The aim of the research was to obtain comparative indicators of the slaughtering and quantitative characteristics of the laying hens from different hybrid lines. For the examination were used hybrid lines from ISA Brown, for gaining eggs with brown shell, and DeKalb, for gaining eggs with white shell. The total number of examined individuals is 40, 20 of each hybrid line, with an average age of 84 weeks. After the slaughter, the measurements of each carcass were made and the participation of the basic parts in the mass of the clean carcass was determined. The dressing percentage of clean carcasses without internal organs and skin of hens from the hybrid line ISA Brown is 49.80%, while the dressing percentage of chicken from the hybrid line DeKalb is 46.80%. The average mass of chests (white meat with bone) is 234.65 g in ISA Brown, or 26.95% in the mass of the carcasses, while in the DeKalb hybrid line the average mass of the chest is 197.20 g with 26.86% participation in the mass of carcasses.

The objective of this paper was to discuss the level of somatic cell count (SCC) of milk in Holstein cows raised in Turkey. In total, 20 investigations conducted on Holstein breed Turkey (TR) and other countries (OC) were examined by SCC and effective non-genetic factors. The data were designed from the scientific journals on animal science published in the last decade. The means of SCC for TR and OC were calculated to be 486x103 cells/ml and 354x103 cells/ml, respectively. No statistical differences were found between two averages by log10 base. While parity, farm, month and stage of lactation were the significant factors affecting SCC for TR Holsteins, parity and calving season were the main factors for OC Holsteins. The findings revealed that reducing SCC have to be seen a priority target by the farm owners to achieve more productive herds.

Study aimed to analyze influence of some microclimate factors (light intensity, bird’s density and sex percentage) and litter material on semen quality (ejaculation volume) in broiler breeding males. Researches are part of a large study to analyze semen material and breeding efficiency of broiler breeding hybrid parents. Researches were performed during a two years period on ROSS 308 commercial hybrids with 25 roosters and 250 laying hens and three control weeks (25, 35 and 45) during breeding period (19-64 weeks). Three experimental groups were formed as one for each trial (A - with analyze parameters sub-standard and litter made of chopped straws; B - with analyze parameters above standard and litter made of rice hulls and C - with analyze parameters at the level recommended by the manufacturer of biological material and litter made of wood shavings). Ejaculation volume has been between 0.74 ±0.04 ml in week 25 - trial A and 1.20 ± 0.06 ml in week 45 - trial C. Results of trial B experiments are above the other ambient conditions with the exception of ejaculation volume in week 45. Results would seem to support usage of technological parameter values above standard recommendations and a litter made of rice hulls.

Study of average performances in a population have a huge importance because, regarding a population, the average of phenotypic value is equal with average of genotypic value. So, the studies of the average value of characters offer us an idea about the population genetic level. The biological material is represented by 93 Hucul horse from Prislop bloodline divided in 3 stallion families analyzed at 18, 30 and 42 months old, owned by Lucina Hucul stood farm. The average performances for cannon bone perimeter were 17.25 cm at 18 months, 18 cm at 30 months old and 18.57 cm at 42 months old. We can observe a good growth rate from one age to another and significant differences between sexes. The average performances of the character are between characteristic limits of the breed.

The paper aim to present the variation of body parts and the main characteristics of carcasses obtained from sheep youth of the Tsigai breed and crossbred (German Blackheaded breed x Tsigai breed) fattened in intensive system. The intensive fattening experiment developed over a 100-day time period was performed on Tsigai young male sheep (lot 1), and young male sheep crossbred German Blackheaded (GBH) x Tsigai (lot 2). The two batches of animals subjected under fattening were made up of 12 heads each. At the end of experiment were slaughtered 5 animals from each lot. The subjective assessment of the carcasses through the SEUROP classification system after conformation and the fattening status led to framing in a superior classification of carcasses provided from the crossbreds compared to those obtained from Tsigai breed. The warm carcass weight in crossbred and Tsigai breed recorded average values of 19.04 kg at GBH x Tsigai and 16.95 kg at Tsigai breed, with distinctly significant difference to the advantage of the GBH x Tsigai (+2.09 kg, p <0.01). Also, distinctly significant differences in favor of the batch GBH x Tsigai (+2.10 kg) were recorded regarding the cold carcass weights compared with the Tsigai breed batch. Regarding the main cut sections of carcass from young sheep submitted to intensive fattening, the crossbred lot recorded greater average values (in particular in the cuts of first quality - pulp and cutlet) compared to the Tsigai breed lot. In conclusion, the assessment of the carcasses according to subjective and objective methods highlights a higher potential of meat production and of better quality at GBH x Tsigai lot, compared with the Tsigai breed lot.

