EVALUATION OF BAKER'S YEAST (Saccharomyces cerevisiae) SUPPLEMENTATION ON THE FEEDING VALUE OF HYDROPONIC BARLEY SPROUTS FOR GROWING RABBITS

Abstract

ABSTRACT:This study is consisted of two experiments and aimed to determine the nutrient composition and feeding value of the hydroponic barley fodder (HBF) and that HBF irrigated with bakers' yeast (HBFY) for the growing Californean (CAL) and White New Zealandean (NZW) rabbits. The first experiment included 36-weaned rabbit males, 18 rabbit males from each of CAL and NZW breeds, which were housed in 18 paired cages. The nine replicates (2 rabbits in each replicate) of each breed were then allotted randomly to three feeding treatment groups: Control. Basal diet, T1. Basal diet + HBF, and T2. Basal diet + HBFY. The rabbits were adapted to the tested fodders for one week, and the data collection continued for six weeks. The second experiment followed the same design, but using female rabbits instead of males. The fresh-8-day HBF and HBFY contained 17.30% and 16.84% dry matter, 17.75% and 16.68% crude protein, 15.90% and 15.67% crude fiber, respectively. The one kg of barley grains yielded 6.12 kg of fresh HBF, versus 6.02 kg of fresh HBFY/ kg grains. The results of Exp. 1 showed that the male rabbits provided with fresh HBF recorded the highest body weight, body weight gain and carcass weight, while the HBFY males had the worst (P<0.01) feed conversion ratio. In Exp. 2, the HBFY females had the lowest BW and BWG and the worst FCR value. In both trials, the male and female rabbits which were provided with fresh HBF had a cheaper feed cost per gain than those of the control group, while the HBFY rabbits had the most expensive value. Besides, the tested treatments showed inconsistent impacts on the feed and fodder intake values, while they did not show any sifgnificant effect on the dressing percentage, carcass cuts, body muscles, or internal organ weights. Conculsively, the results therefore revealed that feeding the growing male or female rabbits with the HBF displayed considerable nutritional benefits, while the HBFY is not recommended.

Fructooligosaccharide Supplementation Boosts Growth Performance, Antioxidant Status, and Cecal Microbiota Differently in Two Rabbit Breeds

“…Comparable findings reported that a diet supplemented with S. cerevisiae and probiotics accelerated the BWG and FCR of NZW rabbits [ 34 , 35 ]. By contrast, Rotolo et al [ 36 , 37 ] found that the dietary supplementation of S. cerevisiae did not affect rabbits’ BW, BWG, and FCR. Additionally, Zarei et al [ 38 ] reported that dietary prebiotics did not modify FCR in laying hens.…”

Impact of rhizosphere bacterial strains usage as biofertilizers inhibiting fungal growth and enhance the growth and immunity of sprouted barely an alternative feed for livestock

“…Hydroponics fodders have a source of chlorophyll and contain a grass juice factor that able to improve the performance of the animals (21). Many studies on the use of sprouted grains were done as (22) who reported that barley fodder consider a good for rabbit performance.…”

Research and Application of Factory Hydroponic Technology in Wheatgrass Greenhouse

“…In addition, when people consider the use of green feed as alternative feed, the improvement of livestock product quality itself is not the main goal, but to reduce the cost of feed required per unit of production. Because for aquaculture enterprises, any slight re-duction in feed used will significantly increase production margins and profits, of which feed costs account for about 75% of the total production costs [11][12][13][14]. In this study, wheat hydroponic forage can be eaten with roots, which improves the utilization rate of forage and the digestibility of forage in livestock by 50% [15]; Significant reduction of digestive diseases in livestock; Avoid planting forage that occupies a lot of arable land; The unique advantages of low energy consumption, easy operation, easy maintenance and low operating cost have played an exemplary and leading role in the development of animal husbandry in arid areas [16].…”
