. HE advent of the high-tech devices has accompanied by low physical activity but high consumption of westernized style high fat diet leading to high prevalence of obesity worldwide particularly in young reproductive ages of both man and women creating a highly risk factor for fertility disorders. However, the molecular mechanism underlying the link between overweight and infertility is still unclear. Therefore, the current study planned to uncover the association between weight-gain from high fat diet and the consequent infertility in male rats. The study recruited 30 adult male rats divided equally into two groups: the 1 st group was given normal diet and considered as a control group. The 2 nd group was served high fat diet (HFD) 60% buffaloes’ fat for 16 weeks to initiate similar to diet-related obesity. At the end of the 16 th week, blood samples, testicular tissue and semen samples were obtained and underwent biochemical, histopathological, gene expression and microscopical investigation. Compared to control normal diet fed rats, the obtained data showed that there was an increase in blood cholesterol and triglycerides in addition to the unwanted increase in body weight. HFD group showed down regulation of steroidgenic genes StAR and CYP17A with low levels of serum testosterone. Semen analysis taken from HFD males demonstrated low quality represented by low sperm count with reduced viability, motility and increased abnormalities. Testicular tissue sections of positive control group displayed degenerative changes with Caspase3 is crucial for the morphological alterations of cells as well as for the biochemical occurrences connected to the start and end of apoptotic processes and damaged cell indicator NLRP3 . In contrast, the same sections displayed marked decrease of inhibitor of apoptosis, survivin. Accordingly, it can be concluded that HFD induced obesity negatively affect male fertility through several mechanisms including general cardiovascular health concern of hyper-lipidemia, hormonal imbalance, low quality semen resulted from degenerative changes of testicular functional tissue.

. onsumption of sweets, primarily fructose, and high-fat diets has notably increased in recent years. This food pattern highly associated with the widespread prevalence of obesity and its subsequent health problems, This study aimed to assess the detrimental effects of consuming animal fat plus either fructose, glucose, or sucrose in amounts that matched their realistic proportions in human meals. Sixty male albino rats were divided randomly into four groups (15/group). During 64 weeks, control group was fed a normal diet, every other group was given a moderate-fat diet (MFD) mixed with different fructose (F-MFD group), glucose (G-MFD group) and sucrose (S-MFD group). Compared to normal rats, there was a significant rise in serum triglycerides of F-MFD, up-regulation of expression of lipogenic genes, ChREBP and SREBP-1c and the proinflammatory gene TNF-α with minimal hepatitis. However G-MFD and S-MFD showed similar or lower changes of the same analyzed parameters. Sections of hepatic tissues revealed severe lesions in liver of G-MFD group but normal to mild changes in either F-MFD or S-MFD group. It could be concluded that fructose sugar and fat have minimal morbid effects when consumed with regular concentrations.

INE lactating buffaloes between 2 nd and 5 th of lactating season , weighting 550-650 kg used after 6-8 weeks of calving through ''Swing-over design'' to study the performance of lactating buffaloes as affected by partial replacement of fresh berseem (FB) by maize silage (MS) or maize teosinte hybrid silage (THS). Control ration (CR) contained: 9.0% concentrate feed mixture (CFM) + 66.0% fresh berseem (FB) + 25.0% rice straw (RS). TRI contained: 15.0 % CFM + 35% FB + 20.0 % RS +30 % MS. While TR2 contained 15.0% CFM + 34.0% FB+20.0%RS+31.0% THS. Results indicated that all of the experimental rations were nearly similar expect DM and NFE. The differences in milk yield between CR and TR2 were a highly significant while no significant differences between both the TR1 and TR2 groups. There were no significant differences in all milk contents. The feed intake of DMI, TDNI and DCPI were nearly similar. Buffaloes fed TR1 and TR2 recorded the best feed efficiency compared with CR. The net revenue increased by feeding TRI and TR2. The inclusion of MS and THS in traditional winter rations led to increase daily yield of 7.0% FCM compared with control group, improve economic efficiency and could be save about 50% of FB produced which can be conserve it as silage or hay reduce cultivated berseem area by 53.75% to increase wheat production.

HIS study aimed to investigate the effect of in ovo injection of organic zinc and eggs subjected to high temperature (39.8 o C) during the late stage of incubation on post-hatch performance and immune response of local Egyptian strain (Bandarah) chicks. A total of 400 fertile eggs were weighed and randomly distributed to 8 groups with 5 replicates 10 eggs each. On the 14 th day of incubation, eggs were injected asT1: Eggs not injected (control), T2: eggs injected with 1ml saline solution, T3: eggs injected with 1ml saline solution containing 50µg Zn-Met, T4: eggs injected with a saline solution containing 100µg Zn-Met. Treatments from T1 to T4 incubated at normal temperature of 37.8 o c and 60%RH, treatments from T5 toT8 injected similar doses as described and subjected to high temperature of 39.8 o c when eggs are transferred from setter to hatcher machine for 3 hours at 18, 19, and 20 days of incubation. Results showed that in ovo injection with 50 and 100 µg Zn-Met/egg and subjected to high temperature during late incubation could improve hatching, chicks’ weight, antioxidant activities, and increased WBC , s and lymphocyte.

. HE goal of this research was to investigate how the impacts of added moringa dry leaves (MOL) to dairy cattle rations on white cheese (MWC) technological properties. Fifteen Friesian cows were divided into 3 equal groups and fed their nutritional requirement according to their milk production. The first group was served as a control without added moringa (T1), the second and third groups were fed with added 40g and 60g moringa/ head / day (T2and T3), respectively. Milk was obtained from the experimental cows after 30 days from feeding. The results indicated that cheese yield and contents of fat, total nitrogen (TN) and water soluble nitrogen (WSN) were higher significantly (P<0.05) for T3 than other treatments in fresh and at the end of the storage period. Total volatile fatty acids were almost similar the values in all treatments. Total plate counts of bacteria (TBC) were decreased being 9.67, 8.46, and 7.49 (log cfu / g) for cheese in T1, T2, and T3, respectively. Escherichia coli ( E. coli ) count was not detected in any treatment. The minerals content of cheese in T3 were increased in phosphorus and calcium. The cheese made from cow’s milk in T3 were recorded the highest value of α-Linolenic (omega3, n-3) unsaturated fatty acids. Organolepetical properties of cheese in T3 were significantly higher , preferred and more acceptable than the other treatments. So, the present results indicated that adding MOL for dairy cattle ration resulting in a rise in the nutritional value of the cheese received.
