Abstract

The optimal storage temperature for preserve boar semen is 17-18°C. The temperature fluctuations can decrease sperm viability. The aim of this study was to obtain a boar semen extender for Artificial Insemination (AI) at a certain distance area. The observation was based on the sperm viability in modified Beltsville Thawing Solution (BTS) extender in different storage, and the effect of storage system i.e.: room temperature (22°C) and styrofoam box (18°C) were conducted for this purpose. The research used a completely randomized design (CRD) with two factorial i.e.: BTS and M-BTS extender (F1), room temperature and styrofoam box (F2). Semen from three years old Yorkshire boars (n = 3) were collected twice a week by glove hand method. Semen characteristics and their quality were evaluated macro and microscopically. These semen were added with BTS and M-BTS extender up to fourfold volume (ratio 1 : 3). This is based on the assumption of AI dose of 2 - 3 x 109cells/80ml and the sperm motility and viability were evaluated every six hours for 24 hours observation. The results showed that fresh semen characteristics were good, with the percentage of sperm motility 65.56±2.55% and sperm viability of 87.70±2.87%. The best extender found in this experiment of 24 hours observation was BTS extender with sperm motility 53.33±3.33% in styrofoam box. In conclusion, BTS extender can maintain the quality of spermatozoa stored in styrofoam box for about 24 hours with sperm motility 40%-50%, and the styrofoam box can be used as an alternative container for insemination program in the field. Key words: sperm viability, semen extender, storage, boar sperm

Abstract

The objective of this research was to determine the effects of dietary cation-anion difference (DCAD) on acidity of ration, blood, vaginal mucous, and urine, number of fetus, number of offspring, and offspring sex ratio. The treatments were rations with DCAD -28, -18, 0, +14, and +32 meq which were offered to 15 ewes. This research used randomized complete block design. There were three groups, (I) ewes previously had twin female offsprings; (II) ewes previously had twin male offsprings; and (III) ewes previously had twin male and female offsprings. Results of this study showed that there were no differences observed for blood's pH, vaginal liquid's pH, offspring number, and offspring sex ratio. Increasing DCAD affected ration's pH, urine's pH, and number of fetus for each ewe. Blood's acidity was not affected by DCAD, but DCAD -28 meq reduced acid of blood, metabolic acidosis, and urine; the number of fetus and offspring. DCAD -28 meq might be anions excessive in the ration. DCAD 0 meq was relatively the best of ration because gave the normality of blood, metabolic, and urine, also relatively the highest of fetus and offspring. The offspring sex ratio related to vaginal mucose pH when artificial insemination was applied (r= 0.75) and ration's pH (r=0.47). Ewes previously had twin female lambs gave the number of fetus and offspring sex ratio were 2.00+0.71 and 0%, respectively. Ewes previously had twin male lambs gave the number of fetus and offspring sex ratio were 2.80+1.30 and 15.00+8.50%, respectively. Ewes previously had twin male and female lambs gave the number of fetus and offspring sex ratio were 1.60+1.14 and 61.75+31.50%, respectively.Key words: DCAD, pH, offspring sex ratio, lamb, ewe

Abstract

Dendeng is a typical Indonesian jerked meat commonly made from sliced or ground beef with 2 mm thickness. This research was conducted to study the effect of kind of meat and leaching method on pH, toughness, protein, fat content and peroxide value (PV) of ground jerked meat. The experiment was set up in a completely randomized factorial design with three replications. The first factor was three levels of leaching methods (no washing, washed in 1.5 x 1.5 x1.5 cm size and washed minced meat). The second factor was kind of meat namely horse meat, lamb and beef. The results indicated that neither interaction effect between leaching and kind of meat nor effect of leaching were significant on all characteristics observed. Kind of meat influenced significantly on the pH, toughness, fat content and PV of dendeng (P < 0.01). Key words: dendeng, physical-chemical characteristics, leaching

Abstract

The aim of this research was to measure the relationship of the pH value to the somatic cell count as a parameter of sub clinical mastitis detection. Two hundreds quarter milk samples were used in this research and the test (the pH value, IPB-1 mastitis test and Breed method) was done in parallel way. The results showed that 152 samples from 200 samples (76%) tested with Breed method came from the herds which suffered from sub-clinical mastitis and with IPB-1 test showed that 145 (72.5%) of the samples had positive reaction. Using pH meter, it showed that 44 samples (22 %) had pH > 6.75, presumed suffered from sub-clinical mastitis and 2 samples (1%) showed pH < 6.30 (6.25 and 6.28). At the same time, these two samples showed a negative reaction with IPB-1 test and had somatic cell count of 360,000/ml and 280,000/ml, each. It also showed that there was a close relationship between pH value and IPB-1 test. The conclusion of this research was that the measurement of pH value was not a sensitive method for detecting sub-clinical mastitis. Key words: sub-clinical mastitis, pH, somatic cell count, IPB-1 mastitis test

