Abstract This study aimed to determine the optimal feeding time of microencapsulated sodium butyrate (SB) in whole milk (WM) and starter feed on growth performance and health in dairy calves. Forty-eight Holstein calves (age = 4 d; body weight [BW] = 39.45 ± 2.48 kg) were randomly allocated to 1 of 4 treatment groups (12 calves per treatment) in a completely randomized block design and fed (1) WM without microencapsulated SB (SB0) supplementation; (2) 4 g/d SB added to WM since d 4 to 32 (SB4); (3) 4 g/d SB added to WM since d 61 to 74 and equal amount was added to starter since d 75 to 88 (SB60); and (4) 4 g/d SB added to WM (since d 4 to 74) and the starter (since d 74 to 88) throughout the experiment (SBT). Calves fed SB4 and SBT had lower fecal score during pre-weaning, transition period, and overall period (P = 0.043, P = 0.05, and P = 0.015; respectively). In addition, calves in SB4 and SBT groups decreased the number of days with scours during pre-weaning period, and throughout study (P = 0.035 and P = 0.025; respectively). SB60 calves had greater serum total protein (P < 0.001) during post-weaning period. Post-weaning and overall albumin concentrations were greater in SB4 and SBT calves (P = 0.011), and tended to increase in pre-weaning period compared to control calves (P = 0.06). Based on these results, addition of SB in WM is recommendable for the first month of milk-fed calves life.

The positive effects of nucleotide (NU) supplementation in milk replacer have been elucidated in infants and in dairy calves; however, NU addition to whole milk has not been evaluated previously. This study aimed to assess NU supplementation in the whole milk on calf growth and health. Thirty Holstein calves (body weight: 39.1 ± 1.0 kg; 3 d after birth) were randomly assigned to the following treatments: whole milk without any supplementation (NU0), whole milk + 0.5 g/d added a NU-containing supplement to whole milk (NUCS0.5), and whole milk + 1 g/d added a NU-containing supplement to whole milk (NUCS1). Calves were weaned at d 55 and stayed on study until d 75. Calves had free access to feed and water throughout the study. Dry matter intakes (DMI) were similar among treatments (p > 0.05) during the pre-weaning period; however, increasing NU resulted in a linear (p < 0.05) increase in DMI during the post weaning period (2158, 2432, and 2518 g/d for NU0, NUCS0.5, and NUCS1, respectively). Treatments did not affect body weight (BW) at the first and second month of study, but final BW linearly increased as NU was added (87.1, 90.6, and 95.4 kg for NU0, NUCS0.5, and NUCS1, respectively). Neither pre-weaning average daily gain nor post-weaning average daily gain was affected by treatments; accordingly, feed efficiency was similar among treatment groups. Days with loose fecal score were linearly decreased as NU was added to whole milk during the first month of life, while the fecal score did not differ among treatments until the end of the study. No difference was observed in the skeletal growth of calves in the current study. Therefore, it can be concluded that NU supplementation in the whole milk has some beneficial effects on calf performance in terms of final BW, post-weaning DMI, and less days with loose feces.

Cutting Height

This study aimed to evaluate the production of Mombasa grass cultivation under two different systems: monoculture and silvopastoral, with heights of 70, 80, 90, and 100 cm. Two seasons were evaluated: rainy period (December to March) and rain/drought transition (March to June). The variables evaluated were: total dry mass (TDM), dry mass (DM) of the morphological components, number of tillers, efficiency of nitrogen use, DM content, number of harvest cycles and cutting intervals. The experimental design was a randomized block design with five replications. The monoculture system presented the highest yields of TDM, number of tillers and DM of the morphological components in the two evaluated periods. The main variable affected by shading was the number of tillers per area, which directly affects all variables linked to production. In addition to the type of system, the time of the year also influenced the production of DM of the grass. The evaluation of grass productivity in silvopastoral system evidenced that the plant tends to respond differently to cutting management when compared to the monoculture system. In the monoculture system, the recommended height for greater TDM yield and better leaf/stem ratio in the rainy period and the rainy/drought transition period was 80 cm, maintaining the residue height at 40 cm. As for SSP, cutting height of 70 cm presented the highest TDM and leaf/stem ratio for the two evaluated periods, maintaining the residue height at 40 cm.

