The Times

Three (3) female (rumen-cannulated goats) weighting 27.33±1.53 kg were housed in individual elevated metabolism stalls provided with 30% concentrate in the morning based on feed requirements (3% of their body weight (BW) dry matter (DM) basis) of the animals. Ad libitum feeding of napier grass follows thereafter. Clean drinking water were made available all the times in the respective animal watering troughs. All data were collected sequentially in every cycle of the study. There were 7 days lag period in every cycle for the animals to return to each natural state. On the 8 th day of every cycle animals were given different dietary treatment. Voluntary feed intakes were recorded for 3 days. This was done on the 11th to 13th day of feeding trial (3 days after treatment). The following were data collected, daily roughage dry matter intake (g/ kg metabolic body weight), daily concentrate feed intake (g DM/kg MBW) and daily total feed dry matter intake (g DM/ kg MBW). All data collected showed no significant difference (P > 0.05) among treatment means was observed. This implies that supplementing 3 to 5% dietary fats from two different sources (VCO and Lard) in ruminant diet do not influence the roughage, concentrate and total feed intake of mature female goats.

The acceptability and efficacy of. combinations of cowpea husk (CH) and maize milling waste (MMW) as feed for the goat were tested. The experiment, in a 4x4 Latin square design involved digestion trials with 4 West African dwarf grower goats weighing 8.2 to 9.6 kg. and about 4 months old. There were 3 experimental diets made up of CH and MMW in 25:75, 50:50 and 75:25 ratio of mixture. The control diet was 60 percent chopped Pennisetum purpureum plus 40 percent concentrate ration. The animals were fed at 5 percent of body weight. All trials lasted 80 days. Parameters for assessment were dry matter intake, protein and energy intakes and utilization. Feed intake values (%of body weight) in all experiemental diets were higher than 3 percent and increased with increasing levels of cowpea husk, Only the intake of 4.38% of body weight from 75:25 CH-MMW supported weight gain. Increases in MMW in the experimental diets resulted in significant (P<0.05) increases in dry matter digestibility. The crude protein intake and digestion increased with increasing inclusion of cowpea husk, but intake and utilization were not adequate at CH-MMW 25:75 and 50:50. The energy intake and utilization increased (P<0.05) across the treatment. Increasing levels of cowpea husk enhanced dry matter, energy intakes and energy utilization, Decreasing levels of cowpea, consistent with increasing MMW improved dry matter digestibility but not dry matter intake. The high crude fibre of cowpea husk is implicated. The utilization of the available energy in the mixture is limited by protein intake.

Data were collected during three visits to each of 19 dairy herds in the Guelph area. Feed intake, body condition and heart girth of all milking cows were recorded during each visit. Samples of all feeds were taken and analyzed for dry matter and acid detergent fibre. Cow weight was estimated from heart girth after grouping cows according to body condition. Milk production and fat test data were obtained from DHI records. Four regression equations were used to predict total feed dry matter intake. The mean daily feed intake was 2.8% of body weight. Eleven of the herds were within ± 10% of this value, four were above this range and four were below. The number of herds in which mean predicted intake was within ± 10% of observed intake, above this range or below this range, were (1) 7, 5, 7 (2) 12, 2, 5 (3) 11, 2, 6 (4) 8, 9, 2 for the four equations, respectively. Equations 2 and 3 were more accurate in predicting mean dry matter intake than Eq. 1 or 4.

This study aimed to assess the performance, carcass traits, and non-carcass components of feedlot finished Texel crossbred lambs from different residual feed intake classes (RFI). Forty-seven uncastrated male Texel crossbred lambs (¾ Texel + ¼ Pantaneira) tested here were 4-month-old with an initial weight of 29.9 ± 5.5 kg. The lambs were confined for 70 days for individual dry matter intake (DMI) and average daily gain (ADG) assessment. The diet containing corn silage was provided as roughage, while the concentrate consisted of corn grain, soybean meal, urea, and mineral mixture with a 40:60 roughage to concentrate ratio and 76.34% total digestible nutrients (TDN). After confinement for 70 days, the lambs were slaughtered to assess carcass traits and non-carcass components. Based on the RFI, lambs were divided into three classes according to the standard deviation (sd): Positive RFI (inefficient, 0.5 above the mean), Negative RFI (efficient, 0.5 below the mean), and Medium RFI (intermediate). Classes with Negative (efficient) and Positive RFI (inefficient) showed no differences in ADG (0.321 vs 0.306 kg; P > 0.05). Dry matter intake (g d-1), and percentage of body weight (BW) differed significantly between the RFI classes (P < 0.05). Compared to lambs in the inefficient class, those in the efficient class (Negative RFI) showed a 9% reduction in DMI and had the same ADG. The lambs in either Positive or Negative RFI classes showed no weight differences between non-carcass components (P > 0.05). The RFI classes showed no differences in shrunk body weight, hot carcass weight, hot dressing, and weight of commercial cuts (P > 0.05). They showed no differences in neck, shoulder + shank, loin, rack, flank steak, rack cap off, and leg weights (P > 0.05). Our results indicate that improvement in feed efficiency, as a function of the RFI index, does not compromise performance and carcass traits of Texel crossbred lambs.

