The study was conducted to examine slaughter parameters of three genotypes of meat type chicken: F1 crossbred derived from crossing of light hen of indigenous breed Greenleg Partridge with heavy meat type cocks, F2 crossbred being an effect of re-crossing obtained crossbred C x GP with meat type males and medium growing Hubbard JA 957, designed for a longer, 9-week production. Chicken were reared till 63rd day of age. Examined parameters were: dressing percentage, breast and leg meat yield and fatness. F1 crossbred (C x GP) were characterized by rather low body weight, typical for slow growing chicken and good musculature, especially breast. Re-crossing with meat type cocks affected significant (P < 0.01) improvement of the slaughter parameters. F2 crossbred (C x (C x GP) reached high body weight, typical for medium growing chicken. In comparison with Hubbard JA 957 F2 crossbred had lower body weight, the same dressing percentage, better breast and worse leg musculature, and less abdominal fat. High breast meat percentage in carcass and less fatness suggested, that these chickens can be used in meat production, as a medium growing material designed for a longer fattening period (9 weeks).

The objective of the study was to determine beef production traits of dairy and dairy × beef breed crossbred heifers. The data from Finnish slaughterhouses included observations of 14 221 Nordic Red (NR), 6 348 Holstein-Friesian (Hol), 1 626 NR × Aberdeen Angus (NR × Ab), 1 136 NR × Blonde d’Aquitaine (NR × Ba), 802 NR × Charolais (NR × Ch), 487 NR × Hereford (NR × Hf), 3 699 NR × Limousin (NR × Li), 827 NR × Simmental (NR × Si), 531 Hol × Ab, 467 Hol × Ba, 438 Hol × Ch, 186 Hol × Hf, 1 249 Hol × Li and 393 Hol × Si heifers. Crossbreeding with late maturing beef breeds (Ba, Ch, Li, Si) had favourable effects both on daily carcass gain and carcass quality traits (conformation, proportion of high value joints) of the progeny when compared to purebred dairy heifers. No advantages in proportion of high value joints seemed to be obtained by crossbreeding dairy cows with Ab or Hf breeds, while the improvements in daily carcass gain and carcass conformation score were intermediate compared to the late maturing crossbreds.

Fattening performance and carcass compositions were compared between Akkaraman (A), Kývýrcýk x Akkaraman F2 (KAF2 ), Kývýrcýk x (Kývýrcýk x Akkaraman) first backcross (KAB1 ), Chios x Akkaraman F2 (CAF2 ) and Chios x (Chios x Akkaraman) fist backcross (CAB1 ) ram lambs. After weaning at 3 months of age, the lambs were fed ad libitum concentrate and 300 g of alfalfa hay per lamb, per day. Six lambs of each genotype were slaughtered at 45 kg live weight and the carcasses were evaluated. The average daily weight gain and feed conversion efficiencies were 284, 271, 279, 282, 274 g and 4.92, 4.81, 4.76, 4.89, 5.01 for A, KAF2 , KAB1 , CAF2 and CAB1 , respectively. Corresponding values for cold dressing percentages were 49.28, 48.89, 48.18, 49.15 and 46.79, respectively. The weight of various fat depots differed (P<0.001 or P<0.01) among genotypes, but the weight of major cuts as a percentage of carcass weight did not differ significantly among genotypes except for percentage loin (P<0.05). It was concluded that there were no statistically significant differences for fattening performance among genotypes and that KA crossbred lambs had a higher percentage of loin and a lower percentage of bone in some of the major cuts. Also, there was a tendency for genotypes with lower tail fat weight to have a higher depot fat.

The effect of different housing systems was evaluated on productive performances and carcass and meat quality of a “local grey” population of rabbits (G). To compare data obtained from G,commercial hybrid rabbits (H) were reared and fed under standard practice. Rabbits were reared as follows: 96 G in outdoor colony cages (O) and fed organic feed based on pelleted feed (oP) and alfalfa hay (H) - group GOoPH; 80 G in conventional indoor colony cages (I) and fed the same organic diet (GoPH) - group GIoPH; 96 G in I and fed conventional pelleted diet (cP) - group GIcP;88 H in I and fed conventional pelleted diet (cP) - group HIcP. Fifteen rabbits of each group were slaughtered at live weight of 2500 g (100 days of age for G and 87 days of age for H), carcass and meat quality parameters were assessed. HIcP showed the highest average daily gain (33.5 g/day;P<0.05) and GOoPH the poorest total feed conversion (5.6; P<0.05). G showed the highest slaughter yield (P<0.05). GOoPH showed higher loin proportion and the lowest LL pH at 45 min post mortem(P<0.05). HIcP produced LL and BF meat with the less intense colour and rich in ash. LL meat of GOoPH was the richest in protein. GOoPH and GIoPH LL meat showed higher amount of C14:0 and 18:1 n-9. GOoPH showed the lowest value of 18:2 n-6, and HIcP showed the highest value of 20:4 n-6 and the lowest amount of 16:1 n-7. The G yielded meat with higher nutritive value, and the best results were obtained when animals received both pellets and hay and were reared outdoor.