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

Abstract This experiment was conducted to investigate the effect of 2 levels of crude protein (CP) content in the diet during transition period on lactation performance, colostrum quality and serum immunoglobulin concentration of dairy cows and their newborn calves. Thirty dry Holstein cows (607±75 kg) were blocked according to their parity and expected calving date, and then randomly assigned to one of 2 treatments of 15 cows in completely randomized block design. Dietary treatments were: 1) moderate CP level in transition diet (prepartum: 11.9%; postpartum: 14%); and 2) higher CP level in transition diet (prepartum: 14.2%; postpartum: 16.8%). Furthermore, milk samples were collected on two days (15 and 30) postpartum for milk composition analysis. At the same time, milk yield also was recorded. After parturition calves were fed mother’s colostrum. Colostrum samples were collected during the first milking postpartum. Blood samples of cows were taken on days 21 and 2 before projected calving date and on days 15 and 30 after parturition. Blood samples of calves were collected at 72 h postcalving and then on days 7, 14, 21 and 28 after birth. Applied treatment had no effect on average milk production on days 15 and 30 postpartum. Colostrum density was lower in cows fed higher CP level in transition diet than in those fed the diet with moderate CP content (P<0.05). However, the chemical composition of colostrum was not affected by CP level. Serum IgG concentration was higher for calves from higher CP group than for those from moderate CP level group at 21 days of age (P<0.05). In conclusion, the increased protein level during periparturient period tended to improve immune status of calves.

The availability of micronutrients in the niche defines the growth and yield parameters of chickpea. The present study was conducted to investigate the effect of different levels of biofertilizer with and without molybdenum on growth and seed yield of chickpea, at Seed Production Block, SGRR University, Dehradun, Uttarakhand. The experiment included seven treatment groups replicated thrice in Randomized Block Design. It was observed that all growth and seed yield parameters varied significantly with the application of different levels of biofertilizers with or without molybdenum. The observed results showed that all the plant growth parameters like plant height (54.67 cm), number of primary branches (5.34/ plant), number of pods per plants (64.00), fresh weight of plant (81.66 g) were maximum with treatment T6 (20 g Rhizobium+25 g PSB +0.3 g molybdenum/kg seeds). The number of nodules per plant (28.00) and 1000 seed weight (142 g) were recorded maximum with the application of treatment T7 (25 g Rhizobium + 30 g PSB + 0.3 g molybdenum per kg of seeds). The seed yield of chickpea was recorded maximum (15.67 q/ha) with the application of 20 g Rhizobium along with 25 g PSB and 0.3 g molybdenum per kg of seeds (T6). Thus, our findings indicate that, among all other treatments, the application of 20 g Rhizobium along with 25 g PSB and 0.3 g molybdenum per kg of seeds is suitable for higher seed yield of chickpea in Doon valley of Uttarakhand.

Caseinomacropeptide (CMP) index is a method used to detect adulteration of milk by addition of cheese whey, since CMP is a glycopeptide characteristic produced during cheesemaking, and soluble in the whey phase. The objective of this work was to evaluate the caseinomacropeptide index of UHT milk stored under different temperatures. Six batches of recently processed UHT milk were collected and stored under three temperatures (21ºC, 6ºC, and -12ºC) and analyzed by HPLC in the day of the milk collection (day 0) and at 30, 60, 90, and 120 days of storage. The experiment was run as a randomized block design with a 3x5 factorial arrangement, and the Student-Newman-Keuls (SNK) method was used as the post-hoc test (p = 0.05). There was a progressive increase of the CMP index during the storage period of 120 days, and this indicates the possibility of false positive results if the CMP index is used as an adulteration test for long term stored UHT milk. The validity of the CMP index as an adulteration indicator is only possible soon after packaging, and sample freezing is the only alternative when immediate analysis is not possible. The method was found to be precise, with robust CV of 1.9% even with high CMP levels.

