Enhancing sausage functionality products for school-age children: a study on goat and camel meat with natural purslane powder as an antioxidant additive

The objects of the study are goat and camel sausage with the addition of the natural antioxidant purslane powder. Goat and camel meat are rich in protein, contains little fat and has good digestibility, which makes it an attractive product for baby food. The results showed that experimental samples of goat sausage and chicken fillet and goat sausage and camel sausage showed a moisture content of 72.7 % and 70.6 %, fat 8.1 % and 6.7 %, protein 13.41 % and 15.31 %, carbohydrates 3.0 % and 4.4 %, respectively. The moisture binding capacity of goat and chicken fillet sausage with purslane is 78.16 %, which is 1.73 % higher than the benchmark, which is 76.43 %. The moisture binding capacity of goat and camel sausage with purslane was 78.65 %, which is 2.22 % higher than in the control. High moisture-binding ability helps to preserve the freshness and taste of sausage for a long time. In the course of the work, a comparative analysis of the digestibility of proteins of experimental samples of boiled sausage products was carried out. It was found that goat sausage and chicken fillet are characterized by a lower concentration of tyrosine due to the action of proteolytic enzymes (pepsin and trypsin) – from 624.6 mcg/ml (during the first three hours of hydrolysis) to 371.3 mcg/ml (during 6 hours of hydrolysis), against sausage made from goat meat and camel meat 674.2 when digested with pepsin and 377.3 when digested with trypsin, which indicates a higher degree of digestibility of proteins of these products. Thus, the research of goat and camel sausages for school-age children can contribute to the creation of innovative products that will meet the needs of children's health and development, as well as contribute to the sustainable development of rural regions and the growth of economic activity

Effect of DHCR7 on adipocyte differentiation in goats

Cholesterol is regarded as a signaling molecule in regulating the metabolism and function of fat cells, in which 7-Dehydrocholesterol reductase (DHCR7) is a key enzyme that catalyzes the conversion of 7-dehydrocholesterol to cholesterol, however, the exact function of DHCR7 in goat adipocytes remains unknown. Here, the effect of DHCR7 on the formation of subcutaneous and intramuscular fat in goats was investigated in vitro, and the result indicated that the mRNA level of DHCR7 showed a gradual downward trend in subcutaneous adipogenesis, but an opposite trend in intramuscular adipogenesis. In the process of subcutaneous preadipocytes differentiation, overexpression of DHCR7 inhibited the expression of adipocytes differentiation marker genes (CEBP/α, CEBP/β, SREBP1 and AP2), lipid metabolism-related genes (AGPAT6, FASN, SCD1 and LPL), and the lipid accumulation. However, in intramuscular preadipocyte differentiation, DHCR7 overexpression showed a promoting effect on adipocyte differentiation marker genes (CEBP/α, CEBP/β, PPARγ and SREBP1) and lipid metabolism-related genes (GPAM, AGPAT6, DGAT1 and SCD1) expression, and on lipid accumulation. In summary, our work demonstrated that DHCR7 played an important role in regulating adipogenic differentiation and lipid metabolism in preadipocytes in goats, which is of great significance for uncovering the underlying molecular mechanism of adipocyte differentiation and improving goat meat quality.

Integrated Metabolomics and Transcriptomics Analyses Reveal the Candidate Genes Regulating the Meat Quality Change by Castration in Yudong Black Goats (Capra hircus).

Yudong black goats (YDGs) are a local breed in southwest China that possess unique meat qualities and produce a high meat yield, making them ideal models for studying goat meat quality. Castration may decrease off-odors, significantly change metabolites and improve meat quality. Using multi-omics techniques, this study focused on Yudong black goat wethers (YDW, n = 4) and Yudong black bucks (YDB, n = 4). The findings revealed that 33 differentially expressed genes (DEGs) and 279 significantly changed metabolites (SCMs) influenced goat meat quality by affecting fat accumulation and lipolysis regulatory processes. Herein, several candidate genes (IGF1, TNNT2, PPP2R2C, MAPK10 and VNN1, etc.) were identified that play a role in regulating meat quality, non-castrated and castrated, alongside a series of metabolites that may serve as potential meat quality biomarkers. Lipids (triglycerides, oxidized lipids_5-iso PGF2VI, ceramide (t18:1/36:2(2OH)) and Carnitine C20:5, etc.) were significantly higher in the castrated goats. These results revealed that lipids and hydrophilic metabolites were affected by castration, which might be beneficial in terms of goat meat quality. This study aimed to investigate the differences in meat quality between uncastrated and castrated male goats and the possible molecular regulatory mechanisms.

