ABSTRACT

The present research was conducted to investigate the effect of various levels of fenugreek seeds supplementation on feed intake, egg production and egg quality of Rhode Island Red spent layers. A total of 60 spent Rhode Island Red layers were assigned to 4 treatments; FS-0, FS-0.5, FS-0.75, and FS-1 with 3 replicates, each with 5 birds. Birds were kept in cages for 28 days in open sided house. FS-0 was kept as control while treatments FS-0.5, FS-0.75 and FS-1 were provided with fenugreek seed powder in the ration at the rate of 0.5, 0.75 and 1%, respectively. Egg production and feed intake was recorded on daily basis. Egg weight, egg shell weight, egg shell thickness, Haugh unit, albumin height and yolk weight were determined on weekly basis. The results showed that FS supplementation significantly (P<0.05) decreased feed intake (g/hen/day) at all recorded stages. Overall higher feed intake was noted for the control treatment while lower feed intake was noticed for treatment FS-1. Significantly higher (P<0.05) egg production was recorded for treatment FS-0.5 followed by treatment FS-0.75 while lower egg production was recorded for the control and FS-1 treatments. Egg quality traits including egg shell weight, egg weight, egg shell thickness, Haugh unit, albumin height and yolk weight were not affected by supplementation of fenugreek seeds. It was concluded from the study that supplementation of fenugreek at the rate of 0.5% increased egg production without affecting egg quality traits.

Introduction

Egg production and quality depend on nutritional management and health of laying birds (Shahid et al., 2015; Raza et al., 2016; Chand et al., 2018). To enhance the productivity under normal and adverse conditions, different medicinal plants have been used in animals and birds (Khan et al., 2012a, b; Alzawqari et al., 2016). Medicinal plants are widely used due to easy availability, effective antimicrobial nature, reduced cost, affordability of a common farmer, decreased disease associated risk and better growth and productive performance (Khan et al., 2012c, d; Chand et al., 2014; Tanweer et al., 2014; Alhidary et al., 2017). In order to increase the effectiveness of herbal products and herbs are included in the diets of birds and animals instead of antibiotics and chemical products (Abudabos et al., 2016; Zia ur Rehman et al., 2018). Herbs and their active constituents improve digestion, body metabolism and have bactericidal action (Abudabos et al., 2018).

Fenugreek (Trigonella foenum graecum) belongs to the family Leguminosea (Alarcon-Aguilara et al., 1998). The protein level in fenugreek is 20-30%. It has 5-10% fatty acids, which mostly include palmitic, oleic, linolenic and linoleic acids. Fenugreek has 45-65% total carbohydrates, which represent galactomannan by 15%. Fenugreek is also rich in calcium, manganese, phosphorous, zinc, iron, saponins and flavonoids. Seeds of fenugreek have unique chemical composition; protein (28.4%), crude fiber (9.3%) and crude fat (7.1%) (El Nazar and El Tinay, 2007). Fenugreek also contains iron, para-amino benzoic acid (PABA), phosphates, lecithin, B-complex and choline that aid in disintegration of fatty substances and cholesterol (Dixit et al., 2005). Seeds and leaves of fenugreek are used widely for the preparation of powders and extracts for medicinal uses (Basch et al., 2003). Seeds of fenugreek at the level of 0.05% have been reported to improve feed conversion in layers (Moustafa, 2006) and increased egg production by 2.23% and reduced feed intake were also reported at the level of 0.5% (Abaza, 2007).

Keeping in view the potential advantages of using seeds of Fenugreek in poultry sector, the effect of Fenugreek seeds on egg production and egg quality in layers need to be explored. Therefore, the present study was planned to elucidate the effects of different dietary supplementations of Fenugreek seeds on egg quality and production performance of Rhode Island Red spent layers.

 

Materials and methods

Experimental animals, design and management

In the study, a total of 60 Rhode Island Red (RIR) spent layers were selected and distributed randomly among 4 treatments, each with 15 birds and 3 replicates. The treatments were denoted with FS-0, FS-0.5, FS-75 and FS-1 and are represented with 4 levels as 0, 0.50, 0.75 and 1%, respectively. A 16 h day light was given to the birds throughout experimental period. The birds were kept in cages, in open sided house under similar environmental conditions and fed with basal diet. Birds were offered water ad libitum. The study was continued for four weeks including first week for adaptation period.

Feed intake and egg production

On daily basis feed intake was recorded by subtracting refused feed from feed offered. On daily basis eggs were collected from each replicate and daily egg production was calculated to work out total egg production.