Abstract Feed costs represent the greatest expense on a dairy farm, making feed efficiency an important trait to consider among production traits. Current tools to measure feed intake have limited application in commercial settings, due to affordability and lack of portability of technologies. Therefore, development of automated sensor-based indicator traits for feed intake could prove to be valuable. The objective of the current study was to determine if automated eartag data was associated with feed intake. Activity and inner ear temperature were collected every 19 minutes utilizing Quantified Ag eartags (n = 48 lactating cows). Ear tags were placed 5 days prior to the start of the trial, with cows ranging from 67-192 days in milk (DIM). Daily feed intake, milk weights, milk components and body weight (BW) were also recorded. Data were analyzed using PROX GLIMMIX in SAS. Dry matter intake (DMI) was modeled including fixed effects for DIM, milk weight, component composition, metabolic body weight (BW0.75), eartag activity or temperature, as well as the random effects of parity and group. To identify informative timeframes with reduced influence of environmental noise, data were analyzed over 3-day rolling windows of time. Six windows were significantly associated with dry matter intake (P ≤ 0.05) when utilizing ear tag activity. Three windows of time of ear tag temperature were found to be significantly associated with DMI (P ≤ 0.05). These findings indicate that eartag sensor data may be useful indicators of feed intake; however, days in milk and season may impact the informativeness of sensor data. Additional studies are warranted to validate the efficacy of activity and ear temperature as indicators of feed intake and determine the impact of other variables on these potential sensor indicator traits over time.

The study was conducted to investigate the performance of Uda rams fed concentrate diets containing graded levels of Camel's foot pod meal (CFPM). Sixteen (16) entire male Uda rams with an average initial weight of 30+0.0kg were allotted into four (4) dietary treatments in a Complete Randomized Design. Four (4) experimental concentrate diets were compounded with CFPM replacing soya bean meal at 0, 20, 40 and 60% levels of inclusion representing diets 1, 2, 3 and 4, respectively. The concentrate diets were offered to the animals at 1.50% of their body weight and concentrate feeding was adjusted on weekly body weight basis while rice straws were served ad libitum as basal diet. At the end of the 12 weeks feeding trial, a digestibility trial was conducted which lasted 21 days using three animals from each treatment. Parameters measured were dry matter intake, live weight changes, feed to gain ratio and nutrients digestibility. Results showed that the organic matter content of the diet containing 40% CFPM was highest compared to other diets. There was no significant difference (p>0.05) in dry matter intake and live weight changes among the treatments. The dry matter intake was higher in treatment 2 (993.02g) than in treatment 1 (932.32g) likewise the live weight changes was higher in treatment 4 (36.25kg) than treatment 1 (34.00kg). The feed to gain ratio ranged from 17.62 in treatment 4 to 25.42 in treatment 2. Nutrients digestibility increased with increasing level of CFPM in the diets. The DM, CP and ash digestibility were higher (p>0.05) in treatment 4 compared to the control treatment while the ADL was also higher (p<0.05) in treatment 4 than the control treatment. The optimum weight gain (36.25kg) and efficient utilization (17.92) was achieved at 60% inclusion level of CFMP. Therefore, Piliostigma reticulatum pods can serve as a potential fodder feed resource for ruminant fattening programme.

Dry matter (DM) intake was recorded daily for 12 pens of young bulls for 140 d in each of eight winters. Monthly means for DM intake ranged from 1.94 to 2.62 kg 100 kg−1 body weight (BW) and average daily gains (ADG) ranged from 1.15 to 1.46 kg d−1. Stepwise multi-variable procedures indicated that days on test (age) accounted for most of the variation in feed intake (partial R2 = 0.380). Climatic variables provided little additional explanation. Dry matter intake was scaled to 100 kg BW to minimize the influence of increasing weight with time. The multi-variable model which described weight-scaled DM intake included age (partial R2 = 0.509) and daily temperature (partial R2 = 0.013). Weight-scaled intake declined with age; the temperature effect represented a 2% increase in response to a drop in temperature from 0 to −15 °C. Equivalent increases in weight-scaled DM intake of 4.5 and 6.5%, respectively, were calculated by simple linear regressions based on daily or monthly temperature and intake values. Temperatures below −20 °C had no greater effect on intake or weight-scaled intake than those in the −10 to −20 °C range. It was also concluded that silage was unlikely to reduce DM intake at low temperatures and that European breeds of bulls had a twofold greater (P < 0.01) increase in weight-scaled DM intake in response to cold than did British breeds.

The aim of this study was to evaluate the effect of the supplementation of an enzymatic complex in integral diets for guinea pigs in the growing phase on productive performance. In total, 54 male guinea pigs (Synthetic line P 0.625) were used and submitted to a diet free of the enzyme complex (T1), and two experimental ones, one with 0.1% (T2) and the other with 0.2% (T3) of enzyme complex evaluated between two weeks of age (weaning) and after rearing (nine weeks old). It was statically evaluated and there were found no significant difference between treatments in relation to final body weight, weight gain, feed intake and feed conversion; and it was reported the weekly average of percentage of dairy dry matter intake by body weight.