Abstract

Phytate is commonly found in high concentration in rice bran. This compound can bind multivalency ions. The purpose of this study was to know the effect of rice bran in native chicken diet on Cd absorption. Twenty four native male chicks aged 3 months were randomly divided into six groups of treatments. The average weight of chick used in this experiment was 422.08 ± 39 g. The dietary treatments were 0% (R0), 10% (R1), 20% (R2), 30% (R3), 40% (R4), and 50% (R5) of rice bran in the ration given for 8 weeks. Drinking water containing 100 ppm Cd was given ad libitum. The results indicated that those treatments had no significant effect on Cd absorption, Cd concentration in feces, kidney, liver and weight of kidney and liver. Average of Cd in kidney and liver were 284.24 and 117.53 ppm respectively. It was concluded that rice bran in the native chick diet did not reduce Cd absorption. The utilization of rice bran and Cd pollution for long term period and in high concentration in the diet gave negative effect on native chicken performance. Key words: rice bran, phytate, cadmium, native chicken

Abstract

Six grass species (Pennisetum purpureum, Pennisetum purpureophoides, Sorghum sudanense, Brachiaria brizantha, Imperata cylindrica, and Panicum maximum) were harvested at 49 days and preserved as silage or as hay. Samples of silage and hay were evaluated by an in vitro gas production and in vitro nutrient degradability. Total gas production at 24 and 48 h as well as CH4 were higher (P < 0.01) in silage than in hay. Brachiaria brizantha had the highest (P < 0.01) gas production compared to other species, whereas P. purpureum had the highest CH4 production (mM/g organic matter degraded). Dry matter (DM) and organic matter (OM) degradations were higher (P < 0.01) in silage than hay. When compared with hay, silage had higher (P < 0.01) ammonia-N concentration (20.3 vs. 10.6 mg/100 ml) and higher (P < 0.05) butyric acid concentration (7.9 vs. 7.0 mM). Non-fiber carbohydrate (NFC) and crude protein contents were positively correlated with gas production (r = 0.51; P < 0.05) and CH4 production (r = 0.64; P < 0.01) at 48 h of in vitro incubation. However total gas and CH4 productions were negatively correlated with neutral detergent fiber (NDF) content. There were positive correlation between DM (r = 0.90; P < 0.01), OM (r = 0.93; P < 0.01), and NDF (r = 0.84; P < 0.01) degradations and gas production.

Abstract

Diarrhea is one of diseases in broiler chicken. Antibiotics are usually used to cure the disease. However, there are many risks caused by the use of antibiotic in poultry industries for human health. The risks are carcinogenic effect and resistance to the antibiotics. Therefore the use of antibiotics needs to be replaced by natural antimicrobes. One of the natural antimicrobes is bay leaves which contains volatile oils, tannins and flavonoids. This research was conducted to study the effect of bay leaves powder addition in the ration on the body weight, carcass percentage, carcass commercial cut and carcass cholesterol of the broiler using completely randomized design with six treatments and three replications. The research used 180 DOC (Day Old Chicken). The treatment diets were: R0 (control), R1 (control with infected Eschericia coli), R2 (1% bay leaves powder), R3 (2% bay leaves powder), R4 (3% bay leaves powder), R5 (antibiotic). The data were analyzed using analyses of variance and any significant difference was further tested by Duncan test. The results showed that the treatment diets did not significantly increase body weight, carcass percentage, and carcass commercial cut percentage. The treatment significantly decreased carcass cholesterol level. It is concluded that bay leaves meal could replaced the use of antibiotic in broiler ration and reduced carcass cholesterol. Key words: bay leave, E. coli, body weight, carcass, cholesterol

Abstract

A study aimed to identify the farmer practice in providing feed for their Bali cattle was undertaken at Satuan Pemukiman A (SPA) sub-village, Manggalewa sub district, Dompu, West Nusa Tenggara, a region of highly variable rainfall patterns and lengthy dry seasons. A critical aspect of this study was the detailed characterization of the availability, quality and usage patterns for existing forage resource within the SPA mixed crop-livestock farming system. The study found that SPA farmers used varying mixtures of free or tethered grazing and cut and carry to supply the forage needs of their cattle. The available grazing was of good quality and supply in the wet season but declined rapidly by early dry season. From mid-dry season on, the vast majority of farmers relied increasingly on cut and carry forage from a range of sources including volunteer pastures, crop residues, shrub legumes and finally other sources such as banana and papaya stem, cashew apple and native tree leaves in the late dry season. Despite some use of high quality shrub legumes such as Leucaena leucocephala and Gliricidia sepium the quantity and quality of available forage was often below maintenance, especially for lactating cows. The study also revealed that existing forage sources such as the shrub legumes L. leucocephala and G. sepium maintained high levels of crude protein and digestibility year round. Greater use of shrub legumes (especially G. sepium) and conserved forages have the potential to significantly reduce the feed gap in the second half of the dry season at SPA. Key words: Bali cattle, smallholder, cut and carry, pasture, shrub legume