Moroccan and Spanish agriculture comparative analysis 2008-2021

In the general context of Morocco's New Development Model, where public policies need all their credentials, and more specifically in the context of Morocco's new agricultural strategy (Green Plan), the challenge is to develop modern agriculture with high added value and high productivity, capable of competing with agricultural production in other countries. This article compares the overall characteristics of agricultural production in Spain and Morocco. To make this comparative analysis, we have focused on a set of agricultural statistical aggregates, such as cultivated area, level of production and yield in relation to each family of agricultural products. These are calculated, using the Laspeyres index, over the period 2008 to 2021. In addition, we have chosen 2008 as the base year for plotting the evolution of Moroccan agricultural performance against that of Spain. The results of our comparative analysis showed that agriculture in Spain is more stable than in Morocco, particularly in cereals and fresh vegetables. Thus, they showed that the majority of Spanish agricultural products outperform those of Morocco. On the other hand, this comparative analysis showed that Moroccan agriculture outperforms Spanish agriculture in the production of sheep, apples, fresh peas, carrots, turnips, broad beans, green beans, goat meat, dried lentils and chickpeas, and that Moroccan agriculture outperforms Spanish agriculture in the production of dates and unshelled peanuts.

Knowledge, Attitude, Hygiene Practices, and Enumeration of Salmonella from Raw Meat at Retailer Shops in Chelenko Town, Eastern Ethiopia

Aim Salmonella has been identified as the primary contributor to foodborne illnesses, posing a significant public health issue due to its high contamination rates. Methods A cross-sectional study was conducted from July 2022 to December 2022 to isolate and determine the burden of Salmonella in goat meat at retail shops and to identify knowledge, attitudes, and hygienic practices in Eastern Ethiopia. A total of 224 samples were collected from goat meat, and environmental samples (cutting board, knife, worker’s hand, and hook) were examined for the prevalence of Salmonella using conventional microbiological procedures. All samples underwent serial dilution to determine Salmonella loads in goat meat from the retailer’s houses. Additionally, 33 retail shop workers with different demographics were interviewed regarding their knowledge, attitudes, and practices related to Salmonellosis. Results The results revealed that out of 224 goat meat and environmental swab samples examined, the prevalence of Salmonella was 26.78%, 31.6%, 19.6%, 22.2% and 15.8% for goat meat swabs, cutting boards, hand swab samples, knife, and hook swab samples, respectively. The total average loads of Salmonella on different samples were found to be 6.88×105 cfu/mL, 6.09×105 cfu/mL, 6.51×105 cfu/mL, 4.59×105 cfu/mL and 3.28×105 cfu/mL for meat swab samples from retailers, hand swab samples, cutting boards, knife swabs, and hook swab samples, respectively. Conclusion The study showed that the hygienic status of retail shops in the study area is poor, and the prevalence and load of Salmonella are high. Based on these results, it is recommended to raise awareness to reduce the prevalence of Salmonella in goat meat and decrease bacterial loads. Additionally, the responsible authorities should coordinate with retailers and shops to enforce good hygienic handling practices.

Prevalence and antibiotics resistance status of Salmonella in raw meat consumed in various areas of Lahore, Pakistan

