Abstract

This study was designed to determine the physiological response of blood and immune organs ofbroiler chickens fed on various concentration of dietary black cumin powder (BCP) during the dryseason. A total number of 100 unsexed one-day old Cobb broiler chicks were used and distributed to 5treatments (control, antibiotics and without BCP, 20 g/kg BCP, 40 g/kg BCP and 60 g/kg BCP) and 4replications (5 birds for each). Physiological responses of blood and immune organs were measured at30 day of age. Addition of BCP to broiler ration did not significantly effects on physical properties ofblood (leukocytes count, erythrocytes count, haemoglobin, hematocrit, monocytes, and eosinophils) andrelative weights of thymus and bursa of fabricius, but significantly (P<0.05) increased relative weightsof spleen when compared to control. It was concluded that the black cumin grinds (Nigella sativa) as afeed additive could not change the physical properties of blood, relative weights of thymus and bursa offabricius, but it increased the relative weight of spleen at the level of 60 g/kg BCP, which could reduceadverse effects of infectious diseases in broiler chicken.

Abstract

The purpose of this research was to study the effect of density and floor types on performance,physiological state and immune response of broilers. The research involved 368 male broilers of theNew Lohman strain aged 8 days which were raised up to 35 days at different densities and floor types.Floor types consisted of rice hull litter and bamboo slat were used as the main plot; while densities of 7,10, 13 and 16 birds/m2 applied as the sub-plot. The results showed that the final body weight gain of the35-day Lohmann broilers at densities of 7, 10 and 13 birds/m2 were 28.22, 24.43 and 19.27 kgrespectively, compared to 16 birds/m2 at 13.53 kg (P>0.05). Broilers in the bamboo slats floor hadlymph weight at 3.73 g compared to the litter floor at 2.55 g (P<0.05). Also, broilers in the bambooslats had average RHL (0.65) lower than broilers in the litter floor (0.79). It could be concluded thatbamboo slats best being used for broilers up to a density of 13 broilers/m2.

Abstract

Tujuan dari penelitian ini yaitu mengkaji pengaruh bawang putih (Alium sativum) dan Lactobacillus acidophilus sebagai sinbiotik terhadap kadar kalsium, protein serta masa kalsium, protein daging ayam broiler. Percobaan menggunakan 144 ekor DOC umur 7 hari strain Cobb dengan merk dagang CP 707 unsexed  dengan bobot 218,5 ± 8,87g,  digunakan rancangan acak lengkap (RAL) dengan 3 perlakuan dan 8 ulangan setiap unit percobaan terdiri dari 6 ekor. Perlakuan yang diberikan yaitu T0 : ransum basal; T1 : ransum basal + 2 ml sinbiotik; T2 : ransum basal + 4 ml sinbiotik. Parameter yang diukur yaitu kadar kalsium, masa kalsium serta kadar kalsium protein daging. Data hasil penelitian dianalisis menggunakan analisis ragam dengan uji F, apabila terdapat pengaruh perlakuan yang nyata dilanjutkan dengan uji beda wilayah ganda Duncan, dengan bantuan statistical analysis system (SAS). Hasil penelitian menunjukkan bahwa penambahan sinbiotik ekstrak bawang putih dan Lactobacillus acidophilus dalam ransum dengan level 2 ml/1 kg ransum mampu meningkatkan masa protein daging serta penambahan sinbotik 4 ml/1 kg ransum mampu meningkatkan kadar protein daging namun belum mampu meningkatkan kadar serta massa kalsium daging.

Abstract

This was study aimed to investigate the impact of stocking density and crude protein level on the performance, carcass characteristics, nitrogen (N) use, and ammonia emissions of Sentul Selected (Sensi)-1 Agrinak chickens. A total of 504 chickens were used in the 70-day analysis using a random ized block design with factorial pattern of 3 × 3 which was arranged in nine treatments and four repli cates. The administered treatment covered two factors, including stocking density (A) and crude pro tein level (B). The treatments were administered when chickens reached 5 weeks of age. The results showed that different stocking density significantly influenced (p<0.05) the average weekly feed con sumption per chicken at 6, 7, 8, and 9 weeks, but not at 5, 6, and 10 weeks. However, varying crude protein levels showed no significant effect on carcass weight, giblet weight, and total edible parts. There was also no significant interaction observed between stocking density and crude protein level in relation to carcass weight and edible parts. Furthermore, no significant differences were found in giblet and carcass weights between the two groups (p>0.05). The results showed that feeding Sensi-1 Agrinak chickens with a lower crude protein level of up to 14% did not compromise their performance, meat quality, protein digestibility, or ammonia emissions, but affected carcass characteristics.

Abstract

This study aimed to evaluate the effects of floor position in a multitier closed house on microcli-matic air quality and litter conditions. Fourteen thousand and five hundred unsexed Ross broiler chick-ens with a DOC body weight of 45.84 ± 2.40 g were placed on each floor of a three-tier closed house and allocated to a randomized block design consisted of 3 treatments and 18 replications. Each floor measured 12x78x2 m3. The maintenance procedure was applied according to the integrated partnership company guidelines PT Tumbuh Optimal Prima, with an observation period of 28 days. The treatments applied were as follows: T1= placement of broiler chickens on the 1st floor, T2= placement of broiler chickens on the 2nd floor, and T3= placement of broiler chickens on the 3rd floor. Microclimate condi-tions (temperature, RH, wind speed, temperature humidity index, wind chill effect, and calculated real feel temperature) and air quality parameters (NH3, CO2, O2, TVOC, and HCHO) were measured daily on each floor. Litter conditions, included water content, litter temperature, NH3 content, pH, and caking were measured weekly. The results revealed that during the starter phase (weeks 1–2), the microclimat-ic conditions and air quality of the 3rd floor were significantly better (P<0.05) than those of the 1st floor and 2nd floor, a trend was continued during weeks 3–4. Notably, the results obtained on the 1st and 2nd floors were still within the normal range for the broiler thermoneutral zone. Conversely, the 3rd floor litter was generally poorer, with significantly higher (P<0.05) moisture content, temperature, and cak-ing than the lower floors, particularly in weeks 3–4. However, broiler placement on different floors did not significantly affect the litter pH (P>0.05). In conclusion, the microclimatic conditions and air quali-ty of the 3rd floor were generally superior to those of the lower floors over the 4-week rearing period, whereas the litter quality was inferior.

Abstract

This study evaluated the effect of a feed additive combination, Morinda citrifolia leaf extract, citric acid, and Lactobacillus acidophilus (MCL) on broiler chicken performance, carcass traits, and litter quality. MCL contains bioactive compounds such as flavonoids, saponins, citric acid, and probiotic. A total of 200 broiler chickens (8 days old with average body weight 213.88 ± 8.9 g) were randomly assigned to four treatments with five replications of bird each: T0 (control), T1 (1% MCL), T2 (2% MCL), and T3 (3% MCL). Results showed that T2 significantly improved (P<0.05) body weight gain (BWG) and income over feed cost (IOFC). Water consumption and carcass weight were also higher (P<0.05) in T2. Final body weight was significantly higher (P<0.05) in all MCL treatments compared to T0. Feed conversion ratio improved (P<0.05) in T2 and T3. MCL supplementation enhanced carcass traits and litter quality. Cooking loss was lower (P<0.05) in T2, while drip loss and litter pH were reduced (P<0.05) in all MCL treatments. White striping was higher (P<0.05) in T1, and litter temperature was lower (P<0.05) in T2 and T3. These finding suggest that MCL is a promising natural alternative to synthetic growth promotors, improving productivity and probitability in broiler production.
