Abstract

African swine fever (ASF) is currently considered the serious contagious disease of the swine in-dustry worldwide. The feed and feed ingredients have been recognized as a potential risk factor for Af-rican swine fever virus (ASFV) transmission. No commercial vaccines and effective drugs against ASFV are available to date. This study aimed to examine the antimicrobial SALTEC™ 512, a formal-dehyde-based additive, at an application rate of 1.0; 2.0; and 3.0 kg/t feed against ASFV in complete swine feed. The effect of SALTEC™ 512 was evaluated by a contaminated ASFV feed assay. Our study reveals that SALTEC™ 512 inactivated ASF/VN/Pig/Hue/1270 strain in complete swine feed at an inclusion rate of 1.0 kg/t feed on Day 1 post inoculation. The most effective action was noticed at an inclusion level of 3.0 kg/t feed on Day 7 post inoculation. The antiviral activity of SALTEC™ 512 against ASF/VN/Pig/Hue/1270 was dose and time-dependent. Overall, SALTEC™ 512 may be a po-tential additive to reduce the risk of ASFV transmission via feed contamination.

Abstract

In view of the difficulties present in the swine production system to achieve sustainable productivity based on the comparative advantages and potential of the territory of the department of Caquetá, located in the natural region of the Colombian, the aim of the study was to analyze the socioeconomic factors that may influence the use of non-timber forest products (NTFPs) in live-stock feed. For this purpose, the study was carried out with a descriptive-transversal methodology with a non-experimental design and quantitative approach, where the survey was applied to 44 swine production units through a non-probabilistic method. The data were systematized using R software; a principal component analysis was performed and the degrees of relationship of socio-economic factors with the use of NTFPs in animal feed. It was concluded that despite being in a biodiverse territory, social factors related to the level of knowledge about NTFPs and economic factors linked to sources of financing are directly proportional to the degree of NTFP use in swine production in the department of Caquetá. Although NTFPs are found in most production systems in the region, they are not used for animal feed.

Abstract

This study was carried out to determine the dietary supplementation of organic zinc on feed intake (FI), feed conversion ratio (FCR), egg production (EP), egg mass (EM) and quality. A total of 120 ISA-Brown layers aged 20 weeks were used in this study. Hens were distributed randomly to four treatments (30 hens of each) with three replicates. The organic zinc was supplemented into basal diet at different concentrations as follows; (T1) 0, (T2) 100, (T3) 200, and (T4) 300 mg/kg. The results showed T2 was recorded improvement significant on FI, and FCR followed by T3. Also, egg mass in T2 was increased significantly compared with T1. The T2 and T3 were significantly higher in average egg production as compared to T1 which was showed the lowest value. There was no significant effect on egg quality when supplemented organic Zn to the diet of layer hens. It might be concluded that the dietary supple-mentation of 100 mg/kg of organic Zn has improved feed consumption which is reflected in the produc-tivity of laying hens.

Abstract

The study aimed to determine factors affecting economic profits of beef cattle business in Sakon Nakhon Province. A sample of 400 members of Kor Ror Por Klang Phon Yang Kham Livestock Coop-erative Limited was determined by using Taro Yamane method, and binary logistic regression analysis was used to analyze the data. The findings showed that the variables with the statistical significance of 0.01 included concentrate feeds, roughage, and the raised period of less than or equal to 12 months. They were statistically significant at 0.001 0.000, and 0.000 respectively, and the odd ratios were 1.387, 0.921, and 5.697 respectively. Additionally, the variables with the statistical significance of 0.05 includ-ed Charolais cattle (62.50%) and farm location. The two variables were statistically significant at 0.023 and 0.039 respectively with the odd ratios of 5.083 and 0.595 respectively. If the cows are fed on 1 more kg/day of more concentrated feed, it is likely for the farmers to increase economic profit by 0.921 times and 1.387 times respectively. The probability of economic profit is by 5.697 times if the cattle are raised no more than 12 months. The cross-bred cattle with 62.50% Charolais breed showed the proba-bility for the farmers to gain economic profit by 5.083 times. Finally, those who had farms located next to the farm family’s home were more likely to gain less economic profit by 0.595 times.

Abstract

Prolactin (PRL) affects egg production in duck as it induces broodiness and promotes follicles development. The objective of this study was to investigate the association between polymorphism of PRL gene and egg production traits in Alabio and Mojosari Ducks. Genomic DNA were isolated from 111 blood samples (51 Alabio and 60 Mojosari). PCR and sequencing were performed to identify poly-morphisms and genotype of the animals. Data recording of the ducks including body weight at 16 weeks of age and at first egg, average weight of three first eggs laid and egg number laid up to 3, 6 and 12 months production were collected. Data were analyzed using independent sample t-Test. As a result, two single nucleotide polymorphisms (SNP) were detected in intron 4. Both SNP C-5796A and SNP T-5817C were found to have association with egg number laid up to three months (P<0,005). The CA/TC genotype had higher egg number than CC/TT. These suggested that SNP C-5796A and SNP T-5817C could be potential markers for marker assisted selection to increase egg number in duck.