This study reports the prevalence and antibiotics resistance status of Salmonella detected in raw meat from Lahore, Pakistan. Overall, N = 111 meat samples, were collected from local markets. Salmonella was recovered from 57 (51.35%) samples, including 45.83% of poultry, 60% of buffalo, 64.28% of cow, and 60% of goat meat samples. The predominant Salmonella strains were Salmonella enterica serovars; Typhimurium (45.4%), Typhi (27.2%), and Enteritidis (18.1%), identified by VITEK system and 16S rRNA gene sequencing. The isolates exhibited high resistance to Erythromycin (100%), Cefepime (98.24%), Colistin (94.73%), Azithromycin (92.98%), Tetracycline (87.71%), Polymyxin B (84.21%), Ciprofloxacin (84.21%), Trimethoprim-Sulfamethoxazole (80.70%), Nalidixic Acid (80.70%), Kanamycin (78.94%), Chloramphenicol (77.19%), Streptomycin (71.92%) and Ampicillin (64.91%). While the isolates exhibited more susceptibility to Meropenem (75.43%) and Amikacin (73.68%). N = 8 strains were designated as Multidrug Resistant (MDR) and N = 3 as Extensively Drug-Resistant (XDR) Salmonella. The PCR-based detection of resistance genes revealed the presence of blaTEM-1 gene (100%), catA1 gene (64%), and gyrA gene (18%). The whole genome sequencing (WGS) of two selected strains and subsequent downstream analysis confirmed the strains as MDR and XDR Salmonella enterica serovar Typhi. The study showed that raw meat consumed in Lahore carries a significantly high number of drug-resistant Salmonella.

Microbial Study of Pathogenic Bacterial that Producing Biofilm Isolated From Fresh Red Meat

Contamination of meats with different species of microorganisms pose significant threats not only to the human health but also to the animal production. This study was conducted to investigate the presence of bacterial contaminants in raw meat of livestock. A total of 75 random samples were collected (included 50 cow samples and 25 goats samples) from several butcher shops and slaughterhouse stores in Basrah governorate. The samples were subjected into the biochemical tests using Enter system 18R to confirm preliminary bacterial diagnosis and subsequently cultured using a selective media (MacConkey agar). The outcomes demonstrated Escherichia. coli was the dominate bacterial isolated species in the cow and goats with the percentage estimated at (30%) and (28%), respectively. Other important isolations were also found Enterobacter cloacae in was a rate (20%) Cow meat and Klebsiella pneumonia in goat meat with a rate estimated at (20%), while the lowest isolations rate was Salmonella spp (8%) in cow meat. Staphylococcus aureus (14%) in cow meat and (12%) in goat meat. In conclusion, meats are representative the source of infection with foodborne pathogens carry hazard to public health transmitted to the humans due to mishandling and improper hygienic condition of meats. The results showed biofilm production were high percent for Staphylococcus aureus 5 (50%) strong biofilm producer, follow Klebsiella pneumonia 4 (30.76%) strong biofilm. As other isolates were biofilm producer and production of biofilm is related to the resistance.

Investigation of goat meat consumption in relation to market potential among major stores in Eastern Cape, South Africa

There is low commercial availability of goat meat in retail outlets such as supermarkets and butcheries due to the limited supply and cultural beliefs in many nations of the world, especially in sub-Saharan Africa. This study aimed to find potential customers for goat meat if it were made readily available in retail outlets. Two hundred respondents from cities and towns (Port Elizabeth, East London, Mthatha, King’s Williams town, Grahamstown, Alice, Butherwotth, Fort Beaufort, Queenstown, Craddock, Adelaide, Port Alfred, Stutterheim, and Peddie) in the Eastern Cape, South Africa, were randomly selected and interviewed using structured Google form questionnaires. Data were analyzed using descriptive statistics and chi-square tests. Participants answered questions about goat meat consumption in relation to other meats. Factors limiting the consumption of goat meat were also investigated. About 66% of respondents had positive views of goat meat, while 23.5% were neutral. Only 10.5 % had unfavourable views concerning goat meat. The availability of goat meat in the market was the most limiting factor for 60% of the respondents, while 15% said price was their limiting factor. Other factors limiting goat meat consumption were personal preferences, religion, aversion to testing, price of goat meat, aversion to smell, and fattiness, with 15%, 9%, 6.5%, 5%, 4%, and 0.5% of respondents, respectively. About 46% of the total respondents preferred goat meat from a supermarket or butchery, and only 6.5% preferred vendors. Only 26% preferred live goats, while 61.5% preferred a portion of meat from slaughtered goats. The chi-square test also revealed a significant association (P<0.05) between attitude/view of goat meat consumption with gender (0.00), age (0.001), nationality (0.027) and ethnicity (0.041). However, the association between attitudes/views towards goat meat consumption and small households (0.262) or religion (0.142) was not significant (P>0.05). Although demand for goat meat is expected to rise as people receive more information on nutritional benefits and cooking methods, it could be concluded that consumers are willing to consume it and that there is market potential for it as a major store product.

