Introduction

The increase in feed prices especially corn is feared to make chicken farmers in Indonesia damaged. However, several researchers stated that increasing chickens’ productivity in Indonesia requires genetic quality improvements in the breeding program. It is also necessary to improve feed conversion efficiency, which can reduce production costs (Winaya et al., 2023; Suyatno et al., 2023). In contrast, Indonesia is a producer of organic waste that has the potential to be used as feed, but currently, it only pollutes the environment (Setyobudi et al., 2018, 2021b).

With an average waste of 30 × 106 t yr–1, 40 % organic, Indonesia is one of the highest waste-generating countries (Hidayat, 2021; Khoiron et al., 2020; Setyobudi et al., 2021a; Tonda et al., 2022). Its government has attempted steps and innovation programs on waste management by issuing Government Regulation No 27/2020 (Asmawati et al., 2021, 2022; Handajani et al., 2021; Rudovica et al., 2021; Setyobudi et al., 2019, 2022; Valdez-Arjona and Ramírez-Mella, 2019). At the same time, researchers have been persevering to find amiable schemes specifically to relegate organic waste. Burlakovs et al. (2022), Chia et al. (2020), Harsono et al. (2016), Setyobudi et al. (2018), Soleh et al. (2020), Susanto et al. (2020a, b) and Wuryantoro et al. (2021) have agreed that waste can serve as a source of renewable energy.

Regarding biogas, some of the researchers (Adinurani et al., 2013; Hendroko et al., 2014, 2015; Novianto et al., 2020) suggest employing a two-stage digester to optimize pH in an anaerobic fermentation process. Other researchers advocate turning organic waste into fertilizers with the ability to improve soil nutrients (Anwar et al., 2015; Budiono et al., 2021; Hapsoh et al., 2016; Kadir et al., 2016; Karnchanawong and Nissaikla, 2014; Oliveira et al., 2017). In animal farming, the potential to reuse organic waste as feed is also noted (Kierończyk et al., 2020; Muktiani et al., 2013; Pinotti et al., 2021, Prasetio et al., 2021; Widiyastuti et al., 2015). Vegetable remains are feasible for ruminant cattle (Harsányi et al., 2020; Stamer, 2015), and “aking rice” (dried rice) fits for poultry (Tonda et al., 2022; Zulfikar et al., 2014). Aking rice is made of rice remains, sundried after cleaning, and rinsed to reach a water content of < 14 %

(Tonda et al., 2022).

Zulfikar et al. (2014) have stated that aking rice can satisfactorily substitute corn, the most common poultry base feed. Approximately 65 % of feed components including corn are imported, making it the highest spending in poultry production cost. When corn is off-season, its price can be so high that the farmers call for alternatives to stabilize their production costs (Alqaisi et al., 2019; Macharia et al., 2020). With a water content of 12.58 %, protein of 8.96 %, crude fat of 0.43 %, and crude fiber of 0.59 %, aking rice has similar nutrient contents to corn and is therefore viable as a substitute (Tonda et al., 2022).

Zulfikar et al. (2014) have confirmed the feasibility of aking rice to replace rice bran while the protein and crude fat are similar, aking rice has less crude fiber. Therefore, referring to the recommendation of SNI 8173.1:2015 (SNI: Standar Nasional Indonesia), the maximum limit of 5 % crude fiber content in poultry feed, aking rice, should serve better as base feed.

Processing rice as organic waste into aking rice is a positive endeavor to preserve the environment from degradation due to soil, water, and air pollution (Krumina et al., 2015; Pinotti et al., 2021; Valdez-Arjona and Ramírez-Mella, 2019). Not only does it play a role in cutting down national waste generation, but this scheme also supports animal farming by offering a cheaper alternative to constantly rising feed costs. However, no literature or findings are yet to discover whether “aking rice” is palatable for chickens, and this fact becomes the basis of this study.

