.000/ year ratio B/C 1.2, and the Wanasari Village of Rp.3.788.000/year and ratio of B/C 1.2. Forage in locations very research support to the development of beef cattle Bali. But farmers are accustomed way of raising beef cattle between 2-4 head/breeder, so it needs additional maintenance business scale between 5-10 cattle/livestock farmers, so that the business more effectively and efficiently and economically will benefit farmers.

One of the Acehnese traditional food  preserved by the addition of salt, acid and dried was sie balu. The preservation method may lead to changes in the structure and nutritional content. Sie balu with the addition of vinegar, garlic and ginger can reduce the value of water activity (aW), pH and bacterial counts. This condition affects the physical properties and sensory of sie balu. Irradiation can control pathogenic microorganisms in meat without affecting the physical condition. Low-dose irradiation is able to maintain the desired sensory attributes nutritious food products. This study aims to determine the characteristics of the sensory and physic sie baluthat irradiated with increasing doses and the shelf life of 3-6 weeks. Sie balu was made of 10 kg fresh beef, dried in the sun to dry, vacuum and irradiated at doses of 5, 7 and 9 kGy. Sensory test conducted by taste sie balu by trained panelists and fill out the hedonicform. The physical properties based on pH and aW.

The study concluded that irradiation can improve the physical properties, sensory and microorganisme reductionof sie balu.

abstract

Toxoplasmosis is one of the most common zoonoses worldwide. It was initially described in rodents and rabbits. There are few data on the morbidity and mortality of this disease among Brazilian marsupial fauna, such as opossums. These animals are of great importance regarding the epidemiology of this disease, given that they are prey for felids and other carnivores. With the aim of ascertaining the serological response to Toxoplasma gondii among marsupials (Didelphis spp.), 38 animals that had been caught in 14 districts of the urban area of the municipality of Bauru, state of São Paulo, were evaluated. The modified agglutination test (MAT) showed that 26.3% (10/38) of the samples analyzed were seropositive. It can be suggested that the opossums’ behavior and persistent proximity to human housing results in contact with cats and T. gondii infection, based on the frequency found in this study. This was the first study on the seroprevalence of T. gondii in opossums caught in the urban area of the municipality of Bauru, SP, and it highlights the need for environmental and health authorities of the municipality to monitor this zoonosis.

Sie balu is an Acehnese dried meat preserved by the addition of salt, acid and dried. However, long processing and drying it under the sun can cause meat products contaminated by Salmonella. Irradiation can eliminate  Salmonella  and  other  pathogenic  bacteria  in  food.  This  study  aims  to  determine  the  presence  of Salmonella in sie balu after irradiated with increasing doses and 2 to 4 months shelf life. Sie balu was made of 5 kg fresh beef, dried under the sun to dry, vacuum and irradiated at doses of 5, 7 and 9 kGy. Salmonella was detected using bacteriological and biochemical tests. Results showed sie balu contaminated by Salmonella paratyphi B and Salmonella cholerasuis. The irradiation and shelf life significantly affect (P0.05) the count of Salmonella in sie balu compared with unirradiated one. Irradiation doses of 5, 7 and 9 kGy do not affect the count of Salmonella in sie balu. Extending the shelf life up to 4 months can increas the count of Salmonella. This study concluded that irradiated sie balu at doses of 5, 7 and 9 kGy can be stored for up to two months

This study was carried out to assess the prevalence of gastrointestinal nematode in cattle in the Pintu Rime Gayo, a highland sub district of Bener Meriah Regency, Aceh according to age and sex. Stool samples were collected from 150 cattle aged 0-6, 7-12 and 12 months old. Examination was performed by using a centrifuge. Samples tested positive when found gastrointestinal nematode parasite eggs. The data obtained were analyzed with Chi-Square. The results showed that the prevalence of gastrointestinal nematode in cattle aged 0-7 months (32%) was significantly higher (p0.05) than that in cattle aged 7-12 months (22%) and 12 months (12%). The parasite was markedly more prevalent (p0.05) in female cattle (23.9%) than that in male cattle (15.2%). In conclusion, susceptibility of cattle in the Pintu Rime Gayo highland to gastrointestinal nematode infection was influenced by both age and sex.

