Abstract: The objective of this study was to determine the
effects of garlic oil (Allium sativa), turmeric powder (Curcuma longa
Linn) and Monensin on Total apparent digestibility of nutrients in
Baloochi lambs. The experiment was designed as a 4 x 4 Latin square
using 4 ruminally baloochi lambs with 4 treatments in four 28-d
periods. Treatments were control (no additive), garlic oil (0. 4 g/d),
monensin (0. 2 g/d) and turmeric powder (20 g/d). Total apparent
digestibility's (% of intake) of organic matter (OM), dry matter (DM),
crud protein (CP), ether extract(EE), non fiber carbohydrate (NFC),
acid detergent fiber (ADF) and neutral detergent fiber (NDF) in the
total tract were not influenced by addition of either additives.
Abstract: In this study four Holstein steers with rumen fistula
fed 7 kg of dry matter (DM) of diets differing in concentrate to
alfalfa hay ratios as 60:40, 70:30, 80:20, and 90:10 in a 4 × 4 latin
square design. The pH of the ruminal fluid was measured before
the morning feeding (0.0 h) to 8 h post feeding. In this study, a
two-layered feed-forward neural network trained by the
Levenberg-Marquardt algorithm was used for modelling of ruminal
pH. The input variables of the network were time, concentrate to
alfalfa hay ratios (C/F), non fiber carbohydrate (NFC) and neutral
detergent fiber (NDF). The output variable was the ruminal pH.
The modeling results showed that there was excellent agreement
between the experimental data and predicted values, with a high
determination coefficient (R2 >0.96). Therefore, we suggest using
these model-derived biological values to summarize continuously
recorded pH data.
Abstract: The aim of present study was to assess the effect of
glucogenic (G) and lipogenic (L) diets on blood metabolites in
Baloochi lambs. Three rumen cannulated Baloochi sheep were used
as a 3×3 Latin square design with 3 periods (28 days). Experimental
diets were a glucogenic, a lipogenic and a mixture of G and L diets
(50:50). The animals were fed diets consisted of 50% chopped alfalfa
hay and 50% concentrate. Diets were fed once daily ad libitum.
Blood samples were taken from jugular vein before the feeding, 2, 4
and 6 hour post feeding at day 27. Results indicated that β-
hydroxybutyrate (BHBA), glucose, insulin and aspartate
aminotransferase (AST) were not affected by treatments (P > 0.05).
However, lipogenic diet increased significantly activity of Alanine
aminotransferase (ALT) and concentration of non-esterified fatty acid
(NEFA) in blood plasma (P < 0.05)
