Effects of the inclusion of ground Pouteria sapota kernel on intake, digestibility, and growth performance in lambs
Simple Summary: The concept of sustainable diets that are profitable, ethical, socioculturally acceptable, and environmentally beneficial is emerging as one of the key solutions to ensure the efficiency of livestock production systems. In this regard, agro-industrial by-products obtained from fruit processing have emerged as an alternative. Mamey pulp generates residual biomass from which the kernel is the main by-product that, due to its composition, can be used as ruminant feed. This study determined the effects of the inclusion of ground mamey kernel on intake, digestibility, and growth performance in lambs. No effects on nutrient intake or productive performance were observed. However, protein and fiber digestibility were reduced by ground mamey kernel inclusion. These findings suggest that mamey kernels can be included in ruminant diets. Abstract: This study determined the effect of replacing ground corn and soybean meal with ground Pouteria sapota kernel (PSSM) in lamb diets on nutrient intake and digestibility, performance, and carcass traits. Twenty-one male hair sheep lambs with an average body weight of 22 ± 3.5 kg were randomly assigned to three treatment diets containing PSSM at 0, 10, and 20% of the total dry matter (DM) inclusion. The study lasted 60 days, which included 15 days for adaption and 45 days for sample collection. The PSSM inclusion did not affect intake or performance (p > 0.05). However, ether extract (EE) digestibility linearly increased (p < 0.0001), while crude protein (CP) and acid detergent fiber (ADF) linearly decreased. Final body weight, total weight gain, average daily weight gain, feeding efficiency, and carcass traits were not affected by PSSM inclusion. In conclusion, these results suggest that PSSM can replace up to 200 g/kg DM of ground corn and soybean meal without affecting intake or animal performance

Using plant-based compounds as preservatives for meat products: a review
The susceptibility of meat and meat products (MP) to oxidation and microbial deterioration poses a risk to the nutritional quality, safety, and shelf life of the product. This analysis provides a brief overview of how bioactive compounds (BC) impact meat and MP preservation, and how they can be utilized for preservation purposes. The use of BC, particularly plant-based antioxidants, can reduce the rate of auto-oxidation and microbial growth, thereby extending the shelf life of MP. These BC include polyphenols, flavonoids, tannins, terpenes, alkaloids, saponins, and coumarins, which have antioxidant and antimicrobial properties. Bioactive compounds can act as preservatives and improve the sensory and physicochemical properties of MP when added under appropriate conditions and concentrations. However, the inappropriate extraction, concentration, or addition of BC can also lead to undesired effects. Nonetheless, BC have not been associated with chronic-degenerative diseases and are considered safe for human consumption. MP auto-oxidation leads to the generation of reactive oxygen species, biogenic amines, malonaldehyde (MDA), and metmyoglobin oxidation products, which are detrimental to human health. The addition of BC at a concentration ranging from 0.025 to 2.5% (w/w in powdered or v/w in oil or liquid extracts) can act as a preservative, improving color, texture, and shelf life. The combination of BC with other techniques, such as encapsulation and the use of intelligent films, can further extend the shelf life of MP. In the future, it will be necessary to examine the phytochemical profile of plants that have been used in traditional medicine and cooking for generations to determine their feasibility in MP preservation

Biodiversity 2016. Status and Trends of Colombian Continental Biodiversity
This third volume of the annual report on biodiversity in Colombia continues the editorial line that begun in 2014. Using novel analytical and graphic proposals, these reports have the goal of communicating the contents to a broad public, making it available for discussion without sacrificing the quality of information. The challenge of communication continues to be a major part of the institutional project, and the new languages with which we are learning to communicate with society and other institutions are an experiment that we expect to be increasingly gratifying. The report for 2017 is already under construction and it counts on new digital technologies so the power of a colombian vital connection may be entirely expressed.
The included content evidences that we are still far away from having a systematic follow-up about most of the topics related to the management of biodiversity and ecosystem services, which is the only way to evaluate the effectiveness of policies and investments made by society. In fact, a limitation that is recognized is that of identifying positive or negative changes that affect different levels of organization of life on this planet; therefore, our global navigation route of the Aichi targets is still to be verified.
An additional purpose of this process includes the invitation of all Colombians to contribute in constructing and maintaining basic monitoring indicators for management since it is impossible to identify long-term trends of flora and fauna in the country without the support of institutions, researchers, and citizens. This challenge is immense in a megadiverse country such as Colombia. For this reason, the report will continue to open its pages to experts, and even indigenous peoples or local communities, for them to present their perspectives about environmental change and its effects on biodiversity in a systematic and documented manner. This has the objective of stimulating the commitment of everyone in the management of biodiversity and ecosystem services. The only way of overcoming the risk of extinction is through the active process of social learning in which all sectors assume a part of the complex responsibility in protecting the forms of life of the country, a roughly counted tenth of all creatures on Earth.
I thank all the people that contributed in this Report, those who have supported us in the phases of production, and all readers and users, who are the ultimate judges of its utility.Bogotá, D. C
