Summary: This article discusses the role of conjugated linoleic acid (CLA) in ruminant dairy products and its regulatory mechanism on milk fat synthesis. CLA has multiple benefits, including anticancer, anti-inflammatory, immune regulation, and lipid metabolism regulation, and it has a positive impact on infant growth and health. The isomer cis-9, trans-11 CLA helps to increase milk fat content, while trans-10, cis-12 CLA inhibits it. CLA is also an important factor in determining the quality of ruminant dairy products.

Summary: Conjugated linoleic acid (CLA) has protective effects against various diseases and can improve human health. The levels of CLA in milk can be increased through grazing feeding, which provides higher amounts of CLA precursors compared to balanced diets. Agronomic practices, such as nitrogen fertilization and regrowth age, can also increase the content of CLA precursors in pastures. This technique of increasing CLA levels in milk adds nutritional value to the milk.

Summary: This study isolated probiotic strains from raw cow milk of the Lahaul valley capable of producing cis-9, trans-11 CLA isomer, and exhibiting antioxidant and food formulation abilities. Genome sequencing revealed the presence of antibiotic-resistance and virulence genes in Enterococcus faecalis LJM:05. The strain Latilactobacillus curvatus LGM:16 was used to develop curdled milk with superior probiotic features, antioxidant activity, and CLA-producing ability.

Summary: This study investigated the effects of feeding Camelina sativa forage harvested at different stages on the milk performance and composition of autochthonous Ionica goats. Results showed that the type of forage had no significant impact on milk yield and chemical composition, but supplementation with Camelina forage led to an increase in milk conjugated linoleic acid (CLA) content. Milk from goats fed Camelina forage harvested during the last three growth stages exhibited higher concentrations of polyunsaturated fatty acids (PUFAs). Furthermore, the thrombogenicity index of milk from the Camelina-fed group was significantly lower compared to the control group, indicating potential health benefits of this forage.

Summary: Camelina sativa fresh forage supplementation in autochthonous goats' diet resulted in milk with higher content of beneficial fatty acids, such as conjugated linoleic acid (CLA) and polyunsaturated fatty acids (PUFA). Additionally, the Caciotta cheese produced from the Camelina group was favored for its better palatability. Further research is needed to explore the effects of feeding Camelina forage obtained from different growth stages and the use of ensiling techniques.

Summary: This study investigated the use of vegetable oils as precursor substrates for developing a dairy product enriched in microbial conjugated linoleic (CLA) and conjugated linolenic (CLNA) acids. Various oils were hydrolyzed and tested, with hempseed, flaxseed, and soybean oils showing the best degrees of hydrolysis. The highest yield of microbial CLNA in milk was achieved with hydrolyzed flaxseed oil, while CLA enrichment was not successful.

Summary: This study analyzed the changes in omega-6 and omega-3 fatty acid content in cool-season grasses. The results showed that different grass species and seasons had varying effects on the concentrations of linoleic acid and linolenic acid. Based on these findings, managing species diversity in pastures to increase and stabilize the content of omega-3 fatty acids in meat and milk products is valuable.

Summary: CLA, a distinctive polyunsaturated fatty acid present in food produced by ruminant animals and accumulated in certain plant seeds, has been shown to have anti-carcinogenic activity. In vivo and in vitro studies have demonstrated its potential to inhibit cancer, with effects such as anti-tumor efficiency, anti-mutagenic, and anti-oxidant activity. While most studies reviewed show beneficial effects on tumor cell proliferation and apoptosis, further experimental work is needed to evaluate the true value of CLA as an anti-cancer agent.

Summary: This study tested three oil-in-water nanoemulsions in two stages. In the first stage, different oils (olive, corn, and linseed) in raw and nanoemulsified forms were used at three levels (3%, 6%, and 9% of dry matter) in rumen batch cultures. The second stage compared the raw and nanoemulsified forms of all three oils at 3% dry matter. The nanoemulsions preserved higher unsaturated fatty acids and had lower saturated fatty acids compared to the raw oils, indicating the ability to decrease the transformation of unsaturated fatty acids to saturated fatty acids in the rumen environment.

Summary: This study found that adding follicular fluid with significantly different fatty acid contents to in vitro maturation media for porcine oocytes affects lipid metabolism in cumulus cells. High fatty acid content in the follicular fluid promotes lipid accumulation in oocytes, while low fatty acid content reduces lipid levels in oocytes.

Summary: This study aimed to assess the risk factors of E. multilocularis infections and describe the clinical course of AE in 36 patients. Results showed that most patients were involved in farming, livestock breeding, forest work, or animal shelters. The majority of patients were diagnosed with E. multilocularis infection within 6 months using imaging and immunoassay techniques. All hospitalized patients initiated anti-parasitic therapy upon diagnosis. The study concludes that regular abdominal imaging examinations and detection of specific antibodies are recommended for individuals at risk, and regular screening tests in hyperendemic areas would improve early detection and clinical prognosis of this life-threatening parasitic disease.

Summary: Studying rabbit milk and its attributes is crucial for breeding practice to ensure the health and growth of rabbit kits. This study analyzed the physicochemical properties of rabbit milk and investigated the impact of reproductive status on milk yield and attributes. The results showed that milk production increased from the 2nd to the 14th day of lactation, while milk composition varied significantly with lactation day and pregnancy negatively affected milk production and composition, as well as kits growth. The findings highlight the importance of understanding rabbit milk for optimal breeding outcomes.

Summary: The popularity of game meat is related to the sustainable management of game species. Game meat is seen as a healthy product obtained from animals that grew in welfare-friendly conditions. However, the popularity of offal from game species in dishes or processed products is lower than muscle tissue and varies among cultures and regions. This study aimed to examine the seasonal variation in body composition, carcass composition, and quality of edible internal organs of fallow deer. The results showed that winter-harvested animals had higher fat content than those harvested in summer. The gastrointestinal tract of summer-harvested deer was more filled with food compared to winter-harvested ones. The season also affected the fat content in the carcass and extractable fat content in the examined offal.

Summary: This study aimed to investigate the effects of including full-fat rice bran in the diet of geriatric horses on their condition, cecal methanogen population, and blood biochemistry parameters. The results showed that adding rice bran to the diet improved the horses' body condition and increased the number of bacteria and methanogens in their cecum. This led to better carbohydrate digestion, nutrient absorption, and increased body weight. There were no significant changes in the horses' hematological and serum biochemistry indices, except for serum globulin levels and the albumin to globulin ratio. Rice bran also affected the horses' serum fatty acid profile.