The aim of this study was to determine the effects of severe extreme thermal stress on the respiratory rate (panting) of unsheared and sheared rams in standing and lying position, and to analyse two temperature-humidity indices (THIs). Six mature Australian Merino rams from Northern Patagonia, three unshorn and three shorn, were subjected to 40 hours (8 hours each day for five days) of gradual increase in temperature from 25°C to 40°C, guaranteeing 4h daily at 40°C in a heat chamber. Respiratory rate (RR) was registered continuously by counting flank movements, and the ambient air temperature and relative humidity were recorded every five minutes inside the heat chamber. From 1413 RR measurements, descriptive and modelling analyses were performed. Panting as a response variable was distributed into five categories, and fixed effects such as THI, wool (unshorn/shorn), and position (standing/lying) were considered. No significant differences were observed between the panting score in the unshorn (standing or lying) and standing (unshorn or shorn) sheep, but significant differences were observed in shorn and lying rams. The explanations could be that heat production from muscle activity was lower and the transfer and heat lost by conduction to the floor was easier in the rams with shorter fleece (at least 0.7 inches long). However, in the unshorn rams, their wool acted as an insulator, both with air as well as the floor. Australian Merino rams from Northern Patagonia are heat tolerant to an environment between 31.5°C and 42°C, and 32% to 48% humidity for 40 hours over five days. The rams were in the first phase of panting, and the normal rectal temperatures registered daily when leaving the heat chamber confirmed that regulation of body temperature was possible. The LPHSI’s THI was adjusted to improve the analysis of the RR more than the National Research Council’s THI.

Estrus synchronization is a reproductive biotechnology used to improve artificial insemination or pairing through the manipulation of the estrous cycle at a desirable time. Employing this technique in captive pacas (Cuniculus paca L.) is important because it creates expectation of meeting the demand for paca meat and, consequently, reduces poaching. Thus, this research aims to verify the effect of a progestogen implant associated with two doses of eCG on the synchronization and induction of fertile estrus. Twenty-seven adult pacas were used, 18 non-pregnant females and nine males, divided into three groups. G1 and G2 females groups (treatments) received 1.5 mg Norgestomet and were injected intramuscularly, seven days later, with 0.13 mg of prostaglandin. After 24 hours the implants were removed and the animals immediately received 25 IU and 50 IU of ECG intramuscularly, respectively. The mating of the three groups took place on the same days. G3 females’ group (control) showed estrus on different days after D0. Females under treatment displayed estrus only after removing the implant (D8). G1, G2, and G3 pregnancy rates were 100%, 66%, and 50%, respectively. Regarding births per parturition, 100% of G1 and G3 produced one offspring, while 50% of G2 produced two. Progestogen in the form of subcutaneous implants was effective in mimicking the luteal phase of the estrous cycle. After removal, implants favored the occurrence of a fertile estrus. As a conclusion, further studies must be conducted in order to establish in-depth possible association between 50 IU of eCG, and the occurrence of twin pregnancies.

During fertilization, spermatozoa interact with the zona pellucida (ZP) through the binding between the acrosome and proteins 2 and 3 (ZP2 and ZP3). The perivitelline membrane of chicken egg yolk is homologous to the mammalian ZP3, which allows the binding of sperm of several species. The aim of this study was to standardize and evaluate the efficiency of sperm-binding to the perivitelline membrane of chicken eggs as a functional method for canine semen evaluation. For this purpose, nine post-thaw sperm samples were used, which were divided into two aliquots: the first was kept in water bath at 37ºC (live sample) and the second was submitted to cold shock to induce cellular damage (dead sample). The two aliquots were mixed on five proportions, corresponding to 0%, 25%, 50%, 75%, and 100% of viable cells, and the binding test was performed by analyzing the number of spermatozoa bonded to the perivitelline membrane by means of computerized assessment of sperm motility (CASA) or conventional microscopy. Additionally, samples were submitted to sperm motility analysis, evaluation of plasmatic and acrosomal membrane integrity, and sperm mitochondrial activity. The sperm-binding test to the perivitelline membrane of chicken egg yolk was considered a feasible sperm analysis test for both fertilizing capacity and overall sperm attributes evaluation, mainly when the analysis is performed by a conventional microscope, which expands its practicality to the majority of canine reproduction laboratories.

The goal of this study was to describe the anatomy of the femoral artery in wild canids such as the crab-eating fox (Cerdocyon thous), the hoary fox (Lycalopex vetulus), and the maned wolf (Chrysocyon brachyurus). Two specimens from each canid group were used. Red dyed latex was injected in the arterial system of the animals, which were then fixed in 10% formaldehyde aqueous solution and dissected following the routine techniques in macroscopic anatomy. In the three canid groups, the arterial pattern was similar to that described for domestic canids, in which the deep femoral artery rises from the external iliac artery, still in the abdominal cavity, and sends its first branch, the lateral circumflex femoral artery. A few muscular branches, one or two caudal femoral arteries, and the terminal branches – the descending genicular artery, the saphenous artery, and the popliteal artery – are all originated from the femoral artery. The origin pattern of these vessels also shows similarities with those from domestic canids, sometimes forming trunks and occasionally rising individually. Thus, it can be concluded that the anatomical pattern of the femoral artery and its branches in wild canids shows similarities with that from domestic canids, but inherent variations in each species are also present.
