“…Also, lysine and threonine are generally considered to be the limiting amino acid of RSM, frequently causing reduced growth of animals (Babatunde et al . ; Bahadur, Haldar & Ghosh ). Thus, lysine, threonine and leucine deficiency may be one of the reasons responses for the poorer feed utilization of tilapia fed diet with high inclusion level (>300 g kg −1 ) of RSM.…”

A feeding trial was conducted to evaluate the effects of replacing soybean meal (SBM) with rubber seed meal (RSM) on digestive enzyme activity, nutrient digestibility and retention in juvenile tilapia (Oreochromis niloticus 9 Oreochromis aureus). Five isonitrogenous and isoenergetic diets were formulated with 0 (control), 100, 200, 300 and 400 g kg À1 RSM replacing graded levels of SBM respectively. Each diet was randomly assigned to triplicate groups of 30 fish (initial average weight 5.2 g) per aquarium in a rearing system maintained at 29 AE 1°C for 8 weeks. The hepatic protease and lipase activities gradually decreased with increasing dietary RSM level, but no significant differences were observed among the low inclusion level (0-200 g kg À1 ) groups. The apparent digestibility coefficients of dry matter, crude protein, crude lipid and ash showed a similar trend as the hepatic protease and lipase activities. The retentions of protein and individual essential amino acid (except lysine, threonine and leucine) in fish fed diet with 200 g kg À1 RSM were similar to those in fish fed the control diet. These results indicate that dietary RSM inclusion level up to 200 g kg À1 did not markedly affect the digestive enzyme activity, nutrient digestibility and retention in tilapia, whereas these were depressed by the inclusion of 400 g kg À1 RSM.

“…Sharma et al (2018) reported that weight gain and breast yield percentage increased while FCR improved by Lys supplementation. L-Lys sulfate performed better than L-Lys HCl in commercial diets (Bahadur et al, 2010). The comparison between Lys HCl and Lys sulfate was performed in pigs and fish but there was limited experimental study on bio efficacy of Lys sources in broilers (Wang et al, 2007).…”

The objective of this study was study the protein bound and free lysine (Lys) on production performance in broilers. Two hundred and sixteen (216) day-old broiler chicks were distributed into three treatments, six replicates and 12 birds in each. Three isonitrogenous (CP 22.5%) and isocaloric (ME 3000 Kcal/kg) experimental diets were formulated. In control diet, total digestible Lys (1.20%) was contributed by feed ingredients like soybean meal, canola meal and fish meal. In other two diets, out of 1.2, 0.06 was free Lys that was either contributed by L-Lys Sulfate or L-Lys HCl which were assumed to be 100% digestible. Feed intake was (P≤0.05) lower in birds received free Lys than those reared on bounded Lys. Weight gain and FCR were improved (P≤0.05) in birds received protein bound Lys and free Lys as L-Lys Sulfate than L-Lys HCl. Dressing percentage, liver weight, water holding capacity, pH, cooking loss and blood hematology parameters were not affected by treatments. Production cost per kg live weight was lower in birds received free Lys as L-Lys Sulfate than others treatments. It can be concluded that use of free Lys in the form of L-Lys Sulfate had improved feed efficiency and economics efficiency without having negative effect on meat quality and blood hematology parameters.

RESUMENObjetivo. Evaluar el efecto de la harina de pijiguao y lisina sintética sobre los lípidossanguíneos de cerdos en crecimiento y engorde. Materiales y métodos. El estudio serealizó en dos etapas. En la primera etapa se utilizaron 72 cerdos castrados en crecimientode 30 ± 0.5 kg, en un arreglo factorial 2x3: dos niveles de lisina sintética (0 y 2.70 g/kg)y tres niveles de harina de pijiguao (0, 160 y 320 g/kg). En la segunda etapa se utilizaron16 cerdos en engorde de 67.25 ± 1.17 kg, en un arreglo factorial 2x2: dos niveles de lisinasintética (0 y 2.70 g/kg) y dos niveles de pijiguao (0 y 175 g/kg). Se determinaron lasconcentraciones séricas de triacilgliceroles, colesterol total y ácidos grasos. Resultados.Los cerdos en crecimiento que consumieron pijiguao presentaron menores (p<0.001)concentraciones de colesterol que el grupo control (2.27 y 2.23 mmol/l vs 2.56 mmol/l) ytriacilgliceroles (0.34 y 0.28 mmol/l vs 0.42 mmol/l). El ácido oleico incrementó (p<0.01)con el mayor nivel de pijiguao (20.78% a 28.84%), y la lisina aumentó (p<0.05) el ácidolinoleico (27.83% a 31.29%). Los cerdos alimentados con pijiguao y lisina mostraronmenor (p<0.001) ácido palmítico que el grupo con pijiguao sin lisina (0.23 y 0.19% vs0.45 y 0.62%, respectivamente). En la etapa de engorde los triacilgliceroles disminuyeron(p<0.05) en los cerdos alimentados con pijiguao y lisina (0.46 a 0.36 mmol/l). Los cerdosalimentados con pijiguao mostraron menor ácido linoleico y mayor ácido oleico (p<0.001).Conclusiones. Las dietas con pijiguao y lisina sintética no causaron efectos negativossobre los lípidos sanguíneos de cerdos.
