NUTRITIONAL STRATEGIES FOR ENHANCING GROWTH IN WEANED LAMBS: A CONCENTRATE STUDY
Christopher David Walker, Rachel Nicole Johnson, Marcus Anthony Thomas
The small ruminant livestock industry in Trinidad and Tobago faces significant challenges in terms of productivity, primarily attributed to poor reproductive strategies, limited genetic diversity, and inadequate veterinary support. However, the most critical factor affecting productivity is the suboptimal feed supply and feeding practices. The available feed resources, primarily natural pasture and crop residues, are characterized by their high fibrous content, substantial lignin levels, and overall low nutritive value. Animals consuming such low-quality feeds tend to utilize their fat reserves to meet nutritional needs, resulting in reduced body fat storage, particularly exacerbated during periods of forage scarcity. Livestock's live weight...
IMPROVING MUD CRAB (SCYLLA SERRATA) FATTENING EFFICIENCY THROUGH STRATEGIC DIETARY PROTEIN LEVELS FROM FISHERY BY-PRODUCTS
Nimal Perera, Ricardo Silva
Mud crabs, classified under the genus Scylla, are prominent crustaceans inhabiting the tropical Indo-West Pacific region, particularly in mangrove swamps and coastal habitats across South and Southeast Asia. Recognized for their sizable edible forms, they are commonly referred to as mangrove crabs. In Sri Lanka, they are locally known as "kalapu kakuluwa". Among the Scylla genus, Scylla serrata, Scylla tranquebarica, Scylla olivacea, and Scylla paramamosain are distinct species, with S. serrata being the most prevalent in the Asian-Pacific region. These crabs are esteemed for their delectable taste, distinctive texture, and rich nutritional profile. Their meat is a valuable source of...
EMPOWERING POTATO GROWTH: SLOW-RELEASE FERTILIZERS AND SOLANUM TUBEROSUM L. CV. GIGANT
Carlos Rodríguez Martínez, Ana María González Lópe
The advent of the nineteenth century brought about a shift in agricultural practices in Mexico, marked by the introduction of inorganic fertilizers alongside traditional methods like organic residues and green manures. This transition was catalyzed by the realization that relying solely on organic matter led to yields below 1.5 Mg ha-1. The turning point arrived in the 1950s with the onset of the Green Revolution, characterized by the adoption of improved seeds and a surge in the use of agrochemicals and inorganic fertilizers. This shift resulted in a remarkable doubling of the national average yield (Núñez, 2001). While the increased...
