Abstract

This study aimed to evaluate the in sacco nutrient degradability of total mixed ration (TMR) silage containing intact and defatted black soldier fly (BSF) larvae. The study evaluated four dietary treatments and six replications. The treatments consisted of control TMR silage without BSF larvae (R1), 20% intact BSF larvae + 80% TMR silage (R2), 20% chemically defatted BSF larvae + 80% TMR silage (R3), and 20% mechanically defatted BSF larvae + 80% TMR silage (R4). Samples were placed in polyester bags and incubated in the rumen in sacco up to 72 h. Nutrient degradability was evaluated for each time point interval. Results revealed that the lowest dry matter degradability (DMD) was found in R1 compared to all treatments (p < 0.05), while the highest DMD was found in R2 (p < 0.05). The highest organic matter degradability was found in R2 compared to R1, R3 and R4 (p < 0.05). Addition of BSF larvae to TMR silage increased the crude protein degradability (p < 0.05). In conclusion, inclusion of both intact and defatted BSF larvae into TMR silage did not have any adverse effects on nutrient profiles and showed a good nutrient degradation values in the rumen.

Abstract

The purpose of this study was to analyze the factors influencing the production and the efficiency of pig farming input in Minahasa Regency of North Sulawesi Province. The location was determined using the multistage random sampling method, determining regency, districts, and village, which have the highest pig population in North Sulawesi Province, so that Minahasa Regency, and four selected Districts (Sonder, Kakas, Tombulu and Tombariri), then 2 villages/district were taken. The sample was determined using a simple random method by taking 25 farmers in each district so that the total sample was 100 pig farmers, then the data was taken in January-July 2019. Variables measured were the number of pig production, the number of sows, the number of piglets, the number of feed (corn, concentrate, rice bran) and the number of labor. Data were analyzed using the Cobb-Douglas production function model with multiple linear regression and marginal product values calculations. The results showed that the efficiency of pig farming inputs was larger than one, meaning it was inefficient. This condition is still possible to increase pig production by increasing the number of sows, the number of piglets, the number of feed (corn, bran, concentrate), and the number of labor.

Abstract

Microelements are important for stabilizing cell structures, but in deficient conditions they can stimulate alternative pathways and cause disease. This study was aimed to presents the monitoring data on the biogeochemical situation of pasture ecosystems in the Astrakhan region, southern Russia. Microelements in the collected samples from the pasture ecosystem, as well as the organs and tissues of Soviet Merino sheep, were determined by atomic absorption method. It was found a low level of microelements in soil, plants and forages of the ecosystem in the Astrakhan region. In addition, it was found a low level of microelements (selenium, iodine, and cobalt) in the organs and tissues of Merino sheep. Hypomicroelementosis in sheep leads to oxidative stress in animals, lower productivity and decrease the immunity of animals, which can be a predisposing for other diseases.

Abstract

Plantaricin IIA-1A5 is a bacteriocin produced by Lactobacillus plantarum IIA-1A5 which is isolated from Indonesian beef, and it inhibits activity of Gram negative and positive pathogenic bacteria. However, preparation of the antibacterial agent for further applications or studies is costly due to the usage of a bacterial medium. Therefore, this study was aimed to investigate the feasibility of cheese whey as a growth medium for production of the bacteriocin. The growth curve of Lactobacillus plantarum IIA-1A5 in producing antimicrobial compounds was found to occur in the logarithmic phase with an incubation time of 28 and 32 hours. Purification of plantaricin IIA-1A5 produced peptides with a molecular weight of 9.59 kDa consisting of whey and whey+ (20g/L sucrose, 12.5 g/L tryptone and 7.5 g/L yeast extract); thus, the peptide was grouped as class IIa (<10 kDa) bacteriocin. The protein concentration of plantaricin IIA-1A5 with whey+ (sucrose, tryptone, and yeast extract) treatment and whey treatment was 1883.17 mg/ml and lower than 325.58 mg/ml, respectively. Based on the antimicrobial activity test using a paper disc method, plantaricin IIA-1A5 demonstrated antimicrobial activity against Staphylococcus aureus ATCC 25923; the whey and whey+ treatment yielded 38.02 IU/dL and 321 IU/dL, respectively, while antimicrobial activity against Escherichia coli ATCC 25922 using whey and whey+ treatment yielded 44.85 IU/dL and 172.08 IU/dL, respectively. The effectiveness of the antimicrobial properties of plantaricin IIA-1A5 in the whey medium is proven through the results of this study. In short, the whey is appropriate growth medium for bacteriocin production.

