“…Some forage and roughage usually used in tropical areas were Napier grass, natural grass, corn leaves, corn husk, and rice straw (Despal et al 2020). While the concentrated raw materials frequently used were copra meal, palm kernel meal, coffee husk, tofu waste, soy-sauce waste, brewer waste, and habbatussauda waste (Rosmalia et al 2021). High lignocellulosic roughage such as rice straw and corn husk are frequently used to substitute fresh forage, especially during the dry season when the forages grow slower.…”

Abstract. Despal, Faresty C, Zahera R, Toharmat R. 2022. Title The feeding behavior of dairy cattle under tropical heat stress conditions at smallholder urban farming. Biodiversitas 23: 3771-3777. Dairy cattle (Bos taurus) feeding behavior influences feed intake and affect animal welfare and disease management. This study observed dairy cattle feeding behaviors under tropical smallholder urban farming environments. Thirty-six cattle at the Kebon Pedes area of Bogor City were observed during 12 h feeding (6 am-6 pm). These traits included eating, ruminating, resting duration, and frequencies, measured using a continuous method. Temperature, humidity, temperature-humidity index (THI), feed and nutrient intake, milk production, and components were measured. The results showed that the cattle were in mild to severe heat stress. The average cow daily eating, ruminating, and resting frequencies were 6.61, 7.61, and 22.33 times, while the average eating, ruminating, and resting durations per cow per 12 h were 129.64, 105.67, and 484.69 minutes, respectively. The dry matter intake was 11.17 kg with a roughage to concentrate ratio of 0.73:1. The protein, ash, ether extract, and crude fiber intake were 10.25, 6.62, 3.67, and 22.08% DM, respectively. The average milk productions and fat contents were 11.01 L/head/d and 5.44%. The results showed that eating and ruminating levels correlated positively with feed, and CF intakes while resting correlated negatively. It was concluded that the cattle were in heat-stressed (THI of >78) condition, reduced DM intake, and deficient in energy and CP, which led to lower milk production but higher milk components, specifically milk fat. It is recommended to improve forage quality that promotes eating and ruminating and reduces resting durations, improving milk production.

“…Therefore, the particle size used must be larger than the pore size. Rahmat et al [9] used a 5 mm forage particle size, while Rosmalia et al [10] used 2 mm for concentrate. The 1 mm (1000 microns) feed particle used in the study was larger than the pore size of the fabric (50-100 microns), preventing undigested feeds from spilling out of the bags.…”

“…Consequently, in situ can be the choice to determine feedstuff degradation. Orskov and McDonald [8] developed the in situ method and used different incubation times, enabling researchers to study the fermentation kinetics of feeds in the rumen [9,10]. It was possible to study feed digestibility by incubating feed in the rumen using this method.…”

Background and Aim: Disposable imported nylon bags used in an in situ digestibility measurement restrict the effort of scientists to obtain more accurate information about ruminant feed quality due to their low affordability and environmentally unfriendly characteristics. This study aimed to find reusable local nylon fabrics to substitute imports. Materials and Methods: Five local fabrics (B1 = Abutai, B2 = Taffeta, B3 = Organza, B4 = N57, and B5 = M100) were used to make nylon bags and compared with the imported bag (B6 = Ankom technology). The research consisted of three steps: (1) Observing the similarity of the local nylon bag's hole number to the imported bag. (2) Testing feed in situ degradation (F1 = Napier grass, F2 = Cornmeal, and F3 = Dairy cattle total mixed ration) using bags B1-B6. (3) The reusability of the bag was tested using different washing methods (under running water [R1], rinse [R2], and ultrasonic water bath [R3]).Results: It was shown that the hole numbers of B1 (1223 hole numbers) and B2 (1245 hole numbers) were not significantly different from B6 (1248 hole numbers). It was shown with dry matter degradability measurement using the in situ method that there was no significant difference in feed solubility (a), potential degradability (b), and the effective degradation between local fabrics (B1-B5) and B6. According to the degradation rate (c), there were interactions between the feeds and fabrics. For F1, all local fabrics were similar to B6, while for F2, only B1 was different from B6. For F3, only B5 was different from B6. It was also shown by the organic matter degradability measurements that there was a similar trend. The exception was the solubility (a) component in F3, in which it was shown that B1 was also different from B6. It was shown in the reusable test that there was no difference in the weight of the bag before and after all washing methods. In contrast, the hole number increased due to the shrinking of the bag after drying in a 60°C oven. Conclusion:According to this in situ study, local nylon bag B2 can substitute imported bags. A lower drying temperature is suggested to prevent shrinking and make the bag reusable.

“…Previous studies reported that the RDP of SBM and SS were 66.0% and 76.0%, respectively [3,4]. High protein content in feedstuff is correlated with high RDP levels [5]. SBM and SS containing protein with high biological value and RDP levels might lead to excessive ammonia concentration in the rumen, therefore it needs to be protected to increase protein utilization.…”

Improving protein efficiency has become the main target in dairy farming. The feeding strategy for high-producing cows is directed by optimizing non-protein nitrogen utilization while maintaining post-ruminal digested bypass protein. Soybean and soybean meal are protein sources with high biological value but are highly degradable, so they must be protected. This study aimed to compare the effect of moist heating and formaldehyde treatments as a method for protecting protein to increase rumen bypass protein. Parameters observed include fermentation profile (rumen pH, NH3, total VFA, protozoa, and total bacteria population) and nutrient digestibility. Treatments tested were an unprotected diet as control (C1), moist heating protected protein (C2), and formaldehyde protected protein (C3). Data were subjected to ANOVA using Randomized Block Design followed by orthogonal contrasts. The results showed that both moist heating and formaldehyde treatments (C2 and C3) reduced NH3 and total VFA concentration (p<0.05) without affecting rumen pH, protozoa, and total bacteria count (p>0.05). Dry matter and organic matter did not affect by the treatments. In conclusion, both moist heating and formaldehyde methods could be used to protect feed protein and improve bypass protein in the dairy ration.
