Abstract

HSP90 and HSP70 genes (markers) were used with 45 genomic deoxyribonucleic acid (DNA) isolated from West African Dwarf goat breeds in Nigeria to determine the expression patterns amongst the heat shock protein genes. Polymorphism information content (PIC) of marker; was determined to ascertain the informativeness of the marker.  Fourty five numbers of samples were obtained from WAD goats which were apparently healthy from Osun, Oyo and Kwara State of Nigeria.   At the time of collection, the ambient temperature (0°C) and relative humidity (RH) (percent) were also recorded and this revealed that all the sampled animals were heat stressed.  Polymerase chain reaction (PCR) was carried out using each marker (heat shock protein gene) , isolated DNA, doublen distilled water and PCR Master Mix. PCR products generated were subjected to polyacrylamide gel electrophoresis on an ABI 3730 DNA Sequencer. DNA bands were scored based on size of ladder with Gene Scan 3.1.2. Bands obtained were designated as alleles and prepared into Excel Worksheet with Microsatellite Analyzer version 4.05 software and allele frequencies were generated. The results revealed allele A and C as major allele by marker SSR1 (HSP90) and marker SSR2 ( HSP70)  genes respectively with percentage value of allele A slightly higher than C , effective number of alleles for all loci of SSR1 was lower than the SSR2.. The heighest (Ne1) expected heterozygousity value of 0.40 was revealed by marker 2(HSP 70 gene) as against the lower value of 0.36 revealed by marker 1 (HSP 90 gene) in WAD goats.   PIC per gene or marker across populations ranged from 0.55 (HSP90 ) to 0.59 (HSP70) indicating that the markers were informative (PIC ≥ 0.50). In conclusion, the two markers (HSP 90 and HSP 70) could therefore be serving as bio-markers for selection and breeding programmes for thermo- tolerance in livestock animals especially WAD goats under thermal stress.

Abstract

This study aims to describe and analyze the Red Pig Farm business. This study uses a survey method through a case study approach on Mr. Ferry Wawo's pig farming business. Uses a quantitative descriptive method. The data collection period is from April 2024 - April 2025. The results of this study indicate that the Red Pig Farm has implemented good technical aspects such as feeding, maintenance management, housing, and disease prevention and this pig farming business provides income. Where production costs consist of fixed costs and variable costs as well as total costs, where fixed costs consist of; depreciation costs for cages and equipment, and tax costs for one year amounting to Rp42,897,143, for variable costs Rp244,203,043, the total cost of the Red Pig Farm livestock business for one year amounting to Rp287,100,186. The income of the Red Pig Farm livestock business for one year of production period is obtained from the sale of pigs and livestock that have not been sold (stock) where the number of livestock sold is 64 and livestock that have not been sold is 49 with a total value of Rp830,350,000. For the income of Red Pig Farm for one year amounting to Rp543,567,814. For the level of profit or income from the Red Pig Farm livestock business, based on the results of the R/C ratio analysis, the value obtained was 2.90 or RC ratio 1, so the business run by Mr. Ferry Wawo made a profit. The conclusion is that the Red Pig Farm pig farming business in Kelurahan Pangolombian, South Tomohon District, Tomohon City, is still able to demonstrate good performance and survive after the ASF virus outbreak, while also generating adequate income and having good prospects for future development.

Abstract

This study aims to evaluate the consumption of dry matter, organic matter, digestibility of dry matter, organic matter, and protein of pellet feed in KUB chickens containing indigofera flour (Indigofera sp). The method used was a completely randomized design with three treatments and six replications: (P1) commercial pellets, (P2) pellets with 5% indigofera flour, and (P3) pellets with 10% indigofera flour. A total of 18 chickens aged 10 weeks were placed randomly in individual cages. The results showed that indigofera (Indigofera sp) flour can be used up to 10% in the pellet ration of KUB chickens without reducing the digestibility of dry matter, organic matter, and protein.

Abstract

Abstract: This study aims to evaluate the effect of cassava leaf meal substitution (Manihot esculenta) in feed on the non-carcass performance of quails. The method used was a complete randomized design (RAL) with 5 treatments and 4 replicates, using a total of 140 quails. Feed treatment consists of: P0 (100% commercial feed), P1 (96% commercial feed + 4% cassava leaf meal), P2 (94% commercial feed + 6% cassava leaf meal), P3 (92% commercial feed + 8% cassava leaf meal), and P4 (90% commercial feed + 10% cassava leaf meal). The variables observed in this study include: non-carcass weight, non-carcass percentage, non-carcass weight of the head, neck, blood, legs, and feathers. The data obtained was then analyzed using multi-dimensional fingerprint analysis (ANOVA) at a real level of 5%, if it shows a real difference (P0.05), then it is continued with the Smallest Real Difference (BNT) follow-up test. The results showed that cassava leaf flour had a real effect (P0.05) on non-carcass weight, non-carcass percentage, and head and neck weight, but had no real effect (P0.05) on blood, legs, and feather weight. Further tests showed that in non-carcass weights, the control treatment (P0) was markedly different from all other treatments (P1, P2, P3, P4), and P1 was markedly different from P3 and P4, while P2 was not markedly different from P3 and P4. In non-carcass percentages, P1 differs markedly from P2, P3, and P4, but does not differ from P0, whereas P0 differs markedly from P2, P3, and P4. In head weights, P1 and P0 were markedly different, while in neck weights, P0 was markedly different from all other treatments. It can be concluded that cassava leaf flour can be used as a substitute in quail feed to improve non-carcass performance, especially in the treatment of 96% commercial feed + 4% cassava leaf flour.

Abstract

This study aims to analyze the profitability and carryingcapacity of a beef cattle farm in Mapanget Village, Talawaan District,North Minahasa. The respondent, Mr. Nicolaas Kandowangko, servedas the data source for this study and owned 54 cattle. This studyutilized a survey method through observation and in-depth interviewswith the sample farmers using a prepared questionnaire. The analysismethod used the profit analysis formula π = TR – TC, where π was thefarmer's profit (IDR/period), TR (Total Revenue) the value of revenueobtained from sales, and TC (Total Cost) the total costs incurred,consisting of fixed costs and variable costs. The study concluded thatMr. Nicolaas Kandowangko's beef cattle farm generated a profit of94,075,333 IDR. The research demonstrated that profitabilitydetermination of a beef cattle business was not only based on total salesrevenue but also on the capacity to meet the livestock's feed needs.Production costs per period were also taken into account. The R/Cratio Mr. Nicholas beef cattle business result showed that the businesswas worthy of further development.