Abstract

This study aimed to assess the effect of a mixture of garlic powder and Lactobacillus casei (GLC) on intestinal development, hematological parameters, nutrient digestibility, and performance of broilers in the starter phase. One hundred forty 1-day-old broiler chicks were divided into four groups, namely control (not given GLC supplement) and given GLC supplement either 1%, 2%, and 3% of total feed. Chickens were reared for 21 days in an open cage. On the 21st day of the experiment, blood collection, lymphoid organ and digestive organ weight, and performance data were recorded. Accumulative feed intake until day 21 did not differ (P>0.05) among treatment groups. In this study, there were improvements in the height of villi in the jejunum, and the acidity in the duodenum and caecum, due to the increase of short-chain fatty acids (SCFA: acetate and propionate). Protein and crude fiber digestibility in the GLC-given chickens was significantly higher than in the control group ((P≤0.05). GLC supplementation (1%, 2%, and 3% of total feed) significantly increased body weight gain and improved feed conversion ratio (FCR) (P≤0.05). In conclusion, the use of GLC during the starter phase can improve the nutrient digestibility, intestinal health, and performance of broiler chickens.

Abstract

The objectives of this study were to reveal appropriate growth models describing early growth of Kejobong goat based on Growth Hormone (GH) gene sequence analysis. A total of 35 DNA samples and 1.960 records of quantitative traits of Kejobong goat were collected. The exon 3 of GH gene was amplified and was sequenced to determine the SNP. Body weight and body measurements of the goats were taken at 0-14 weeks of age. Four non-linear growth models were applied for analysis of growth to compare growth performance of different genotypes by Non-Linear Mixed Model. A non-synonymous mutation (g1170AG) genotyped into GG, AG and AA was significantly associated with growth traits. Animals with heterozygous genotype AG showed higher growth traits than animals with homozygous genotype AA. Nonetheless, animals with homozygous genotype GG had the same growth traits with those animals with heterozygous genotype AG and homozygous genotype AA. The most fitted model for describing body weight was Von Bertalanffy model, while for describing wither height and hip height was Brody model. SNP at exon 3 of the GH gene can be used as genetic marker for improvement of growth traits of Kejobong goats.

Abstract

The main objective of the investigation was to observe the growth performance, carcass yield, meat quality, and intestinal morphology of broiler chicks with respect to the dietary crude palm stearin (CPS). The study was conducted on 200 birds and dividing them into two experimental groups viz control and CPS treated group with 10 replications of 10 birds in each. Chicks under the control group were fed basal diet only, however in CPS treated group chicks were fed the basal diet supplemented with 3% CPS. Birds were reared for 42 days and data regarding different parameters of study was recorded. Data were analyzed by student T-test and differences were considered significant at P < 0.05.Results indicated CPS treated group pertaining to lower final body weight, daily weight gain, feed conversion ratio, feed intake, dressing percentage, fillets, thight+drumsticks, and wings percentages. CPS treated group possessed lower liver, spleen, gizzard, and abdominal fat weights. Breast meat holds lower values for shear force, drip loss in CPS treated group, while cooking loss found vice versa. Abdominal fat breast in the meat and thigh skin possessed higher a* (redness) and b* (yellowness) values in CPS treated chicks, while breast skin and thigh meat hold lower a* and b* values in CPS treated chicks compared to control. Intestinal villus height, villus area and crypts depth in duodenum found considerably higher in the CPS treated chicks. Jejunum in CPS treated group possessed higher crypt depth but villus height and villus area remained lower. In conclusion, CPS impairs overall growth performance, carcass yield and meat quality but supports the intestinal morphology.

Abstract

The effect of caecotrope deprivation on growth, caecal metabolism and Volatile Fatty acid (VFA) production was studied in rabbits fed varying levels of dietary protein during a 42-days feeding trial. Fourty-eight mixed breed rabbits (average initial weight = 875±25 g) were divided into two groups viz; caecotrope consuming (CC) and caecotrope-deprived (CD) groups. Rabbits in the 2 groups were divided equally and assigned to 3 diets containing different crude protein (CP) levels (12, 15 and 18%) in a 2 × 3 factorial arrangement. The result revealed that increasing dietary CP improved (P<0.05) the proximate composition of the caecotrope. The live weight, weight gain, feed conversion ratio, nitrogen utilization and VFA production in CD rabbits fed diets containing 18% CP were comparable (P<0.05) with those of CC fed diets with 15% CP. Nitrogen utilization increased (P<0.05) following increasing dietary crude protein level. Molar proportions of acetate, butyrate, and propionate were higher (P<0.05) in CC rabbit compared to CD. Lactobaccilus acidophilus was isolated from the caecum of CC rabbits. It was concluded that caecotrope deprivation has detrimental effect on growth, nitrogen metabolism, VFA production and caecal bacteria and this effect can be attenuated by increasing the dietary protein level in growing rabbits.
