Title

Effect of tomato pomace on performance, quality parameters and malondialdehyde levels in quail chicks

Pages

Abstract

 Introduction: Use of alternative feed ingredients such as tomato (Lycopersicon esculentum) pomace for poultry diets is an important factor of successful poultry production in many parts of the world (Bezabih Yitbarek, 2013). Commercial processing of tomato (juice, paste, puree, soups and/or ketchup preparations) produces a large amount of pomace with high nutritional value. Up to 30% of the tomato, by weight, is wasted in the industry as pomace. tomato pomace as an inexpensive and primary by-product of tomato manufacturing have been successfully used for poultry nutrition worldwide. This fiber rich byproduct is a good source of protein, pigment, and vitamins (B and E). The composition of tomato pomace varies according to agricultural and processing practices, the degree of drying, moisture removal and separation of cellulose. tomato pomace is used as an additive in livestock feed since ruminants such as cattle and dairy cow can digest fiber. Pamce is also used for nutrition of laying and breeder birds. Materials and methods: This study was carried out to evaluate the effects of tomato pomace in breeder quails on performance, weight of organs, quality of newly hatched chicks and the amount of malondialdehyde in meat of progeny. A total of 160 Japanese quail were allocated in a completely randomized design to four treatments of 0. 0 (control treatment without tomato pomace), 4, 8 and 12% tomato pomace for five weeks. Each treatment had four replicates (including two males and eight females in each replicate). The diets of breeders and the growing quails was formulated acocording the nutrient requirements of quils (NRC, 1994). tomato pomace was only fed to quail breeder. Before the experiment, the nutrients contents of both corn and soybean meal were analyzed by near infrared spectroscopy (NIR). The birds had free acess to feed and water during the breeder and growing periods. A lighting schedule of 16L: 8D and 23L: 1D was imposed respectively during the breeder and growing periods. Twenty-five fertile eggs from each replicate (100 eggs from each treatment) were collected for hatchery in the 5 th week of breeder feeding program. The experimental protocol was approved by animal care and committee of the Urmia University. Ten newly hatched chicks were used for determination of chick quality parameters at hatch according to the Tuna method. Forty-oneday old quail chiks from each treatment were divided to four replicate pens and raised for five weeks. At the end of the experiment (day 35 of age), the birds were slaughtered and the weigths of carcass indices and internal organs were determined. Moreover, the breast meat samples were collected and used for determination of malondialdehyde content. Data was analyzed by SAS (9. 1) according the compeletely randomized design with four treatments and four replicates each. Difference among the treatment means were tested for significance using Duncan test (P<0. 05). Results: The results showed that the consumption of different tomato pomace levels in breeder quail had no effects on progeny feed consumption, weight gain and feed conversion ratio during the weeks and whole experimental period (P>0. 05). Althogh there were no significant differences between the treatments for feed consumption yet the quials hatched from the eggs of 8% tomato pomace diet fed birds had numerically higher feed intake compared with the other groups. Moreover, there were no effects of treatments on internal organs and carcass characteristcs at day 35 (P>0. 05). Effect of tomato pomace on activity of newly hatched chicks (P>0. 05) was not significant. The down and appearance of newly hatched chicks of quails fed 8% tomato pomace had the highest quality between the treatment groups (P<0. 05). The quality of retracted yolk, eyes, navel area, remaninig membrane and remaining yolk of chicks from the quails fed 4% and 6% tomato pomace was highest and significantly higher than those fed the basal and highest tomato pomace level (12%) (P<0. 05). The legs of chicks belong to the birds fed the highest tomato pomace level was lowest (P<0. 05) but there was no significant difference between the other treatments for leg quality. The eyes quality of chicks from quails fed 4% tomato pomace was highest whereas the lowest eye quality was related to the chicks of 0. 0 and 12% tomato pomace fed birds (P<0. 05). The consumption of all totamto pomace levels decreased breast malondialdehyde content of progeny at week 5 (P<0. 05). The breeder quails fed 4% and 8% tomato pomace had the highest decrease in meat malondialdehyde content of progeny as compared to the control birds (P<0. 05). Conclusion: In conclusion, consumption of tomato pomace in the diets of breeder quails had no effects on performance parameters of progeny birds. Consumption of 8% tomato pomace in breeder quail improves the body antioxidant status and quality of newly hatched quality. tomato pomace feeding of 12% to quail breeder () increases the dietary fiber and possibly decrease the nutrients bioavailability and hence causes the lower quality of newly hatched chicks.