Molecular technologies based on markers indicating differences among individuals at the DNA level can play an important role in genetic improvement of carcass traits through marker or gene assisted selection. The purpose of this study was to map quantitative trait loci (QTL) of chromosome 3 affecting carcass traits on Japanese quail using microsatellite markers. Two white and wild strains of Japanese quail were crossed reciprocally and the F1 generation was created. The F2 generation was generated by intercrossing F1 birds. Phenotypic data including weights of hot and cold carcasses,carcass parts and internal organs were collected from 422 F2 birds. The total mapping population (472 birds) was genotyped for microsatellite markers. QTL analysis was performed using the least squares regression interval mapping method. Significant QTL were identified for hot and chilled carcass weights, liver weight, head percentage, uropygial gland percentage, intestine percentage, ovary weight, uropygial gland weight, pancreas percentage (0-36 cM with an additive effect),proventriculus percentage, head weight (6-20 cM with a dominance effect), and gizzard percentage (0 cM with an imprinting effect).

The study aimed at evaluation the effect of mannanoligosaccharides (MOS) and zinc-bacitracin (ZnB) administered continuously (+) or intermittently (+/-) upon growing performance, carcass and meat traits, blood profile and tissue morphology of growing rabbits. One hundred and twenty five, 25 days-old rabbits were distributed among 5 groups fed the same basal diet: the control group did not receive any supplements; MOS+ group fed mannanoligosaccarides at 0.083 g/rabbit/day;MOS+/- group fed MOS at the same concentration as MOS+ group, but only two days/week; ZnB+group received Zinc bacitracin at 0.083 g/rabbit/day; ZnB+/- group fed ZnB at the same level as ZnB+ group but only two days/week. The experiment lasted from day 25 to 81 of life. The mortality rate in the control group (36%) was higher (P<0.05) than in MOS+/- (12%) and ZnB+ groups (12%).MOS and ZnB administered intermittently increased (P<0.01) dressing percentage as compared to the control group. The liver percentage increased (P<0.01) due to use of MOS (+ or +/-) and ZnB (+). ZnB (+ or +/-) increased (P<0.05) the protein percentage of meat as compared to the control group, while the continuative administration of MOS was able to reduce (P<0.05) the fat percentage as related to the control group. Both supplements and both administration protocols increased (P<0.01) meat tenderness and water holding capacity in respect to the control group. Continuous ZnB administration had deleterious effects on liver, kidney and ileum morphology. MOS could replace ZnB from weaning to slaughter age of rabbits without negative effects on performance and blood profiles causing no alterations in tissue morphology as compared to the control group. In addition, the MOS can be administered intermittently, reducing the production costs.

The study of candidate genes, based on physiological effects, is an important tool to identify genes to be used in marker-assisted selection programs. In this study, a group of halothane gene-free, non-castrated, male Landrace pigs was used to study the association between polymorphisms in the PIT1 (n = 218), GH (n = 213) and GHRH (n = 206) genes and fat thickness, average daily gain, and the EPD (expected progeny difference) for fat thickness, average daily gain, and litter size. These genes are potential candidate markers because of their important physiological effects. The pigs were genotyped by PCR-RFLP, and the statistical model used to analyze the association between genotypes and the traits measured included genotypes as a fixed effect and age and weight as covariates. PIT1 polymorphisms were associated with fat thickness (P = 0.0019), EPD for average daily gain (P = 0.0001) and EPD for fat thickness (P = 0.0001), whereas GH polymorphisms were associated with fat thickness (P = 0.0326) and average daily gain (P = 0.0127), and GHRH polymorphisms were associated with the average daily gain (P = 0.0001) and EPD for fat thickness (P = 0.0004). These results confirmed the potential usefulness of these genes in marker-assisted selection programs for pig breeding.

The aim of the 3 × 3 factorial experiment on broilers was to investigate the effect of high dietary levels of potassium (K) and different levels of sodium (Na) on chicken performance, carcass traits, dry matter content in excreta and nitrogen balance. Three hundred and sixty one-day-old Ross 308 chickens were allocated to 9 groups, in 5 replicates of 8 (4♂ and 4♀). Chickens from 1 to 42 days old were kept in cages with wire floors to enable excreta collection, and were provided with water and feed ad libitum. The basal starter (days 1-14) and grower (days15-42) diets contained, as analysed, 1.73 g and 1.89 g·kg-1 chloride (Cl), 10.7 g and 10.8 g K and 0.69 and 0.94 g Na, respectively. Basal diets were supplemented with cations containing, as analysed, 12.2/11.8 g and 12.7/12.5 g·kg-1 K and 1.22/1.25 g and 1.68/1.61 g·kg-1 Na, for the starter/grower periods of feeding, respectively. The molar proportion of Na:K in diets used in the experiment ranged from 0.09 to 0.27 in the starter diet and from 0.13 to 0.25 in the grower/finisher diet; the dietary electrolyte balance (DEB) values varied between 255 to 349 and 264 to 336, respectively. During the starter feeding period, body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR) in the chickens were positively affected by increasing the Na supplement. Throughout the feeding period, Na supplementation improved BWG, FI and FCR and production index values and increased carcass yield. The dry matter content of the excreta was negatively affected by the K level in the diet; the 12.7 g K dietary content, in particular, caused a higher moisture content. The daily intake of nitrogen and nitrogen excretion grew when the dietary Na level was increased from 0.94 to 1.25 or 1.61 g·kg-1. The proportion of N retained to N intake decreased significantly when the dietary level of Na reached 1.61 g·kg-1, as compared to the proportion at a level of 0.94 g Na·kg-1. Interaction between dietary Na and K levels for BWG and other indices of performance, and for nitrogen utilization, confirm a dietary reciprocal relationship for both electrolytes.
