Salient Achievements:
1. In
urban and peri-urban areas majority of farmers follow sani method followed by
moist and dry concentrate mixture in feeding dairy animals. Feeding complete
feed system in dairy animals was observed to be superior over conventional
feeding system in terms of dry matter intake and digestibility of different nutrients.
Further ruminal biochemical parameters viz. total nitrogen, protein nitrogen,
TVFA and ruminal enzymes viz. carboxymethyl cellulase, xylanase, α and
β glycosidase were significantly higher in animals fed complete ration,
which may be advantageous in improving the utilization of different nutrients
for production purpose. The complete feed with green fodder was found
superior in terms of improvement in milk production in crossbred cattle as
compared to conventional feeding system and also complete feed without green
fodder. At farmers field, a feeding trial was conducted on lactating cows in
which feeding of complete ration increased milk production by 3 – 4 kg as
compared to the existing traditional feeding system followed by the farmers.
2. The enzymes produced by the ruminal
microbes digest fibrous feeds in ruminants. Techniques for the estimation of
fibre degrading ruminal enzymes have been standardized. Maximum activity of
fibre degrading enzymes was found in the particulate material (PM) fraction
at 2 hrs post feeding. The activity of xylanase and β-glucosidase was
significantly (P< 0.05) higher in
animals fed high roughage ration. The difference in the activity of various
enzymes with high roughage or high concentrate ration could be the result of
change in microbial population affected by diet composition. Mixture of
Bacopa monneiri (brahmi), Eclipta alba (bhringraj) and Urtica dioica
(bichchu) herbs at 1 % level in the concentrate mixture as feed additive in
the ration of heifers resulted in better growth and nutrient utilization. No
adverse effect of these herbs in heifers was observed as assessed from serum
biochemical constituents.
3. The transgenic cotton seed was found
to contain higher percentage of crude protein and ether extract as compared
to non-transgenic cotton seed. Both transgenic and non-transgenic cotton seed
had similar nutritional values in terms of feed intake, nutrients
oligestibility, milk yield and milk constituents and without any adverse
effect on health status of buffaloes as assessed from hematological
constituents.
4. Feed intake and palatability of urea
treated wheat/ paddy straw was increased. Milk production was increased in
crossbred cattle fed with urea treated wheat/ paddy straw. The animals fed urea
treated straw did not show any adverse effect. Urea concentration in the milk
of animals fed urea treated straw was estimated and the results revealed that
the qualitative test was negative while the quantitative test indicated that
urea in the milk was within safe limit.
5. Green to fodder ratio of 60:40 in
terms of dry matter availability was found to be adequate in growing and
lactating cattle. For growing heifers under farm conditions TMR containing
mustard oil cake is recommended for best result. Wheat bran is cheaper than
maize and could be used to the extent of 80 % of the requirement in
concentrate mixture. Lactating cows kept under field conditions produced
superior lactation performance with TMR-1, which contain mustard oil cake.
Lactating cows kept under farm conditions also produced more milk, consumed
lesser TMR containing mustard oil cake.
6. The effective dry matter
degradability revealed that cotton seed cake is less degradable compared to
mustard cake and linseed cake. Increased UDP level in the diet did not affect
the blood biochemical constituents and serum enzyme activities and might
decreased stress on hepatic tissue. Increasing UDP level from 41 % to 48 % of
dietary CP and also increasing plane of nutrition from 100 % to 115 % of NRC
requirements, though non-significant, but maintain a consistently higher milk
production and also there was an increase in body weight gain.
7. Supplementing the ration of lactating
cows with calcium salts of palm oil fatty acids (bypass fat) caused a substantial
improvement in the milk yield, 4% FCM yield, fat yield, and SNF yield in milk
of cow’s fed with bypass fat at 4% level. The ether extract digestibility was
improved in cows fed bypass fat and no decrease in crude fibre digestibility
was observed. These observations make the fact well evident that
supplementing the ration with bypass fat has no adverse effect on ruminal and
total tract digestibility. Analysis of milk fat revealed an increase of
unsaturated fatty acids like oleic acid, linoleic and linolenic acid in milk
of cows fed calcium salts of palm oil fatty acids. Increase in unsaturated
fatty acids in milk may be beneficial to consumers having heart problems.