Materials and Methods

This research had been authorized by the Ethical Commission on Health Studies of the Faculty of Medicine of the University of Muhammadiyah Malang (No. E.5a./2022/KRPK-UMM/X/2022) and was conducted in Lumajang, a regency in East Java, Indonesia (112o, 53’ to 113o, 23’ E and 7o, 54’ to 8o, 23’ S) happens to be a broiler chicken production area in the province, with precipitation of 1 500 mL to 2 500 mL yr–1 and temperature of 23 oC to 34 oC. Therefore, turning rice remains into “aking rice” is customary there, which is then given to their poultry or sold.

Materials

Broiler chickens aged 35 d gained from PT. Zakiyah Jaya Mandiri, with an average weight of 1870 g ± 290 g,

were employed, 27 chickens in total. All chickens were in good health before treatment. The number of chickens was 27, referring to the range of materials in previous research (Amechi, 2020; Arrozola and Torrey, 2019; Buckley et al., 2015). The ambient temperature and lighting provided are also the same. Before the study, the chickens were fed the same feed for 7 d. The composition of the feed given before treatment is as follows (Table 1).

 

Table 1: Feed composition before treatment.

No	Ingredient	Composition
1	Poultry ME (kcal kg–1)	3 200.00
2	Crude protein (%)	20.00
3	Crude fat (%)	4.75
4	Crude fiber (%)	3.84
5	Calcium (%)	0.90
6	Available phosphorus (%)	0.45
7	Na (%)	0.15
8	Lysin (%)	1.00
9	Metionin (%)	0.38

 

 

As per the experimental method, three treatments of corn (T1), aking rice (T2), and rice bran (T3) were prepared (Figure 1). Each treatment was given to a unit of three in three replications. First, treatments were measured and administered simultaneously four times in the morning and two times in the afternoon – for 30 min. The remaining treatments were then measured to find the total consumption of each unit.

Aking rice is processed from leftover rice wasted in markets, restaurants, household waste, etc. Leftover rice is collected, cleaned of other ingredients, and rinsed under running water. Clean food scraps are dried in the sun or baked in an oven until dry with a moisture content < 14 %. Aking rice is processed into flour and ready to be given or formulated into chicken feed.

Feed intake

An approach to discovering the palatability of feeds in chickens is by measuring their consumption in specific periods (Winarso et al., 2018; Wirdateti et al., 2001). Scaled before administered, each treatment of 1000 g was served for 30 min, and the remains were then scaled to record the consumed amounts. The figures were then used to find the feed intake rates by running Equation 1:

Feed intake= Initial feed weight – final feed weight ..(1)

Feeding duration

Another way to determine the palatability of feeds is by measuring the length of time chickens take to eat in each feed administration (Alagawany et al., 2019; Campanile et al., 2011). Once all three chickens in a unit stopped pecking on their feed completely, the finish line of eating was set. Again, a stopwatch was involved in assessing the feeding duration.

Statistical analysis

Data gained from the experiment were tabulated in MS Excel and then ran through a one-way Analysis of Variance (ANOVA) (Damat et al., 2020, 2021; Mandey et al., 2017). Should any differences in the treatments occur, the Least Significant Difference (LSD) test would follow (Tejeda and Kim, 2021; Winaya et al., 2019).

Result and Discussion

Feed intake

Figure 2 shows that T1 rated 59.89 g with a standard deviation of 24.83 g is the highest feed intake average. The relatively clustered ratios are evident in the homogenous spread of data. The standard deviation rates of T1 and T3 are also spread near each of their rates. One-way ANOVA has confirmed significant differences in the three treatments, and LSD has also revealed distinctions in the average feed intakes of T1, T2, and T3.

 

Chickens are visually attracted to bright colors, particularly when contrasted to the surroundings, such as red and yellow (Mendes et al., 2013; Seifert et al., 2020), which is the reason behind colors used for their feeding and drinking equipment. That corn and “aking rice” are brighter in colors presumably helps to boost their palatability rates. Yet, another factor must make “aking rice” preferable, and its shape is the answer. Feed shapes and forms also determine palatability (Al-Nasrawi, 2016; Karimirad et al., 2020). Chickens favor pellets or grains rather than powder (Attia et al., 2012; Ege et al., 2019) since they are easier to pick with their pointy beaks (Beg et al., 2011; Mingbin et al., 2015).

