This study aims to see the extent of influence of oxytocin hormone induction on the nutritional composition of milk in the Etawah Crossbred  goat. This research was conducted in December 2018 in Syiah Kuala District, Banda Aceh, Indonesia. The examined parameters were the levels of fat, nonfat dry matter (BKTL), protein content, lactose content and milk density. The research used 18 Etawah goats and oxytocin hormone. A statistical unpaired t test indicated a highly significant influence (P <0.01) on the increase of milk fat injected with oxytocin hormone, i.e. 4.86% or 37.2% or higher than that without hormone injection. The milk density results showed  a significant effect (P <0.05) on the decrease in goat milk density (28.81% ) which was lower by 10.65% from that without hormone treatment. The level of nonfat dry matter (BKTL), protein content and lactose content had no effect (P> 0.05) in milk, i.e. 8.39%, 3.91% and 3.76%, respectively. In conclusion, hormone oxytocin injection had a highly significant effect on increasing milk fat levels and significantly affected the decrease in milk density but did not affect the level of nonfat dry matter (BKTL), lactose and protein.

In general, goat milk production is strongly influenced by the quality of feed given. This study aims to evaluate the type of forage fiber feed source that has an effect on quality of ettawah goat milk. The material used is 12 lactation crossbreed ettawah goat month 3rd. Feed given is concentrate and source of fiber (Pennisetum purpureum grass, Albizia chinensis leaves, Zea mays straw). The consumption of dry matter, milk production and milk fat content were observed as parameters. The results show that the combination of concentrate with Zea mays straw can increase milk fat content up to 0.9%. Milk production was not significantly different in each treatment. It was concluded that the combination of concentrate and Zea mays straw was recommended to increase the milk fat content of crossbreed ettawah goat.

This study compared selected parameters of milk and rennet cheese produced from milk obtained from alpine goats during winter and summer feeding under climatic conditions of the Warmia and Mazury region. Milk from the winter season contained more protein, less vitamin A and over seven times less vitamin E than milk obtained in summer. In cheese from the winter season, the content of dry matter, fat, protein and vitamin A was lower when compared with cheese from the summer period. The content of total biogenic amines in cheese was almost twice as high in winter than in summer (1056.4 vs 567.6 mg/kg). Winter cheese contained more cadaverines and histamine than summer cheese. The content of tyramine and putrescine was comparable in cheese from both seasons and was higher than the level of histamine. Milk fat from milk obtained in winter contained more long-chained SFA and MUFA in comparison with the summer period. Fat from cheese produced in summer had a higher content of SFA, CLA and ALA, whereas cheese from the period of winter feeding contained more C16:0izo and C18:1. The content of hyper- and hypocholesterolemnic acids was comparable in milk and in cheese with a slightly smaller proportion of hyper-acids and a slightly higher proportion of hypocholesterolemnic acids during summer feeding of goats. In conclusion, it was found that the feeding season had a minor impact on the chemical composition of milk, although it significantly differentiated the chemical composition of rennet cheese produced from that milk and the health quality parameters of both products. Milk from winter feeding had a higher content of protein, whereas the chemical composition of cheese was more beneficial in winter as the content of dry matter, fat and protein was higher. The health properties of both products were more beneficial in summer, which was determined by the profile of fatty acids and the content of vitamin A.

Background: Several single nucleotide polymorphisms had been detected in goats and for the researchers it is important to reveal candidate genes with substantial effects on the traits of economic importance. The aim of this study was to investigate the association between LPL, STAT5 and AGPAT6 gene polymorphisms and milk traits of goats. Methods: We investigated about 204 goats, four different breeds (Czech White Shorthaired, Saanen, Anglo Nubian, Alpine) and two crossbreeds (Saanen and Alpine, Saanen and Anglo Nubian). The milk samples were analysed using spectrophotometers LactoScope 550 and LactoScope FTIR (Delta Instruments, the Netherlands). The somatic cell count (SCC) in milk was determined by flow cytometry method using the Somascope CA-3A4 (Delta Instruments, the Netherlands). Variations of the goat AGPAT6, STAT5, LPL genes were detected by PCR-RFLP method. Result: Analysis of AGPAT6 gene revealed that goats with GC genotype had higher milk yield, fat content and lactose content; goats with CG genotype had higher protein content. STAT5 gene analysis showed that goats with CT genotype had higher milk yield; goats with CC genotype had higher fat content and lactose content; goats with TT genotype had higher protein and urea content and also SCC. According to LPL gene analysis, goats with CC genotype had higher milk yield while goats with GG genotype had higher fat and protein content. The highest milk yield was estimated in Saanen and Alpine crossbreed goats while the highest milk fat and protein content was estimated in Anglo Nubian goats.