Thus supplementing the ration of lactating cows with bypass fat improved the
milk production as well as milk quality.
8. Survey regarding existing feeding practices in villages of Haridwar, U.S.
Nagar, Nainital and Pithoragarh districts of Uttaranchal was conducted. In
districts Haridwar and U.S. Nagar, most of the livestock are generally stall
fed but in Nainital and Pithoragarh districts it was mainly the grazing while
some animals were reared on stall feeding. Green fodder given to the animals
were Berseem and Sugar cane top, Maize, jawar and grasses in Haridwar and
U.S. Nagar districts where as the tree leaves/ grasses (Bhimal, Gajjo, Bhatt,
Bhiyol, Paral, Shahut) and natural pasture as source of green fodder in
Nainital and Pithoragarh districts. Wheat straw and commercial pelleted
concentrate mixture was found as the main dry roughage and concentrate,
respectively for the feeding purpose of the animals in all the districts.
Feeding of mineral mixture to the animals were observed in villages of
Nainital and Haridwar districts, however, it was generally not fed to the
animals in U.S. Nagar and Pithoragarh districts. Supplementation of basal
feed with common salt has been observed in all the districts. Daily DM
intakes in buffaloes were found to be higher than of cattle in districts U.S.
Nagar, Nainital and Haridwar. CP intake ranged from 210-720 gm/ day in
different categories of cattle and buffaloes in districts U.S. Nagar,
Nainital and Haridwar while daily intake of ME (Mcal) ranged from 5.50 –
18.75 in these animals. Mineral analysis of fodder and concentrate samples of
Nainital and Haridwar revealed optimum level of all minerals expect Copper
which was found deficient in fodder. Cobalt was not detected in roughage and
concentrate sample collected from Nainital district. Serum mineral profile in
animals of Nainital district showed a deficiency of Phosphorus (Haldwani
tehsil), Zinc and Magnesium (Bhimtal tehsil), whereas Copper was found to be
deficient in both the tehsils. Cobalt was not detected in the serum sample.
In Haridwar district, the blood serum minerals concentrations were above the
critical level expect Copper and phosphorus. Mineral profile of soils of
district Nainital indicated the deficiency of calcium, phosphorus and
magnesium while Haridwar district showed a deficiency of calcium. Cobalt was
not detected in soil sample of districts Haridwar and Nainital.
9. Comparative study was conducted on
feeding of transgenic (Bt.) brinjal fruits vis-à-vis non-transgenic (non-Bt.)
brinjal fruits in 16 crossbred lactating dairy cows divided into 2 groups of
8 cows each along with concentrate mixture and green fodder as per the
requirement for 42 days. There was no significant difference in DM intake,
milk yield, milk constituents in terms of total solids, fat, protein,
lactose, ash content and body weight change between the groups of cows fed
transgenic and non-transgenic brinjal fruits. Bt protein in blood and milk of
cows fed transgenic brinjal fruits was not detected.
10. Three levels of supplementation of
soybean oil were investigated on lactating crossbred cows to study the effect
on milk yield and milk composition. Four per cent oil in the concentrate
mixture supplemented ration revealed improvement in the milk quantity as well
as quality in terms of unsaturated fatty acids.
11. Organic chromium supplementation in
broilers reduced serum total cholesterol, triglycerides, LDL-cholesterol and
glucose while there was increase in HDL-cholesterol of serum by organic
chromium supplementation. In broilers increased retention of crude protein
and ether extract by organic chromium supplementation has also been noted.
There was also improvement in FCR, weight gain and performance index of
broilers due to organic chromium supplementation.