Additionally, nutrient contents of crude protein, crude fat, and crude fiber in the feed are relevant to its consumption quantity (Campanile et al., 2011; Mingbin et al., 2015) since chickens like nutritious feed better (Bovera et al., 2015; Liu et al., 2011). Therefore, the nutrient contents of the three treatments are compared and drawn in Figure 3.

 

It indicates that the crude protein contents of all treatments are equal, but crude fat and fiber contents in rice bran are much higher than in corn and aking rice. The result corroborates the finding of Barker and Sell (1994) and Widodo et al. (2019, 2021) that chickens only require not more than 5 % of fat in their feed. Furthermore, once they are filled with fat, chickens stop eating even after a small amount.

Feeding duration

As depicted in Figure 4, it is apparent that the highest feeding duration rate goes to T2 at 680 s with a standard deviation of 295 s, while T3 is the lowest at 140 s with a standard deviation of 84 s. One-way ANOVA has corroborated significant differences in the three treatments related to feeding duration, and LSD has also shown distinctions in the feed duration rates of T1, T2, and T3.

 

Environmental factor affects feeding behavior in chickens. For example, in a high temperatures, chickens tend to eat less to ease their metabolism and, consequently, lower their body temperature (Lara and Rostagno, 2013; Lin et al., 2006) as well as drink more to respond to it (Hassan et al., 2009; Sugito et al., 2020). In this experiment, the temperature was relatively stable at 26 ℃ and, therefore inconsequential. However, a different duration may occur when feed is administered under heat stress; as discussed by Tonda et al. (2023a), chickens in an environmental temperature of > 30 ℃ showed a better performance index when fed with “aking rice.”

Crude fiber also matters in chicken feeding duration (Cerrate et al., 2019; Mandey et al., 2017) since more fiber in feed adds to its bulkiness, making chickens get fulfilled more easily (Jiménez-Moreno et al., 2016; Tejeda and Kim, 2021). Thus, the shorter feeding duration of rice bran is due to its higher crude fiber content than in corn and “aking rice.”

Developing “aking rice” as a feed ingredient for broilers can increase productivity because “aking rice” has a higher protein content than corn and rice bran. In addition, “aking rice” also has a lower fat content, so it can reduce the fat in broiler meat (Tonda et al., 2023b).

According to Tonda et al. (2022), giving dry rice affects feed costs because the price of dry rice is lower when compared to substituted feed such as corn. The use of dry rice is essential for breeders because the feed cost is the most significant cost of broiler farming. The lower the feed price, the greater the profit or profit earned. This research shows how vital feed efficiency is in broiler farming.

Processing food waste into feed ingredients can provide several benefits, including First, reducing the amount of food waste: Processing food waste into feed ingredients can help reduce the amount of food waste disposed of and reduce environmental pollution problems caused by food waste. Second, improve the efficiency of feed production: Processing food waste into feed ingredients can help increase the efficiency of feed production because it can reduce dependence on feed ingredients that are expensive and difficult to obtain. Third, increase livestock productivity: By using feed ingredients made from food waste, farmers can increase livestock productivity because the feed ingredients used are cheaper and more readily available. Fourth, reduce production costs: processing food waste into feed ingredients can reduce production costs because the raw materials used are readily available and free of charge. Fifth, it can improve animal health: if the food waste has been appropriately processed and meets the government’s quality and safety standards, the feed ingredients can improve animal health. Sixth, this potential will become a new business opportunity for the development of feed ingredients. However, keep in mind that the production of aking rice as a feed ingredient must meet the feed quality and safety standards the government sets.

Conclusions and Recommendations

The highest feed intake and duration rates recorded by “aking rice” are evident in its better palatability than corn and rice bran. It is, therefore, conclusive that “aking rice” is feasible for an alternative energy source. A new prospect in rice waste management and business is open to saving the environment from organic waste and supporting animal farming with a constant supply of alternative quality feed equal to corn.

Novelty Statement

The data obtained in this study that aking rice has higher palatability than corn and rice bran has never been observed nor published before. In addition to price and nutrient content, palatability is essential in choosing the best feed. Therefore, further product development on aking rice should help the supply of alternative feed while also helping the lessening of organic waste pollution.
