Our results suggest that R2 (38%CP: 9% CL) is the most convenient feed for both species.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Effects of experimental diets with varying protein and lipid levels on weight gain (WG), specific growth rate (SGR), survival rate (SR), feed conversion rate (FCR), hepatosomatic and viscerosomatic indices (HSI and VSI) of two popular ornamental cichlid species, omnivorous (Pseudotropheus socolofi) and carnivorous (Haplochromis ahli) were studied for 56 days.
📊
Key Findings & Data:Two crude proteins (38%CP and 56%CP) and two crude lipids (9%CL and 16%CL) rates were applied to four formulated diets: R1 (38%CP:16%CL), R2 (38%CP:9%CL), R3 (56%CP:16%CL) and R4 (56%CP:9%CL).

Abstract

Effects of experimental diets with varying protein and lipid levels on weight gain (WG), specific growth rate (SGR), survival rate (SR), feed conversion rate (FCR), hepatosomatic and viscerosomatic indices (HSI and VSI) of two popular ornamental cichlid species, omnivorous (Pseudotropheus socolofi) and carnivorous (Haplochromis ahli) were studied for 56 days. Two crude proteins (38%CP and 56%CP) and two crude lipids (9%CL and 16%CL) rates were applied to four formulated diets: R1 (38%CP:16%CL), R2 (38%CP:9%CL), R3 (56%CP:16%CL) and R4 (56%CP:9%CL). The SR was 100% in H. ahli while that of P. socolofi ranged from 66.6% to 93.3% in the two groups, respectively. The highest WG and SGR were seen in the H. ahli and P. socolofi groups fed with R2 feed. The best FCR values were obtained in R2 groups of H. ahli (1.64) and R3 groups of P. socolofi (1.41). HSI values for H. ahli and P. socolofi were 2.73±0.29 to 3.25±0.34 and 3.30±0.19 to 4.02±0.09 respectively, while VSI values were 10.48±0.81 to 10.50±1.57 and 13.28±0.61 to 15.41±0.69, respectively. No significant differences were observed for HSI and VSI of H. ahli and P. socolofi (P>0.05). Our results suggest that R2 (38%CP: 9% CL) is the most convenient feed for both species.

Özet

Popüler süs balıklarından omnivor (Pseudotropheus socolofi) ve karnivor (Haplochromis ahli) beslenme özelliği gösteren iki farklı çiklit türünün 56 gün süreyle protein ve yağ oranları farklı deneme yemleri ile beslenmesinin ağırlık artışı, spesifik büyüme oranı (SBO), yaşama oranı, yem değerlendirme oranı (YDO), hepatosomatik indeks (HSI) ve viscerosomatic indeks (VSI) değerleri üzerine etkileri araştırılmıştır. İki farklı ham protein (%38 ve %56 HP) ve ham yağ oranı (%9 ve %16 HY) kullanılarak R1 (%38 HP:%16 HY), R2(%38HP:%9 HY), R3 (%56HP:%16HY) ve R4 (%56HP:%9HY) olmak üzere dört farklı yem hazırlanmıştır. Bu yemlerle deneme balıkları günde üç kez doyana kadar elle beslenmiştir. Deneme sonunda yaşama oranı tüm gruplarda H. ahli için %100 olurken, P. socolofi için %66,6-93,3 arasında değişiklik göstermiştir. H. ahli ve P. socolofi gruplarında en yüksek canlı ağırlık artışı ve en iyi SBO değerleri R2 yemi ile beslenen gruplarda görülmüştür. En iyi YDO değeri ise H. ahli (1,64) için R2 ve P. socolofi (1,41) için R3 yemi ile beslenen gruplarda saptanmıştır. H. ahli ve P. socolofinin HSI değerleri sırasıyla 2,73±0,29-3,25±0,34 ve 3,30±0,19-4,02±0,09, VSI değerleri ise 10,48±0,81-10,50±1,57 ve 13,28±0,61-15,41±0,69 arasında belirlenmiş olup, gruplar arasındaki farklılık önemsiz bulunmuştur (P>0,05). Yapılan çalışmaya göre R2 (%38 HP ve %9 HY) yeminin her iki tür için en uygun yem olduğu saptanmıştır.
