Abstract

ABSTRACTThis research aims to know the impact of repeat breeding on the reproduction efficiency of dairy cattle in Enrekang Regency, South Sulawesi. It was conducted from April to November 2021 in Enrekang regency. This research used 102 dairy cattle of Friesian Holstein (FH). The research design used nonprobability sampling with the purposive sampling method. The samples were grouped based on three parities, namely Nuliparous, Primiparous, and Pluriparous. Prevalence data of repeat breeding was obtained from reproduction efficiency evaluation that was seen from a success of the first AI. If pregnancy does not occur in the first AI, it is repeated in the second AI until the third AI. The result shows that the prevalence of repeat breeding in dairy cattle of FH at the parity of Nuliparous had shown a lower percentage (3,44%) compared to the parity of Primiparous and Primiparous (31,57% and 29,62%). The prevalence of the three parities was tangibly different (significant) with p-value <0,05. Reproduction efficiency of dairy cattle of Nuliparous parity was higher than Primiparous and Pluriparous with value S/C (1,5 vs 2,76 vs 2,52) and CR (65,51% vs 47,36% vs 53,70%). The lower the prevalence value of repeat breeding, the better reproduction efficiency.Keywords: Conception Rate, Reproduction Efficiency, Repeat Breeding, Service Per Conception

Abstract

Batur sheep (Ovis aries) is one of the Indonesian native sheep that originated from Banjarnegara Regency. This study aimed to detect the FecXE allele of Bone Morphogenetic Protein 15 (BMP15) in Batur ewes using the sequencing method. A total of six (6) Batur ewes were randomly selected for investigation. The results showed that three (3) ewes were detected as carrier animals (FecX+/ FecXE), and the other ewes were wild-type animals (FecX+/FecX+). Unfortunately, this study did not observe a mutant animal (FecXE/FecXE). It can be concluded that the presence of the FecXE allele in Batur ewes may affect the prolificacy trait since previous studies reported that heterzygous ewes have the largest litter size traits than in wild-type ewes. Keywords: Batur sheep, BMP15 gene, litter size, sequencing,

Abstract

Australia's modern Brahman Cross (BX) cattle industry is based on animal welfare. The importation of BX cattle will be bound by the Exporter Supply Chain Assurance System (ESCAS) regulations. This study aimed to evaluate current increased price and fattening cost of feeder BX cattle along with ESCAS additional cost on the price of slaughtered cattle and their welfare. Based on the animal welfare assessment, while in the feedlot for 120 days were considered good, with the average value in the first month 86.4%, the second 88.5%, the third 92.14%, and the fourth 94.29%. Based on the calculations Activity Based Costing (ABC) method, it is known that procurement costs, including the purchase of feeders, contributed to 94% of the total costs, while other costs were handling costs 2.7%, cost of ESCAS 1.56%, selling cost 1.52%, and the lowest, maintenance cost 0.24%. Therefore, to fatten Australian BX cattle, special strategies are needed, such as: optimizing stock in the feedlot; efficiency cost in feed ingredients without reducing quality; applying animal welfare rules to minimize handling costs, and selecting vendors who want the lower price in providing ESCAS support facilities and establishing regular maintenance of the ESCAS supporting tools.

Abstract

Stocking density gives a significant role in poultry farming, with increasing the number of birds per unit space potentially leading to higher profits. The wider the pen will increase the need litter for pen, rice hulls are commonly used as litter. Limited supplies, higher costs, and unavailability of suitable materials have encouraged the search for alternative litter materials. This study aimed to identify ideal stocking density and other litter material sources on native chickens. The material of this study was 324-day old chick (DOC) native chickens, reared for 10 weeks. The DOC was randomly divided into 9 treatment groups including a combination of 3 stocking densities (8, 12, and 16 chick/m2) and 3 litter materials (rice hulls, wood shavings, and corncobs) in 3 replication. A completely randomized factorial design was applied in the study then followed by Duncan's multiple range tests. The variables observed in this study were litter temperature, litter pH, water holding capacity, ammonia level, final weight, feed consumption, body weight gain, and feed conversion ratio. The results showed that stocking density had only a significant effect (p

Abstract

Antibiotics Growth Promoter (AGP) are currently banned. Citrus leaves have active secondary metabolites that have the potential to be used as phytogenic feed additives. Many in vitro studies have reported the activity of lime leaves against E coli. Therefore, this study aims to integrate various studies in order to obtain comprehensive information on the activity of lime leaves against E coli with a meta-analysis. This research was conducted by collecting studies of citrus leaves from various species, origin, extraction methods, and different antibacterial test methods and comparing the treatment of citrus leaves with controls in inhibiting E coli by looking at the diameter of the inhibition zone. The results showed that kaffir lime leaves as an alternative phytogenic feed additive for AGP were effective in inhibiting E. coli. The inhibitory ability of E. coli bacteria was based on differences in the origin of lime leaves and extraction methods, while differences in levels, types of lime leaves, and antibacterial test methods did not affect the inhibition of E. coli. Citrus leaf extract at a low concentration of 5 mg/ml was able to inhibit E coli bacteria. Keywords: escherichia coli, lime leaf, meta-analysis

Abstract

The development of kacang goats based on the base area will encourage the formation of superior commodities in the North Insana District. This study aims to find out the base village area, relative spread/concentration patterns, and the specialization of the kacang goat development area in the North Insana District of TTU Regency. The study used survey methods and secondary data on the number of kacang goat populations in each village in livestock units (ST). Data were analyzed using Location Quotient (LQ), Localita (Lp), and Specialization (Sp). The results showed that four villages were recommended as kacang goat development base areas in the North Insana District of TTU Regency. Positive localita coefficient values ranging from 0.008-0.081 less than one (α £ 1) and the coefficient of positive specialization of 0.003-0.022 less than one (β £ 1) indicate that the cultivation of kacang goats is not concentrated in certain village areas in North Insana Subdistrict and that farmers in each village do not specifically cultivate kacang goats. The research concludes that kacang goats have the potential to be developed as a regionally superior commodity in the North Insana District, TTU Regency.

Abstract

Protein is known as the most expensive nutritional component of chicken feed, reaching 15% of the cost of feed, compared to other components. Silkworm pupae are an industrial waste of silk yarn spinning which has the potential as poultry feed with the advantage of containing 48%-60% crude protein and 18 amino acids. The purpose of this study was to determine the effect of Bombyx mori silkworm pupae supplementation on the productivity and physical quality of Lohmann Brown laying hens aged 60-72 weeks. The research material was B. mori silkworm pupae meal mixed in the ration. The research method used a completely randomized design (CRD) with 3 treatments, namely P0 (ration + 0% silkworm pupae meal), P1 (ration + 3% silkworm pupae meal) and P3 (ration + 6% silkworm pupae meal). Each treatment consisted of 5 replications with 3 chickens in each replication. The variables observed included the productivity and physical quality of laying hens. The results showed that the addition of silkworm pupae meal by 6% in the ration significantly increased (P<0.5) egg production, feed consumption, feed conversion and egg quality, especially shell weight (g).
