The present study aimed to compare results for hatchability and growing performance of chicks from 2 biotypes, dual purpose (DP) and brawl (BR), in hipobaric conditions (2718 m above sea level). In experiment 1, a total of 352 hatching eggs were randomly arranged, 176 egg of DP y 176 BR. In experiment 2, a total of 114 one-day-old unsexed chickens were reared for 28 d. The experimental design for hatchability and chick performance variables was completely randomized with 2 treatments (DP and BR). There were no differences between the studied treatments for hatchability results (p>0.05). Hens’ biotype affected chicken performance in the rearing phase (p<0.01), where the DP chickens had better body weight and feed conversion than BR, but BR chickens had lower mortality than DP chickens.

Abstract KUB-2 chicken is an improved local chicken originally from KUB-1 chicken. KUB-2 has been assembled in the Indonesian Research Institute for Animal Production (IRIAP), and it has two sub-populations, namely KUB-2 Balai and KUB-2 kk. KUB-2 has dual purpose functions, for either meat or egg production. For farmers who raise a local chicken to yield meat, growth is an important trait. The study had the objective to evaluate the growth performance of KUB-2 chicken. About 2,540 6th generation KUB-2 chickens, consisting of 1,240 KUB-2 Balai and 1,300 KUB-2 kk were used in the study. Data were analyzed using a t-test. The average ten-week body weight of male and female KUB-2 kk was statistically higher than KUB-2 Balai (P<0.05). The ten-week body weight of KUB-2 Balai and KUB-2 kk chickens were 1,045.91 g and 1,211.80 g for males, and 832.74 g and 956.02 g for females. The feed conversion was 2.81 for KUB-2 Balai and 2.83 for KUB-2 kk chicken. For meat production, KUB-2 kk seemed more profitable compared to KUB-2 Balai since it had higher body weight and similar feed conversion. It also could be yielded at shorter age than KUB-2 Balai for the same body weight.

The aim of this research was to know the effect of organic chromium on feed which was limited to quail phase pre-layer production performance. The experimental design of the study was a Completely Randomized Design (CRD) consisting of twelve treatments, three replicates, and each replication consisted of five quails. Data were analyzed by variance analysis then tested continued with the Least Significance Different (LSD). The treatments were P0R1 (adlibitum feed, energy metabolism (EM) 2,900 kcal/kg, protein 22%), P0R2 (adlibitum feed, EM 2,800 kcal/kg, 23% protein), P1R1 (restriction feed 10% of adlibitum, EM 2,900 kcal/kg, 22% protein), P1R2 (restriction feed 10% of adlibitum, EM 2,800 kcal/kg, 23%.protein), P2R1 (restriction feed 20% of adlibitum, EM 2,900 kcal/kg, 22%protein), P2R2 (restriction feed 20% of adlibitum, EM 2,800 kcal/kg, 23% protein), P0R1Cr (adlibitum feed, EM 2,900 kcal/kg, 22% protein with adding 2 ppm chromium), P0R2Cr (adlibitum feed, EM 2,800 kcal/kg, 23% with adding protein 2 ppm chromium), P1R1Cr (restriction feed 10% of adlibitum, EM 2,900 kcal/kg, 22% protein with adding 2 ppm chromium), P1R2Cr (restriction feed 10% from adlibitum, EM 2,800 kcal/kg, 23% protein with adding 2 ppm chromium), P2R1Cr (20% restriction feed of adlibitum, EM 2,900 kcal/kg, 22% protein with adding 2 ppm chromium) and P2R2Cr (restriction feed 20% from adlibitum, EM 2,800 kcal/kg, 23% protein with adding 2 ppm chromium). Parameters observed included feed intake, body weight gain, and feed conversion. The results showed that the addition of organic chromium to the limiting feed had a significant effect (P<0.01) on feed consumption, body weight gain, and feed conversion. Organic chromium might give 2 ppm on feed that was limited to 10% of EM 2,900 kcal/kg adlibitum, 22% protein.

