The majority of sheep milk produced in the world is transformed into cheese. Feeding a major factor affecting quality and, therefore, Because fat main compound cheese, this review gives an update on effects feeding and nutrition content deeply discusses strategies aimed at increasing levels healthy fatty acids (FA), such as conjugated linoleic acid omega-3 FA, cheese human diet. In addition, use alternative feed resources by-products, aromatic plants, phenolic compounds diet their FA...

Contemporary issues in agriculture and natural resource management (AGNR) span a wide spectrum of challenges scales—from global climate change to resiliency national regional food systems the sustainability livelihoods small-holder farmers—all which may be characterized as complex problems. With rapid development tools technologies over previous half century (e.g., computer simulation), plethora disciplines have developed methods address individual components these multifaceted, problems,...

This review deals with the most relevant limits and developments of modeling intake sheep goats reared intensively extensively. Because small ruminants are normally fed ad libitum, voluntary feed is crucial in feeding tactics strategies aimed at optimal animal production. The effects genetic, neuroendocrine, hormonal, environmental factors on were discussed. Then, several mathematical models to estimate dry matter (DMI) examined, emphasis empirical for intensive farm systems or extensive...

The objective of this study was to characterize the milk yield (MY) and composition relevant sheep goat breeds raised around world be used with nutrition models for diet formulation nutrient balancing. A 2-step approach used. First, a database developed by Food Agriculture Organization identify (i.e., frequently raised) comparing occurrence transboundary breed names across countries. We selected that occurred more than 3 times other obtained from specialized literature had production...

Sixty-four corn silages were characterized for chemicals, bacterial community, and concentrations of several fungal metabolites. Silages grouped in five clusters, based on detected mycotoxins, they being contaminated by (1) low levels Aspergillus- Penicillium-mycotoxins; (2) fumonisins other Fusarium-mycotoxins; (3) high Aspergillus-mycotoxins; (4) non-regulated (5) their Altersetin was clusters 1, 3, 5. Rugulusovin or brevianamide F samples, with the highest concentration cluster 3. Emodin...

The objective of this study was to analyze soil organic carbon (SOC) and environmental footprints—water carbon—in an area livestock intervention located in the high tropics. work conducted La Nevera, Colombia, 03°33′460″ N–76°06’278″ W 03°31′405″ N–76°01’804″ W, between 2700 3300 AMSL. Estimates (t SOC/ha), footprint (kg CO2eq/kg product generated), water (m3 per kg primary product) were made. results obtained were: for forest cover 237,491.91 tons (33 t SOC/ha) average bulk density 0.46...

This study assessed the effects of dietary supplementation with extruded linseed on milk yield and composition, fatty acid (FA) profile renal hepatic metabolism grazing goats in mid-lactation. Forty Saanen were divided into two isoproductive groups: one group was fed control diet (CON) composed hay pelleted concentrate other supplemented additional 180 g/day (LIN; dry matter basis), which supplied 70 fat per head for 9 weeks. Animals grazed pasture ∼3 h/day after first 2 daily milkings. Milk...

The world is continuously transforming to supply growing cities and urbanization processes are still driving important changes in our current food systems. Future sustainability constraints emphasizing that Food Supply Distribution Systems (FSDS) deeply embedded city-region systems with specific technical socio-ecological characteristics. This paper aims provide a systemic understanding on FSDS focusing the integration of urban rural structures considering system biophysical boundaries...

The objectives of this study were to establish if exposure pregnant dairy cows high environmental temperatures and humidity during the first trimester pregnancy impairs establishment ovarian reserve (total number healthy follicles oocytes in ovaries) fertility their offspring. Serum anti-Müllerian hormone (AMH) concentrations ≥3 mm (antral follicle count; AFC) assessed on a random day estrous cycle 310 sixteen-month-old heifers. Based season conception early fetal life, heifers separated...

The world cow milk production will reach between 810 and nearly 1,000 Mt in 2050, implying changes dairy farm management as well implications environmental impact, especially far greenhouse gases (GHG) emissions, nitrogen phosphorus excretions are concerned. future farms need to become smarter, profitable, high yielding continuously improve the sustainability of production. Among western countries, Italian industry has good performances both for yield quality. Most its is used produce highly...

Abstract Three million sheep raised on 10 000 active farms operating in traditional and innovative farming systems Sardinia, Italy, account for 13% of milk production the European Union (EU). Almost all delivered is processed to cheese destined world trade. The Sardinian dairy sector also emits approximately 1600 kt CO 2 eq/year, 60% regional livestock greenhouse gas (GHG), prompting need mitigation plans. SheepToShip LIFE project (EU‐LIFE Climate Change Action 2014–2020) a case study test...

The purpose of this study was to evaluate the effect 6 different feeding systems (based on corn silage as main ingredient) chemical composition milk and highlight potential untargeted metabolomics find discriminant marker compounds nutritional strategies. Interestingly, multivariate statistical analysis discriminated samples mainly according high-moisture ear (HMC) included in diet formulation. Overall, most compounds, identified a function HMC, belonged AA (10 compounds), peptides (71...

Individual dry matter intake (DMI) is a relevant factor for evaluating feed efficiency in livestock. However, the measurement of this trait on large scale difficult and expensive. DMI, as well other phenotypes, can be predicted from milk spectra. The aim work was to predict DMI spectra 24 lactating Sarda dairy sheep ewes. Three models (Principal Component Regression, Partial Least Squares Stepwise Regression) were iteratively applied three validation schemes: records, ewes, days. moderately...

If the world population continues to increase exponentially, wealth and education inequalities might become more pronounced in developing world. Thus, offering affordable, high-quality protein food people will important daunting than ever. Past future challenges increasingly demand quicker innovative efficient solutions. Animal scientists around globe currently face many challenging issues: from ensuring security prevent excess of nutrient intake by humans, animal welfare working with...