The development and consumer acceptance of goat meat burger patties and sausages among young adults in Kwazulu-Natal, South Africa

Although goat meat is a nutritious and sustainable Animal Food Source (AFS), it is not commonly preferred as an AFS in sub-Saharan Africa even though goats thrive in the region. To explore the potential of promoting goat meat consumption among young adults in KwaZulu-Natal, South Africa, an experimental study was conducted involving the development, nutrient analysis and microbial testing of two goat meat products through a series of recipe development trials. This study aimed to use food processing techniques to improve the sensory qualities of goat meat (texture and aroma) in value-added products. Goat meat patties and sausages were developed and evaluated for consumer acceptance using Check-All-That-Apply (CATA) food action rating scale and paired preference testing (n=100). Results from the nutrient analysis showed that both the patty (31.57g/100g) and the sausage (26.88g/100g) were high in protein. The total fat content for each sample was less than 10g per 100g portion.The coliform counts for both samples were very low and well within the acceptable range. The yeast and mould counts were very low, and total bacterial counts were low and within an acceptable range. The CATA test revealed the most frequently selected term used to describe the sensory attributes were ‘smoky’ for aroma (82%, 55%), ‘brownish-grey’ for appearance (68%, 80%), ‘meaty’ for flavour (92%, 86%), and ‘tender’ for texture (59%, 51%) for the goat meat patty and sausage, respectively. Participants showed a more positive attitude towards purchasing and consuming the goat meat patty (96%) than the goat meat sausage (88%). Both products received positive sensory feedback. However, the majority of the participants preferred the goat meat patty (66%) over the sausage (34%). The findings suggest that promoting goat meat consumption in South Africa can be achieved through the introduction of value-added convenience products like the goat meat patties and sausages developed in this study. Key words: Goat meat, goat meat patty, sausages, young adults, consumer acceptance

Prevalence of Zoonotic Intestinal Parasites in Meat Goats in Southern Thailand.

Background: Intestinal parasites not only lead to poor goat health and productivity but can also affect human health. We investigated the distribution of zoonotic intestinal parasites among goats in southern Thailand to assess the human health risks. Materials and Methods: Overall, 561 fecal samples were collected randomly from goats in farms (55) in Songkhla, Satun, Pattalung, Pattani, Yala, and Narathiwat provinces between January 2020 to January 2022. Parasite eggs were detected via the standard protocol formalin ether concentration technique (FECT). Results: Samples containing one or more intestinal parasites accounted for 97.33% (543/561) of the total samples, and the percentage of zoonotic parasite was 80.04% (449/561). Among the positive samples, two types of zoonotic helminths were identified, Strongylid egg type (79.32%) and Fasciola spp. (2.14%). Strongylid egg type was highly abundant in samples from Satun (84.62%), Songkhla (82.74%), Pattalung (79.31%), and Yala (77.27%). Fasciola spp. was mostly found in samples form Pattalung (13.79%) and Songkhla (1.12%). Eimeria spp. was the mostly identified protozoa 25.67%. It was mostly identified in samples from Narathiwat (75%), Pattani (41.9%), and Songkhla (31.41%). Mixed infections accounted for 40.82% of the total with 33 patterns. It was found that Strongylid egg types occurred in 28 patterns (84.85%). Strongylid egg types-Eimeria spp.-pattern was the most commonly found. Conclusion: Based on the results, zoonotic helminth infection was found together with widespread and high diversity of intestinal parasites infection in meat goats, which affect animal health and may pose a risk to human health. Mass deworming programs with a proper anthelmintic drugs and good agricultural practices need to be encouraged by the government so that people who contact with goats should practice good hygiene behavior. Farm management should be applied by intensive goat raising with pasture circulating to reduce parasite egg contamination. Moreover, fresh fertilizers from goat faces should be avoided.

