Abstract

Mastitis is an inflammatory response caused by microorganisms or physical trauma that occurs in the udder. This study used an epidemiological survey approach in which the prevalence of subclinical mastitis and the factors that affect subclinical mastitis were calculated. The subclinical mastitis test uses indirect tests with California mastitis test reagents and direct tests with breed test methods. Risk factors for hygiene and bedding materials were identified via questionnaire aids. Data processing was performed via descriptive data and the chi-square test followed by relative risk correlation. The results of the present study revealed that the prevalence of subclinical mastitis in the Karanganyar milk shelter 2 cooperative of the Tani Makmur village unit, Lumajang, was 25.2% in the California mastitis test and 30.08% in the breed test. Cages made of nonrubber (p<0.05; relative risk [RR] = 7.519; 95% confidence interval (CI): 3,953–14,298]) in the breed test and (p<0.05; relative risk [RR] = 5.9; 95% confidence interval (CI): 3,019–11,559]) in the California mastitis test. Cleanliness with a gross value has (p<0.05; relative risk [RR] = 3.701; 95% confidence interval (CI): 2,360–5,803]) in the breed test and (p<0.05; relative risk [RR] = 4.01; 95% confidence interval (CI): 2,3576,788]). This is because materials that have a rough surface can increase the degree of trauma to the udder. In summary, the dirtier cage presented a higher rate of subclinical mastitis infection than did the clean cage. Dirty cages can be a place for the growth of pathogenic microorganisms that are detrimental to livestock.

Abstract

This study was conducted to determine the effects of remoistening on the chemical composition, fermentation characteristics, and ruminal digestibility of corn silage. Corn forage was harvested at the ½ milking stage containing 35% dry matter (DM) and then fermented for 21 days without remoistening (CON) or with 3 days wilting then remoistening to reach the original DM (TRT). This study was conducted with 4 replications per treatment in a mini silo (3 kg) and analysed via the independent sample t test. Compared with those of the CON silage, the pH and ammonia content of the TRT silage were greater (p<0.001). Similarly, the lactic acid, acetic acid and butyric acid contents of the TRT silage were lower (p<0.001) than those of the CON silage. Compared with those of the CON silage, the chemical composition of the TRT silage after fermentation included lower DM, organic matter (OM), and crude protein contents (p<0.001). Poor-quality TRT silage reduced the in vitro DM digestibility and OM digestibility of corn silage.

Abstract

This study aimed to evaluate the effectiveness of goat and sheep urine and determine the optimal dosage for alfalfa seedling growth. The experimental design used was a randomized complete factorial design consisting of two factors. Factor A is the urine type (goat or sheep), while factor B is the concentration of urine (5, 10, 15, 20, 25, 30, or 35%) + AB mix 400 ppm. The positive control consisted of 800 ppm AB mixture fertilizer, whereas the negative control received 0 ppm AB mixture. Each treatment was replicated 30 times. The results revealed a significant interaction effect (p < 0.05) between different types and levels of urine on media pH, plant height, and canopy biomass. Furthermore, the single factor of the urine level had a significant effect (p < 0.05) on the number of leaves. The results suggest that unfermented sheep urine liquid fertilizer at a level of 5% + AB mixture at 400 ppm is effective for alfalfa (Medicago sativa) seedlings. A relatively high urine level (? 10%) decreases the growth of plant vegetative tissue and has the opportunity to produce an abnormal leaf color (pale green).

