The Effects of Yucca Schidigera Extract and Multi-carbohydrase in Different Crude Protein Diets on Growth Performance, Nutrient Digestibility, Carcass Parameters and Excreta Noxious Gas Contents in Broilers

Abstract

The scarcity and increase in the price of animal feeds have attracted the attention of nutritionists to address this issue. The inclusion of plant extracts and enzymes to protein-reduced diet could be a feasible strategy to reducing the feed cost. Therefore, the purpose of this study was to assess the impacts of Yucca schidigera extract and multi-carbohydrase in low crude protein (CP) diets of broiler on growth performance, nutrient digestibility, carcass metrics, and noxious gas levels in the excreta. A total of 480, 1-d-old ROSS 308 were randomly allocated into 4 dietary treatments, six replication, and 20 birds/cage. Phase 1, T1(CP 21%, ME 2,969 kcal/kg); T2 (CP 19%, ME 2,863 kcal/kg + 0.02% Yucca); T3 (CP 17%, ME 2,865 kcal/kg + 0.02% Yucca); T4 (CP 17%, ME 2,861 kcal/ kg + 0.02% Yucca + 0.1% multi-carbohydrase). Phase 2, T1 (CP 19%, ME 3,086 kcal/kg); T2 (CP 17%, ME 2,977 kcal/kg + 0.02% Yucca); T3 (CP 15%, ME 2,978 kcal/kg + 0.02% Yucca); T4 (CP 15%, ME 2,978 kcal/kg + 0.02% Yucca + 0.1% 0.1% multi-carbohydrase). Although the addition of YS and multi-carbohydrase to the low CP diets on the growth performance did not improve, it revealed the positive result on the nutrient digestibility, carcass parameters, and noxious gas emission. Overall, broilers supplemented with YS 0.02% and multi-carbohydrase (0.1%) demonstrated the best production performances compared to the other treatment groups. Thus, a combination of YS and multicarbohydrase could be added to the diets with low CP to boost broiler production performance.

Evaluation of Carcass, Growth Performance, Hematological and Biochemical Parameters of Broiler Chickens Fed Additive of Onion Bulb Peel Powder

“…Our findings suggest that the inclusion of onion bulb peel powder enhanced improvements in carcass yield, growth performance, and certain hematological and biochemical parameters as positive changes were observed which suggests that the powder has potential health benefits on the chickens. [17,18]. This impact on hematological and biochemical parameters could be linked to the bioavailability of nutrients facilitated by the powder of onion bulb peel.…”

Effect of Dietary Almond Hull on Growth Performance, Nutrient Digestibility, Organ Weight, Caecum Microbial Counts, and Noxious Gas Emission in Broilers.

“…The guidelines of NRC (1994) were used to formulate the composition of the basic diet (Table 1). The broiler house room temperature was 33 ± 1°C for the first week, and then it was consistently reduced to 24 ± 1°C, with more than 60% retaining moisture (Munezero et al, 2022). A nipple drinker and a plastic feeder were attached to each pen, through which birds had free access to feed and water during the experiment.…”

“…After that, the dried samples were analyzed using AOAC standard methods (2022) for GE, DM, and N. UV absorption spectrophotometry (UV-1201, Shimadzu, Japan) was used to determine the levels of chromium. We followed the following formula to calculate digestibility: Digestibility=1-[(Nf×Cd)/(Nd×Cf)] ×100, where Nf = concentration of nutrient in excreta (% DM), Nd = concentration of nutrient in the diet, Cd = concentration of chromium in the diet, and Cf = concentration of chromium in the excreta (Munezero et al, 2022).…”

Effect of Achyranthes japonica extract on growth, digestibility, microbiota, gas emission, and meat quality in broilers fed different protein diets

“…Protein is the second-most vital and expensive nutrient component in ration formulation whose price are increasing day by day. Soybean meals are widely used in poultry’s diet [ 3 ] because they are a preferred source of protein, which contains well-balanced amino acids that are highly digestible. Reducing dietary protein while maintaining essential amino acid balance can be an effective technique to minimize feed price and nitrogen release into the environment [ 4 ].…”