Bioaccumulation of radionuclides in hoofed animals inhabiting the Semipalatinsk Test Site.

The article assesses the content of radionuclides in hoofed animals inhabiting the Semipalatinsk Test Site by calculation. Hoofed animals' faeces were sampled to determine the content of radionuclides in their diets. Based on values determined for the content of radionuclides in animals; diets, the content of radionuclides in the meat and milk of farm animals-cows (Bos taurus taurus), sheep (Ovis), goats (Capra hircus) and horses (Equus caballus Lin., 1758) as well as in the meat of wild animals-european moose (Alces alces Lin., 1758), argali (Ovis ammon Lin., 1758), roe deer (Capreolus pygargus Pal., 1771) and saiga (Saiga tatarica Lin., 1766) was calculated. No excess of permissible values of the content of 137Cs and 90Sr in the meat of farm animals was found to be expected, even for a conventional 'conservative' scenario, in which maxima of the radionuclide activity concentration in a vegetable feed (faeces) are taken as a basis. 241Am and 239+240Pu in the meat of farm hoofed animals are not standardized. Their predicted maxima of activity concentration are very low, and even in the 'conservative' scenario, they do not exceed 1.8×10-2 Bq kg-1, 1.4×10-1 Bq kg-1 and 1.6×10-1 Bq kg-1, respectively. In the milk of farm animals, the content of 137Cs and 90Sr does not exceed permissible values. 241Am and 239+240Pu in the milk of farm animals are not standardized. Their predicted activity concentration values in the milk of sheep and goats do not exceed 6.5×10-2 Bq l-1, for cows- 2.6×10-2 Bq l-1, for horses- 3.1×10-2 Bq l-1. Permissible values of 137Cs and 90Sr in the meat of wild hoofed animals are not exceeded either. In the meat of argali, roe deer and saigas, relatively high levels of 137Cs are predictable. 241Am and 239+240Pu in meat of wild animals are not standardized. Their predicted activity concentration values in the meat of moose and argali do not exceed 3.2×10-1 Bq kg-1 and 1.6×10-1 Bq kg-1, respectively, for roe deer and saiga-5.4×10-2 Bq kg-1. Thus, in case of free grazing in the STS territory, no excess of permissible values of standardized radionuclides (137Cs and 90Sr) in the meat and milk of hoofed animals is predictable.

Morphology and reproductivity profiling of male Senduro goats based on age differences

Senduro goats, a local breed of meat and dairy goats from Indonesia, are recognized for their significance in improving goat breeding and preserving valuable genetic resources. However, limited information exists regarding the reproductive physiology of Senduro goats, which poses challenges to the development of breeding programs and the preservation of genetic resources. This study aimed to investigate the morphological and reproductive profiles of male Senduro goats at different ages, focusing on morphological characteristics, mating behavior, and sperm quality. Morphological characteristics are assessed through body length measurements, while mating behavior serves as an indicator of reproductive behavior. Macroscopic evaluations of sperm quality include assessments of color, viscosity, pH, and volume, while microscopic examinations encompass motility (mass and individual), viability, and spermatozoa membrane integrity. The results showed morphological similarities between juvenile and adult samples, with their testicular size being the only significant difference. Based on macroscopic and microscopic examinations, no significant differences were found between groups. From the results it was concluded that there were no distinct differences in morphological characteristics, mating behavior, and sperm quality between male Senduro goats in the juvenile and adult stages.

Goat Livestock Business Potential Viewed from Population and Production in Indonesia

Judging from the development aspect, the goat livestock business is very potential, easy to cultivate, both daily and commercially. Goats have several advantages and economic potential, their bodies are relatively small, they reach maturity quickly, and they are easy to maintain. Goat farming business is very easy, does not require large areas of land, relatively small business capital investment, easy to market and business capital rotates quickly.This paper aimed to determine the potential for goat farming in terms of the population and production of goats in Indonesia. This paper examines quantitative data from the last 5 years. The results show that the demand for goat meat in Indonesia is quite high because goats are one of the most consumed livestock by the people of Indonesia, the high level of demand is inseparable from the function of goat farming.
