Abstract Recently, DIO3 gene has been proposed as a candidate gene for litter size in pigs. Moreover, it was shown that polymorphism in this gene is associated with carcass traits. In this study we identified several SNPs within coding sequence of DIO3 by HRM method and performed association study between two polymorphisms and reproductive and carcass traits in pigs bred in Poland. Analysis of 350 pigs of Landrace and Large White breed revealed several significant associations for rs80999359, like period between the second and third parities (2IP)(P<0.0008) in the whole population, period between the third and fourth parities (3IP) (P<0.022), number of piglets born alive (L3NBA) (P<0.0084) and number of piglets at 21 days (L3NB21d) (P<0.0176) at the third parity in Large White as well as period between the second and third parities (2IP) (P<0.0012) in Landrace breed. The second polymorphism (rs80983654) was associated with 1IP (P<0.0218), number of piglets born alive at the fourth parity (L4NBA, P<0.027), number of piglets at 21 day at the fourth litter (L4NB21d, P<0.01), in the whole population, average number of piglets born alive (ANBA, P<0.01250), average number of piglets at 21 day (ANB21d, P<0.009), average interparity period (AIP, P<0.016), age at the first parity (1AP, P<0.003), (1IP, P<0.001, L4NBA, P<0.017, L4NB21d, P<0.005) in Large White breed. In contrast, we have found only few associations between DIO3 polymorphisms and carcass traits. rs80999359 was associated with backfat thickness (p<0.01) while rs80983654 with the weight of ham. Our results suggest that polymorphisms within DIO3 gene may be associated with reproductive traits.

Data from a swine breed development project provided estimates of the genetic correlation among six performance and carcass traits. The data from the new breed, called Managra, were obtained over a 7-year period. Most genetic relationships examined were such that selection for improvement of one trait would yield a favorable improvement in another. Both carcass backfat and live backfat probe were found to be negatively correlated with area of loin eye and length of carcass. A positive genetic correlation was found between post-weaning daily gain and loin eye area. A high positive genetic correlation was found between birth weight and loin eye area. An unfavorable association involved a positive genetic correlation between birth weight and backfat.Correction factors for effect of carcass weight on the magnitude of carcass trait measurements and differences in means between sexes were obtained.Heritability of the traits was estimated by paternal half-sib correlation. The estimates for carcass traits were moderately high and agree well with most other estimates reported in the literature.

This experiment was conducted to investigate the effect of rosemary powder in diet on blood metabolite and performance of broiler chickens. 180 one day broiler chicks were distributed in a completely randomize design with 4 treatments and 3 replicates and 15 bird in each. Experimental treatments were included: Control (without additive), 0.05, 0.1 and 0.2 percent of rosemary in diet. In 42 day of age one bird from each replicate was selected and slaughtering for carcass traits. The results were sowed use of 0.05 percent of rosemary could be significantly increased feed intake of broiler in starter period (p<0.05). Also use of 0.1 percent of rosemary caused to significantly increase broiler body weight gain in overall of rearing period than 0.2 percent group (p<0.05). Use of 0.1 percent rosemary in diet had a significantly  feed conversion ratio (FCR) than T4 (0.2% rosemary). Experimental treatments had no significant effect on carcass traits, except in liver percent weight, which had significantly higher in T2 group (p<0.05). Also experimental treatments had no significant effect on glucose, cholesterol, triglyceride level of broiler chickens in 42 day of age. The results of this experiment showed use of rosemary powder could be improved broiler feed intake in starter period.

Ghrelin receptor (GHSR) gene is candidate gene for growth performance in chicken by modulating growth hormone release from the pituitary by binding to its ligand of ghrelin. Ghrelin gene, or growth hormone secretagogue (GHS) gene, is well known as feed intake and energy homeostasis regulator in mammals and birds. The objectives of this study were to identify the polymorphism of the T1857C GHSR locus in Indonesian local chicken and to evaluate its effects on carcass traits. The gene polymorphism was identified using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) using Hin6I restriction enzyme. Effect of genotype on carcass composition was analyzed using SAS General Linear Model (GLM) procedure. The genotyping was performed on 343 individuals including Merawang, Pelung, Sentul, Kampung, broiler (strain Cobb, parent stock), F1 crossbred of Kampung x broiler (strain Cobb, parent stock), and F2 crossbred of Kampung x broiler (strain Cobb, parent stock). All individuals were successfully amplified and were resulted in a 470 bp PCR product. This locus was polymorphic with two alleles (T and C) and three genotypes (TT, CT, and CC). The T allele and TT genotype were predominant in all populations. Individuals with CT genotype were significantly had higher live weight at 26w, carcass weight, commercial cuts weights, and muscles weights than TT genotype in F2 crossbred of Kampung x broiler population. Association of the T1857C GHSR locus-polymorphism with chicken carcass composition has been described in Indonesian chicken, providing evidence that GHSR might be an important candidate gene for chicken carcass traits.

ABSTRACT: This experiment aimed to evaluate the effect of including glycerin in kid goats diet on intake, performance and carcass traits. Twenty intact male kid goats Boer crossbred were used, with body weight of 25.06±4.15kg and 8.00±0.66 months old, allocated in block design, with four treatments and five replicates. The treatments consisted on including dry matter basis (DM) of the diet of four levels of glycerin: zero, five, 10 and 15%, in replacing corn. It was not reported influence (P>0.05) of level of glycerin on intake of forage and feed conversion of animals. The concentrate and total DM intake were affected (P<0.05) for the level of glycerin in DM, with reduction in the animals that received the highest level. It was not reported influence (P>0.05) of level of glycerin on weight gain, carcass yield and percentage of cooling losses. However, the hot and cold carcass weight was lower (P<0.05) to the animals feed with 15% of glycerin. The inclusion up to 15% of glycerin in the diet of kid goats Boer crossbred, although did not affect feed conversion and performance, compromised the intake and carcass weight.
