Abstract

This study aimed to evaluate the feeding practices and nutritional intake of Ongole crossbred (PO) cattle in Kebumen, Central Java. This study focused on body condition scores (BCSs) and their implications for cattle performance. The parameters observed in this study included the feed composition, nutrient content, and impact of different BCSs on nutrient intake. The results of this research revealed that PO cattle with poor BCS did not receive sufficient feed, resulting in suboptimal nutrient intake. Moreover, those with medium BCS receive sufficient feed but still lack protein intake. In contrast, PO cattle with optimum BCS demonstrated the higher performance compared to other BCS groups, with crude protein intake of 0.57 kg (8.81%), 0.15 kg of extract (2.32%), 2.08 kg of crude fibre (32.15%), 3.81 kg of neutral detergent fiber 58.89%), 2.27 kg of acid detergent fiber (35.08%), and 4.00 kg of total digestible nutrient (61.82%) of the total dry matter intake, amounting to 6.47 kg. The findings underscore the importance of proper feeding practices tailored to the nutritional needs of cattle to optimize cattle performance

Abstract

This research was conducted to determine the impact of substituting commercial feed with agroindustrial by-product feed on the growth performance of pigs in the grower phase and the benefits obtained by farmers. A total of 20 pigs aged 18 weeks were tested in a randomized block design with four treatments and five replications. The feed treatments were P0= commercial feed (CP 552), P1= 50% CP552 and 50% agroindustry feed, P2= 100% agroindustry feed, and P3= P2 feed with the addition of phytase and mannase enzymes. The results showed that feed consumption, body weight gain, and feed conversion were not significantly different among the treatments. The digestibility of the P0 was significantly higher than that of P1, P2, and P3 (p<0.05). The digestibility of the P3 was not significantly different from that of the P1; however, it was significantly higher than P2 (p<0.05). The IOFC of P2 was higher than P0 and P1, while P3 resulted in the highest IOFC among treatments. It can be concluded that utilizing feed containing agro-industrial by-products could substitute 100% of commercial feed in growing pigs and provides 60% higher income than commercial feed. Moreover, additional phytase and mannase enzymes on agroindustrial by-products feed might provide 89% higher income than commercial feed.

Abstract

The high feed price, mainly commercial feed, made it unaffordable for smallholder-scale pig farmers in Toraja. As a result, rations were given to pigs without considering nutritional content. This study aimed to substitute commercial feed with agro-industrial by-product-based feed in starter pigs. A total of 20 local breeding pigs, aged 13 weeks, were tested using a randomized group design consisting of 4 treatments with 5 replicates. The treatments were P0 = 100% commercial feed as control; P1 =substitution of 50% with agro-industrial by-product feed; P2 = substitution of 100% agro-industrial by-product feed; P3 = P2 + phytase and mannanase enzymes. ANOVA and Duncan test were performed for analysis the data. The results showed that substituting commercial feed with agro-industrial by-products feed had no negative impact on dry matter (DM), organic matter (OM), and crude protein (CP) intake. However, substituting commercial feed with agro-industry feed significantly decreased the digestibility of feed nutrients. The lowest digestibility values were obtained from the 100% agro-industrial by-product-based feeds at 77.81%, 80.17%, and 38.15% for DM, OM, and neutral detergent fiber (NDF), respectively. Interestingly, adding the enzyme mannanase and phytase (P3) significantly increased the digestibility values of DM, OM, and NDF to 82.79%, 85.14%, and 53.67%. This study also showed no effect of commercial feed substitution up to 50% on the performance of pigs in the starter phase. In addition, this practice can also increase farmers' income by up to 15%.

Abstract

Concentrate can improve livestock productivity due to its high protein content. Meanwhile, a high proportion of concentrate consumption in livestock can decrease the pH of the rumen and lead to a decrease in rumen performance. Leguminous plants that have high protein and are abundantly available are a potential source of protein and concentrate substitutes in livestock diets. This study aimed to evaluate the effect of Leucaena leucocephala (LL) and Indigofera zollingeriana (IZ) as concentrate substitutes in RDP: RUP-concentrate-based diet on degradation of dry matter degradability (DMD) and organic matter (OMD), digestible neutral detergent fiber (dNDF), in vitro true digestibility (IVTD), pH value, NH3 concentration, and total gas production. This study used a Randomized Block Design, consisting of seven treatments with four replications. The treatments were: T1 = control consist of 40% Pennisetum clandestinum (PC) and 60% concentrate (C) (RDP: RUP of concentrate = 60%:40% of crude protein), T2 = 40% PC + 45% C + 15% LL, T3 = 40% PC + 45% C + 15% IZ, T4 = 40% PC + 30% C + 30% LL, T5 = 40% PC + 30% C + 30% IZ, T6 = 40% PC + 30% C + 15% LL + 15% IZ, T7 = 40% PC + 30% LL + 30% IZ. This study reported that leguminous as concentrate substitutes in RDP: RUP-concentrate-based diet significantly affected nutrient digestibility and total gas production, while pH value and NH3 concentration did not differ among experimental diets. The supplementation of LL 15-30% and IZ 15-30% in RDP: RUP-based diet increases DMD, OMD, IVTD, and total gas production. The combination of LL and IZ 15-30% in RDP: RUP-based diets tend to depress OMD, while other parameters did not differ among experimental diets. The highest DMD, OMD, IVTD, and total gas production were observed in the experimental diet with 30% of IZ substitutes in the RDP: RUP-concentrate-based diet. In conclusion, 30% Indigofera zollingeriana as a concentrate substitute in RDP: RUP-concentrate-based diet can increase nutrient digestibility and optimize rumen fermentation characteristics.

Abstract

Zeolite had been widely investigated in animal feed for its ability to improve feed efficiency and reduce ammonia emissions, and nano-zeolite offered greater adsorption capacity due to its expanded surface area. This study evaluated the effects of nano-zeolite supplementation on ammonia (NH₃), volatile fatty acids (VFA), the VFA/NH₃ ratio, and pH during in vitro rumen fermentation. A two-factor randomized block design (6 × 6) with four replicates was used. Incubation time (2, 4, 8, 12, 24, and 48 h) served as the first factor, and six dietary treatments served as the second factor: control, urea-supplemented concentrate, inactivated nano-zeolite, activated nano-zeolite, urea-impregnated inactivated nano-zeolite, and urea-impregnated activated nano-zeolite. Nano-zeolite, whether active or urea-impregnated, did not significantly improve rumen fermentation efficiency based on NH₃, VFA, or VFA/NH₃ ratio. All nano-zeolite diets performed similarly to the control and urea-only diets. Fermentation efficiency peaked at 4 and 8 hours of incubation, indicating that nano-zeolite combined with urea supported stable fermentation, particularly during early to mid-incubation.
