ABSTRACT:

Antibiotic growth promoters were widely used to improve broiler performance however with the increased problems associated with its use such as their residues and subsequent resistance to bacteria has caused them to replace antibiotics for herbs and plant extract alternatives (phytogenics). One hundred and fifty Cobb500 chicks and 150 Ross 308 chicks were distributed from two to six weeks of age into three treatments (50 birds/ treatment) which included 2% Moringa oleifera supplemented ration (M 2%), 3% Moringa oleifera supplemented ration (M 3%) and control treatment for both breeds, moreover, chicks of each treatment were distributed into five replicates (10 birds/replicate). Ross breed achieved significantly higher (P< 0.05) body weight, weight gain, feed intake, feed conversion ratio, carcass weight and breast muscle weight compared to Cobb breed. Moreover Ross breed responded better to dietary Moringa oleifera supplementation than Cobb. Firstly M(3%) was decreasing body weight and weight gain than M(2%) however with time the opposite occurred with carcass cuts and internal organs weights were not affected significantly (P< 0.05) with dietary Moringa oleifera supplementation. Ross 308 breed showed an increase in HI titer against Newcastle disease virus than Cobb 500 breed. Finally we concluded that the Ross breed respond better to dietary Moringa oleifera supplementation. However, more future researches are required to study the response of different broiler breeds to different dietary Moringa levels.

ABSTRACT:

Probiotics are live microbial food ingredients that have a beneficial effect on human health. Intake of probiotics improves feed intake, egg production and egg quality in laying breeds. The objective of this study was to evaluate the effect of the probiotic lactobacillus species supplementation on productive traits of White Leghorn chicken. For this purpose, 30 samples of cow milk were collected from Haramaya university dairy farm during the period from May to August 2015. The probiotic properties of each isolates were confirmed by simulating gastrointestinal tract conditions. Based on physiological and biochemical tests Lactobacillus acidophilus and Lactobacillus plantarum were isolated. The experimental design used in this experiment was single-factor Completely Randomized Design (CRD) with treatments basal feed (control), supplementation of L. acidophilus (T2), L. plantarum (T3) and their combination (T4) and a 5% (P< 0.05) level significance was used. Supplementation of Lactobacillus species improved the Feed Intake (FI), Hen Day Egg production (HDEP) and egg weight. The FI recorded were 98.9 g/day/hen, 99.8 g/day/hen, 101.8 g/day/hen and 105.0 g/day/hen in control, T1, T2 and T3 respectively. HDEP of 0.31%, 0.33%, 0.33% and 0.34% were recorded at control, T1, T2 and T3 respectively. The egg weight of the control treatment, T1, T2 and T3 were 50.8g, 51.4 g, 51.4g and 51.9g respectively. Probiotic Lactobacillus species (L. acidophilus and L. plantarum) improves the productive traits of the laying flock. Chicken received the combination of probiotic lactobacillus species significantly perform best in FI, HDEP and egg weight.