The aim of this study was to identify the possible interaction between protein content in the diet and animal genotype, with respect to its higher or lower capability to synthesis α S1-casein in milk, in relation to the production, composition, and technological quality of the goat milk. Twenty-five goats of the Malagueña breed were used, with 13 of them belonging to genotypes with a high capability for synthesis of αS1-casein, and 12 belonging to genotypes with a low capability. The protein content in the diets were: 136 (D1) and 177 (D2) g/kg dry matter. Within each group, a milk production assay was conducted using the two different diets in a two-period balanced changeover design. Within each period, half of the animals consumed the D1 and the other half consumed the D2 diet. According to the results obtained it is deduced the change from D1 to D2 can be considered positive. In the low capability animals, this change would lead to the production of a greater amount of milk. In those with a high capability, this change would either give rise to the production of a greater amount of milk or to the production of a similar amount of milk but one presenting a higher αS1-casein content and, therefore, a milk with better technological quality.

Abstract. Title of the paper: Influence of systematic environmental effects on milk performance traits in German Improved Fawn The objectives of this study were to analyse the influence of fixed effects on milk traits of German Improved Fawn. The analysis was based on 27,778 test day records of 1,848 German Improved Fawn with 3,574 lactation records. The milk records were sampled between 1988 and 2002 from 229 flocks in Lower Saxony, Saxony and Baden-Wuerttemberg. The average daily milk yield was 2.87 ± 1.20 kg with a fat content of 3.08 ± 0.54% and a protein content of 3.38 ± 0.95%. Somatic cell count (SCC) was transformed into somatic cell score (SCS). Mean SCS was 5.49 ± 1.93. The average lactation length was 234.1 ± 76.4 days. The analysis of variance showed a significant influence of lactation number, stage of lactation, year of lambing and month of lambing on all analysed milk production traits. Milk yield was highest in the fourth lactation number and fat as well as protein content in the 7th to 13th lactation number. Litter size had a significant influence on milk and fat yield and on fat and protein content. The region significantly influenced protein yield and fat and protein content of German Improved Fawn but had no effect on milk and protein yield and SCS. Animals from Baden-Wuerttemberg reached the highest milk protein content but the lowest milk fat content.

Goats fed on high-quality and valuable forage provides the production of high quality milk and dairy products. In organic farming improper and poor feeding during lactation period reduce milk yield and quality of products. The goal of our research was to ascertain the post impact of different feedstuffs (oat meal, wheat bran, sunflower cake, rapeseed cake) on goat milk productivity and quality indices. The trial was carried out in farm “Bērzi”, Talsi district in autumn period for 60 days totally; it is, after including of these feedstuffs in feed ration. Sunflower meal fed in summer period increased in autumn period the content of goat milk fat by 6.7%, as well as by 7.5% increased protein content and decreased sugar content in milk by 0.5% compare to control. Rapeseed meal fed in summer resulted in increased milk fat by 5.1 % and decreased protein and sugar content in goat milk by 2.1 % and 1.6 % respectively in autumn period compare to control. The essential post impact p less then 0.05 on milk protein shown wheat bran which increased protein content in goat milk by 19.5% compare to control.

This paper is based on investigation of chemical and hygiene parameters of the quality of cow raw milk. Samples were collected on 10 collection spots of the dairy firm "Imlek", in 4 identical time intervals in the period of one month (20.06.2005.-20.07.2005.) in municipality of Gornji Milanovac, and research was carried out in the laboratory of "Imlek" in Cacak. Differences in chemical composition and hygienic quality of milk were analyzed, and slight variability was established between collection spots. Average content of milk fat was 3,89%, protein 3,20%, and dry matter without fat 8,56%. It was established that in regard to protein content there is significant and very significant statistical difference between collection spots. This is consequence of different nutrition, focus is on introduction of protein enriched feeds into nutrition of cows. High variability of number of micro organisms is consequence of inadequate, non-standardized obtaining (milking) and storing of raw milk. Average number of micro-organisms was 844.875/ml, and it varied from 112.000?5.000.000/ml. Average somatic cell count was 357.850/ml. Variance analysis determined that collection spots had statistically highly significant effect (P<0.01) only on protein content, whereas their influence on content of fat, dry matter without fat, number of microorganisms and somatic cell count wasn't significant (P>0.05). Individual testing (LSD test) established that milk collected from 7th collection spot had significantly higher protein content compared to other collection spots, which indicated that dairy heads of cattle consumed higher quantity of feeds rich on proteins and had better balanced diet in regard to ratio of energy and protein.

