Effect of Shrimp Meal Made of Heads of Black Tiger (<i>Penaeus monodon</i>) and White Leg (<i>Litopenaeus vannamei</i>) Shrimps on Growth Performance in Broilers

Abstract

The present study was conducted to measure the growth performance in growing broilers given shrimp meal (SM) made of heads of black tiger (Penaeus monodon) (BT) and white leg (Litopenaeus vannamei) (WL) shrimps. Forty-two male broiler chicks (8 days old, Ross 308) were randomly divided into 7 dietary groups (control, 5% BT, 10% BT, 15% BT, 5% WL, 10% WL and 15% WL) having similar body weight (6 birds per diet). Metabolisable energy and CP were adjusted to about 3, 180 kcal/kg and about 235 g/kg, respectively, and other nutrients were formulated to meet or slightly exceed the requirements. Diet and water were provided ad libitum during the experimental period (8 to 21 days old). The results revealed that body weight gain decreased in BT groups with increasing level of SM (P＜0.05), and feed intake decreased slightly with increasing level of SM in diets. As the result, feed conversion ratio also deteriorated with increasing level of SM. Similar trend was observed in WL groups, but the adverse effects of SM were milder comparing with BT groups. Nitrogen retention in both BT and WL groups tended to decrease with increasing level of SM. Chitin digestibilities in WL groups were greater than the corresponding values in BT groups. In conclusion, it is suggested that WL heads can be more nutritious SM for broiler diets than BT heads.

Effects of Formic Acid-Treated Shrimp Meal on Growth Performance and Nutrient Digestibility in Broilers

“…Similar findings are reported by Rahman and Koh (2016a). This trend was also observed in the TSM group, but was less prominent.…”

“…Rahman and Koh (2016a) reported similar findings, noting decreased growth performance for broilers that received diets containing more than 5% SM. These results suggest that decreased growth performance in the SM group may be, in part, due to decreased FI, and that SM contains one or more anorectic factors.…”

“…The maximum feed inclusion levels for shells and heads of black tiger shrimp (Penaeus monodon), and heads and white leg shrimp (Litopenaeus vannamei) were 4, 5, and 10%, respectively (Khempaka et al, 2006a;Rahman and Koh, 2016a). Some researchers have reported that these limited inclusion levels could be explained, in part, by the presence of chitin, which can decrease digestibility in broilers (Khempaka et al, 2006a) and rats (Oduguwa et al, 1998).…”

“…In general, the nutritional quality of shrimp meal (SM), as a protein source for chicken diets, is poor, although it depends on the species of shrimp and the body parts used ( Meyers, 1986 ; Ngoan et al , 2000 ; Rahman and Koh, 2014 ). The maximum feed inclusion levels for shells and heads of black tiger shrimp ( Penaeus monodon ), and heads and white leg shrimp ( Litopenaeus vannamei ) were 4, 5, and 10%, respectively ( Khempaka et al , 2006a ; Rahman and Koh, 2016a ). Some researchers have reported that these limited inclusion levels could be explained, in part, by the presence of chitin, which can decrease digestibility in broilers ( Khempaka et al , 2006a ) and rats ( Oduguwa et al , 1998 ).…”

Improvement in Nutritional Quality of Shrimp Meal with Autoclave and Chemical Treatments: an <i>in vitro </i>Study

“…The nutritional quality of shrimp meal (SM) has been investigated in our previous study to use this for an alternative protein source for broilers, and clarified that its nutritional quality was not good enough to be included more than 10% in a diet (Rahman and Koh, 2016), although SM quality was somewhat different depending on the portion and species (Rahman and Koh, 2014). Similar results have been reported in earlier studies (Fanimo et al, 1996;Gernat, 2001;Oduguwa et al, 2004;Khempaka et al, 2006a) where performances were decreased when chicken received diets containing more SM.…”
