The experiment was conducted using four hundred commercial day old (Vencobb) broiler chicks for 42 days. The experiment was designed to evaluate the effect of crude soy lecithin with or without lipase on performance, carcass traits and keeping quality of meat of broiler chickens. The birds were divided into four dietary treatments with four replicates of 25 birds each. The treatment groups comprised of A ( control-basal diet) without soy lecithin and Lipase while B basal diet with lipase, C Basal diet with 50% soy lecithin and D Basal diet with 50% soy lecithin and lipase. The data obtained were subjected to Analysis of variance in a completely randomized Design. The significant (P<0.01) influence of soy lecithin alone or in combination with lipase enzyme on cumulative weight gain, feed consumption and FCR was observed. The edible carcass yield percent was found significant (P<0.05) higher in lecithin alone or lipase enzyme supplemented groups. The higher livability was recorded in soy lecithin alone or in combination with lipase enzyme compared to control groups. The TBA values of broiler meat on 15 th day of storage showed significant (P<0.05) difference between the treatment groups. The findings concluded that dietary supplementation with soy lecithin alone and in combination with lipase enzyme influenced oxidative stability in breast and thigh muscle. Supplementation of crude soy lecithin alone or in combination with lipase enzyme enhanced the net profit per kg of live weight. It is concluded that the supplementation of soy lecithin alone or in combination with lipase enzyme through feed in broilers is beneficial for bird's performance, carcass traits, improved oxidative stability, and thereby increasing shelf life of meat during refrigerated storage and profitability.
An experiment was planned to explore the possibilities of replacement of concentrate mixture by Hedge lucerne (Desmanthus virgatus) in growing Osmanabadi goats for 90 days. Osmanabadi growing goats (18) of either sex with similar age and body weights (12.77±0.53 kg) were divided into two treatment groups and one control group (T0) with six goats in each group. Concentrate mixture was offered to control group (T0), while T1 and T2 groups received ration in which 50% and 100% concentrate was replaced by Hedge lucerne on dry matter basis. The mean fortnightly dry matter intake (g/d) was significantly higher in control (T0) and T2 than T1. The intake of DCP (g/d) was significantly higher in control and T1 as compared to T2. The per cent digestibility of nutrients namely DM, OM, CP, EE, CF and NFE did not differ significantly amongst the treatment groups. Total gain in body weight (kg) was significantly higher in T1 (2.71±0.13) as compared to T0 (2.58±0.50) and T2 (2.25±0.02). The final body weight of experimental goats were 15.57 kg (T0), 15.18 kg (T1) and 15.61 kg (T2) respectively. The body condition score was significantly higher in T0 and T1 than T2. The total cost of production was significantly higher in T0 (` 1858.86) followed by T1 (` 1810.81) and T2 (` 1725.85). The highest net profit per goat was recorded for T2 (` 2957.15), followed by T0 (` 2812.14) and T1 (` 2743.15) groups. It is concluded that inclusion up to 50% Hedge lucerne to replace concentrate in diet of goats improves growth performance and increases net profit of Osmanabadi goat production.
