Effect of the Inclusion of Extruded Flaxseed in the Diet of Fattening Pigs on Performance Parameters and Blood Parameters

Abstract

The aim of the study was to determine the effect of the inclusion of 2%, 4% and 6% extruded flaxseed in the diet of fattening pigs on their growth performance parameters, carcass parameters, and selected blood parameters. The experiment was conducted on 160 weaners (from about 30 kg to about 110 kg BW) assigned to four experimental groups of 40 animals each (5 replicates with 8 individuals each). The animals in control group received a diet in which the source of fat was soybean oil. The other groups received extruded flaxseed (FE) in place of soybean meal in the amount of 2% (group 2FE); 4% (group 4FE) and 6% (group 6FE). Soybean oil was added to the diets in the experimental treatments to obtain equal amounts of fat. The inclusion of 2% and 4% extruded flaxseed in the diet of fatteners in place of soybean meal significantly improved the digestibility of basic nutrients, i.e. ether extract (by about 5%) and dietary fibre (by more than 20%) and led to better growth performance (higher BW by about 11%; higher ADG by about 20% and lower FCR by about 12%) vs group C. In the groups with 2% and 4% extruded flaxseed there was also an increase in the lean meat content of the carcasses (by about 6%) and the thickness of the backfat (by about 6.5%) vs group C. The inclusion of extruded flaxseed did not affect the animals' condition, as indicated by the haematological and biochemical parameters of the blood, which were within reference ranges. The results for production, nutrient digestibility and carcass analysis between groups 2FE and 4FE were similar, and at this stage of research indicate that the use of 2% extruded flaxseed is economically more justified.

Synergetic Influence of Some Tropical Leaf Meals and Garlic on the Haemato-biochemical Parameters and Antioxidant Activities of Weaner Pigs

“…The result of this study shows that the levels of CAT in the pigs increase with increasing levels of composite leaf meals. The value obtained in pigs fed 20g/kg GCLM coincide with the result of [35,36]. Garliccomposite leaf meals such as garlic, scent leaves, neem leaves, bitter leaves and Moringa leaves are rich in catalase, including garliccomposite leaf meals in pig diets also stimulate production of catalase which might be one of the reasons for higher catalase, but did not correspond with the findings of [37] who obtained higher CAT values in weaner pigs fed with Broussonetia papyrifera leaf extract.…”

Effect of the inclusion of extruded flaxseed in the diet of fattening pigs on lipid metabolism and tissue redox status

“…The mineral and vitamin premix contained (in 1 kg) vitamin A 600,000 IU, vitamin D 3 60,000 IU, vitamin E 3,000 mg, vitamin K 3 120 mg, vitamin B 1 120 mg, vitamin B 2 240 mg, vitamin B 6 240 mg, nicotinic acid 1,600 mg, pantothenic acid 800 mg, folic acid 160 mg, biotin 10 mg, vitamin B 12 1.6 mg, choline chloride 12 g, Mg 0.8 g, Fe 6 g, Zn 5.6 g, Mn 2.4 g, Cu 6.4 g, J 40 mg, Se 16 mg, and Co 16 mg. The exact ingredient composition and chemical composition of the diet have been published in a paper by Klimiuk et al 46 .…”

Enhancing nutrient digestibility and antioxidant efficacy in piglets: The impact of fermented rapeseed meal supplementation on biochemical parameters and oxidative stress markers

“…For the analysis, n = 6 randomly selected animals from each group were randomly selected, separated, and were fed the marked feed. Feces were collected seven days before slaughter in the morning hours (6-9 AM) from each pig for the analysis of the digestibility indices of basic nutrients (Klimiuk et al, 2023). Fecal samples were collected over five consecutive days and stored in a refrigerator.…”
