The objective of this study was to evaluate the effect of supplementing glycinate form of zinc, copper, iron and manganese on growth performance and some blood biochemical parameters of suckling calves. A total of 20 one-day-old Holstein calves were randomly divided into two equal groups. Until weaning on day 63, the control group received milk and basal starter diet containing whey protein as a carrier while the treatment group received milk containing 6, 1.5, 15, and 6 ppm of zinc, copper, iron and manganese respectively, together with basal starter diet containing 40, 10, 100, and 40 ppm of zinc, copper, iron and manganese respectively. To assess the growth performance, feed intake was measured daily, and calves were weighed weekly. Blood samples were collected on days 0, 21, 42 and 63. Supplementation with glycinate trace elements significantly increased serum albumin, glucose, and high-density lipoprotein and decreased low-density lipoprotein concentrations in suckling calves compared to the control group. Carpus lengths was increased in calves treated with organic trace elements compared to the control group (P<0.05). Also, serum concentration of zinc tended to be higher in calves received glycinate trace mineral supplement (P=0.05). However, supplementation of organic trace minerals had no significant effect on growth performance and concentration of alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase in serum. The results of this study showed that supplementing the diet of calves with glycinate trace minerals improved inflammation-related parameters such as albumin, low- and high-density lipoproteins, and energy metabolism-related parameters such as serum glucose. However, supplementation of glycinate trace minerals did not have a significant effect on the growth performance of suckling calves.

The effect of diets containing different sources of fat on milk production and composition, and mammary gland morphology of the 40 primiparous Saanen does was studied during the last two months of pregnancy to 12 weeks after kidding. Goats were divided into four groups of 10 each, based on the average initial live weight and were assigned to one of four experimental diets. The diets included a non-fat diet, diet containing saturated fat, diet containing roasted soybeans, and a diet containing extruded flaxseed. The results showed that during the whole experimental period, milk production in goats fed with diet containing flaxseed was higher than in goats fed with non- fat diet or saturated fat diet (P<0.05). The average daily milk production of goats fed a diet containing flaxseed in the first, second, third, ninth, tenth, and twelfth weeks of lactation was higher than that of goats fed non-fat diet or saturated fat (P<0.05). The percentage of protein, lactose, solids not fat, and milk solids in non-fat diet goats were higher than the other groups (P<0.05). The percentage of fat to protein ratio in goats fed a diet containing unsaturated fat was higher than in other groups (P<0.05). Consumption of diets containing unsaturated fats improved the volume, environment, and size of mammary gland quarters (P<0.05). In general, the use of fat supplements rich in unsaturated fatty acids such as soybeans or flaxseed, in the close-up and early lactation diets could improve lactation performance in primiparous Sannen goats.

In order to evaluate the effect of different levels of corn gluten feed on performance, immune responses, intestinal morphology and some blood serum biochemical parameters of broiler chickens, an experiment was conducted using 500 male Ross 308 broiler chickens in a completely randomized design with four treatments, five replicates and 25 birds per replication. The experimental treatments included levels of zero (control), 2.5, 5 and 7.5 percent corn gluten feed in the diet which fed to broilers from 15 to 42 days of age. The results showed that dietary inclusion of corn gluten feed up to 7.5 percent had no significant effect on average weight gain, feed intake and feed conversion ratiocompared to control treatment. Also, jejunal morphological indices and blood biochemical parameters including triglyceride, cholesterol, albumin, phosphorus and alkaline phosphatase concentrations, livability, European broiler index and feed cost per kg of weight gain were not affected by dietary treatments. Antibody titer in response to sheep red blood cell (SRBC) injection was higher in treatment containing 2.5 percent corn gluten feed comparing to other treatments (P<0.05). Based on the obtained results, corn gluten feed can be included in grower and finisher diets of broilers (15 to 42 days of age) up to level of 7.5 percent without any adverse effect on performance.