Meat Type

Selection of meat-type chickens is primarily focused on growth rate and body composition improvement. The negative relationship between growth and reproduction related characteristics makes rearing and breeding applications difficult. Although the studies on chicken breeding have more than 150 years of history, the speed-up have been derived only in last 75 years. While selection breeding birds based on their phenotype for such traits as skeletal integrity, body conformation, condition, morbidity etc. Over the years, progress has been made in terms of number of hatching eggs, egg weight and hatchability at the parent stocks. For the meat-type chickens, the average body weight gain was 8 g per day and feed conversion rate was 5.0 until the age of slaughter in the first quarter of the 20th century, whereas at the beginning of the 21th century, these characteristics reached 66 g and 1.7, respectively. Improvement in body weight and the feed conversion ratio of the genotypes which have been used for broiler production is because of the development in genetics. Besides these developments, some problems have surfaced regarding immune function, skeletal disorders, liability, and in the breeder level reproductive troubles.

Assessment of carcass and meat characteristics of Nellore young bulls or dairy crossbred young bulls fed two levels of grass-Convert silage in the rations (400 and 100 g kg-1 of dry matter). Sixteen Nellore young bulls and 16 dual-purpose dairy young bulls (Holstein x Gir and Holstein x Guzerá) with average initial body weight of 378.8±13.8 kg were used. The experimental design was completely randomized with treatments in a 2x2 factorial arrangement. The proportion of silage and the genetic group did not change the percentage of muscle, fat and bone of the carcass. The yield of the primary commercial cuts was not altered by the level of silage. The pistol cut weight was higher in Nellore young bulls compared to dairy crossbred young bulls (125.8 vs. 119.5 kg), while the relative weight of short ribs was higher in dairy crossbreds (11.9 vs. 11.5%). Only the muscle cut of the pistol was altered by silage proportion in the rations, being higher in those with the lowest proportion of grass silage. On the other hand, only the relative weight of flat, rump cap and edible lean trims were altered by genetic group, which were higher in Nellore young bulls. Among the characteristics of the meat, only marbling was significantly changed, being higher in dairy crossbreds fed rations with a lower grass-silage proportion. The genetic group did not alter the other meat characteristics. Nellore young bulls produce carcasses with higher yield of valuable meat cuts in relation to dairy crossbred young bulls.

Three hundred laying hens of two commercial and one experimental crossbreed were evaluated in Peruvian Andes. The Commercial crossbreeds were Babcock Brown and Improved Creole ISAMISA (CM), and local experimental crossbreed (CE). The experimental crossbreed was obtained from Naked Neck Creole Hens, legs feather Creole Hens and Babcock Brown (BB) commercial layer. The females were reared to 52 wk. of age, and recorded data included body weight, feed intake, egg number, and egg weight, allowing the calculation of egg mass and feed conversion ratio. The economic value of each crossbreed was determined by overall egg production and body weight at 52-wk old. The highest laying rate was exhibited by Babcock (76.9%) and CE (58.9%), followed by CM (53.1%). The crossbreeds differed in feed intake and in females’ feed conversion, with BB leading (2.55) followed by CE (3.49) and CM (4.32). In egg production, BB were the best, as expected from specialized tableegg crossbreeds. In summary, BB was the best egg-producing crossbreed, but poor in meat production. Better choice for dual-purpose production would be CE, ranked second in egg production. CM was the best meat-producing crossbreed and were second in egg-mass production. Hence, CE might be the best dual-purpose hybrid with better feed efficiency than CM and the consumers prefer large eggs and birds.

Potential Factor

Transmissible viral proventriculitis (TVP) of chickens is manifested in decreased body weight gains, poor feed conversion and weight diversity. Although TVP etiology has not been defined, a Birnaviridae family member, named chicken proventricular necrosis virus (CPNV) is considered as a potential factor of a disease. This study was undertaken in order to reproduce TVP and to evaluate its etiology. Broiler chickens of the TVP-infected group were inoculated with TVP positive proventriculi homogenate on the 24th day of life. Samples were collected, on infection day and 14 days post-infection (dpi). The 14 dpi anatomo- and histopathological evaluation, revealed that we have succeeded to reproduce TVP. TVP-infected birds gained 30.38% less body weight. In the TVP-infected group a seroconversion against picornaviruses, fowl adenoviruses (FAdV) and infectious bursal disease viruses (IBDV) was recorded with an ELISA test. Using RT-PCR and PCR, CPNV was detected in proventriculi and FAdV in spleens and livers of infected birds, 14 dpi. Our study supports that CPNV is involved in the development of TVP. We did not record the presence of IBDV in TVP or control birds, despite our recording of a seroconversion against IBDV in TVP infected birds. CPNV and IBDV belong to the same family, which allows us to assume serological cross-reactivity between them. The role of FAdV needs further evaluation.
