TRITICALE IN DIETS FOR YOUNG DAIRY CALVES

A study was conducted to compare feed intake and growth rate of young dairy calves receiving two levels of triticale (27.5 and 55% of a complete ration) with calves receiving barley diets supplemented with urea or soybean meal. Effect of pelleting the 55% triticale diet was also examined. Each experimental diet was fed to 10 dairy calves (five bulls and five heifers) from birth. Experimental diets were fed free choice throughout. Triticale (1967 crop) at both levels reduced weight gain and feed intake relative to the control diets; however, there was little effect on feed efficiency. Low levels of ergot contamination of the triticale may have played a role in feed intake depression. Pelleting the 55% triticale diet resulted in reduced feed intake, similar weight gain and increased feed efficiency. Rations containing urea resulted in reduced rumen levels of isobutyric acid.

Continuous Feeding

Thirty dairy heifer calves were reared from birth to calving on rations containing 0, 6.8 or 13.7% rapeseed meal in substitution for soybean meal. The level of rapeseed meal did not significantly (P > 0.05) affect feed intake, weight gain or feed efficiency of heifers up to breeding weight (330–340 kg). The level of rapeseed meal did not significantly (P > 0.05) affect reproduction or milk production during the first lactation. However, there may have been a trend for lower conception rate and milk fat production during first lactation with the higher level of rapeseed meal.

Although fumonisins are identified as responsible for alterations in weight gain, little information is available on their effects on expression of growth-related genes, especially for Nile tilapia (Oreochromis niloticus) fingerlings. In this study, Nile tilapia fingerlings were treated with increasing levels of fumonisin B1 (FB1) and fumonisin B2 (FB2) (diets of 0, 20, 40, and 60 mg/kg) to evaluate their effects on weight gain (WG), feed intake (FI), feed efficiency (FE), growth hormone receptor (GHR) and insulin growth factor 1 (IGF-1) mRNA expression in liver of this fish. All variables were evaluated at 15 and 30 days of treatment. Diet containing 0 mg fumonisin/kg was used as control treatment. Treatment with 20, 40, and 60 mg fumonisin/kg of diet significantly reduced WG (P<0.0001) and FE (P<0.0001), while GHR and IGF-1 mRNA expression was reduced both at 15 and 30 days of treatment. Feed intake was not affected by diets in any of the evaluated periods. These results indicate that fumonisins (FB1 + FB2) affect the growth of Nile tilapia fingerlings through mechanisms that involve reduction of GHR and IGF-1 expression.

Abstract This study was conducted to examine the growth performance and expression patterns of growth hormone gene and insulin-like growth factor in metabolic tissues of pigs fed different unconventional feed sources. A total of 45 growing pigs were randomly assigned to 5 dietary treatments at 9 animals per treatment and 3 animals per replicate. Treatment one (T1) comprise of whole maize (WM) which served as the control, T2: brewers dried grain (BDG), T3: cassava peel meal (CPM), T4: plantain peel meal (PPM) and T5: corn husk meal (CHM) at 35% inclusion in the diet. Data collected and analyzed includes; initial body weight (IBW), final body weight (FBW), average daily feed intake (ADFI), average daily weight gain (ADG), feed conversion ratio (FCR) and feed efficiency (FE). At the end of the feeding trial, three animals per treatment (one animal per replicate) were slaughtered; the duodenum and liver were collected and stored using RNALater prior to RNA extraction. Real-time qPCR was performed in 40cycles using the PowerUp SYBR Green reagent and analysed using the Delta-Delta Ct method. All data were subjected to analysis of variance in a completely randomized design. The results showed that the treatment diets had effect on growth performance with significant differences (P < 0.05) observed for average final weight, average total weight gain, average daily feed intake, feed conversion ratio and feed efficiency while the initial weight were not significantly different (P > 0.05). IGF-2 was differentially expressed in the liver and duodenum across treatments while significant differences were not observed in the expression pattern of the growth hormone gene in both tissues. This study showed promise for the use of unconventional feeding stuffs in pig feeding and reveals that genes influencing performance characters are differentially expressed in relation to the source of unconventional feeds used in compounding pig diet.

