“…Results of numerous researches indicated that the addition of fat supplements to the diet had no effect on the apparent digestibility of cell wall contents (79,80), neutral detergent fibre (81,79,82,80,14,30) or acid-detergent fibre (79). However, other researchers reported an increase in apparent digestibility (83,4,84,6,(85)(86)(87) after the feeding diets containing fat. Improving digestibility in horses leads to a reduction in the risk of metabolic diseases such as colic (8).…”

To investigate the impacts of various sources of omega-3 on feed intake, digestibility, and blood metabolites in horses, this research was conducted. In this survey, 6 medium-sized Turkmen horses, aged 14 to 16 years, were used. The horses had no movement and health problems. This research was carried out in the form of a rotating design and included 3 periods, and each treatment had 2 repetitions in each period. In each experimental period, horses were randomly assigned to each of the 3 experimental treatments. The experimental treatments included C) Omega-3-free supplement (control treatment), R) Persialin flaxseed oil, and P) Persialin fat powder. At the beginning of each period, after the withdrawal period for the previous period, blood and feces samples were taken as the covariate factors, then the experimental treatments were consumed for 14 days, and after the adaptation to 100 grams of supplementing fat powder or flax seed oil, blood, and feces samples were taken at the end of the course. Fat supplements were added to the concentrate 1.5 hours before feeding the midday hay. The palatability was affected by the P treatment and was significantly lower than the R and C groups (P<0.05). But the difference between the two treatments (R and C) was insignificant in any of the periods. The digestibility of acid detergent insoluble fiber (ADF), crude protein (CP), ether extract (EE), and organic matter were not affected by any of the experimental treatments. Blood metabolites including glucose, cholesterol, triglyceride, total protein, and blood urea nitrogen were not influenced by experimental treatments. The serum albumin concentration of horses was affected by the R treatment in the first and third periods, but no significant difference was observed between the treatments in the second period.

“…Four horses males cannulated in the ileum with age of 36 months and average live weight of 350 kg were used in a 4 × 4 Balanced Latin Square. The experiment consisted of four periods of eighteen days each, being the first twelve days of food adaptation, three days for total collection of feces and three days for collection of ilealcontent [10] [11]. The equine were cannulated in the distal ileum, according to the technique described [12] with implantation of rubber cannulas "T" model.…”

The objective of this study was to evaluate the coefficients of pre-cecal, ileal digestibility, and glycemic response in cannulated horses fed with different starch sources. Four male horses were used in a 4 × 4 Balanced Latin Square cannulated in the cecum, with 36 months of age and average weight of 350 kg. The horses were fed with hay and the following sources of starch in concentrates: 1) corn (C); 2) oats (O); 3) sorghum (S); and 4) corn/oats (CO). The experiment consisted of four periods of eighteen days each, being the first twelve days of adaptation and six days to collect samples. There was no difference in cecal and ileal digestibility of starch, CP, ADF, NDF and OM among diets evaluated. However, horses fed with oats diet had higher values of pre-cecal apparent digestibility of DM in relation at the horses fed to sorghum and corn/oats diets. The values of CF digestibility were higher for equines fed with oats and sorghum diet compared to corn/oats diet. The horses fed with corn/oats diet had lower plasma glucose concentrations 30 minutes before the supply and higher insulin concentrations 210 minutes after ingestion of the foods. The digestibility of nutrients in equine diets, in pre-cecal and pre-ileal evaluation, presents significant differences, depending on the starch source provided, oat, corn or sorghum. The plasma glucose concentrations are directly correlated with the digestibility of starch.

Effects of Pharmacological Concentrations of Dietary Zinc Oxide on Growth of Post-weaning Pigs: A Meta-analysis

Pharmacological dietary zinc (Zn) concentrations of 1,000 to 3,000 mg/kg diet from Zn oxide have been found to increase growth in post-weaning pigs. However, results were inconsistent among studies. A frequentist meta-analysis, in which effects were numerically described with standardized effect sizes (Hedges's g), was conducted in order to identify and quantify the responses in average daily gain (ADG), average daily feed intake (ADFI), and gain to feed ratio (G/F) in post-weaning pigs upon dietary Zn supplementation from Zn oxide. The inability of independent continuous variables to explain significant heterogeneity obtained with fixed effect models necessitated the use of random effects models to calculate summary statistics. Dietary Zn supplementation increased (P < 0.05) ADG (mean effect size = 1.086, 95 % confidence intervals = 0.905-1.266, 26 studies, 72 comparisons), ADFI (mean effect size = 0.794, 95 % confidence intervals = 0.616-0.971, 25 studies, 71 comparisons), and G/F (mean effect size = 0.566, 95 % confidence intervals = 0.422-0.710, 24 studies, 70 comparisons). Zinc oxide provided a feasible alternative to in-feed antibiotics to improve growth in post-weaning pigs, and its reduction in diets due to potential environmental pollution will have to be negated by alternative feed additives and management strategies in order to prevent economic losses.
