Effect of Graded Levels of Spirulina (Arthropsira platensis) on Feed Intake and in vivo Digestibility of Trypsacum laxum in Guinea Pig (Cavia Porcellus L)

Abstract

The intake and in vivo digestibility of Trypsacumlaxum in guinea pigs according to the graded level of spirulina was evaluated in Cameroon. 20 animals aged of 6 months with an average weight of 450 ± 50 g were randomly divided into 4 equivalent groups. Each group received T. laxum and 40g of compound feed containing 0% (TS0), 2% (TS2), 4% (TS4), and 6% (TS6) of spirulina. Feed intake was the different between the left over and the quantity served. The sample of T. laxum and those of each diet as well as feces were collected and analyzed for the apparent digestibility of each nutrient. Animals were weighed at the beginning and at the end of each period of the test to determine the body weight gain. This study showed that the average daily intake of dry matter (DM) for TS0, TS2, TS4 and TS6 was 74.39 ± 2.98, 78.66 ± 3.14, 83.89 ± 4.28 and 77.76 ± 4.40 g/head/day. The highest apparent digestibility coefficients of different nutrients were obtained with animals fed TS6 group while the lowest were observed in TS0.The apparent digestibility coefficient of dry matter (DM), organic matter (OM) and crude protein (CP) of the supplemented group were statistically higher than those of the control diet. Animals’ weight performances were statistically comparable between treatments. Thus, the combination of T. laxum with concentrated feed containing spirulina can be recommended for guinea-pigs, but the level of incorporation may not exceed 4% of its daily ration.

Effect of Inclusion of Arthrospira maxima Microalgae in Laying Hen Diets on Production Parameters and Egg Characteristics

“…This behavior has not been reported in other literature for laying hens, however, as mentioned before, there are no other trials with such a high level of inclusion as 6%, as in the present study. Nguedia et al (2019) reported a decrease of 6.13 g/animal/day in dry matter intake for guinea pigs supplemented with 6% Arthrospira maxima compared to supplementation at 4%. However, the lower feed intake did not result in a change in feed conversion ratio (FCR).…”

Effect of Two Pepper Powders (Piper nigrum and Piper guineense) as A Feed Additive in The Ration on Intake and In vivo Digestibility in cavies (Cavia porcellus L.)

“…Cavy farming is widely practiced in Cameroon, especially in low-income families where it constitutes an important source of protein (Noumbissi et al, 2014). In village farming, these animals feed on kitchen waste and harvest residues, which o en have de ciencies in essential nutrients, resulting in low production and early mortality (Nguedia et al, 2019). However, its optimal utilization as a protein source requires e cient feeding to improve productivity (Zougou et al, 2017).…”