Abstract

This research aims to identify the characteristics and production of fodder at different harvest times by establishing a hydroponic system to ensure a continuous supply of feed for dairy cows. The study comprises two phases. Phase I examines the production and nutrient quality of hydroponic fodder as a substitute for forage. This phase was conducted experimentally via a 2x3 factorial completely randomized design (CRD) design. Factor I = Plant type (maize and rice). Factor II = harvest time (7 days, 10 days, and 13 days). Phase II involves assessing the palatability of maize and rice plants as hydroponic fodder for dairy cattle. The data were analysed via a 2x2 factorial RAL design. Factor I = Plant type (maize and rice). Factor II = harvest time (10 days and 13 days). Maize and rice fodders harvested at various ages present the following characteristics: 1) As the harvest age increases (7, 10, and 13 days), the protein content of both maize and rice fodder increases, although overall production tends to decline after 10 days. The highest (fresh and DM) production occurs with maize fodder harvested at 10 days. 2) The elevated ADF and NDF contents in rice fodder up to 13 days result in lower dry matter digestibility (DMD) and organic matter digestibility (OMD) compared with those of maize fodder because of the presence of husks, which are the primary source of crude fibre. 3) Maize fodder is preferred by dairy cows owing to the number and size of its leaves and its vibrant green appearance.

Abstract

Alternative feed is important to consider so that feed production costs can be reduced and income can be increased. Mealworms are a source of animal protein with high nutritional value and a complete amino acid profile, making them an alternative feed source worth considering. However, the incorporation of mealworms into quail diets, particularly in Indonesia, has not been extensively studied, creating a gap that this research aims to address. The purpose of this research was to use mealworms (Tenebrio molitor) as an alternative feed to improve the productivity and egg quality of quail. This research used a completely randomized design (CRD) with 5 treatments and 4 replications. In treatment A, 0% MF was added to the rations; in treatment B, 5% MF was added to the rations; in treatment C, 10% MF was added to the rations; in treatment D, 15% MF was added to the rations; and in treatment E, 20% MF was added to the rations. The parameters observed were the productivity of laying quail (feed consumption, egg weight, egg production, and feed conversion) and the quality of quail eggs (crude protein, crude fat, yolk color, and quail eggshell weight). The results revealed that the addition of mealworm flour to the laying quail rations significantly affected (P<0.05) the feed consumption, egg weight, egg production percentage, and feed conversion of laying quail but did not significantly affect (P>0.05) egg crude protein content, egg crude fat content, yolk color, or eggshell weight. In conclusion, the addition of up to 15% mealworm flour to the laying quail feed mixture did not have a negative effect on quail performance or egg quality, indicating its potential as a sustainable alternative protein source.

Abstract

The fermentation methods used for buffalo milk sometimes vary among the regions where the Minangkabau people live. The physicochemical and microbial loads of fermented milk produced from swamp buffalo milk in this study were evaluated. The spontaneous method (in a bamboo tube), combination of spontaneous (in a bamboo tube) and backslopping (with the addition of a previous dadiah to the milk) methods, as well as its extension in the form of the backslopping method (with the addition of a dadiah to the milk in glass bottle), were applied in fermented milk manufacturing. The moisture content, pH, titratable acidity (TTA), and lactic acid bacteria load of the samples were analysed. The fermentation method had significant effects on the pH, TTA, and lactic acid bacteria load (P<0.05); in contrast, a comparable effect on moisture content was detected (P>0.05). The pH value of the samples prepared via the backslopping method and the combination of spontaneous and backslopping methods was lower than that of the spontaneous method (P<0.05), while a higher TTA was observed (P<0.05). Compared with the other methods, the combination method resulted in a higher lactic acid bacteria load, followed by the back slopping and spontaneous methods (P<0.05). The combination method might be considered the best method. In cases where bamboo is unavailable, the backslopping method can be used as an alternative method for buffalo milk fermentation to continue obtaining the live microflora benefits of the previous dadiah. In summary, confirmation from the original methods and the extended method provided more choices for the community to produce fermented milk from swamp buffalo milk.