Randomized Design

Increasing concern about some animal production systems has placed considerable value on humanitarian breeding systems, aimed at ensuring animal welfare and comfort. Raising calves is one of the most important stages in a milk production system. This study aimed to evaluate and compare the performance of Holstein dairy calves raised by two farming systems: conventional individual (CI) and collective with automatic calf feeder (CACF). Fourteen, 15-day-old Holstein dairy calves having an average initial body weight of 40 kg, were used. The animals were distributed in a completely randomized design with seven animals per treatment. The variables evaluated were the milk and feed intake, body weight, hip height, thoracic circumference and daily weight gain. The average milk intake was lower in the CACF (3.5 L animal-1 day-1) than CI (5.1 L animal-1 day-1) system. However, the feed intake was higher in the CACF (1.205 kg animal-1 day-1) compared to CI (0.910 kg animal-1 day-1) system. Body weight, thoracic circumference, hip height and daily weight gain were similar between the two systems. The CACF raised calves had a higher concentrate intake and lower milk intake than the calves raised under the CI system.

Milk Feeding

Thirty-two male Holstein calves, beginning at 1 wk of age, were used to estimate differences in weight gain between two feeding levels and two feeding frequencies over a period of 3 wk. Calves were randomly assigned to one of the following four treatments: whole milk (WM) fed at 10% of body weight (BW) twice a day; WM fed at 10% BW, three times a day; WM fed at 12% of BW, in two feedings per day, or WM fed at 12% of BW, in three feedings per day. Body weight gains and feed conversions were 279 and 437 g per day and 12.02 and 9.51 kg whole milk per kilogram of gain for the 10 and 12% levels of feeding, respectively. There was a trend towards increased rate of gain and improved feed efficiency when calves were fed twice compared to three times a day. Cost of medication was not influenced by level or frequency of feeding. It was concluded from this study that feeding whole milk at 12% of body weight was preferable to feeding at the 10% level of intake. Key words: Milk feeding, level, frequency, dairy calves

Finisher Diets

An experiment was conducted, with objective to determine the feed consumption, final live weight, weight gain, feed efficiency and economy in broiler chicken fed with locally available low protein based diets (20 percent CP in starter and 18 percent CP in finisher) supplemented with methionine, lysine and homeopathic medicine alfalfa. For this hundred fifty day-old birds of commercial broiler (Vencobb) were randomly assigned to five dietary treatments(10 chicks/treatment) and replicated three times in CRD with treatments composition of low protein based diets (LPB) (T0), LPB+ 100g/100 met + 300g/100 lysine (T1), LPB + 200g/100 met +300g/100lysine (T2), LPB + Alfalfa 5ml/100 chicks 2 day in week with drinking water (T3) and LPB + Alfalfa 5ml/100 chicks 3 day in week with drinking water (T4). Synthetic methionine and lysine was used for supplementation of deficient amino acid. Same condition was applied in finisher diets of broiler chicken. The result showed that chicks fed with LPB in both starter and finisher diet had significantly (P<0.05) lower feed intake, final live weight , total weight gain, feed efficiency and income over feed and chicks cost (IOFCC) with compromising chicks fed with LPB with addition of methionine and lysine each and also homeopathic medicine alfalfa in starter and finisher period. Highest feed intake, final live weight, weight gain, feed efficiency was obtained with treatment (T1) followed by treatment (T2). However, positive growth response and better health status of chicks was also observed from supplementation of homeopathic medicine alfalfa with LPB and non-significant difference on Income Over Feed and Chicks Cost was obtained with treatment (T1). So, it was concluded that with supplemental methionine, lysine and alfalfa, the CP level of broiler chicks could be reduced up to 20 percent in starter and 18 percent in finisher diets without adverse effect on feed intake, final live weight, weight gain, feed efficiency and Income overfeed and chicks cost, provided under locally based feed ingredients.Int.