Two experiments were conducted to evaluate the effect of including protected sodium butyrate (PSB) in the diets of laying hens of advanced age on productive performance and egg quality. In experiment 1, a total of 320 Dekalb White 61-week-old laying hens were distributed in a randomized block design to four treatments (0, 105, 210, and 300 g/ton of PSB) with eight replicates of 10 birds. The experiment was conducted over 112 days, divided into four periods of 28 days each. Productive performance and egg quality were evaluated. In experiment 2, a total of 58 000 Dekalb White 70-week-old laying hens were assigned to diets containing either 0 or 105 g/ton of PSB with two replicates of 14 500 birds. The experiment was conducted on a commercial poultry farm. Egg production and the percentages of broken eggs and dirty eggs were evaluated. The PSB levels did not influence the productive performance of laying hens. A quadratic effect was observed for eggshell thickness, percentage of eggshell and eggshell strength, reaching maxima at 193, 136 and 198 g/ton of PSB, respectively. A quadratic effect on yolk index reached a minimum at 181 g/ton of PSB. The percentages of dirty eggs and broken eggs were lower in laying hens fed 105 g/ton of PSB. In conclusion, the addition of PSB to the diets of old laying hens improved the eggshell quality and decreased the percentage of broken and dirty eggs Keywords: egg quality, laying hens, organic acids, performance, protected sodium butyrate

This experiment was conducted to examine the effect of various legume herbs supplementation on feed intake, digestibility and liveweight gain of fat-tailed lambs given Mulato (Brachiaria mulato) grass. Twenty four male fat-tailed lambs (8 months of age and 12.73± 0.56 kg (SE) of initial liveweight) were randomly allotted to four treatment groups based on unfasted liveweight.  Animals were housed in individual metabolism crates. The experiment was designed in a completely randomized block design, with four treatments and six replicates. The dietary treatment tested included Mulato grass ad libitum (M), M + Centrosema pascuorum  (MCP), M + Dolichos lab lab (MDL) and M+ Clitoria ternatea (MCT). All supplement was offered at 1.5% body weight (W) per day.  The experiment lasted for 10 weeks, with 2 and 8 weeks for adaptation and measurement period, respectively. The main parameter measured included feed intake, feed digestibility, and average daily liveweight gain (ADG).  Results showed that total DM intakes (DMI) were not affected (P>0.05) by legume herbs supplementation. Total DMI was 2.75, 2.79, 2.84 and 2.87 %W/d for lamb treated with M MCP, MDL and MCT respectively. In contrast, supplementation with various legume herbs significantly increased (P <0.05) DM digestibility (DMD) and ADG of lamb received Mulato grass, with no significant difference (P>0.05) between legume herbs.  Feed DMD was 58.17, 67.48, 64.91; 65.03% and ADG were 35.67; 58.39; 54.31 and 54.41 g/day, for lamb treated with M, MCP, MDL and MCT respectively. It was concluded that supplementation of legume herbs to fat-tailed lamb fed Mulato grass significantly increased DMD and ADG, but no significant differences across the legume herbs as feed supplements were observed.

The performance and profitability of three commercial broiler strains reared under farming system were investigated in this study. Day-old broiler chicks (n=156) of three different commercial strains (Hubbard classic, Cobb-500 and MPK) were assigned to three treatment groups in a completely randomized block design, each treatment replicated four times, 13 birds per replicate. The birds were reared from d1 to 35 days of age with similar housing, feeding and environmental management condition. Regarding to all parameters collected, live weight and body weight gain were higher (P<0.001) in T2(Cobb-500) group, while the birds of T3 (MPK) group were the lowest. Birds of T1(Hubbard Classic) and T2 (Cobb-500) strain group consumed higher (P<0.001) feeds, while the birds of T3(MPK) had the lowest feed intake. Cobb-500 broiler strain achieved superior (P<0.001) FCR, while the birds of T1 (Hubbard classic) strain group had poorer FCR. Liveability of the broiler strains was unaffected by all the treatment groups. Higher net profit and lower production cost observed in T2(Cobb-500) group than those of other strains, although the difference between the treatment groups was similar. The highly significant measurements of live body weight, weight gain and better FCR values were recorded for Cobb-500 broiler strain, followed by Hubbard classic and MPK, respectively. In conclusion, Cobb-500 broiler strain is appeared to be the most economic to rear amongst the three broiler strains investigated here in response to their performance records.