Abstract

This study aimed to examine the effects of the interaction of the addition of vitamin C, the type of diluent, and the duration of storage at 5°C on the quality and fertility of Rooster Kampung spermatozoa and the fertile period of Red Kedu hen eggs. Semen was collected from 10 roosters subjected to vitamin C level treatment (0 mg, 0.1 mg, 0.2 mg, or 0.3 mg), two diluent types (lactated Ringer (RL) and skim milk + 50 mM glucose), and storage durations (0 hours, 3 hours, 6 hours, or 9 hours). The sperm samples meeting the quality standards were inseminated into 64 Red Kedu hens. Phase 1 of the study used a factorial randomised design (2´4´4) followed by variance analysis and orthogonal polynomial testing. Phase 2 applied the eight best result treatments from phase 1 via a completely randomised design with Tukey’s test for post hoc analysis. The results revealed a highly significant interaction effect (P<0,01) between vitamin C level and diluent type on motility, plasma membrane integrity (IPM), and sperm abnormality. The interaction effect of vitamin C level and storage duration had a very significant effect (P<0.01) on motility, IPM, and viability. The interaction effect of diluent type and storage duration significantly affected (P<0.01) motility and IPM. However, no significant effect (P>0.05) among all three variables was observed on fertility or the fertile period. In summary, the addition of 0.3 mg of vitamin C, lactated Ringer’s diluent, and 6 hours of storage at 5°C maintained sperm quality and resulted in 51.78±37.64 fertility and a fertile period of 15 days in Red Kedu hens.

Abstract

This study investigated the impact of temperature differences on broiler chickens’ blood profiles and performance. The experiment used two thermal environments, 20°C (T20) and 30°C (T30), which represent comfortable and heat-stress conditions, respectively. An 80-DOC (day-old chick) Ross strain broiler was incubated in two broiler houses. The temperature and relative humidity were measured daily. The temperature and relative humidity were measured daily. Blood samples were collected once at the end of the fifth week, while performance measurements were recorded during the nursery and treatment periods. The data were analysed descriptively. Broiler chickens in the T20 treatment experienced ambient temperatures of 24–26°C with 74–80% relative humidity, whereas those in the T30 treatment experienced temperatures of 30–32°C with 75–78% relative humidity. The hematological values remained within normal physiological ranges: erythrocytes ranged from 3.16–3.41x106/mm3, haematocrit ranged from 25.47–27.02%, haemoglobin ranged from 10.27–10.43 g%, and leukocytes ranged from 8.65–15.40x103/mm3. Broiler chickens reared at high temperatures presented heat stress, as indicated by the ratio of heterophiles to lymphocytes being 0.59. Heat stress resulted in reduced feed consumption, lower body weight gain, decreased final body weight, and an increased feed conversion ratio.

Abstract

This study aimed to evaluate the chemical composition, in vitro fermentation characteristics, and nutrient digestibility of local forages from Biak Utara District, Biak Numfor Regency, Papua. Eleven forage species commonly consumed by ruminants were collected, combined with elephant grass (Pennisetum purpureum) at a ratio of 64.2:35.8, and incubated in vitro for 48 h in cattle rumen fluid. The chemical composition, pH, ammonia-nitrogen (NH?-N) content, volatile fatty acid (VFA) content, gas production, methane (CH?) content, and in vitro digestibility of dry matter (DMD) and organic matter (OMD) were determined. The data were analysed via ANOVA followed by Duncan’s multiple range test. The results revealed wide variation in the crude protein (13.0–25.2%) and fibre fractions (NDF 33.2–61.6%; ADF 32.0–53.8%; hemicellulose 1.2–19.3%), which significantly affected fermentation characteristics and nutrient digestibility. The NH?-N concentration (29.5–40.9 mg/100 ml) exceeded the minimum threshold required for microbial protein synthesis. The total VFA concentration ranged from 61.3 to 81.2 mM, with higher values in forages with lower fibre fractions. Total gas and CH? production also varied, with the highest values observed in combinations with Garcinia dulcis and Morinda citrifolia. These combinations also had the highest DMD and OMD values (63.2% and 62.4%, respectively), whereas Ficus recemosa yielded the lowest values. In conclusion, the nutritional quality and fermentability of local forages are strongly influenced by the balance between the crude protein and fibre fractions. Forages with lower NDF and ADF contents and adequate protein levels improved digestibility and fermentation, indicating their potential to increase ruminant productivity in Biak Numfor Regency.
