Effect of Spirulina on Productive and Reproductive Traits as well as Hematological Parameters and the Meat Quality Characteristics in Local Omani Goats

Abstract

Spirulina platensis (SP) is a type of blue-green algae that has been extensively used as a dietary supplement for livestock in recent decades. It is a rich source of protein, vitamins, minerals, antioxidants, and essential amino acids, making it a highly nutritious feed supplement for animals. Additionally, SP is a good source of pigments such as phycocyanin and chlorophyll, which can be used as natural colourants in animal feed. The use of SP in livestock feed has several benefits, including improved growth, health of animals and a reduced environmental impact of animal agriculture due to its advantages regarding to haematological and biochemical parameters which play a major role in improving biological functions. Supplementation of SP in the diet of animals such as fish, poultry, pigs, and ruminants has been shown to have positive effects on growth performance, body confirmation, and meat quality. Additionally, SP supplementation can also improve animal welfare by reducing stress and disease. Despite the many benefits of SP as a feed supplement, there has been limited research on its effects on Omani goats under Omani conditions. This thesis aims to fill this gap by examining the effect of SP supplementation on the growth performance, body confirmation, meat quality, fatty acid profile, reproductive performance, and blood haematological and biochemical parameters of Omani goat bucks. The aim of this research was to gain a deeper understanding of the mechanisms behind the use of SP as a feed supplement for Omani goats and to provide valuable insights for future livestock management practices in Oman.
