The pedigree information was supplied by the experimental farm of the Hungarian University of Agriculture and Life Sciences, who is responsible for the maintenance of the Pannon White rabbit breed. The studbook data of the registered animals up to 2022 were analysed. The active population in 2022 was chosen as the reference population for the current study. The complete generation equivalent was 12.11 whereas the average maximum generations was 39.15 for the reference population. All animals of the breeding stock were inbred, the average Wright’s inbreeding coefficient was 12.52 %. Kalinowski’s decomposition of inbreeding showed that inbreeding is originated mainly from the past. The proportion of rabbits having more than 30 GCI was above 30.02 % for the total population, whereas it was above 36.45 % for the reference population.

In Japanese quails, an overall score on female plumage condition was proposed to identify whether their male partner showed an aggressive profile towards them. This study delves further into the relationship between aggressive and/or sexual male Japanese quail performances and the plumage and skin condition of their female counterparts. We used an original "more rigorous" scoring system and a single female body areas approach, aiming to easily identify specific regions that are predominantly affected by male ' s aggressive and/or sexual behavior and could be used to predict male ' s performance. Additionally, this study investigates whether deteriorations in female plumage and skin condition induced by males when paired with a single female (1 male and 1 female) for pedigree purposes can also be similarly evidenced when females are housed for multiplication purposes in groups of 4 every 1 male. After 60 days of cohabitation, males were classified as low or highly aggressive based on the number of pecks recorded, and female skin and plumage status was evaluated. The study found significant positive correlations between male pecking and female's head and neck plumage and skin status, but no correlation between male sexual behaviors and female plumage and skin status. Using the male classification according to the extreme aggressive performance towards their female mate, females housed with highly aggressive males had worse neck plumage and head and neck skin status than females housed with low aggressive males. In addition, these highly aggressive males initiated more copulation sequences but achieved the same number of cloacal contacts as low-aggressive males. Regarding groups, highly aggressive males continued to express aggressive behaviors more frequently to the 4 females than those classified as low aggressive. It was observed that the female group housed with highly aggressive males had worse head plumage status than those housed with low aggressive males. Our findings suggest that the level of male aggressiveness can be discerned by examining the condition of the females' head and neck plumage, irrespective of whether they are housed in pairs LA - English DB - MTMT ER - TY - JOUR AU - Casellas, Joaquim AU - Vasquez-Gomez, Marta AU - Id-Lahoucine, Samir AU - de Hijas-Villalba, Melani Martin TI - Evidential segregation analysis for offspring sex ratio in rabbit and sheep populations JF - LIVESTOCK SCIENCE J2 - LIVEST SCI VL - 277 PY - 2023 PG - 7 SN - 1871-1413 DO - 10.1016/j.livsci.2023.105354 UR - https://m2.mtmt.hu/api/publication/34624008 ID - 34624008 LA - English DB - MTMT ER - TY - JOUR AU - Mogensen, Lisbeth AU - Kristensen, Troels AU - Kramer, Camilla AU - Munk, Arne AU - Spleth, Per AU - Vestergaard, Mogens TI - Production of organic beef from dairy bull calves in Denmark - Effect of different production strategies on productivity, carbon footprint and biodiversity estimated by modelling JF - LIVESTOCK SCIENCE J2 - LIVEST SCI VL - 276 PY - 2023 PG - 10 SN - 1871-1413 DO - 10.1016/j.livsci.2023.105319 UR - https://m2.mtmt.hu/api/publication/34621637 ID - 34621637 LA - English DB - MTMT ER - TY - JOUR AU - Soares, Leticia Carolina Bortolanza AU - Pires, Alexandre Vaz AU - Dias Junior, Paulo Cesar Gonzales AU - dos Santos, Isabela Jorge AU - de Assis, Rhaissa Garcia AU - Perna Junior, Flavio AU - Rodrigues, Paulo Henrique Mazza AU - Biava, Janaina Socolovski AU - Ferreira, Evandro Maia AU - Polizel, Daniel Montanher TI - Doses of orange (Citrus sinensis) essential oil for Nellore steers fed with a forage-based diet JF - LIVESTOCK SCIENCE J2 - LIVEST SCI VL - 277 PY - 2023 PG - 8 SN - 1871-1413 DO - 10.1016/j.livsci.2023.105357 UR - https://m2.mtmt.hu/api/publication/34598700 ID - 34598700 AB - The aim was to evaluate whether the doses of orange essential oil supplementation impact on dry matter intake (DMI), ruminal fermentation parameters, apparent nutrient digestibility, and methane production in Nellore steers fed with forage-based diet. A total of 32 rumen-cannulated Nellore steers (initial BW= 335 +/- 25 kg; age= 20 +/- 1 month) were assigned to individual pens in a randomized complete block design. Within block, steers were randomly assigned to treatments: CON= diet without orange essential oil (EO); 100EO= CON diet plus 100 mg orange EO/kg DM diet; 200EO= CON diet plus 200 mg orange EO/kg DM diet; and 500EO= CON diet plus 500 mg orange EO/kg DM diet. The main active compounds of the orange EO used were limonene (88.0 %) and myrcene (5.79 %). The experimental period lasted 28d, with 22d for adaptation and 6d for sample collection. From d23 to 27, samples of haylage, concentrate, and total fecal production were collected to determine the total tract apparent nutrient digestibility. Ruminal fluid was obtained from d28 at 0, 6, and 12 h after feeding to determine ruminal fermentation parameters and methane production. The difference was considered significant when P <= 0.05. No treatment effects were detected (P>0.05) to DMI or specific nutrient intake. The increasing levels of EO did not affect (P>0.05) the total apparent nutrient digestibility. No treatment effects were detected LA - English DB - MTMT ER - TY - JOUR AU - Steffl, A. M. Bot AU - Gonda, M. G. AU - Scholtz, M. M. AU - Macneil, M. D.

