This study aims to detection polymorphism of β-lactoglobulin (β-LG) and its impact the yield of milk and chemical composition of Iraqi goats. in this project 75 local goats were taken with age (1.5-5.5 years), period of this study obtaining from 31-1-2023 for 28-5-2024, genotyping of this group by PCR-SSCP then sequencing for diagnostic the variation, genotyping and allelic frequency by PopGene32 software, milk samples taken in morning, analyzing by milk analyzer. Result show we have two allele T and A were 0.81, 0.19 respectively, whereas for genotypes frequency, TT and TA were 0.61, 0.39 respectively. χ2 calculated higher than χ2 standard, in average daily milk yield (ADMY) and total milk yield (TMY) there is a significant with TT vs TA, 0.872, 0.809 g/day, 119.84, 111.16 kg/day respectively, whereas milk composition there are a significant difference between genotypes, TA vs TT in lactose and solid nonfat 4.84, 4.44 and 8.72, 8.20 respectively. A difference between genotyping in ADM, TMY, LAC and SNF was observed so can be used a genetic marker in improvement programs that uses in goats breeding and farm animals.

The objective of this study was to evaluate the benefit of magnetically treated water (MTW) using in Awassi ewe’s farm during pre- and post-partum on lactating and some blood biochemical traits determination. This experiment was carried out in a private sheep raising sector, from September to December of 2021. Twenty-four Awassi ewes at 120-d of gestation, age 2.5-3-year, live weight of 50-55 kg, the ewes were distributed on four treatments: T0 the control (served drinking well water), T1 (magnetized water by using a device at strength 2000 gauss), T2 (magnetized water by using a device at strength 4000 gauss) and T3 (magnetized water by using a device at strength 6000 gauss).The results of using magnetically treated water led to increasing milk yield, improving milk physical (freezing point, PH) and chemical (fat, protein, lactose, SNF) characteristics, also improving the blood biochemical parameters concentration (total protein, HDL, oxidative enzyme LDH- Lactate dehydrogenase), however the MTW treatments led to decreasing the concentration of (creatinine, RBS (Glucose), total cholesterol (TCH), LDL and triglycerides (TG), enzymes: AST, ALT and ALP) concentrations at both pre- and post-partum periods in the all treatments of MTW compared with control T0. Finally, the results of 6000 gauss treated water show separatory then 4000 gauss in all parameters of the study.