We evaluated the effect of grazing time of day on goat milk chemical composition, renneting properties and milk fatty acid profile in a Mediterranean grazing system. Sixteen lactating Girgentana goats were divided into two experimental groups and housed in individual pens, where they received 500 g/d of barley grain. For 5 weeks the two groups were left to graze in two fenced plots on a ryegrass sward as follows: morning group (AM), from 9·00 to 13·00; afternoon group (PM), from 12·00 to 16·00. In selected herbage, water-soluble carbohydrates (WSC) increased in the afternoon (204 v. 174 g/kg dry matter, DM; P=0·01), whereas crude protein (CP) and linolenic acid decreased (respectively, 16·7 v. 19·8% DM; P<0·01 and 26·8 v. 30·4 g/kg DM; P<0·01). Pasture dry matter intake (DMI) was significantly higher in the afternoon (0·82 v. 0·75 kg/d; P=0·026). Fat corrected milk production (FCM), milk fat and lactose content were not affected by treatment, whereas protein and titrable acidity (°SH) increased in the PM group (respectively 3·56 v. 3·42%; P=0·01; 3·55 v. 3·22°SH/50 ml; P=0·01). In contrast, milk urea content was significantly higher in the AM group (381 v. 358 mg/l; P=0·037). The results seem to indicate that an improvement in ruminal efficiency might be obtained by shifting grazing time from morning to afternoon, as a consequence of a more balanced ratio between nitrogenous compounds and sugars. Indeed, the higher linolenic acid and the lower conjugated linoleic acid (CLA) (respectively 1·02 v. 0·90, P=0·037; 0·71 v. 0·81% of total fatty acids, P=0·022) in the milk of goats grazing in the afternoon seem to indicate a reduced biohydrogenation activity in the PM group.

Flexography is an evolving printing technology that is suitable for printing on coated and uncoated paperboard and board, nonporous substrates including metalized and paperboard foils, and plastic films used especially in the packaging industry. This study evaluated the effect of paperboard and ink characteristics on flexographic print density in paperboard. Three commercial paperboards from different companies were prepared: brown kraft from Thailand, white kraft from Spain, and test liner from Iran. Four samples of process print inks from Iran were used in this investigation. Paperboard properties, such as roughness and water absorption, and ink characteristics, including solids content, PH and particle diameter, were measured. The inks were printed on paperboards using a roll no.15 applicator with a blade metering device, and the print densities were measured. Results showed that solids content, pH, and particle diameter of printing inks influenced print density, while the roughness and water absorption of the three types of paperboard had no significant influence on print density. Results also illustrated that two levels of ink viscosity (25–30 and 50–55 mPa·s) were insignificant to print density.

AbstractTesting blood and milk parameters as well as analysing the relationships among these markers is very useful for monitoring the internal homeostasis and health in high-yielding dairy cows during various production periods. The aim of the study was to assess the correlations (relationships) among macro-minerals, such as calcium (Ca), inorganic phosphorus (P), magnesium (Mg), other selected bone profile markers, such as total protein (TP), albumin, activity of alkaline phosphatase (ALP) measured in serum and selected milk components such as number of somatic cells (SCC), colony-forming units (CFU), milk fat (MF), milk protein (MP), milk lactose (ML), dry matter (DM), non-fat dry matter (FDM) and milk production in late-lactation cows. Both blood and milk samples were collected from 11 clinically healthy milking cows during the late-lactation period. The cows were examined once a day for 3 consecutive days resulting in 33 sets of blood and milk samples for laboratory and statistical analysis. Significant correlations were observed between: Mg and MP, Mg and FDM, ALP and SCC, TP and SCC, TP and MP, TP and FDM, albumin and MP, albumin and FDM, P and Mg, Mg and albumin, and between TP and albumin. When monitoring macro-mineral homeostasis and mammary gland health, especially in intensively fed high-yielding dairy cows correlations between these markers should be considered. The revealed correlations can allow for deeper comparative laboratory diagnostics of homeostasis and can be especially useful for laboratory monitoring of the potential risk of subclinical macro-mineral deficiency in high-yielding dairy cows.