In the 1980 ' s, Afrikaner breeders became concerned about a perceived loss in fertility and the lack of attention to performance traits. The "infusion project" was developed to target short-comings of the Afrikaner breed with the introgression of Bonsmara alleles into Afrikaner cattle. However, documented evidence of resulting changes in the fitness of Afrikaner cattle is scant. A survival analysis of the infusion project's impact on longevity has been completed with the Cox model. The first backcross generation (BC1) and the initial Afrikaner-Bonsmara cross generation (F1) had the lower risk ratios at 0.815 and 0.837, respectively, when compared to the purebred Afrikaner indicating their greater longevity. The second (BC2) backcross generation did not differ in longevity relative to the purebreds (P >= 0.05). The infusion of Bonsmara impacted longevity in the short-term, possibly due to increased retained heterosis or the breed substitution effect. However, the effect on longevity diminished as the generations of backcrossing to Afrikaner progressed.

The experiment was adopted a 2 x 2 factorial arrangement design, one factor was the periods of supplementing sows with SL (d 80 - d 107 of gestation & d 108 of gestation - d 21 of lactation), the other factor was SL (0 mg/ kg & 1000 mg/kg). Eighty crossbred gestating sows were randomly divided into four treatments, a basal diet (BD) treatment (T1), BD + SL from d 108 of gestation - d 21 of lactation (T2), BD + SL during d 80 - d 107 of gestation (T3), and BD + SL from d 80 of gestation - d 21 of lactation (T4). The results showed that compared with T1, T2 increased piglet average weight, litter weight gain, the protein, whole milk solid (WMS) and non-fat milk solid (NFMS) contents in colostrum, the total protein (TP), globulin (GLB) contents and the catalase (CAT) activity at parturition, the CAT and total antioxidant capacity (T-AOC) activities on d 14 of lactation (P < 0.05), T3 decreased the concentrations of interleukin-6 (IL-6) and tumor necrosis factor-& alpha; (TNF-& alpha;) at parturition (P < 0.05), T4 increased the litter weight, piglet average weight, litter weight gain, rearing rate of piglet, the protein, WMS and NFMS contents in colostrum, the TP and GLB contents, CAT and T-AOC activities at parturition, the TAOC activity on d 14 of lactation, the concentrations of immunoglobulin (Ig) G and IgM of piglets at 14 d (P < 0.05), decreased the concentrations of IL-6 and TNF-& alpha; at parturition (P < 0.05). Compared with T3, T2 and T4 increased piglet average weight and litter weight gain, T2 decreased the total bilirubin (TBIL) content at parturition (P < 0.05), T4 increased the CAT, T-AOC activities at parturition and T-AOC activity on d 14 of lactation, the concentration of IgM of piglets at 14 d (P < 0.05). Two-way analysis of variance showed that the SL treatment during the late gestation increased the rearing rate of piglets, the WMS content in colostrum, the CAT, T-AOC activities at parturition (P < 0.05). The SL treatment during the perinatal-weaning period increased the litter weight, piglet average weight,litter weight gain, rearing rate of piglets, the protein, WMS and NFMS contents in colostrum, the TBIL, TP and GLB contents, the CAT and T-AOC activities (P < 0.05), decreased the concentrations of TNF-& alpha; at parturition (P < 0.05). In conclusion, SL supplementation from late gestation to weaning improved antioxidant capacity, liver function, colostrum quality and immunity in sows, the growth performance and immunity in piglets.

Our main goal was to promote the efficient use of mitogenome SNPs contained in commercial high-throughput SNP arrays. In collaboration with NEOGEN Genomics (Lincoln, NE, USA), we integrated 310 SNPs into the commercial GGP Bovine 100K SNP array. In doing so, we demonstrated how mitogenome SNPs can be used in high-throughput arrays to (i) analyze population structure and diversity, (ii) classify bovine haplogroups and identify introgression and/or upgrading, (iii) screen and identify pedigree defects, (iv) impute mitogenome information on maternal lineages to increase statistical power in estimating the effects of mitogenome variation on quantitative production traits, and (v) identify deleterious mutations found in humans. In addition, we have developed protocols and pipelines inte-grated with the Magellan v2.0 software to enable efficient and routine use of mitogenome information in cattle breeding and genetic diversity management. Finally, we have highlighted some other interesting opportunities for the use of mitogenome information in the near future. LA - English DB - MTMT ER -
