“…On the other hand, the negative control group (6) had no vitamin-mineral premix or Spirulina in the diet. As a result, the dietary Spirulina group shows a higher significant difference (p<0.05) from the negative control group in the live weight of broilers [16]. The other groups of birds 1, 2, 3 and 4 had no significant differences (p>0.05) among them.…”

“…Best feed conversion ratio was observed in group 6 (1.99) compared to control (1.72), group 2 (1.65), group 3 (1.69), group 4 (1.61) and group 5 (1.62). As mentioned above, the feed conversion ratio is related to feed intake and live weight gain in all groups of birds [16]. In group 1, 2, 3, 4 and 5, birds received the proper nutrients available in their diet.…”

“…Moreover, the broiler is a very popular poultry item in Bangladesh [11][12][13] and other countries which supplied a major portion of meat demand. The villagers of Bangladesh are rearing broiler by establishing the small firm of the home yard [14,15] and earn money which helps to alleviate poverty [15][16][17][18] and ensuring food security [18][19][20]. Many people of the remote village take broiler poultry farming as a profession [2].…”

The main purpose of this study was to explore the effects of Spirulina (Spirulina platensis) as a feed supplement by replacing Vitamin-Mineral Premix on the performance of broiler. The study explored that final body weight was 1039, 1070, 1044, 1065, 1117 and 893 g/bird in group 1, 2, 3, 4, 5 and 6 where significantly (p<0.5) higher weight observed in Spirulina group (5) but lower in negative control group (6). Feed intake observed more or less similar in all groups (1483±24g; p>0.5). Feed conversion ratio (kg FI/kg LWG) observed significantly different like 1.72, 1.65, 1.69, 1.62, 1.61 and 1.99 in group 1, 2, 3, 4, 5 and 6 respectively (p<0.5) where higher in negative group (6) and control group (1), but is lowest and similar in 75% Spirulina group (4) and highest (100%) Spirulina group (5). %Ash of different dietary groups were 46.35, 46.54, 48.93, 49.93, 55.07 and 46.92 of group 1, 2, 3, 4, 5 and 6 respectively. The %ash of bone was gradually increased among dietary groups and the best result was obtained in 100% Spirulina group 5 (55.07). It also revealed that diets containing no vitamin-mineral premix with 100% Spirulina improve the performance of broiler. The findings suggest that poultry farmer can use spirulina as a feed item for broiler for more yield.

“…From this pool, all abstracts were examined and studies reporting the effect of either diets or production systems on meat fatty acid profiles were shortlisted. Papers focused solely on novel and unconventional feeding strategies such as inclusion of tannins (Morales & Ungerfeld, 2015) or microalgae (Madeira et al., 2017) were excluded. Furthermore, selection was limited to beef, lamb, chicken, and pork—the four most commonly produced meats globally (OECD/FAO, 2017)—and therefore work on other meat (e.g., rabbit) was also excluded.…”

Framework for life cycle assessment of livestock production systems to account for the nutritional quality of final products

Life cycle assessment (LCA) is widely regarded as a useful tool for comparing the environmental impacts of multiple livestock production systems. While LCA results are typically communicated in the form of environmental burdens per mass unit of the end product, it is increasingly becoming recognized that the product quality also needs to be accounted for to truly understand the value of a farming system to society. To date, a number of studies have examined environmental consequences of different food consumption patterns at the diet level; however, few have addressed nutritional variations of a single commodity attributable to production systems, leaving limited insight into how on‐farm practices can be improved to better balance environment and human nutrition. Using data from seven livestock production systems encompassing cattle, sheep, pigs, and poultry, this paper proposes a novel framework to incorporate nutritional value of meat products into livestock LCA. The results of quantitative case studies demonstrate that relative emissions intensities associated with different systems can be dramatically altered when the nutrient content of meat replaces the mass of meat as the functional unit, with cattle systems outperforming pig and poultry systems in some cases. This finding suggests that the performance of livestock systems should be evaluated under a whole supply chain approach, whereby end products originating from different farm management strategies are treated as competing but separate commodities.

“…In turn, bead milling is a successfully, rising process in the food industry used to incorporate microalga cells as food additives. This aspect is particularly relevant if microalgae are included at higher percentages in the diet, that is used as feed ingredient not as feed supplement (Madeira et al, 2017). Therefore, it is imperative to find novel technologies, cheaper and under a strictly controlled process, to disrupt A. platensis cells to improve microalgal nutrient utilization, as proteins and lipids by monogastric animals (Austic, Mustafa, Jung, Gatrell, & Lei, 2013;Lum et al, 2013).…”

The main goal of this study was to test a rational combination of pre-selected carbohydrate-active enzymes (CAZymes) and sulphatases, individually or in combination, in order to evaluate its capacity to disrupt Arthrospira platensis cell wall, allowing the release of its valuable nutritional bioactive compounds. By the end, a two-enzyme constituted mixture (Mix), composed by a lysozyme and a α-amylase, was incubated with A. platensis suspension. The microalga cell wall disruption was evaluated through the amount of reducing sugars released from the cell wall complemented with the oligosaccharide profile by HPLC. An increase of the amount of reducing sugars up to 2.42 g/L in microalgae treated with the Mix relative to no treatment (p < .05), as well as a 7-fold increase of oligosaccharides amount (p < .001), were obtained. With resort of fluorescence microscopy, a 36% reduction of fluorescence intensity (p < .001) was observed using Calcofluor White staining. In the supernatant, the Mix caused a 1.34-fold increase in protein content (p = .018) relative to the control. Similarly, n-6 polyunsaturated fatty acids (PUFA) (p = .007), in particular 18:2n-6 (p = .016), monounsaturated fatty acids (MUFA) (p = .049) and chlorophyll a (p = .025) contents were higher in the supernatant of microalgae treated with the enzyme mixture in relation to the control. Taken together, these results point towards the disclosure of a novel two-enzyme mixture able to partial degrade A. platensis cell wall, improving its nutrients bioavailability for monogastric diets with the cost-effective advantage use of microalgae in animal feed industry.
