“…The ileal digestibility of most AA was lower for the ARG than for the USA and BRA meáis but no significant differences on TÍA content ofthe meáis were observed among origins. Moreover in the current experiment, the TÍA ofthe SBM was positively correlated with the CSID of CP, Lys and Cys, an observation which contrasts with most published reports which correlate the TÍA content of the meal with reduced AA digestibility both in pigs (Qin et al, 1996;Valencia et al, 2008a,b) and poultry (Leeson and Atteh, 1996;Wiseman et al, 2003;Valencia et al, 2009b). Temperature, pressure and time applied during the processing ofthe beans denature the structure ofthe protein fraction and inactivate most ofthe heat-labile antinutritional factors presents in the meal (Marsman et al, 1997;Batal et al, 2000).…”

The correlations between chemical composition and coefficient of standardized ileal digestibility (CSID) of crude protein (CP) and amino acids (AA) were determined in 22 soybean meal (SBM) samples originated from USA (n = 8), Brazil (BRA; n = l) and Argentina (ARG; n = l) in 21-day oíd broilers. Birds were fed a commercial maize-SBM diet from 1 to 17 days of age followed by the experimental diets in which the SBM tested was the only source of protein (205g CP/kg) for three days. Also, in vitro nitrogen (N) digestión study was conducted with these samples using the two-step enzymatic method. The coefficient of apparent ileal digestibility (CAID) of the SBM, independent of the origin, varied from 0.820 to 0.880 for CP, 0.850 to 0.905 for lysine (Lys), 0.859 to 0.907 for methionine (Met) and 0.664 to 0.750 for cysteine (Cys). The corresponding CSID valúes varied from 0.850 to 0.966 for CP, 0.891 to 0.940 for Lys, 0.931 to 0.970 for Met and 0.786 to 0.855 for Cys. The CSID of CP and Lys of the SBM were positively correlated with CP (r = 0.514; P<0.05 and r=0.370; P = 0.09, respectively), KOH solubility (KOH sol.) (r=0.696; P<0.001 and r = 0.619; P < 0.01, respectively), trypsin inhibitor activity (TÍA) (r = 0.541; P < 0.01 and r=0.416; P = 0.05, respectively) and reactive Lys (r=0.563; P<0.01 and r=0.486; P<0.05) valúes, but no relation was observed with neutral detergent fiber and oligosaccharide contení. No relation between the CSID of CP determined in vivo and N digestibility determined in vitro was found. The CSID of most key AA were higher for the USA and the BRA meáis than for the ARG meáis. For Lys, the CSID was 0.921,0.919 and 0.908 (P< 0.05) and for Cys 0.828, 0.833 and 0.800 (P< 0.01) for USA, BRA and ARG meáis, respectively. It is concluded that under the conditions of this experiment, the CSID of CP and Lys increased with CP content, KOH sol., TÍA and reactive Lys valúes of the SBM. The CSID of most limiting AA, including Lys and Cys, were higher for USA and BRA meáis than for ARG meáis.

“…However, it has been postulated that insect larval meals could be used in poultry feeding to replace protein sources such as soybean meal (Ramos-Elorduy et al, 2002;Veldkamp et al, 2012;Makkar et al, 2014). In this sense, the average AIDC of the indispensable AAs in TM coincides with the findings of Valencia et al (2009), Ravindran et al (2005) and Huang et al (2006) in 21, 42 and 49 day old broilers, respectively. It is worth noting that both the concentration and the AIDC of lysine in the TM meal were similar to that of the soybean meal analyzed in the above studies (Ravindran et al, 2005;Huang et al, 2006Huang et al, , 2007, although the AIDC for methionine was lower in the TM meal than in the soybean meal.…”

“…Feed intake is a critical factor determining broilers performance especially body weight gain with the compensatory growth (Lilburn, 1998and Yang et al, 2009. Thus enhanced feed consumption achieved through any feeding program particularly focused on early nutrition can maximize birds growth (Henderson et al, 2008 andValencia et al, 2009). The best feed conversion (1.88) was observed by the birds fed on green feed color but it was medium in body weight during sixth week.…”

A total number of 120-one day old chicks were randomly assigned into four equal groups to investigate the effect of feed color on their growth performance and carcass characteristics. The first group was fed non color feed and considered as a control group (C). While, second, third and fourth treatment groups (T1, T2 and T3) were fed green, orange or red feed, respectively. The obtained results showed that feeding colored diets had significant positive effect on body weight, body weight gain, feed consumption and feed conversation throughout the experimental period. Also, there were significant differences in carcass color, dressed carcass percentages, carcass cut-up parts (breast and drum percentages) or muscles (breast), gizzard, carcass deep (cm) and abdominal fat percentages. However, no significant differences (P>0.05) existed in most giblets (heart and liver percentages) and thigh percentages. It could be concluded, that birds fed orange feed had the best performance. Consequently, feed color for broiler chicks should be in orange color.