Egg quality traits

Five eggs from each replicate (15 eggs from each treatment group) were collected randomly at the end of each week to measure the following egg quality traits. For egg weight, eggs were weighed on electric balance. With the help of standard screw gauge, shell thickness was measured after removing shell membrane. Shell thickness was measured at 3 different locations on the same egg. Yolk was weighed on electrical balance by pouring it in Petri dish. With the help of Spherometer, albumin height was calculated. After removing the egg contents, the inside of the shell was dried with the help of tissue paper and then shell was weighed on electrical balance. To measure Haugh unit, egg sample was broken in petri dish and Haugh unit was measured by using the following formula of Silversides et al. (1993).

HU=100 x log (h+7.57 – 1.7w0.37)

Where, h is albumin height (cm) and w is weight of egg (g).

Statistical analysis

The statistical analysis was performed in SAS 9.2 (SAS Institute, 2009) using a completely randomized design and least significant difference (LSD) was used for statistical difference among various experimental treatments. Data were analyzed by one-way ANOVA. Duncan multiple range tests were used to compare means. Significance was declared at P < 0.05.

 

Results and discussion

Feed intake data of spent layers supplemented with various levels of fenugreek seeds is presented in Table I. There was significantly decreasing effect of various levels of fenugreek seeds on feed intake of experimental birds. Feed intake during 1st week was significantly higher for the control treatment followed by FS-0.5 and FS-0.75 while lowest feed intake was noted for treatment FS-1. The same trend was observed during 2nd, 3rd, and 4th week.

Decreased feed intake with treatment in the present study might be due to the reason that seeds of Fenugreek have antinutritional factor (Hooda and Jood, 2002). Our findings are in line with the results of Awadein et al. (2010) who mentioned that average intake of feed of Manadrah hen fed diet containing 0.5% fenugreek seeds was significantly lower than the control. Abaza (2007) also

reported significant decrease in feed intake by supplementation of fenugreek seeds in the ration of layers. In contrast to the present study, Moustafa (2006) reported no significant effect on feed intake by supplementation of fenugreek at the level of 0.5% as compared to the control.

Egg production (%) (hen/day) at different weeks of experiment is given in Table II. Results showed significant (P<0.05) effect of various levels of fenugreek seeds on egg production. Significantly increased egg production was observed during 2nd week with treatment FS-0.5, followed by group FS-0.75 and FS-0, while lower egg production was reported with FS-1. An increasing level of FS resulted reduction in egg production. After 2nd week, egg production was significantly decreased (Table II). The high percentage of egg production in group FS-0.5 may be due to phytoestrogen which may have stimulatory effect on egg production (Awadein et al., 2010) while lower egg production in high levels of fenugreek supplemented groups may be due to reduced feed intake in these groups (Assefa, 2014).

Our findings are in line with Awadein et al. (2010) found significant increase in egg production of layers supplemented with 0.1 and 0.5% fenugreek. Contrary to the results of the present study, Abaza (2007) reported that supplementation of fenugreek seed at the rate of 0.5% has no effect on egg production. Similarly, Safaa (2007) reported that addition of 2% fenugreek has no effect on egg rate.

Results on egg quality parameters of spent RIR layers fed with diet supplemented with various levels of Fenugreek seed is presented in Table III. Fenugreek seeds supplementation had no significant effect on egg quality parameters of spent layers. Different treatments showed variable results for different egg quality parameters. Numerically higher level of egg weight was recorded with treatment FS-0.75, followed by treatment FS-1, while lower egg weight was recorded for control and treatment FS-0.5. There was numerically increase in egg shell thickness with FS-1 while it decreased with FS-0.5. Numerically, egg shell weight was higher with treatment FS-0.5, followed by FS-0.75 and FS-1 while lower egg shell weight was recorded with control treatment. Egg yolk weight was not affected by treatments, however numerically higher value of yolk weight was recorded with treatment FS-0.75, while lowest egg yolk weight was recorded with control group. Similarly, supplementation of Fenugreek seed did not present any significant influence on albumin height and Haugh unit. Egg quality parameters were not improved significantly with various levels of fenugreek seeds in the diet of experimental birds. Among different treatments numerically slight differences were observed. Our results are in accordance with Abaza (2007) who found no significant effect on egg quality traits of laying hen supplemented with 0.5% fenugreek. Safaa (2007) observed no significant effect in egg quality by the addition of 2% fenugreek. Awadein et al. (2010) reported that supplementation of fenugreek at level of 0.1% and 0.5% in the ration of laying hen had no influence on egg shell weight, egg weight, but egg shell thickness, yolk weight, and Haught unit were significantly increased.

 

Conclusion

The results of the present study revealed that fenugreek seeds supplementation at the rate of 0.5% decreased feed intake and improved egg production of spent layers by 10% without affecting egg quality traits.