The study aimed a comparative analysis of the nutritional-economic characteristics of smoked products from wild salmon (Oncorhynchus keta) and respectively Norwegian salmon (Salmo salar) from aquaculture. Twelve samples (three samples for each type of study product) were analyzed. The proteins, lipids, collagen and water content was determined using the automated analyzer Food Check (infrared spectrophotometer); mineral substances were determined by calcination and the carbohydrates content and energy value were determined by calculation, using conventional relations. The most important differences between the products analyzed have targeted the lipid content: to the smoked Norwegian salmon fillets was determined an almost double amount of lipids (45.5 g/kg product) compared to smoked wild salmon fillets (23.5 g/kg of product). It is interesting the price difference between the two products under study, the product based on smoked Norwegian salmon fillets being over 40% more expensive than wild salmon.

The study followed the effects of combined add of fodder additives (YEA-SACC 1026+Actigen) on production and consumption indices and on health status in broiler chickens. The experiments were done on 50 Ross-308 broiler chickens, grouped in two lots, with 25 capita/lot and during 42 days. In the experimental lot, in the mixed fodder were added YEA-SACC 1026+Actigen in same proportion of 0.1%+0.08% in starter phase 1 (1-14 days), in production phase 2 (15-35 days) and in finishing phase 3 (36-42 days). For the control lot was used only mixed fodder. During the experiments were followed the average body weight, daily body gain and fodder consumption and conversion index, and for the health status were effected blood analyses. The combined use of probiotic YEA-SACC 1026+prebiotic Actigen in experimental lot determined the increase of body weight with 20.45%, daily body gain with 13.78% and the decrease of fodder conversion index with 7.32% given to control lot. The blood index analysis for glutation peroxidase (GPx) was better in experimental lot with 100.76 U/ml HT given to control one with 74.42 U/ml Ht.

Sentul chicken is a specific local chicken from Ciamis region in West Java and a dual- purpose type that can utilized for eggs and meat production. In other way, these birds are very good for chicken meat species, because they have a compact body and white skin colour. One of the alternatives to improve performance is by giving the ration added with a mangosteen peel meal (Garcinia mangostana). Mangosteen peel meal (MPM) is one of the medicinal plants used as a herbal medicine containing xanthone compounds as antioxidants, and antimicrobials. The research aimed is to find out of protein efficiency ratio of Sentul chicken fed diets containing mangosteen peel meal (Garcinia mangostana). This experiment used 100 day old chicks of Sentul chicken that were raised in cages until 10 weeks old. It was used completely randomized design, with four level of mangosteen peel meal (ration without MPM (R0), and ration that added 2.5% (R1), 5% (R2), and 7.5% (R3), of MPM, and five replications, each replicated consisted of five Sentul chickens. Protein consumption, body weight gain and protein efficiency ratio were parameters observed. The results that using mangosteen peel meal until 7.5%, gave no significant effect on feed and protein consumption, but the use of ration with the addition of mangosteen peel meal at 5% and 7.5% gave a significant effect on body weight gain and protein efficiency ratio. This research indicated that the addition of mangosteen peel meal (MPM) in the ration until 7.5 % gave the best protein efficiency ratio of Sentul chicken.

The aim of this study was to determine the effect of lameness on daily milk yield, milk fat and protein. 3378 data of 978 animals were monitored for all conditions (locomotion, milk production and milk content) during two years, monthly. The prevalence of lameness was different in several parity and stage of lactation. The effect of lameness on daily milk yield was complex and interacted with the stage of lactation. In the first stage of lactation the lame cows produced more milk than the not lame. The milk yield in the next period was almost equal, after the 120th day the milk production of not lame cows was higher than that of the lame cows. We conclude that lameness reduced milk production and milk protein content during the lactation. This same relation was not found in case of milk fat percentage.
