Probiyotiklerin Eimeria tenella İle Enfekte Broiler Piliçlerin Sağlık Durumu ve Verim Performansı Üzerine Etkileri

Abstract

A probiotic containing Pediococcus acidilactici and Bacillus subtilis (Smart ProLive) at a 1x10 7 CFU/mL dose in drinking water were given continuously from the d 14 to the end of the treatment (d 35) in broiler chickens. Experimental infection was produced by oral gavage of sporulated E. tenella oocysts at 14 th d of age. Feed consumption (FC), live body weight (LBW) and feed consumption rate (FCR) were measured at weekly basis. Villus height and crypt depth in cecum and ileum, and antibody titers in the blood were performed at 28-day-old. Probiotics appeared to be superior to salinomycin on the villus height and crypt depth of cecum and ileum (P<0.05). A numerical, but not significant (P>0.05) improvement on the LBW was determined at the groups of probiotic and salinomycin+probiotic than that of control and salinomycin groups. Nevertheless, FC and FCR results of the probiotic and salinomycin+probiotic groups were good than that of control and salinomycin groups. Probiotics were effective on the villus heights and crypt depths than that of salinomycin alone. Salinomycin appeared to be good only than control group in all the parameters. Not a significant difference from antibody titers was existed among the groups. Based on these results it can be concluded that a good source of probiotics can be used as natural antimicrobial growth promoters in replacement with forbidden anticoccidials in broiler rearing. Probiyotiklerin Eimeria tenella İle Enfekte Broiler Piliçlerin Sağlık Durumu ve Verim Performansı Üzerine EtkileriÖz Pediococcus acidilactici ve Bacillus subtilis içeren bir probiyotik (Smart ProLive) 14. günden 35. güne kadar içme suyu ile birlikte sürekli olarak 1x10 7 KOB/mL dozunda broiler civcivlere verildi. Deneysel enfeksiyon 14 günlük civcivlere sporlu E. tenella ookistleri ağız yoluyla verilerek yapıldı. Yem tüketimi, canlı ağırlıklar ve yemden yararlanma oranları haftalık olarak takip edildi. Sekum ve ileumda villus yüksekliği ve kript derinliği ile antikor titre analizi 28 günlük civcivlerde yapıldı. Probiotiklerin sekum ve ileumda villus yüksekliği ve kript derinliği üzerindeki olumlu etkisi salinomisinden daha üstün bulundu (P<0.05). İstatistiki önem ortaya çıkmamakla birlikte (P>0.05) canlı ağırlık artışı probiyotik ve probiyotik+salinomisin grubunda control ve salinomisin grubuna göre daha yüksek bulundu. Ancak, yem tüketimi ve yemden yararlanma konusunda probiyotik ve probiotik+salinomisin grupları kontrol ve salinomisin gruplarındakinden üstündü. Salinomisin tüm parametrelerde sadece control grubundan üstün olabildi. Antikor titreleri bakımından gruplar arasında fark gözlenmedi. Elde edilen bulgular ışığında iyi bir probiyotiğin kullanımı riskli ve direnç oluşumuna neden olabilecek antikoksidiyaller yerine doğal antimikrobiyal büyütme faktörü olarak kullanılabileceği öne sürülebilir.

Influence of Pediococcus pentosaceus GT001 on Performance, Meat Quality, Immune Function, Antioxidant and Cecum Microbial in Broiler Chickens Challenged by Salmonella typhimurium

“…The histological segments were examined using a Leica DM500 light (Wetzlar, Germany). The crypt depth was measured from the root of the lower limit of the crypt to the villi–crypt junction, while the villi height was measured vertically from the villi–crypt junction to the tip of the villi [ 13 ].…”

Modulation of the immune system of chickens a key factor in maintaining poultry production—a review

“…Probiotics most often belong to the genus Lactobacillus, Bacillus, Lactococcus ( Park et al, 2016 ), Enterococcus, Bifidobacterium , and Saccharomyces ( Adhikari and Kim, 2017 ). Many studies have confirmed the health-promoting effect of probiotics on the organism of birds in the aspect of the digestive tract ( Biswas et al, 2019a ), the immune system ( Zhang et al, 2016 ; Fathi et al, 2018 ; Alaqil et al, 2020 ), intestinal microbiota ( Khan et al, 2020 ) or by preventing bacterial infections ( Smialek et al, 2018 ; Ahmed et al, 2019 ; Tabashsum et al, 2020 ), viral ( Al-Khalidi et al, 2020 ), and protozoan ( Erdoğmuş et al, 2019 ). The immunomodulatory properties of probiotics include changes in the levels of interleukins (IL-2, IL-10) and immunoglobulins (IgG, IgA) ( Rajput et al, 2013 ), as well as an increase in the weight of the immune system organs (spleen, thymus, bursa fabricii), as demonstrated by the use of Bacillus subtilis in ducks ( Guo et al, 2016 ).…”

Advances on Probiotics Utilization in Poultry Health and Nutrition

“…Increased growth performances along with decreased levels in serum and meat cholesterol in male duckling [26]. It has been found out that dietary supplementation with probiotics, Pediococcus acidilactici and B. subtilis in water, improves the intestinal health and resistance of chickens against coccidiosis-causing Eimeria species [27].…”
