Introduction : The number of publications in Scopus on this topic increased from less than 50 in 1995 to more than 250 in 2015. In other hand, inconsistency in results about the correlation between yeast and lactic acid bacteria as probiotics has been evident since the early publications on use in broilers. Methods : A meta-analysis was conducted to determine relationship between lactic acid bacteria and yeast as probiotics to broiler diets on the growth performance, relative organ weight, blood parameters, and immune response of the broiler. A database was designed based on published data that reported the use of probiotics on the broiler. The method used for selecting articles was based on the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) method. Articles selected were taken from PubMed, Web of science, Scopus, Google Scholar, and Science direct databases as well as individual. Results : The final database consists of 49 in vivo articles, 93 studies, and 225 treatments. The analysis statement in the system was a PROC MIXED procedure of SAS software. The level of probiotic increased (p <0.001) body weight, body weight gain, and feed intake of broiler. There was a reduction (p <0.01) on feed conversion ratio and mortality on the level probiotic given to broiler. Supplementation of probiotics in broiler diet increased (p <0.001) the weight of liver, spleen, gizzard, bursa of fabricius and carcass yield, while reduced (p<0.001) abdominal fat weight. The probiotic given increased the total of red and white blood cells (both at p < 0.001) but did not affect lymphocyte. Discussion : It can be concluded the yeast act as supporting agent that serves lactic acid bacteria as probiotic increases the growth performance, relative organ weight, blood parameters, and immune response of the broiler.

In this experiment, we investigated the effect of increasing levels of palm kernel meal containing α-β-mannanase replacing maize to growing-finishing hybrid duck on growth performance, nutrient digestibility, and carcass trait. One hundred and ninety- six hybrid ducks [(Peking x Khaki Campbell)] with 410.52 ± 95.25 g BW) were allotted to 5 dietary treatments with 9 ducks (unsexed) per pen and 4 replicates per treatments. These dietary treatments were: NC (negative control; maize-soybean-meal based diet), PKM25 (maize replacement with PKM α-β-mannanase 25%), PKM50 (maize replacement with PKM α-β-mannanase 50%), PKM75 (maize replacement with PKM α-β-mannanase 75%), PKM100 (maize replacement with PKM α-β-mannanase 100%). There was a curve linear decrease in the growing phase and finisher phase in feed intake as the level of α-β-mannanase palm kernel meal increased in the diet. Curvilinear, the result was presented no significant difference (P>0.05) on the initial body weight, growing and finishing phase body weight. The result of this study showed the used α-β-mannanase in the palm kernel meal presented a significant difference (P < 0.05) on the nutrient digestibility of dry matter and crude protein. Furthermore, Carcass traits showed the reflection in line with the final weight and internal organs were better to compare to control 0.5% using α-β-mannanase in the palm kernel meal. In summary, the increase of the level of palm kernel meal with α-β-mannanase enzyme was had a positive effect on the hybrid ducks and the replacement of palm kernel meal by 25% with the addition of the α-β-mannanase enzyme was able to improve digestibility and reduce abdominal fat of hybrid ducks.

Background and Aim: Developing simple, cost-efficient sheep feed will improve farmers’ incomes. Including coffee skin in feed offers the most technical method of increasing sheep weight gain. This study aimed to evaluate varying proportions of ensiled coffee skin replacing dried water spinach and determine the optimal combination for the growth performance, physiological and hematological profiles, and rumen fluid of sheep. Materials and Methods: Eighty-four animals were randomly allocated to the treatments, arranged in a randomized block design using the initial weight as a block. Seven treatment diets were adjusted and a 12-animal replication was used for each treatment. The treatments were as follows: T0: 30% maize stover, 30% dried water spinach, 5% pollard, 20% coffee skin; T1: 30% maize stover, 25% dried water spinach, 5% pollard, 5% ensiled coffee skin; T2: 30% maize stover, 20% dried water spinach, 5% pollard, 10% ensiled coffee skin; T3: 30% maize stover, 15% dried water spinach, 5% pollard, 15% ensiled coffee skin; T4: 30% maize stover, 10% dried water spinach, 5% pollard, 20% ensiled coffee skin; T5: 30% maize stover, 5% dried water spinach, 5% pollard, 25% ensiled coffee skin; T6: 30% maize stover, 5% pollard, and 30% ensiled coffee skin. The sheep were reared for 70 days.The parameters observed during the early stage included growth performance (initial body weight, LW gain, final body weight, and feed intake). At the end of periods, a representative sample of ruminal fluid (approximately 150 mL) was collected from slaughtered sheep, duplicated, and then incubated for 18 h and blood samples were collected from the sheep (jugular vein) in ethylenediaminetetraacetic acid tubes. Then, used to analyze various blood biochemical parameters. Results: The final body weights showed a linear curve increasing as the treatment increased (p < 0.05). The ensiled coffee skin tended to increase at 6 h incubation time, producing reduced methane gas (p < 0.05). However, in general, the use of ensiled coffee skin did not significantly alter the blood biochemistry of crossbreed sheep (p > 0.05). There was no significant effect on the protozoal population (p > 0.05). Conclusion: Increasing the level of ensiled coffee skin up to 30% replacing dried water spinach increased the final body weight of crossbreed sheep with no adverse effect. Keywords: biochemical blood, coffee skin, crossbreed sheep, ensiling, final body weight.
